e36 325 competitive?

[lateapex911]

I agree! I just wanted to see what folks might be thinking...

I am curious what the Flatout guys will end up building for 2010. Did you make up your mind yet, Andy?

I have been told that there are those that have figured out the restricter and have their "S" cars almost as fast as before. Were I going "S", that is the way I would go, being a BMW guy, and all that. I think the open ECU rule has helped quite a bit. Chuck

Chuck, I'd like to see the E36 come back to ITS with reasonable HP levels. Do you know who has done this (figured out the restrictor)?

I have the KVS e36. I have run it with the restrictor in BMW and PBOC along with a few test days. I have Chets 240z to compare lap times with. I have run a 145.2 at Barbers this past march with the BMW club with the restrictor on 15 inch wheels. I have a chipped dme and have also run a custom AEM ecu also. They can be competitive, the power is pretty dull and flat. The restrictor turns the e36 into more of a momentum car than a power car. The handling stinks compared to my zcars but it does have great brakes. If you can learn how to drive them as a momentum car they can be competitive. A much better fit in ITR with out the restrictor. With out the vin rule change control arms and motor and make a 328? The restrictor makes improvements from tuning with the vanos pretty much useless.

Another note. Chasis dyno comparing the 240 with sunbelt power to the e36 the restrictor needs to be at 31 or 32 mm to give the same power to weight ratio. There are alot of 240z out there with over 180hp at the wheels. I did use a different restrictor than the Raetech for the best result. The GCR defines what the restrictor must be and for how long. I dont buy into the theory that the restrictor has to bee as far from the intake valves as possible

If you find a fast ITS E36 check under the hood. I've heard of a few who just didn't bother with the restrictor. I don't believe tech ever checked ours, and they certainly didn't do the stall test.

Not true, when I raced ITS w/ restrictor, SCCA Tech made me open my hood and show them the SIR...I broke the track record with it @ Mid Ohio, with medocare suspension.

I plan to be in ITR next year. We've got a pretty good idea what we're building - but things may change as we keep doing research. I'll say this much: there's a chance the Land of the Rising Sun will do battle with Deutschland.
