Went to the dyno today

CT335xi · 03-31-2018, 03:37 PM

Well baselined my stock 50i today on a mustang dyno, I was pretty impressed, car has 42k miles and probably on original plugs. I should of told the dyno operator to take it to 6000-6500 rpm , but he only took it to mid 5k, though they don’t typically make much power after that as power and torque start falling off.
Anyways it put down 368/417 on a 4th gear pull and 366/428 on a 5th gear pull.
I’m having trouble posting photos of dyno graphs/ resizing photo, but if somebody wants to help me out to post them, pm your email and I’ll send the photos. I wanted to get this done before I put some sort of tune on it so I can see the improvement, also was going to throw fresh set of plugs along with x5m air filters too.

Nice numbers, that's some impressive tq.

Do you know if those are adjusted numbers?

I believe there uncorrected , though he did have the info for a 50i in the data base for programming for the dyno , he says he has to enter the weight and such for loading. I actually went today with my buddy to pick up my evo 8 that he was adjusting the tune on, so I asked if I could get the x5 on there to see what it puts down and he was like yeah definitely. That was the first 50i he has dynoed , I thought it would do like 350/400 since it’s a mustang dyno. Just to compare my evo8 has a built motor 2.3 stroker, big cams, full bolt-ons, running a turbo somewhere between a 30-35 r on 93 pump/ meth @ 30 psi it put down 468/402. The 50i is laying down some torque!! My evo stock on his dyno does 205/210 to the wheels and it’s rated at 276 flywheel hp.

Bmw is always conservative and claims 445bhp on the X6 X50i, which would be around 380whp, so wouldn't this be really low? What am I missing?

Not really it’s right on for a mustang dyno , I have seen 350 to the wheels also.
If this was a dyno jet yeah I would say 380-400 whp , but all dyno’s read different, not to mention dyno operators can have them calibrated to read higher or lower.

Nice numbers on a mustang. I am impressed. Now do the bootmod3 flash and
Let us know what we are looking at

. If it goes to 450s on a mustang I'd be thrilled.

Haha I’m still undecided which route I will go , but will post new dyno results once I do the tune.

I think if you rev beyond 6000rpm next time, you may get better hp results...

Not much or maybe none look at the graphs the hp starts dropping off after 5500 ,but maybe with a tune it may make it a little higher.
