I think the people at Jackson Racing might be screwing with me. They've told me that other than what I already have, there's really nothing else I can do to my car to make more power. They said I could buy their VPAC, though. They say I could use that to lower the VTEC engagement point and gain some low-end torque.

Have I really reached the end of the line? Where can I go from here? They also told me that I'm at the limits of my tranny (which I've heard before, and I believe them), and gave me the number for a place in Cali. that specializes in Honda transmissions.

I'm gonna call the two Hondata dealers in Houson and see if Hondata is an option. Other than that, maybe alcohol injection?

With my setup, when am I going to have to start building up the internals?

 

uhh...you might want to start by telling us how much power you are making...how many psi....what type of fuel management, injectors etc...

Sorry about the lack of details.

Power= Unknown. According to JR it should be around 230.

psi= 7 lbs of boost at full throttle.

Fuel management= JR FPR and fuel pump that came with the kit

EMS= JR unit that came with the kit

 

upgrading to either AEM EMS or Hondata will give you greater tuning possibilities. Upgrading the stock pully for a 9psi one would give you more boost. New Injectors with the new management will allow more tuning possibility.

If you really want to risk it just for power, you can try to run nitrous direct port after the blower (might be difficult).

Are you running any type of header or exhaust? (diameter, brand, etc)

Running a vented hood will allow the jrsc to cool and you won't have the parasitic properities for power with heatsinking of the blower.

whoops didn't read your sig. I suggest dumping the DC and investing in the SMSP jrsc header and getting a better exhaust (larger diameter...mugen is more for NA) with either test pipe or high flow cat.

I called one of the Hondata places in Houston. They wanted over $300 per hour to dyno tune the Hondata... Which I was also told would net me very minimal gains.

I was thinking a direct port 50-shot from NX might be nice... would it be safe to use with my setup if I only used it 3-6 times? I'd only use it at the strip, and even then I wouldn't use it everytime, just if I was to compete in the Sport Compact event.

If I went direct port, would I need to invest in a new intake manifold?

Yeah, I'd like to dump the DC and get an SMSP. I've heard really good things about them.

Switching exhaust isn't an option. What if I ran larger diameter pipes and a test pipe from the header to the Mugen canister(or whatever you call it)?

Does anybody think JR's advice of buying their VPAC http://www.jacksonracing.com/S...33962 will really help?

If anyone is wondering why I'm looking for more power, it's because I got killed by an SRT-4 at the strip, and barely beat a GTi:

the JR unit isn't the best way to tune a car. it might be safe to run a little shot, i don't know if anyone on this board is using nitrous in conjunction with their blower. I have heard of someone teflon coating the blades of the SC by endyn and helping keep intake temps lower, but it costs like 2000 dollars. if you went direct port you would have to tap the plenums i believe and there's really little room to do that.

how large is the mugen canister?

Good question. I'll get a tape measure and check it out. BRB


EDIT: Damn, it's just over 3 1/4 inches. WTF do I do, go up to 4???

EDIT #2: That's the width at the opening on the tip, if that matters.

 

the exhaust tip size means nothing.


anyways...considering you haven't even dynoed how do you now you're even making the power you should? You have major fuel problems and not even know it.

Poor tuning on boosted applications can easily blow a prelude motor..don't let it be you. At least go get a baseline dyno done to see if you are making good power

 

hmm that should be free flowing enough. get 2.5" piping and run it to there.

 

get a better header or modify your DC
