Anybody know the reason why bisimoto's f22 uses an adapter plate to run a d series tranny? I checked and the ZC trans gear ratios are almost identical to a 92-96 prelude VTEC tranny? Is he using custom close ratio gears? Anybody know if there are custom d series gears made?

 

shift linkage maybe?

also, how about the weight of the 2 tranny's? is that comparable? also the cost?

 

from what i read in his post, they take the abuse alot better than b and h series trannies.

bisi breaks alot of trannies

 

They take abuse better? Can that be possible? You would figure the B series would take more abuse because of having more power, they would engineer them stronger. Anybody else know?

 

'Bisi uses the D-series trans because Nemo originally had a d-series engine. Along the way all the fabrication and parts to make the axles stronger were figured out. Rather than starting a new R&D program with another transmission, he chose to stick with the design that already fit the car.

When he changed to the new car, he built it around the drivetrain that he had already figured out.

As far a gears and gear ratios, that would not be for me to divulge. Maybe he will chime in on what he is running for gears/ ratios.

Well, not speaking for him, but speaking for free information on the internet, are there any companies, like Quaife, that make different gears for the D series transmissions?

I know Quaife has them for the b16, and ATS has them for the b18, BUT havn't found out any info about d series. I've found places that offered to make a set of totally custom gears, but they wanted like $7,000 for them.

 

As far as I know Bisi's trannies are still built in Canada at Houseman.

I'm sure he just uses the gears that keep him in his powerband. It seems like there are just too many variables tires, weght, torque, rpm that knowing Bisi's ratios wouldn't help anyone anyway.

 

Knowing where bisi got his gears from would help though. And if racegearbox.com is it, then that's awesome. Anybody else?

 

i remember watching this video where he gives an interview. he mentions that he only has a 100 dollar upgrade to the tranny...i don't know if he was just exaggerating but i've been confused trying to figure out what he was talking about

Houseman in Canada.... Tranny Guru.

those were probably backup trannies just incase something happened.

If you read Bisi's post https://honda-tech.com/zerothread?id=1208706 he actually mentions Tranny improvements by Houseman.

D-series trannys are plenty strong. I made right at 500 tq. and once I got my clutch sorted out, didn't break a transmission gear the last two years I raced. I admit though, I saw quite a bit of case flex, but it didn't seem to cause any problems, just some weird wear patterns on the gears.

The real benefits to a d-series transmission is that everything is smaller. The gears are narrower, the bearings smaller, the rotational mass of a d-series transmission is far less than a B-series. It is an ideal all-motor tranny, the problem is that nobody has done the research on this except Bisi.......everyone just throws d-series transmissions away.......

Well, if ones pockets or sponsors pockets are deep enough, you can keep sending your broken tranny's to a tranny shop, till they develop bulletproof stuff. I'm really just wondering if there is a company out there that's developed new gears and other parts for these transmissions to hold up. And as i'm finding out from this post, it looks like houseman is the ticket, but they're probably not the only company. I'm just interested in finding one that isn't ultra expensive.

I know that high end drag racing is a checkbook sport, but its always nice to find something for less money. ATS makes gears, so does Quaife, (for b series), BUT, ATS is about 1/3 the cost of Quaife. Might be a company out there that can make custom gears for for d series for $1300, like ATS. Or maybe it will be $5,000 like i've also heard.

custom = one set or maybe 2/3 = much more expensive than ATS making hundreds of sets.

 

Definately, BUT I can see that if somebody else had the stuff custom made by a company, and they charged him a LOT of money to R&D it for him, they probably charged all the R&D time and money to the first guy, thinking that they would only sell 1 set, and that's it. But once the R&D is done it might only cost them $1000-$2000 to make another set of their already thought out engineered parts.

Case in point,
If Bisimoto paid mega doolers for Houseman to make a stronger tranny, the R&D money might already be covered, and each extra set that Houseman pumps out will cost them less than before. In economic terms, the fixed costs of developing the kit for the first time is very high, but for each kit after that, the marginal cost to produce one more kit is FAR less.

ahaha....good one

also srr makes final drives for hydro d-series trannies...i don't know about gears, i'm sure there are some companies out there for all the road racing d-series guys

 

Greetings all,
I use a D-series transmission because of its strength and simplicity for my setup. The gears teeth are short and stubby, lending significantly to its ability to withstand abuse.

For over a decade, I have used stock d-series trannys: 1 with a houseman final drive (7 years old), and my spare with a factory 4.25 final. We ran what seemed like forever with that setup, and even secured a 2003 IDRC championship with such drivetrain.

All was well under the 322 whp range, but past aproximately 330whp, I experienced 2nd gear synchro failure...a problem that plagued me in 2004.

This season, I have elected the assistance of http://www.racegearbox.com for a full transmission build. As a side note, my peer drag racers (big secret) have used liberty, houseman, hollinger, and quaife (just to name a few) to solve their transmission woes, much sooner than 290whp. You will not beleive how many people run dog type/striaght cut gears. That fact continued to solidify my faith in d-based transmissions.

I hope that helps.

 

by his own admission bisi is cheap ("frugal" he calls it ). it makes sense to stick with his d series trans after all the upgrades hes invested in it all these years. in the end not only did it work he didnt have to waste anymore time and money R&Ding a new setup. ::raises guinness:: BRILLIANT!!!

im not 100% sure but check with Gear-Speed. they may have access to different zc gears.

never have problems with input shaft bearings going out?

Thank you very much for chiming in. Also i would like to add if you read this, nice looking Insight. That baby is gunna fly. Good luck with the coming season.

Well looks like I should be contacting some of these companies and finding out how big of a dent in my pocket it will be. Can you guesstimate how much time you cut from your 1/4 mile by switching to custom close ratio dog box?
