Excellent; I would really like to do that as well.
The Nurburgring in under 10 minutes is kinda fast I thought. Jeremy Clarkson had to practice 2 days to do it in under 10 min and that was in the newest 200hp Jag...
His lady (!) instructor did it in her first lap with his car: 9:37 or s/th I believe and it was a diesel...

Yeah, Sabine, what a chic!

I understand it you saw that Top gear episode too

[Chris Percival]

Of course..

I wish we could see Top Gear over here. Speed TV is now showing 5th Gear and I love that show.

I get BBC World on digital cable in Toronto, sure enough I saw my first segment of Top Gear ... LOVED the comparison between the Bobsled and the Mitsu Evo ... who can get down the side of a mountain fastest ... the Evo lost by a second ... WOW.


Back on topic ... I've priced a few setups now ... Autocraft 2 stage - 495 USD, CB DS pump - 99 USD, CSP DS pump - 169 USD.

I've heard the CB pump does not have a big enough scavange stage, and oil could still accumulate in the case/heads ... is this a big deal though ?

The idea would be a constant supply of oil to the engine during hard cornering/acceleration/deceleration and I'm sure the CB pump can handle this as the oil supply is coming from the DS tank (12 qt ?) ... correct ?

I was considering an accusump but the last thing I need on the track is the accusump discharging 3 qts into the engine and then taking time to recover the oil, just as the next turn approaches

Thoughts ?

For real track use, I'd say dry sump always.
Be carefull when you buy a type 1 pump set-up 'as is', because I think that the oil passages are not lined up correctly for a type 4 case.
Also cam wheel clearence is a concern if you do not have the stock cam or a Schleicher cam where the cam gear is riveted. It still may need clearence anyway with some oil pumps.

Also I think its best to use alu quality pumps because of thermal expansion in relation to oil leaks.
Do you know what make the CB and CSP set-ups are?

Walter

Hello,

Totally OT first: I love TopGear, it's an awsome show. And, I've seen the bobsled vs Evo comparison three times already and still can't get enough because I went down that track in a bobsled!!! :agree: Went up there in a damp mini-van though!

Back on topic, the scavenge-side off a dry-sump pump should be at least twice the size off the pressure-side. So, 2:1 at least!

Cheers,
Richard

I have an email in to CSP-USA about the pump specifics .. you can get 3 types of pumps ... 1 for a 3 bolt gear (T1), 1 for a 4 bolt gear (T1) and 1 for a T4.

I agree on the Alu composition of the pump vs iron for sealing.

When I get the info back, I may choose the CSP T4 pump because I just want a constant oil supply for the engine .... not really concerned now that the heads/case may accumulate oil. I'll judge its performance this year and if unsatisfactory, there is always the Autocraft unit for next winters project !

So that's atleast 4 of us trying make an impression on Sabine, in Beetles

As of now, the Nurburgring is officially excempt from ever being 'Off Topic'

10mins is pretty quick Wally, If I expected to be much slower I don't think it's a good idea to be out there.... So no busses I hope to get some real track experience by going along with Chris to a UK circuit or two. I live near Oulton Park and a mate owes me a track day (for helping with a T4 top-end rebuild/carb conversion I did on a Westy last summer) He is building a BTCC styled Rover 820turbo..

The last CB pump I fitted to a T1 had both the 'CB' and 'Shadek' logo's in the casting. It appeared to be of a very high quality. It was the slightly higher price of the D-S pump on the CSP site that got me wondering about it's origins. I'm up for using ceramic lifters, I like the stock style of the Schleicher cam gears. I guess all 3 may fit together, but..

I've not used a Melling style pump in the last 13years for the reasons mentioned.

'Looking forward to what info Sandeep's quest turns up.

I would like to fit an oil pre-heater into a D-S tank (or possibly in-line) to reduce cold wear if possible. I suppose this is still an option for a wet-sump.

I'm off now, to watch the RUF 911CTR 'Yellowbird' Faszination On The Nurburgring Mpeg (again!)

Thats a great vid that, start memorising the corners!

[MattKab]

I'll try to watch it daily for 18months

The Nordschleife from above

Maybe 20mins is more realistic? And 10mins the ultimate goal. How does that sound? Surely there has been hundreds of laps by 1303? I've nothing to compare with.. Has Remelle Ever had a go?

I regret not opting for German language at the age of 13 Searching for lap times only turns up sub 9sec cars.

It only costs €2 to go round by Bus so busses are more than welcome

A 5 lap ticket costs €60 (special offer 2005) I better go and do some work on my case...

1. hi
2. im going to have to make a windage tray for my T4, ill take some photos
3. there are two race days in the SEMSEC series where the Aircooled cup cars are competing that have a track session attached 2nd May and 13th August at Lydden Hill
check out www.semsec.org and http://www.semsec.org.uk/trackdays.html

and id love to do the ring

[MattKab]

By Lydden, I'm halfway to the ring..

Jimby, I can sort a pic of the 914 windage tray, If that helps you..

I could head to Brands' for a watch, 2nd April

Matt

[jimby]

yes please, you can email it to jimby@hotmail.com
