Did the turbo Y plenum come coated or did ADM have that done?

I believe that is an Andy thing. He gets the DPs/etc setup so he can weld the WG back in then sends everything out to be coated. The standard AGP kit comes with ceramic coated adapters, turbine housings and downpipes. If someone wanted the outlet adapter coated I'm sure Ben/Kevin would do that for a minimal up charge.

I have a kit here. I'll have to double check,I don't think it's coated.

Yeah. I think that's an ADM special. Looks good that way.

Very cool build, just wondering why you would use an LS9 cam instead of a custom grind though? From what I have read cams designed specifically for turbo cars will always perform better than cams for supercharged cars if you're running a turbo set up. I believe it's because for an extremely small amount of time both the intake and exhaust valves are open in an NA or SC cam as to use the vacuum to suck more air into the cylinder, but this isn't necessary for turbos cars and it results in less power. -- Rant over, why not use a custom grind? Car looks super good by the way!

Ls9 cams are cheap, drive like stock, and with this turbo kit have made 1000+rwhp so why put a big lumpy cam? Let the turbos do the work. I would have kept a stock cam for anything under 800rwhp.

Exactly.

There was a cam we used to put in every twin turbo corvette we ever built(My Lingenfelter days 2002-2006) called a GT7 that was developed when John Lingenfelter was still alive.

It has a shocking resemblance to the LS9......John was very close with Gm

FROM LPE WEBSITE:
Before the LS9 was introduced LPE used the GT7 camshaft that John Lingenfelter designed in 2001 to be the perfect camshaft for boosted LSx applications. The GT7 was 208/230 @.050 valve lift and .554/.546 and 121 center line this camshaft produced excellent power and still had great street driveablity. In 2009 GM introduced the LS9 in the C6 ZR1 supercharged Corvette engine. After comparing specifications on the camshaft and finding out how economical this is due to it being mass produced Lingenfelter discontinued the GT7 and started using the LS9 in supercharged or turbocharged applications.

While that's all true, what's 300 bucks when you spend X thousand on a TT kit? More to what unreal said, a custom cam doesn't have to be lumpy. You can easily get a cam grinded out extremely similar to an LS9 one but optimized for turbos instead of an SC, but still a wicked build!

I would do custom too because I would want a bit bigger, but the ls9 cam does work great. Plus you don't need crazy dual springs/etc so that is some money saving too.

Hell, I would have kept the stock cam in this build. May have taken another 1psi to hit the numbers but boost is easy to turn up.

Stay tuned. In a week, I will be adding a boost controller to the base AGP kit with the stock LS3 cam and wastegate recircs. We'll just see what boost it will take to get comparable rwhp.

Probably 1psi more than without the cam is my guess. Why stop there though, keep turning it up until you run out of fuel system.

I won't run out of fuel before I run out of engine (unforged). I have ID-1000's and LPE twin fuel pump. I have to stay realistic with boost with respect to stock engine capability to handle boost. I'm hoping for a safe 9-10# boost. I'd estimate 650-675rwhp outcome at this altitude (mile high) with that boost.

I would keep turning it up until you hit 700rwhp uncorrected. Keep timing in line and AFR good and it should live a long long time there. 700rwhp on a turbo is ~650rwhp on a blower because you aren't turning a head unit taking 50hp away. You can definitely push turbos farther on stock motors.
