Single Turbo Project

Is that enough turbo for a 3.7 that revs to 7500rpm?

That's the same size turbo that's in the BP kit. Maybe 5% smaller.

If that's the case he should be fine. I've just seen single GT35s used more often on much smaller motors.

Ummm unless I'm wrong...

The GTX3582R has a Turbine wheel diameter of 35mm and a Compressor wheel diameter of 82mm.

BPs Precision 6266 has a turbine wheel diameter of 62mm and Compressor wheel diameter of 66mm.

I couldnt find any hard numbers on BPs numbers and if that is exactly what they mean with the precision turbo but I did find this for the garretts.

Garrett Turbo GT Series Model Designations | Garrett By Honeywell

So if im correct the turbine wheel is almost half the size of BPs and the compressor is 80% of it.

This compares the 6262 but they are very similar.

Here are the specs for the GTX35R:

Here are the specs for the PTE6262

Compressor-

BILLET Wheel Inducer: 62mm

Wheel Exducer: 82mm

Turbine Wheel -

Wheel Inducer: 72mm

Wheel Exducer: 62mm

You will notice that they are identical on the compressor side of things, but where they are different is on the exhaust side of things. The PTE6262 has a 72mm inducer size turbine while the turbine inducer size on the GTX3582R is 68mm. It is no surprise then the 6262 makes more peak power up top, while most dyno’s have shown the GTX35582R to have more midrange power.
