New TURBO NC for XP Class...Our New "NC-EXTREME" PROJECT!
Posted: Tue Dec 07, 2010 1:59 pm
Hi Guys
Last night a famous drifting NC left K1 Speed and landed in front of my house. The question is now...what do we do with it? We already have NCLIGHT as our dedicated track toy under development. My first thought is to sell our Cosworth supercharged NC and convert this drifter into an XP or DP class Autocrosser! My first choice is be crazy and go XP!
XP Class.
The current champ is FrankenLotus and it would be a VERY big challenge to try and match that car, might take a few seasons of dedicated effort only to finish second place. But, we have the parts here ready to do it. Got a fresh 2.3 dry sump Cosworth built motor with 9.5:1 Cr pistons...built for boost with their strongest rods to handle over 400 hp (though XP class means a 52mm restrictor and that means less peak hp). This car is ALREADY configured for the 2.3 motor...complete with Motec ECU and trunk mounted oil sump. The motor would be plug and play. Also got a Bell Turbo kit with turbo sized for the 2.3 motor. We have some minor plumbing issues but relatively direct install. The drawback of the Xp choice includes the fact that competition is very stiff, and we would need to hack this car down to the minimum 1844 pound weight of the class with this displacement. Part of me really hates the idea of hacking out the cage. This cage was installed into a bare shell that was stitch welded and powdercoated as a unit. LOTS and LOTS of work to get down to weight...unless we get really crazy and load a V8 into it which would raise our class min weight way up over what it is now. We have the parts here to do the 2.3 turbo...that's a logical choice.
DP Class
As Ron Bauer noted in miata.net thread, Current (without wheel adder) weight is a generous 2150 - New proposed rule would change that to 2070 (weight loss of 80 pounds), still easily done from our experience with NC LIGHT. Thus, not near the work on chopping up the car...the cage could stay. But, we can't use the engine and turbo kit we have...would need to build a 2.0 for the project. Could transfer from the 2.3 in the car now the barrel throttle body and head and dry sump plate.
So, the choice is the bigger challenge of XP (and its HIGHER costs long term to be competitive), versus DP which means more up front cost in building the motor but the overall car would be ready for class very quickly.
