1999 C2 Supercharger is complete
Finally got my car back from EVO a few days ago. All I can say is WOW! Because the 1999 C2 is still a cable controlled accelerator, Todd was able to get 378 HP (SAE) out of the engine rather than the 352 HP (SAE) normally reached on a supercharged 3.4 (1999 C4 and all later models). This care screams through the gears, giving you little time between shifts due to the rev speed.
Easy 3.8 seconds 0 - 60 without burning the tires. Blew by my buddy's 2003 Viper who couldn't keep the back wheels on the road. Slight whistle at idle as the air is pumping into the intake. When the 350 lbs of torque kicks in at 5000 RPM, there is nothing holding you back. Torque and HP curve is almost constant above 5000 RPM with almost maximum torque from 5,000 to redline.
Unless you get on it, you would never know the car is Supercharged....but cruise above 4000 RPM and a touch of the accelertor provides for a quick reminder.
I'll post again after I put a few more thousand miles of fun on it.

I'd love to hear about your supercharged 996.... I'm curious about how the system works... does the supercharger operate only beyond 4000 rpm? do you have internal controls to bypass this system for improved gas mileage (I know many don't care about gas mileage... but it's nice if it gets more than 10 MPG 
)
1/4 mile times? 0-60 is faaaaaaaaast 3.8...wow!
can the stock gearbox and clutch handle all this power? also if you don't mind me asking... what is the cost for the evo kit?
cheers

All the details are at this sights: http://www.evoms.com/
I still get more than 20 MPG when I drive it hard. I am sure I'll get 25 plus at average highway speeds. Blower uses the engine belt pully (with longer belt) for the pump and therefore the SC is engaged at all times. Rev Limit is lowered to 6800 from 7200 which takes a little getting used to, but before you know it, your shifting at that point with ease. It was lowered for safety reason because the revs get up there so fast, it gives you a few hundred RPM's of safety before hitting redline. I presume you could increase the limit back to 7200, but I would rather not chance it and if are proficiant at shifting...you don't need to.
As far as the gearbox and clutch...If you plan on doing regular holeshots, get an old Mopar not a Porsche. I frankly don't do jack rabbit starts on a daily basis, but would rather get engaged and then get on it. I suppose if you put wider slicks on the car and popped the clutch at 6000 RPM you might have a problem (just like any other car) if the wheels do not break from the pavement. One of several things have to happen - wheels break - car leaps forward - or something gets twisted.

I wouldn't do wheel hops at all with that setup.... it should be fast enough so you don't need to spin the wheels to blow others away... and it sounds like it is!
How is your engine temperature... still @ 12 o'clock or or just a big higher?
The real fun is in-gear acceleration... I'll check out the site...
thanks for the info and keep us in the loop on what you think...

0-60 in 3.8s??? Is that theoretical or tested? A 2004 GT2 runs at 3175 lbs. (probably about the same as yours with the supercharger), puts forth 483HP and 472 lb-ft, and that is listed at 0-60 of 3.8 seconds. I don't see how a 378HP could match it. I know a supercharger is faster off the line than a turbocharger, all else being equal, but an extra 105HP, or 28% is no small amount. At 3.8 seconds, you've also matched the speed of a 500HP F50.
How did you test it?
What's the theoretical top speed?

Also... if you check Evo's web site then they list their supercharger package at 420HP for 1999-2001 models, and 470HP for 2002+ models.

Actual track time. First of all the weight of the car is less than 3050 lbs. The HP I stated was SAE HP and not the BHP horse power you are quoting for the GT2. The GT2's SAE HP is less than 400. My BHP is in excess of 450. That makes the GT2 only 7 percent more powerful. The 3.8 seconds was WITHOUT breaking the wheels...which if I did would probably reduce the time to 3.6 of less. Additionally, the GT2 is a turbo and therefore DOES NOT obtain the torque immediatley as a supercharged intake does. .
Additionally. the 1999 C2 has lower gear ratios than the GT2, providing much more thrust for the same amount of horsepower. I suspect that I wouldn't have any problems keeping up with a GT2 for about the first 130 MPH.
Top speed would be 166 mph with current gearing and rev limit. I never intend to go there either. Fastest I have taken it on the open road is 153 and that's more than fast enough. It's a bigger thrill is getting there so quickly.

As I stated in my first post...because the 1999 C2 (and ONLY the C2 not the 1999 C4) has a cable controlled accelerator, they were able to push out 378 SAE HP. If you look at the dyno charts listed on their web page....the display the C4 with only 352 (SAE) HP which is your 420 BHP. My 378 SAE HP gets me 450 +. In reality, every car they put a supercharger on is custom tuned and may vary from car to car.
