Woody.

I'm about to JRSC my motor once I finish building it, and then I will be taking it to get tuned. I've read and seen higher SC boost (8-10+ psi) create high high intake temps and cause detonation. Ive also read that tuning on a standalone greatly reduces the risk of detonation. Of course the intercooler will be better, but will the heat exchange suffice? I live in Texas and summer temps can reach 110+.

My setup:
AEBS sleeved ITR at 84mm.
LS crank
Manley Turbo Tuff Rods
Wiseco Pistons (~11.0:1 Compression)
New OEM ITR Water pump, Oil pump, Timing belt, seals and gaskets
Balanced rotating assembly
B16 head
ITR Cams (May upgrade to s2t2) with Skunk2 Pro cam gears
Supertech Valvetrain
3 angle valve job and intake/exhaust port
Hondata IM Gasket
AEM Fuel rail/FPR
ITR header with 2.5" hytech catback.
JRSC With 10 PSI pulley
Fluidyne Radiator with FAL shroud
A/C will be retained (its 110+ sometimes, and rarely falls below 98 from May - August) FAL shroud on the Condensor as well.
Will be tuned on Hondata s300 (Partial and full throttle)

Running 10 PSI will i run into detonation problems?
Should I run less boost?
I'm shooting for around the ~250 WHP range and would like to make good numbers when i do go to the track.
Will the LHT heat exchanger suffice at lower my intake temps? Or am I going to have to run the intercooler setup?

Also - Ive read some stuff about a boost controller on a supercharger. Does anyone have experience with this or know how it works?

Let me know if i missed anything or if I wasn't clear enough.

Woody.

No one?

LHT should keep your air temps down. I run 11psi on my jackson/lht set up and my air temps are lower than a n/a car. It all comes down to the tuning.

Woody.

Will be tuned by Tony at T1 Race Development. Will the heat exchange suffice or do i need to get the intercooler setup?

I'm not sure I understand your question. The LHT setup "IS" an aftercooler. The heat exchanger is a part of the aftercooler setup. They have a std. and a high capacity heat exchanger setup. I would suggest that with your summer time ambient temperatures, that the high capacity (upgraded) heat exchanger setup is the one you want to go with the LHT aftercooler installation.

The only boost controller I've ever heard of for the JRSC setups was made in very small numbers by a guy several years ago, and all it did was electronically monitor the boost pressures, and opened and closed the bypass valve based on what you wanted for boost pressure. I don't know if you could even get your hands on one anymore, and I'm also unsure on how effective it was.

Woody.

LHT offeres two setups. One is $1000 that includes work to the manifold and the water to air in the manifold, and the other is simply the heat exchanger with no work done to the manifold that costs ~$400. Am i understanding that correctly?

As far as the boost controller, i read somewhere that you could install a high psi pulley (20 for example) and use the boost controller to DROP the psi to say 6 when DD.

Woody.

Or do both kits require work done to the manifold... just the higher price one has porting work done?

Jaker

To gain any benefit from the LHT cooling, you absolutely require the manifold modifications. There's no getting around it. The difference is that the base kit comes with a std capacity heat exchanger used for regular daily driving and the odd trip out to the drags, etc... The high capacity upgraded heat exchanger is used for locations that have high daily ambient temperatures, or where you're using the car in situations where you'll be boosting for extended periods of time (like road racing).

They both come with porting of the S tube and the intake manifold. That's part of the regular pricing of the kit.

** edit ** I had that all wrong. The basic intercooler (aftercooler) kit is $895, and then you HAVE to buy (or supply your own) heat exchanger kit. The STD heat exchanger kit from LHT is $495, and they also have a race version which is probably more expensive, but no price shown on the site. So in reality, the LHT aftercooler setup, if you bought it all from LHT is $1,390. you can piece together a heat exchanger setup for much less than that if you go shopping around.

There is no easy way of controlling boost on a JRSC supercharger, other than changing pulleys. You can go to a smaller supercharger pulley, a larger crank pulley, or a stepped alternator pulley. It's not like a turbo where you can bolt a wastegate onto your charge piping.

Woody.

So what all do I need to make my own heat exchange kit? I hear of people using the 03-04 SVT setup. But what would I need to do my own.

Jaker

You need to do some research and interweb searching.

Woody.

I have done tons. I have't found any write ups or FAQs or anything about it. I even read in the JRSC thread but didnt really find any answers to to it. Most of the threads are people posting with no replies or people bumping for the same info.

Got any links or anything?

JDMThoughts

I can tell you right off the bat that those cams need to go. You need GSR intake ITR exhaust.

C_Rock77

Lots of people get old Mustang Cobra Heat exchangers. LHT's is a modified FMIC for a turbo that runs water through it.

Woody.

Whats a good compression ratio to use then. And what cams would you suggest other than the gsr/itr combo?

Next, is the LHT a must or can I get my car tuned and running prior and then retune it. I'm currently without a car because this is going on my daily and i'm completely rebuilding my motor.

Edit:
Also so the ~$900 LHT Kit INCLUDES the heat exchange? If not, what all do I need to make my own. I will be using a fluidyne replacement for a cobra SVT if it doesn't.

Why not just turbo the darn car, you built the crap out of the engine and heat wont be an issue. I never understood why anyone wants to S/C a honda. Here comes the flames LOL

Woody.

Because in my opinion a turbo'd honda is like a high maintence woman. And I don't need two of those in my life.

boca

agreed^^

if u were stock and wanting just a little more power with out headaches then yea s/c..

but in your case your car needs a turbo....BAD!...lol

boca

my car has been turbo'd now for 3 years from LHT performance....and i never done anything except change oil and spark plugs....

Woody.

Supercharge is instant power though. Turbo has a lag. Plus i already have a JRSC

An improperly tuned/built any make car is like that IMO done right shouldnt give you a single problem and will make ALOT more power.

Ive been running piston/rod stroked gsr for several years now at 400hp without a single issue that wasnt my own fault, aka being lazy and not changing out the clutch master so started to grind gears. otherwise motors been rock solid, no oil leaks not problems at all

S/c isnt instant max boost it comes on with rpm same with a turbo and the s/c robs power from the engine to spin it vs turbo doesnt rob any power and a properly sized turbocharger wil spool very quickly and net alot more power than a s/c But being you have the s/c already i understand sticking with it. Def need that aftercooler and i would personally run meth injection in the summer in Texas with a s/c. Otherwise Tony knows his stuff and will make it work well fo ryou

Woody.

I'll talk to Tony about the meth kit. If I can get a legit turbo kit for my JRSC I'd be willing to trade, but every turbo i've bought off Here have been rebuilt or "new" with more play than Pamela Anderson's vag.

Woody.

Turbo was my original plan for the car but everytime i start buying the kit on here something is always wrong with something I buy. So I gave up on that. This isn't a track warrior its gonna be my daily. Which is why I went with a JRSC and I had a friend with a JRSC and it ran about the same time as a 450 HP turbo civic. Also wouldn't I have more problems with my compression ratio on a turbo?

C_Rock77

What do you HAVE as far as parts go?

Is the block you discussed already built? Manley's are great, but they're like $700+ per set.

CR: I'd go with slightly lower, around 10:1. It was what was suggested to me by Tony and RMcDaniels.

what's your email? I'll forward you something John from LHT sent me.

Read this thread https://honda-tech.com/forums/forced-induction-16/endyn-ported-jrsc-%7E12-lbs-lht-intercooled-what-cr-should-i-shoot-2557115/

Let's get back on topic. This doesn't need to turn into a JRSC vs. Turbo debate!

Woody.

I have everything listed. Motor isn't built yet. I was gonna wait to build it until after I sent the JRSC off... ill pm you my email.

JDMThoughts

The GSR ITR combo is one of the best setups you can use cam wise.... IIRC Jon@LHT I think had specs on custom cams to make even more power.
