Did some work on the car, its been a while since I really got stuck in with some cutting welding and painting. 

I decided to do a little more work on the roll hoop mounts.  So I removed the large box section bits you can see in this old photo.


And I've added tops with captive nuts, and a base for the roll cage man to weld straight to reducing the work he has to do and hopefully the cost a little too.  I'll do something similar for the base of the diagonal down bars too and the door bars. 




Now drying


More to come

[lozzzzzz]

All done and back in the car now.



I'm thinking of doing something similar with the diagonal down bars next and even some mounts for the door bars, maybe.

But now the fun is over, I've got to do some work

More to come

I've been trying to make another way of silencing the car a little more for the long boring journeys and this is what I came up with. 







Hopefully you can tell from the photos that these get pushed into the exhausts and mean the gas has to take a torturous route to get out.  Restrictive yes, but removable too   The hope was that the gas will have to go up the center of the first section of perforated tube, out through the walls to the surroundings then back into the perforated tube before coming out the back. 

Bit like this:


But guess what.....  it hasn't wo... well its the best thing yet but it still isn't killing the drone. 

[lozzzzzz]

Right then, this wire wool is really doing the trick .  I've no doubt its restricting the hell out of it, but it really has made it quiet

And its easily removed

Its not the neatest, but I now have a direction to head in making something better in the future. 

First I cut the ends off, so its a much shorted perforated tube now, and with one blocked end


Then cut up some perforated ends to stop the wire wool blowing out, I even drilled the holes out in an attempt to make is slightly less restrictive.



Then I went and bought the Co-op supply of scourer's (sp?) and filled up the tubes.


Drilled some holes and popped some rivnuts in and hey presto!



More to come.

wont those scourers melt and cause shrapnel to exit ---wire wool burns-only a guess though

We use to do a similar thing when we rallying. Fail noise test on scrutineering just bung it full of wool. Didn't make that much difference to performance but we running a 1.9 Pug with a 2.5 exhaust so probably had a bit spare capacity. In fact if you turned up with load of wire wool at scrutineering you could make a killing selling it. Nearly everybody needed some!!!!!!! Was a strange on our car. The colder the day the more likely we were to fail noise test. Oh and yes we use to finish the rally with less wire wool than we started. I used a very course wool so loss was minimal but the fine stuff was always flying all over the place.

[lozzzzzz]

Hmmm, i'll keep an eye on them, i used the course stuff in the hope it would last a while, if not i can open them up and put more in.

Hi folks something concerning has come to my attention. 

I didn't realise that the R28 box is Rear wheel drive and rated for 280Nm of torque until recently. 

I need to change my gearbox as its broken through a non-torque related issue.  However as my engine is producing 340Nm of torque I'm a little concern about how long it or the replacement will last.  I'm also considering supercharging the engine this time next year. 

It was my understanding that the R25-R28 has a bit of a reputation for being a tough one, is this right?

I've never actually read anything about a broken one?

I've got a feeling it'll be alright.  I've done drag racing starts on seriously sticky tarmac, so its not going to snap anything, I think it'll just be a case of accelerated wear.  If it was designed to do 150K miles with a 280Nm engine, then I can live with the idea of it doing half that mileage with mine or even a bit less. 

Do I

replace like of like and see what happens

Or

is there an R30 option which might stand a better chance?  Is it a like for like replacement, is it fitted to the 3.2???

Any info on this other box would be appreciated (if it exists).  I'm thinking of buying a 3.2 car for its engine when doing the supercharger conversion so it would be mighty convenient if a stronger gearbox came with it.

I don't believe there's a stronger option that is an easy swap. You'd have to go to a different type of box and probably modify the bell housing, etc. However, torque handling in a gearbox is more about what the back wheels can put down. In a small car like the Scimitar I'd say the box will be having an easier life than in an Omega, even with a bit more power. My vote's to keep the R28.

[lozzzzzz]

Thanks Kevin that was the sort of reply I was after

I've really started ripping into the electrics now, I've made all the changes to the central dash, and all of the bits that needed changing on the drivers side, and I'm in the midst of opening up the bulk of the loom on the passenger side now.  I'm basically giving everything that has anything to do with the ECU an earth on the "busbar".  And hopefully that'll cure the earth loop problems.  I've got a fairly good idea of the problem now, after much reading and sifting through various webpages. 

This is the busbar:


This is where its going:


And this is the mess as it stands at the moment:


Apart from the busbar, the other changes are to get rid of the Map switch and have it auto switch to Map2 when the LPG solenoids open, bin the fuel pump switches as they have to be on all the time anyway (even when on gas), and add an LPG momentary kill switch.  This will serve two purposes, firstly ont he very rare occasion the LPG plays up it'll mean I don't have to switch the engine off to reset the LPG ecu, and secondly (and more cool), it'll give a 20s go on petrol then switch back to gas, good for overtaking when lots of power is needed.

These arrived yesterday, so I'll get them fitted when I'm done with the wiring, then when I can find the time to go get the front springs the handling should stand a chance of being ok

I requested they make them 1" shorter this means I can raise the exhaust and hopefully have less exhaust road contact


Meanwhile, the wiring still looks like this


More to come

[lozzzzzz]

This won't pick up pace for about a year yet but the supercharged 3.2 project has officially begun.  I've bought a 3.2 engine (with forged crank) and conveniently an R30 gearbox  

Thing is its completely covered in car at the moment



With the exception of the engine and gearbox all other parts will be available if anyone wants them, Full memory leather interior, Irmscher body kit, SS cat back exhaust, 17" wheels, HID lights, Calibrated dash, Diff etc. 

I'll do a proper thread on the parts available when I start taking it to bits though. 

Anyway off the garage for more Scimitar wiring. 

More to come

Nice looking motor you got yourself there... 

[henryd]

That looks to good to break
