I would guess that packaging would be an issue as well. Have you ever seen the exhaust manifold setup on turbo M3s? Gotta be one of the ugliest setups out there. I would love to see some sort of short header into the turbo setup, but after going through that exercise, would the M3 benefit? I guess if you totally rebuild the engine to make it turbo worthy... Otherwise, a stock engine couldn't take more than 10 psi, right?

As I expected, they did give a little bit of added hp and torque in the midrange and, most importantly, at no point did the power fall below the baseline. The peak numbers changed very little but there was a maximum gain of about 7hp and 8 ft-lbs of torque at the wheels which is about what I expected. Here are the graphs with the before (Full Cam Kit) and after (Underdrive Pulleys) and I also included the run from when my car was Sharked with the Eurosport/Conforti CAI. I don't have a baseline run with my car stock so I couldn't add that. http://64.14.56.30/m3/underdrive/UnderdriveHP.jpg http://64.14.56.30/m3/underdrive/UnderdriveTorque.jpg -Wayne P.S. The reason for the strange dip below 3,500 RPM in the Full Cam Kit curve is because of the way that the guy doing the test pressed the accelerator so disregard that.

Many clubs do not let anyone other than students get a ride, so this is really very accommodating. If you wish to be the one giving rides (and taking the liability), then you can choose many other clubs to run with. Dan Snyder

Pit lane is at the exit of this turn and I just have time to yell at him to dive for the exit RIGHT NOW!. Which he nicely does, albeit at somewhat higher speed than considered normal for pit entry... Of course I'm thinking water pump, especially since his car is a 94 or so with plenty of miles. We idle in, I have him park next to my car and we start figuring out how he's going to get back to Ann Arbor (5-6 hours drive) with no car. Then I begin to wonder if anyone at the track has a spare water pump, especially since there's a Club Race that weekend with lots of E36 cars in trailers with tools, parts, etc. The first person I ask is instructor Dave Nihiser, who also usually does tech for Buckeye schools. Turns out that he has a complete E36 cooling system fixit kit with him: water pump, thermostat, thermostat housing, gaskets and O-rings, the works!!! Also a big-assed 32mm wrench for the fan clutch, already ground thin to fit. Sure enough the plastic impeller was in two large and many small pieces, with none of them connected to the water pump shaft any more. While my student missed driving on Sunday, he did learn how to replace the water pump and had the car ready to go home before the end of the day. Not too bad considering. Neil 96 M3

There's an easy solution to this problem -- don't run below 4k RPM! Seriously though, any differences are neglible, and are more than made up for in the improvement at the top end. Not to mention, most of us who bought the kit bought it for the track, where most of our time is spent at the high revs and the basic kit tends to run lean... -p ------------------------------------------------------------------------------------------- This message was sent using HiSpeed Technologies Webmail. http://www.hispeed.com

Most BMW CCA chapter autoX fees will be going up this summer/next year. All because CCA national has cancelled the autoX rebate program. In the past when a chapter ran an incident free event the national would reimburse it for the cost of insuring the event. When the insurance costs went up earlier this spring, the National opted to cancel this program altogether. The well established autoX programs will likely survive by raising the fees. But this places a very heavy burden on the fledgeling programs that take years to build up the constituency and brake even. If this is a concern to You, consider sharing it with your regional vice presidents and the National Board. alex f

I've also heard of people putting Supra engines into M3's. The real problem is packaging space. It's hard enough to get one to fit. Two can fit, but it requires a lot of compromises, such as moving the A/C and having long and complicated plumbing. Then there's the issue of tuning the engine and controlling the thing. IMO, none of the current single turbo designs for the M3 are worth a damn so moving to a twin turbo design is not necessary to make a big improvement. A decent single-turbo design would be a big step in the right direction, without the need for such complexity. -Matt --- Chris Curry <ccurry@curry.org> wrote: > > I have read that an excellent setup for a > twin-turboed car is the use of > a large and small turbo due to the increased power > output over the > entire range.

Most of the high horsepower RX7 TTs and Supra TTs are running a single turbo.

According to the instructions, the power must be stable at 12-14 volts for the 3-5 minutes it takes to transfer the software. It's primarily to ensure that the battery doesn't fall too low when loading, resulting in a non-running car and, if I remember correctly, the remote possibility that the job can't be reversed or redone.

From what I've read, it's recommended to have a battery charger connected to the battery during the "Sharking" process to ensure that there aren't any fluctuations in the battery voltage. A fluctuation can turn your DME into a $1200 paperweight :-) That's my understanding anyway; you can always call or email Josh at Eurosport to find out for sure.
