4.0L Whipple Power!!
Any larger blower than the OEM 2.3TVS would/should precipitate an upgrade to a new set of forged steel connecting rods. Anyone ignoring this is not looking at the complete picture and their engine will be a ticking time-bomb..... unless of course you choose to limit the blower speed/boost and engine speed to a meager 6,000 rpms. That of course begs the question why bother to install a larger blower than the TVS if you are not going to use it to its full potential for fear of OEM rod failure?
2.9 Whipple/ 2.8KB at same boost as a 10-15% OD TVS will give +750 RWP on 93 tune with correct supporting mods and ias long as you do not knock the motor should be fine up to 6500-7000 RPM.
Explain how a street car can put that much power to the ground?
If that is not enough you are building a race car so it should have a rod upgrade anyway.
Exactly, whats the point of a larger blower than the TVS unless you plan to race the car, if so new rods are/should be in order anyway.
The 2013's perform just like the 07-12's, except they make a few more ponies at the same boost level due to the higher compression and slightly larger displacement.

Already installed a Kenne Bell 2.8 on my 2013
18 lbs of boost on 93 octane net 760 RWHP through the KB Dual 75 MM Throttle Body.
Here's a link with data and results. Another phase of testing is in the works.

+1. I really think the simple bolt-ons (CAI, TB, pulley, tune) is going to do it for most current '13 owners. You have a stock car putting 600rwhp already and with simple mods you have a 700rwhp carepper:. With suspension (drag orientated) you have a decent 10 street car....all with the stock OEM blower:rolling:.
Thanks for all the feed back. I called Whipple last week to see what they had to say. Basically, they said that the 4.0 would be tooooo much without doing some engine upgrades before the Install. They also said if I went any larger than the blower that is on the car I would have to drop the engine an inch or do something with the hood as it sits up higher. Not sure what to make of that. :shrug:
