Sts Turbo Dyno #'s Inside
Sts Turbo Dyno #'s Inside I just came back from Eastside Performance. We were dyno tuning a 2002 WS6 Trans Am. The car is 100% bone stock besides the STS base turbo kit with a t-60 turbo and meth. injection.The only other thing we added to this car were 43# injectors to keep it safe. This car is an automatic with stock exhaust and cats.
At 5.5 # of boost the car put down 405.0 rwhp & 411.6 ft lbs of torque.
At 6.5 # of boost with some meth. 420.2 rwhp & 428.1 ft lbs of torque.
We will be going back to the dyno within two weeks. We will be trying more boost and less meth. We didn't have any smaller nozzles with us at the dyno to swap out on the meth.The problem we had was when the meth turned on it was just flooding in. The air to fuel ratio went of the chart to pig rich. We'll be straightening out our meth problems before going back to the dyno.On a good tune I'm very confident that we should see 450+ rwhp next time.

just asking, but if you have bigger injectors...why are you bothering with meth. Meth is for someone on stock injectors and running more then 5#.
I would keep off the meth if you have the 43(42?)# injectors in the car and setup correctly(Injector Flow Rate table) and then also have fuel delievered in the Power Enrichment Table. (Didn't mean to make you sound like you were a drug dealer
).
I'll be looking forward to the new dyno numbers. Good luck!

Went from 240deg IATs at 13psi to 107deg. From 140deg IATs at 6psi to 80deg.......... This is with 70deg ambient temps.

more accurately the stock signal for the wastegate is directly off the turbo.
thus when you throw and IC in front it has no idea you did and that there is pressure loss. take the signal from the manifold instead of the turbo and viola the wastegate does it's job and maintains the boost pressure you set.

5psi will put his IATs at about 140-150deg. 10psi will push you to 190deg or more.

What was his baseline dyno?
My friends 02 TA WS6 auto baselined at 297rwhp. If 300hp is representative for a stock auto that is a 35% increase over stock (assuming a 18% drivetrain loss) which is right in line with what 5.5lbs of boost should provide. Great numbers and another notch in the STS belt for delivering exactly as promised.

Jo'l napot kivanok!
Nice run, we'll talk more about this later but I thought I would post the following suggestions straight from the horses mouth (Rick Squires).
Here at STS we ran 5psi with the stock injectors on a bone stock car and put down 416rwhp. The stock injectors were probably running a little lean compared to your 43# injectors.
Remember Methanol displaces 2 psi and seems to be perform best after 7.5 psi. Essentially at 6.5 psi you were pushing as much air as at 4.5 PSI and with much richer settings. You still saw a gain to 420.2 rwhp because of the cooling effect. We usually run 8 psi with the methanol, using an EBC that switches from 5 psi to 8 psi while also arming the Methanol. With 8 psi and methanol we usually ran around 490-500 rwhp.
Next time why don’t you try running 8 psi and the methanol. Also make sure to check the following:
You should be running with the M10 nozzle (not the M15). Make sure your pump is the smaller pump with the 4.5" body(metal part) and not the 5.5" body. Your methanol mix should be between 50/50 and straight methanol.
We'll talk more later.
Visszont!
