motor B18c1. bored .20 over JE pistons 9-1 compression Eagle rods. rocket valve springs and retainers, A.E.B.S. intake manifold, CTR cam-exhaust side, aem fuel rail, precision 880cc injectors, ss autochrome tubular exhaust manifold, turbonetics hybrid t3/t4 turbo tial 38mm wastegate, 2.5 inch down pipe 2.25 inch exhaust-no cat with a 2.25 to 3.5 top speed muffler, greddy intercooler (rather small piping) turbo-xs blow off valve. tuned with a hondata s200 running 15psi. I dynoed at 308whp and 206 torque at 9,000rpm.

everyone thinks I should have more hp. comments?

 

You've done more than a lot of people on this site, why are you asking a question like this?

That's quite a setup you have there. The ss autochrome and xs stuff, I'm a little wary about for you there, but if they work well...

I don't know what to tell you, you're running some good horsepower already, but if it's getting to you this badly, go talk to your tuner about it, and schedule some more dyno time. Maybe they tuned for a more even power curve, rather than one tuned for high hp numbers. I don't really know what to say, there's so many variables, but I would say the only thing you could do without going more aggressive on the hardware, would be to retune and cross your fingers.

 

thanks! I don't know too much about tuning. I am more of an enthusiast than a mechanic, but I do remember the tuner trying a couple of times to get a more even power band.

 

I think you should know that a super peaky powerband would be increasingly difficult to drive, but if it's not your DD, then whatever. You should look around the Forced Induction forum as well for some better answers.

 

t3/t4 tells us nothing. you could pick up a few hp by changing to a bigger downpipe and exhaust.

 

2.25" exhaust = you're not serious at ALL about making any power Get 3" straight back from the hot side, including the downpipe and get a log manifold. I guarantee you'll pick up a lot of midrange and a ton of top end. What's the A/R on your turbo housings?

My friend with a bone-stock GSR with a BLOX intake manifold and a log at 9psi is making 283hp at the wheels. You're running 66% more boost and making 10% more power. That should tell you something.
