im currently running a stock b18c1 (healthy compression) w/

SC61
inline pro cast manifold
precision intercooler
2.5 charge pipes
aebs intake mani
650 cc injectors
neptune rtp
3 inch downpipe to exhaust

the car still has a/c and p/s and a recirculated dump tube

on 10psi the car only put out 270-275 whp on a dyno dynamics

i wanted the classic 300+ whp out of this set up but i didnt get it.. any ideas?

 

up the boost, or if you really only want a number try a dynojet?

 

You should be able to do that with the current setup, honestly. Time to look at the tuner, and check the type of fuel you're using, in addition to the amount of advanced timing is being performed with the tune.

SC61 is a BIG turbocharger, and has been known to do a lot CFM without much boost over what you're expecting.

 

I made 309 with less boost and we have about the same setup. I just have an Ebay turbo. But every motor is different. How much experience does you tuner have?

 

You would make more power without the recirculating dump tube but depends on if your up for that. 2 more psi wouldnt be too much more stress on the engine and would probably make a good amount more power with that turbo.

 

tuned by chris harris at xenocron

 

switching the wastegate dump to the atmosphere would pick up a bit of power.

 

methanol kit?

 

its a cool 70 out right now and it definitely pulled harder, my engine bay is an inferno when its 90 out, any metal part in the bay can burn you...

 

The first thing people do is blame the tuner.

 

The car is fine the dd just read low. My friend has a dd and i seen a stock gsr with 11psi on it make 305 and it was a egay set up on it. Car is fine just turn it up a little. My car made 518 on a dd and it traped 139.

 

This.

OP, how far does your dumptube go down into the downpipe before it terminates? Just curious. Me, I would just take it back to Chris turn up the boost a little on a retune until it reaches 300, or if you're happy with how it feels in cooler weather when your IAT's are down, roll with what you have.

 

it is flush and dosnt enter the downpipe.. i feel like i should make a cold air intake for the turbo.

343whp/249tq at 10psi....
so 270whp seems pretty low

 

Look at my sig. Different dyno will read different numbers. They don't call the dyno dynamic a heart breaker dyno for nothing.

 

word

 

i also have a slim fan right next to the air filter that is on 75% of the time blowing air around it.. is that an issue?

 

My comment was directed to "speak" with the tuner, not replace him, or place blame. Talk to him about what he performed, and why, learn about his "style" of tuning and if perhaps there were other elements that he may have not been aware of that may affect some parameters of the tune.

 

I say open dump under oil pan and hit up a dyno jet on 12 psi and you will see much better numbers

 

because thats usually the problem... that dudes car should easily hit 300whp... **** stock b18b1 motors easily hit 300 on about 15 pounds with alot smaller of a turbo... and not to be dick riding or anything but i wouldnt doubt TheShodan, 99.9% of the time he's dead on accurate.
