Well ive been trying to search and havent really found anything. Assuming that i have all the basic bolt ons and a good tune, on stock motor and tranny still, how much awhp is the evo 9 stock turbo good until? I mean what is really the most power it can make? The reason i ask is because me and a few friends of mine were having a debate about this, and i figured you guys would know best!

 

350-400 awhp on a good tune with supporting mods and some corn juice. A few have gotten over that mark, but not many.

 

(Sqrt(144)/e^76ln(5.6))*arctan(3pi/2)

 

English racing has taken the stock turbo to 522awhp...there are too many factors to give a set amount of hp a stock turbo can make

and extreme tuners have taken it even further...

 

whoa that amazing 10.8 on the 1/4.

 

Its a 10.8, not a 10.2.

 

For the average person, you can get it to about 400 - 450 with full bolt ons and e85. I was able to max mine at 425awhp, with no porting, no cams

 

the torque is the real number to look at, or what i like most... torque kills but it also thrills. i've frequently seen the stock 9 turbo make torque in the 400-475 range, and HP from 380-440. im sure it has gone higher, no telling reliability though

 

We just went 10.5@128 on a stock 8 turbo. yesterday we swapped it with a 9 turbo and were able to pick up a bit of power. The same car is now making 430 tq and 429 whp making it the highest HP stock turbo Evo I have seen on our dyno yet. I really do not think there is anymore left in it. Its tapped out at 34 psi.

That turbo is heavily ported and built motor that has no a/c or ps, electric wp, 10:1 comp, lightweight rods, and built head on e90 with almost 34 psi... Not the norm for most stock 9 turbo guys but very impressive.

 

Typically around 400whp and tq on a Dynojet. Don't believe the bs numbers you read on this site lately though as they are using a software program and setting the weight to ridiculous numbers

 

Highest I've seen is maybe 405whp on GST's Mustang Dyno

 

LOL. The VDR software is a great tool. I would not write it off quite that quick.

A local DynoJet shop out here made 440/440, on e85 @ 32psi. I have seen quite a few dyno graphs with mid 400's.

So I was say at 28psi, you sould be 420-430 hp and tq, and depending on your setup SD or MAF you should be able to get into the mid 400's.

 

About 400whp and the stock turbo is about maxed out
