Does Quaiffe make gearsets for the Impreza transmission?

Digital_Boy · 10-27-2000, 07:57 PM

I received an email from a vendor, and in it they stated that Quaiffe makes and sells full synchromesh gearsets for the Subaru transmission. Seems to me that with the quality and strength of Quaiffe LSD's, that their gearsets would be a hell of a lot better deal for street driven turbo'd RS's than a full or half dog box.

Soon..

Two types..

Syncro and non synco versions..

Hey Digital,

RalliSpec has synchromehs and non-syncromesh Quaife gearsets listed on their web page. Just a bit pricey though...

Jay, how much for us I Clubbers? I'll pay the extra oomph for Quaiffe quality.

MikeYOX · 12-19-2000, 03:01 PM

What exactly is "syncromesh"?

Turk · 12-19-2000, 03:55 PM

Beat me again, Rallispec sells them

5 grand!! I was preparing to pay $3000 for a BPM gearset but that is just nuts!

Jay - How much for the synchros to go along with that Stage 1 BPM gearset?

cvalle-sd · 12-19-2000, 06:08 PM

Syncromesh gears have a helical or angled cut - the teeth arent parallel to the axis the gear spins on. They'd look like this:

///////

this makes the gearbox quieter, as the teeth don't "slap" together as loudly as the gears drive one another

Strait-cut gears are cheaper, simpler, and ARGUABLY stronger - they look like your standard conception of a cog or gear wheel. They're pretty much de rigeur in race cars that don't have stock-gearbox regs. As most race cars have easily replacable gearing - to accommodate different track needs, engine tuning, etc. with many ratios to maintain, a big box of the straight-cut gears are a lot cheaper. they're also lighter, as the teeth of a helical gear have to be longer to reach all the way across the gear wheel itself - more metal, more weight.

An update... I've been doing resarch and it seems that Quaiffe doesn't actually produce any gears for the Impreza yet... I understand they advertise a part, and then wait for customer responses to determine if it's worth their while to make them. Soooooo, until I actually see a set myself, Quaiffe gears are vaporware AFAIC.

That said, I also talked to Paul Guard, purveyor of Porsche gears, and he believes he can turn out gearsets of any ratio you desire, as strong as or stronger than MRT gears, and cost competitive. Have to wait and see what develops there.

8Complex · 12-20-2000, 08:01 AM

Cool, see what he can do for a full syncro'd setup. I'm gonna need something this summer or so...

MikeYOX · 12-20-2000, 09:41 AM

This is what the information representative had to say when I inquired about the Legacy/Impreza gear kit:

Mr. Richmond,

The gearkit sells for $3,875. Synchromesh refers to the type of gear
engagement. All street cars have synchromesh gearboxes due to their quiet
operation and ease of use. Race cars use dog engagement which do not use
synchronizer rings. This form is much noiser (not suitable for street use)
but has the advantage of greater strength as well as not having to use the
clutch to upshift.

Regards,

Ralph Hollack

Could someone expand on that last answer? I'm still trying to puzzle out gearboxes and trannies. Why exactly is it called a dog gearbox? And from reading around on MRT's site, I got the impression that not all straight-cut gears are dog gears. Why are dog boxes faster to shift and why is no clutch needed to upshift? And when they say loud, what are we talking here? And lastly, does anyone feel like putting together a transmission 101 for all us folks a little fuzzy on the details?

<a href=http://www.howstuffworks.com/transmission.htm>manual transmission explanation</a>

<a href=http://www.howstuffworks.com/question522.htm>straight-cut gear explanation</a>

i'm sure someone else will pipe up with an explanation of dog gears. i just don't feel like doing any more web surfing today - there's a blizzard on the way here in new england and i'd rather be out driving in the snow.

later!

dunny · 03-04-2001, 07:34 PM

Thanks for the reply! Unfortunately it's 10 degrees (celsius, that's 50 Fahrenheit for those saddled with the imperial system

) here in Vancouver. So dog gear systems mean no syncro right? But most companies also mean straight cut teeth when they say that? Does anyone have either a half dog-box or full dog-box tranny in their car? Theory is good, but how do these things drive? They sound pretty loud. Am I right in saying they're more for racing or are these streetable systems if you're looking to upgrade the transmission?

Good night everyone!

So those gears would look like the ones on my RM250. That would be kinda neet, smashing into 2nd and 3rd without a clutch.

If any of you have seen a dirtbike tranny, you have seen the gears they are talking about.

DeliciouSpeed · 03-04-2001, 10:44 PM

And as for sound, imagine if all the gears sounded like reverse. Cool huh, for a while anyway.

dunny · 03-05-2001, 08:46 AM

I took a look at my first one and I realize that was quite a mouthful of questions! Apologies for rambling on everyone.

randy zimmer · 03-05-2001, 11:42 AM

gearbox questions...
straight cut and helical refer to the teeth that always mesh together with the lay shaft (not reverse).
A layshaft looks like a christmas tree of gears all connected to or a part of a single shaft.
Syncros and dogs refer to the way that the gears (1-5 or 6) are selected and then connected to the shaft so that the power is transferred.
All the forward gears are on a shaft and when in neutral, spin on bearings. The shift lever connects to a fork that pushes a sliding ring that is geared to a hub that is permanently geared to the same shaft.
When you push the lever, the ring engages teeth (not the same ones that engage the layshaft, but other teeth on the side 90 degrees different)on the spinning gear and they connect the gear to the ring to the hub to the shaft and the car will move.
When you engage the spinning gear it needs to start spinning at the same rate as the hub or it makes noise. Synromesh is the way that a brake (syncro) starts engaging the hub and in turn, starts spinning the gear at the same speed so that the gears will mesh without noise. (a worn syncro (brake) can be beaten and gear noise results).
Dogs are a real coarse type of tooth (like 6 or 8 on a gear) with voids between them so that the teeth will drop in easily. There is no brake so double cluthing helps.
Once the gears are spinning, the dog teeth drop in easier. Close gears are also a help as the spinning speed differences are less.
a "dog" looks like this -
[
]
[
]
[

[
]- in a circle.
There are different type of syncromesh designs but they all are a form of brake.
Hope this helps.

Kaaz also makes gear ratio sets for the Subaru but only synchromesh. Probably cheaper though.

Damon · 03-06-2001, 02:54 PM

anyone with questions about trannies (not transexuals

) go take a peek at the new SCC. their article about the Impreza build up is about...drum roll... TRANSMISSIONS! the killed 2nd gear in the car, so they got BMP's half dog gear set for their subie. there is a sidebar article explaining all the questions that have been asked.
