I finally have my truck where i want it went with the ARH fit great.
I put a smaller pulley in the back of my 2300 maggie got boost up to
8.8 or so with a 3.6 pulley in front now the other day i put on a 3.4 pulley my last and final one, was looking to get 10psi well i got 10.3 10.4 SO IM GOOD!!Sometimes when i get on it than let off i can here just a touch of a squeal ANYONE ELSE HAVE THAT!!!ALSO SEEMS LIKE SOMETIMES ITS AT A HIGHER BOOST THAT OTHER TIMES WITH EITHER PULLEY IS THAT KINDA NORMAL!!!My pulley aint that small in front and i have good belt wrap.NOW i do have the stock belt tensioner on the truck.The maggie has the manual one u slide and tighten but WONDERING if i should change the factory tensioner on truck?Also what belt do u guys run my gates green stripe was way to small so i bought just a cheap one from autozone but i dont see any dust at all..I DONT REALLY KNOW IF BELT IS SLIPPIN BUT have my doubts!!Is the GATOR BACK the way to go also do u wana use shortest belt possible?Thanks guys

 

You'd know if you had slippage by looking at a graph of the manifold pressure to rpm, and by obvious evidence like rubber dusting around the front brackets. Are you still 1:1 in the back, or did you overdrive it?

I've got a gatorback on mine with twin 100mm idlers, but that's only because I couldn't size a gates HD to fit. I might measure it by the time it needs replacing just to see if it's stretched.

About the tensioner, the one that's under the jackshaft, is it spring loaded?

 

I did over drive the back pulley just because my friend had a pulley for me it worked out great..The tensioner under the jack shaft is manual not spring loaded..

 

You should have a spring loaded tensioner, take a picture of your belt setup. You most likely are getting a bit of belt slip, If it squeals when you let off I bet the tensioner is nearing the end of its range of travel and slacking the belt a bit. The Maggie adjustable idler is not a tensioner, that is so you can fine tune the belt adjustment so that the tensioner is in the center point of travel.

 

You don't have to yell, capital letters is Internet yelling FYI.

 

Put some cogs on the rear of that bitch!

 

Mine slips when I let off from high rpm's. I'm running a 10% overdrive crank pulley and a 2.8" blower pulley on a front drive. It doesn't bother me though, I see it as stress release for the pulley/belt system under deceleration. Better a bit of slip than a broken part. It doesn't slip under acceleration, and that is the important thing.

 

its probably the clutch or lack of on the alternator.
