cheers lads

 

Got a ball park price Marco??

Plus have you got to go 3.9 or 4.4??

cheers

 

hmmmmmmm,

but whats a hy-vo chain ???

 

Very intresting,

i remember you telling me about this last year.

 

Intrested in this marco any ideas of cost

 

Who is the willing volunteer / test dummy I wonder....

Needs to be someone with the ability to break a Cosworth part at a thousand paces.....

The ability in fact to break two cars on one day maybe.....

Perhaps even the sheer skill and talent to wreck 2 4x4 boxes in 2 weeks.....

Or perhaps just someone stupid enough to try running 440bhp through standard 4wd transmission, while ragging the tits off it on track.....

The kind of numpty who finishes a Ł3k engine build the day before he sets off to the Nurburgring for some running in.....

Surely noone is that stupid / destructive?

Must be the ultimate test in that case....sounds like if it can be broken it will be broken.

Or maybe just maybe it will be up to the job, not cost Ł2k plus, and everyone will buy millions of them, making Marco a rich man...

I hope so

Si

 

Go for it Si......

You are the new timothy tester........

 

Under 2k would be good!!!

 

Don't quote me on that bit!!! It might be so good Marco could move them on at Ł4k a pop....

I actually don't know the price, but I'm sure knowing Marco it ain't gonna be mega bucks, it will be the right price....

 

But the problems have already been sorted years ago!!!!

Quaife, Doughty, DOME, R+D and recently now Fixit all make these gearkits. So what makes this different Marco?

Its got to be one of three things to be be anything new.

1. Cheap
2. Much faster changing
3. Indestructable

Is it any of these?

Hope so

 

Indestructable ?? Now that would be impressive

I'll have 2 thanks.

Pisstaking aside though it does sounds like it could be a good option for people not wanting to spend loads of money on the running gear as long as it gives the results.

 

you will be paying for a trade advert then

 

id be really interested to see how this goes aswell

i used to go through a box a month in my last one and i wil be back in a cosy again in a couple of month sand dont want to go throgh the same agro

 

sell me some cheap dad!
\


sound top mate

 

Si

yes it's to you and free of charge you will have the box tomorrow night mate

all i want you to do is bed it in first give it a few 100mile thats it



pete

i will mate ,if the box works no problem at all i will be come a trader on the boxes and diff i undesrtand where your coming from as you have paid full traders membership however atleat give me a chance to see if the box works please you never know you might need one at some point for one of your customers


porkie

it's just a big tooth gearbox it will be cheaper than quaife/fixit/r+d

it's just basically an uprated box and i'll do it as cheap as possible for Rs owners

how long have you know me i'm not going to big up something if it's not going to work thats why i what a test tube baby

at the end of the day i have bent over backwards to get this box made for the peeps that want an uprated box without paying over the odds

I know Si car is 440bhp so that would be a good start to see what happens


if it works it works if it doesn't then i have wasted my time



marco

 

porkie

1 cheap= ,yes it's cheaper
2,Much faster changing = wont know yet
3,Indestructable = not sure yet i want to find out at what bhp it goes pop @ so i can say it's rated at so much XXX bhp

i think a 440bhp/390ftlbs sould be a good test and if it can withstand that power i might put it in yours as see free off charge of course

Marco

 

Well done Marco

Dave.

 

Hi Sargent major

ill try me best

 

marco, whats a 'hy vo' chain ?

 

Good job Marco!!!


Oh, and get yer Hair cut!!!!!

 

hi mark

it's a heavy duty step off chain for the 4wd system that turns the front prop


the chain will be either lengthen or shorten depending on what step off ratio being used

 

Will this box be tested on hard lauches or just road/track?

 

Hi dan

to be honest it will be tested on track first

at the end of the day it's big tooth box , first gear and reverse gear will remain standard as in standard pattern only

first and reverse are made in better matrial and alot stronger than the standard gears

i would rather the box do the talking not myself , what else can i say about it....... only give it a chance to see what it's like atleast i having it tested what more can i do

Marco

 

Hi Marco,

Thanks very very muchly - I hope I can prove the efforts you have made.

No launches to start with, and no full boost until everyone's happy. No point dumping full power off the 1st traffic light Grand Prix only to come back on here and say it's crap.

I'll test it so we can find where the breaking point is! But would like to see it do some miles before that happens!

I've got a track day this weekend at Castle Combe - will that be the sort of running in you're after

I'll get the box in for Thurs eve road testing and report back my findings as and when they happen

Si

 

Marco, hope you hard work and time pays off.

would be a good achievment if all goes well.... and dependant on price then i could be adding myself to your list!


I think Si and his car are a good starting point for the testing, a healthy power figure to test its capabilitys and strengths.


its also good to know your looking at opening the options up with the different ratio's which will certainly suit myself as im currently on 3.9 step offs and 3.9 rear diff - both of which have broken at some point on the 400ish bhp i was running, let alone the hopefull 500 i should be seeing when its completed again by spring!


Keep the updates regular Marco/Si

 

Sounds cool Marco

 

Hi Si

no probs please bed it in thats all i ask i'm not botherd what you do after that

marco

 

keep us informed

 

no probs mate will do

 

Hi kelv

thanks mate i hope it works out toooooo

as for the price it will be as cheap as i can possible do it , i'm not in to make a killing or rip peeps off i just want a product to do what it says on the can if it works then sound, all i would have to do is put a rating on the box rated @ such and such bhp

If the box is good and can withstand 440 bhp /390 ftlbs test

i will be looking for another test tube baby with a 500+ 4wd car escort/seirra

or even a rally car with loads of low down torque

cheers Marco

 

i certainly dont mind offering mine as donner car when the time comes
would be happy to have the car where ever you need it for whtever you need it for on a testing side of things!!
thats if you'd feel comfortable with myself offering my hands/car etc.

i will be doing the odd track days here and there, similar to Si i guess.

Car wont be back on the road until feb/march next year depending on your time scales - and due to everything coming together perfectly with Mark Shead etc


Kelv

 

Hi kel

all i would have to do to the box is change the spep off gear to a 3.9 for your car as the one Si will have tonight has a normal 3.6


see how it goes in Si first it might just pop don't know yet

marco

 

if you have one box ready does that mean you have several gear sets available. if so might as well sell em now at discount just in case first test box doesn't hold up

 

Cossie's ready and waiting Mr Polo sir!

Gearbox is out... and Doug is on his way to you as we speak to collect the box (was on the M5 about 30 mins ago).

Shouldn't you be out meeting him somewhere?!!! Or was he heading direct to you?

"It might just pop".... we'll see!

I'm keen to give it a thorough testing - so if you need some abuse / launching / 1/4s etc done I'm there....

Can you drop me a PM with the bedding in process you want me to follow? Want to do things exactly by the book so to speak, to give it a fair chance.

Si

 

Sounds good Marco


im sure Si will 'test it' properly


Slightly off subject - are you still able to supply those rear beam mounts i had before?

 

kelv

I have got a new name for the box if it works because everyone takes the piss out of my hair i will call it the MULLIT BOX


sorry getting back on to the subject about the ream beam mounts

i haven't got any at the min but i can always get some more made up

and this time i will have the center bits i think you had the set without the centers sorry about that i'll trow you in an extra pair of centers

have you fitted them on the car ? if you have how did you find them they are not as bad as peeps think i think they work very well on my motor the beam feels like part of the car

 

let me know if the preliminary tests go ok, and you wnt another donor for phase 2 !!


loving the 'MULLIT BOX' --- total classic

 

Hi Mark

for phase2 yes i would be very greatfull for you to test it if everything goes well for Simon if not then it's back to the drawing board

Marco

 

no worries pal, i would have to fit my drop gears, as im on a 4.55:1 set just let me know how it goes pal.
