Nice on the retune and pulley upgrade. Is the 2.3L Whipple a version of the TVS that multi manufacturers use or is it a smaller version of the 2.9L- Just curious, and if it is a TVS variant, what made you choose the Whipple model over a Vmp, or a Rousch cased variant.
Thanks!
The Whipple is a twin-screw design, as they call it.
The TVS blower uses 4-lobes on the rotors, and it's a huge improvement over the older Eaton blowers which were 3 lobes.
The Whipple or the TVS are both great designs, they both can provide plenty of power and even at my new power level I have plenty left if I wanted to push this blower more.
But with a stock bottom-end, I'm done for now.
As far as why I went with the Whipple over others, I wanted the same kit that Ford uses, and that meant the Ford Racing kit which is basically a Roush kit with the Whipple on top instead of the Roush blower.
Lower manifold, heat exchanger, they're all the same as on a Roush kit.
My fiancee has a '13-'14 GT500 TVS on her Shelby, and that blower is awesome. Stock pulley on there (the elbow is supposedly ported a bit) and it put her from 551 rwhp with the factory blower to 643 rwhp with the TVS.
And we can still go to a smaller pulley and get more out of it.
