We found out our 88mm turbo was too small for our 433cuin LSX with LSX DR heads. These heads have massive flow so we ordered an F2 and hitting the forum for guys that did the big Procharger and can provide advise from experience.
I have heard of some belt issues, so did you guys go cog or ?

Thanks in advance you speed freaks.

I would get an F1X over the F2

The debate over f2 or f1x has been going on for a long time. I choose the f2 and run it (cog) on my solid roller 408. Makes good power.

A provoluted f2 will dominate an f1x (provoluted or not) according to SME, so thats my next blower mod.

I run it on the lsx transplant bracket and have not had one single belt issue yet.

What do you have going on man. Sounds like fun.

I love the Farks car.

If its running right, you'll run out of injector pretty quick with that F2. A lot of people don't realize how much extra fuel a procharged deal takes compared to a similar power turbo deal. An F2 will take anywhere from 250-300 hp just to turn it. Thats horsepower that requires fuel but does not show up at the crankshaft or tire. Step up to some ID2000's and you should be good to go provided your pump(s) keep up. I run twin 4303 pumps on mine with ID2000's.

The squash return system seems proven for high HP.

Blown are you running a cog or serpentine belt?
Any other tips are welcomed because no many run F2s and get over the 1000 rwhp on a street car.

Thanks

What kind of numbers and ET's are you shooting for? With the setup you've mentioned, I don't see why it won't make 1,200 rwhp+. The ID2000 injectors would be a good idea.
