So I tried doing some searching on here regarding this larger throttle body (when compared to the L&M 82mm) and couldn't find anything; So i'm gonna start my own.

I asked BBK the other day when they would be releasing this throttle body and they told me it would be about 4-6 weeks on their website w/ the info and pricing. I don't know about the rest of you, but I will definitely be checking this out. here's a youtube clip of the install and dyno.

What else have you done to the car?

 

Right now I have the steeda CAI+tune, and cat back system from heartthrob is on the way. Ohh and a jlt oil seperator but I don't think I've had as much caught as others claim. I'm in california so I have to play it safe with which mods I put on. Once I move duty stations I'm gonna register it in illinois and go w/ LT headers, O/R h-pipe, and would love to get cams and heads. Along with various others on the wish list.

 

that is cool its coming out. But im not a fan of anything BBK

 

Why not? Personal preference or bad experience. Ill admit I was/am still weary of em.

 

Anyone know the ID of the stock intake manifold at the throttle body opening, or the boss intake manifold?

 

Bbk's throttle body's are mediocre at best. I had the tb/plenum combo on my 2v and the stocker performed better. I eventually acquired an Accufab 70 mm tb and professional products plenum and couldn't be happier. Performance improved enough to really feel it. Accufab ftw

+1. Accufab is very HQ

 

im not saying its bad. I just always thought they were on the lower end of quality. Stuff always looks cheap

 

I agree. But I would say bbk is junk. I have had many of there tb's only to replace them with accufabs. I would like a bigger tb if the gains are there though.

 

A going to big will affect the velocity of the incoming air charge. There is a balance. On my 2v 70mm is perfect. That 78 I had cost me bottom end torque. It actually bogged out under 3000 rpm.

 

Good point about air velocity. Would it also be safe to say that if its bigger than the intake manifold it won't be adding more air than what the manifold will allow?

 

Agreed. I had the Accufab 70mm TB/Plenum on my 2003 GT and loved it.

 

BBK is crap, but you will find people out there who will tell you otherwise. These are the people you want to avoid when seeking advice.

I asked which mods you had, because I think there are more important bang for your buck mods to do before the throttle body would be worth the investment.

 

So what else would you suggest, keep in mind I still have to keep CA emmisions in mind.

 

I'd suggest not worrying about CA emissions until smog time.

Get the off road x, a Boss Manifold, by then an electric water pump should be out. I hear Meziere is almost done with theirs. Then after that, consider the L&M throttle body.

Those are my suggestions.

 

I'm actually wondering if underdrive pulleys will be out soon? I'm still not sold on an x-pipe, but offroad h would be a possibility. The electric water pumps from what I've read aren't really suited for prolonged use, has anyone had any problems from using them on a daily driver type application? And an aluminum drive shaft or carbon fiber depending on price.

 

My still-unaswered question is, how will the larger throat affect low-end performance given a Bama tune and Airaid CAI? Not going with Boss manifold.

 

i would not change anything with out getting it retuned for your throttle body.

 

Does that make sense to anybody else or am I having a mini-stroke?
