Since I have added another 25whp At least and should be crossing 830whp still on bolt ons with a jokerz ported stock blower and port methanol injection. I was only 1 tenth off the fastest zl1 heads and cam stock blower current record too. Shows the little 1.7 ltr that could when ifs ported by the best company in the business. I do believe this new setup is going to get me to bottom 9s and 148 plus mph. Car went 9.70@145 in the middle of summer on the old setup spinning and having to lift. So this summer should be interesting once I get it dialed back in on this new setup. I do know I make a whole lot of big blower combos and heads and cam cars scratch their head when comes to the power my car is making.
Funny now with the 2650s around whipple looks no better then a stock ported blower setup.

Interesting post. I think it’s safe to say a stock engine leaves a lot more on the table for a Whipple than it does for a stock blower. There are a number of Whipple builds over the years over 1000 RWHP. But even with a stock unopened LT4 and a Whipple (and no direct port methanol) has run 9.48 @ 147 (https://www.lsxmag.com/videos/drag-r...o-zl1-goes-9s/). Four MPH faster than yours, with less meth, is nothing to sneeze at IMO. And the heat soak issue of the stock blower is well documented, so I’d guess the Whipple (and of course 2650) would deliver better IATs on back to back runs in conditions your average Camaro driver would see (2000 DA, etc). I’d wager your direct port meth system probably kicks ass. Will you make me one?
