Hello Folks,

Has anyone used the BBK SSI- Series Intake Manifold - LS-1 (Titanium) With 80mm Electronic Control Throttle Body.

The model is 5006

It claims to 18-24hp

What do you guys think?

Here is the link

Most anyone on this forum will tell you not to go with that intake. I agree for the most part. Though I do believe some power can be made, it will only be a little bit. This is because of "heat soak". The stock intakes are plastic and do not heat the air like a metal intake would. That is why everyone on a budget goes with an LS6 intake, or those going more all out choose a FAST intake. Keeping the plastic style is the best way to go. Avoids heat soak, keeps the weight down, and both the LS6 and the FAST intakes are known to have an incredible design in the way they flow. There are also many experienced porters for FAST intakes now.

I installed the bbk intake manifold with electronic throttle body now rpms won't go less than 3000rpms, any suggestions?? Please help, I should have done my homework before doing this

you probably have a massive vacuum leak somewhere.

Where do I look for vacuum leak?

It's been awhile since I put my BBK intake on but if you left off a vacuum line or if maybe you left out a intake gasket (they are individual). I like the intake by the way, looks cool and performs better....

I didnt put any gasket sealer could that be the problem? All the gaskets are there though, thank you

As has been stated, probably not worth the extra $$$ over an LS6 intake performance wise, and definitely not worth the $$$ performance wise when you can get an LSX intake.

That being said, if you're also into show and not just go, a BBK or other polished aluminum intake would certainly compliment other polished pieces like a throttle body, or a polished supercharger and polished tubing. And the hit to performance via heat-soak wouldn't exactly be tremendous unless you frequent the strip often and are after every last .10

I like that u like them cause im hoping I c an get it running right can't install the factory one cause of the damage it had, originally went after knock sensor and found the intake had damage, but I won't be able to return the bbk intake and tb, just don't know where to start

The bbk intake is based on ls1 intake design.
ex: it has a giant hole right in front for egr on pre 2001 models. You have to use the supplied gasket and block off plate. Plate alone wont do it.

You shouldn't need sealeant on any intake gaskets. Make sure all vac hoses are secure. You can hear a vaccum leak that big easy...even over cam and exhaust.

Heat soak is a minimal issue IMO. Air moves too fast to heat soak much. Also, aluminum intakes don't blow apart with nitrous backfires. So if you run or plan NOS, I always recommend aluminum over composite

Thanks a lot, I ill check everything again, I don't remember receiving a gasket for egr, but will double check, I appreciate your help,

Went from not going Below 3000rpm to won't stay running any more, I do hear popping coming out of maybe throttle body, I even went back to stock throttle body but left the intake mmanifold on with the same results, any ideas? Thanks
