Guess the Dyno Numbers

So I never got a baseline run when it was stock so I don't know where it started.

I'm running a 2013 M6 ZL1 on 91 octane. The only things it has installed at the moment are RotoFab intake, 2.4 upper and some muffler-less exhaust with stock cats and a tune. I had some crap Smith's gas in it when it was getting dyno'ed last summer and they said they couldn't do something with timing because of it and it ran 550RWHP and 556TQ.

Anyway, in two weeks I'm going in for another dyno as I'm getting the BTR Stage 3 cam & kit as well as id1050x injectors installed.

Anybody want to take a stab at what it'll make this time around? It's supposed to go in on the 21st to get the dyno done.

-I'll definitely update this thread as soon as humanly possible when I get the car back that day.

A 2.4 (26%) upper pulley and stock injectors is a Death wish for your engine it was running out of fuel.

And it wasn't the crap gas it was way too much boost for your injectors and any pump gas.

Our cars make 575 RWHP with 10% overdrive crank pulley and stock upper on stock injectors with a Rotofab and JRE tuning.

If you have Long tube headers, ID1050X Rotofab and a good tune you should make 650 RWHP on 91.

You will need a fuel pump voltage booster also so keep an eye on that fuel pressure.

Ted.

Any pulley with stock injectors/fuel pressure is heading into dangerous territory...

Glad I'm not the only one with this opinion.

My buddies ZL1 was at 93% duty with just headers and roto-fab. Even that's getting close to the edge, I would want at least 5-10% of overhead in a fuel system. I would imagine with that much overdrive the OP's injectors are probably static at full load.

So I'm actually quite disappointed with the numbers... Only reached 587hp and 570 torque.

+37hp and +14tq

Something is very wrong and a cam with no headers is like a runner with boots.

Here is the dyno they sent me home with... I could go surfing on waves like that. What looks to be wrong here?
