20 mph is not hard to believe at all. I gained 15 mph on a single engine setup with a Whipple on a stock carbed 454!!!!

Those look like 3.3 liter so 775 HP vs. 525 HP stock should do the trick! Clean looking install. I see the speedo, what's the boost gauge saying?

Boost read about 6.5

That looks like a hell of an install. Where are you located? Do you build custom motors?
