Which one should I buy? Both make roughly the same power, both have pulley upgrades, Whipple looks a bit simpler to install but costs a grand more. Let the debate begin.

 

Hmmm...I'm assuming you mean the Roush TVS? I voted Whipple but then again I'm biased.

 

Roush

Whipple is awesome. I give it it's due respect. But when you compare $$$ vs. gains, the Roush is a better choice IMO.

 

I'm going to have to say whipple!

 

I'd take the whipple out of those two. But for TVS I'd choose an edelbrock because of the complete kit.

The Roush TVS doesn't include spark plugs, a fuel pump upgrade or a tune, all of which edelbrock and whipple provide.

 

whipple. you will be very sastisfied. when i was getting ready to get a FI setup i was looking at roush as well but i think whipple has more potential if you decide to build your motor and turn up the boost. MY 2 CENTS.

 

Steeda's race belt system is made for the whipple...
and the roush TVS is not CARB legal in CA, but you wouldn't care about that.
