RHO on the Dyno

[cconnorhtx]

Well these guys got a new RHO and disconnected the front driveshafts, then hit the dyno.

Numbers look very good for stock (460whp / 466 tq)

How much are we losing by having the front driveshaft hooked up though?

E.T./acceleration wise I'd say zero, I'd bet the rho would be a rear tire killer in 2wd!

Only about 120 horsepower less and 90 torque to the wheels compared to my stock Trx made, nothing a quick tune wouldn’t make up for lol can’t wait to mod the rho!

A hundred(ish) pounds off the nose with the RHO will also be helpful with weight distribution at launch. Just a JB4 will definitely put it up there with a stock TRX

I find it amusing how so many people are hung up with acceleration on a truck basically designed for off roading.

More power doesn’t hurt in the dunes lol

What’s the difference between red and blue lines?

In the rho graph it’s just 2 different runs,

Edited - was looking at the 6.2L graph.

BMW is notorious for underrating actual power/hp levels their engines are making. Specifically/Currently the B/S58 inline six cylinder turbo motors in particular.

Why they choose do to this I do not know...but love it! Loving my wife's base B58 X5, and about to put a JB4 on it.

It's generally accepted that whatever power level BMW says is the WHEEL horsepower being made, not crank. Maybe Ram is doing the same with the RHO?

Ok the B58's have made their rated crank horsepower at the wheels.... But they're also not exceeding it by 100whp. I was looking at the graph posted above and not reading - that's his TRX, not his RHO. So nevermind my jibberish.
