I think in another thread it was one of the last of the first generation whipples?    Nine -quick question what degree timing is your tune at now? Just curious ... I have the first gen whipple and running about 10.7 boost and 11.5 A/F at WOT and at 6000 rpms I was at 10.9 (pig rich) yeilding 454 RWHP in 93 degree heat and 60+ humidity in september. I had to get it retuned because of sputter on startup (only while cold) and the dyno at 69 degrees and 30% humidity yeilded 465 RWHP and the torque stayed the same at 440 RWTQ. I attribute that to the heavy 20's and the totally stock driveline. This year is the year of supproting mods like the 8-rib belt kit and thumper tensioner, one piece DS, new motor mounts and McLeod twin disk....than back to the dyno and she what happens.... (hopefully no "boom")     J

Did you get the second generation whipple?

Yes, it was the second to last 1st Gen shipped by whipple. I cannot recall exactly what my timing was set at. I'll have to get it from the computer when I go back on the 17th. All my info is saved, so I'll just have to look it up. My air/fuel stayed fairly steady at about 11.2 to 11.3, which is still to rich for me. I probably made slightly more boost than you due to my being at sea level. I already have the one piece driveshaft and a SPEC II, which may have attributed to my higher-than-average numbers. If you dynoed on those 20s, then you could probably have hit 5-10 more HP with a set of 17s. I'm also interested in the Thumper tensioner. I saw a picture of it on another forum and it is beautiful. Where can I buy it??
