Nice , congratulations ! Man at 4500 rpm, it must pull really hard
It would be cool to run it on a DJ just too see if you hit your target, but there are so many variables between dynos ( day, humitidy, make ). Besides not all DJ will read the same power neither will all MD. I dynoed 433 whp on a AWD MD back in May, the guy said that according to all the cars he had done, I would have dynoed 507 on a DJ.
