Belt tension

MiradaMegaCab said

Im running the stock mechanical fan. The stock radiator did fit but I upgraded to a larger aftermarket aluminum one.

Your upper pulley looks small. While a smaller pulley adds boost, it can lead to belt slip due to less belt wrap.
I tend to collapse the tensioners spring in an effort to provide max belt tension.
Just be sure to have 1/2" play left on the tensioner for thermal expansion.

You should check out 'MoparDude318' threads in the forced induction section, alot of good tech on radiator/ fan clearence issues. A shorter snout might help you out.

Thank you. My mechanical fan hits the pully tensioner about a half an inch. I'm not against getting a electric fan I was just hopeing to try it out this weekend. I guess I will order a fan. I was going to put my high flow thermostat in but it looks like it's to big. Do you have to run a certain style of thermostat? The guy I got this set up from said he ran a mechanical gauge in the car to see the temperature. I am wondering if he ran a thermostat. As there was'nt one under the neck when I checked it out.
I did'nt measure the top pully but the bottom pully is a 6inch pully, the fella that had it before said he had 5lbs of boost the way it's set up. I don't know... I did buy a boost gauge from summit and was going to install it, but when I opened it up there was'nt anything in the package but a gauge. I called summit and they said they would put the stuff in the mail, it came as a extra kit and they missed it when I was ordering it so they said it was on them.
I will try and look of mopardude318 radiator stuff, thanks.
