I know that's why I'm using RB engines.
The thing is, I have been using JP engines solely for five years, with no problems whatsoever.
For 2009 I bought two P3L tuned engines and one Tuned Eagle, ceramic bearing and pre-run in the factory.
But when I put the engines on the track the two P3L's were much faster as the eagle( 103km/h compared to 97km/h) .
The Eagle was slow on bottom end and in topend.
So I contacted JP why my 400 euro engine was being completely trashed by my 200 euro engines.
I was pretty sure the engine was out of tolerance and simply wanted a new one. As a very loyal customer I think I should get that kind of service on a 'handpicked' engine. Off course I didn't get a new engine and sold the Eagle paperweight.
Bought two RB R3RC's and never looked back.
The RB's are doing 108km/h on the straight btw.
