hey i heard that you can get a set of timing gears that sound like a supercharger for your car i was wondering if that would be a good investment and if using the gears is better than the regular belt and if its hard to install

Gear drives are supposed to be more accurate and able to withstand more horespower than chains. They are kinda noisy which could get annoying after a while.

Mark A Shields

I have a quiet gear drive. There is a sound clip in my sig hookercompe268xe or something like that , might be able to hear it. The quiet ones aren't bad. Plus, a gear drive will last forever, no stretching, but plan to spend $150 for it.

The one I know of is a Pete Jackson gear drive and it makes that noise. But I have heard that it gets real anoying(sp) in a daily driven car. You could always get a good double roller timing chain and it should perform as well as the gear drive but without the sound.

Mark A Shields

Yeah, I would strongly suggest against a noisy gear drive, even my quiet one may get old as a daily driver, but the car isn't anymore so I can't say.

CraZ-28

Yeah, the cool factor wears off after about 6 months. Now if this is a daily driver, it wears off even faster. I've never put a gear drive on but I've helped take off 4 sets already. They can just get plain annoying after a while.

The gear drives are great for accuracy,but DONT get the noisy one.Its noisy to the point that sometimes you cant hear other things in the motor.I have a noisy in my Formula and it will be coming out.

vic_V8

all my buddies put all gear drive in their cars, now they don't like it if they have to drive it much

hndsm17

well exactly how loud is it? i mean is it so loud ya cant just play some tunes and drone it out, i mean i wanted the "semi" loud ones, just to fool people but also get some aftermarket timing shizola to help the cars preformance and stuff but i wont bother if its annoyingly loud in my last t/a i delt with a bad alternater whine for 4 months and it still didnt bother me much :lala:

Hulk0202

They cause more friction and more parasitic drag. If you want your car to look/sound cool to someone with limited knowledge of cars, buy one. Other wise spend the money on something usefull.

slickrock55

I know Pete Jackson makes a noisy gear drive and a quiet gear drive. What exactly differs between the two? (except noise level obviously)

ronterry

This one is a no brainer... If you want the super charger sound, then get a super charger.

Ron

Mark A Shields

That's the only diff is the sound. I had a sound clip with the PJ in my sig, but I don't think the file is there anymore. comp268xehooker or something like that.

Hulk0202

The noisy one has straight cut gears, the quiet one has tapered gears that mesh better.

raven350

I have had a Pete Jackson Quiet gear drive in my car ever since 97 and I love it.

They only make a quiet one for roller cammed cars.

And I would only get a quiet one because the noise of the loud one is unbearable, but I love the sound of mine.

It is an easy install.

The one thing about a gear drive is that your timing is dead accurate. There is no chain stretch.... The timing mark does not bounce around, it is as steady as a rock whether it is day one, or year 5 like mine.

There is a rumor taht the quiet ones set of the knock sensor, but this is a false statement that many of use with the gears can testify too.

I can definitely see where the noisey one could set off a knock sensor though... there is a huge difference between the two.

And the only difference between the wuiet and noisey is the way the teeth are cut as Hulk0202 pointed out.

REDZ28

My brother has the noisey one and its sucks cant hear anything under the hood from the motor except that gear drive. If you get one get the quiet one!!

They don't stretch. The teeth break, in a way that can't be fixed by simply replacing the gears after the fact. If you like the sound, yes, get gear drive. If you like longevity, get a double roller timing chain for $30. Look at the crap GM uses- it's not even a roller chain, and they can last over 200000 miles. If you are mechanically inclined enough to be replacing the timing chain the FIRST time, then chances are you'll have it apart in at least a few years for something else anyway, so you can just check your chain for stretch then. Call me old fashioned, but if a gear makes noise, there's something wrong with it.

raven350

Ah yes...

But if a gear is designed to make noise...

Noise doesn't always mean you are comprimising integrity.

91TPI5.7

Sorry guys I know this kid. He is the one who wires a stereo system with the motor running, put crome double wiper blades on his car, and duct taped his exhaust. He USE to have an 89 trans am. Now i wont upset the kids dreams at owning another thirdgen, i recomend cars to him when he is over the house.

On the tech side, Steve, if you plan on getting another car, dont make an attempt to turn the car into something it isnt. (or face the wrath of me and Kev). The gear drive idea is like putting a fake blow off valve on a honda to make it sound like a turbo ( we call that rice here). Sorry guys to sound like a douche, but all in all the kid means well, he just isnt all that bright when it comes to modding a car. I try to do the best to guide him patiently.

raven350

Hmmm lets see.

I have a Pete Jackson Gear drive on my car since '97.

I Drag race....

Us41 In Indiana
Milan In Michigan
Route 66 In Illinois

I Autocross race in Detroit and NorthWest Ohio

I also drive the car daily..

I aslo mod my own car and have touched basically everything in the car..

I don't care for cars that are made into ricers, yet I still have a Gear Drive.

Hmmm.. Maybe I prefer the Most accurate timing possible and not to mention any and every chain will stretch over time where the gears stay rock solid....

And I like the gear drive sound. If you heard the gear drive sound and a charger, either Turbo or Super, you would never confuse them. I did not go out to get it for the noise, I wanted the accuracy.

Not saying that is why he wants it, but don't go bashing the gear drive. Many respectable rides use them.

91TPI5.7

I am in no way bashing anything. Hndsm17 has no interest in modding a car to suit himself. He will take the cheapest and lowest way to a goal expecting the same results. I spoke to him personally on this. He had no idea ,till now, what the purpose of a gear drive is. If it looks cool, sounds cool, and everyone else likes it, he will get it. Regaurdless of what he wants. I feel bad for him.

RICH92RS350

Gear drives are more accurate than chains, and chains do stretch and the nylon gears on the stock sets fall apart.
The only negative (other than the noise, if you don't like that) is that you are transmitting the vibrations and harmonics from the crankshaft to the entire valvetrain.
This (and ease of adjustability) are the reasons most racers are now using belt drive setups.

flyboydave

I've had a Pete Jackson "quiet" drive for years now. You can hear a little chatter, but it doesn't sound anything like my supercharger. You really had to know what to listen for over the Rhoades lifters and B&M blower and 3.5" exhaust anyhow. But if you do get one, the only ones I trust are the Pete Jackson type. I went through 2 of the ones with the single idler gear mounted in an aluminum timing gear cover. The first one froze up after 6 months and filled the oilpan with shrapnel when the idler gear bearing seized. The second one, a warranty replacement, started making a clicking sound after a few months. I pulled it apart to find one of the idler gear teeth missing. Never again.

hndsm17

Hey Tommy i DID some majoly stupid things that have earned me a bad reputation for owning a thirdgen, but i treated it the way it was which was a piece of **** now the one im getting is actually worth saving the money for the parts, and everything now everything i do to it will be done the right way ive wanted the GTA 350 even before i bought the black POS so yeah i DID do stupid things and i ask my questions to learn not just because im a dumbass

Mark A Shields

exactly, nothing wrong with asking questions to learn. This is what the boards are for.

1982chevycamaroz28

i know i could say many things but i thik ill just keep me mouth shut

hndsm17

yeah tim you shouldent because your always negetive when it comes to **** i have personaly i think that you saying this car wont last the winter is just a sign of jealousy, but im not you so i dont know **** but its not nice to talk bad about me and this car because theres alot of **** i could bring up about yours so since weve been friends since kindeergarden i wont start anything but just try to say a nice work or a good job once and a while

raven350

Can we please get this back on the Topic of Gear Drives?

If you guys want to have it out with each other, please e-mail each other.

Thank you.

1982chevycamaroz28

hey steve talk **** about my car just go ahead. but who still has a car after 2 yrs of owning it and didnt beat it too the ground becuz it was a piece of crap. and plus the only problem ive really had was when i was puttin in the exuast and when the distributor went. and also dude u havent known me since kindergarden, i started at west end in the 1st grade and then u met me in the 3rd grade.

and also im not even close to jelous (spellin on that) on this car ur going to get, u think becuz it has a bigger engine im jelous of it. not even close, u think the car is the **** becuz it has a ram air hood, oooooooo. i dont care for it, its just a TA

anubiscougar

i have a ta w/ a ram air hood.. rofl..


so.. all in all w/ the gear drives, they are pretty good, just loud if you dun get the quiet ones.

how much power can they handle? or.. is that irrelivant? the engine i'm wanting to build will have about 650 hp.... about 550-600 torque.

flrtin1

The one thing I haven't seen talked about here in it giving false knock to the sensor (so I have seen in other posts) I don't have a computer so it's not an issue to me, 50k miles on a Pete Jackson "noisy" drive no problems

fireturd350

I also have a pete jackson noisy gear drive. I should be getting the bottom slapped together soon so the gear drive will be on it finally. Only reason why I got the noisy was I paid 80 bucks for it (ebay'd). Anyone got that sound clip of a noisy gear drive that might be interesting to hear?

flrtin1

Just for info.
There is a big difference between the noise that gear drive makes and the noise that blowers make. The gear drive noise is made from the meshing of staight cut gears the blower whine is from air that is trapped by the cogs in the belt when it goes around the pulleys

flrtin1

LOL here is a video Gear Drive ..........well sort of

flyboydave

They don't have a hp limit per se. The load they see is that required to turn the cam against the valve springs. As the valve springs get stronger for high lift/duration cams which require steeper and steeper ramps, the load on the gear drive goes up. But they're definitely stronger than a timing chain, so it shouldn't be a problem.

MrDude_1

if this is for a "supercharger sound" then i jsut want to point this out:


anyone that knows **** about cars can still tell its a gear drive.

any car guy who doesnt know the sound will ask to see it (and it wont be there)

any idiot who believes you have a supercharger by that sound isnt the kind of person you should feel the need to impress anyway.

:lala:



if you gave me a free "quiet" gear drive, id use it. its not a bad thing to have...
but its also not cost effective... def not worth twice as much as a good timing chain.

Charged350

iTrader: (1)

Yeah, me and my cuz were talkin about them today workin on my new motor, so i was gonna get a noisy one, but how loud are they, if not good, ill get the queit ones...

fireturd350

iTrader: (8)

I just bought it cause I scored mine cheap (carb anyways so no knock sensor to worry about). I plan on adding a centifugal (probably procharger) down to the road so I'll get the real sound then.

cgb

I've used both quiet and noisy gear drives.

Sounds like a Supercharger ? lol

Back when I was in high school...in the 80's and we'll leave it at that...both my buddy and I had geardrives on our cars....fairly radical big blocks..( Remember leaded gas was .60 cents a gallon ...ahh the good old days.. )

Whenever someone asked what that noise was, we always told them it was a bad powersteering pump... LOL

As far as chain stretch, miles etc...

If you don't mind the noise, then go for it.

And in all out 1/4 mile assault motors, I'd use one as a rule.

But I've got 125k HARD miles on the old 383 I built that still resides in a beater truck I use occasionally...and it's timing is rock solid with a Cloyes Double roller timing set....

Countless 1/4 blasts on that old motor....

Just my experience, YMMV

I can go back to leaded being .33/gal!

My first car was a 67 SS Chevelle $400 complete with orig motor / 4 speed , bench seat car. Needed paint, a fender, and little things.

I bought a '71 442 Ragtop my junior year of HS for $600...it needed a new top, and a good cleaning. 4 speed big block car too...

I could go on...although I never had cheap opportunity on a Hemi Car, the biggest deal I ever missed...

I had a '77 TA 4 speed / 400 car at the time.. was looking for a parts car...ran across a '74 Trans Am SUPER DUTY 455 w/ 4 speed. Had some minor rot in the rear 1/4's, and the motor was tired. I could have bought it for $500. DOH!!!!!!!!!
