Hits like a jack

As soon as your car starts you can hear it has a Thumper series cam. The other cams run smoothly until the car has been driven for about 2 minutes. With this fist he cuts off a jump like a lumberjack.

Pros
  • Part number 26113-24 Valve springs available but not required
Cons
  • Not bad
