What do people see with the stock turbo? I know you can pick up some pretty good times with the VF39 and a meth kit. Mike at innovative tuning believes that he can run 12's with a little bit of juice on top of it.

What have other people done? I am looking to maybe spray, but most likely just use a combination of 12 psi on a VF39 so that I can keep it with stock fuel control, and not use a meth kit. That should be able to get me at least deep into the 14's, but i'd imagine high 13's.

What have you all been getting for times/dyno's?

VF39? That's not the stock turbo. At least not on the EJ22T.

I guess my post was two tailed. I know what it does with the VF39, its 13's pretty easy, so I want to see what people can do with the stock turbo.

okay. Well, the stocker is going to be much more limited, but I'm sure you guessed that.

Of course, I just want to see how much less I am new to the subaru world, and trying to take in as much as i can, so that I can help others.

Ok, this is the dyno plot from a completely stock 93 turbo sedan

Nice! Our car's are heavy huh, hehe. About a thousand pounds more then my neon. I've been asking around, but no one has really answered it yet. How much boost does the car make in its total stock form? Its like 8 psi, right?

wow 136whp??? Thats pretty good for stock, I think so at least...

Yeah stock boost is like 8.7psi I think, my boost gauge reads about 9psi so its around there.

It may be a pretty low HP (at least I think) for the car's weight, but the torque curve is so flat, it has a lot of potential

Wow that stock dyno is considerably higher than the factory 160 crank hp rating would suggest.

And Mark...you're goin down buddy. I don't care if I have to put a third meth nozzle on the beater to make it happen. LOL

I'm still waiting on a 6 puck disk and a new throw out bearing so it looks like I'm going to miss taking the beater to the strip this season.

Hah, yes, I think you'll have me, you have a little bit more knowledege them me when it comes to these motors I do want to give some STi's a run for their money though. I'll come down to the shop and plan out what i'm gonna need to have it happen one of these days. In the meanwhile, i'm gonna get this puppy intercooled

Not exactly stock.... 190 whp and 200 torque

But DOHC heads, 550 sti injectors and 11-12 psi. Have since tuned it a little better, probably gained about 5-10 hp over the entire curve, but no proof.

Nice numbers. What turbo are you running?

I believe Doug is using an Eaton type supercharger of some sort.

I know a guy who is the master of superchargers around here :snky: M90 FTW

Doug runs an M62 off a Mercedes. I've got an M90 sitting five feet from me right now.

I would run an M90 in a second. IFFFFFFFFF I could get the M62 clutch setup hooked up to it. The nose of the M90 is way long.

It would give me 25% more airflow. So instead of 12 psi, it would be 15-17 psi!

The M90 takes 90 HP to spin though (with a 2.55 pulley at least), so its a pretty big parasitic loss. Its kinda cool, but i'd slap a big turbo on instead of the custom work it would take for the M90. It is a pretty great blower though. Intercooled, and ported, they blow well

--mark

The parasitic loss is dependant upon the power its pushing.....

I am definatlely losing some power due to parasitic loss, but I doubt as much as a 4.4 liter motor..... ie, its dependant upon the motor itself...

Yeah, I know on a GM 3800 , its ~ 90 HP to move it. Thats the only motor i'm very familiar with when it comes to the M90 blower. I've spent too much time around one
