thminiman Posted April 23, 2007 Share Posted April 23, 2007 sup cunts as some of you know, the thaughts of a straight cut box are going thru my head at the moment, but i sorta want to no all the goods and bads of them first, and what exactly you can and cant do with them, cos ive heard mixed stories. so, whats drivability like? any good around town or shit? what can and cant you do? when exactly do you need to clutch? choice, will prolly ask more questions http://www.minispares.com/Product.aspx?pid=35964 http://www.minispares.com/Product.aspx?pid=38071 http://jackknight.co.uk/onlineshop/prod ... cts_id=168 Quote Link to comment Share on other sites More sharing options...
EURON8 Posted April 23, 2007 Share Posted April 23, 2007 Just bang through the gears shifting up no clutch. No synchros. (could be wrong but ive heard) ya gotta double clucth on the way down Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted April 23, 2007 Share Posted April 23, 2007 Don't you just have to rev match down shifts rather than double clutch.. But if you know how to drive at all you'll be able to do that anyway Quote Link to comment Share on other sites More sharing options...

peteretep Posted April 23, 2007 Share Posted April 23, 2007 there will be no city drivability thats for sure Quote Link to comment Share on other sites More sharing options...
thminiman Posted April 23, 2007 Author Share Posted April 23, 2007 im just getting more confused now, there appear to be different type's ones with synchros, ones without... i know i'd loose some drivability around onw, but how bad is it? you must still be able to use clutch if you want. yes?

Mike-e Posted April 23, 2007 Share Posted April 23, 2007 sound alone = makes worth doing "zomg its supercharged" etc Quote Link to comment Share on other sites More sharing options...
Jase Posted April 23, 2007 Share Posted April 23, 2007 straight cut gears or "crash box" good fo serious track work and race applications but really pissing into the wind here,but you aint gona drive round town easily if youre worried about ure box breaking how about getting a gearset shotpeened relieves any stress points and leaves you with your driveability Quote Link to comment Share on other sites More sharing options...
sholdowa Posted April 23, 2007 Share Posted April 23, 2007 The only reason that the gears are normally cut on an angle is because they're quieter, but it also makes them weaker. There's absolutely no reason for a straight cut gearbox not to have synchro. Double declutching isn't that difficult, but it is slow - my mum still does it! For a mini, I thought the only box to have was a Jack Knight dog box - now that is noisy! Quote Link to comment Share on other sites More sharing options...

Gaz Posted April 23, 2007 Share Posted April 23, 2007 Whats the pricetag on one? Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted April 23, 2007 Share Posted April 23, 2007 I doubt its worth it, surely the standard box will handle the power. The sound may get a lot more annoying after a while. Quote Link to comment Share on other sites More sharing options...
thminiman Posted April 23, 2007 Author Share Posted April 23, 2007 ok, incase you guys hadnt noticed, this car is already likely not to be a town driver, its a 'fast road' car, ie, a road registered car that i can rape the shit out of, and know its not going to break. deal is, i dont do things by halves, i know i dont 'need' a straight cut box, but really, why the fuck not. only thing thats gonna stop me: cost am really just asking how much its worth it, ie, how fucked am i if i get caught in traffic.

thminiman Posted April 23, 2007 Author Share Posted April 23, 2007 kit i'd probably get is just under 400 pound = 1100 odd bucks the Real expensive ones are around 1800 pound (6g), 5speed, LSD, bullet proof etc i wouldnt touch that Quote Link to comment Share on other sites More sharing options...
Gaz Posted April 23, 2007 Share Posted April 23, 2007 ^^^ shit. Isnt that enough to turn you away? Thats stupid money for a box. I recon you should recon your standard box completly and fiddle with the gears if you want. Make them close ratio etc. Maybe you can even go straight cut somehow here?

Gaz Posted April 23, 2007 Share Posted April 23, 2007 In short, helical gears operate quieter than straight cut. Straight cut will 'whine' the faster they go but offer both A. More directional application of force allowing for less power loss. and B. Higher acceptable loads until failure. Basically making the transmission stronger and more efficient. However though, like noted before, car manufacturers don't use straight cut due to the imense noise the transmission will produce. To get an idea of a straight cut gear noise, many manual transmissions (especially the older ones) use straight cut gears for reverse only. Therefore, going in reverse produces a whine, but forward will not. Haha, use all reverse gears Quote Link to comment Share on other sites More sharing options...
