Hey Guys I have the BBK SSI Intake and 80MM throttle body on my truck now.
Mods:
2001 5.3L engine
BBK SSI Intake Manifold
Comp cams 216/220 .525/.532 114LSA
Comp Cams 918's
Comp Cams Hardened push tubes.
Custom cold air intake
Sanderson 1.5/8" primary short tube headers.
Custom 2.5" Y-pipe into single 3.5" through dynomax bullet and
flowmaster 40 series.
MSD wires, NGK TR6 plugs
ASP Underdrive pullies.
ARP Rod Bolts

This setup made 325HP and 327TQ Naturally Aspirated. Do you guys think on this mild setup I would benafit at all going to the Fast 90/90 Combo?

Thanks

 

I wouldn't think so. Seems like that setup should be making a little more power than that.

 

Yes as the 90/90 would also leave you more room to grow.

 

fast 90/90 works well with nitrous also.

 

with the amount of cubes you have i would go with a slightly bigger cam and do heads to take advantage of the manifold. otherwise youll have to rev more with the massive 90mm on that small motor.

 

IF I do upgrade to the 90/90 it will also get 1.85 rockers at the same time.

 

screw 90/90 dont half *** it, get a carbed intake drilled for injectors. it is the best.

 

This is the first time i've heard of someone using a BBK manifold, how does it stack up to other aftermarkets? Similar gains as an LS6 or ported LS6?

 

It is similar to an LS6. there are a few people out there using them. I have sold 3-4 of them while working at a speedshop. It would be worth it if you can sell the BBK one.

 

The BBK is a great intake, I chose it in-case of a Nitrous backfire. When I installed it I replaced a stock LS1 manifold and gained 3-MPH at the track.

Thanks to all for the input.

ANyone Else?

 

TTT, I have been runing a bbk ssi intake. Ive been wondering if i wasted the money or not..

98 camaro With long tubes, BBk intake, K&n Fipk, ORY, and SLP LM I made 310 hp 310 tq. On a Built 4l60e, with a tci 3000. This week it will be tuned and ran at the track.

Every one at the dyno day said for a untuned, unlocked 98... 310 is not bad at all..

Opinions?
