That's how you gotta roll in cars that weigh this much LOL
Yep! 550-650rwhp boosted??: Ain't nobody got time fo dat!!!!!!:kaboom:
700!!:rockon:

This Coyote motor isn't any diff then any other combustion engine.
U need good octane when running boost. Its so important its crazy. Half the guys on this site don't realize it.
I have going a long time with my VMP tune and TVS almost 2 years now.
Anything over 10psi with pump gas your looking for problems I don't car what anyone says.
12-13 your nuts making top gear pulls without Torco.
Only takes one time for bad gas at the pump.

so what has VMP said about this whole situation
(sorry if i missed it)
Pretty sure Justin is in MD this weekend at the NMRA thing, at least thats what it says up top there in the VMP section.
FWIW I have VMPs latest tune and I use it for a base tune and tweak it myself with PRP, the 82mm tune is pretty mild and doesnt have as much timing and is nowhere as lean as the log posted with 8-9psi so who knows.
I am not blaming the tuner, but there is good information here. I based my purchased and pulley size off what was considered safe by VMP prior to purchase on pump gas. Should this advice be adjusted in the future, or more information be put out there? I think so. That's the importance of this thread.
My datalogs before this second tune were analyzed by Justin and he said A/F looked perfect, but my air charge was high. I pulled the bumper and found a small kink in the intercooler inlet hose right at the inlet. This wasn't a huge issue, but it was resolved. I flashed this second tune and went on my way not thinking that anything else would be adjusted. The only changes mentioned were adjustments for revs/mile for my tire size.
I honestly didn't think this setup would make as much power as it has shown in the other thread. 650/600 with a 75mm pulley is more than I would want. I wanted to be at 600, not much more. Comparing the regular Roush setups a 79mm would put me pretty close to that.
I haven't heard back from Justin, but as said he's been out of town. I will e-mail him today.

Everything you did makes sense, I would have went about it the same way if I went with VMP's kit. Even 600 is a lot of power on a stock short block though.
Its really hard to compare dyno numbers from different dynos, someone at altitude can make a lot of corrected power on a lesser fuel system that will kill an engine at sea level. Always best to look at uncorrected numbers from boosted cars. Not to mention different brands of dynos vary quite a bit, the most popular dynos in the neighborhood are the ones that read high and not low
If your intercooler wasnt working right there is a good chance you already damaged something testing (not making excuses for VMP, been there myself). No doubt that log you posted shows some pretty aggressive tuning, there is a good amount of timing and the a/f was pretty lean up high, it was dead by the time it hit 4th gear IMO I'm assuming no cats (or at least COT was turned off in the tune) since COT should have kicked in, or it was just out of pump/injector. The reason I mention cats is if one side melts and blocks one bank the exhaust it will have a ton of crankcase pressure and smoke like a pig. Quick compression test will tell the story. If you had no cats then never mind.
Having broken a few pistons on various stock engines in newer cars over the years pushing it a bit too much I feel your pain.
It was working, but it was definitely higher than it should be. It was also 93 outside when I did the datalogging. The last log showed 117 air charge which is pretty good after driving a PD 7 minutes lol. However it was night and we had some cooler air for this time of year.
I have a ORX. No cats.
In any regards, this setup makes some power. I don't care about dyno numbers, but those were SAE posted in that other thread. My dyno is to look at trap speed. I just didn't get that far lol. Again, what happened, happened. Time to build it, and see what it does.
I will post pictures of the tear down when the time comes. Won't happen overnight, but it will happen soon enough.
Justin has said it so many times that an 82mm and closed air box is what he recommands for an everyday street car. Anything more like an open element filter or 79mm pulley needs Torco or a splash of race gas.
There have been so many threads on this if u want to play you could possible have to pay.
I know with my setup its just a matter of time.

Not what he told me via e-mail before purchasing. He said the 79mm would be fine for daily duty, and a 72mm with Torco would be good for the track.
Again, the point is moot. If there are a lot of threads with him saying something different, then I am not sure why he would tell me different directly.
Sorry to hear about this, J.
I was really looking forward to your results.
