What power will twin TC76 turbos realistically support? 408, TFS 245s, sheetmetal intake. 3" downpipes..

Although I have no personal experience with a setup like you've mentioned, my guest would be at least 800 rwhp.

TC76 Twins<- The particular kit I'm talking about has produced 920hp/860tq at a hair under 13psi.

It's hard to manage/contain all of the heat that setup makes...

I don't know about that kit but TTIX has made 940rwh @ 16psi with 62mm Turbonetics. I have a TTIX kit on my 418 and it made 708 rwh on low timing on 9psi.

I know a guy that made 1031rwhp with his PTK kit, but I don't think his turbos were that large.

The same can be said for every other turbo kit for the C5 except for the STS but that thing isn't getting near my car.

It's do-able.

I have a custom dewitt's radiator and twin spal fans. The bumper cover tag area will be getting that horrid mouth looking breather and if I have to modify the hood in the end, so be it. I'm not sure there's a rule saying I have to have a hood to race is there?

That is a sick kit but it's just not for me.

Heat wrap everything, put blankets on the turbos and get a heat extractor hood and you should be fine.

We'll see how it acts with the stock hood.

That's not true, the TTi X setup for the C5 doesn't have anywhere NEAR the heat concerns of this kit.

I know I can pop the hood on my car and can't tell any difference between stock and now.

Ok, cool. It's still not for me.

Tiago made 920rwhp 13psi on 427ci

It's not that hard if you do what needs to be done. I run the kit along with many others that have managed the heat well. Arnel ran the kit on his C5 and road raced the car with no issues. Each kit has its benefits and flaws you just need to know how to deal with them. I have never even burned as much as a wire with the kit.

Twin TC76's on a PTK kit will support well over 1300rwhp. The kit becomes the restriction though and not the turbos at that point.

That should be more than enough to meet my goals!
