Started the exhaust system. The MaxFlow 4" Hooker muffler I ordered was just to big to fit anywhere. (if anyone wants one of these let me know) I had some new 2.5" glass packs laying around the shop and wedged it up into the 4" downpipe. It quieted down the exhaust a ton. So I decided to go with it. Just welded around the body of the muffler. 
It's a nice quiet tone for sure, but I'm sure it's a huge restriction. I'll end up with some sort of electric cutout or possibly even try out the "WG cutout" idea I had. I figure I could toss a 60mm gate on like so that will open under boost. Hoping between the 2.5" muffler and the cutout it will be able to breath. I could always throw a 3" cutout on it as well. opinions?

If iI need more I'll buy another smaller 38mm gate to put at the first 90* bend.I believe it is just black felt. It was in the car when I bought it.

Decided to go with the 60mm gate... and it was crap out of the box. :yay: Waiting to hear back from seller.
Took a quick video. Made boost for the first time today! Don't think i'll have any issues building boost. This is almost 5lbs and only 3/4 throttle on the brake. Through a 2.5" muffler. Once I get the exhaust dump setup and anti-lag it should spool up pretty instantly. Sounds like a jet!

I'm calling the exhaust done. The new gate they sent me was crap as well. I used parts from the both of them to make one working gate. I wouldn't suggest "godspeed" products. They are pretty much crap. Not that it wasn't expected. I also cut the supplied Wg spring in half and heated it with a torch to weaken it quite a bit. Shouldn't take much boost to open it.
Also installed an exhaust crank case evac kit. It's pulling vac at idle. And gets much stronger in the revs.
Heres the finished product.
Wrapped
Video of the WG actuating with some shop air.
Hard to see but the evac kit is pulling vac at idle.

Also got new window crank assys, glass, door handles And pop rivited some alum door covers on. Now both windows work on this "street car".
Installed some $50 ebay coil overs to raise the front end a couple inches. While I was playing with the suspension I figure I should upgrade the brakes. Ordered a set of drilled and slotted rotors with some HAWK pads.
Wrapped the dump tube and brake lines.
Ordered a cheap ebay oil catch can. Came with no baffles. Was just straight in and out. Installed some brass SOS pads and tubing to help baffle the oil mist. Should work well now. I have the same setup on my other car. Not sure if I will even use it now that I am running an exhaust evac setup. If anyone wants It I'll sell it for $30.

No more 6" cowl for me.
Found a hood on craigslist for $20. Cut a bunch of the webbing out and spent most of Saturday sanding and filling it. Moved some things around and was able to get the stock hood to fit.
Decided to play with this plasti dip stuff everyone is talking about. Still drying here. I hope it smooths out overnight as it drys. Looks streaky now.

I always use BBQ grill paint. Flat or "ultra" black if you want the satin look. I paint the heat wrap with it afterward as well to help shield it from water, oil, etc.
It does grey a bit, but it holds up great. Better than VHT in my experience. Held up for over 2 years on my last turbo manifolds.

Just finished up the headlights and signals today. CF stock hood comes in monday. Then I'll try to tag it and visit the dyno.

CF Hood finally came in. Got rid of the hood pins and installed a factory latch.
Just need to borrow some street legal tires so I can go try to tag this thing...
Made another HVAC cold air intake too. I found you can pull the segments apart and add to them for one longer seamless piece. This also let me eliminate the “crinkled” end pieces. There’s even a rolled bead on the end for your couplers. Made 4 of these so far and they are all holding up great.
This one is hidden in the fender so I didn’t spend any time sanding it or trying to make it look pretty.
If you want it to look more professional you could try just enforcing the ends with glass/resin. Then dipping the whole assy in polyurethane. I think that would turn out slick.

Finally got to a test N Tune. Drove to and from the track. Started the night out running 11's. Got 7 passes in. After a bit of tuning the last pass was a 9.83 @ 143.
17lbs of boost 16* timing. Logs show I Shifted at 5400 rpm and went through the traps right around 5400 rpm as well. Wussy 5lb launch. Tons of room for improvement all around.
Finally got a single digit slip!
Also put some tint on the car this weekend. Can't see the fuel cell or cage now. Hoping with some street tires it will almost look like a street car.

Make that 9.66 @144.6
18.5lbs. 15* timing Started dropping speed at 19.5lbs, I think my super quiet exhaust may be killing me. May make a quick 4" DD with no muffler and give it a go. The timing dropping so low may be killing me as well. Only got 3 runs in.
It's so quiet it almost sounds like the dump isn't opening.
