That's a great job there Ryan, this is a serious diet, I like it :)

 

May I just publicly thank Ryan for his help with my Motec ecu install, which is something a bit outside my normal line of work. He has been very kind with free advice, and he's a credit to the club. I ordered some heat sealable splice, eyelet and spade connectors from RS today, it's amazing how connectors and stuff mount up, I can see where the huge bills for a Raychem loom came from that the previous owner of the red Zeus had made, when el cheapo stuff from RS mount up like this :(

 

 

 

Thanks Ryan, any help I can give you please just phone or e-mail.

 

No problem Chris. You have my number now if you get stuck

 

p.s let us know when you get the Ohlins :)

They're the Seibon ones Chris :(, I didn't realise there was going to be so little difference between OEM & what I was looking to buy. Even the glass, if its living with lexan windows or having the hassle free glass for approx 5kgs, I think I'll take the glass.

cool...was that impact bar bolted on or welded on when you removed it mate?

 

and are you going for a complete custom cage which like cost £3k from the specialists or are you going to go with the bolt in stuff then modify it to suit ;)

 

It was welded on at the ends and then the rest of it was attached with a tough rubber sealant.

 

I have a 6point chromoly cage which weighs about 11kg and then i will be getting it welded in and tagged to the chassis. Then we will be welding on the other bars for the doors etc.

'kin hell, is that all it weighes! I'd have guessed it be 3 or more times that. Your target weight for the car is looking more and more realistic :)

Todays work

 

The day started with getting the fuel tank removed and all the lines from under the car as alot of welding is about to start.

 

Myself and Steve then moved on to getting the diff out as this going to be replaced also.

 

After this the fun started and the air hack saw was brought out again to remove the bulkhead and some of the floor ready for the engine move. As the car is not on the Jig just yet we only removed the bits needed to ensure no main chassis strength was removed.

Sleigh anyone?

The floor and the bulk head came to 25kgs! Im sure the alu sheeting and T45 wont come anywhere near that.

 

After doing this i ended the day by removing the rear glass and the boot lid ready for weight reduction mods tomorrow.

Rear glass weighed 10kg

 

Also weighed the steering column which we will be replacing and this came to 15kg!

 

More to come tomorrow

Yes the engine is going to be moved back to help the weight distribution i would like in the supra.

How much further back are you going to move it Ryan?

Are you going to have a shortened custom driveshaft made for her from carbon?

Sounds interesting, can you expand on this a little more please Chris :cool:

 

I'm no CW, but it's a sound proposition (and an engineering nightmare in the supra chassis). Transaxle is pretty much a diff, gearbox, clutch and flywheel in a single unit mounted at the back of the car. It's the same sort of thing the vette's use (except I think the clutch/flywheel is mounted on then engine). There's huge benefits to weight distribution as the box weight is just infront of the diff instead of just behind the engine. I think there might be some drawback in drivetrain power losses, but it's an interesting idea, but one of which I highly doubt is worth the bother.

Brave, brave man! You might as well ditch the diff and fit a transaxle with the prop at engine RPM. It could even be a rearward weight bias then.

 

second hand 911 G50 porsche is quite a common one, cant get my head round it though if it would be the right way round, maybe have to run it upside down, hell of an idea though Chris

Loads of stock road car have this. New Skyline, Porsche 944. Porsche 928, ZO6 Corvette, several front engined Ferraris, et cetera.

 

Quite a few front engined race cars have improved the weight distribution by having a transaxle, either with the clutch on the engine (preferred) or on the transaxle itself. The race Prelued I put a link to in another thread has that arrangement. TVR built a front (Cossie Sierra turbo) engined car with a Hewland transaxle in the eighties.

Today i removed some weight from the rear hatch

 

The rear hatch without the glass weighs 16kg after removing the extra 2 skin layers we got it down to 6kg :) The rear hatch will be fixed to the car with 4 bonnet pins, the bonnet will be done the same way. When all the work is done we will be going back to all the cut bits and tidying them up ready for spraying.

Im hoping that when the lexan and pins are all fitted the hatch comes under 10kg. Before it weighed 26kg with the glass fitted.

 

Also removed all the wiring loom from the front as this will be replaced.

 

The car is ready now for fitting the engine back in and fabricating all the new mounts.

Back to work tomorrow at Autosport show but hoping i will be back on the car this saturday.

You are a busy bee, well done Ryan, a serious weight reducing programme indeed :)

 

Just to wander off topic, was speaking to someone called Geoff Page at the show, by phone, today, about a race car i am thinking of buying. he was singing the praises of the Life ECU's and saying how good they are. He uses them to modernise turbo F1 cars, and finds them better than Motec. I am slowly erring to giving one a try at some time ;) He was an extremely interesting guy, and someone I hope to meet soon. A link to some of the stuff in his workshop:

Not heard of Geoff but certainly looks like he has some awesome projects. Will look out for some of the cars tomorrow and maybe say Hi.

 

He is spot on about the Life racing/Solaris systems, they are leaps ahead of Motec and others now. Had to map a motec the other day which seriously got on my nerves after using the Life/Solaris software lots recently as its such a better setup for a mapper unlike the Motec software.

 

Plus you make a big change on the Motec and the thing pretty much crashes... My offer with the Solaris and your Zeus still stands. Im sure if you spoke nicely to Solaris they might lend you an ecu for a season also in return for abit of advertising ;)

 

When we setup my suspension i will show you the Solaris software in action and its features and im sure you will be swayed :)

Great pics Chris, one thing I notice, the endtanks on the intercoolers, don't they appear a little.... thin. People are always on about how the Greddy/HKS beat the competition on the Supra for example due to the endtank design?

 

it may well be a compromise packaging issue i suspect the car this came from didn't have a lot of room for luxurys
