Congrats Wally! Nice runs!
|
Sweet. Thanks for the videos.

Nice pics! How did it perform with the new turbo?
|
Quit well. Smaller turbo in combination with the new cam and light flywheel/clutch is very responsive, but generator wiring issues (my fault), some handling issues (loose steering joint I just found out) and lack of driver skill/experience didn;t make that track the ideal opportunity to fully experience the new lower-end powerband.
Coming friday is a trackday at the Assen circuit (famous for its TT event (motorcycles)) and we get lap timers issued there. I have adjusted the rear yellow Koni's almost full-in, reinstalled the front 400lbs springs and took care of the other issues. Plus I know my former best time from last year, so hopefully it stays dry weather and I can do a little better comparing ;-) |
Watching those drag videos, makes me shudder if someone was to hop the guardrail! Who's idea was it to plant trees next to a drag strip!!! At some point in the future some car is going to be cut in half by one of those trees! Good runs, you think any NS video will surface?

Its a poor excuse for a drag strip Jason, I agree. Good thing it was just 1/8 mile..
Today something completely different yet again: a proper trackday! Unfortunately it rained the whole day... Nevertheless Nigel (2,7 EFI) and I had a good day as the wet track was good for just finding the tracktion limits :) Tnx to AJ for making the vid (awesome for a phone!) http://www.youtube.com/watch?v=QMWhFd1iJo0 |
That is good quality for a phone! Good sound too,except for the wind.Nice footage!

Did some aero upgrades:

Cool stuff. I would like to know how the front end feels at speed after the mods.

So, there will be two major changes that will influence straight line stability and the fender gills will be hard to judge on their own... Sorry..:o |
The car will be quieter at high speed, especially with the rain gutter covers.That's a good indication that the aerodynamics is working.I don't think it will change the stability very much,but should allow a couple of extra Km/h top speed and as mentioned less aerodynamic noise.

For sure! Wenn it comes down to dropping a 1/10 off your time, even a good dump in the morning helps!:D
|
Front fender grills are just for airdinamics and better stability? i was thinking of better brake cooling...
You get more and more body mods. Some plans for running boards, mirrors, bumpers? easy weight savings are posiible there. But then you moving out away from original look. |

Yeah Mark, your already posted before me ;-)
Wrt the 'dump': I am so fanatical that I try to 'shave' 5 kg's from myself as well before Action! My wife was happily amazed and surprised I'd do that for racing, but not for my health LOL! I said you see racing is healthy, proved my point haha! Quote:
The fender vents are to lessen the air pressure build-up there. I think there is some pressure there, probably mostly from the fender end acting somewhat like a 'scoop' if you know what I mean? Hoping this will reduce lift from pressure inside and therefore also lessening drag at the same time. Quote:
Not sure my replica (thin) running board will be much of a weight saving, but if and when I do replace it, it should be the original look as much as possible. The door mirrors and trim will definately stay, but I still have a Kerscher GFK front bumper I may try out for drag racing as the weight saving of that is considarable. The Kamai air dam will probably be easy to swap over temporarily (I hope), but for track/circuit driving the original front bumper weight is 'in the right place' so to speak and stronger. Maybe strength of the original steel bumper is important for the front spoilers (air dam, splitter) too, I dunno yet how critical that is. Thats also why its an ongoing project I suppose ;) |

You can tell your wife not only is racing healthy but it improves your sex life aswell getting all excited about speed and plummeting lap times! Why me so horny? Because Race Car! :D |
LOL! Good one for www.becauseracecar.org :lmao:

My CNC-wizzard friend made a cool adjustable caster top strut bearing housing (what a word..) so I could finally set the caster equal left-right and give it some more at the same time :)
Had a full alignment afterwards and car is sooo ready for Spa and I am looking sooo forward to it! http://i174.photobucket.com/albums/w...p.jpg~original |
Nice!! That should improve grip and corner speed quite a bit! Isn't there something missing though? Nuts? Another plate?
|
Quote:
I only needed a small adjustability range (1cm which aquates to about 1 degree) to set left-right equal as I knew I wanted maximum setting in general anyways. With the small range and the bearing holder having the edge at the underside, only two small bolts are needed to prevent movement as all the car weight already is on the sliding part. The thread is in the alu plate itself which is from extremely strong alu (7075-something I believe). Only downside is I need to lift the front at the alignment shop to loosen the bolts from the underside. I have a friendly alignment shop over here, so that was no problem ;) |
Back from Spa-francorchamp and it was sooo cool to be there and even more to drive with all the german-and mostly pure race orientated bugs (and one T2!) on the track.
Since a speedo isn't there atm, just a quick reference of rpm-speed. In 4th gear: 6000 tpm = 185 km/h (116 mph) 6500 tpm = 200 km/h (125 mph) 7000 tpm = 215 km/h (134 mph) In 5th gear: 5500/5600 tpm = 220 km/u (137.5 mph) http://www.youtube.com/watch?v=TEiwO_ZGVa0 Unfortunately I heard a weird noise after 40 minutes and in looking at the above video myself, you see the back pressure gauge not reacting anymore at about 30 minutes. I just checked and indeed, the hose has been blown off from the connection at cylinder no.1 exhaust header pipe and in hindsight probably causing a pretty good imbalance that took 10 minutes at WOT to take my main bearings out. Drove home without problem though with still good oil pressure and even made good milage (25 mpg or 1 ltr per 10 km) Today let off the oil and there it is indeed: nice shiny flakes of alu...:( http://i174.photobucket.com/albums/w...analyse001.jpg This sucks pretty good as I was just as exited to go to VW Action in 2 weeks as I was to go to Spa. Hopefully I can have things repaired in time but I fear that that much bearing remains may have done more damage to other engine parts too. Its going open asap to determine total damage. Two weeks and counting... |
thats bad luck mate, hope you can get it sorted for Action. see you in a few weeks hopefully.
|
That really sucks.
|
For all the power and use you put in you car, might some steel backed bearings be in order?
|
I think all engines should have steel backed bearings btw ;-).
Originally only the center mains are steel backed as you know and the Mahle bearings I ran have steel center main backed bearings. Unfortunately, there isn't much choice either. You use what you can get. Only the first main (flywheel thrust) seems damaged and even though I ran 0.015mm (max factory), I think for circuit driving like I did (regularly 7K+) even a little more end play should be considered with the 'new' Mahle brazil bearings. Everything else seems fine as the filter and the soft first bearing layers seem to have taken in most debris. Cam looks unused still (Tool steel lifters) and rod journals are super smooth as well still. Tomorrow crank will be inspected. Barrels have some scorings, but maybe a light hone can help some if they don;t go through the nikasil layer... |
Hope you get her buttoned back up in time!
|
Sorry to hear that Wally... you will come back better than every! (as you always do):)
|
It was good to see you there Wally! I showed up just as you were on your last lap. Sorry to hear about your bearings! I really enjoyed the video! After about 17 minutes you discovered the racer in yourself and seemed to be pushing the Mythbuster harder than ever before! it is really,really fast! Ulrich Eckstein sells steel backed mains from Glyco (Glycodur in Europe),maybe he has a set in stock for you? You asked me about my mains...I looked at the box again,and there is no brand mentioned.IIRC though they were Kolbenschmidt from Brasil,then coated by Calico.I have a set of unused GOP (Gen O Parts Germany) mains in STD,center main is steel backed that you can have for free if you want.I had gotten them from Remmele.However the forward main that fits under the cam gear is oversized in outer diameter,it did not fit in my case.Thatīs why I didnīt use it and went with the mains I bought from Jake.

great to see the car at spa wally - shame i didnt get to meet you! sorry to hear about the engine - fingers crossed for the crank to be ok!
spa was a fantastic show - probably the best ive been to! good luck getting the motor back together for action Deano |
Thanks Deano. Pity indeed we didn;t run into each other, but its a huge site and easily to be at different locations. It was a busy saturday for me at that as well ;)
Crank is fine (no imbalance) and could be polished within 'loose race-spec' :lmao: I could find new bearings and I am cleaning everything now. If I don't f*ck-up the assembly (this is not a 'normal' engine), I should be good to go on the boat with Clyde Berg and company to VW Action ;) 2 1/2 weeks and counting... |
that's great news! wish i could make it to action (especially as my bug will be on the road!)
have fun! |
Glad things are looking up Wally, I'll definitely try and make it over to Action!
|
Luckily you caught everything early enough that no real damage was done, lucky! Hopefully it all goes back together smoothly in time to kick ass at the next event :)
btw, how much caster are you running on the front now? |
Quote:
I was thinking maybe its the 944 Cup (M030) spindles that I'am running that give the unfavourable caster. A-arm pick-up point, strut mounting and the wheelbearing shaft are all in line with these. Maybe a stock spindle is different? :confused: High speed (>125 mph or 200 km/h) changing directions was still a bit nervous as you might see from the vid here and there from my steering corrections, so its either more caster or I really need a wing with a bit more serious vertical side pods. Apart from Thomas, who runs a very cool body extension as a wing (which would hinder my intercooler function I think), no other cars ran over 125 mph on the track as far as I know, so there is little comparison. There is a good thread on the cal-look lounge about high speed and aero for beetles at the end of the 1/4 mile and the consensus seems to be that when approaching 125 mph, beetles get into aero trouble and get unstable. I'am starting to see the resemblence here with my own experiences more and more, so not sure more caster will help if its really aero related. Would be cool to talk to you at Action 4sure Rich! |
Was nice to meet you Walter. Hope your car will be ready for the next challange!

Likewise mate! Tnx for the pics :-)
Good luck with the nice score on the brakes you got at Spa! |
Well done on your PB at the weekend Wally :)
