hi was just woundering what is the gaine off a strate cut gear box . is it strenth or gear changes .. i would like to know

 

power output...

stright cuts do not losse as much power as helical ones do!

alex

 

theres very little thrust loading on the gearbox so less losses,,, strength,,,,

 

GARETH T, so you gaine strength

 

Yep, as the helical ones try to push themselves apart = increased loadings. Helical is also much quieter, hence production use.

 

ADBR500 your spelling is terrible You will gain strength from a straight cut box. Your best bet it to speak to bernie at cts (gearbox man)

 

no you loose strength most of the time... Helical gears have 2 or more teeth in mesh at any one time where as st8 cut only has 1 tooth at a time... however don't confuse a quafe st8 cut kit as being weak, it won't be - the material the gears are made out of and the hardness of the gears will be MUCH better than std.

The advantage is helical gears create a side thrust as the turn... where as st8 cut do not.

alex

 

you normaly gain strength because normally they are bigger teeth,,,

 

tonyk, hahah i know will sort it out m8

 

GARETH T, thanks every one that all i need to know so how much

 

a str8 cut quaife jobbie for a rst power limit is rcomended at only 175bhp so they quote

whats that about then


what will it take

 

so is it worth having all gears straight cut or just 1,2 and 3?

 

if you use the car on the road,,,, dont have ANY straight cut

 

Im putting more than that through one and thats N/A Gus Had it over 10 years now with NO problems other than new gears every now and then just due to wear and tear.

Oh and they are bloody noisy

 

I like the noise gareth , loved Big Niges cossie, and Fletchs cossie sounds awsome.
wont be an everyday car anyway, only shows and southend and the odd trip to the pod and bedford

 

GARETH T, why not to have straight cut gearbox on a road car

 

what they quoted is what put me off getting it


well that and bernie said that standard rst gears are well suited, fords did there job there then

 

Benn 304R, they do sounds cool,,,, but you gotta be hardcore to drive one alot on the roads

abdr500, go for a long ride in one

 

Thats where a big sound system comes in

 

Take a look at the ratio's of a standard box against a straight cut one and you'll soon see 70mph at 4500 revs or something. Ideal for a track car though

 

You'll be lucky Benn.

The noise is fun in a novelty way, but you wait till you're driving for time - more whining than the missus

 

now i know that aint possible

 

well if it drowns out her whinging then im defo getting one, at leats its whinning for a good reason

Not sure exactly what im doing yet anyway, just checking out whats availble for the money i will have.

 

The noise is not fun after the first 5 miles or so believe me Benn.

Its not just a whine its a high pitched screech mine puts out. I can not even hold a conversation with the person sat next to me unless its through the intercom.

 

I understand what your saying, but wouldnt it be not so bad in mine as i have all the interior plus extra sound proofing on the floorpan anyway, that i put in awhile ago.

 

Put some inside the gearbox casing too then

 

now theres an idea

 

but they arnt three times the surface area of a helica set are they?

alex

 

i'll second that

"a str8 cut quaife jobbie for a rst power limit is rcomended at only 175bhp so they quote

quaife always under quote and wrongly quote there gearbox and diff ratings, for a start its not the horse power that will kill the box , its torque and revs , so the hp rating is just a number , mu dogbox has a rating of about 160hp iirc, and i run a little more than that with near 400ft/lb through a box that is over 25 years old

 

i cant do that in mine, and my box is std

 

id like to bet you a good wedge its nothing like

 

I actually fell asleep in Martin Hadland's Escort on the way to Germany - with stripped interior, and straight cut box, it makes a hell of a noise!

I fell asleep cos I was absolutely fooked, but I woke up with some fookin headache!

 

My normal Box sounds straight cut LOL....

Straight cut doesn't always mean its strong either....more down to the quality of materials and engineering involved.

 

"and Fletchs cossie sounds awsome"

Cheers Benn, come down Sutton BP one Wednesday night and I will take ya for a spin mate, so you can hear the straight cut from inside the car I did 3000miles in mine before I blew the first box up and everytime I drive it the straight cut dont bother me in the slightest... Normally turn the stereo up and listen to that
