1200WHP with VMP 2.65

Handlebar Moustache said:

No need to split hairs. The point they are making is that the motor in that car is more built than 99.5% of the GT500s out there. 1200 whp and 26 psi is not what people without significant internal engine work and a lot of supporting mods should expect from a gen 3. Obviously “max effort” is a relative term. Any build can be pushed further with a bigger budget, so theoretically (unless you are bill gates), there isn’t a ceiling for what can be done. That said, nice build, OP.

It’s not splitting hairs, there’s just a difference between a fairly basic,
matched rod/piston/H/C combo and a true max effort combo.

There will eventually be a ceiling imposed by the engine’s architecture.
The point I am making is that Cody’s combo is not a max effort combo even within the context of the 5.4/5.8 GT500 engine platform. To me, max effort means max effort, not simply built
or modified.

“Max effort” often gets thrown around to imply there is nothing more to be had. That isn’t the case here.

Nothing about the combo is max effort. The heads aren’t max effort, just Ron Robart’s standard GT port with stock valves - 350/300. Not his large port/+2mm 390/350 heads.

Stock cube, stock crank, iron block, 10:7:1.

The combo is pretty basic, just pretty well matched at this point.

What does a max like effort combo look like?

Sleeved 5.8 block - O-ringed and dry decked, ~400 cfm heads, billet crank that allows 8000+ rpm operation, more cam (than Cody has) to match that RPM, cut and ported supercharger, 13:1 CR or better on methanol. That’s closer to what max effort looks like.

Yup and custom kooks headers, bigger exhaust etc... The list goes on. My build is a middle of the road build that works. Problem is 90% of GT500 owners do basic 9.x:1 builds with parts that don't match. Alphabet cams ftl...

90% of gt500 owners never even tear into the internals of the motor. They bolt on a couple hundred RWH and stop there. You’re in the 1% WRT modded GT500s. I think that was the basic point that was being made. ‍

So what you are saying is a blower swap alone could be considered max effort to some since most 07-12 GT500s are still on the stock M122. Lmao

60-160 lets go

J and Scott have the answer via KB 168 adapted to the Gen 3. It’s proven and is HUGE. No reason to go bigger IMO.

VMP 173 on the top, KB 168 on the bottom. The 173 definitely leaned out Cody’s tune, so there was some air flow improvement with it. Still unsure of any direct gains because the 168 went into failsafe @ ~6000 rpm every pull.

A back to back comparison on a 1000+ rwhp combo would be interesting.

I’m just saying that the way people use the term “max effort build” is obviously relative. Pretty simple concept.

When a 2650 makes 1300 mine will then be considered medium effort. I get it.

What happens if a "medium effort" combo makes close to 1300 with Gen3R and gear change?

Nothing. VMP gets more of your money than if they’d have just made a single release.

Nice combo and great results OP, and it’s good to see that the Gen3 TVS can keep up in terms of airflow at your power level.

Here are some things to consider that back up Handlebar Moustache’s position. Here is a VMP video of actual results on a stock street driven 2012 GT500… less than impressive for all the hype surrounding Gen3. And what about the dyno results VMP keeps promising with Justin’s personal 2012 GT500 after adding long tube headers? Months of “good air” have come and gone… my guess is that the results aren’t good enough to sell blowers. Their first screw up was to design a new 2650 blower case around a new, unproven mono-blade throttle body design. Adapting a smaller throttle body to the larger intake opening just because that is all they can get to work is ridiculous. Kudos to the guys adapting the KB 168 mono to fit and getting great results, but VMP should be embarrassed.

I do agree with that...

You are also a max effort build... why act otherwise?

LMAO. Ok sport.

You also have "minimal" weight reduction, right?

Medium weight reduction.

It's your story.. tell it how you see fit.
