Jerry - You prove my point. I pulled similar numbers as you did with same conditions and issues with clutch. Fast forward to Better clutch, Jed’s headers, smaller Upper pulley and much more recommended by the same guy who did your tune and I gained a bit over 30whp. Hence my point about 600 wheel.
Just because one or two cars are able to hit those numbers, it does not mean every SC car has a potential of 600. Here is what i’d Say is the best way to get power out of e39 M5, find a way to keep that engine cool.
By the way, I have a better Intake and have not noticed performance gains.
If I wasn't clear, I am definitely in agreement with you about 600 rwhp. I don't know of any cars that have 600 rwhp that have not been sleeved with the exception of the one posted above(absent a race motor by Dusty perhaps--they delete VANOs and are pretty secretive about that info!
). I don't necessarily doubt the results, clearly cooling is a priority (both IC and meth). But I am not sure I want to live that close to the edge. Did I miss the AFR's? That would be pretty important here.
Frank was guessing my setup had 30-50 rwhp with better clutch, so your numbers put him in the correct range. I don't know that the headers or my bigger TB's do much for adding HP with FI. I do have the option of 88mm from 92mm for another 1-1.5 psi of boost. Right now about 8-8.5.
Maybe we can run some hoses from the AC to the plastic intake ala Dodge Demon for better cooling??? LOL
