ok here is a pic of my dyno tuning i just had done, Greddy TT, 650cc inj. a little lower than i would like to have at 8psi but it's still fun to drive. this is a stock motor with single
3" custom exhaust tuned with a u-tec on 91. so what do you guys think?? i was hoping more for 400/400. A/F ratio is solid though

 

you wont get there at those psi levels with a single exhaust

what about test pipes?

 

i have straight through exhaust, test pipes and all. on 93 octane it was making 414 whp and 400 tq on 8 psi.

 

What's your A/F at redline? 11.5?

 

Bro! Thats great power at the psi level and 91 pump gas, with 93 and true duals 400 is no problem.

Dont be down...Thats good power.

 

Very good numbers. The single exhaust is the culprit.

 

it's a nice smooth delivery. maybe i need to save for an exhaust for that little extra powa

 

not too sure but it wherever it's at its even the entire way

 

sooo if that isnt so bad then why (this is just a ?) does someone locally have an aps tt kit with 416whp on 91?? and i'm only and 385?? my 94 rx7 with a single tuebo on the 1.3 litre had 390hp.

 

Different setups? Different Exhausts? Tuned for heat? Who knows?

 

+1 on that its great power still...but...i have seen 400s at that psi here in az at 91 on Dj uncorrected...all running strong.....all with safe a:f


actually the 3" single is enough for well over 400s

 

very smooth curve - nice!

 

Tough at 8 psi on a TT kit

Stop whining and enjoy the car, with a single exhaust system the turbos get bottled up as the rpm's go higher, your torque is fine as it is down low but your hp suffers as it is up high in the rpm range, you switch to a dual exhaust and the top end will free up and get that extra hp up top.

 

Looking good. For 8psi on 91 with a single exhaust - great power. Should be nice and "safe" for the stock block.

 

Kevin, You're tuning the same setup on a lower octane and making it safe. You know you weren't going to hit the same levels or expect it to barely change by doing that.

 

no, i know i was going to loose power but now in the top end 4-6th it just feels like it's holding back, almost like i only get 90% throttle instead of 100% throttle. it still feels good just not screaming like it use to on the top. i dont mean to sound like i'm complaining i really enjoy the car and your responses definately make me feel better

 

Those #'s were close to my TN kit and that at the time felt FAST to me, just enjoy your car man. IMO-not worth the money and hassle to swap exhausts, freshen up the tune, etc for 20 or so whp...

 

oh, that is a fresh tune.
