These are made from stainless steel except the flanges. 1 5/8 primaries 2.5 bends. I took these pics to send to jet coatings to get the extreme silver treatment on the headers/turbo/wastegate. what do you guys think?

What brand is the valve? Looks interesting. I'll be doing the same thing myself soon. If you took pics as you made them you should post it in the DIY section.
 
its a knock off hks 50mm gate its modified to be adjustable and used antisieze nickel compound on the valve that withstands 2400 degrees :tongue:. Unfortunately i did not take progression pics. wish i had.
 
Those look nice. Theyre almost identical to what we have on Shane's TFS car, which are also 1 5/8th. The big problem with this style header, and this will be irrelevant to you because of your setup, is that you cant get any of the 3.5 downpipes to clear where the crossover joins up. Thats why we scrapped the design.

We're currently building some 1 3/4 headers that I think are going to be the hot ticket.

I wish the demand was there.. I really would like to do a production run of the big tube stuff. I know it works but the masses want someone else to be the first guy to try it and everyone is waiting on everyone else.

More info on the valve please. Have you tried everything yet?:confused:
 
wont 1 3/4 be to much to be pressurized? Im sure you will be using it on a all out race motor like mine, maybe a little spray for spool up. If i had a running motor i would lvoe to try out the 1 3/4 headers. I dont think ill have any problem with the downpipe. Next step is to build the cross over . the cross over will be coated by jet and then header wrapped so it doesnt boil the oil in the pan. I should have enough clearance for a 4 inch downpipe which then run out with an exhaust tip cut out by the passanger door.


Universal 50mm Wastegate + Flanges 10.5 PSI Supra RX7:eBay Motors (item 250442650762 end time Jun-18-09 10:42:57 PDT)
here more info on the waste gate. yes i know i know its chinese but i checked out the internals and the balloon inside is pretty durable. I work at a machine shop. I had a guy mill me out a peice that cups the spring with a internal metric thread to match the top cover and used a allen head cap screw to adjust it. What i also did was replace the flange mounting bolts that is on the unit with larger diameter stainless bolts because the bolts it comes with is to sloppy in the holes. The bolts they have in there are the imitation heat treated bolts that when tightened they strip or crack. The stainless cap screws they use for the cap however are good quality stainless. (suprisingly)


Although in theory this wastegate should work and theres very little info on the net about it, except some bad things and soem guys say they work fine on twin turbo big blocks etc etc. I will however do some considerable amount of heat testing on the nickel antisieze from permatex with the valve and will be posting it on youtube. I will be testing direct and indirect heat testing on the compound to test for its longitivity of lubrication. I will be doing this in cycles. Usually when this type of stuff gets really hot and cools down it dries up and thats a no no :)
 
1 3/4 isnt overkill at all. On a 231 it softens things up a tad but thats what a converter is for ;)
 
Very cool its nice to see someone doing some DIY Fab. and posting the results on the forums.
 
I have been almost 165 MPH with 1-1/2" primary ATR headers. Not sure what the big need is for 1-3/4" primaries at a level below this is at this point. I would like to test some 1-5/8" ones at some point. I am planning on taking some pressure readings at the EGT bung(s) on a couple different cylinders to see what I have and if there is anything to be learned from it.
