Marco, i did have the set with no centres but managed to get a set easily enough, just had to have the wholes thru the centre of the mounts opened up by a couple of thou but all easily overcome!
theyve been brilliant, wasnt quite sure what to expect at first, have made the back of the car feel alot more fixed on track.
my only issue was when i smashed my rear diff, obviously with the beam being basically solid mounted it wasa herendous noise limping it home - thought someone was in the back of the car smashing a metal dustbin lid with a hammer!
only reason i ask is a friend was enquiring about them, but ill see if hes serious before i ask about them again.
Cheers

I have only one box built but have got 2 complete kits ready to be built
![Top](https://passionford.com/forum/images/smilies/smile011.gif)
there wouldn't be any point in building the others if it doesn't last in Simons car simple as that realy
![Sad](https://passionford.com/forum/images/smilies/icon_sad.gif)
i want Simon to be honest either way if it's good or bad, i 'm ready for the worse to be honest
![Surprised](https://passionford.com/forum/images/smilies/bigcry.gif)
if it breaks i would feel a bit bad because i know the hastle of fitting 4wd boxes they do take a long time to fit

when you broke the rear diff you would have heard loud noises and vibration really bad as metal doesn't move rubbers do
as for noise with them i found then no worse than poly bushes

please explain Tim?

and I will have had to go a long way to beat Markk's 'you won't EVER sell that FFD box on Passionford'![Surprised](https://passionford.com/forum/images/smilies/bigcry.gif)
P.S Tim, after you have finished 'trying' to explain what I have said is sooo wrong.... You may want to try and explain the little inconsistencies that Inspector Doug has found...

And they are all being used ON THE ROAD by people very successfully!!!!
well I don't know alot about the R+D kit but the rest are. They are TOTALLY fine for 440bhp cars on the road!!!!!!!!
I really can't see what I have said that is sooo monumentally wrong?!?!?!

Hi lads
Just to let you know , I have spoke to Simon who is testing the mullit box
he has just told me that the box has died
he said it was the box was fantastic in the first session and no probs what so ever
in the second session on the second lap he lost all drive
I personly think the layshaft has broke
which i know is the weakest part in any striaght cut box basically the shaft is standard part in pattern only
the gears are fine and the box hasn't exploded so i would say the layshalf has broke at the front where it goes to the VC hence no drive
Im a bit sad to be honest
I won't know for a 100% untill the box is striped down and looked at.
I am kind of happy in away that it's not the gears as the gears are very strong
all i can do now is try to sort something out with the layshalf
i'll keep testing it untill it's a proven product i wont give in
at the end of the day things dont go right first time around but i'm sure i will get there in the end.
all i want form Simon it to be totaly honest about the box
if the development starts to get too expensive ill just scrap the idea but hopefully it wont come to that
thanks everyone for your susport

thanks lads
it will get there in the end it's just cost
but like i said if it's going to be too expensive i will scrap it and i can say is that i have tryed
i know theres a market for a good fast road/track box " i aslo know that the price has too be right also " and thats what i'm trying to do
I can get layshatfs re made even stronger but if it's going to cost a fortune then it's not worth all the agro
it's catch 22 .... i could get another layshafts made in better matrial alot better to this one (which i will have to).. it would be the same again will it work ?
the layshalft is made from a billit and then machined to suit
and if the cost is too expensive you might aswell get another uprated box that is allready on the market
i know i would have to compete , if the box proves itself then i have a product but at what cost
i think of something when i get the box back of simon
on a lighter note it's good job i never sold it to Simon he would be looking for a refund

Keep your chin up Marco
At least you have had a go, and if you stick at it, hopefully you'll get there in the end!
I went out with Si last night to put a few more miles on the box.... shame its let go, but 1st attempts rarely work i suspect!

Hi lee
I have backing from 2 very good people in the trade to get the box working I only have to pay a bit towards the devolpment
yes all the gears are striaght cut big tooth gears but they arn't that noisey compaird to some other striaght cut boxes
I was thinking of getting a similar box done with helical big tooth gears
for 100% road cars that might happen if this box works out

the layshaft in this mullit box is the same in parten only,
it's machined from a billit basically and exact copy but in stronger matrial
if i was to use a standard layshaft the box wouldn't last 2 mins on a track

Marco: i have an fixit on my car, and a few of my friends in sweeden also use theese boxes, without the layshaft problem, but they dont use this on the track as much as you guys do, do they brake because of the downshifting into corners aso?
Cause the fixit is rated to 600+++brake, and this uses the standard layshaft?

track days are very hard on any uprated box and using an uprated box on the road isn't going to get the same comparison as you would get thrashing it on a track and would have even more stress on a rally car
i don't know how they break i think just down to 4wd load on the layshalf

Gutted is not the word......
Just thought I should post up my findings so far -as Marco has said I have managed to break the Mullet / Mullit (how do ya spell it?) box already
Having spoken to Marco on many occasions in the last few days I'm starting to get an idea of how much thought and money he has put into this new box - so I'm gutted for him.
HOWEVER WE WILL BE BACK
I'm going to do my best to get the box out tomorrow or Monday, and take it to Marco for his inspection - We need to find out what I have done to it - then whatever is wrong will be resolved and retested.
It could be my driving (I have no mechanical sympathy
), it could be my car (a problem with the front diff / prop affecting the box) or it could be that something in the box may need upgrading / modifying.
Whatever it is, we will correct it and we will be back to more testing.
I personally WANT this box in my car, and am prepared to do whatever needs to be done to get this box working 100%. For my own benefit and for Marco to see a return on all his work. He deserves it
So anyway, here's some pics of me yet again on ANOTHER tow truck
![](https://img.photobucket.com/albums/v11/SiB666/TowtruckatEurofest.jpg)
![](https://img.photobucket.com/albums/v11/SiB666/CosatEurofest.jpg)
And a pic through the reverse gear switch hole on the MT75 boxes - first my original box with SMALL TOOTH HELICAL gears
![](https://img.photobucket.com/albums/v11/SiB666/DSCF0011.jpg)
And Marco's Mullet / Mullit box with STRAIGHT CUT BIG TEETH. Think the differences visually are obvious!
![](https://img.photobucket.com/albums/v11/SiB666/DSCF0006.jpg)
On the road the box sounds AWESOME. It is NOT as loud as some of the cars I've heard running these type of boxes. BUT you can hear it and I think it's excellent. Sounds a little like reverse gear, but going forwards!!! But in a good way. 4th gear is SILENT, as it's a direct drive thingy (Marco can explain why properly!!!) In 5th at Motorway speeds it is NOT intrusive at all - you can hear it, but it's not bad. My exhaust which is 99dbs at 4.5k rpm is louder - so it is not going to be a problem for me on the road.
The sound just adds to the experiece - like the flames I get on the overrun, like the pops from the exhaust, the chatter noise and the induction whoosh - it's another thing that had put a HUGE smile on my face everytime I drive my car.
I'll keep you all posted on progress, I'm determined to help Marco to succeed - if only to see the Mullet / Mullit project become a household name
The Mullet box is dead, LONG LIVE THE MULLET BOX

sorry to hear the box let go, but like others said rome wasnt build in one day!
Gears look mighty fine!
and not that much noise would make it easier to sell them as well the price range

I would classify the new Fixit version as indestructable, atleast its running in several high powered cars and ive never heard of one that let go. 750+ bhp doing quarter mile runs ie mad launches. Its the the diffs that brake up instead.
