High hp guys, I need your help!

I have a built LS2 engine + 4L80E with Yank billet lockup TC and will be at about 1500hp, maybe up to 2000 hp with the twintrubo setup (2 x Garrett GTX 4202).

I found 3 flexplates but am not sure what to use:

TCI flexplate (heard of it braking)
ATI
Meziere

Anyone knows of a high hp application where one of these works perfect without braking?

Or are there even better (stronger) flexplates available?

I donīt care if it costs some money, I just want to buy the best available.

A billet flexplate is the only way to go IMO at that HP. I would vote for the Meziere.

Austrian Vette

Ok, billet.

But what brand will hold the up to 2000 hp, lot of torque (which is even more important) and the hard drag launches?

Any real life experiences would be great.

(I know there are not too many 2000hp cars on here, but some are close, I think).

I agree with Vince. The Meziere billet flexplate is the only way to go with that kindof horsepower.

Austrian Vette

Hearing that from RPM is a good reference.

(BTW, I have my Corvette heavy duty diff with quaife from you guys).

Ayone else recommends the Meziere for my high hp setup?

Would love to hear it from someone who runs it in a similair setup.

i run a meziere but i am no where near that horsepower. i would also call up meziere and ask them if they feel theirs is made to handle your needs.

Austrian Vette

I have allready contacted them.
and they said it should handle it.
But to be honest, they didnīt sound very convincing.

Its bc we are sue happy idiots over here and people don't want to put their word on anything that could land them in court. Its a damn shame actually but we wont get into that......

Although he doesn't do it currently, Vince B ^^above has been building performance transmissions for a long time. Most around here know him as his previous screen-name: Vince@FLT. Sometimes you are getting expert advice and just dont know it.

Austrian Vette

Thanks for the info.
I do understand.

Well, I DO KNOW that Vince worked at FLT.
Thatīs because I read the thread that he has a link to on his posts.

I do know Chuck since about 10 years and ALL of my trannies are built by FLT.
Never had one fail.
Donīt know if Chuck built my tranny himself, maybe Vince built my 4L80E with trans brake that I got in November and that will be used in my car.

As RPM and FLT guys recommend the Meziere and I myself would have choosen it, too, I think thatīs enough to decide for it.

Thanks a lot, guys, for helping me on the decision !!

Which Meziere flexplate do I need for the use with a LS2, Yank TC and 4L80E?
There are 2 available (flat and dished).
And do I need a spacer between crank and flexplate?
