So what is this secret to converting a 950HP Holley for blow through use? SOME say it can be done in a matter of minutes. Spill it!

I sent my Pro-formed 750DP to Scott at SDCE and he set it up for $200. Slapped it on and drove the snot out of it.

There's a big difference between making a few adjustments to make it run well WOT on a dyno vs. making it a great street carb that returns decent mpg N/A as well as working under full boost WOT. Hangar18 seems to be one of the best from what I've read for DIY

I modified my 600DP. I have been getting great mileage with it, and I am not light on the throttle. The fuel consumption almost acts like it is n/a. grant it I have a stock sized cam, 8lbs boost going into a 383ci motor.

I'm going to convert my Mighty Demon 825 to E85 blow through in the next few weeks...

I'll put a post up when I'm done what it took to make it work, and how it goes...

Ditto. Nothing to it really, except for the fact that you gotta be willing to do alot of messing around, and in the end, its still gonna be finicky, like all carbs ever built.
