what are pete jackson gear sets?

[walesy]

i was reading the SM summernats mag and there is a guy talking about pete jackson gear sets... ive heard of them but have no idea on what they are or what they do... can someone pls fill me in?

cheers, walesy

[walesy]

are they the same as gilmer drive? or no?

They replace the timing chain with two large gears top and bottom and a set of smaller ones in between.
Make an awsome sound.........but **** to run. If they dont get oil'ed properly your ###ed big time, stear clear.

oh ok cheers airstrike i wasnt gunna get them just curious on what they were... im gettin gilmer drive though... do they sound the same as gilmer drive?

There a meaner sound, but same sort of thing.

pj gear drives make the sound all the time gilmer drives only when u get the revs up

ive got a set in the garage that i was thinking of putting in. why arn't they any good?

there is nothing wrong with them just keep a spare belt because if it brakes you cant just go to the local shop and get a new one

Timing gear sets are ok as long as they are not straight cut which I think these ones are. If you've ever driven a Holden with a stuffed trimatic just multiply that sound by about 10.

All gear drives are straight cut they cant work any other way. the problem with gear drives is the vibration they pass from the bottom end to the valve train brings on early failure of some components like valve springs, lifters, rockers and such is not so much of a problem with motors that get rebuilt often like drag car engines, but with street driven motors would have to keep eye on your top end and oiling system i would think, but they sound dam tuff. i put one on the vk motor cant wait to hear it. any commy with gear drive, hi stall and low gears sounds wild!!

I actually have Gilmers on my car, and its the opposite. Nice and loud at idle, pretty loud in 1st and 2nd, after that you cant really hear them. Sounds cool though

[walesy]

wtf? all the gilmers ive heard get louder as the revs build up...

[Hillerus]

Sure it was Gilmers then? But, as im in the car, its hard to hear alot, plus my exhaust is fairly loud. Straight Cut gears will be much louder

Not all gears are straight cut....Standard timing gears are helical ie: the are cut in a curved angle. This reduces noise but on a powerful engine the gears push themselves with opposing forces. One gear goes forward the other backwards. Hence the reason for straight cut gears. Engines that rev quickly have a tendency to push one gear through the timing cover.

the thread wasnt about standard timing gears and 308' have timing chains standard any way
