I am talking about built h-series motors that will be taken to 9,000 or higher.

We know...
H22 trannies don't like high rpm shifts.

So...
How are you all dealing with this problem?

- Coating the synchros?

- H2B plate seems like a good idea but (in preludes) the shift linkage would be a big problem not to mention loads of other custom work.

The H-series need some tech love too!!

Random BS.. Syncro hubs/rings/gear selectors are the same (at least 3rd and 4th are) I have a B18c5 3rd-4th gear set in my prelude tranny. (not actual gears, but selector hub and syncros)

Huge Waste of money IMO..

 

I see...

What do you think about people putting zip ties on the shift cables?

Thanks

Slighly confused.. I'm assuming to keep them from moving much? I dunno, I've never had a problem with them and I've roadraced for years with mine.. 10-20 shifts per lap... I've never done it, but I assume keeping the cable lubed is the best thing to do..

for prelude guys Yes.

for hybrids No.

I have heard that the Twin Disk Clutches help allot on those high RPM shifts.

I had no issues shifting my stock M2F4 at 8800+

has anyone done a fully built H22 swap with the b-series tranny adapter plate using a ITR tranny yet?

How do "We" know this? from a bunch of hear say? I dont have any problems with shifting at high rpms. try 9,900 to be exact. It worked fine.

Maybe if people stop making excuses and actually spend some money and buy new synchros, and sliders, or maybe even a decent clutch. There wont be so much BS flying around..

People also have to realize that this is racing, if your smashing down a open street or on the track.."Speed shifting" tears up internals in practically any kind of tranny. So a rebuild after a few events of thrashing through your tranny will keep it shifting smooth.

 

so does any1 have any ideas to increase the strength of a daily driven trany?
2point6 said he replaced his with carbon syncros or sumthin but i duno .....

exactly.....my tranny came out of lookofsky's car....it shifts fine for me at 7500...it shifted fine for him way above that....m2f4 w/coated syncros, he ran a tilton clutch and never had shifting problems....

a real clutch like a tilton and gearspeed syncros will take care of the shifting "problems"....the only reason that is said is because of the idiots bashing it into gear before the slow *** single disk clutch has even released yet....stretching cables and ruining syncros....

like said above....coated syncros will do the trick...scott didnt need them anyways lugging that motor around like a diesel....lol randy....

 

 

the gearspeed rebuild seems like the most cost effective way but as for a tilton clutch.....? i'm not really interested in buying a $4000 clutch for my street car

 

Carbon synchros work well and I used to shift at almost 9K without issues, but I no longer need to shift that high.

We know this because it is true.. If you dont have problems shifting at high rpms then you are the exception rather than the rule. It is pretty well known for this. And it really can't be hearsay if many people have first hand experience.

 

The problem is that the synchros (which act as a brake for the gear) don't slow the gear down fast enough to allow the selector hub to engage without grinding and/or causing a miss-shift. The carbon braking surface on the synchros lasts longer than brass and actually helps slow the gear faster as well. Combine this with a good fluid such as GM Synchromesh (friction modified) and this will help the survivability of your trannys internals during those highRPM shifts. You could also look into a Houseman "dog engagement" gear set as well as a "slipper clutch".

 

mind defining a "slipper" clutch?

whats the site for the h22 with a b series tranny?
