maybe its just me... but y are so many people on this board always "endyne this; endyn that" who is this guy that everyone thinks so highly of? ok i'v heard about his sc upgrade and other stuff... but y does everyone ride it like its the reatest thing in the world... to me he hasnt proven much... i know mech's here in ny that have proven something to me... thats who i trust... people are too easy to trust people many times... the advice i give on this board... who is to say i know **** about cars? i can say i know my fair share but how do u know that...

ok well im just babling now... i dink i drank a little too much!

Ehh, I know you're gonna get flamed for this one.
Let's just say that he knows more about tuning than 99% of the people here. I forgot what pro racing genre he works for, but he knows his stuff. as far as proof goes, his head alone has made 20+ WHP on many different 1.8L motors here. Most people spend about $3000 on mods that make way less than that (as you know doubt know). Not only that, but when he supercharged his Porche, Porshe wanted to inspect it themselves because they supposedly liked the results (or something to that effect; This is only the word though). I'm not on anybody's side, I'm just setting up the people that are going to go into detail.
In your defense though, some people are all up on his nuts like little Pussiiiies. I mean, it's ok to respect people, but to talk like he is Jesus is stupid. Ok, me go to bed now. -C

hahaha that's true

I read a lot about Endyn stuff at the Hostboard's F/I Integra forum, and from what I've read about him and his stuff, I'd say the guy knows his ****. Read his site - http://www.theoldone.com - and you'll get an idea as to how far he takes tuning and research.. Nothing gets left untouched - fuel, air, compression, you name it. Also, his stuff is geared towards the grassroots enthusiast, and priced accordingly.

The negative?

I recently blew two pistons, and was thinking of going to Endyn forged pistons, rods, and possibly some fuel pump / fuel system upgrades. I emailed "staff@theoldone.com" once to ask for advice on their pistons, and then again to ask for ordering information for a fuel pump. After receiving no response for two weeks, I ordered a Walbro from Jackson racing. I'm a computer geek, and I love driving fast, and I love cars. Unfortunately, I'm not a gearhead, and I don't spend as much time as I'd like working on my car, which is why I asked for opinions from the Endyn camp. Getting no response from my inquiries was disheartening.

I've attached the Endyn history listed on the old one site. From it you will see that he was doing this stuff before 95% of use were wearing diapers. People that use his heads and parts are very happy. If you don't want to use them - don't. As for getting back to our emails, Larry is extremely busy. The Honda stuff is not his main business as many may think. It would be hard to sell his pistons at $410 and stay in business. He is involved in more racing series then you could imagine. This weekend when we are watching the Indy 500 and Coca Cola 600, just think he's probably got a few engines running on the ovals. I'm not sure but I don't think their are any of us on this board that can say the same. Remember the old saying, "Good things come to those who wait".

Endyn Milestones

1959 - 65 Studied two stroke technologies. Built and raced karts nationally while developing and marketing increased efficiency engines. Engine modifications included revised intake and exhaust port timing and cross sectional areas, additional intake and exhaust ports, revised combustion chamber / piston configurations, crankshaft rotation enhanced ram intake induction, and variable ignition timing (load dependent.) Production of 43.4 BHP @ 21,000 RPM from 100 cc normally aspirated production based two stroke engines.

1963 - 65 Began initial studies of four stroke engines and modifications necessary to increase efficiency and performance.

1965 Designed and built a prototype compound turbocharged / two stroke test engine (non oil burning). 100 cc produced 121 BHP @ 20,000 RPM on methanol fuel.

1966 Began testing four stroke technologies and theory on a Ford Mustang with a 289 CID engine.

1967 Modified Mustang (street driven) set four quarter mile world records and won the AHRA Super Stock Eliminator World Championship

1968 Initiated in depth studies of chassis dynamics, torque reactive suspensions, and "ground effects". Engine geometric relationships and their relationships with cylinder head, camshaft design, and manifold configurations were brought to the forefront. Incorporate PROD (Performance Research Omni Development)

1969 Constructed Ford BOSS 429 Mustang A/FX S/S Eliminator race car. Set 13 world records in two weeks in competition. Developed the first plenum ram intake manifolds for BOSS 429engines. Chassis and body used advanced materials and high stress engineering technologies.

1970 Received sponsorship from Ford for continued development of cylinder heads, pistons, manifolds, etc. for the BOSS 429 engine.

1971 Studied fluid dynamics and began designing the first flow bench that would allow static evaluation and pulsing flow evaluation of cylinder heads, manifolds, fuel systems, and exhaust systems. The flow bench eliminated the need to build engines to specifically test modifications. Pro Stock programs first recipients of technology.

1972 Completed design and construction of pulsing flow bench, dyno facility, reverse dyno (testing pumping and mechanical losses), and performed all initial evaluation studies to link the data from each system into functional operating procedures. Programs included Pro Stock, nitro dragsters, funny cars, sprint cars, NASCAR, CAN AM, and SCCA.

1973 Formally opened ENDYN INC. (ENERGY DYNAMICS, INC.) to expressly design, modify, and to evaluate cylinder heads, manifolds, Pistons, exhaust, and camshaft combinations for sale to consumers.

1975 - 79 ENDYN initiates fast burn technologies. ENDYN performs all research and development for Penske Racing. Immediate results on NASCAR Ford V-8 include "fastest car in NASCAR", with a 25% increase in observed and "transient" power and a simultaneous 65% gain in fuel efficiency.

ENDYN leases engineering and shop space and performs all air flow testing, manifold design, and fabrication on the General Dynamics sonic, computer controlled Electrosonic X engine control system. handled all emissions testing required for system evaluation. Designed single plane 4bbl.competition intake manifold for Buick. Manifold is still available through Holley / Weiand Industries (PN 7542).

Conducted initial lean burn, high compression-bias combustion, swirl compression / combustion, high cylinder swirl intake induction experiments with promising results.

ENDYN modified Cosworth, including heads and manifolding win INDY 500 for Penske Racing.

1979 - 83 Continued "secret" experiments with both spark ignited diesel and multi-fueled internal combustion engines. Successfully adapted these technologies to "production" oriented engines (domestic and foreign). ENDYN receives Secret and TS security approval for Advanced Programs.

1983 - 84 ENDYN continues defense and government related secret programs.

ENDYN commits to advanced Pro Stock program, designing and constructing chassis, Aero bodywork, engine and drive train. Notable advances were asymmetric pyramid chassis with low polar moments, first Super Swirl engine, and first true ground effects full bodied drag car.

ENDYN pioneers CAD/CAM technologies in chamber and port finishing manufacturing techniques.

ENDYN unleashes portions of high swirl, high compression, lean burn technology. ENDYN swirl engines dominate 1985 Daytona 500 with track records and overall win. Dominating victories at 1985 NHRA WinterNationals. Convincing and unprecedented victories and world records during the remainder of the season.

The "Soft Head" era was born, with coverage by Hot Rod Magazine, Circle Track, CBS Sports, and ESPN.

1984 - 1987 Developments:
1. Swirl Combustion
2. Swirl inducing inlet ports
3. Sonic exhaust ports
4. Formulas developed for design of the above (1-3)
5. Utilization of ultra high (up to 23+ to 1) compression ratios without detonation with spark ignited gasoline engines
6. "Soft Head" combinations utilize (no's 1-5)
7. First to map cylinder pressure profiles relative to crankshaft angle at real world RPM and alter the curves as needed
8. Invention of multiple (3-4) camshaft lobes acting directly on inlet valves
9. Development of variable cross section and velocity inlet ports and manifold runners
10. Utilization of "reed" inlet valves on four stroke engines.
11. Achieve 4.4 BHP / cubic inch at "low" BSFC in normally aspirated endurance engine for O.E. manufacturer
12. Offset piston / crankcase / cylinder combinations for production based engines. Improved rotating geometry efficiency (i.e., longer cylinder and bearing life, and improved utilization of combustion pressure.)
13. Designed the following cylinder heads for Ford Motorsports: 302 SVO Cylinder Head (PN M-6049-D302)
- 429 SVO Cylinder Head ( PN M-6049-A460)
- BOSS 429 Super Swirl Cylinder Head (PN M-6049-A443)
14. Design of cylinder head, piston, camshaft, and intake manifold for Harley Davidson. Components now marketed by Edelbrock

1987 Major sale of limited combustion technologies to OE Japanese manufacturer.

ENDYN severs all connections to both public and media. Continued development of multi fuel combustion. Racing related programs limited to "select" teams.

1989 - 91 First experiments with modified Honda production applications.

Revolutionize camshaft design with "short" events and less lift.

Participation in World Championship motorcycle racing efforts.

1991 - 93 Supersonic combustion studies with "shape dictated" burn propagation.

Design and oversee production of heads, manifolds, bottom end for OE.

Sponsored Pro Stock effort. Winner of 2 World Championships.

1992 - 97 Combustion and mixture preparation are primary programs.

Continued manufacture of racing components. Studies of "new" forms of rapid prototyping, manufacturing technologies continue to keep ENDYN on the leading edge of engineering and production capabilities.

Honda programs begin to "influence" ENDYN's agenda.

1997 - 99 Rapid expansion of all technology fronts due to market demand.

Racing R&E continues to dominate schedules.

Manufacturing capabilities expansion to handle increased demand from all markets including Honda related components.

Proposal to go "public" with technology related articles is rejected. Plan to integrate technical papers into Honda programs is adopted.

ENDYN commits to many "Honda only" programs.

Just how does work they do for nascar translate into anything good for Hondas? There's nothing even similar between the engines. Our Hondas are so superior in every way it's not even funny.
The information and tips they post on their web site has caused almost everyone to damage their engines. I even think their pistons and rods are reconditioned used parts. Why else would they polish them? It's to hide the wear and combuistin marks.
Everyone should stay away from their web site and teach them a lesson.

bruthaboost

Hmm...I emailed the staff and received a response the next day. I ordered pistons, rings, rods, and girdle. I didn't ask for advice, just the products. I spoke with Mr. Widmer over the phone. Very nice person and no my nose wasn't up his ***.

Did you read this after you typed it?? What an ignorant statement to make. I suppose your Honda engine does not have a crankshaft, connecting rods, pistons...

Good engine design is good engine design... While a pushrod V8 and an overhead cam I4 aren't the most related engines in the world, theories will carry across the two.

Tanner

What are you talking about Nascar who said anything about Nascar and also you are talking about stuff you obviously have no clue about so I wouldnt talk too much......

Everybody knows that all they do is Nascar and the honda stuff is just a stepchild at best.
So what if both engines have crankshafts. They haven't been working with Hondas long enough to know anything about them. That's why shops like Atomic are starting to make their own "good" engine parts like pistins & rods. They even have heads better than Endyn too.

FAST94GSR

kilowatt you must be kidding. larry has been working on engines longer than you have been alive. FYI Atomic uses ENDYN heads and blocks. You don't know what you're talking about..

green_GSR

??? Honda engines are superior in what way?? If you're going to bash on Nascar engines, at least put some effort in explaing why Honda engines are that much "superior" than Nascar's. I hope you're not one of those riceboys who think they're driving a "godly" and "bulletproof" Honda motor.

Whose tips caused people to damage their engines? How? I hope you didn't do what Larry said when he was being sarcastic in his posts because some moron was posting a stupid question... but it seems to me that you did.

The fact is, you don't know anything about engines. It's sad, but it's true. You're nothing but a riceboy... like everyone of them, they put parts in their cars because the parts "look" fast and they "look" like they're going to make some whopping power. Let me quickly give you an excerpt of why ENDYN MACHINE their pistons.

Notice the carefully shaped dome configuration that's been developed using the extensive computer modeling, flow bench validation, and dyno testing. There are no sharp, faceted angles, or intersects to interfere with mixture travel or flame motion.

Think about those sharp edges on other brands of pistons and consider the fact that the piston is the floor of the combustion chamber. Don't cylinder head specialists remove sharp edges from the combustion chamber? Then, why would you use a piston that negates of all that chamber smoothing?

You better thank me because you've just learned something today. The fact that you can't even distinguish the difference between "Machining" and "Polish" makes me feel that you're not even qualify to spread you hate against ENDYN.

um kilowatt,jeff from atomic works for endyn you cack!

anyhow i know larry knows his stuff, and i know hondas arent his main source of income but i must add imo i think he acts like a grumpy a-hole at times. hes never ripped into me on his board but ive seen him say some rude shitt to people on there. thats not cool at all,even if he thinks they are dumb questions thats uncalled for,not everyone comes out of the womb with a degree in physics,chemistry or is a master mechanic.

in short fukk larry, hes not the "only" engine tuner/builder and hes certainly not the best.
NO FLAMES EITHER, remember this is an open forum and i am entitled to my own opinion.

bigTom

i still stand on my opinion... 2 many people (to be blunt) ride his dick like he is the god of honda... he's nothing in the honda world... he makes a fast car... tell's everyone all his "little secrets" any builder that makes a fast car will not tell their secrets... im not personnally gonna listen to some guy in bumblef*ck nebraska telling me how to go fast... and if anyone here trusts his history so much... y dont u bring your car down to the mustang guys... afterall... many of the builders have 9 second cars... AND they may have been doing it for years... AND they know a shitload about motors... still doesnt mean i would trust them with my motor...

im not about to trust my motor to someone who doesnt deal strictly with my motor... thats how i feel... everyone also says larry's such a good guy/nice guy... hey... call me up... send me money for parts and ill be the nicest guy the world... notice many times people complain when they email him a question they get no responce... but when they want to buy something they do???

bigTom

i second that... there are some engine builders around my way that i trust... who is larry???? just some online guy that gives kids advice that dont know anyone better to go to

FAST94GSR

Jeff does not work for ENDYN, he works for his own shop. He deals with ENDYN. FYI Jeff is in California, ENDYN is in Texas, that is quite a commute to to to work..

4dgsr go read HOTROD mag, he has been posting articles in there for years..

Larry is a NASA engineer. He can go so far as break down the metallurgy in the parts he uses.. Yea anybody but can build fast hondas nowadays. Larry knows how to make anything fast and has been for over 4 decades domestic before import.
I think you should get more information before you dig yourself a deeper hole. Why don't you read his website. http://www.too.com

O ya he's rude sometimes but after 50+ years of dealing with young kids that ask the same ole questions, you'd be the same too.

radiac

i don't know larry personally, but i can completely understand the purpose behind his strict policy on HIS board (it is HIS board, after all). he obviously wants to reserve it for truely technical content, and there's absolutely nothing wrong with that. if you've ever browsed the posts, for every time he's ripped into some stupid riceboy for asking how install his altezza tailights, he's offered truely valuable information ten times over, at no charge what-so-ever, i might add. i can't say much about people "riding his dick," as someone kindly put it because i haven't been around long, but i can say this, my respect is given where my respect is due, and it goes to larry--i've kept a keen eye on his board and what he says for long enough to KNOW that he knows what he's talking about (not to mention his results, a 480+ hp d-series).

4dr GSR,

Im just kinda wondering why you decided to post it they way you did in the first place? I can see questioning ENDYN but your post seemed more like you or someone around you is either jealous or for some reason have agression towards ENDYN for whatever reason.

I dont know much about it, I just know its from where im from and theyve been trying to get this SC thing finalized forever. I do know their test car is powerful as fvck and their product (if it ever is officially released) will blow any other SC for an import and most Turbo's out the water. But does this mean im riding their nuts? I never say Endyn this or Endyn that,..but when thinking about SC's for our Honda's/Acura's, Endyn is always in the back of my head because I want to see just whats really going to happen.

And as far as people emailing them and getting crappy service,..ENDYN is not a major corporation or even a company that has 30 employee's. From what I understand, its just a very small handfull of people working out of a shop they call their research lab (no disrespect). This is why they need your car for 4-6weeks or however long it takes to do an ENDYN upgrade to an already JRSC'd equipped car. If you want someone that knows the way ENDYN runs their business, let me know and I can get that person for you.

green_GSR

The fact that he builds a 10 sec D16 Honda Civic daily driver with full interior running on pump gas does make you think that he knows how to go fast and certainly knows all about Honda engines. You're comparing Larry's Civic with the Mustangs, but what are you trying to prove? I can tell you that the domestic's Larry built decades ago can still smoke the Mustang boys without a problem. You see, you have to compare apples to apples...so you have to show that there is a person out there who can build a daily driven 10sec D16 Honda Civic that is as fast if not faster than Larry's Civic.

And no, I never bought any parts from Larry, but I still get free information in how to build up my motor, so I don't understand why you people hate ENDYN so much. It's not like Larry is putting a gun to your head and tell you have to build your motor this way. If you don't like his philosophy, then don't follow it. Simple as that.

You know what's ridiculous. This topic got five stars. It gives you background on ENDYN, but other than that this post provides very little useful information. I agree with green_GSR. If you don't like his ways, don't listen to him.

I'll bet the only thing that the civic smokes is it's exhaust pipe. Most of my friends take the tips from the endyn board, reverse them and then they work OK. The only one at Atomic that knows anything is Charles, so anybody else you talk about doesn't know crap. He's been around hondas since the beginning.
