I just got off the phone with Kitty at Autolink motorworks, she said my car after tuning was a 175 whp. Does that seem low for this setup:

Stock b16a2
Drag Gen III kit
V-AFC
DSM 450cc
Apex'i WS cat-back - 2.25 inch piping

The ONLY thing I could think of is the 2.25 inch piping is keeping the turbo from spooling fast, so I am not reaching 7 psi by redline, because my autometer boost gauge says 5, but its an autometer, so i don know.

Would 2.25 inch piping hold back my HP numbers TAHT much? I thought drag kits on a b16a2 would make at LEAST, 200 whp. Thanks

bump for needed opinions...
is it true I could gain another 30 whp just by adding a 3" cat-back?

drvfast

yea the piping is killing the power, what was your a/f like?

you got the afc hack ? and what kinda dyno was this on?

Don't even worry about it dude...when I first had my car dynoed, I had a bone stock b18c1 with a revhard stage 2 kit. I too had a 2.25 inch exhaust and at 7 psi, I only managed 170 whp . After I got a 3 inch exhaust, injectors and the hondata tuned, I made 232 whp with 7 psi. Just get a 3 inch exhaust and the numbers will go up good luck

My old drag 3 kit b16a2 on a mustang dyno with Hondata, Tanabe RM(maybe at most 2.5") made like 190whp at 7psi. I did have no cat however.

I didn't have a problem hitting full boost by around 4k rpms though on t3/to4b.

Mr.DC2TurBo

Your exhaust will still let you reach 7psi or more so that can't be your problem. smaller pipping just make spool time longer.

Del_Slowest

smaller tubing makes the spool time longer? you mean the time for it to spool up? i thought smaller tubing made the turbo spool up faster?

my first pull @7psi, b16a with hondata was 261whp...was alittle lean though

Del_Slowest

So 175 whp on my setup would be reasonable then...since im running a 2.25 inch exhaust and stock cat? What other things could cause it to make less power? BOV leak? intercooler piping leak? Also, my gauge says im only boosting 5 psi, but my tial wastegate is set to 7 psi. is it possible to lose 1-2 psi through my intercooler?

Mr. Softee

5psi with 2.25" exhaust will definitely not make much power
