Has anyone ever tuned or seen a BONE STOCK sti at 19 psi? Im curious as to what it would put down and how the dyno plot curve would look.

 

[Batmobile_Engage]

The Batmobile was once tuned for 20 psi on the factory turbo. Obviously, that turbo wasn't big enough to continue supplying 20 psi to redline. I think boost had dropped off to 9-10 psi by 7000rpms.

You said factory turbo. I said BONE STOCK car. Are we referring to the same thing?

Stock downpipe
Stock catback
Stock everything

Maybe you guys can do that to me lol. But I still would need the cable or ap. Which may take awhile.

Tactrix, aem uego, dp o2 bung.

Im really really really really really curious to see what a bone stock car would push to the wheels with one of [MENTION=9]HolyCrapItsFast[/MENTION] tunes!

I have, I've tuned a factory bone stock STi to 19 psi, but it's kind of pointless, a lot of restriction in the factory exhaust system. It creates a shit load of back pressure with both the cats in place. And having the stock Downpipe bottle neck at the exducer side of the turbo creates a lot of turbulence and causes wastegate chatter at anything past 17 psi.

What power did it make?

 

[TK-421]

Just a hair under 280hp and 295 wtq on a mustang dyno with correction factor. One of the guys at the old shop had picked up a brand new STi and wanted me to push it. I asked him if he drank the bong water too.

Dang thats great for a bone stock! :ty:

Yeah it is, but! The turbo ended up shitting the bed about 3 weeks later due to the increased exhaust gas pressures

You're right, I guess I didn't read thoroughly.

That was with a catted Cobb DP, Cobb 3" catback, a short ram intake and a Walbro 255.

Fantastic news! Did he built it afterwards?

No he replaced the turbo under warranty and then traded it in on a C7 Stingray

:rofl: wow

 

[TK-421]

And mind you the injector duty cycle was maxed wayyyyy the hell out and the pump was screaming like a Japanese school girl being molested

How exactly did that turbo shit the bed? Standard VF39 wastegate crack? That's how my old VF39 died.
