They didn't start the dyno run till 3k.  It was an instant 115tq and 75hp.

Also they stopped at 6k as I did on mine.  105hp vs my 80 at 6k and 90 ft lbs vs my 70 ft lbs.

Well some more Aldon gremlins.  1st one I figured out, but if you look at my boost column you'll see in vacuum advance figures and boost it shows numbers like 255.  When I build up that column it should be -2, -4, -6 and so forth to retard timing under boost.  Load it into the box and after rebooting the car it showed up with the 250 numbers, which would be one hell of an advance curve.  The guy who works at Aldon on this thing is out of the office till next week sometime to answer questions.  So I decided to blow into the vacuum line going to the unit to simulate boost while the car was idling and sure enough it takes out timing.  Why it shows those huge numbers is anyone's guess. 

2nd problem however is an ignition cut sorta speak when i'm cruising at high rpms above 4k.  Doesn't do it driving slow and hasn't done it on any hard pulls up to 6k.  Cruising back and forth to the shop doing 65-75mph above 4k rpms about every 6 miles it will momentarily drop 2k rpms for about 2 seconds, and then back to life again.  Looked over all the wiring and even swapped in another coil just to see if this new 60k volt 1.5ohm monster was faulty.

Plenum I'm going with vs the stock unit.

Turbo air filter has arrived.  The water injection nozzle will tap into the end of it nicely.

Does that plenum have a bell mouth on the inside like a stub stack?

No need for stub stack on a turbo setup.  However plenums require a (can't think of the name) structure by the carb inlet inside the plenum that reduces pressure by a few psi so fuel flow works out properly.

Is that a water cooled turbo, or oil only? If only oil, are you going to add an oil cooler?

I have several if you need one.

Where did you get the metal intake gasket?

Oil only.  I didn't want oil and water. Simple is better.  I might add an oil cooler at some point.  I'm more likely to add an aux radiator.  Gaskets came with the turbo.  I bought an extra set off ebay for cheap too.  Plenum should be in today looks like.

CB Performance black box was back in stock....bought one.  I can use this Aldon on the bus if I decide or vice versa. 

Also had been contemplating a 5 speed.  However the general consensus after doing a fair amount of research, and even reading what Minispares says on their products, I'll make too much torque for the 5th gear overdrive to reliably work.  I may swap my 3.10 gears back in.

Does that only control the ignition?

Yes, it's basically the distributor.

Software included with the black box lol.  Has wiring diagrams and other useful information on the disc.  Loads right up and they have some base maps, designed for vw bugs/busses, but pretty close to what the mini needs and gives me something to work with.  This is a screenshot of a 10psi base map.  Top of the map is vaccum to full boost, rpms down the left side.  Very easy.

Intercooler piping, downpipe pipes for custom fitting, and the water injection kit ordered.  That finishes off the rest of what I needed to buy.  Got the black box installed under the dash but ran out of time yesterday on finishing up the wiring.
