I am thinking of buying a gear drive this guy would sell it to me for $85 with everything he had it in his 350 and is telling me if i want to buy it i have a 350tpi and i am thinking of getting it would it fit in it.

 

yes it will fit but there is no point, also the noise created sometimes is picked up by the knock sensor, its best to leave gear drive for race cars.....

 

What he said ^^^^ :-)

 

Is there any way i could take the knock sensor i like how it hears for i could surprisse people

 

Gear drives only sound good when they're in someone else's car. When it's in your own car, they're very annoying.

I had a gear drive in my car for one day. I yanked it out and put a good chain back in.

 

What is the advantage of a gear drive? Much lower failure rate?

 

I want to surprise people when they hear the whine and i am in a club and they all have gear drive but they are 70's car

 

If it's important to you, just unplug the knock sensor, run premium, and keep an ear out. Be aware that there are noisy gear drives and quiet ones. If it's used make sure it's the right one.

 

bottom line is fuel injection and gear drives dont mix. so no u cannot put gear drive on ur TPI 350, swap to carb and u can but thats really shooting youself in the foot....

 

come on man dont give people advice like that, they really run their cars into the ground, i know ur just figurein hell this retard wants gear drive so **** it heres how to do it, but it will make u look bad sayin advice like that.... and to the OP how old are you? your obviosly young and naive. Well help you figure out to make horespower all you want without makeing ur car into a POS but please dont go fast and furious on us, lets help u make power and not "sounds like he might have power" bs....

 

It's kinda like like the coffee can mufflers on Civics, it's not my thing but if that's what they want who am I (or you) to judge? In a practical sense it's not going to really hurt anything if he doesn't let it knock. The TPI is not going to care how his crank and cam are connected as long as it holds the timing.

 

Being fuel injected has nothing to do with running a gear drive, and yes he can put it on there.

 

If you just want to hear gear whine I got a POS 10-bolt you can have.

 

well as long as people ask us for how to do something they are going to recieve our advice and our criticism. IMO you should never recomend people to disconect sensors just so they can run a pointless part, lots of things could cause an eninge to knock and with his sensor unpluged it COULD lead to engine failure. All just so he can MAYBE fool someone into thinking he has a supercharger...What happens when someone finds out he doesnt hell look stupid. Its like runnin around bragin bout havin a big johnson, what u gonna do when a girl takes u up on an offer to see how big it is. Your gonna feel mighty dumb lol Dont fake hp make it. Just what we need.... John Doe: "Man me and my R iced out Civic just blew the doors off that camaro!!! And man that thing had a supercharger did u hear it!!! I must make like 1000hp!!!Hondas for life dude!!!"

 

You dont need to disconnect the sensor depending on what exactly you use and how you install it. I even know someone who used to post here that ran a noisy drive. So if you want to give out bad advice, keep telling people it cant be done.

 

The only knock relevant here is spark knock. He doesnt need to unplug it, many people run them with FI. If he wants it, let him have it. What rlcers think shouldnt be top priority list for car modifications.

 

Surprise people? The only surprise is going to be how bad they beat you seeing as they though you had a bad *** race motor because they heard a gear drive, when really it was just a stock TPI motor with a pointless gear drive. AKA, all bark and no bite.

If you want to surprise people, spend your money on something that will actually make your car go fast. Then, when your engine sounds nice n' stock, they will get their surprise.

 

Amen to that.

I'd much rather be a sleeper than a poser.

 

Side note: sort of related, has anyone actually ever recorded what the knock sensor picks up if a gear drive has been installed? Kind of curious...

 

Record what exactly?

 

Knock counts. I see everyone say the KS and gear drives don't mix. Never seen anyone put up actual KS data.

 

Alright can you guys help me out how to make my car faster would you guys recommend me to just replace the stock chain or buy a double for the engine and what other upgrades are good to do to my engine i am new to this so i am only learning my friends that is a mechanic and he has rebuild 350's for 25yrs. and he is the one one who told me aout the gear drive but he doesn't know i am going to put a tpi and i didn't know it's a problem and also he told me to buy some plastic gage were could i buy that.

 

You don't gain any speed by any form of timing set over another. Just get a double roller.

 

If there's nothing wrong with what you have, then just leave it. Don't go tearing your engine apart if you don't need to, this is how you start messing things up. As far as making the car faster, start doing some searches on 3" exhaust and headers. Rear end gears (3.42 is a perfect ratio) help also.

 

if im not mistaken the only point of a gear drive is for absolute reliability and never having to replace a timing chain

 

A gear drive removes all lash out of the system, and also provides for easier phasing of the camshaft.

 

I had in the past. Kind of pointless to put up a log file that shows no knock counts. If you have a PJ "quiet" drive installed right, it wont set it off. Tim Burgess from here was running a PJ "noisy" drive without problems.

 

A friend o mine runs a pete jackson "Noisy" gear drive. He had to disconnect his knock sensor due to it. Now, does that have to be disconnected all the time? Who's to say? Maybe. I just know that I cannot stand to ride in his car due to the annoying whine from the gear drive (ESPECIALLY with the t-tops off!) He likes it, though. Me personally, I like the sound of a deep-toned exhaust, but maybe thats just me... Plus my exhaust system actually made the car a little faster.

 

How much are the double roller for

 

Let's get back to first principles here:

What exactly are you trying to accomplish?

 

Aha, the million dollar question!

 

 

I am wanting to know whats better to put to replace the timing chain because they told me it is not that good and then they offered me the gear drive so iwanted to know if i should just put a doulbe chain or the gear drive i am just gonna have the car for daily driver to school and to work thats all..

 

To be honest with you, sounds to me like they've got a gear drive they're trying to unload on somebody.

Can we assume:
1) The car is in running condition at the present time.
2) There is nothing specifically wrong with your timing chain.
3) Some day, you'd like the car to have more power.

If 1, 2, and 3 are "yes", that gear drive is about Step #143.

Step 1: Tune-up - spark plugs, spark plug wires, distributor cap and rotor, air & fuel filter, O2 sensor, fresh and regular oil changes.

Step 2: Sub-frame connectors (should be part of any 3rd gen, IMO).

Step 3: Exhaust - headers, high-flow cat, cat-back.

Step 4: Polyurethane suspension bushings and mounts all around.

Step 5: Camshaft upgrade. This is where you buy a new double-roller timing chain set.

Step 6: TPI upgrades.

Step 7: Head porting.

See where this is going? You don't need that gear drive where you're at.

By the way, your engine has a roller lifter cam (if it is a factory 350 TPI engine). The chances of that gear drive being for a factory roller lifter cam are pretty small.

 

My 2 cents: Most engines that are of the extreme nature that require the precision timing achieved by gear drives, typically go with belt drives (at least the one's that we put out). Everything else we recommend a high quality double, such as a Cloyes or Comp. For us, gear drives sell simply because they sound cool. That's all.

How did they determine that your current timing set "was not that good?" If it actually DOES need replacing, as everyone has agreed on: go with a double roller.

 

Alright i will get the double what kind do you guys recommend and does the kit come with everytn=hing to install it

 

Cloyes makes a really nice one.
www.summitracing.com
www.jegs.com
If I remember right, they both carry cloyes...

 

No. It will have a chain, crank gear, and cam gear.

You'll need gaskets for the water pump and front cover, and possibly oil pan. You'll also need a harmonic damper puller and installer (sometimes, but not always, contained in the same kit), and gear puller.

We still haven't established why you are replacing the timing chain.

 

My chain is not good any more or should i just replace the chain and then later on replace the cam later around how much are the replacement chain

 

How do you know the chain is shot?

 

He told me it was so i guess and he recommends me to replace it

 

Is this the same guy that tried telling you that you needed the gear drive? Sounds to me as if they're just trying to make a quick buck.

If you hook up a timing light, is it semi-erratic? Did they remove the distributor cap and hand rotate the engine back and forth to check for slack in the timing chain? 2 signs of a timing chain that's actually worn.

 

in the words of tom and ray,
bo-o-o-o-o-gus

 

the engine apart i already bought the chain i just replaced it i ended not buying the gear drive i will post maybe next month when i have money for you guys could help me
Thank You guys

Rodolfo

 

You never once, in all this discussion, said that. You talked as if the engine was running. Little details like that are rather important.

Glad this is resolved.

Whew!

 

I will explain better next time if i remember i am going to add you as my friend five7kid is that alright

 

I have a Pete Jackson "quiet" gear drive in my 383 and everytime I start the engine I get at least 30 knock counts because of the gear drive. Sometimes my scanner reads 64 knock counts at startup. At idle I get no counts and at WOT I may get 2 or 3 but that's pretty much it.

 

I always get a shitstorm of knock counts on my TBI when I first start it up, but it's from the starter gear engaging the flexplate. I don't have a gear drive. Sounds like what's happening to you.

 

I never thought about the flywheel teeth. Good point! I also just realized that all of my knock tables in the prom were set for a 305 knock sensor and I have a 350 knock sensor.

 

I am going to put it on a trans am but the engine is from a iroc would the computer work or should i leave the one on the trans am its a 305 tpi
