Thanks for the heads up guys I appreciate everyone's input. You guys think 17% od is too much for a late model? It's has very minor porting done to it. I've heard people running 15-20 od with a fmic and they were ok when it came to the heat being generated but maybe that was all hear say?
I wouldnt do that... again lol...
Its not that the blower wont take the abuse , however there is way more than just the blower to make that amount of Overdrive useful
kevin L ran around 30% on his s port
However in ur situation
1 15% OD on a latemodel generates
19psi-20psi
2 20psi is about danger zone on pump gas especially if not tuned correctly and even worse if u are running nitrous things can go wrong fast
3. If u have a stock top end and cam you are only wasting more HP by turning the blower that fast
u need heads a cam
Keep in mind parasitic losses can never be re gained with cooling
theres a big difference
How i am telling u this is because i did it without the nitrous and it was no bueno sure it made decent pulls and felt strong had about every bolt on there is
but it was not good for the engine
another thing is you better use ARP studs or u will be re doing a headgasket job soon
and the 42lb injectors may run out of steam sooner or later if u want much more power
For your application
how about you try
a 10% JS
put on ur fmic
ur exhaust , port ur manifolds as well and start there
also make sure u have a good tune contact Xr7dave for some tuning if u havent already
If that is running well
then try out the 50 shot
And when all that is dialed in correctly then you can move up and enlarge the intake , thing is the stock inlet and tb are too small and starve the blower from air especially if u want to spin it much faster than stock
