that AWD brick on 35s will suck a lot more power through the drivetrain & parasitic losses than i think you're thinking.

How high are you spinning it? With those valve train upgrades you need to go up in rpm, I spin mine to a little over 7k. There is a ton of power to be had over 6k and you just added the insurance to spin it up there.

I never loose track of the fact that's its a 6500lb sheet of plywood going down the road.

I don't spin it high at all so I know there's more there. I'm happy with how it runs regardless of the number. As soon as I get tired of it, I'll put a blower on top of it. It's a fun toy and probably not another one like it anywhere near me.



Thanks for the input.

Tim

I think I'd be tickled to death to see 390, anytime I hint at hoping mine makes 400whp everybody laughs. By everybody I mean @arthursc2

Time, well a lack of it during business hours. Plus I still haven't really messed with timing it's at 22* on the top end now.

It can be but most likely is not on a modified application. On a stock engine/tune, I would feel better about the numbers as a lot of time has been taken by the manufacturer to dial in the parameters used to make the calculation. As the engine and tune are modified, these parameters are also changed. Depending on the tuning method, the parameters may be changed in a way that does not correctly calculate the way the stock tune did.

If it runs good and you are happy with that, don't get caught up in the numbers. That can be a very slippery slope trying to make a number.

I'm looking for a 4 wheel dyno but haven't had much luck. I think the closet to me is in Tampa.
