Here we go. ..it can't be done they say. It won't make more than X amount of power. You can't make more than X amount of boost with that turbo.
Did you even know that the 5830 could produce 58 psi of boost and move 60 lbs/min at the same time ? Looking at the chart you wouldn't know.
Did you notice some Garett compressor maps changed after drag racers proved them wrong about their model predictions (airflow chart)

We race on classes where we are often restricted in the turbocharger size and sometimes MODEL. We aren't allowed to change wheels or housings.
We have to find ways to maximise power through other means. That's my specialty. I always under turbo and get excellent spool up caracteristics.

We get 340HP @ 30 psi (crank) through a turbo that is rated at only 260HP maxed out. This is what we have to do to have the record e.t and mph for the class.


I will say this, I have not built any GTP but I understand motors and turbos very well. How many Turbo GTPs are out there with that exact turbo?
Not many.

I will put that turbo just to prove a point and I'll dyno it.

P.S. I know the 6262 is a better suited turbo for a 3.8L V6 but there is no way it spools as hard as the 5830.
The 5830 will make my 500whp goal.
