So question I've been looking at the twin bore sprintex super charger but on the options it gives me with front cover or with out andthe price difference is huge but what does it mean like why would i want it with out a front cover

 

I was the 1st person to ever test a sprintex on a Mini Cooper, it failed our testing
The TVS900 is a much better and more reliable unit. 3yr warranty on them too. We have replaced many sprintex's already with the units

 

The difference is that the center sections are used for many different kits, and can be purchased separately for custom or rebuild application's. Where as the front and rear sections make the units vehicle and kit specific.

 

I have the second generation Sprintex and it's great.

The kit Revolution tested years ago has been discontinued.

The Harrop Eaton TVS kit is a nice piece also.
