Tnx Steve, Scott!
It sure went like stink too. Its pretty light and with the 103x71, 44IDF engine it was right on my tail for quite some time. Pity his fuel pump cavitated or s/th as it would not pump fuel after a few laps.
Quite a few people at the track were amazed how fast our bugs went. Priceless :D

And that's why, I bet 90 % of us build these kinda cars... :D
I know I do:lmao:
Chris.

Lookin' good! We need more in car footage :D I love racing in a beetle for the fact that people don't expect it to be quick. I've picked up a couple of stickers for the back of my track car that play on that idea. The first says "Never get stuck behind a vw" and the second says "Pass me with a smile"

You lot haven't been watching Herbie films over the last three decades then???????????!!!!!!!!!!!!!!

That's hollywood, I want the real mccoy!

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.

Michael(aka as Tikimadness):p

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.

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:

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:

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 :)

wicked pic...

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?
