Need 2.9 Whipple upgrade help

[FastOldGuy52]

I think I want to run a 3' upper with a 10% overdrive lower pulley on a 93 octane/torco tune, on my 2.9 Whipple.

1. Is this possible
2. What are the best pulleys to use and where can I find them.
3. What kind of gain could be expected over stock 3.25 pulley and stock lower. [18psi now]
4. About how many horse power increase could be expected [712/626 on 93 and torko now.]

Thanks in advance

Hey OldGuy! Sorry I had to say it! :lol:

PM Me for my number and I can tell you all about it tomorrow.

I ran a 3' upper with a 10% O/D on my 2.9L with out one single problem. You'll be at about 21.5lbs of boost. Horse power is only going to go up a little but torque is going to be crazy. Here's my dyno graph with the 3" upper and 10% lower. I have a 3.00 and a 2.875 pulley for sale if your interested.

I see Chris's dyno #'s are STD, do both have your dyno#'s in SAE?
