Re: Arrington 90mm throttle body

no idea.....have a look at thefastman.com His TB's are a work of art and are CNC machined and gets a new blade to fit the new size. Ive had 4-5 of his TBs and all have been perfect. Ive never heard of Moe's.

Re: Arrington 90mm throttle body

Moes is far more popular with the Ram crowd. You can easily google to check reviews.

Re: Arrington 90mm throttle body

Do these TB effect idle RPM?

Also is MPG effected under normal driving conditions

Re: Arrington 90mm throttle body

I use the Modern Muscle units and sell them on my site. I've got my tunes set to run with these very well. Put my tune with this tb and it'll respond very nicely. you won't be disappointed. Not only is there a hp gain (those many say there isn't and its mostly true for stock pcm's or even the preloaded tunes) but there is a nice drive ability increase.

This dyno is of an 87mm unit on a '14 AWD 5.7 GC but I generally like the 85's on the 5.7 configs. I've got 3.6 throttle body's as well

I know Moe's 87mm is just a stock throttlebody CNC ported... Now, I know MM's says its an 87mm CNC ported also, but is it a stock TB also or is there more of a difference.

Re: Arrington 90mm throttle body

They are stock units that are put into a CNC cutter. Be cautious of the straight bore designs on the larger units. I had a BBK 85mm straight bore on my wifes '10 5.7 challenger for years. Swapped it to the Modern Muscle 85mm tb two weeks ago on the dyno and picked up another 6 to 10 hp and tq over top of the BBK gains I had already had. Unless you port your intake manifold, anything over the 83mm range on the back side will be larger than the intake and disrupt flow

Hemifever,
Looks like a fairly substantial tq increase down low were its needed for daily driving! Just curious why you prefer the 85mm over the 87mm? Also, did you happen to get a completely stock dyno pull, stock tune, no mods?
Thanks
