My god,
I thought that this might calm things down but it looks like its stirred things up & I can only apologies as I didn’t mean it to, I only put my money were my mouth is trying to help as I always do.
On Boxxers Engine you are all talking about 4% between rollers, I done this to prove to my self that in the car My customer would see the numbers that I showed them on the dyno sheet that I give them
Everybody is think about Numbers ,Numbers ,Numbers, Numbers
Please remember
The most important thing is how it drives & if you think that it runs as good as is should No misfires ,no det ,ect & if you got value for money on the Engine that you purchased.
Like I have said already choose a rolling road that you are happy with & stick to it IT’S YOUR BENCH MARK FOR FURTHER CHANGES.
If you can’t find a rolling road that you are happy with out of all of them in London then take your Engine out of the car & put it on a Real Dyno like HT’s or Roushes
