Nice numbers have you ran it at the track?

My experience with the 4.5 Whipple…. One of the single most effective things you can do with that supercharger is plenum spacers. I made 1200 rwhp five years ago with that 4.5. Car ran 8.7 at 4500 lbs with that combo. I was running a +10 at the crank with a 4.0 Griptec. One of the issues that supercharger has is belt control and it needs one of the high tension aftermarket belt tensioners to do that at the higher boost levels. I would also recommend not going smaller than the 4.0 on the supercharger. A icebox/chiller to reduce your IAT will also be a huge benefit when the boost goes up. That is not a cool running supercharger compared to the new gen Whipples. Also…. I would increase your injector with those changes. 1700’s at least.
