Ryan.G Posted January 6, 2009 Author Share Posted January 6, 2009 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 Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 6, 2009 Author Share Posted January 6, 2009 You mentioned about cutting out the floor, does that mean you still plan on moving the driving position and engine back in the chassis? Oh yes Quote Link to comment Share on other sites More sharing options...
jevansio Posted January 6, 2009 Share Posted January 6, 2009 Are they vacced pre preg, or wetlay up, does it say? Are they fully finished internally, like these? : http://www.gatesgarth.com/toys/DSC03236.JPG 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. Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 6, 2009 Author Share Posted January 6, 2009 thats a great job on the door ryan, what are you going to do to replace the safety aspect of that door, i.e the side impact bar. A side bar will be incorporated into the cage. Quote Link to comment Share on other sites More sharing options...
Milton79 Posted January 6, 2009 Share Posted January 6, 2009 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 Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...

Your target weight for the car is looking more and more realistic Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 7, 2009 Author Share Posted January 7, 2009 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 Ryan Quote Link to comment Share on other sites More sharing options...
Guigsy Posted January 7, 2009 Share Posted January 7, 2009 i guess your moving it back to get the weight distribution correct? Or are you doing something mental like putting it in the back seat Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 7, 2009 Author Share Posted January 7, 2009 i guess your moving it back to get the weight distribution correct? Or are you doing something mental like putting it in the back seat Yes the engine is going to be moved back to help the weight distribution i would like in the supra.

Rich Posted January 7, 2009 Share Posted January 7, 2009 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? Quote Link to comment Share on other sites More sharing options...
michel lane Posted January 7, 2009 Share Posted January 7, 2009 Yes the engine is going to be moved back to help the weight distribution i would like in the supra. cant you just put loads of fiberglass to weight it down in the rear..thats my excuse , i have 50/50 but weights 2300lbs....lol Quote Link to comment Share on other sites More sharing options...
michel lane Posted January 7, 2009 Share Posted January 7, 2009 oops sorry 2300kg Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 7, 2009 Author Share Posted January 7, 2009 (edited) 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? All depends on fitment issues of the sump but hopefully about a ft The stock prop will just be modified.

Chris Wilson Posted January 7, 2009 Share Posted January 7, 2009 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. Quote Link to comment Share on other sites More sharing options...

Homer Posted January 8, 2009 Share Posted January 8, 2009 Sounds interesting, can you expand on this a little more please Chris 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.

Chris Wilson Posted January 8, 2009 Share Posted January 8, 2009 Sounds interesting, can you expand on this a little more please 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.

Ryan.G Posted January 8, 2009 Author Share Posted January 8, 2009 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.

Chris Wilson Posted January 8, 2009 Share Posted January 8, 2009 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.

jevansio Posted January 8, 2009 Share Posted January 8, 2009 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? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 8, 2009 Share Posted January 8, 2009 They do actually, maybe there's a reason for it, hard to tell from that photo. I'll ask him if I see him Don't forget we are talking 80's technology here though! Quote Link to comment Share on other sites More sharing options...

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 Ryan Quote Link to comment Share on other sites More sharing options...
