GT35r 396whp on 93

Default Is this good power for this setup?

So here is the setup on the car I just bought (have not picked it up yet though). It made 396whp/359tq on a mustang dyno. It was on 91 octane and a 100 degree day at 24psi. Not sure on the a/f. The car has a meth kit on it, but was not used. Should this be of concern? Or is it possible to have these numbers and be somewhat safely without using meth?

My last question is my last sti made 347whp/349tq on a dynapack. How are these numbers in comparison? For example does the mustang read higher or lower than the dynapack? Thanks for your input.

Here is a list of mods:
-GT35R Ball Bearing Turbo Kit .63a/r 84 trim wheel
-Agency Power 3 Inch Catback Exhaust
-Tial 38mm wastgate
-Walbro Fuel Pump 255L/HR
-Power Enterprise 850CC Injectors
-Cosworth Pistons
-XS Engineering Front Mount
-Agency Power Crank Pulley
-Greddy Profec B2
-ecutek tune

i would hook that meth kit up for that much boost. seems like its a real low reading dyno, thats probably over 450 on the other dyno you were on. what were your mods on your last sti? if it was just stage 2 thats easily 450 on that dyno. unless its a real chitty tune.

The old sti with 347 had 3.5"tbe, inlet, cai, fmic, and utec.

I can't just hook the meth up can I? Wouldn't I need to retune it? If I need to retune I may get different em. Not sure of any ecutek tuners around maryland.

looks pretty low for a dynojet.

Is this on the 2.0 or a 2.5? you should really fill out your profile, so we know what you are working with

edit: yes you need to retune for meth, like other things..you can run it, but it will do you no good other than cooling and could just cause HUUUGE problems if not protuned

hey, I read your old numbers and thought you had 347whp on a dynojet; that's why I said it didn't look to great. My bad

ahh ok, no you are making right around the average amount of power

most say that a mustang dyno is 15-20% lower. The mustang dyno's just aren't fair when it comes to showing parasitic power loss, it makes these awd car's lose CRAZY hp on paper

my stock turbo STi put down 312/360 on race gas, my mustang dyno(gst motorsports dyno read stock STi's at ~210/210. So in actuality I was ~365-370whp with race gas..which is just nuts

so you are ~470whp, which makes perfect sense

if you aren't happy(which is crazy not to be at that level) use the meth or get some larger injectors and run E85

Awesome car, post up some pics in the members car gallery, and make sure to pop your hood

Good power for a 35R on a Mustang dyno...in line with the local one.

Personaly i think it is great power.. 400 on a mustang thats enough to rip the face off of any normal person.. Line it up against a car that pulls 400 on a dynojet you will feel bad for the poor guy when you compare the trap speeds.

I am thinking of possibly getting different em and hooking the meth up. Not really sure though. 400 for a mostly street driven cars seems plenty to play with to me. Also with just having the forged pistons I don't want to shorten the life of the motor even more with running more boost. I spoke with the tuner and was told it was a very conservative tune, so with that being said prolly jus tleave it. Atleas tuntil it goes then go hp crazy.

You can get 93 octane in MD correct ? Take it to Agile,get it tuned on their dynapack for 93 octane and you will be happy.

It's already been tuned for 93 I just found out the other day. The sam etuner who tuned it originally flew out and retuned it on 93.

93oct + 24psi on a 35R != Conservative.

On METH that would be conservative, on pump noway. It was mentioned above on anything but a Mustang your making 430-450WHP.

Yeah I quoted that wrong. It was at 22psi. I talked to the guy who tuned it.

On a dynapack, my FP GReen made 327whp/326 lb-tq on 20 PSI

On a dynojet, my VF39 setup produced 287 whp/ 325 lb-tq on 19 PSI

I can feel a big difference between turbos, so my guess the dynapack reads lower. But you should take into consideration how its calibrated by the tuner. Some dynos read higher and some just read lower naturally.

I agree totally. With my old sti that had everything except turbo I made 349whp/347tq. That shows the difference in just the two dynapacks we were on.

dynapacks generally read higher than just every other dyno out there. Honestly I have never read about a 'low reading' dynapack.

Put that car on a dynapack and it'll probably make 450++awhp

How's she ride? I bet that .63a/r makes it pretty snappy on the street

i thought 35r setups were supposed to be 450hp/400tq...guess that is close if that dyno reads low.

According to?

Usually estimates like those will be based on a Dynojet...Mustangs are a whole different animal. Honestly, I see more variation between different Mustang Dynos than say one Dynojet to another. I think some just let the MD read lower (as it should) while others try to correct it to Dynojet levels.

Yeah and how aggresively is it tuned? You must have missed the part where I said this was a conservative tune with no meth. How about I get a retune and hook up the meth kit I have. Would be a whole different story. I really am not trying to go all out with this setup since it only has pistons.

Also what mods do you have with that setup? Those are definately some good numbers.
