I'm getting ready to install my FAST 90mm Intake and TB and I just realized that the stock bellows are not going to fit on the TB. I'm going to be picking up a lid also so that needs to fit in the equation. Anyway and I'm wondering what other people are doing for a bellows? Is there a vendor out there that sells on, or a cheap work around? Also do these setups need a 90mm MAF? Any suggestions would be appreciated.

The SLP smooth bellows will work on a 90mm throttle body. Hope this helps.

An LS6 85 mm MAF makes sense. An LS1 75 mm MAF would not.

Have to take a look at it again and see about the stock one for now. Would really like to get this stuff on the car this weekend. Thanks for all the input.

did it bend up though. I dont know what kind of bellow I have but I have a godo bulge in it right before the TB. Id like to get something that is 85mm to 90mm. Where can I get that.

The SLP smoth bellows does bend up to meet the lid.

?? The SLP bellows is the only bellows with a bend in it. It meets the lid and works fine if you havent trimmed to much off it already

Whats the least restricting bellow for a 90/90 setup

SLP is the only real bellow, All the others are either a plumbing part or silicone ricer part. The SLP has a woven reinforcment and wont wilt under heat and pressure. So IMO the SLP is the only real bellow and pro'lly offers the best airflow no matter the condition. Has it ever been proven? I dont think so. Its just my opinion.

and it clears the 90mm just as easy as the 78mm ?

You need to push it over the 90 same as the 78. Maybe it takes a little more force over the 90, not sure, but its what I'm using and I didnt have to heat it up or boil it or anything stupid like that. There are subtle differences. The bellow has notches in it for various obtrusions from the 78 that the 90 doesnt have but it works fine. Trust me. I dont work for SLP and have nothing to gain from telling you this.

Others may disagree how ever and say the ferno or silicone ricer hose is fine.,Its your decision.

All I'm saying is the SLP works great for me. I had it with the 78 and now I have a 90 and still using the same one. I had it for a dual nozzle n2o kit that I'm converting to a plate system so I used gorilla tape on the two holes..lol works great.

Ya, Im not a fan of SLP, but I am a fan of whatever works best.

I went to extremepsi.com and ordered a 4" id silicone hose. It comes in 12" section and is about $30.00 plus shipping. Just cut it to the length you need. A lot better then trying to make the stock accordian bellow to fit and will have some more bling factor.
