lordkevork Posted October 27, 2004 Report Share Posted October 27, 2004 (edited) Magnuson told me that if I use a 3.0 pulley it will harm the motor but not the supercharger. What is everyones experience with pulley swaps and the radix? Just curious...

rdss Posted October 27, 2004 Report Share Posted October 27, 2004 I think alot of people are running the 2.9 with no problems. Quote Link to comment Share on other sites More sharing options...
styleandspeed Posted October 27, 2004 Report Share Posted October 27, 2004 As long as you are tuned it will not hurt the motor. Aaron Quote Link to comment Share on other sites More sharing options...
slimsoftball Posted October 27, 2004 Report Share Posted October 27, 2004 I got about 5000 miles under my belt with a 2.75. Tuned perfectly by Allen I might add. I have a little slippage when I really get on it, which isn't very often, but I am getting ready to go down another 1/2 inch in belt size.

How did the cam effect it? Quote Link to comment Share on other sites More sharing options...
slimsoftball Posted October 27, 2004 Report Share Posted October 27, 2004 I am only getting a little over 8.5. I am pretty sure the cam is causing me to lose some boost. I will be calling FMS pretty soon to see what kind of specs they think would work well with boost. Any suggestions? Quote Link to comment Share on other sites More sharing options...

styleandspeed Posted October 28, 2004 Report Share Posted October 28, 2004 Believe it or not the 02-up LS6 cam is a really good blower cam. Has -24* overlap which is good for boost. I don't know if I would spin it up as high as the powerband of the z06 cam will allow with that 2.75" pulley though. Might be a bit too much for the blower.

Would have made too much sense to just PM him and ask I guess. <{POST_SNAPBACK}> What makes you think I would have answered? It was a couple of cams ago, so the specs are a little fuzzy. I'm not 100% sure, but I believe it was a 217/228 .565/.585 114 +4. I can call and ask Candy if you like. I could talk to her all day. I didn't have the problem of bleeding boost up top with that cam. It was there a little, but only about .2 or so. Does your boost build real quick then peak and drop off pretty fast, just before it starts to build up again? Happens around the shift?
