I figured I should post this here: As far as exhaust size is concerned, what size exhaust would be ideal for a centrifugal supercharger?

As i under stand it 2.5" should be fine. THe idea of a 3"+ on turbo apps is that it creates a low pressure area. The high pressure gases on the exhaust manifold side then rush over the turbines to the low pressure side (Highs to Lows always, basic physics) which moves more air faster over the turbine blades themselves (turbine blades are essential small lift producing devices) spooling it up faster.
I'm guessing 2.5 should be fine for a SC application but maybe a 2.75 would be better? Might have more to do with how much power you are trying to make and thus how much fuel you'll be burning. More fuel burned would equal more exhaust gas to flow, no? |

If you base it on the 350Z type of Supercharger then you would be seeing ruffly 80-100whp with complimenting bolt-ons Exhaust TP Headers DAN

I have a concern and would love to get some of your opinions.... GTM and Stillen offer FI kits for the 350 that offer "mild" gains in the namesake of being "safe" GTM, for $8,000 offers 50 hp and 60 ft lbs of torque. I think Stillen stage one is about the same. Am I the only one that thinks this is REALLY steep for those gains.
In my opinion if Stillen is to come out with a FI Supercharger kit, the "safe" gains would have to be at least 75 whp and over 75 ft lbs of torque. And the price should be under $7500 all done....everything needed for a proper install and tune. I mean worst case scenario! Guys at Stillen can you comment on this logic? Anything with less gains or greater price would cause me any MANY others I know to be happy with our cars power or wait and buy our next car with more power from the factory. Maybe this is just a rant....thoughts???

But keep in mind.. we sold ALMOST NO stage 1 supercharger kits. That was a non-intercooled kit, and was purely for price. We didn't even offer them for later flavors of the VQ35. We'll have more details soon.. and the goal is all of the additional benefits.. CARB approval.. engine warranty.. bolt-on reliability.. all the good stuff.

supercharger and the warranty, thats about it. i dont find it reasonable to pay 7k for 75 hp and 75 trq if you think about it your spending 7000 dollars so shouldnt you get at least 150-200 hp? tt kits should go for 5-6k (if it gives you 300-350hp) but superchargers should go for 3-4k (if it gives you 200-250hp) that would be a reasonable price for me. another thing is it would be the first supercharger out so there is no doubt that its going to cost an arm and a leg. |
