PinkRinse quick question while we've got your attention on this thread please!?
The diff gives you more BHP right? because it pushes the power down to the wheels!? So in conclusion that should improve the BHP and give you a more accurate BHP number at the wheels on a rolling road surely!?



Diff alone does not give you more bhp , , it gives you more usable power (eg you can use the power insted of lossing it just spining a wheel)

it might affect the transmision loss ever so slightly , but i cant see how it would give you a more accurate bhp at the wheels? that just dont sound right at all , its nothing to do with accuracy , its just transmision loss , you will always get it .. .

No BHP increase, the diff is after the gearbox which is after the engine.

You just get more traction.

You know if you pull of a bit too sharpish and the (normally) inside front whell spins?

Well with a torque Biasing diff it senses the loss of traction (by noting that the RH wheel is rotating slower than the LH wheel) and operates internal clutches that shift the torque to the other (slower wheel) and will keep shifting it back and forth or using both until both wheel speeds match.

Hope I haven't taught you to suck eggs.

Ahhhh that's it! Cheers!
So it's best with a SC'd to make it stick to the road better then?
Hopefully it does work well with a N/A car...?
Sorry for all the questions. Just debating on getting one...

Works perfectly with an NA car (like mine) it even works perfectly with an unmodded (power wise) car. Its all about better traction .. putting down the power thats there in a more efficient way (when its dry lol). Course if you have a mega super modded car then its a good idea to get one because you've gone that far in upping the power you might as well get better traction too!

Great points! I will take one!

Guys,

The diff does not work by sensing a loss of traction, the clue is in the name. It is a torque biasing diff, it senses the amount of torque being applied to the driving wheels and bias's this across the driving wheels.

In a true sense it is not a LSD, as if the inside wheel is lifted from the ground it will not be driven as the diff will not remain locked. Also the diff will only work on throttle. It will not lock on lift off. This makes it more driveable on the road.

The issue with my gearbox has been resolved.. It was the input shaft seal. This can get nicked when the gearbox is refitted.. heh ho.. so if you get a leak, now you know why.

As the car was in, i got a set of 200bhp Cosworth cams fitted at the same time. So hopefully i will get a couple more bhp now as well..

Cheers,

Rich.

Quick update from me..

Been talking with Dan from DRM.. Basically I have decided not to go down the supercharger route, I am going to go for throttle bodies.. There are a number of reasons for this but the top one is drivability. Dan has been doing alot of work with the SCT guys..

These are the guys from the US who built the advantage III software to flash the dreamscience boxes.

I would say that Dan and Kevin at DRM have the most knowledge on this platform now, they are the only people who have to got to the bottom of how the manufacture's stratergies are implemented on the ford oem ecu.

Basically as we all the know, the standard ecu, will keep trying to adjust fueling, ingnition, compensation tables and more.. This is causing alot of the high profile tuners, lots of issues.. DTC lights coming on, cars running lean/rich/rough/revs hanging and more..

So, onto the throttle bodies. These retain the standard fly by wire throttle, they idle nice and they make power..

With the cosworth cams and the throttle bodies I am expecting around 215bhp.

Me and Dan are going to progress this kit upto around 235bhp - 240bhp on the standard motor with the addition of a CNC machined gas flowed head from ric wood. This is the max you are going to get safely on standard internals, I will be replacing rob bolts as well, so I can up the rev limit to 7750rpm.

Next year, I am going to build a full on all steel engine with a 9500rpm rev limit.

With a change of cams and increase in compression we should see 290bhp.. This will be plenty and will make a great trackday package, which is what i want to do. It will also be bomb proof and reliable.

Wish me luck..

Rich.

Sounds like a good plan. This why I went Mountune, hear so many stories of cars tuned with remaps/DS etc and then along comes all the minor niggles as you say, engine lights/revs hanging on or off/rich lean running a favourite for sure, think this is because tuners can't get full access to ford's ECU of which as you say does a little bit of self populating.
Am sure there are plenty of well tuned cars some ok and others after much to-ing and fro-wing back to the tuners, for me I just want total reliability, I might not have big power but it works and works 100% and where I can use it.
Few on t'other forum experimenting with throttle bodies (Jenvey make one -youv'e probably read that thread).
This will an interesting build, looking forward to hearing progress on this.

Came across this little article about mountune 185, just thought people might be interested unless everyone has already seen it?

Car is now in and having the throttle bodies fitted this week.

I will post up a graph and some pics when i get it back.

cheers,

rich.

Amazing ...I was thinking that but I already have the cossie inlet manifold doh! lol!

Keep it up!
