Well, you have the DL1 running from the car 12v system right? And you say you need to plug in one more 12v lead to it to read the voltage?
Sounds very strange actually, but then again I never actually bothered with what voltage I have during driving.

[ar4me]

Well, it stems from the fact that if you want to log battery voltage you need the analog-to-digital (AD) conversion. On earlier DL1 the power supply to DL1 was always fed to, and taking up, one of the 8 AD (and logged). With newer DL1 they give the flexibility (since you may want to use that precious 8th AD for something else), and hence you need to provide battery voltage (manually) for logging on one of the 8 AD input pins. I really don't need to log it, but DL1+DASH2 layout considerations again...

Though, some of these parameters are very useful if you experience drivability issues, e.g. fuel pressure for diagnosing fuel starvation in corners, etc. Low battery voltage could cause ECU issues (particularly if you have a mini low-amp 3-cyl Yamaha tractor alternator... ).

Did some cutting this weekend and all of a sudden the Intercooler fits. How about that.

Front view


Inlet needs some additional cutting for the pipe routing


Outlet side is done however, had a big cold-air hose there earlier.


Still waiting for pistons....
Damn americans.

Great pics mate, thanks for sharing!

Is that a strut brace fixing point I see on the last pic to the right?

[Mats]

Indeed it is.
Guess it will need some redesigning now that I'll probably use up some of the space where it's located with the manifold.
Just add it to the list. Guess I'll be on page 6 soon.

Got the rotors today, you know I had to take a comparison pic...



269x22 vs. 315x28.
Weight difference between the rotors, 800 grams...

nice disks
can't wait to hear what improvement it makes.

Hey Mats, welcome to the last second braking queue...!!
Now you are going to have to upgrade your brave pants also to match..

I'd lend you mine but they are full of skids marks already- not too trendy..

[Zamani]

Mats,

Rotors from which car? I'm guessing it's some 5 X 120mm rotors? Some rotors have are thin in the hat area and if you try pressing in the splined studs, you may end up with hairline cracks on the area between the stud holes and hub hole. If you just use the stock Alfa studs, no problems I think.

last second braking isn't a big brake thing, you always need to brake in the last 1/10th of second to be quick. Depending on the equipment, the point which that occurs is located at different distance to the curve though.

Well, I've already thought about it and I will make a backing plate in steel to distribute the load (and to grip the studs), that will also work as a small centering pilot for the rotor on the hub.

The parts are pouring in now.
Runners for my plenum build showed up today, looks like the drawing I got for once. Good supplier, have a treat.





Now for some sim-racing...

[fedezyl]

Nicee, are you planning on joining a band? maybe following the steps of Louis Armstrong?? heheh


Looks very well made, of course, it would be better if I didn't have to force my imagination so much and we could see the plenum design....

[Mats]

The blinds will be lifted when the design is ready.

Mats, looking good(the car). What rim size are you going to use to get over those brembo's. Nice tubular lower control arms.
Cheers
Kevin

They are on a previous page, 9x17 ex STCC rims. Or ex WTCC if that matters, same rim.
