They did ten (10) runs. Hitting the rev. limiter in second takes less time than in third.

Dyno time = money.

It was dyno'd in second for "safety", not to save time. Some dyno operators don't like spinning the drums that fast.

That's good to know. I learn something new every day.

So why didn't they correct it then?

Maybe the shop was trying to wow their customer with awesome numbers, or more than likely they were just ignorant on the platform.

Here's the VLOM tray from nmp0098's build (stock at the bottom):



From nmp0098:

9) The two VLOMs side by side. The official stock replacement part is thinner than what came on the car, and after I ordered it I checked and it is the same part number as the G8s and DOD trucks. Bolted in with no issues (107 in-lbs).
So, with the G8 tray being thinner, will the intake ribs still need to be ground down underneath?

That's unfortunate because it's the accurate numbers that we're all looking for.

I've trapped speeds with a good 4 mph range in one night...That's a BIG difference.

Delphi trays are thinner and Eatons are thicker.

Ground down some fins on the intake and cut/welded the OPSU tower.

I'm using an Eaton too. Had to grind down the fins and knock a few tabs off of the tray. I test fitted everything without gaskets though.

Ah so either way the intake will need to be modified due to the MAP sensor and whatever that other thing on the left is, lol:



Pics of your modified OPSU?

Yeah, the MAP can be moved to the front (EGR location) or drilled for mounting on the back. That monstrosity is filled in with a freeze plug.

What if the intake doesn't have the EGR hole up front?

EDIT: Lol I hate to derail this guy's thread.

Drill a hole in the back of the intake and Silicone it in there.

cut the rear vacuum nipple off with a hacksaw and use a screw driver to pry the tabs which hold the dam thining in, out. Then clean the hole out and scuff the surface. Use some epoxy and install a 1 31/32 freeze plug into the hole. The map sensor will install in the rear. Just drill a. 441" hole on the flat side of the rear manafoild. Mount the map with a small screw sealed with PST gel. You can get a map extension harness from verious companies online.
The best bet is to mount it up front on Brian's adapter. Doesn't really matter though, since both locations will work.

Can we get a sticky for the LS6 swap info?
I've been on this forum for almost a year and see this come up occasionally, and quite honestly, though I've read this stuff I'll have to look at it again when I actually go to do it.

Back on track! lol.
