Default Holley 90mm TB?

Not the usual "how is it" post. I'm just wondering where I can buy one of these damn things. Any sponsors sell them? Anyone know of anywhere else I can find one?

NLP ordered me a Holley 90mm one after my brand new FAST 90mm was sticking. The Holley 90mm TB is bearing driven and the response is awesome. It's a very nice piece:

Who is NLP? I already checked Summit, they don't carry them.

*edit* I just found them on Summit's site but only for LS2s. Will this be the same as LS1 application?

What type of intake are you putting it on. Because if it is a fast 90 than the ls2 style one will work because it is cable driven not drive by wire. And the fast 90 has bolt holes for both set-ups.

Yes, I was going to run a FAST with it. I guess it will work then. Thanks for the help.

What kind of gains can I expect with this 90/90 vs stock LS1 intake with a v3 cammed car?

I have never run a fast myself I have a single plane with an elbow. But The fast 90 is a far superior intake even to the LS6 . A freind of mine switched his ls6 intake to a fast 90 and he seems pretty happy with it.

the fast is a good intake, but you are going to get the benefit out of it with more power(ie big cam, nitrous, blower)...as for buying a 90mm holley tb, try here, scroll down

ls1speed has it for 20 bucks cheaper than Summit, sounds good to me.

I'm already running a cam, no plans for a blower, nitrous..maybe.

I'm just looking to break 410rwhp, then I'll start modding the suspension.

you can break 410hp easily with the ls6 intake, imo you dont need to break the bank for a intake on 410hp...i would invest in a new rearend tho

with a good tune and ls6 intake and p&p tb, you will be making more than 410...just depends on the tuner...but yeah, you should be making over 410hp for sure...upgrade your stall too man and you will be eating ppl at the track

Well, this is good to hear, cause just yesterday someone at work offered to sell me his intake off his vette. Guess I'll grab it from him.

I'll be getting a 3400 stall hopefully before years end (08).

good ****, you can delete egr/air as well, so buy the block off plates and get the coolant pipe kit for the ls6 intake...you can pick it up a ws6store.com or thunderracing.com
