What's the highest E46 M3 dyno at altitude?

Really need to know if there is anything higher than Radz car? We finally got round to tuning it for altitude. At the last dyno day we just ran it with the map tuned for sea-level. We ended up with 287.3hp on the wheels, which is just on 215wkw:

On that ambient correction you will get the same uncorrected power at the coast!!!
25% ambient correction is far from Reef altitude power!!!
but still very good figures!!!

I saw LOCO's E46 M3 make 201kw on a uncorected dyno 1500m above sea level!!!

Out in the real-world, the car used to make 338hp on an uncorrected Dastek loading dyno at sea-level.

Loco is also an Xcede car tuned my me. Radz car flows a lot more air and makes a lot more power. So according to my logs of both those cars I have on my laptop, Radz will make about 15-18 more kw than Loco on the same dyno. Maybe we should have sent him to RGM for the dyno day. But in any event there were lots of cars from RGM that ran at the dyno day at KAR and they all made similar power. What you rate?

ambient correction factor doesnt take power away it ads power. Its a SAE J1349 formula to work out the cars power to spec back to coastal readings!!!

No if its stronger than LOCO's its wild!! and i take my hat off..
I was just questioning because you claimed Altitude power but its measured with ambient corection!!!

It's altitude power. All the hyper-powers add ambient correction. You can't compare different types of dyno. At sea-level he used to make 338hp with no correction. Take away 17% and it's around 280hp.

I agree that you cant compare different dynos.. so only one way to settle this!!! 1/4mile drag race! how about ODI on the end of the month????

I don't know if there's anything to "settle", but yeah I'll ask Radz if he's game for ODI.
