It doesn't mean I'm not in awe of the work...because I am...and I can't wait to see how this turns out!
Hehe...I am just the average guy...I just happen to work with these tools

Intercooler came in...not to big, not to small, just perfect for my goals without sacrificing spool...

Hehe...I don't think it would work for your application, it probably won't spin fast enough. I made it bigger to reduce the speed of the Alternator because I will be running it off a bigger pulley on the crank.

Its also only 4 ribs instead of the usual 5 because it will run off the front pulley which only has 4...

Oh well!

Decided to polish the face of the rotor on the pulley...the pics don't do it justice, had to put a pen in the picture for it to be noticed but it looks like a mirror in person. Has great contrast with the rest of the machined surfaces...

I finally got around to making the two holes for the Wastegates and tacking them on to check fitment. Now I need to verify everything fits in the engine bay and then pull everything out and finish welding the down pipe and the wastegate flanges.

Cheers!

Threw everything back in the car to check for wastegate and downpipe fitment and found that the wastegates were fine but the downpipe would be a bit of a problem. Essentially, I got it in there but it would be so close to everything that it would be nothing to but headaches and vibrating noises so I made marks in the problem areas and I pulled the DP off and "compressed" some of the areas in my big vise. The result is at least 1/2" of clearance everywhere and not so much loss in flow

In the process I also noticed that moving the alternator forward to use the front pulley while keeping in its general oem location would cause the front belt to interfere with the waterpump pulley...this means I will probably have to throw the alternator over to the driver's side (as in the last picture) regardless of my desire to keep it in the middle of the engine.

Cheers!

Worked on the wastegate Dump today...I still want to recirculate it back into the exhaust but for now will just dump it mid way. I am unsure if I will be able to package a reroute into the exhaust somewhere so this will work for now. I would like to add that that flex pipe, which is a necessary evil with this setup, is the hardest thing I have ever had to weld...it just wanted to melt away so the welds aren't pretty at all...Im just happy it sealed...lol I couldn't use a regular flexible section due to the available space.

Cheers!
