The intercooler from turboboxer is a good contruction, but just as Wally pointed out it's not placed very well.Due to its construction though there's no other option really.It's missing a duct system where fresh air can pass through.The current set up in that position is subjected to heatsoak.There are electric fans also,however I don't believe they are very effective, because again, no or little fresh air is present in the engine bay.

I understand I just like the normal hood. You cannot tell if its a turbo or not. I thought that the vents on the bodywork are enough for the intercooler. My bad!!

OTOH, Armin drives it everywhere, also on the track, hard! His combo obviously works well too.
If you like the stock looking appearence above everything else, that surely is the way to go. He runs waterinjection as well, so...
I just _think_ outboard works a little better still. I have no hard data to prove either, so take it for what its worth.

Armin's car and mine usually are the only two type 4 turbo cars that run on the track at full pace, so whatever your preference, just build it as there are still very few beetles running an aircooled turbo'd boxer of either type on the circuits at all...:(

True Wally, however he doesn't have the performance you have,spool up is later (I presume,I've only ridden is his car.I rode in yours with the 1200 installed and comparing the dyno graphs).His set up works, but I am willing to bet not as well as yours.A comparison of intake temps would be interesting.

Hopefully not for long! I'm working to have mine done next summer!

That would be great man!

Thanks Wally, IŽm not missing too much.A good trans+clutch,header (looks to be a modified python),tires and a lot of small items.WeŽll see how much money I can sneak past the wife ;) Next summer is my goal - I hope I can make it!

TSAF June 26th 2012 06:44

That would be great a 3rd type 4 turbo in Europe's circuits!!!!

First pic available from last NS Trackday. Hope I can get it in a little better quality and a few more from her.

Wally,
How's the car now with the smaller wheels and sticky tyres?

Worked awesome! The tires haven't even slipped once, not a tiny bit of understeer. I could have gone faster, but was a bit carefull there as you might understand.
It feels nimbler with the smaller wheels, but that might have been the now more responsive engine as well.
Did the synchronisation today as I still hadn't even done that since it was running for the first time last week (just by ear). It does rev great now!

Some testing at 23-24 psi showed the limit of the straight acn's pushrods for me now:

F...ck, I am at the office and I cannot pump up the volume on youtube:angry::angry:

Wally July 2nd 2012 05:44

Well, tbh, the sound was much better IRL then on the vid afterwards... so your not missing that much ;)

Here you go mate, but be warned as I think all of these dyno movies start looking the same by now...this one is even particularly uneventfull..:

Had some great 1/8 mi practice runs yesterday at a car event, but with official timing by the Dutch Hot Rod Association (DHRA), a subsidary of the NHRA ;)
Best was a 7.57 but with only a 60ft of 1.92 and I had to lift as the car went almost into the gates at 3/4 of the run...

The "burn-out" where they put me on the dry spot with one wheel (that didn;t help keeping the car straight..) :angry:

and two other runs:
