I just intalled the 20g turbo from deadboltspeed.com . along with the perrin 815cc injectors, walboro 255 fuel pump. Im breaking it in right now and gonna have it dynoed and tuned on the 8th of Dec. I was just wandering how much power to expect on a mustang dyno? I.m hoping for about 400 to 450 horses to the fly, so that would be hopefully somewhere around 380 ponies to the wheels. Just wandering if I was in the right ball park. Anyone with this setup please leave your numbers. THanks

 

I also will be running 93 oct.

 

Probably a little less than 350whp.

 

I also have a 3in exhaust ,no cats, cobb shortram. I will post my numbers after i get it dynoed on the 8th. Prob looking to run about 19psi not unless i have one of the sti s that can handle the extra pound to 20psi.. Im having Boxter4Racing to tune the car. So far they have done an awesome job on installing all the parts.


Please post any numbers of similar setups!!!!!Thanks

 

On a mustang dyno the numbers of my set up made was 350hp and 304ft pds of torque to the wheels. 491hp to the crank..

 

i was close

 

any dyno plots yet?

 

On a Mustang dyno where stock STI's run 215 whp, my '05 STI ran 296 whp at 20 psi trailing to 17 psi with 20G, 860 Helixes, Spearco TMIC, 255 Walbro, headers, Greddy EV02 catless TBE and an Ecutek tune. That would have to be a really high reading Mustang dyno for you to get anywhere near 350 whp with similar mods to mine on your planned set up. However, I was on 91 octane in Ca, so that would certainly make a difference. Adding an SMC meth kit only bumped me up to 312 whp on this dyno with 337 wtq. However, that's probably 375 whp on a Dynojet.

 

ehhh... MY 05 STi slapped 283 whp and 333 lbs of torque to a Mustang dyno
Mods at the time where : helix d/p, hks carbon ti cbe, arc box, cobb ap stg2 w/ protune.. boost was 17.3 tapering to 13 by redline

where did u get it dyno'd at??

 

looks like you need to check over everything for leaks and maybe get a compression test done.

 

Gruppe-S has posted many times before that stock STi's only get 215 whp on their dyno(I believe it is a Mustang dyno as well). They're dyno numbers are traditionaly pretty conservative judging by other STi's on other dynos. 235+ whp is typicaly what I've seen out of stock STi's so I think dude's car is fine if his car was run on a Mustang dyno.

 

i made 268whp at gruppe-s with a downpipe and ecutek. Baseline was 230whp

 

268 whp on TBE and engine managment is a pretty low number(if you have an STi). Generally most STi's with similar mods do 275+ whp on other dynos and what I have seen from people here, as well as personal experience.

 

untuned i ran 275whp and 300wtq on that same dyno. stock turbo and injectors.

 

and btw, theres no point in comparing numbers between different dynos. I can make 1000whp with the same set up on a different mustang dyno.
If you wanna compare between different mustangs just change the calibration to the same number as the other shop/dyno with the same type of dyno
