Where do you want to leave it, Sydney or Melbourne? Sydney I can't help out for long, the front yard has to be cleared for when we move out in Jan. In Melb you could leave it at my warehouse for a while if you needed. It's lock up, but no guarantees on security. If pieces go missing, I may be responsible, but I won't be held responsible :P

Not sure, Sydney would be best but im trying to store it for cheap longish term. I very much appreciate the offer, will most likely take you up on it, just need the car to be ok then ill get my name on the papers and go from there :down:

Either way ill be in touch about the bonnet and front bar as soon as i know (by Sunday night) :huh:

yeah Brad mid (to late) Dec would be perfect. We sealed the motor last night (old mate of yours, Mike did it for us). should be right to put it back in this weekend or next depending on when I have to work. what event do you have in mind?

Steve....if you need to use a trailer and can bring our stuff back I think we can sort something out :laugh:

Excellent. Oh yep Old mike and I go WAY back.... as im sure you probably would have heard about. Damn he can talk, and talk, and probably talk a little more.

Never ask him about his old N13 pulsar! I made that mistake last time he was here sealing up the combined touring car engines. Bloody hell!

Nicest guy you'd ever meet though and providing you fill him with coffee and biscuits his happy to come out anytime.

He actually lives two minutes from my place so also kinda handy.

Ill call you re the days im thinking about doing.

Also guys have you sourced your cage material for Marks other car??

Im buying all mine in this week and have secured a really good deal on the amount I need.

Ill be doing the entire cage in the better grade "chromoly" purely due to the weight and the fact its working out cheaper than buying Mild steel from the old supplier.

Im taking the car trailer to pick it all up over the weekend if you still need material you welcome to join in.

I bought the steel last week. Where did you manage to find the cheap stuff, and how cheap was it. The Chromoly that I bought was marginally cheaper than the equivalent mild steel, but it still was not cheap.

??

big sprocket = small top speed. small sprocket = big top speed. hence for a car sized track you'll be wanting a smaller sprocket not the biggest one you can find... :yucky:

you sure about that?

i'd have thought having a large rear sprocket would give me a higher top end??

Sorry tiger but BB and Benm are right.

My Radical runs a chain as well. I don't change my front sprocket (17 teeth) rears are as follows,,,Oran Park GP (48 teeth),,,Eastern Creek (46 teeth) and Wakefield (50 teeth).

Haha thanks guys, now that i do think about it you are right. i was thinking bikes but obviously not thinking right.

i wont be changing the engine gear, only the rear but i will try put the biggest engine gear i have on.

i will have to ask the go kart shop what they'd recommend.. but i cant see myself getting off the throttle at all with the current gearing

p.s. i think you need to add a commodore badge to that thing you posted :)

Mark I got enough material to build atleast 3 cages similar to yours (two of the one Im doing) all in the highest grade chromoly the supplier has for a 3rd of the normal cost.

We roughly added it up to well over 100m of tubing in each size.

I also got the MDS (material data sheet) with it.

bkes, carts, cars all the same. you've still got it backwards though. for car sized tracks you will need a smaller rear sprocket. not a bigger one. think about this. if you have a small gear driving large one the small one must rotate many times for the large one to complete 1 revolution, it's easily worked out and that is the final drive ratio. so in a GTR for instance the diff input will spin 4.1 imes just for the wheels to turn once. yes you wont change the engine drive, there is not normaly any need to. in karting you can get a wide enough range of ratios just by changing rear srpokets. I think you need to go back to school big buddy!!

Yeha i figured it out :P i was thinking bigger for some strange reason. but now i remember from my old mountian bike which i've not riden in about 50 years! haha

tho i think i'd need a bigger engine sprocket, then perhaps about 10-15teeth smaller rear one. its going to be a C^$t to start!

Way too much on my mind latley with all this starting a business shit going on.

Apologies in advance if I've missed it somewhere, but if you guys are going to build Moly cages won't you need an engineers certificate for CAMS? And don't they run to 3k plus these days?

no, just leave $50 inside your log book when you get scrutineered at events. :( much cheaper than get it certified. :banana:

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Starting again

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
