Question Hella tempting.. fastman tb

I search and there are tons of 4.7 reviews, a few 6.1 reviews but no 5.7 specific reviews on dan's tb work.

I'm five minutes away from pulling the trigger, just wondering if anyone has any experience with the product/company? Thanks!

Looks like a great deal that's hard to pass up. Can anyone confirm MPG gains, too?

Re: Hella tempting.. fastman tb

Dan does do nice work. He knows what he's doing.

The Hemi does respond well to a larger TB. I'm hoping we will be on the dyno with a CNC'd 84mm FRP Hemi TB by the end of this month. Mileage is dependent on the user's driving style. I've only sold a few Hemi TBs (old 87mm taper-ported version), I dont recall if anyone said anything about mileage.

Other folks with the 3.7s and 4.7s have noted mileage improvements.

Re: Hella tempting.. fastman tb

But the site recommends the 80mm job as opposed to the 84mm job.. a) I only have bolt on mods and b) the 80mm job is $100 cheaper

Re: Hella tempting.. fastman tb

True. Yousmellfunny has I think a 85mm. Would 5mm make a difference? I'm sure 80mm's enough! I think it will be a nice improvement!

Yep.. I'm going to buy a new core in case I have warranty issues...

Re: Hella tempting.. fastman tb

5mm makes a huge difference especially with a nice engine like the 5.7

Re: Hella tempting.. fastman tb

The stock TB is 80mm.

We ran a test today, on a CAI, Catback, & tuned 6.1; a stock TB vs a Modern Muscle ported one. Lost 8hp and 7ft/lbs, despite cooler temps and 2.5 degrees less knock.

So you're saying "no" to a TB??

Re: Hella tempting.. fastman tb

You'd need a tune or get a diablo tuner or something in that nature to make sure of the more air.

Re: Hella tempting.. fastman tb

I have a Diablo canned tune.. I've been running the 87 tune lately b/c the 91 tune kept throwing a code (o2 sensor). It's not the gas I run Shell, 76 or Chevron all the time.
