MPI got gear.

If you have a good ear, stock forward gearing can also be heard.

 

[Metal MP5]

you can def hear it when slowing down if you leave it in gear and leave the clutch

Yeah I have to find all the stupid little squeaks that 90yr old women heard, once, lol. You have to have a good ear.

 

[tekkie]

and this company would be who?

prices prices I want to replace these things while I install my new clutch-flywheel - lsd

DSS axles they make, are just the stock heads with 626 shafts from what I heard.

There is a shop in Ontario that makes billet axles. Would have to get more info on them.

I agree, I took mine into the dealer for this noise.. thought it was a problem.... guess not huh!

 

[CustomMSP]

You can hear it that much more if you have an AWR rear MM.

Around 50 to 60 mph in 5th if I let off when the car is warm I can hear it very clearly.....but if that's normal I'm not going to worry then.

I'm gonna guess the price around $2500.

To educate those who want to know, here is a copy/paste:

"[font=Verdana, Arial, Helvetica, sans-serif]Spur gears have straight teeth and are used to contact parallel shafts. Spur gears have a high pitch whinning noise associated with them similar to the noise reverse gear generates.[/font] [font=Verdana, Arial, Helvetica, sans-serif]Helical gears are used in standard factory transmissions. The teeth on Helical Gears lie along a helix, the angle of the helix being the angle between the helix and the pitch cylinder element parallel with the gear shaft. Helical gears can connect either parallel or nonparallel nonintersecting shafts. Such gears are stronger and quieter than spur gears because the contact between mating teeth increases more gradually and more teeth are in contact at a given time. [/font]

[font=Verdana, Arial, Helvetica, sans-serif]Helical gears have one disadvantage when compared to spur gears. When they are loaded a side thrust is created that must be absorbed in the bearings."[/font]

Would all 5 gears need to be replaced or could you just replace some?

What gears sees the most abuse? To my knowledge no one has had any gear problems yet.

I personally would love a larger 5th gear.

 

[Metal MP5]

Focus stripped a gear this week

logically, i think 3rd and 4th are the ones taking the most abuse ... i don't think 1st gear will ever hook hard enough to break, same with 2nd gear. I guess they will always spin before breaking .... and i dont think anybody will boost 20psi in 5th =\ so maybe there could be a less expensive option of just replacing 3rd and 4th ?

does that make any sense at all ?

 

[4001]

Really dont know much about this at all so please bare with me but can someone explain what the advantages were if we were to get one of these sets in a heli-cut. Would the notchiness of 1-2 be gone, is it like "forging" the internals of an engine so that the tranny would be able to handle more abuse. Id like to just understand more about this so if you could point me in the direction of some info to read about it or give me a crash course in helping me understand this Id apperciate it. Also would this basically be used for someone who is looking to go for huge numbers?

Thanks guys

 

[terbow]

I thought first takes the most abuse of any gear. Since its the one that gets u goin. Maybe im wrong (dunno)

 

[vindication]

I would change first just so we wont get that much wheel spin when we up th hp. It really doesn't take that much abuse. I think forth takes the most right? And I'd make the final drive so that we dont cruise at like 3.5k at like 70mph.

 

[mazdaowner123]

I'd agree on a longer first gear for less wheelspin, and a longer 5th for more top speed and better highway cruising. I could see a well modded msp hitting the speed limiter on the straights on a road course. Seems like it'd be best to go ahead and just do them all heh. Never have to worry about it.

you guys are ecu speed limited? damn. teh suck.

 

[Metal MP5]

you're not ?

my engine cuts at 220km/h (137.5mph)

 

[changedman]

never had a cut, and i've been upto about 132, but last year hit 136 no problems... except getting close to redlining it

 

[Metal MP5]

132 and 136 that's what i mean, our engines supposedely cut at 137.5 (220km/h according to Mazda canada)
