I had to buy the pulley. Mine came with a 3.25 but there was no way I was running that with a gen 2 and stock bottom end. That pulley should be good for 3 psi over the 3.625 which would ballpark at 48 more hp. That would put me at 480+ on this dyno. For reference a stock 5 speed s197 put down 249rwhp yesterday on this dyno.
Over the winter my plan is to build a shortblock and still keep it under 500rwhp. Too many problems come with power, I anticipate my next weak link will be the input shaft to the tranny. It's rumored that Tremec is coming out with a hardened 10 spline soon. If that's available by the time I do the shortblock it will be done while the motor is out.
First congrats on the numbers...very safe IMO and the A/F ratio is perfect. My timing on the Gen1 at 10.9 (11 psi) was set max at WOT of either 17 deg or 19 deg....but that is NOT much timing anyway so there is much room for growth (should you want too).
If your going to replace your trans spline input wouldn't it be better to just go to the hardend 26 spline input? Since the tranny is out and all? That would require a 26 spline clutch though and I know your clutch is new isn't it? Just thinking and typing anyway...So many mods and so little money....I want to do all of it together so when the motor gets pulled I will upgrade the trans and put in the twin disk clutch and one piece DS....etc etc...

I have the same size pulley as you Moose (when new the 3.375) and its a Gen1 but both of us had our Whipples a good period of time before many others on this forum....you and Hammeron IMO were one of the first MF.com members with the Whipple and on a S197 (from this forum and a regular poster too)......dont quote me people....

I wish I could remember where I read it. What I had read was that Tremec was coming out with a 10 spline that is as strong as the 26 and it was supposed to be out by the end of summer. Perhaps it was just another internet rumor.

Anyway, good numbers for 3.6 inch pulley. Next take it to the track.
Took it to the track today. This is the best timeslip. It seemed that no matter what I messed up some part of every run. Tirespin, missing shifts, early shifts, slow shifts. I think a hurst shifter can only be shifted so fast. Eight runs were in the 12's, 4 weren't. Speeds were pretty consistant and towards the end so were the times but it's real easy to blow the whole run on one mistake.

That ain't bad, better than me. Take it back when the weather is cooler.
