GSE980

SO I went and got my GSR tuned on 15psi the block is fully built with only a valve job and P&P done.

The tuner said because my pistons are only 8:5:1 that its hurting me for horsepower.....

The car made 279whp
242lbs. of torque

My goal is to hit 300 just wondering what it will take to get there??

bigger injectors and more boost

What is your setup? What size is your turbo?

thats very low for 15 lbs... you must have a terribly small or inneficient turbo... and 8.5 CR is very low.... you should bump to 9.0+

intense4thgen

install tunner 1's and retune with gears

boostedcivicsir

to play devils advocate, many are making great power with stock cams, i made over 500 on a bb16 with gsr's. granted that was 28 psi with 1200's on a t3t67ho.

there isnt enough information from the o.p. to properly diag why the power is low.

we need injector and turbo size atleast.

goin back to my old setup, t3t04b drag kit, with 750's made 330 with a slipping clutch. 8.8:1 compression.

Rev it higher

Need to know the following before anyone can give you any real advice:
-what turbo
-what intake manifold/tb
-turbo mani
-who did your head work
-exhaust size
-post your dyno sheet

But judging by the numbers you posted, I'm inclined to say you have a turbo that's on the small side with a restrictive exhaust.

mill the head .040 and have fun

That is super low power, probably the lowest per psi i have seen out of a B so something isn't right, that compression isn't that bad. Give us all the information that was asked for. Your full setup, dyno sheets, what engine management??

Colby71

just turn the boost up a little you only need 20hp to hit the 300hp. The turbo must be small and spool quick to make 242tq.

boostedcivicsir

thats not the smartest thing to do if he is out of fuel.
making assumptions at the expense of his engine isnt a good idea.

On a side note, did you enjoy Bahrain last week?

intense4thgen

Your 100% about the lack of info. Also i just though id throw out the cams idea as it would easily push him past his goals with out adding more boost.

YARO.

More info is needed!! That power is very low.

-what turbo t3/t4 turbonetics hybrid BB
-what intake manifold/tb stock/stock
-turbo mani log manifold
-who did your head work accurate automotive machinejust a 3 angle valve job
-exhaust size 2.5 greddy evo4 welded the test pipe myself
-post your dyno sheet sorry dont have it on file

also I have 800cc DSM injectors

BAHRAIN IS AWESOME......!!!

i would do a full 3 in exhaust man you would be surprised how bad it would open your car up

well your exhaust is not your problem ive made well over 500 hp on a 2.5" exhaust many times
i see nothing that is holding back your power maybe your tuner?
ive made 300+ on a gsr
bone stock gsr 880's precision sc34 on 8psi put down 301whp

GSE980

my tuner was shawn church... so I dont think it was the tuner he did say he was getting inacurate readings from the A/F meter he was using like a exhaust leak..... and had to use my in-car innovative wideband ....IDK

YARO.

Yeah def something wrong there. What are the specs on the turbo? (t3/t4 is not enough) even with the low comp is very low on power. What cams and whats redline?
I made 340whp on a stock gsr at 10.5 psi.

GSE980

stock cams with the stock redlin....... its a 60.trim that all I know about the turbo

blinx9900

t3/t4 huh, geez, so much detail... what t3/t4 exactly do you have? If it's a t3/t04b thats normal power, compression has nothing to do with it, i made 333whp with a GT3076R at 12psi with 8.3 compression on a b16.

Your exhaust is small too, your log manifold isnt helping either.

inspector01

That is not normal for a t3/t04b, something is legitimately wrong with it. I agree compression isn't the problem, but a GSR should easily be making 10+whp per psi, most make about 15 depending on the setup, he is at about 9.

Did you guys try dynoing at a lower boost to see if it was just a problem up high?? I would start as low as you can and work up until you see when it stops dropping power per psi.

d112crzy

What sort of dyno was it? I wouldn't worry about the peak numbers as much as the shape of the graph. Without the graph, we can't really tell you where you're going wrong.

JDogg

if it was churches dyno then that power is WAAAYYY low.
