Has anyone gone through Endyn for parts, engine building, and head porting? I've only read their website and it sounds like 300HP on a 2.0L N/A motor is not very hard the do. I will appreciate any good or bad comment on this subject.

I've seen the pistons, and Larry's kaa... both are badassessessess But then if there is someone who can pimp power outta a 4 cyl... I'm happy!

I'm running their pistons and head.I'm really happy with it

i'm running a set of his rollerwave pistons, and love them

my gsr head has been p/p and they did all the milling and my 5 angle, they did a beatiful job, the even put these little indentions on the intake side to help atomise the fuel as is shoots in. enyne getsa from me..

I've built a lot of motors with endyn parts and portwork on the head, all are very impressive ... I used to also try different pistons like JE, Arias, etc. none compare to the quality of rollerwaves. Headwork is very impressive, I was able to pull a lot of torque output from Endyn heads period.

Their valvesprings clear the highest lift camshafts i know of and I rev those cams to 11.5K rpm without a problem. Their retianers take a beating and are very durable. Breather kit gets the job done.

I think it is very cool that larry takes alot of time out of his day to post on here and his web board. time is money, and he is loosing money or dyno/R&D time he could otherwise be doing instead he is helping people out.

im guessing because he loves what he does. its cool he hasnt sold out, or changed the core nature of his business for a while. that says alot that he is in it for making fast cars and helping people out vs just making money.

afaik all his products kick *** and he knows hondas alot. what else could u ask for?

HEAD

I don't know Larry very well but from the short time I have been around him I will say that this is a man who is in love with his work, although I haven't had the opportunity to see any of his work I am sure his love and pride reflect in his work meaning you won't get something that is just enough to get buy, you will get something that is well thought out and well executed. He is also very giving in his knowledge which shows me he is not only a very smart man but a guru.

That was really cool of the both of you to say that. I do know that Brad and Larry talk some. Good sportmanship.

I doubt that they will hit 300whp. That thing doesn't even have a deckplate and they're planning to rev to 10k with a stock sleeve. I think they have already broken in the motor and dynoed it but afraid to post the graph. Someone correct me if I'm wrong!

Maybe, maybe not. Although this is the same guy that made almost 500hp from a SOHC 1.5L and drove it practicaly every day.

it just takes money to get there.

fox297

I have no doubt that with enough money, one can built a 300whp 2.0L n/a engine with ease. However, with the current bottom end setup that TOO is having, I'm not supprise if the sleeve will crack before they even see 300whp. Remember, it's an open block deck with a 1.54 R/S and they're talking about 10k rpm.

I've have a set of their rollerwave pistons in my setup and I definitely have no complaints, and Larry definitely knows his ****.

(re)read the 'bad to the bone' article.

by using +.137" LS-length rods, and pistons with the wrist pins up +.137", Larry has achieved a 1.58:1 R/S ratio (same as B18C) using the 89mm (LS) crank for the extra ~40cc, less friction (sideloading) than a 1.54:1 r/s (the skirt coatings help, too), and the ability to have the engine breath easier at higher rpm (better geometry promotes better cylinder filling).

now, he also has his new CF intake manifold on it, which is purpose-built, plus the equivalently built HiTech header, and the head, which he configured to run just on the safe side of the fine line between optimum performance and self-destruction; ~12.7mm cam lift, and relatively long duration (especially for oversized valves), operating at or above an rpm (&gt;10K) where many folks float valves.

it's not blind luck or skill at plugging in good 'shelf' parts that makes ~150hp/litre. the parts just won't work so well together. Larry knows how to tweak and reconfigure/re-engineer them to make them work well together, and i suspect that he's gotten the configuration to the point where the head just can't flow any better to support any more rpm or displacement to make power meaningful enough to help the car run any faster.

What cams is he running now? Wasn't he using JUN 3's at first with only like 12.1mm of lift?

BTW, good explanation.

slofu

i think that he said that he runs his own grinds now, which are similar to the Jun 3 profiles, but wilder. (i think Skunk2 stg 3s have ~12.7mm lift, too; he might even have to mod the LMAs to accomodate- not sure.) he also modded the radii on his rocker pads to work better with them; further proof that 300 na whp from a street b-series combo is far from 'plug 'n' play'.

he might be able to eek out more power if he ran race fuel and raised the compression. he said that the pistons which he used weren't even ideal; the valve reliefs were a bit off, as they were development pieces from another project. still, i doubt that for his combo, the head can be much improved.

for all of the b.s. associated, i wouldn't blame him if he never posted a graph. enough people use and like his products, and he gets enough 'free' advertising and web-hype ('no such thing as negative press', right?) that he doesn't seem to be hurting for business.

fox297

Incase you haven't read the article, the pistons retain stock wrist pin location, so it is still 1.54 R/S ratio. I don't know if this is just a fun experiment to test out the block, but I would not spend all that money developing a 300whp on a stock b20 sleeve. Someone please correct me.

methred_92

Just for the record. The sleeves are posted and are *modified* stock sleeves.

Endyn has nice pistons.

But they're is plenty of hype. I've been waiting for their supercharger to come out since I was an 18 year old in highschool, and now here i am graduating college, and it still isn't out... lololol.. plus i remember a while back, there were a few scandals about people who spent alot of money with larry only to get their cars come back to them with less whp, and tons of problems.

When you listen to Larry speak, he's so knowledgeable, he speaks so eloquently about engine dynamics that he overhypes himself. With the knowledge he seems to have, you'd expect him to bring out some serious cars out of his shop. Like 1000whp turbo hondas and the like..but i've yet to see anything impressive come out of the shop.

My opinion on endyn is half/half...i really don't know what to think about them. Good pistons though, I have friends who have made good power on them!

specie

Endyn/Wiseco pistons are nice. If you need pistons, can't go wrong with them. The man seems very knowledgeable and I won't lie, his theories are way over my head. However, I've read that there were some problems running his "shop" back then.

300whp on a B-series NA setup is kind of hard to believe, since I don't think any race team "with lots of sponsorship $$$ for research has accomplished this on a B-series yet. Although I think Bisi has made a little over 300 with a F-series.

slofu

from the article: 'We’ll take one of the rods we plan to use (in this case some standard issue Eagle units which are .137” longer than stock'

#1 Rod:Stroke ratio is exactly that; it has nothing to do with pistons.

#2 You cannot use rods which are .137" longer than stock, and pistons with pins in the stock locations without a deckplate, or the piston domes will hit the head (which he said that he milled for yet more compression).

SMSP

I think we are all just waiting to see a dyno sheet of just one of the "in house" built Endyn engines. I haven't seen one in 4 years yet. Back in Jan we were told that after the 1000 mile break in period he'd post the dyno of the new B20, then he said he didn't have the time to go to the dyno, then he said he wanted to use his new intake manifold before the dyno. Still no dyno graphs.

Obviously Larry knows his stuff, I just wonder why he's so afriad to post a graph of just one of the engine's he's built? Maybe he's waiting for the best "I told you so" time, but then again...

250whp isn't too hard to make from a 85mm x 89mm B20VTEC. 300whp on the other hand is alot more work from the same bore and stroke. I think Eric once posted some 304whp dyno sheet but that engine is no more and his times of 10.50 last weekend tell us his new engine isn't there yet. But I'm sure it's just a matter of time until Eric is in the 9s again.

You should also look at the IB Spec pistons, I think they are cheaper also.
