Whipple vs. Roush

[may28th]

Mtf you dd right. WHIPPLE

Well the next time my power steering pump whines, I will just tell everyone it is my supercharger.. Lol

I am Leaving Cabo tomorrow to drive up to Hennessey Performance in CA. They will be removing the Procharger, and installing the Roush Tuner Kit. They are getting just over 600 hp at the crank, or right around 500 RWHP. I am super excited to get this done, and will let everyone know how I like it. It will be a few weeks, because while it is up there, I am doing a bunch of other work to the truck..

I love road trips....

600 is better than 525, I'm sure you'll like it.

 

[Whipple Charged]

I am going to first say that I am not qualified to make any argument here, but I read this, and thought it was interesting.

The new ROUSH F-150 superchargers are a positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with NEWLY redesigned air inlet and outlet ports, greatly enhance thermal efficiency, deliver higher volumetric capacity, enable higher operating speeds, creates a smoother, more efficient flow of air into the engine and has improved noise and vibration characteristics.

This was regarding the Roush kit.

Here is another one I found helpful in choosing:


The Whipple trumps the TVS in displacement; down low the TVS *may" have a torque edge on the street (stop-light to stop-light) but a twin-screw like the Whipple is superior above 15 PSI. Above 15 PSI the TVS starts to make more heat than the Whipple, so if you are going to go forged and throw 20+ PSI at the engine, hands down, the Whipple.

If you are just bolting it on a stock Coyote motor and you don't plan on going crazy with the power long-term, I would probably go with the TVS.

Lastly, the TVS is fairly quiet, and the Whipple has a screaming whine...so that is something to consider as well. Some guys want a loud WHEEEEEEEEEEEEEEEE and some want "stealth" with exhaust noise their dominant signature.

FYI, back to back test in a controlled envoirnment, the TVS2300 vs Whipple W140ax at 14,000rpm, 8psi, the TVS is 3% down in flow, yet has 16deg F hotter air and nearly identical consumption. When spun at same rpm, power consumption is 6hp more for the TVS and temp is 22deg F hotter.

When comparing to the W175axff, then its a more significant difference due to the lower SC rpm. To equal airflows, the temps are 31deg F different 18hp. This is at 8psi, at 15psi, the temp difference is well over 60deg F.

Hey MTF I spotted your truck today by the Whitestone bridge. I drove by in my Blue Supercrew today had to pickup some stuff in Queens

 

[MTF]

Was that you driving down the the Queens side I was standing on the crane and everybody said you drove by,
I got all these guys looking for Raptors. LOL

I actually meet the other Blue Raptor 2011 SC with graphics that has been passing by for a month I opened up my hood for him,
he'll probably chime in later sometime.
He wants to go for a ride, but we both did not have time, he took plently of pics.

 

[Mac]

Yes probably me around 9:20 am

 

[MTF]

Yup, I'll PM you my number if you want.

Big News!!!

Whipple is now supporting Long Tube Headers for non emission states

The tune is done, works great, all the safety settings are still intact, closed loop is still on,
a new model was built for the predictive system based on the SW LT's and updates and other changes.

Whipple will update any current Complete Whipple kit (free within 1 year of purchase of kit) that has any issues.
Anyone who purchases new, must state that they have LT, anybody that purchased for stock, and later added LT's, needs to pay for an update.
