TDR member, paulb, ran the cool twist on his 2nd gen. It's a daily driver and very mean on the strip due to Paul's excellent driving skills. If he doesn't see this post, you could send him a pm.

I put one on about 1/3 of the way through last race season. It worked out very well for me. It seemed to be a very durable turbo. I can't count the number of times that I barked it. In fact my girl friend was disappointed when I went to twins because of no more barking! :-laf For a turbo it's size it spools well, and even though I don't tow heavy, it work okay towing my travel trailer. For me a wastegate setting of 45psi worked the best. At a 450hp power level max EGT's would hit 1400*. The 35/40 hybrid that I had on it before would hit 1600*+, at the same power level. This was doing 14psi launches, running 13. 49's in the 1/4 mile. Once I got used to the larger turbo, my consistency improved in the 1/4 mile.



I see you have a 12V. I don't have any experience with it and 12V's...



Hope this helps...

P. S. I think Rip has my Cool Twist for sale...

This is all of the info that I found so far-Nicholas

That looks to be about a 58mm compressor wheel and a clipped 60mm turbine wheel.



Thats probably good for 400hp maybe 425hp.



For the same money you could get a Phat Shaft or HTB2 that will bolt on outflow that unit.

its a 62 ... ... ... ...

 

[jwilliams3]

Even if it is a 62mm you still have to run a compressor outlet adapter for either the 94-02 or 03-05 trucks according to that picture.

With an HTb2 or PS62 they are straight bolt on units that dont require the extra work.

 

[McDowra]

it comes with a vband flange or hose outlet your choice. For the second gen trucks it needs no adapter.

I was UN happy with mine on my '97. I couldn't tow with it. It was OK empty, but EGT where 1300 + on flat ground pulling mt 5th wheel at 55 mph. I sold the truck shortly after that to some one who wasn't going to tow with it.
