I'm thinking of putting one of Speedforce Racing's superchargers on my 1984 NA 944. I restored the car and am kind of attached to it, so I don't want to sell it and buy a Turbo. Anyone have experience with this product or company?

Quickest way to a new engine, supercharging cost me a new long block and a ton of headaches. Keep your NA ad add a turbo to your garage as well, you will be happier in the end.

Scott, did you rebuild the motor prior to putting the supercharger on or did you just slap it on a high compression old motor? I'm just curious because I was thinking about getting a Huntley Supercharger but rebuilding by motor w/ turbo pistons so I have a lower compression ratio. Just a thought. I'd like to know what you did to your block to damage it.

Yes indeed I think I had one of the first ever Supercharged 944's, here is a pic. Had to be the DUMBEST thing I have ever done, and I have done some pretty stupid stuff. The stupid yellow circled thing was a special "rising rate" fuel pressure regulator.

come to think of it, didn't Canepa or somebody do a supercharger kit for the '24 way back when? (late 70s)

I used to have a dyno sheet around here, but I think I tossed it. At 5 psi I dynoed around 178 HP. At 7 psi it was 180 or so, but at 7psi it destroyed the rings soon after.
The kit was 3000K then came the real expenses: new clutch (mine was worn alread) $450 ERL's Auqamist H2O injection system (in cylinder cooling and detnoation protection) $400 Rising rate FPR $450~475 New suspension, M030 setup $800 (used) Rebuilt turbo long block $3500 There was a ton of other stuff as well, I kept blowing $40 serp belts, and the Aeroquip oil hoses were a chunk of change as well. Then of course I needed to redo my cooling system to keep up with the power. DUMB DUMB DUMB, I should have just paind someone on the street $50 to kick me in the head and called it even.

Hmmm.....well there goes my hopes and dreams of getting around the insurance company. What to do now, is it possible to get a decent amt of hp from a 2.5L n/a? I am thinking I can get around 200 but I'm not sure. I don't want to sell by car but I would like either some force induction or some n/a hp without any turbo lag. I think my insurance will cancel me if I buy a 944 turbo. They don't like me too much. Hmmmmm......Any other stories of supercharger ups or downs?

we all want horsepower from our NAs, but it's hard to come by. Your best bet is to get your engine running to the best of its ability - that is, figure out the engine's weak points and fix them - and then upgrade the suspension and brakes. This will make your car faster than any engine upgrade ever could.
I remember reading somewhere (i think it was an EXCELLENCE suspension test) that every minor suspension upgrade is worth 100+ hp on the track. Even if this is an exaggeration, the point was well taken.

You can try nitrous, but the most steady state hp you're going to get without getting really crazy is about 190.
Rather than get on the hp crackpipe, you might want to think about making the car lighter. Quickness is a function of gearing and power to weight ratio. So, if getting more power is hard, it's easier to throw off weight. Look into cf fenders, hood, and a lexan hatch. Don't even try to have a thumpin' stereo cause they weigh a ton. Get a good aftermarket seat, they are generally about 20lbs with bracket as opposed to about 50 for the stocker. Be very careful which wheels you put on. Some of the replicas and the "blingin" ones weigh a bunch. Drilled rotors were introduced because they reduced unsprung weight, and cooled a little better. Every little bit helps here. Or you could just bolt in a Renegade conversion and forget it all. ![]()

Sounds like Renegade is the way to go. You can get the small block for $2000, another $2000 or so for their kit, and 40 - 60 hours labor. You get Chevy reliablity too.

If your going to do an engine swap and run it on the street be sure to check the laws with your local Department of motor vehicles. I went through a lot of trouble with a engine swap vehicle and then sold it to someone in the next state over because the laws were too strict in my state.

Swap in a 968 engine, 951 brakes, Koni yellows, 250# springs, M030 sway bars, and a 951 or S2 tranny.
That's a lot of work. It's easier and cheaper to buy a 951, S2, or 968. I was thinking along the same line as you. Check my sig.
