All part of the plan , turbo , lots of clicks. Blow it up lots of clicks. Rebuild with proper CR. / internals, lots of clicks. End result 700 hp, lots of clicks. Blow up trans, lots of clicks. Are we seeing where this is going ? But all good stuff !

I do like the wheels.
LT1’s handle boost just fine.

The problem is that the C8 just can’t be tuned yet. Until then, these TT kits don’t make sense.

Atmospheric changes in the combustion chamber from forced induction CANNOT be compensated for without proper fuel management. If you cannot access the computer that controls the fuel air ratio then you are only asking for trouble. There is no compensation for improper detonation at that point.

You're just jelly because you don't look 1/10th as good as she does.

The upside Is that these You-tubers will make the mistakes and save all of us money.

I didn't say they did. Read my post again. The ECU can adjust for some mods because of changes. I talked about exhaust changes, which in the C7 would have needed tuning, do not require it in the C8. Obviously, some turbo kits take sensors out of their range and readings out of the tables, and beyond the injector ranges when they reach a certain fuel flow (power level). On a side note you do know the last ECU had the capability to manage twin turbo systems already in the base code. This one will likely have that too, if they can get in and flip the bits.

I view it as an interesting, completely blind journey of build, blowup and try again - all without any clue on how to engineer the changes or ability to control/tune the engine. Very messy but somewhat interesting.

I would expect no less from someone who strapped her car to a building in order to be able to do a burnout.

It's a recipe for disaster, even a Mclaren 720S only runs 8.7:1, NO production car is running 11.5:1 with twin turbos, was never designed for it.

Half of you people on here wish you knew 1/2 of what she does. So much hate from a bunch of grumpy *** men.

I skimmed through the video because I couldn't stand to listen to her the whole time. Did they blow it up on the first pull in the parking lot or was it at least on a dyno first? The part where she said the failure was because of the gas in California told me everything I needed to know about her knowledge of cars.

Ha. My guy used to put a $20 bill in the tank to make it pass. A $5 bill never seemed to work, but the $20 always did for some reason.

but they were able to tune the engine to a degree same as LMR have managed to do a few tricks.. Even with a 100% tune it still would have gone bang

She blamed the melt down on the fuel being from california. I watched a bit more and she said with race fuel on the dyno it was good but as soon as they switched to 91 pump gas it melted down and she seemed confused. When she was going through options for what to do next she considered just putting a used piston and rod in and running it. Those two statements tell me a lot about what she knows about cars.

I dont know everything but even I know that 11-1 on pump gas with twins will melt parts. That and one used piston in a forced induction setup is a **** poor repair.

Its not about being grumpy old men bashing her just because shes a girl. Its about basic mechanics.

Yet according to many people here she is extremely knowledgeable about cars and everyone here is just jealous of her vast knowledge, lol.

I suppose it's good for "us" to see a beautiful, highly desirable, brand new C8 trashed before your very eyes with run away twin "turboskies" (good lord, can we really use a little less technical jargon?) and other crazy hi-jinks, as if you get tired of watching the rebuild, there's the nice rack to hold your attention until the next bit comes along.

But one thing our modern video age does do, is help solve some of life's great mysteries that were once left only to the imagination. Like when you are hunting used hot rods, and the "clean, one owner" car you go to look at is just a ragged out, rattle trap, about ready to break in two, and you wonder just what the poor car had been through to get in that shape....Now, you know...

racing creedo If you don't break it, you aren't pushing hard enough

It's a car and she has the cash to buy it, blow it up and fix it. Nothing I haven't done (not quite so ham fisted but close), and I'd rather her blow up her vette and me learn than vice versa

Good to see ladies getting involved in modding and hot rodding. I think some direct port alchy injection would be something to try to add fuel once the WB runs out as another "blow it up" type experiment

with the wb the computer would start pulling fuel if it gets too rich and you'd be running a higher percentage of alchy It will likely code and phone home but it might not blow up
