Ok, here is the info on the supercharger: Mark has found a test car in Katy tx that is willing to go to Austin. He will start fixing up the supercharger to the car in about two weeks, and then he will begin manufacturine the kit as a complete kit, priced around 3.5thousand or so. I will keep you all updated from day to day.

Brendan,

Any word on whether this will work with the 16V S2's?

I am in if it will.

no word on the 16 valves yet. Mark said that to be safe, the kit would start out at about 5-6psi, about 60-70hp, but if you wanna do some mods to accomidate more boost, then crank that motha up. I'll keep you posted about the 16 valvers.

Think of the 968's too...they're just S2 motors with variocam. I know there's a good number of people over at 968.net that are interested in SC's for their cars. They've been waiting for Huntley Racing to release theirs.

Is that 60-70 hp at the wheels?

That brings up another question, what kind of drive line loss does a 944 have?

Greg Hammond

60-70 at the flywheel is still 51-60 at the wheels, so either way - it would be a considerable power upgrade.

Because the 944NA has a higher compression ratio and no means to reduce boost based on engine knock (the function of the KLR in a 951), the safe boost levels on the 944NA are naturally going to be lower.

How hard do you think it would be to just lower the compression - this requires new pistons? And what else? (sorry for the ignorance in the question).

You can reduce compression with thicker headgaskets. Numerous outfits make solid copper headgaskets. No serious boost freak would go without one. Also the gasket remains cooler because cooper conducts heat 8- to 10-times faster than the steel used in normal gaskets. Thus it can stand up to higher boost before burning through (it's not pressure that blows normal headgaskets, it's the intense heat from the detonation).

Dave

Isn't the head gasket supposed to be the weak link, so other (more expensive) parts aren't destroyed?

IceWater

YES! PLEASE FIND OUT ABOUT THE 968 AS WELL!

The kit that is coming from Huntley is expected to be about $6000 (and good for 100 hp).

Thanks,
Tom

3,500 for a additional 60-70 hp?
6,000 for a additional 100 hp?
how about 350 hp total for less than 3,000?
that what my renegade conversion is costing.
hmmmmm? just thinking on keys.

Matt O.

Well, not to get into this discussion once more, but 2-3K for the renegade kit doesn't include the engine (2K), radiator ($500??), and the various other items you will need (so they say).

Don't get me wrong, I would be the first one to do this, but for me I would never want to do it to the 944 I own now, it would have to be a donor 944 with a busted engine. So that means another 2-3K. Money I don't have, and if I did I doubt I would spend it on that (or a supercharger for that matter).

Hi,

Well, if the test car for whatever reason doesn't pan out, I have another 944 here in Austin that could be made available on short notice (I have half the bodywork off for painting anyway, so I wouldn't miss the thing right now anyway.)

Supercharging is not for free. The Vortech style supercharge is not a positive displacement like the Boxster or the Huntley (if it exists). You develop boost roughly as the square of the compressor speed. Thus, if you develop 5 psi boost at 6000 rpm, you will only have 1.25 boost at 3000 rpm.

This is not the case for PDL like the Eaton M 90 or the Autorotor line.

You can up cam for about the same amount and same result using a MAF.

Rog

Good point. That very non linear boost leaves you a fairly peaky motor. Very true that standard old hotrodding stuff (bigger cams, lower restriction intake/exhaust/TB) will do the same. To be worth it, some type of positive displacement unit should be used. Were they actually planning on a Vortex unit?
