1200WHP with VMP 2.65

Gen3R... gonna be awesome!
Not too happy a Gen3R is already releasing. You guys know damn good and well this R model could have been released at the initial launch. The lessons learned from the Gen2R would have made it easily possible. Good business move on VMP’s part I guess, but kind of shitty for the rest of us.
Anyone with a Gen 3 knows there’s a bunch of potential to improve the case. I’m guessing there’s more to it plus working with a different manufacturer than Roush. Damn I never even dynod the Gen3

I guess, but even the regular Gen 3 is 1200+ rw capable with a decent combo. See first post.
The VMP 173 is the largest/highest flowing DBW oval throttle body on the market that I'm aware of. It is a good bit larger than the KB 168.
The revised 173 version has been working well on Cody's car.
Well, a 10.7 built motor, with head porting, cams, on E85, and pullied to the max, should make lots of power. I would like to know the boost figures, but I guess my point is this is more of a max effort build vs a decent combo.
For every 1 of the VMP monos that are working I'm guessing there are 10 that aren't. Myself and several others received the "revised" version of the VMP 160 a couple weeks ago and none of them work, they all failsafe when hot. That's what Catmonkey means by "usable".
Yes.
As far as the 173 goes, I’m awaiting my conclusion until I vet it fully, both dyno and street. It might be bigger than the 168 from KB but it’s not that much bigger. I’d guess 10-20rwhp tops on a maxed combo.
I currently have a 168 running perfectly on my 2650 and I’ll test it against the 173 on the dyno.
Same goes for the JLT 155 vs the DD149.
Testing is fun

And yet they are still on gen 1.0 throttle body.
If only they had put the effort into the TB that they put into improving the gen 3 (which only a handful have and even fewer are actually working well...).
J, have you installed the 173 yet? If so, any seat time?Yes.

No sir, waiting for the dyno day most likely. For now just cruising with the 168 which is fine. Technically the clutch is still in break in anyway and I’m not going WOT until dyno either.
Hoping to coordinate work and dyno within the next few weeks.
I’d prefer my tuner to evaluate it with me but I’m still hopeful. I’d prefer no adapter and straight 173 with the max boost 2.4/15% and 1100rwhp they’re expecting (Starkey and Lidio).

Nowhere near a max effort build, 25-26 psi through the pull
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.

Closer to max effort than not man, let’s be somewhat realistic.
Please enlighten us on a max effort 5.4 TVS2650 Street/strip build.
You guys have a great combo but it’s pretty maxed.
-J
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.
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.
