VMP TVS or Ford Racing 2.9 Whipple for 2011

Rather than resurect an old thread i'll use a new one. If you are certain that 700 RWHP is all you will want and your only mod beyond the the supercharger kit will be widened wheels with wider stickier tires.....and maybe a new dual fan HE, which kit would you prefer and why?

Re: VMP TVS or Ford Racing 2.9 Whipple for 2011

In short go VMP. I had this diecision to make a while back. Ford wanted to have the blower installed then they would determine later what the tune would be and send it to the Dealer. The custom hands on Justin approach was the right diecision. I have 5K miles on my 2011 since the mod with perfect experience. You also must add the inner cooler with twin fans. Heat is the mind keller.

Re: VMP TVS or Ford Racing 2.9 Whipple for 2011

From a technical perceptive, either will do ya.

I liked the visual appeal of the polished Whipple under the hood.

Re: VMP TVS or Ford Racing 2.9 Whipple for 2011

Here's the thing.. the VMP TVS Supercharger uses the same 2.3L TVS unit from Eaton. This same unit is available from Ford Racing Parts Direct for a song. However I spoke with both Ford Racing Parts Direct and my local SVT authorized service center and both said that this Eaton 2.3L won't work on the 2011 GT500.

That said, I did read on the vmp website of someone installing this very same unit on a 2011. So I'm confused.

The other problem is that the TVS is only competitive with the Whipple because it involves a pulley swap to crank the pressure to 17PSI - which is the same as what the Whipple achieves with the stock pulley. In other words, the TVS is running harder and hotter to achieve the same boost as the Whipple.

On the Ford Racing Parts Direct is the 2.9L Whipple that is priced the same as the TVS unit. It is "authorized" to work with the 2011. It is a more sophisticated design, more efficient and runs cooler.

The choice is obvious in my opinion.

I went with the 2.9L Whipple and so far very happy with that choice. The 2.9L Whipple leaves you room for even more than 700 RWHP when the urge strikes you down the road to add a little more !!

Cobra Fred posted above that he went with VMP/TVS and to clear things up a bit, Fred's GT500 is in fact a 2011. You can't see that dyno sheet, but his car put 488hp on the ground bone stock, and 641hp with the VMP TVS (and Cobra Jet throttle body). Justin did the install and tune in just a couple of hours at the Shelby Fest back in April.

When I get around to increasing my hp, I'll most likely be looking to Justin & VMP. A very impressive young man!

Cruise On,

Yes, if the end target is 650Rwhp, the TVS is a sound decision. It makes better torque down low but does not have the big HP at high RPMs of the big twins. That is what sold me on the TVS as a selection, since I drive alot more at 2k RPMs to 5k, than above 5k. The TVS also seems to be a better overall 'fit'. No rubbing on the firewall, no silicon seal required..... If your target HP is above 650Rwhp, you will need to upgrade more items than just the blower, so I am keeping that in mind as well.

BTW, the bigger is always better remark I saw is a bit noobish. Even novices know you are better off having a blower 'correctly matched' to your HP target and driving style than having a giant blower planted.
