Have you seen any dyno #'s using these on a stock motor?



you tell me! I know you know all these answers....

stock internal motor with 13k, babied. I do not track the car nor abuse it, no drag racing like some other fast yellow bird running around this forum.

Not sure where the true threshold lies, really will leave that up to Tony and where he feels comfortable.

looking down the road for the next phase of the car.


not much, you will need more fuel (injectors, possibly additional fuel pump)
internals depending on how much you want to crank up the boost

Good Luck. It would be interesting what Tony thinks the max whp will be on a stock motor.

I have no clue what real world results are for these turbo's.

635-675awhp on his Mustang Dyno is usually where he will want to cap it off for a stock motor car depending on Fuel used, Fuel system used and owner of the car. -> 680-725whp on Dynojet. i made 700 whp stock motor at 1.55bar Alpha30s 93+meth and beat on that setup for a while

there is really no benefit of doing the 71s at all. you might get 100 rpm of spool and a lot less top end. you want the top end of 76s. top end is not what damages rods, midrange is. thats why most motors that you hear about actually popping were A28 cars.

Uh oh Paulie. You're making more than that with your 24/20's on a stock motor. Looks like you'd Better turn your boost down.

Powell, how much were you making on a stock motor? Did you get to tear it down after running that power level for awhile? What fuel? Thanks.
