For next year I want to do a pulley swap on my stock eaton. I've been doing some research and descided to go with a 2.8 pulley with a 90 mm aux. pulley, jlt cai. and tune. I already have flowmasters and bassani o/r xpipe on it. My question would be what kind of numbers can I expect with this combo. Also would upgrading my heat exchanger help these numbers?

You're probably looking at around 450rwhp, give or take. The heat exchanger won't make much of a difference, though many get them(like me..lol)

Agree, It's all in tune and how much timing they set up on top, You'll see 14-15lbs. of boost and anywhere from 438 to 469 rwhp. good luck on the pulley swap and keep us updated

get new throttle body instead of heat exchanger. nite/day difference in throttle response and good for a few more ponies

IMO T/B's are hardly worth the trouble, unless they are a restriction. They stick, bind, cause idle problems ect. True, throttle response seems improved, but it's actually because the cam ratio on the aftermarket is different than the stock T/B. Never seen a before/after of a T/B install, so I cannot comment on gains.

Funny deal is I've had THREE different Accuffab's tb, on My Eaton set-up first and now my Whipple Termi without one single problem, most that do have problems, are the people that don't know How to Set them up, I use this statement loosely and to say there not worth the trouble, well that a different story that I'm just not going to get into :smash:

Ok, well your lucky IMO. Mine has been adjusted CORRECTLY and still does funny things when hot. I know there have been many with and without probles, just saying untill the T/B is a restriction, spend money elsewhere.

bbk is junk. accufab & their port matched plenum here and no problems with cruise control (typical problem with them). billetflow is a nice piece too and you can get engraving/colors on it.

yes tim you need a re-tune.

go with accufab or bf
