I installed my Paxton Novi 1000 supercharger last weekend and after hunting down some oil leaks, got it running. I am posting the problem here because I think the problem has to do with a non-blower specific part - that and no one seems to care in the supercharger forums here.
Present setup (key items):
-Stock MAF
-Paxton Novi 1000 (new, 2 belt setup)
-Accufab 70mm TB
-FRPP Cobra Intake Manifold
-Stock Heads
-Stock Bottom End
-Crane Hi-6 Ignition
-MSD Blaster TFI Coil
-Jeg's Spiral Core Plug Wires
-Autolite 24's gapped to 0.040
-Paxton FMU for the stock 19# injectors
-Stock Fuel Pump
-Anderson Ford Motorsports PMS
-Base timing at 10*
The problem:
When the throttle is over 50%, in any gear, the car hits a "wall" around 2500-3000 RPM (according to the stock tach). Best I can describe, it feels like hitting a rev limiter - it just cuts out, interior lights (including dash/gauges) flicker. Letting off the gas and pushing in the clutch brings it back to life, so the car does not completely die when this happens. I am able to part throttle go until about 3500 RPM without problem (it may go higher, but I am not going to push it in case this problem could be doing some damage).
Troubleshooting I have done:
- The problem first happened before I installed the Crane Hi-6. So, I installed it hoping maybe (as some people on forums suggested) that I was experiencing spark blowout since the gap is on the high side for boost with the stock ignition. The problems remains and is completely unchanged with the ignition installed.
- I turned off the PMS control to see if it was causing the problems since I had standalone mode kicking on at 2500 RPM. The problem remained.
- With standalone mode on with the PMS, I pulled timing out slowly as the RPM's increased but the issue remained.
Things I want to try:
- I am waiting on the new Pro-M company to hurry up and get caught up with my order I placed a month ago to install the 80mm MAF. I have 42# injectors waiting to go on that match the new MAF's calibration. I will remove the FMU once the new MAF and injectors go in.
- I have a Kirban adjustable fuel pressure regulator and fuel pressure gauge to install. Although I do not think it will help, I planned on installing it when I did the injectors.
- I have a 255lph high pressure Walbro fuel pump waiting to go in. I have not had time to put this in. Part of me thinks that with the new pump it could correct a lean fuel problem that may be happening even though this kit is supposed to run fine with the stock pump.
So, does anyone think my ideas above will help or do you have any other things that I should try to get this running? Last week was hell and I now have less than one week to get this running for a dyno session at my college's car show on Saturday April 1.
Thanks in advance for any input on this problem.
