im stuck on either a bbk with a 85mm throttle body or a victor jr. with a 90mm throttle body. its going on a 5.3 with z06 heads, 02 ls6 cam, 3600 converter. all otherwise stock.

BBk are good and decent priced, victor jr is more with the elbow and throttle body.

Why not a ls6, cheap and work well.

well i did think about an ls6 but what kind of hp differences would i see. the bbk intake in some dyno's i seen made more hp than the ls6.

There cheap and proven above 800rwhp so unless you just want it for looks or a few more horses then go for it but I dont think its really worth the extra dough till you have better heads for flow and a larger cam. Just my 0.02

yeah. i know the ls6 makes good power but ive personally seen switching from a stock ls6 with a p&p throttle body to a fast 90/90 he gained 15 hp and 78 ftlb of torque. but the fast is just too expensive. the bbk is 399.99 the fast is 829.99 i can see spending over 400 for 15 extra hp. but would the victor jr. be too much for my 5.3?

the BBK intake is the way to go! good luck your build. PS use the best valve
spring you can $get$

Dont these hold alot of unwanted heat when compared to a LS6 intake?and really dont flow much better either (From what ive read on here anyways)?

We dont talk about heat soak in this section, lol. I personally would have gone BBK over ls6. They look better and come with rails and brand new for almost as much as a used ls6.

Why not just a stock ls1 intake? That is what I got and am at 550+ rwhp through a BIG LOOSE stall in my rx7, went 144.7mph also.

LS6 hands down.

That ain't no ****, that maybe the only post I have read in this section even mentioning it.


Go with either one. If it doesn't make the power you want just add another pound to it.

Show dyno grpahs to prove those results.

I find that so hard to believe on a boost application. The stock LS6 intake and TB are more than adequate for all but the most extreme builds.

And IMO its senseless having a TB larger than your IC plumbing..

ok. so now its either the ls6 or bbk.

bob from EPP gained a good bit of power swapping to a fast 90 on a blower setup even with lower boost level.

if you run a pipe the same size as the TB youll see benefits from it not just in airflow but drop in IATs. Same theory as in sizing exhaust but its the opposite. Exhaust you want to keep the exhaust hot to help it travel to larger and it cools off to fast. With a larger IC pipe you drop IATs but slow down flow but it still is going to the intake.
