I Jet's Bf F6 Ute Build

[I JET]

I don't want this to turn into a big debate. I mentioned several times already that I've only got myself to blame. Its important for everybody to see how harsh the consequences are for speeding offences now days. It may just stick in your mind the next time you put the foot down... There's a time and a place for everything, I chose poorly and I'm paying the price.

This is my phobia.  

I drive for a living.  I'll get out of taxis soon (hopefully) but will probably still be involved in passenger transport in some way (buses).

If I get done then it's not just a matter of copping a 6 month suspension - Dept of Transport won't let me drive passenger vehicles again.

My FPV ute has done some high speed stuff on quiet suburban roads (late at night), but is kept slow on main roads.  I'm constantly looking for speed limit signs.

The consequences are ongoing...  try and get insurance once you disclose this one to any insurance company.  

A laser jammer will be required on the next car.  

I had two suspensions back in the 1990s for demerit points.  No big deal, but then I couldn't get motorbike insurance.   Lost two bikes to theft... uninsured.  Cost me a fortune.

Meanwhile, some moron can run a stop sign and kill a motorbike rider, and just get a small fine and a few demerit points.

As you say, it's all about time and place.  Both of these need to be carefully selected these days, and there are bugger-all moments of getting them both together.

Considering the consequences of this one, it's worth getting a good traffic lawyer on to it.  Someone who will investigate the case and ask the cops all the right questions.  Just in case something wasn't done to procedure (eg training not up to date).  A loophole is unlikely but go looking anyway. 

Condolences, and good luck with the court hearing.

I'd say the other way around is (only just) safer

small update guys... it has been a while.

 

1. Flywheel Issues.

Late last year I had my flywheel come loose a few months after the new clutch was installed. Sounds horrible, like a bottom end knock which goes away when clutch is depressed, I thought my box was lunched as the symptoms were similar to an input shaft bearing. After pulling the box out I was pretty relieved to find out it was the flywheel. After speaking with NPC I came to learn it's pretty common on these cars when running more than standard power. Its also the first & last time I do up flywheel bolts with a torque wrench to 'specifications'.

 

Rear side of flywheel had a few hot spots from rubbing back on forth on the crank. This face was skimmed back & the face of the crank was very lightly linished to remove any high spots.

 

 

 

There are a few different fixes for this issue but decided to go with one of the more engineered solutions. We drilled & dowel pinned the flywheel & crank shaft. Using a mag base drill, the flywheel machined and installed back on the motor with new bolts, we drilled 3 holes through the flywheel & into the crank shaft the total depth of the dowel pin. The dowel pins we used are solid diameter 10mm precision machined, heat treated din6325 standard with a m6 tolerance. We used an imperial drill size 25/64 which is 9.92mm. The dowel pins are 10.006mm - 10.015mm.

 

I'm told this was common practice on the high revving cosworth motors used for racing in the 70s & 80's.

 

 

 

 

 

 

 

Everything worked like a charm. We took our time & triple checked everything before drilling. The car has been going great, its been just over a year since this was done.

2. Leaky diff hat

Resealed with some fresh oil. Old oil still looked brand new after 10,000 kms.

3. Front brake pads.

These brembo pads have done 25,000 kms.

 

 

 

4. New Looks.

I decided to remove my oem hard lid & install an FG sports bar. For practicality reasons but I actually like how it looks.

 

 

 

 

 

5. Rear End Tramp!!

My ute has always suffered with bad tramping ever since the power increase. Rear shocks were due for replacement also.

I'd seen these solid diff mounts used on another forum & the guys really seemed to rave on about them. They claimed to dramatically reduce tramp or axle hop while also tightening up the rear end feel.

 

 

I had a local performance machine shop make up a set for me & I'm super happy with the results. Axle tramp is reduced to next to nothing -

With the stock or nolethane bushes I would rate the tramp a 10/10

With the solid bushes installed I would rate the tramp a 1 or 2/10 (its gone in almost all situations however I have experienced very light tramp on certain bits of tarmac in certain situations)

Other big win is the LSD works better, it feels tighter, handling is more predictable & corners flatter. When the back steps out under power its so controllable now.

 

 

 

 

 

 

 

The first iteration of the solid plates had some small fitment issues where the pin on the leaf locates & also the overall thickness was a few mm off. I had some further machining done & they now fit perfectly. You can see in the last pic how the top and bottom plates pull up hard with no gaps. Spot on now.

FYI : here's a photo of a the pedders saddle bushes installed. They squish & deform quite a lot. Oem rubber ones are worse yet again.

looks good, now upload a skid video

Good to here the dowels are working for you.

 

We had bolt torque issues. dowels couldnt hold on. The tensioning and loctite sequence has a big influence on whether the joint lasts.  

 

Since we repaired ours 5 years ago no issues touch wood.

Hi mate, I'm wanting to get some of those solid leaf spring saddle bushes you have. Did you give the machine shop and old bush or dimensions or what? Can you help me out?

Thanks!

[I JET]

Hi mate I can put you in touch with the machinist that made them. The original set was dimensioned from a new pedders saddle bush but then further machining was done after the first trial fitment to accomadate a better pull down on the U bolts and better clearance to the centre bolt / pin holding the leaf pack together. The machinist has all the final dimensions. When I spoke to him last he did say he would need to make at least two sets at a time to make it worth his while but he is really good to deal with I'm sure he will sort you out. Like anything, making one offs arnt cheap. If anyone else is interested in a set now would be a good time.
