D1 PROCHARGER VS F1a PROCHARGER....??
wanted to kno what was the horsepower difference between these to blowers at same psi, same mods, and same motor....?? would a D1 with a 50 equal out with the F1a both on the same psi...??

Its really not a question of better overall as it really depends on the setup. Motor size, HP, goals, because it plays into which one fits your needs best. On big CI setups 408 or larger the F series blowers are going to be a little more efficient not just an F1R mainly because of the step up ratios. But that is just a quick run down of it there is alot more to it than that. Hope that gives you a little better insight.

Lots of info on this topic to read into the wee hours of the morning. I think I've read it all, twice. In short, unless you have a built motor you have to run a D1. Without some tricks, an F1 can't be pullied down enough to run at a safe level on a stock short block.
KP ran low 9's with a D1/346 combo. He went to an F1 and didn't gain much. I run a D1 and love it, but if I was building a big cube motor I'd probably run an F1.

there is more torque with a stroker. base you decistion on the CI of you engine. also depends on your goals tell us what your goals are and we will help you out. It comes up every week there is tons of info if you use the search button.
Let us know what your goals are and we will help you out from there

It comes down to CFM. Like stated the F series blowers have a more agressive step up rate, can be spun to a higher rpm and flow more CFM all around. For example, if your motor with a d1 is making 600hp@ 13psi, it may only take the F series 8 or 9 psi to make the same power. The F series are better for larger engines seeing as how the flow more air. With larger engines, you will max out a D1 sooner and it wont make as much boost before hitting your blower rpm max. I've seen D1's on 402's plus and they still did dam well and made 700+ easy. All in all get a F series blower if avaible lol Hope that helped.

A F1A will be a better choice for anything with more than 400 cubic inches. Not to take anything away from the D1 which is a great blower but the F1 will make more power and torque and a lower psi.

I mean I know itll run like hell with a D1, but a F1 would be better suited, plus be able to grow in the end.
Yea I know it all depends on goals which would be easier for us to give an opinion, heck I'm about run a D1sc on my vette with 416ci, but later upgrading to a larger F1 headunit

The D-1SC can make good power, but on a 400+ cubic inch engine I would go with an F-1A, as it won't have to be worked as hard as the D-1SC. Check out this LS2/402 with an F-1A. http://www.exoticperformanceplus.com...Car.php?car=29 Bob
