Saw the video before I saw your post here. Excellent work as always! Like you, I was a bit surprised the weight came in that high, and I'm sure you'll add lightness. But you can also just add horsepower!

Ok so catch up time! I guess ill start with the firewall, its made of .024 steel. Everything was sheared out then bead rolled and bent. It makes for very pretty and strong panels. Welding sheet metal to a much thicker tubing is... a difficult process. However it can be made far easier with silicone bronze filler rod. Mig welders i have no advice. It melts like butter and seems to take a whole lot of heat relative to standard steel. And walla:Attached Image

Yeah im suprised but also not suprised. I Dont Know What Im Doing But im trying to. Everything is built a bit heavier than necessary, and less than efficient. I obviously hoped for less but the bed i made is the bed ill lay in. I can make a lot of things very light, and it should still get me in the range where people say: man thats light.

Next up i mounted the intercooler. I chose a mishimoto water to air intercooler, its rated for 500hp which should get the job done perfectly. It’s important to not “over intercool” the engine. It can create more lag, pressure drops etc. But i mounted it using fancy rubber washer/grommet i got from mcmaster carr. The whole unit is very stiff but is still isolated with rubber.

I saw the video. Great work. I’m really not surprised about the weight. That’s a lot of tubing. Still, perfect can be the enemy of good so congrats on getting it built. (IMG:style_emoticons/default/beerchug.gif)

Next up is a simple one, the exhaust. Its only three parts: vband, 3” round tube, and 3” round to oval. I set the length to barely come out of the body to prevent major carbon build up. Tacked it all and back purged it. My tube prep is so good that i can weld the tubes together without any filler rod. The flange will get some but thats to be expected. Next up is the wastegate!

Next is my favorite piece so far! i had to add the wastegate to the collector. This was done in a way to prioritize flow to the wastegate for better boost regulation. This also meant i get to add the screamer pipe to the back end as well.

Then it was on to the intercooler pipe. I have never welded aluminum before, but i sure gave it a good try! i practiced for about 2 hours before finally taking the plunge. I dont have photos of during the process but i can say the design was very simple and i added a tial blow off valve, and i polished the pipe. Overall im very proud of the results.

You're going to love messing with that PMU. I love what they allow you to do... I expect LOTS of details, when you get to the wiring stuff. Keep up the great work. (IMG:style_emoticons/default/smilie_pokal.gif)

Everything is kinda free floating in the last picture, when securely attached everything will be parallel..

Ive done a lot lately but its been little bits everyday until i realized im way further along then the forum. So as a little taste, ive been baffling my small car performance oil pan. I know nothing about this process but now im done so i figured it out i guess. I went from paper template in a diamond shape around the pick up. transferred it to aluminum, grabbed some aluminum piano hinge and slotted holes in the panels. the two were then welded together with a little limiter on it (keeps the doors from closing too slowly) then it was all added to the pan and we have a product im very proud of.

I had a long couple months getting my dodge race ready and nearly finished on the podium, but now im on to the porsche for a bit. Recently i took all the suspension off the car to do some finish welding and make the engine install and firewall install easier. speaking of which; the firewall!
A lot of firewall work has been done to get it ready for wiring and liquid lines. Im using so much filler rod on this stuff but at least it comes out nice.
Also for some reason i get too lazy to post stuff on the car. Call it busy or lazy or something else, but i do get work done on it constantly so progress hasn’t stopped. Attached Image
