580 to the wheels ? damn! what year is that ? Also , won't be to my use but the Techy guys here would love to see an actual dyno chart which they can decrypt and then comment accordingly lol

GT-ER

I'm guessing it's modded.

HeissRod

I'm seriously gonna sell my wife's GC SRT8 for one of these!

RedBullJnky

I see Renntech's X5M all the time at the track. And I want one.

Numbers seem fishy to me. My truck is putting down 455/555 to the wheel with a tune. Is this truck downpiped? If not I call bull****. Anything back from the downpipes hasn't been known to pick up any additional power.

We need to know mods on the car but I don't think it is that farfetched. The new M5 tuned was recently advertised at 700 crank hp and the X has the same engine.

dyno must be broken lol

PACougar

That's a hell of a correction factor.

SLOWCAR930

what am I missing never had car dynod before?

SLOWCAR930

had dinan software before, seems faster now. Went up against factory x6m. Won by about 4 cars to 100kh. It takes m3 easy, Dam is his dyno rigged should I check console for bottle of snake oil?

Numbers seem close to others on internet that have posted numbers

So the new V8TT for M series stock 467 at wheel and 580 after tune ?
This is super impressive

SLOWCAR930

I've got a 2004 e55, ec tune, he, pump,kn,wave trac posi, (anti slip belt not installed yet. trans software, 822 t body, fuel rail. and I cant beat x5m. Especially off the line I time suc with I phone got 3.7..e with nitto 295 gets smoked. I need a new car 997 turbo s pdk before fall I hope...or awd e63 amg wagon

PACougar

So based on your list for your 55 you don't have a pulley or headers, it's no surprise you get smoked.

Manuyc

That's a lot of power from a tune

SLOWCAR930

sorry yes ec sc pulley...headers in 3 weeks maybe then on a roll I can get it..have you raced x5m from a dig yet?

SLOWCAR930

forgot ttm scoops

PACougar

I haven't, but considering I run MT drag radials as street tires I wouldn't be too worried

forcefed4door

looks like with just a tune the x5m run 12flat. so I assume it can definitely be quicker than e55 quite easily unfortunately :-(

PACougar

Well, certainly a stock e55.

CharlyE500

Stock E55 should also run in 12s, the X5M is AWD will have advantage from dig.

GT-ER

I tried finding an X5M or X6M with mods and they all dyno'd UNDER 500whp. The correction factor on the dyno posted is crazy high, which may explain it. Also, if the dyno was a hub dyno and not a chassis dyno then they read higher as well.
