Interesting mods all around. A couple questions from the engine picture:
1. Would you expect any performance issues if the #1/#2 header tubes were not clamped like you have them? Mine are not and freely slide...
2. Why isn't the crankcase breather box vented back to the carbs?
Thanks, Bill

Glad you find the mods interesting ;) Actually, there wasn't enough room to lay it all down... :(
As to your q's: 1) No, no performance issues, they may just leak a bit over the slip joints if you won't clamp them. Actually they shouls be welded, but I wanted the option to use this header on another engine in the future, so I clamped them.
2) I never had a need to route the breather box to the intake. Some say the oily fumes make your octane rating go down and with 10,8 Compression ratio on pump gas, I didn't want to take chances for now.

Thanks,
Walter

Wally, nice to finally see pics of your ride, it looks great :agree:
Im doing a 75 1303 as well :D

One question, what mods do you have to do to use 100mm cylinders
from a 964 to make them work on a T4?

Wally February 21st 2005 12:17

Thanks,
Here's all you need to know:

And the thread that I was actually extra motivated by to finish the project because 'somebody' on GermanLook.com said it wouldn't work...: (remember? It got so out of hand, Alex had to close the thread.)

Look at the date: that was two years ago!

Wally,

You stated in your vehical details "944 turbo Cup spindles with VW Golf (rabbit) struts with Passat rear springs on 1303 perches".
I thought that rabbit struts would not fit the 944 turbo(951) spindles because of the wider hole spacing on the 951 spindles. Did you modify the struts or the spindles? If so, how? I am currently looking at how I am going to add 1986 Porsche 951 Bremo calipers to my 75 Super Beetle(1303).

Thanks,
Randy

Wally February 21st 2005 15:41

Yes, obviously those parts don't fit straight away together. Unfortunately, coil-over sets for turbo Cup struts to a 1303 don't exist either, so you have to carefully and conciously let a proffesional weld and modify (the struts that is) everything so it does fit.
You also have to understand that the suspension modification was done more then 12 years ago, when these parts were still rather new and no-one ever knew what I was talking about...
The car has just passed its yearly inspection again with flying colours, so the inspectors always seem to approve from a safety point of view. Not that that is the measure for things, but it does give some confidence.
So, yes, it is all custom made. No bolt-on solutions with these parts, especially not in those days :rolleyes:

Wally July 15th 2006 15:01

Updated the info with some new pics from last track day with the cars new wheels :D

Thanks for the nice day, Walter and Nigel!

juse August 9th 2006 13:38

How did you end up using Passat springs? And from which generation Passat are they?
You see I`ve been trying out different springs with my DIY struts.
What I need is a pair of springs with stock diameter but quite short and soft enough...

That picture is a bit old...today my little brat has a little more healthy steel on her...
Justin

Wally August 10th 2006 01:52

Passat 2-door model (Coupé) of about 1978 it was I believe; one of the the very first models anyway. You'd want the REAR springs of them for you 03 front struts ;)

Those can easily be used in a stock strut and lower about 4 cm and be 25% stiffer than stock.
I have however also used Golf 1 struts and lowered the bottom 1303-perches some as well. I think its about 10 cm lower now, but because of the large diameter wheels it doesn't look that low.

juse August 10th 2006 07:35

OK, Passat springs are now on my shopping list.
How about Golf MkI or Polo MkI rear springs? Has anybody tried those and do their dimensions fit??
Justin

Wally August 10th 2006 09:26

Do you really think I went to the trouble of specifying that exact springs if much more easy to find Golf or Polo springs would fit in a stock 03 perch? :rolleyes:

juse August 10th 2006 10:43

I understand that means you already knew that only Passat springs will fit? Am I right?
Justin

Sandeep August 10th 2006 12:41

Hi Walter,

I just watched the video ... very enjoyable :agree:

Can you describe what kind of speeds you obtained on the track ... how were your tires and brakes ? How did the gearbox and engine perform ? I noticed a few puffs of smoke from the incar video ... any idea what that was ?

Looks like you had a lot of fun on the track. Is there anything you may consider changing in the overall setup of the car ?

Thanks,

Sandeep

Relatively low; I have a digital speedo which is very accurate; With the 2,4 I did about 175 km/h at the straight, but this year with the 2 liter we only reached 150 km/h max but it was with only on 3,5 cylinder....(hence the smoke...)
Funny thing is that from the video it seems not that fast, but when your inside, it sure is thrilling!
Quote:

Very well, but the JE pistons were used when I build this engine and it turned out that the oil scraper (control) rings of at least one cylinder were too far gone. One cylinder consistantly had therefore a lot of oil blow-by and greased that one plug a lot. Only when the engine was hot, it ran flawlessly :rolleyes: but I have removed the head on that side and it appeared that the exhaust valve had 2mm carbon build-up on it...
After changing out the oil control rings, the smoke has gone. Learned a lot from that experience!

The gearbox shifted mucho better without any grinding, but the shiftrod needs to be adjusted somewhat I noticed for more precise shifts in some gears.

It handled very well actually, but ultimately, I want to install a rear sway-bar (have one, but because of my wide semi-original 915 tranny-carrier, it doesn't fit :( ) and a slightly more lower setting in the rear.
And I may want to try the Kamaii front spoiler and some other small changes; not because handling is poor, but because I think it may get even better :D

Greets,
Walter

Wally February 13th 2007 17:47

We had great fun at the dyno last year:

http://www.keversite.nl/fotoalbum/fotos/37419.jpg

Result were better than expected!
With 122 hp @ the wheels (about 15% loss from the 915 tranny equats to about 143 hp at the flywheel) for the mild 2056 cc (Webcam 86 and 1:8,2 CR!) I was more than happy. Tuning the DTA ECU with the laptop and dynobox was done by Blue Thunder (thnx Robin) in the back of the car with laptop on a bucket :D

http://www.keversite.nl/fotoalbum/fotos/37416.jpg

http://www.keversite.nl/fotoalbum/fotos/37417.jpg

On the way back from DasDragDay4 @ Bitburg, germany, the engine managed (pun intended) 38 mpg!

Awesome vid:D

Hi Walter
Just read your blast at EBI, a very nice timing slip.

Can I ask how your idle is, as I have a similar sized engine although type 1 with a DTA ecu. I noticed you don't run a ISV. Do you get differing idle rpm dependant on the engine temp.

thanks

Thanks! But since I filled out these forms, engine is now a bit 'uprated' :D
So I doubt you have a 2,7ltr Type 1 engine? :rolleyes:
ISV is Idle stabilizer valve or something?
No, with individual Throttle bodies any idle control valve is not possible afaik.
As of last week, I have found the 'idle speed control' function in the DTA S-program and that really works! It keep my idle at the preset rpm with automatically adjusting the idle advance by the ecu. Also running sequential also improves idle mixture. My new S60 ecu is capable of this as well, whilst the former E48 was not.

With the E48 dta ecu however, the engine ran quite stable at idle as well. You just have got to keep fuel and advance even around idle rpm-range. With larger duration cams, its always more difficult to keep idle as stable as with milder cams. The 2056 had a mild cam and that helped also I suppose.

Cheers,
Walter

Edit: just read your site: Very cool car and extremely nicely detailed (I suck at that).
What did the dynoíng at John Maher say on hp and torque of your 2276? (what's your cam?)

65Cabby July 28th 2007 13:04

Thanks Walter

Mmmm yes you have been tinkering..No mine is a little short of 2.7

I didn't realise that you couldn't use a stabilisation valve with dual throttle bodies.
I think I cracked it today, I've been playing with the fuel and advance at zero throttle. My map is incremented 500,1000,1500 and it now purrs at 1100rpm. I'll know in the morning when everything is cold if I can stop playing as it has made it a little difficult to start. Or I should say before I didn't need to touch the throttle until it fired but now I have to give it a little.

Other than the idle I can't fault the dyno work, it pulls from zero throttle in any gear. I've just got back from a 600 mile trip so I know it goes well :)

I had read about the idle control of the S60, the E48 is a little old now.

The engine is 2276cc but with AirCooled.net Super Squishie pistons, they have a funny crown to the top of the piston. The cam is their's too and doesn't come with any details as to lift and duration. the strange thing is it only has 20deg total advance but that usual for a Squishie engine apparently. The map is therefore very flat unlike the fuel map.
On the dyno it peaks at 6500rpm at 163bhp, the torque already at 132lbft at 2000rpm and peaks at 4500rpm.
I've not had it on a rolling road yet to see what it looses from the box and my only run at the 1/4 I messed up the lights and let the guy get 3-4 car lenghts away before I realised it was green. that gave me a 15.39 so I know it's got lots more and is quick.

Richard

Wally July 29th 2007 04:40

Thanks for the info. Very nice stuff!
Your map at idle could use a little more closer spacing in rpm setting: I have re-set the rpm range to 750-1000-1250-1500-2000 etc

It makes idle tuning more accurate.
I guess the squishy cam makes sure the intake valve opens a little later so it just does not touch the dome on the squishy piston and just follows the piston going down (or something like that). Cool stuff!

Cheers,
Walter

Walter-Your car is an interesting read.I have a 2.7lt Type 4 in mine which I am in the middle of Injecting.What ECU is that you are using?Is the crank trigger wheel from another vehicle or custom made?My ECU uses a MAP sensor and is giving me heaps of agro because of the mild cam and dual 48mm Throttle Bodies.How many inputs does your ECU need to work?Keep up the good work.Regards Gary.

Its from DTA, the S60 model. (www.dtafast.co.uk)
Quote:

Its a 'custom' laser cut wheel which a friend made, which I bolted to the rear of an 'equaliser' steel poully (sp.?) then had it balanced. Here's a pic of it (if you can look closely..)

With individual Throttle Body's, I would forget trying with MAP as base load. Its just not designed for it. It may work for some-one, but I wouldn't bother...
How many inputs? Well, air temp, water (=oil) temp for cold starting, VR signal from crank and TPS for load. Thats about it, but that is true for most any ecu.There are some more pics on keversite.nl of just the engine (parts):
http://www.keversite.nl/fotoalbum/my_photos.php?id=3349

At the moment, she runs sequential (cam sensor is working)! and I did 10 liters to 100km at a steady 70 mph all the way from the way back from EBI where the heavy car ran a 13,82 sec on the 1/4 mile!

nbturbo August 3rd 2007 22:02

A good collection of pics there-thanks.Good idea with your muffler-never thought to bend it in the middle to clear the body-made mine as well and had to make it a lot shorter to keep body clearance.Yes I am using all those inputs as well-with a single wire O2 sensor and the MAP.Think I have got the MAP beat now-made a small alloy tube with 4 small inlets and a 6 mm outlet and fitted 4 small one way check valves to stop each port robbing the rest of vacuum.Idles good now with 12 to 13" Hg and I fitted slightly smaller injectors-from 20.4 Lbs/hr to 18.25 lbs/hr.You would have to be very pleased with that 1/4 mile time and good fuel consumption as well.Looks like a pretty good package to me-good all rounder.

I would really suggest installing a wide band 02 sensor. Tuning is everything, especially with our large engines. The LC-1 from Innovate is not that expensive and worth the cost. The cheapest hp you will gain by far imo.

Indeed! Especially realising that the car with me in it without interior and tank half full weighs in at 2225 lbs! Allround performance is exactly what I am after: it does a decent time around our local track too :D

Wally February 27th 2008 17:24

Just realised Aart-Jan shot a 10 second video of a blast down the straight at Zandvoort last year with the 2,7 engine:

http://www.youtube.com/watch?v=bD4WRCN4cLE

Unfortunately Aart-Jan has held the camera 90 degree tilted and compares the sound of the engine with a Jet-ski??:confused: :D

aartjan February 27th 2008 17:35

That was the first session, credits for the cam-work go to Robin. ;)

Won't forget that last session when I had the chance to be your passenger, for multiple reasons! :eek: Oh man, what a ride!

Wally February 28th 2008 18:09

Oh, yes its Robin's fault (of course :D )

You certainly had a rememberal run...pity the rod didn't wanted to play anymore. The run I did when I was alone in the car was about 5 seconds faster IIRC, so we were taking it (relatively) 'easy'. I needed to as I had promised this in order to have a passenger ;)

I will miss the N/A roar tho...:(

Wally September 12th 2008 16:08

Another engine, another possibility to do a track day. Unfortunately there was quite some rain today, but we had fun nevertheless. I took just 1 pic with my digital, but later some more pic/vid's will follow (hopefully).

Hi wally,

I've read your threads on all of the forums and I'm totally taken aback as to how sweet your rides are:shocked:

Nice work! I love your Type 4 Turbo experiments!!

Wally September 14th 2008 04:53

Thanks!

Here's a short clip of the rainy trackday:
Zandvoort trackday

bow September 20th 2008 00:26

i want to know more about the 411/412?

Wally September 21st 2008 14:38

It was my 'safety device' for the day (wife wanted me to tow as I was not allowed to return late that day if anything would go wrong...:o )

http://i174.photobucket.com/albums/w...A.jpg~original

But, what do you want to know? ;)

bow September 22nd 2008 22:50

i love it man that is a sweet pic i love the rims kind looks like your taking the kids to the race track lol

cobra January 21st 2010 11:43

Hi

Where have you bought the wing that you have intercooler in. It looks very good on the car. Have you measured how effective it is with the cooling of the ic:)
