Anyone running one? Was thinking about switching over to one because I kinda like the whine they make, sounds like a blower. But are there any benifits to running one? Anyone have any experience with them? Will they outlast a timing chain? Will my timing be more precise with one or is a timing chain better?

I'm running run in my motor, it has advantages over timing chains like you've asked. #1 key factor, No chain to be stretched, therefor timing isnt affected by it. I absolutely love the whine it produces, i just wish it was alot louder. So people put one on and then hate it, so they take it off. Louder is always better though. IMO

I think they make a quite one too? I would choose the noisy one myself, I heard one on a 71 camaro going down the road before and the thing just sounded so tough!

urmomshot77

yeah definatly. i got one on my motor and no complaints either. They make a "quiet" and "whiney" version..... I just wish they had a "REALLY FUCCKKKIN Whiney" version

4playta

Roflmao...I would buy the realy fucckkking whiney version too

I to love the whine they make. I have been running a loud one for more than a few years. I think you get a more of a precise timing with a gear than you do with a chain.
Just my 2 cents

I had one on my 1980 Camaro and ran it for 12 years without problem but there are a couple of things you need to watch -
1) Don't try to run one with a EFI computer that has a knock-sensor the noise will read as detonation and retard your ignition.
2) They do transfer crank harmonics directly to your valvetrain and can shorten the lifespan of your cam, lifters, and rockers. The more power you make the worse this effect is (my car made only about 300 hp). This is why Nextel cars use Jesel timing belts.
If you plan to run one make sure you use a top-quality balancer

There are no gains to be had over a good chain. They're not intended for street use due to the added harmonics in the motor, as well as the lesser life expectancy.

- They are only a detriment to hp on a motor that doesn't need it.

I wouldnt run it on a car that see's a lot of driving...It does add about 50 hearable HP..

Shagwell

it adds the noise, the stickers add the hp

There's entirely too many people who havent had any problems, and a single one I know of that has. I wouldnt worry about it with a PJ Quiet drive. Noisy drive... you're on your own. But, there's a member here using one with no problems.

I had a Quiet Pete Jackson installed on my mostly stock 5.7 while it was apart last summer. The back of my car makes plenty of noise, why not a little in the front (minus those darn fans)? I would have went with the loud but I didn't want it to whine as much as the people who don't like them. :P So I am really happy with it. No known knock issues, nor did I find anyone on these boards who had a knock issue when I searched last summer. Keep the car in first in a parking garage for the full effect!

i was thinking about getting one for my 350 im building but i want the noisier one. i was wonder about the knock sensor tho cause im gonna be using tpi. could i get rid of the knock sensor?

yeah thats what i mean 50 visual HP...

A magazine tested chains, belt's and gear drives awhile back and found almost no difference, they even advanced and retarded the cam timing 4 or more degrees and found little difference, so it's up to you, I personally think that when I hear a blower, I want to SEE a blower, not just a noisy engine with a hidden noise maker. A good tru-roller chain is the way to go.

Shagwell

Agreed, except one thing; cam timing makes a large difference in an engine's output. It sometimes doesn't change the peak numbers much, but it makes quite a difference in where those numbers occur. We use-to advance or retard the cam in super comp to make it run on the dial. A couple of degrees could easily change the car 2-3 tenths.
- I realize you're just quoting a mag test though.

DartByU

Yeah, I believe they were just checking peak HP, I'm sure the average HP
could make a difference in track times.

strokermotor91

There might have been no difference, but i can vouge that the chains stretch and throw off the timing. Gears do not.

Apeiron

Chains don't stretch, they wear. So do gears.

strokermotor91

Well then they must wear pretty darn good then. I had one on my 396 with about 1 1/4" "wear" as you put it.

Apeiron

A cheap non-roller chain elongates over time because the pivot points between the links wear. Only a few thou each, but over the length of the entire chain it starts to add up. A good double roller chain will last as long as a gear drive.

strokermotor91

Cool, I'm not knockin on you Apeiron, Thats just the way i've learned. Basically its the same thing, if the pivot points wear the chain appears to "stretch.

I am running the "quiet" gear set on my mostly stock 350 and it doesn't affect the knock sensor. It is pretty loud though for the so called quiet one, which I have a feeling may get old after a while. Aside from that, if you like the noise, go for it...if you don't, stick with a good chain. Chances are you won't see the day either wear out on whatever motor you're putting them on...
