Can someone please post the # for the gatorback belt for a 2.87 pulley. I just bolted my blower up and the one i just bought seems a bit long. I looked in the stickies but could only find the gates #

 

Part # 4060690 Metric Part # 6PK1755

the numbers are similar, both have the lengths in them.

 

thanks guys

 

I use the #4060690 with my 3.125"....its alittle pain to get around the pulley, but once its on, its still needs tightening so its fine

how long have you had the 2.87 pulley? and are you still on stock tranny, aside from vb mod?

 

i just put it on this week but haven't driven the car yet due to installs of other stuff. I can't wait to feel it , i hear its a real kick in the pants . Yea i am still on stock tranny though

 

i just finished rebuilding my tranny, i got my parts from maximum tuning, i got vb mod stage 2 torque convertor with a 3500rpm stall and a graphite clutch kit, when i put my 2.87 pulley on it was like night and day, the belt was real tight though i had to spin the crank to get the belt to fit. but thats better than loose

my stock tranny lasted 1000 or less miles on the 2.87

 

What pulley did you have before the 2.87? Also how much did the tranny parts cost?

 

about 1500 and i had the stock pulley 3.6 i think, i'm at 11psi with new 2.87 pulley

 

Sounds like you got belt slippage you should be making more than 11psi. I am making 9.5psi with 2.87 intercooled which is a 4 psi loss!--I'm working on my piping design!

 

Matt is correct. You have my set-up and the Gates part # is 4060690 (6Pk1755)

 

i don't think it's belt slipage it may be my guage. i dynoed at 298.6 hp and 251.2 tq running rich and on bad tranny, i mean 1 week after dyno my tranny went, and all the steels in third gear were warped and overheated.
