Bad Driving Habits (M/T)

Vaughanabe13 · 02-21-2012, 03:00 PM

While we're on the topic of MT, can someone answer this question for me. I feel dumb for asking...

In the movie "Back To The Future" there are several scenes where you see Marty in the DeLorean doing a fast takeoff. They show a shot of the pedals and what he does his release the clutch super fast and jam on the gas right after. I feel like that's not possible and the car would stall in real life. Is this just a movie magic thing or is really possible to get a fast start that way by whipping out the clutch and jamming on the gas like that?

in the future all is backwards.

Thanks for the good advice, guys.

No, I don't really treat it as a contest to see who can start at the lower RPM, I just want to drive my car correctly. Seems like I need to get rid of the "mustn't slip the clutch" mentality and give her a bit more gas on normal takeoffs.

Thanks!

yah, unless you're smelling the clutch every time you're not smoking your clutch.

Bad habit that i used to get away with in my S2000: Down shifting into first gear at 5mph when needing to accelerate from a slow roll.

Depends on the car. On my mustang I can actually start the car moving with no gas. I've seen the same thing in vettes.

most street cars you can

The z can be started like that too I think...very very slow engage of clutch though.

And to Augustus, don't worry you can safely rev it up to 1500 rpm even and engage it at that point if you want a bit smoother shifts.

Not with a straight clutch drop. Maybe if you ease into it.

Unless by "most street cars" you are talking about all the automatics

Yes though very slow engagement of clutch will allow that. (7-10 seconds in my scion)

kenchan · 02-21-2012, 04:54 PM

yah, one thing to remember is how you engage 1st gear from standstill will also affect how you shift into 2nd gear. if you give a nice rev and smoothly engage 1st, build healthy speed, then shifting into 2nd will be easier.

if one bogs 1st gear and applies more throttle to make up for the slower start, one will need to lengthen wait time for flywheel spin down into 2nd gear. hope that makes sense.

Thanks for the advice.

So at what RPM does excessive clutch slipping really start to cause damage to the Z's clutch?
