I might be interested to drag my knuckles around like the rest of them just for one night and continually be asked what the hell is my car?

There's a firm committment from drivers of the following cars:
2 x WRX powered beeltes
4 x 1914/5/6 cc powered beetles (Depending on your maths)
Definitely some 13 and 14 second cars here.
I haven't started my oval since I put it back in the garage when I arrived home from the VW Weekend in Warwick. I wonder what the difference in 1/8th mile time will be since the car will be exactly the same. Day vs night. High altitude vs close to sea level?

CT ive got a bad case of the Flu and feeel like shit
I was hoping for next week to be OK buggar it
fullnoise ·
It sucks having a cold/flu in hot weather.
If you can drag yourself off your death bead Ill be there around 4:30.
I haven't heard the lovely sound of webers since the begining of the month. It was nice driving the car around tonight.

See you tonight CT

The flu has got me as well so wont even be there as spectator.
Go hard guys and please post some times.
They dont even ask for rego papers anymore but I always take them anyway. Remember to get your paper work before going over the pits (like I did) as it annoys them slightly!

Jak 13.3 @ 102MPH
CT 15.2 @ 85.9MPH
David 16.6 @?
I was a bit disappointed in my times and MPH. My launches were crap. 60ft times were either high 2.0 or low 2.1.
The MPH was 85.6 to 85.9 with 135 main 175 air. Then with 130 main 155 air it was 85.79. With 135 main and 155 air it was 85.64. So it doesn't really matter what jets I threw at the thing it still felt the same and the MPH reflects that.
The time I did in the NSW Dutton rally at WSID was 14.6 & 89 MPH with a 1.9 60ft. At that time I'd had 2 days of competition under my belt and I could launch the thing without thinking about it. The tyres were also hot then because the car had just completed some laps of the racing circuit.
Last night the car was heavier with a full tank of fuel, back seats mats and proper door trims not aluminium. So that might have slowedit down a bit.
Anyway that's a good yardstick for comparison. I'll matchport and fit the shorter angled Stan Pobjoy cast manifolds now. These things are 44mm at the top to suit 44IDFs rather than the usual universal fit 48mm aftermarket jobs. They are also a nice stright funneled design. So we'll see what the difference is at another wicked wednesday in November.
The highlight of the night was watching Jak have a run against and R34 Nissan GTR or with the big exhaust etc. Both launched hard and looked quick. Jak got him off the line and did a 13.2 and the GTR was madly trying to chase him down and did a 12.8 but Jak was first across the line and took the win. It's great to see a standard bodied beetle beat a modified GTR!

Cool to hear dude. Sounds like much fun. I did exactly the same time in my 58 last Friday with a slightly higher MPH and from memory the engines are similar spec, other than mine only running 8:1 compression. What were the weather conditions like?
What boost is Jak running? Think I'll have to step up the VWRX attack next year....😁
Video?
fullnoise ·
Hey Ruben,
Jak just runs the stock standard boost which is about 9psi or something. He says he can turn it up with an allen key if he wants but never has. He says it is frightening enough as it is.
The weather was probably mid to high 20s.
Video? It would've run out of tape on my run! Nah we didn't bother.
CT
reub ·
Hmm ok. Interesting. Gearing would also help I'm gessing...
When I ran VWRX it did 13.09@105mph running 14lb with only 2 hrs street tuning under it's belt - and it's not scary enough... 😂 I want at least 11's out of it yet - so 20lb is on the cars.

Well done Jak and well done CT. They are still good times CT and bloody good 60ft time considering your final ET. Think of it this way, how soft must I be when running a 12.9 and a best 60ft of 2.2 😊
It is practice though and I only get in my car once a week and then Im still not practising launches.
Next time Im in for sure, dont want to be the lonely VW again.
david777 ·
It was good to see CT and Jak in action. I only did a 16.6 @ 78.5mph. It was only my second time to the drags. It was more than a second quicker than last time, but still plenty of room for improvement.

Hi CT,
Good effort to you guys!
I'd like to see your old, and new manifolds.
I know BugPack makes some really good IDF manifolds, but I cant remember wether they are 48mm at the top.
Those changes to the air corrector were prob a bit big to see any trend.
Perhaps steps of 0.1mm may show more improvement?
What venturi?

Buggar any plans to go again B4 xmas ????
times r good Ct

Hi Dave, Dave and er Dave,
Perhaps I should use handles instead!
david777. Nice video. Your car looks hot in the photos and in the flesh. I wish I could say I improved 6/10ths on the night.
dangerous. The vents in the 44IDFs are 36mm. I've had the car dyno tuned a couple of times. Last time I didn't give a brief to the tuners, hoping they'd come up with something different. They tried different emulsion tubes and main/air combos but ended up confirming that the out-of-the box combo of 135/175 jets in F11s is the best compromise.
Some cars pop can carry-on if the jets aren't quite right but mine doesn't seem to be too fussy. When in Warwick I choose 130/175. When supersprinting and I know the engine will get really hot I choose 135/155 otherwise I get white spark plugs.
The reason I tried a few different jets is that the car feels good but not quite as happy as it could be.
I've attached a photo of the "Big Beefy Manifolds" I'm currently using and the turbo tops I now use for freeway driving or commuting to and from work in heavy traffic. This set up richens things up and leaves a fuel mark on the bumper unless I change the jets to 125/155 where it leaves no mark and will still rev to 7000 cleanly.
vw54. I should be able to port and bung the manifolds on the mid November. So after that looks good

Hey CT,
Here's a tip for you that may boost your torque and only cost you a couple of bucks and a bit of time.
Looking at your intake setup with the turbo tops, it looks like both sides are separate to one another (it may not be but from the photo it looks that way).
If they are separate from each other then you can pick up some nice torque in the mid range, just by joining them together.
You can use pvc pipe and fitting (available from your local plumbing supplier) to make it up, and then if you like it you could have it made out of alloy, although the pvc is fine the alloy would just look prettier.
Don't worry about heat affecting the pvc, if your motor got hot enough to melt the pvc then it would have to be on fire.

I might try the PVC. At the moment I've just got some fan housing ducts, some IDA velocity stacks and foam sock filters all held together by a couple of hose clamps. I want to keep things easy to remove so I can swap back to the normall dellorto style air filters in minutes.
The only problem is that my engine is rich at 2500 rpm due to fuel stand-off. It's just a little more obvious with the turbo tops on. But I can live with it.
Have you been down the strip lately?

Craig Torrens ·
What are the advantages with the turbo tops ?
are the "beefy' manifolds ported to your heads ?
fullnoise ·
Hey Craig,
The only reason for the turbo tops is to reduce the carby noise on long drives and when I just want some peace and quiet. They reduce the carb noise a hell of a lot. You even start hearing the fan!
I don't think they're great for performance and almost ran them down the strip last wednesday night but we were about 3 minutes too late. My bet is that they slow the car by half a second in the quarter.
The big beefy manifolds were ported by DRD and I got them at the same time as the heads. They may be responsible for a great improvement in torque over the last combo but I'll find out when I put the small manifolds back on.

LIFE IN THE LOW LANE ·
Make larger air boxes to go on top of your carbs if room permits. Then run them together to a joint plenum. From there route a some piping to a nice big Air filter where space permits. This will reduce noise and would prolly work better than your current set up without hampering economy/performance as much.
fullnoise ·
Good thoughs with the airbox/ air cleaner.
There must be a science to it since all modern cars seem to have such long air intake paths yet I doubt they'd do it if it strangled the horsepower like I suspect it does on my car. Mind you I'm sure induction noise is like red paint; both make your car faster without the need for mechanical modification.
I've always liked the cold-air-box idea. If the small manifolds are not a step backwards they'll stay and give me room (1.5 inches or so) to look at a cold air box. with a decent volume.
Like exhaust theory it can get quite complicated to figure out the ideal airbox volume I hear. I've heard of people dyno testing with an inflated balloon in a large airbox. They simply alter the volume the balloon and see how it affects performance. Then they deduct the baloon volume from the airbox volume to come up with the best airbox size.
It would be nice to feed the boxes cold air from either side of the inner pressing below the vents under the back window. But like usual I'll have to move a couple of things to make room for that.
The cold air boxes will have to miss the hex bar linkage anchor points and be angled to clear the engine lid. They'd have to mount the same way as the dellorto air cleaners so I can access the jets easily. I think some quick release pins on the deck lid will also be necessary.
I think I'm turning into a Gunna!

I run my bike at willowbank on a semi regular basis but I haven't taken my bug to the strip yet, but I'm gunna.
Are you running velocity stacks under your turbo tops?
A good example of airboxes not hurting power is my motorbike. I'll explain.
I ride a ZRX1200R, these bikes have a cult like following in the USA, and as such there is a huge amount of tuning done to them over there.
The airbox design on these is not the best and has been described as terrible, however testing with the same bike on the same dyno on the same day, with airbox and without and with jetting optimized for both setups there was virtually no difference between the two.
The point is so long as your not restricting the breathing and you can optimize the fuel curve you won't lose any power.
An interesting thing I read about airboxes is that some are designed to slow the air down and gain more air density. This type of airbox uses quite a small inlet, from memory as small as 40mm on a 2L inline 4.
