Lol yes I did. What a joke that was. Iirc it barely broke 100mph.
I'm sure this build mentioned above is quite a bit more advanced. Seeing as how it's twin turbo. I'm sure it makes good power. However, without some kind of actual performance data I don't believe anything.
At over 800 rwhp and given the weight he should trap around 140. I don't believe it would though. I seriously doubt it would trap over 125.

What's going on in the 1st pic of the 'Underhood shots-almost complete'?
Really not trying to sink the slipper, but that's not a very attractive looking engine bay. Not doubting the workmanship.

The LS D585 coils used on that engine is more powerful than basically all COP's.
I have to agree with Pauly here, I think the fabrication and the details looks very good. Just a little powder coating and it would be pretty too ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
IMHO the stated 8xx rwhp is very believeable, if not on the low side..
32v 5l twin turbo on E85 @ 21 psi. That's insane.

twin gtx3076R's and then you're talking big power!!

The closest to this I can think of would be our BMW S62 turbo project, which is decently fast already running only 7psi on E85, but yes, at 21 psi I imagine the thrust on this 928 to be more than uncomfortable.
I can't see how this is going to keep any traction on 16" wheels, unless massively "massaging" boost build up until reaching peak torque.

So with that all in check, it will be a PHYSICAL limit to the bottom end, not a detonation limit.

As I am sure you know, since you have dealt with e85 - there is nearly zero chance of detonation under normal operating timing schemes. Obviously it reacts badly to hot spots, but those will be from the spark plugs, which are very different than what we use normally, and maybe the edge of the valves - especially the exhaust valves. We have valves in the 5L that are pretty thick at the bottom margin, so they should not be glowing.
So with that all in check, it will be a PHYSICAL limit to the bottom end, not a detonation limit.

If you don't mind me asking, what plugs are you using with the LS coils?

I am always sceptical. I've seen too many claims of big power turn out to not put down any mph. I'm not sure of your plans with the car but I'd love to see how much mph you can get.
It sounds like an awesome ride.
I have to ask though, why 21 psi on a 4v. Hell I only run 20ish psi on a home done 8v head and have made over 500 rwhp (determined by trap speed)
