TCI Flexplate or stay stock? Just curious if the TCI flexplate is worth it?
By end of February I will have :
382 LS1
G5X2 cam
Comp R Lifters, Comp 977 Springs, Yella Terra Rockers
12 bolt w/3.73s
And I do plan on spraying a 100 shot dry...
My stock flexplate has 45k on it... most of that time was spent w/either a SY3500 or Vig3600 TC
TIA

I will be upgrading my stock 99 flexplate to the TCI just because I'll be in there for my new Yank PT4200. The 98 and 99 cars have a stronger flexplate than the 2000+ cars. FYI. It's lighter by a few lbs. and will give slightly better throttle response and top end momentum. 
,but what the hell.

My TCI Flexplate weighed in at 7lbs and it was HEAVIER than the stock one, I'd say the stock one weighed 3-4lbs....
In an A4 car you want a flexplate to be a little heavy but not too much.
I like mine alot

If it's heavier, why does TCI advertise a lightweight design and quicker engine response? Someone's wrong here. Are you sure the stocker was lighter? What year was the stock flexplate? 2000+ I hope.

The aftermarket flexplates are thicker and heavier. The car should be just as responsive with the aftermarket unit. You really won't be able to tell any significant difference between them.

Have you seen the pictures of it? they drilled massive holes in the thing to reduce the rotating mass but still retain stuctrual integrity....
That is a lightweight design.
as far as quicker engine response is concerned the only thing that might be said about that is the fact that the heavier weight but decreased overall mass would equate better momentum and allow the engine to rev more freely.

Well, If the pulled the weight in toward the center of the wheel the engine would rev faster even if it weighed more.
I was really hoping it would be lighter overall. In my opinion heavy is never good. Especially when it comes to reciprocating weight.

A big mac and a large fry will slow you down more then using a SFI flexplate. If you are looking at it as a mod to gain anything, that's not going to happen. It's mostly a safety item and you either need it or you don't.
