Twin Screw Vortech Coming

You should step up and try out that 3.3L Jeff!

I would do a turbo before that.

+1. A 3.3 is a bit big for a street car with a 4.6L engine.

LOL!...................I guess a Whipple 3.4 is outta the question for you then.............as would be a F-1A

I don't know too big? Ask JR Lewis 9.12 @149 MPH thats the record holder! He runs a 3.4 Whipple and that was with a 100 mm throttle body.

Yes for me a 3.4L is a bit much for a steet car IMO. Trying to get 700rwhp and rwtq to hook up on the street in the low rpms is ridiculous. An F1A wouldn't be as bad considering the power is linear and you can get traction before the full onset of power. If I ever target 700 rwhp it will likely be through an F1A.

Just do a turbo so you won't have to worry with the belts on the F-1A. They are an absolute pain!!!

Thats what I hear. However, House of Boost now makes a dedicated drive for 2v and 4v's that should help tremendously. Would like to see some actual technical info in it and back to back comparison between dedicated drive and 8 rib alone. Could be cool.

Really? I'll have to check them out.
You still have to contend with the large blower and the amount of air the thing moves just at friggin' idle! LOL! It pretty much mandates a blow-thru MAF and lots of driveability tuning. I can't recall for SURE how well your stock computer deals with a F-1A, but I know even with a relativly fast(hahahaha!) Mach1 computer, it is still not fun tuning the car for acceptable drivability..........at least to OUR standards. I'd also make sure your current intercooler is large enough for that beast if you run an air to air intercooler.
