FAST 78mm vs LS6
FAST 78mm vs LS6 Search is currently being work on by Brians so I really can't use it right now.
I'm wondering how the FAST 78mm intake compares to the LS6. I don't care about the cost differences and would just like to know how much extra hp you can pick up from the FAST over the LS6. (I currently have the LS1 intake so I need a new one no matter what).
The car has all the bolton's and a cam. The cam's intake/duration are both in the 230's so it's nothing crazy but still a strong cam.
Again I don't care about the price differences(I found a great deal on a brand new FAST78mm so the price isn't that big of a difference) and I don't need a 90mm by any means yet and honestly never will as I don't need to make tons of power to enjoy my car.

honestly id buy the ls6 if cheaper than the 78 fast but if they are almost the same go with the fast 78. if u were going to pay full price for the fast id go with the 90.

I'm just curious as to what kind of gains there would be with the 78 over the LS6 on a 231/239 type cam.
yeah now that u said that fast 78 if u can get that good of a deal on it def the 78 then ur right u could always go back to sell it and it will hold its value more than the ls6. as far as gains not much would be my guess maybe 4 or 5 hp over the ls6 with a big if that.
Alright well I just gave the guy the money for the intake.
I'm giving my already ported/polished tb to http://www.performancethrottlebodies.com/ to take a look at and see if he can do anything else to it to make it better.

As for my gains, I'm not sure of the question. As I posted I gained 10 HP but lost 7 in the Tq dept. The only changes I made were the FAST and a ported stock TB.
