Wondering why nobody goes the Procharger F1 route. Lethal has a complete kit for the 03/04's with an F1. I have tossed around the idea of A F1 and don't know why I don't see more. I know it won't make the power of a turbo but is that the only reason?
The reason why alot of people don't run them is due to the issues that they run into. I know a few people who have gone that route and switched back to the Eaton, KB or Whipple.

You need to change the intake manifold and not use the 03-04 factor intercooler with that top hat sheet metal shit intake on it. The runners on our lower intake are too short so you get puck all for bottom end and midrange with the Procharger setup for our cars.
Basically if you want it to work you need a 12 rib or cog pulley(spraged if you are a stick so you don't damage the head unit) an air to air intercooler and then a different manifold.
If you do that it should make sick power.

you need to drive a centrifugal blown car and you'll see the difference. Positive displacement blown cars are so much more fun to drive. If you are making a drag only car the F1 may be a good choice for some big peak numbers when you stay in the high rpms all the way down the track making a pass.
I had a Novi 2000 that made 708 RWHP and it felt like a 300 RWHP car until about 5,500 rpms then all the power rushed in at once straight to the rev limiter and no tires had a chance of holding traction when in 200-300 rpm increments 400 more RWHP came in all at once.
now the Novi 2000 was fun from about a 80 mph roll !!!!!!!!! OMG !!! I hurt a lot of motorcycles feelings real bad but it had no low end grunt like the Eaton, or TS blowers do. No little quick blips of the throttle ever impressed anyone I had to drive the shit out of the car in high rpms and at high speeds to impress anyone even myself with that set up.
But normal driving around town I was very disappointed. I fell in love with my car all over again when I ditched the Novi 2000 for a KB 2.2 and life was great after that !.....until I had to sell the car - damn ex-wife

Yea, I know it needs a new lower but that comes in the kit. Don't remember price on it but it's less than a turbo. Would def get the cog drive setup also.

I haven't been in any big power turbo cars so I can't compare to turbos from expierence, but from what I can tell you get bigger numbers with a turbo, and ALOT more torque with a turbo that a centri blower. Keep in mind the centri blower build boost with rpm while turbo build boost more sililar to positive displacement blowers just not as quick.
this centri blown graph looks fairyl progressive but I assue you it felt very different on the street unless like I said I was rolling at 80mph.
In general, the ProCharger is not a great street/occasional race option. Low end torque is very different from a twin-screw or even the Eaton. For the track I would definitely at least consider the F1. That's not to say that everyone would dislike an F1 for the street. I think that if anyone is considering the F1 that you try to drive both a TS and F1 setup to compare.
Red3, keep in mind that the TS has more potential than a ported Eaton, even with a nitrous with each. For most folks I would say a ported Eaton (especially with a shot of nitrous) is plenty. But they don't sell a lot of twin screws for nothing. :-)

Thanks, but it still doesn't matter that I port for a business. Anyone can pm me anytime they want to.

I have a F1A on my 03 cobra and agree with 68_GT. You wouldn't even know its on the car (despite the loud BOV air rushing sound) until later in the RPMs. When it kicks in, its just sick. Its like driving on ice trying to keep the keep in a straight line.

Wouldnt it be very similar to a turbo?
No it doesn't come with a new lower since it uses the factory lower intake and intercooler for cooling.
You need to ditch that whole cobra intercooler and lower and use a Mach 1 style intake or Sullivan, sheet metal would be the ticket, but big $$$ there.
That kit is a waste as designed, you are better to go from scratch with a better bracket, F1a-F1c head unit and big air to air intercooler. Fab up your own piping and go.
A properly setup centri will hand a 2.2-3.4 twinscrew car its ass. Our stock motors aren't ideal either with 8.5:1 compression, you want it up around that 9.5:1 mark. That will help with bottom end.
The shift point highlights the problems to me Josh...
Is it a stock longblock? I think if he spins it and sets it up better his impression will change.
Ya I am not sure on it. When we went to drop off Sinultrous car at MPH we talked about it on the way home. They were trying to race old men in stock corvettes and were getting killed. So he bitched about the lack of low end.
so more or less like a turbo also? Correct
Except the turbo has pure boost with not having any parasitic loss from taking power from the motor.
No, not like a turbo....
Twin 57's have pretty much zero lag and they can support ~900rwhp so I can't understand how anyone could possibly pick a procharger setup over a turbo setup.
The centrifugal supercharger to me is basically a hybrid between a roots/twinscrew and a turbocharger, but instead of having all the strengths of the two it has all of the weaknesses....

I tend to agree with what you said. And because that "middle" slot is so narrow most who want more than a twin-screw has to offer go to the twin turbo setup. It would be interesting to know the percentage breakdown (Terminators) between ported Eaton, twin screw, ProCharger and twin turbo.

That is correct but what keeps people on the procharger instead of turbos is usually the price.
Brian told me all how to do it before he went into business doing them. Great guy there
