61.64, the Seb turbo's? I am not sure. they are custom ones he spec'd out. Compressor is the same as mine. He changed the trim on the turbine side. Looks like he has the larger turbine wheel. The compressor starts running out of the efficiency range at 25psi of boost. IAT's start to climb.

My turbine wheel ran out at 29psi of boost at 10:1. 28psi was 996whp and 29psi was only 1004whp. The turbine became a restriction.

That is the crazy part about all this. Learning what does what can only be done by testing.

Wouldn't Tial have an idea what turbo's would be best for your application?

Not a bunch of data on a VQ37VHR twin turbo. The data I have shows me where I need to go. Where those turbos will run out I do not know until we test it.

FWIW, Tial technical support is top notch. They were working intently with me on my bov flutter issue. Couldn't ask for a better company to work with.

My choices are limited with the Fast Intention cast manifolds. The right thing to do would be to have a set of custom tubular exhaust manifolds made and put in a pair of G35-900. Unfortunately, money will limit what I do. I do not have an unlimited budget.

At your power level you almost need an unlimited budget :tup:

Cause I keep going in circles until I think about it enough. I just looked at a Carbon Z post on Instagram. Looks like the response is good. Like I have said, I am very picky when it comes to turbos.
The Video that he posted a month ago where he's doing part throttle and hits 16 psi of boost ?

AMS uses these on there Alpha 15 kits with huge 4inch intakes and 3.5 inch down pipes. Doing something like that in Z for sure would be all custom would be a bad*** setup though

Well, I have driven it twice since the last O2 code. No issues. As long as I get the cylinder temps up, all is well. It does have something to do with the fuel I am running since I do not run pump E85. Vince warned me of it when he tuned the car. He said to look out for a little stumble until I get the cylinder temps up. The only time I get an O2 code is when i putt around.

Down to my last barrel of E90. About time to order some more. LOL Thank goodness I don't have to put my car away like you folks do up north. I would be miserable. Nick's startup map works like a champ. Starts first try.

Carbon z posted his car for sale with his turbo specs listed
