I went to RSI to dyno, great bunch of guys there. Let me ask this question........How many of you guys really see 14 and above PSI from a 2.80 pulley?????????? If you see more I would like for you to tell me where your gauge is hooked up and if you ever hooked up an external guage to check that reading. I have been looking at this for some time now and hear of people getting 16, 17, lbs of boost from a 2.80......we hooked up an external to mine today and the best it would read is 13-14 max and drop off...........so lets hear how others are getting that much boost. No flame intented just need info..........................
Do you have the Nitrous Pete dump valve mod yet? Just wondering....It does help, atleast it did with my setup, even before my JDM 6 lb lower. I have a JDM upper 2.80. I am getting 20 lbs of boost now with a drop to about 17. But the 20 holds up till the high 5000 rpm range. But from 2,500 to 5700 rpms..the boost is just awesome!!! Get that 6 lb lower...you will love it!
With my 2.80 I was getting 14 to 15 normally....on a nice cold day I would get 16
My recommendation is don't use the Gatorback because it may stick in the grooves of the pulley. I spoke to Reichard and he said only use standard style belts. The gatorback isn't going to do anything. Those idlers look great, I got the standard 90mm stock style one. My belts still slipped with that but the RR pulley completely eliminated the slip. I think the idlers may be a waste with that pulley. I'm going to test it soon.
