Ive read about this on wikipedia and other sites, but I am confused as to how its done. The idea is if you have a dead battery someone can give you a push as you are in 1st with the clutch to the floor, and then you release the clutch and it starts the car??? Has anyone done this? Does it work? Just wondering because it might come in useful one day and I dont want to be left in the parking lot if noone has jumpers

dickerdieter · 04-18-2007, 09:50 AM

1. just get a set of jumpers

2. because you have forward momemtum, when you drop the clutch it will getthe engine moving and therefore the alternator, which will provide your engine with electricity, allowing your car to start and if you leave it running your battery will charge. this is assuming that your alternator is good. someone correct me if im wrong but Im pretty sure that this is how it works

cxrock16 · 04-18-2007, 09:51 AM

yeah its called compression starting.. youve never heard of it?

DropTopChevy · 04-18-2007, 09:51 AM

The hard part is getting the car up to like 15mph if there is no incline around. But it works. I did it a few times with the camaro when i was having trouble with the starter.

CleanNeon98 · 04-18-2007, 09:54 AM

wow thats decent..wiki says anywhere between 5 and 10 miles per hour is good...is it a clutch engagement or a dump you have to do...il have to try this out

You dump the clutch like you have never dumped it before. I usually did it in reverse cause i was rolling backwards out of a driveway.

Loserkidwac · 04-18-2007, 10:16 AM

LOL I had to do this in my CRX all the time because it just sat for long periods of time...yea I use second gear and just get a good roll going on and you will be able to start it...The battery is only really used for starting the car, spinning the starter and all so pretty much you are using the cars momentum to turn the engine over...I wouldn't make a habit of it but it does help when you are in a bind!!

LOL I can remember pushing my friend's 1988 something F-150 up a big hill to get his truck to start. Thank god it was a manual.

Broken5hift · 04-18-2007, 10:30 AM

second gear drop FTW

S4toSTI · 04-18-2007, 10:39 AM

This is not a new thing haha.

teh DIRT · 04-18-2007, 10:41 AM

5mph is fine I think. I remember pushing 96Stang's old 5.0 mustang in a 7-11 parking lot. I pushed him towards the street and was like "if this doesnt work, make sure you stop before you get to the street" haha

CleanNeon98 · 04-18-2007, 10:53 AM

well now i know...im gona try it out somewhere to see if it really works and how. its not a new thing, but its new to me

markley02 · 04-18-2007, 10:54 AM

I cannot count the amount of times I did it to my M3

uurxin · 04-18-2007, 10:57 AM

it works much better if you are in 3rd gear.. i have used it all the time.. dead batt in philly... get some guys to puch me and wala .. im going again.. though if you have a jumper.. use it

Dave · 04-18-2007, 11:08 AM

the ratios are more favorable if you try it in reverse. a good hard shove will start 'er

CleanNeon98 · 04-18-2007, 11:22 AM

is this bad for the car? compared to a jumpstart

markley02 · 04-18-2007, 11:25 AM

I have never heard of anything directly breaking due to this, but it does put more stress on the car than "average" driving or jumpstarting

Dave · 04-18-2007, 11:36 AM

wears the clutch and motor mounts. otherwise no

turbo4g63 · 04-18-2007, 12:58 PM

i did it once, but not on purpose....i blew an IC pipe and i was almost back to my friends house, car stalled and i was already going down the hill, so i just dropped it in 2nd gear and let the clutch out, the car fired up and i got it home
