Personally, I prefer the Wacky Racers. I see myself as a Dick Dastardly (or was it Muttley ??)

Hey Wally I found ya!:)
Going to follow the progress from here.

Made a printscreen of a testrun with an aim at 1.0 bar through the range.
Its not perfect yet, but it does show that I now have 'full' boost at 3400 rpm :D
The run was made in 4th gear from 2300 rpm onwards to just over 6k rpm (= appr.120 mph...), still tuning for fuel as this was the first time with an entirely new fuel map a bit changed timing and EBC map as well:

As you can see, air intake temps are a bit higher than last time as well. Temps rose to 37C after a few WOT runs.

Humble June 17th 2009 19:20

Looking pretty clean! Your air temps are a lot cooler than mine since I'm not running water injection at the moment. My temps hit 70-76C at 10psi :eek: and I'm totally jealous over full boost at 3400. Mine barely starts spooling by 3500, no low end for me. Does the software allow you to change graphs like AFR instead of lambda? What's your "water temp" actually measuring?

Yeah, I could reverse lambda an present AFR. Watertemperature is actually the oil temp on the bottom of the head. I only use it for warm-up and it shows usually a little hotter than the temp under in the sump, which I read with a seperate sensor and a gauge (VDO).
I only use a mercedes transmission cooler in the nose and even on the track (high rpm constantly), oil temp didn't rose over 90C, which even surprised me.

Tuning is everything :cool:

Wally June 21st 2009 14:00

At our big national meeting today at Budel I went on the very same mobile rolling road dyno as a month ago and I tuned again for the same 14.7 psi or 1.0 bar boost:

Complete with a bit of flames from the exhaust...:

Thanks for the video Tiki!

Print-out above shows 288 hp at only 5561 rpm and 377 Nm (278 lbs.ft) at 4007 rpm corrected for transmission losses.
At the rear wheel print-out it shows I have 266 RWhp at 6177 rpm which sounds like a more credible rpm.
I need to look at that dip at 4500 rpm, but it may be intentionally as I withdrew some extra timing at what I thought to be the optimum torque point.

Anyhow, the tranny obviously looses very little hp, which is nice to know as well I suppose.
Very happy with the 20 RWHP addition I got with some optimization of some parts and a bit of extra tuning :D

We also had a little drag race today at our local meeting over about 175 meters, which was fun to do as well. Everything stayed in one piece, sun was shining, so all in all I had a fantastic day :)

Wally June 22nd 2009 16:33

Tnx for the nice pic Luuk!
I hope to find some vid's of the drag-race finals as I managed quite a nice burn-out with that run if I say so myself :)

Excuse my ignorance, but what is a NAG? What does the acronym stand for?

Here! As part of Kuleinc signature that I took as part of the post - silly me!

Wally June 23rd 2009 08:34

Ah, I didn't even notice/read it..:o
Actually I dunno either what it stands for; we have to ask Kulein I suppose ;)

On topic :-) , here's two short vids of our 175meter strip...

Attempt to a burn-out, but then without the smoke...:

kuleinc June 23rd 2009 13:06

Its a local car club for aircooled VWs, Norcal Aircooled Group, NAG. They cater to old slow chrome cars, needless to say my car doesn't fit in there. The most important part of their cars are the little stick up plates they bolt to their bumpers, where I'm more concerned with going fast and decent handling. None of them would be caught dead in a 1302 or 1303...

evilC June 24th 2009 04:38

Thanks Kulein. Thurst for knowledge satisfied!

Clive

Wally June 27th 2009 14:31

Our only permanent drag strip in the Netherlands held a street legal shoot-out:

Steve C July 1st 2009 04:36

Hi

It looks like like your car is really getting it teeth into it, nose in the air back hunched down.

How are you finding the G50 ratios? Assuming they are stock.

Steve

Wally July 2nd 2009 17:10

Actually, I like the stock ratios just fine: The longer first is very nice to have with a torquey engine and I drive about 195 km/h at just over 6100 rpm, where my max hp is. In the quarter I don't reach that rpm in 4th .... yet :rolleyes: so I have some room for upgrades left.
Cruising 70mph (120 km/h) in 5th is about 3000 rpm, which is nice as well. Head temp is then 325-350F ;)
yeah, I like this gearbox mucho.

kuleinc July 2nd 2009 17:22

isn't 350 pretty hot, or is that acceptable?

Wally July 3rd 2009 07:54

That range at that speed with those rpm's is not just acceptable, its actually pretty nice.
Stock engines with stock cooling and trannies run 375F at 60 mph when all is well with the mixture in that stock engine...
The nice thing is that the given temps don't rise much at all when speed and load increases. Big difference with a stock engine...
I know these differences very well, as I run CHT sensors on both the 1303 and my daily type 4 with stock engine/cooling.

kuleinc July 3rd 2009 13:33

380 degrees scares me, the next thing I get for my car is a decent CHT, now that I have my oil temps under control with an external cooler.

Clatter July 5th 2009 15:02

380 shouldn't scare you.
425 should...

it does me all the time...:D

cookvw July 6th 2009 01:28

well... ive been waiting to get this answer over on the shoptalk forums. i was wanting to know what normal head temps where on a turbo'd t4, and what was too hott. thanks for the info! hey what head temp gauge you runnin?

Wally July 6th 2009 15:39

I use VDO.

Burn-out at EBI-3 with Dyno Don commenting. Lets just say he didn't see that one comming :D
Spoke him later in the pits: cool guy for sure ;)

Wally July 6th 2009 16:28

Later run:

Humble July 6th 2009 21:14

Lookin' good! You really dig in and take off, it's awesome to watch :) got any in car video?

Wally July 7th 2009 02:50

Thanks, but take off is actually not that good there as I only could manage 2.1 sec. 60ft times on the prepped track. Street tires do NOT like prepped tracks for slicks. Clean raw tarmac is much better for street tires: I did a personal best of 1.894 60ft at the slalom track on the road the same day at EBI, so now I know ;)
Sorry, no in-car video (yet?).

NO_H2O July 7th 2009 08:46

Nice stuff Wally. Looks like it is pulling good once you get hooked up. Keep the videos coming.

Oh, the type 1 engined turbo car lost that race hehe..

Wally July 8th 2009 13:42

This one is still from Drachten streetlegal race two weeks ago. Love this one very much:

Love the Pics :D

Xellex July 9th 2009 06:40

great pics wally! Man, I wish I could have made it to the EBI this year...

Wally July 12th 2009 10:18

Burn-out and run at EBI-3 against the turbo-type 1 at about 6:00 minutes into the video.
The whole vid is worth looking BTW!

kuleinc July 14th 2009 19:03

I don't like the VDO HT gauge at all, I think the delta digital one is much better? It has compensation for the signal wire to the gauge I believe, that the VDO unit lacks...

speedy July 16th 2009 01:51

fab video wally,I hope to get over there in the next couple of years , just in the middle of house moving hell at the moment so the car has taken a back seat , but looks like a cool show all the same

Pa Pa Pa Pa Pa Paaaaaaaaaaaaaaaaaaaaaaaaaa!!!!!!


:lmao:OMG. That dude is so funny! By Sunday, he couldnt do it anymore!!!:lmao:

Got a wicked pic of him and "MR. Flat4" And an autograph of Dyno Don. Only afterwards I was like "You dumb idiot!!! Why didnt you just ask for "Mr. Flat4's" autograph as well!!!???" He was right there and not busy......

Just a shame I didnt pay attention before, otherwise I would've come up to say "Hi" (not that you would've known who I was :D I haven't bee naround as much as I wanted here lately :( )

Hey 'zeroaxe',

It was nice to finally meet you at Spa last sunday! Pity I couldn't make it on saturday because sunday was mostly raining...

I only did one pacecar-following lap on the track. Hopefully with a rool-cage in next year I can do some 'free laps' :D
