so i found a dyno graph of a heads cam 5.3 going from a truck intake manifold to a stock fast 92mm. it picked up 34 hp!!!!!!!! it went from

441hp to 475hp (fly wheel horsepower)


impressive right? im thinking not. i did a little math and averaged the HP between 3000 rpm and 6400 rpm.

the results:

truck intake:
avg HP across band = 351.94
avg tq across band = 388.87

fast 92mm
avg HP across band = 347
avg TQ across band = 386.75

so in average you actually lose 4hp and only gain 2tq.


here is the article to read for yourself.

i know i have more cubes but it as of right now the fast 92 just looks like it gains you peak numbers at the loss of bottom end. a combination that probably works awesome on a light *** camaro. im atleast 1000 lbs heavier than your avg camaro and i need that down low torque! not huge top end torque and HP. im still looking for more information if anyone has any

is the nnbs intake the same as the ls2 intake with the 90mm throttle body? if so, NO.

Im pretty sure the nnbs intake is the same thing as the tbss intake, which is way better than the truck intake. Pewter53 said he got a really nice gain going to the tbss intake from the truck intaek

the hotrods over on tech have proven the ls6 intake is better than the 90mm truck intake over and over and over and over. they beat it to death over there haha. and to be honest i think the truck intake is better suited for us than the ls6 intake.

I thought they compared the LS6 intake (78mm) versuses the Car LS2 intake (90mm), not the LS2/NNBS Truck (87mm) intake... I don't think i have seen anyone test the NNBS (87mm)truck intake..


I am not sure if the SSR intake is teh exact same as teh NNBS intake... I thought the SSR intake was a normal truck intake with a 90mm opening... I maybe wrong thou...
