My current Holley 90mm TB is 3" in depth from where the bellow butts up against the TB on the front to where it mounts to the intake. The problem is that I plan on installing a 85mm MAFS which will give me even less room between the MAfs outlet and the TB inlet then I have now, this is with using a SLP lid which I want to stick with if all possible.

So if you have a 90-92mmTB, preferably a NW 92tb or FAST 92tb can you measure your depth as I stated above so I can know if it's worth going to another TB to avoid clearance issues.



Thanks, Ron

Come on! Are your guys telling me that no one with a NW or FAST 92 throttle body has a tape measure......? .....

I've got a NW 92. What exact measurement do you need? From the lip of the inlet to the body itself?
Edit- I got it. Hang on a sec

Alright.

2" on the NW92 from where it mounts to my FAST's flange to where it butts my coupler/bellows. It's pretty thin.
The mouth itself is 1 1/8" long.

Wow, that's a whole inch shorter then my Holley 90 TB (in photo)!
Thanks for the info!
So, I guess I'll be having a Holly 90 TB for sale soon.

You have options before having to get a new TB.

The stock bellows will fit with that TB, the 85 MAF and lid.

You can trim the SLP bellows to make them fit.

I run the Holly TB with the 85 MAF, and thats how I got around the issues.

I already had the slp bellow trimmed as short as I could with that setup shown above, along with grinding the nubs off the inlet and outlet of the factory mafs ends so the it could go further into the lid and the bellow could slide further on to the mafs outlet. I believe the problem stemmed from the snout position on my TPIS 90 intake being slightly more forward and angled differently, and the added length of the Holley 90TB and its mouth being angled slightly downward compounded the issue. Believe me I tried even using the stock bellow (with the ends trimmed slightly) with 85mm mafs and the Holley 90 and even that didn't work since the angle was to great and they were too close together.
Anyway thanks for the reply, I still appreciate it.
