Type 9 Box
I have a type 9 box in the car at the moment.
I have read that the max power for a type 9 is around 150bhp. The engine is producing around 190 and so far so good.
I'm thinking of geting around 230 bhp from a replacement engine.
Is anyone putting more than 160-170bhp through their type 9 and if so has there been any problems?
I will eventually look for a T5 but not sure if is will suit the bellhousing and my conversion plate.
Does the T5 fit the same bell housing as the type 9?
Thanks in advance.

Last first, no the T5 bellhousing wont fit unfortunately!
Next, difficult to say what will break a type 9 in a 7!
I broke several behind a 200hp, 168lbft vauxhall XE engine in my rwd pug 205, and several getrag 240 boxes (which seem similar in strength to the type
9) in my manta with the same spec engine in it.
That said, I have the same spec engine in front of another type 9 in my 7, and I know of two track dayers with westfields running 200hp VX engines who
have done 2 years of track days on scrapyard type 9's with no bother.
I think the 7's (relative) lack of traction and light weight limit the actual torque applied to the box.
In your position I would be tempted to keep the std type 9 and give it a go! They are £25 a time to replace from the scrappy at the mo, so buy a
couple of spares, its cheaper than a gearkit!!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I would only take that figure as a guide. As they are fairly cheap just try it till it complains. Otherwise get a box with at least uprated input
bearings.
The loadings in a kit car are very different from that intended on a Sierra. Diff type, tyres and driving technique will all influence your gear box
life.
Also I believe the type 9 fails just quickly from high RPM as it certainly wasn't designed for that. BGH boxes are modified to improve
lubrication as well as the stronger bearings.

could get Quaife innards, but thats expensive!
Defo put up with the extra grunt though.

Tough decision.
I was in a similar position and picked up my HD Quaife box on ebay.
I was going to go the BGH route but this was cheaper.
I didn't like the idea of being stuck out on the road / track with no transmission.
There's one on at the moment, tad pricey though.

Thanks
I was thinking along the same lines as the "suck it and see" position.
I was just checking to see if its a deff "NO"
I will monitor the situation and as its unlikly i will use the car on a track it may hold out.
Cheers

Got this drawing of a type 9 from somewhere a while back, probably off LB!
Seems Ford spec max input torque as 200Nm (147Lbft). Wonder if that can be trusted, and if that average or peak? Presumably a V8 with 200Nm puts
less load on the drivetrain than a 4-pot with the same??

well, I have a drawing but its not uploading - maybe I need to resize it or something. Oh well, everyone knows what a Type 9 looks like, hell I bet
everyone has a picture of one on thier bedroom wall, I know I do...!

Could you not use a XR4i gearbox? from a ford V6, cheaper than BGH or quaif and apparently can cope for up to 250.... if not then what are the
problems of using them?
