New Charger in Testing:

[McRat]

This is a plug-n-play replacement for the GT4202R, but with 13% more air available. That means about 500 more RPM before you see fade, which should be able to get you another 100rwhp at 4500rpm.

While it is form identical to the 42, it has a 3.2x inducer, which puts it out of range for most sled pulling organizations. It is not intended to be a street charger.

It is a T4 mount. If testing is successful, I will make these available to McRat customers. I will be testing at Famoso in a couple weeks.

The charger on the left is a GT4202, the charger on the right is the GT42 Mutant.

Ball Bearing?
Can it be had in non ball bearing?
Can you PM me a price?

 

[McRat]

Let's see if it works first!

Then I will get pricing for Team Salad guys.

 

[McRat]

The test model is ball-bearing, but I will try and get some plain bearing ones.

 

[MAXLLY]

Mutant 42 is right... looks like a mix of 42 and 45 stuff.

Are you familiar with "Forced Induction" company? St Louis I think?

Good luck Pat. Looks like fun stuff.

 

[JOHNBOY]

A 45 comp wheel is.
81mm (3.181")/108mm (4.251")

It is not intended to be a street charger.

Would this make it a good candidate for twins then or is it not big enough for that?

 

[McRat]

It would make a good primary for twins that use the stock charger, but it's intended for high RPM single charger racing.

A regular GT45 will not fit on our trucks easily without alot of custom fabrication. This gives you the best of both worlds.

Turbine side changes?

 

[McRat]

Turbine side changes?

13% more turbine flow, but with the same A/R of 1.15. Still same vband as normal 42.

 

[dieselson]

So this is the one that is going on casper? I can't wait to hear how this goes, could it be a possible bottom turbo for a street twin combo?

 

[McRat]

It's pretty big. More like a primary charger for twins.

Just make sure you set a little time aside for me and Casper before the 23rd. I need to dial him in.
