Who's making 900+rwhp with a procharger on LS f-bodies? What's your setup? Headunit, belt type, fuel, etc? I feel like we don't see many big power procharged f-bodies. Thanks.

That's because most people making that power level are achieving it with a turbo. Not saying 900 at the tire isn't possible with a Procharged car, and I am sure there are a few, but its a lot easier to hit that level with a turbo.

I've got an ancient 21 year old LT1 engine, and I should be breaking 900+ (hopefully 1,000) to the wheels with my turbo setup. I was procharged and did near 700 at the tire.

I was making 890 with an f1c at 22 psi with a cog drive on an iorn 408. Now my twin turbo setup is making 1200 on 23 psi with more room to grow

You should be able to do 900rwhp with a F1A, F1C, F1R, F1X, etc. As long as you pay attention to details, it shouldn't be that hard. There have been D1SC setups in the 750+ rwhp range.

I got an f1a and probably in the 750/800 rwhp area. I think I probably hit 900 plus once everything is fine tuned but I agree turbo setup is going to get you there a lot faster and easier.

I was wondering about a procharger instead of turbo due to packaging. Keeping a/c is a must and I don't want fender exit exhaust but both of those don't seem feasible with a turbo capable of 900+ rwhp. It seems like keeping the a/c doesn't allow room for the exhaust to be plumbed to the rear of the car. I know many of the f series prochargers are capable of this power level but I didn't know if the f-body location was a limiting factor either due to belt limitations or intake hat/filter limitations.

It's not that hard to build a 900+ rwhp F Body using the Aster bracket. A 9.2/1 to 10.0/1 compression ratio well sealed LS engine along with an F-1A can get you 900 rwhp. Bob

Huron Speed makes an ac retaining turbo kit that will allow you to run the exhaust out the back. They are also super awesome to work with and will definitely set you up as well.

Everyone wants 1k these days! I just want to keep my car in one piece, after it gets another motor.

Which ever way you go your in good hands with Casey from Huron or Bob from brute speed!

Thanks, I appreciate it Jon!

The F-1A-94 is a newer blower that is softer down low than a F-1A, but it makes several hundred more hp up top. This would be a good blower for everyone looking for 1000+ rwhp. It still has the 9.00" volute diameter too. Bob

check out my build.. makin that 900# with huron ls v1 a/c kit. rad is in stock position and 4inch dump with cutout that necks to 3inch quickly that runs to back of car... sounds like a 13 second car at idle... lone behold runs mid 9's on 18lbs.... only a t4 s480.. theres only so many blowers but a million turbos.. theyre more efficient personally, and you can make a hybrid turbo to fit your exact goals

Bob thank you for bringing some value to this thread. Do you feel confident in an 8 rib belt setup supporting these F series blowers making this kind of power?

In terms of F-1A vs F-1A-94 do you have examples of the differences in power between the two units?

Bob@BruteSpeed

iTrader: (16)

You're welcome. Yes I do indeed. They are a lot of people on here using the Aster bracket making this kind of power. I don't have any comparisons to show you between the F-1A and F-1A-94, but the link below will give you some good info on the F-1A-94. Thanks. Bob
