Not free Ben but I got mine from office works for $145.00 I think. The best thing with the latest turbocad is it is compatible with autocad which cost thousands & you have to repay each year.
Turbocad will support DWG & DXF format which is what most machine shops use for their CNC machines. So you can simply draw it up at home & email to a machinist to get the bits cut out. I'm drawing up inlet flanges ATM for 1uz & 2jzge heads. Your drawings look great, you should see if they can be converted to DWG?

I have sent the mould (top pic) to a machinist. He wanted it in a step file, or IGS. He is going to machine it for me on his CNC. The 3d printer guy wanted it in STL. None of the file types mean anything to me, but I have been able to export in all of them so far.
I have just finished downloading Sketchup make, the old google sketchup. It is rated very highly, and supposed to be easy to use.
I will have a play and see how that goes, but$145 is about what I would pay to play.
Just not this week, because I just spent a fortune on 2mm Lantor Soric to use in the carbon doors when he shoulder is better. This will act as the infusion medium and make stiffer lighter doors than 100% pure carbon fibre. The laminates should wet out faster and more complete too, meaning nicer parts.
Don't worry Aaron and Andrew, I bought enough to do a couple of sets of doors.

Thanks Clayton, I have plenty of video from the incar. I haven't bothered cutting and uploading as I didn't think anyone would be interested.
I mainly use it to see what I was doing in the car in comparison to the data. And In case I get involved in the 'big one' I want to catch it on camera.

Here you go Clayton. A video of the rest of the lap and then some. I got fed up trying to get the racechrono data/virtual dash to layer over video footage using various video editors, so I purchased the Trackvision software that works with the Haltech IQ3 data logger.
This video is a comparison between the car before and after I did the corner and cross weight balance. It graphically demonstrates the benefit of having your cross weights sorted. (wedge as the yanks call it) The tyres had done another 50 laps between the first and second videos, so on good tyres it should be better still.
You will also notice the 1:07 lap itself had various driver issues, especially the wheel hop going into turn 10(final turn) when I forgot to heel-toe on the downshift.

That's a pretty impressive lap, this car is looking really fast & your nearly hitting 200 down the straight. The Haltech setup is super cool. That's the best way to watch a lap. Have you not wired the tacho in to the dash yet?
Have you compared any lap times to yours of cars at a similar power & weight, say 300kw & 1400kg? It would be interesting to know what the fastest Supra has done around Wakefield.
Your car is looking like a very real race car. It looks like the R154's gearing is limiting your power band of your engine a lot. I know it's not cheap but have you priced up some straight gears from PPG?
Are you having to ease onto the throttle out of corners due to wheel spin or are you flat with some lag?
LOVE the in car stuff! Need tacho
Great driving buy the way, it's sliding every which way before the balancing.

I have the tacho working on the racepack. I use the channel "EFI RPM" from the Haltech data stream. It does not seem to transfer across to the virtual dash, even when I select that channel to display. The Trackvision is a third party software provider, who I think worked with Racepak for the development. Haltech is a customer of Racepak I guess, and not as well catered for.
Reading the Haltech forums and manuals yesterday, it seems ther is an output for a tacho signal. I am going to have to investigate this as I think that is what the Trackvision software reads for the tacho display on the virtual dash. I now also believe that the Racepak dash and data logger need this tach signal to run the gear number display and rev limit/shift lights that I have never managed to get working.
I am easing onto the throttle, especially coming out of the final turn and the fish hook. I am actually using 3rd gear for a lot of the corners I used to use 2nd because the engine has enough torque to pull from lower in 3rd without the wheelspin I was getting in second. Less shifts and wheel spin has made the laps cleaner and a bit quicker.
I usually get on Natsoft (race results) when I know there has been a timed track day at Wakefield for a sticky beak. Last weekend I would have been in the top 5 with a pair of skylines etc. Looking on Natsoft is also good to check on big noters. I have found a couple of guys spruiking times some 15 seconds a lap faster than the official records show. I'll look up the times and see if I can search 'supra'.

Going back a couple of years, the best I could find was Shane Standley (Gorilla Supra) who did a 1:07.59. Here is a table with some of the best I could find, with Andrew and Damiens Soarer's to add relevance because we are familiar with them. These are cut straight from Natsoft (hence the spelling of my name). I completely understand that there may be faster times as not all sessions or track days get officially timed.

Don't be too concerned Andrew, I had to look quite a few years back to find some fast Supras to put in the list. Given it was supposed to be a fast Supra list, and there are 3 Soarers in the top 5, I don't think we are doing too bad. There are a LOT of supras in the high teens, and a lot more in the 1:20 plus range.
I honestly believe if I developed a JZA80 Supra exactly the way I developed the Soarer, then the Supra would be considerably faster. It has a lower starting weight, a more slippery shape, a bigger engine and beefier driveline (twin turbo 6speed configuration) and loads more aftermarket support.
It seems a lot of the Supra guys just want to drag race them.
Any rate, you are the fastest naturally aspirated JZ platform by far, unless that Pro Motorsport Sports sedan is NA?

So you don't want to hear that the data logger has my optimal lap time as a low 1:06 then?

Glenn Pro's Supra runs a 4l Ford in-line 6, turbo charged. It is de-stroked to 3.5l.
Delete his arse then. I am only interested in 'modified' Soarers, Supras, and other JZ platforms. Not complete engine swaps outside the Toyota family, that's cheating.

That's only theoretical, so it doesn't count buddy. Actual lap times only. Not our fault you can't string one complete lap together...

I concur. Only just noticed he was in your table. Trained observer. That car used to go better with the 6l Chev in it, I think. Birol Cetin or Bob Welsh would have results in it prior to Glenn possibly. I know, not Toyota, but worth your time anyway, for comparison.
I wanted to buy that car and put a worked 1UZ in it. Went and had a look at it, but there was too much work to do to it as most of the car had been stripped and used on other cars (for example it used to run Penske dampers and uprights from the Indy cars from memory).

I had a quick chat to Glen at Eastern creek event the other day, & had a look around the Ma70 supra. It looks a little rough but the chassis looks like it has major potential,(not a production car anymore, full out tube frame sports sedan monster), but the engine was running really rough & was pretty slow in the final race. He had to retire for some reason. I guess you were there somewhere Andrew?
I hope you two respect how fast your cars already are! That Gorilla Supra had 364rwkw's and full ikeya suspension, big brakes etc. I'm not completely convinced a Jza80 chassis is better, as I own one for my daily now. It's a none turbo & yes it feels lighter with very light steering & massive rigid door sills on it but it has MAJOR oversteer. The Soarer seems way more predictable & won't bite in at the rear so much. I think you two will be running very similar times after Andrew's gearbox conversion is done.

The car that is very surprising here is Damien Smith. The car had no cage from memory, goodness knows how he stayed in the seat. It was only running at 270rwkw & the t56 doesn't change to quick. The car had buddy club coilovers & a cusco diff I think, not really too modified & no weight reduction but very quick times. I think I remember on his site that he ran a 106.*** at some stage??? Hopefully for my sake it was something to do with torque levels.

277rwkw's on 10psi I think. I tried to look up the old v8soarer site this morning & it's been changed to a photo page of the car. There is a fat cage in it & it has a carbon front splitter now. I didn't remember it like that but I could be wrong. Maybe it was a pretty serious build. The Adaptronic site had some details on the car aswell & their is no info saying he did a 1:06, so the time sheet you posted must have been his fastest time.

If he only had 277rwkw, then his mid corner speeds must have been phenomenal. Although, 4L motor, 2 turbos and 10PSI...he probably had awesome torque which is more important than outright power.
Any way...I have been sitting around a LOT these last few weeks. One of the things not hampered by a bung shoulder is my ability to stalk ebay. This has lead me to find things I desperately need, but just did not know, or had forgot about. I have just become the proud new owner of a Moroso 3 quart oil accumulator (Accusump). I got it for $223 delivered, so cheaper than the oil hose I had repaired a few months ago here in Canberra.
Guess I better figure out where I am going to mount this now. I don't want it up the front of the car for weight distribution reasons. Behind the passenger seat would be ideal, but I believe this will fall foul of CAMS regs regarding hot fluids in the cabin. (I will read the manual - but my gut says not without some flameproof shielding)
The other option is against the boot fire wall where the stock fuel tank used to sit. This will mean longer lines. Apart from the cost of the hose I cant see an issue. (The -10 hose is relatively cheap compared to the fittings on each end so the length is not a major expense.) Given it works on a pressure differential, and fluids do not compress it really should not matter how long the oil lines are? I have seen a lot of race cars with oil/air separator tanks in the boot.
Thursday, November 06, 2014 - 04:52 pm, by: Clayton Carlyle(Clayton)
Ben I think it does matter how long the hoses are to a cooler but the accusump is a pressurized gas cylinder that acts as an external oil pump isn't it? Very smart idea and definitely easier than fitting a dry sump. It's probably better off in the boot because it will give you more oil volume maybe? Can you please post some pics when it's in? It only needs one hose run through doesn't it?

You are basically correct Clayton. The cylinder has a small pre-charge (10PSI) so it never becomes hydraulically locked. When your oil pump is working fine, oil pressure fills the reservoir with the same pressure as the rest of the oil system. As soon as oil pressure drops, such as during oil surge, oil is fed from the reservoir back into the oil system at the stored pressure.
So at the worst case I have 2.8L of extra oil capacity that will feed into the system to prevent pressure loss. If I add 2m of 1/2 inch hose between the reservoir and the T piece then I will have additional capacity, and the oil in the hose will also be stored at system pressure. So, apart from weight and cost I can't see any other issues with remote mounting it. Sure, someone will say "all that extra hose just means more places for leaks, etc" but the reality is that it would have exactly the same number of joins as a 10cm hose, and modern braided hose is very reliable. Plus, no one blinks an eye at the fact fuel lines run the length of the vehicle, and these are often braided lines in race cars.

right.. im .6 of a second off due to circuit club only timing my bad sessions.... needs to be fixed and get on that table!! haha.. .and id have say... 130ish rwkw.. ballin'! (but in saying that there are probably 10-15 other soarers between the 1.09 and 1.13 mark anyway haha)
