Bigger TB's - Arrington & Fastman

Want a bigger Throttle Body so have been sussing out these two in particular , prefer a solid Billet at 87mm
Arrington do have a 90mm bigboy but from what I'm reading , that is probably going at it too hard

I am asking for a part number for both if anybody has gone & done this - be much obliged

Re: Bigger TB's - Arrington & Fastman

90 mm is to big. Just stick with the 85mm And you will be fine. Bbk arrington or Dans (fast man) and you will be good. Any of the true 85mm not the tapered ones will be good. The 90 you have to port your manifold to fit and unless you have other heavy mods its way to big

Re: Bigger TB's - Arrington & Fastman

There is also Modern Muscle Performance (MMP) which makes a polished version if you wanted some bling to go with with performance! Arrington can powder coat your TB black as well, costs $100 + price of TB.

You have options though, which is nice (alphabetical order):
Arrington-
84mm Billet- $550: Arrington Performance Billet 84mm Throttle Body - shopHEMI.com
87mm- $400: 2013 5.7 | 6.4L Jeep SRT CNC Ported Throttle Body 87mm - shopHEMI.com
88mm Billet- $550: Arrington Performance Billet 88mm Throttle Body - shopHEMI.com

BBK
Does NOT offer TBs that work on 2013+ 392 motors.

Fastman-
85mm > 81mm or 85mm > 84mm- $353 or $398, respectively: https://www.thefastman.com/throttlebodiesHemi.php

MMP
85mm- $380: https://www.modernmuscleperformance....Throttle-Body-
87mm- $390: https://www.modernmuscleperformance....Body-87mm-4251
87mm Polished- $450: https://www.modernmuscleperformance....Body-87mm-4251

Re: Bigger TB's - Arrington & Fastman

Although an order is given to Fastman and half a year passes, there is almost no exact reply.
When a reply came to me from Fastman, he had said that he will complete soon.
However,two months or more pass since then.

Did you notice a big difference with the fast man 87mm?

What other mods are you running?
