EB Clutch upgrade

[15Boostang]

Before people start telling me the car just came out and RnD take time. I know, I'm not expecting this now lol.

Anyways, with the EB seeing over 400 ftlbs of tq from just a tune i think its reasonable we will see 440-460 tq with intake, dp, exhaust + tune. While that number sounds amazing, I'm quite concerned about how the stock clutch will hold up under heavy use.

Does anyone know how much tq the stock eb clutch was built for? And are any manufactures currently looking at aftermarket clutch and possibly flywheels?

Personally this is important because I love my high rpm downshifts and unnecessary clutch dumps, But I don't want to avoid modding my car over clutch concerns.

Anyone else drive like an idiot?

Feedback is appreciated!

Considering we just took ours apart I think we can answer your questions.

Our car has been to the track 6 times in a little over one month with roughly 50 passes on it testing different levels of power and different tunes along with plenty of street abuse and testing. With all of that abuse the clutch held up pretty good but the harder and harder I tried to leave the line the less it held up. We contacted Mcleod and they are taking our stock clutch and flywheel to develop a line of clutches for the new 15 EB.

Now this car has a dual mass flywheel and its very heavy. The clutch and flywheel assembly is well over 60lbs.

The dual mass flywheel was used to limit drive line vibration but it does have its drawbacks, it wont hold up well to higher power levels so a standard setup will be put in its place. Here is a great video to explain what a DM flywheel does.

For the normal tune only car that will run a bit more power then stock I dont think the stock clutch will be a problem but for those wanting to run them at the track with race only, high tq tunes then I think it will only be a matter of time before it goes bye bye. Its just one of those things you have to accept and upgrade if you want higher performance on a regular basis.

We had a Mcleod in our record setting 2011 GT for 2 years with tons of abuse and not a single problem so we expect what we work with Mcleod to develop on this car will do the same and are excited to see the results.

Here are some pictures of our stock clutch we removed yesterday.

Convenient timing, Ty for the qucik response

WOW that PP, clutch and flywheel setup is huge. Personally I'm looking forward to dumping some (like 30 lbs worth hopefully) of that rotational mass. Glad to see you are working on it.

Any thoughts on replacing the stock DMF with an aluminum?

I know I-4's are not as well balanced as V-x engines, But this seems like alot of overkill. That is a ton of rotational mass to deal with engine vibration, you would think engine mounts would be cheaper more suitable candidate.

Then again this is my first time seeing a DMF so maybe I am not getting the point.

Thanks again!
