"........., but after almost 5 years of ownership, and hundreds of mods on my MINI, this was the best change ever. No questions asked, and as I said in other forums, if given the chance, I'd definitely do it again with a Thumper HEAD! "

"....Good Lord this thing breathes now! Eyeball flattening, neck snapping, head prints in the headrest torque.

"....Wow. I'm not easily impressed. I'm a long time bike guy and I've had motorcycle heads done by everybody from drunken chimps to serious big time professionals and I've never had a more impressive change from head work than this Thumper head. Big time torque! My butt dyno notices no loss at real low rpms and from about 3K up my car just tucks it ears back and hauls. Big, big improvement."

How about you MC guys....

"...As I said earlier, the car feels much lighter (but it's just more power) and it picks up speed like nothing else. This experience is based on a 4-year-old MINI with STOCK ECU, as all my other mods would finally start to work together in harmony.
The new top speed is 130mph, but again, with a different ECU it might go higher. The thing that amazed me the most was the acceleration. The car just picks up and wants to go. Next thing I know it's 5K RPMs and I have to be alert to shift. And then it's the same thing again. The power doesn't die until I get to 6K RPMs in 5th, when it's going 130mph... "
