I've never been on a dyno before but after i get my h/c package im going to do a clutch eventually but for tuning purposes is the stock clutch ok? Does the dyno put as much strain as launching on the road would to the extent that the stock clutch would slip?

 

Depends on how bad your stock clutch is. Why not just put a better one in same time as h/c package?

 

if your top end setup is more than 360-380rwhp that clutch will melt, slip, and basically be deastroyed. A stock car is 245-260rwhp and 285-300rwtq. Think about what your trying to get it to do?
Thats 120 more hp that it was designed for, its not going to hold that kind of power. Im worried about mine and im only shooting for 330rwhp, so more like 320rwhp realistically. Which is still 70hp more than stock.
Look into the mcloed single disk, maybe a spec???, and other companies designed for 380-400rwhp.
Than you just have to worry about the rear. It never really ends, especially if you take it to the track.
good luck

 

It should be fine on the dyno. A 4th gear pull on a dynojet puts alot less load on the clutch than than a launch would.

 

Ditto ... no need to upgrade a working clutch for a dyno run, It's not the same as a launch on the street.

When you do upgrade though, here's another vote for the McLeod single disc. I'm using it and so is a buddy of mine with a Golen 396, and both of us are happy and impressed with the disc.

I was going to go with a spec 2 or 2+ eventually, didn't look into McLeod yet, i just heard they are really expensive. But thats what i wanted to know was whether or not the dyno was going to put enough of a strain on the clutch that it would cause it to fail. I know once i get it on the street it will melt that clutch no problem but i figured instead of waiting 2 more weeks to have the money and then order it..wait.. install etc. I could just get my h/c package in, tuned, and baby it for now just so i can have the car on the road. Then once i have the money for the clutch and get it i can just pop it in and start having some fun.

On the SPEC website the stage 2 is rated well over the TQ I plan on achieving, so why does everyone say its only worth it for 3 and up?

 

No. In terms of clutch strain, a dyno pull is like racing from a roll in 4th gear. It will vary a little from one dyno to another. A properly calibrated Mustang dyno should be very close; most other dynos will be easier on the clutch than the Mustang dyno would.

 

I saw a statement on Mcleod's web site that a dyno run puts a lot of strain on the clutch. Might want to address this first especially if it were to affect the numbers.

 

yea maybe i'll just wait to be on the safe side

 

That's BS. A dynojet is just a 2600lb rotating drum, vs a 3500-3600lb car + drag.
