Drivability and Issues
The drivability with the supercharger is excellent. You wouldn’t even know it was there unless you put your foot into it, then you definitely know it is there. The cold start fuel map is challenged probably by the larger injectors. The ’95 does not have a cold start injector and the stock ECU over controls resulting in a +/- 50 rpm when first started. The over control gets worse, to the point of stall, if you touch the throttle while the ECU is working on finding the right rpm (takes about 90 seconds). The options are to not touch the throttle or step up the idle with your foot.
The stock ECU handles the supercharger very well. It feels a little sluggish at low boost and light throttle, it would benefit from a tune. At medium to full throttle it is a freight train torque monster and has no issues, the M112 builds boost quickly and steadily to red line. Traction control gets a little excited, but that’s no surprise.
Issues
•Need to upgrade the exhaust, the stock exhaust doesn’t cut the extra flow under boost.
•I have a no name stage 2 clutch which is not cutting it. Need to beef up the clutch to handle the torque.
•Need to upgrade the rear suspension. The rear suspension is torque steering under boost.
•Gearing too short. With the five speed and boost the engine hits red line in first and second before you think to shift. With some training and track time I’m sure it would be fine. However, I installed the later model 3.27 differential which greatly improved highway performance and provides more than adequate street performance.
Bottom line is I like it a lot!
