1- why did you post this in power adder?

2- the car should run better then 13's assuming that everything you have now is well matched...

don't take this the wrong way. Im just looking to help keep your thread from being locked by keeping it power adder oriented and by answering our request. Turbos, centrifugals, and roots superchargers all are safe when used safely and in moderation, that goes for THIS as well. If you get this you might want to consider one of THESE just for it separately with a regulator and leave the pump you have now for the carb by itself.

Maybe try general engine...

But like I said, that assuming that everything is done right you should be going a lot faster then 13's... I've run a 13.5@100 with essentially a stock L98 with no real changes besides a cold air and cat back...

You've got a somewhat modified engine, converter, gears... You should be going faster.
