My other 1303 GL

[Wally]

Nice car for sure!
Steve, what is the benefit of a fuel damper?

[H2OSB]

Two amazing looking cars! Love the idea of the oxyboxer. Unfortunately for me, I can't install an oxy for the same reason I can't do a Suby mill...don't have the guts to cut up my car. Maybe if I could just find the right radiator set up.....

Hi

I needed a fuel pulse dampener because Im running ID 2000 injectors and when they open & shut they cause a chatter in fuel line which causes a rough idle.

John, the idea of going Oxyboxer is that will be essentially an air cooled motor, a WBX with no water jackets.

When I sold my 1302 and fitted an air cooled motor in place of the WBX all I had to do was fit a new spare wheel well to get it back to standard.

I knew that. I guess I gapped out a bit. I was looking into an Oxyboxer crank into a T1 for a while, but I've gone pretty far down the T4 road, so I decided to stick with that. The jacketless WBX makes a nice motor, I just don't have any of whats needed to build one and don't feel like cutting my losses with the T4 parts.

Anyway, both you and CaveDarter have nice rides!

tnx! learned somethink again :-)
You run E85 now (because of the 2000cc injectors)?

[Steve C]

Hi

I do run E85 but I have a flex fuel sensor so I can run 98 RON if I have to but I have two E85 servos about 5 ks from my house and a few up and down the highways.

My son Dave AKA Cave loves his bug, have you seen this video of him? https://www.facebook.com/NittoTyres/...2012700536507/ He works in marketing with Toyo and Nitto tyres, he convinced me to fit Toyo R888Rs to my bug, hes running Nitto Invos on his bug and Im also running them on my 180SX.

I also fitted an eBay intake temp sensor, seems to be accurate.

Great to see your back at it Steve

Hi

I had a little mishap with the motor but it was fixed under warranty, it picked up a big end bearing.

I'm going to do a 1/2 mile run in September at Gunnedah in rural NSW Australia on the 1st of September, I cant wait.

Hi

Just got back from running the 1/2 mile at Gunnedah, I won my class and finished 37 out of 80 cars, ran at 231 kph

the runway at Gunnedah is very bumpy near the end, I think Im going to look at some front aero, it was getting a bit hairy at about the 700 metre mark and the car squatted the rear the whole length of the track

not sure if this video will play https://www.facebook.com/davejcarter...811864908/?t=0 I ran over some cement dust in this run and I thought it was clutch smoke so lifted off

I put a new radiator in the week before the event, it worked perfectly, I used one from a 944 Porsche, really nice fit, thanks to boys at Westside for helping out again with fan mounts.

with my intercooler temp gauge I was able to keep an eye intake temps, we used the Frozen Boost ice box and I again short circuited it to cut out the front mounted radiator, at the finish line intake temps were 90c after the turbo and 22c after the inter cooler, I was leaving the line with after cooler temps of around 18c

We setup the launch control and on the first run I fried the clutch, I nearly put it on the trailer but I let cool down and then I granny shifted it from then on.

So Im going to get hold of a front air dam, put a larger ear housing on my GTX3076 turbo as I went from a .82 to .63 trying get some better response when it was a 2 litre motor so I will go back to a .82 rear and go for some more kWs and of course I will see what I can do about a clutch, the Aussie dollar has gone south against the greenback so I will try something local if not I will see what Kennedy can do

[Wally]

Great result Steve! The bigger motor should be able to use the bigger turbine A/R without too much - if at all- added lag, me thinks.
GL with the clutch.

[Steve C]

Thanks Wally, going to give the 1/4 mile a go tomorrow night if the weather holds. I still have the 15 inch cookies on with the ET streets

[Steve C]

Hi

The 1/4 mile go trained out, I will try again to have run in few weeks.

I wrote an article for club magazine about the event

½ Mile racing at Gunnedah Airport
On the 1st of September I ran my Beetle at the Race Revolution ½ mile at Gunnedah Airport , I had previously run a similar event at Cooma Airport over 1000 metres in 2014 and 2015. Cooma Airport didn’t want to have the event held there anymore so the organisers had to find a new venue. The new ½ mile distance was chosen as it’s an international distance used by other land speed racing bodies and Gunnedah Airport didn’t have the required slow down area at the end of the racing surface for 1000 metre racing.

I’ve had a few issues with my Beetle like running into walls and breaking motors but I managed to get it running in time to run at Gunnedah. While it was off the road the Subaru WRX STI (EJ207) motor was bored and stroked to 2165cc and made 305 kW at the wheels when tuned by DVS on the Central Coast at Somersby. Because the motor is turbo charged it had to run in the classic class 2D for vehicles between 3000cc and 5000cc.

Gunnedah like the rest of NSW is in severe drought so it was good to travel there and spend some money in local businesses; some businesses that sell alcohol received a fair bit of my money. The event organisers nominated a local charity “drought relief for kid’s fundraiser”, many racers including myself donated to this cause.

So after spending lots of time putting my Beetle back together I also had to finish putting my car trailer back together which I had taken off the road to refurbish. We left Friday morning for the drive up to Gunnedah towing an untested car trailer, good planning and workmanship prevailed and we arrived to a very wet Gunnedah airport, a friend of mine Andrew who is also a heretic and drives a Subaru powered 71 Fastback travelled up with us, we met up with another VW racer Glenn Torrens in his salt racing L bug (1303S). After having the car scrutineered we went and checked into our accommodation and then went into town for some refreshments.

Saturday, race day was fine and was ideal for racing with light winds all day. I have an Adaptronic Modular ECU in my car which not only controls fuel, reads and adjusts tune according to E85 concentration and ignition but can be used to operate launch control. On my first run with launch control activated I rolled up to the start line, put my foot down flat and the car went to 5,000 rpm and made 2 psi boost, as the car moved forward the launch control disengages via signal from a speed sensor in the transmission and full RPM can be achieved which on this day was set at 7,300 RPM. I got a bit exited and fried my clutch, I came back into the pits and was going to put the car on the trailer but my son convinced me to let it cool off and give it another run without launch control.

After everything cooled off I was able to do 4 more runs taking it easy and win my class and finished 37 out of 80 cars, best run was at 231 kph and 19.5407 seconds.

The runway at Gunnedah is very bumpy near the end, I think I’m going to look at some front aero, it was getting a bit hairy at about the 700 metre mark and the car squatted the rear the whole length of the track even with short 30 mm torsion bars. I ran the car on 15 inch Porsche Cookie cutter wheels with street tyres on the front but Mickey Thompson ET Street drag tyres on the rear, I normally run on 18 inch Porsche wheels so the car sat a lot lower than normal, I also fitted a V Force whale tail to the car for the event.

I put a new radiator in the week before the event after it got a little warm driving back from the VW Spectacular, it worked perfectly, I used one from a 944 Porsche, really nice fit, thanks to the boys at Westside Mufflers, a VW Nationals sponsor for helping out again with welding fan mounts to the radiator and turning my stupid ideas into metal once again.

I have an intercooler temp gauge in the car which shows in and out temperatures, I was able to keep an eye on intake temps, I use a Frozen Boost ice box which I fill with ice and I short circuited it to cut out the front mounted radiator which I run on the street to cool the PWR water to air intercooler, at the finish line my intake temps were 90c after the turbo and 22c after the inter cooler, I was leaving the line with after inter cooler temps of around 18c and there was still ice in the system after the run.

So I’m going to get hold of a front air dam, put a larger rear housing on my GTX3076 turbo as I went from a .82 to .63 rear housing trying get some better response when it was a 2 litre motor so I will go back to a .82 rear housing and go for some more killer wasps and of course I will see what I can do about a clutch, the Aussie dollar has gone south against the greenback so I will try something local if not I will see what Kennedy Engineering who supplied my current clutch can do.

So as far as I’m aware I hold the ½ mile land speed record for an under 5000cc Beetle in Australia

I just uploaded a video of my best run on the 1/2 mile, you can see Im granny shifting and without launch control it didnt make any boost off the line, its making full boost when you hear the screamer https://youtu.be/ZM1qHUNbBw4

Nice! So, an even better speed would be very possible?
You are indeed granny shifting! Short shifter kit would help also I think?

BTW, what RPM are you at the timed 231 km/h?

[Steve C]

Thanks Wally

I was taking it easy I didnt want to harm the clutch by getting into too early after shifting.

Do you know anywhere I can buy a short shifter at reasonable price

According to a gear ratio calculator I would have been doing 6187 rpm, I was shifting at around 7,000. The gearing was short because of the 15 inch wheels I was running

The rev limiter was turned down to 7300 rpm because of the small turbo
