Anyone running 2 pulleys? Did you lower shift points so as not to grenade your SC? If so, to what RPM? How could I contact a purveyor? Any other admonishments.....Ken

 

I have both upper and lower and I'm shifting at 5400. I have shifted it at around 5600, but my times seem to be better at 5400.

 

Johnny Lightning is running two pulleys.....

Ken..........you wouldn't be trying to go faster than me now..........woodja?

 

I've had JL's lower pulley and Lightning Forces upper pulley for about 2K miles so far no problems. I'm not a grandpa driver and get it up to 140+ everyday. Most every week I go to the track. I try to street race as much as I can, even though it seems no one wants to. My truck is a daily driver until I get my other truck back. I think I would be able to hear a bearing or something going out because I can turn off my electric fans and listen. I had JL reprogram the shifts. I just let him decide where to have it shift at. He knows a lot better than me.
