That doesnt mean its efficient lol

Of course lol. I should have clarified further....badass that the charger can take that kind of heavy abuse. I spun my BW 10psi out of its map, and the exhaust wheel practically came through my head unit.

That is all :evil

I wish i could go back in time and run the tuning that im using now, a ball bearing charger and see how things would have gone, i know up here the PTE 76mm ball bearing i had was a turd, but once it lit holy cow (on basically stock fuel) and crappy box tuning (mind you this was 3.5 years ago) I was always a little unsure of how good the gt42 based turbine wheel was compared to the gt45 like colton is running.

That being said i would love to try a gtx4202r again, i think it would work good for a solid 800 hp. I mean david lott made over 800 with a 7.3 LOL should be easy for a 6.4 to do haha J/K

What size nozzles would you run?

I've been kicking around the idea of a GTX4202R with a 62vgt, gating between to keep the atmo pushing. Stock fuel I shouldn't be able to drive it hard enough to hurt it..

Not enough turbine imho but it would spool great

Basically that's a set of high powers

Lead Foot Diesel has a 4202 on their RC/LB. It made some big power on 248C Dynojet.

890 when I dynoed it. That was backed up on Bean's dyno.

It hasn't been down the track successfully. It also doesn't have the proper safety equipment yet....at least it didn't last time I saw it.

780 at low boost. Couldn't hit full boost on the dyno without spray. Hoping there's a good dyno at Ennis so I can try for full boost on fuel.

Know what exhaust housing was in it?

Unless its a full load cell its probably not going to happen.

Have you had it to the track since?

A gtx4202r has more turbine that the pt7675 turbo I'm pretty sure.

I'm not sure what the specs are.

 

[Motostroker]

Is a 100% nozzle to much for this turbo?

Unfortunately, I have to agree. Very hard to light the turbo to its full potential on the dyno. Went to the 1/8th mile once in July but didn't have good results from my 60'.

IMO yes

Even stock compounds won't make anywhere near street boost on the dyno.
