    Yes, just dyno'd it, it made 925 wheel/780 torque at 28 psi . Yea right......Updates are: Will install the manifold/turbo/motor mount on Saturday. Then mock up the wastegate situation. Still leaning towards dual 38mm tial's set right into the turbine. The manifold is sitting on my desk. My most favorite, although very impractical paper weight ever.

    A pre-mix of those. I'm here, or dare to help out fellow humans. Being serious. I honestly can't wait to see how this beast turns out.

    I'm very jealous of all this e85 stuff going on.

    Hi 5. E85 is really something cool. If it was nla here locally, I would buy it by the 55 gallon container, tune the car for e55-e60, and make it last as long as I could. It's something else.

    I wonder why oem's haven't gotten into flex fuel turbo charging, and raising boost levels on their cars when it's run. If Porsche did a special e85 version of the gt2rs, I wonder what they could do with it. I imagine most of the oem turbo applications are so optimized that raising boost pressure may not be realistic. Porsche's "over boost" function usually nets more torque but no more peak power. Hmmmm, if I were a Oem.....

    Like this? Never could figure out why it didn't catch on.

    If you search BioPower Saab has a newer version thats an electric hybrid, so dont get them confused.

    IMO OEMs approach this wrong. The vehicles should be optimised to run on ethanol (higher compression, turbo) and scaled back if petrol is detected. Designing an engine for petrol and running E85 through it is not very efficient at all.

    They also did patented a variable compression hinged head design motor. When GM purchased them, they shelfed it, saying it was because of costs. I imagine the "only" hurdle on that one is figuring out the head gasket.

    Well, yesterday didn't go as good as I thought it would. 2 soccer games, and the wife wanted to paint the new house mod. Flexer and I took the turbo apart, got the manifold tightened down in the car with two nuts to mock up the turbine, and then figured out how to approach the wastegate design.

    I purchased all the parts for it to complete the new turbo manifold configuration. There isn't enough room to simply mount the dual tial mvs wastegates directly to the turbine. I could see how there would be room to do it just like on Mikes E46M3 kit, but I want to do separates WG's.

    So, I purchase some sch40 1" pipe, two weld ells, 4 out 38mm tial wasge gate flanges, 2 matching vband clamps. Basically, we will tie in the 1" sch40 (about 1.3" O.D.) and then weld on the tial flanges (but using them only as a coupler connection). We will remote the wastegates a foot of so away to the back of the car where there is more room and then from there tie it back into the exhaust. I wish someone made 1" vband flanges. Normally, I would be worried about boost creep with a single 1" pipe, but with duals, its far more than my cast AA cast manifold had. I am really looking forward to the fabrication part of it.

    I don't know what going on with my wife's computer, but it seems to be disconnecting from the internet, and it took like 4 posts to get it this far.

    The story goes on the Batmo wheel is this. There is a local diesel shop here in town (gillette diesel in Bluffdale utah). Guys are really nice, and they always have turbo related stuff, more than any other shop of any kind I have been to here in Utah and they are always very reasonable about gaskets. $3.00 for a divided gasket, and they had it in stock.

    I had no intention of getting a Batmo wheel at this point. The guy that helped me at the counter was obviously more tech savvy than the average Joe, because when I posed the questions point blank with no preparation: "You wouldn't happen to have a Batmo wheel for a 4094 would you" he smiled, and said:" Well, I think I do".

    It was like we both caught ourselves off guard. "well then....How much?". If course, I was expecting $500 since they had it in stock, looking to make some money. $330 he says, and I'll include the gasket.

    Done!!!

    10 minutes before, with no phone call, I headed up there just thinking I was going to come home with a gasket, and then came home with that and some nice billet jewelry.

    From what I understand, these wheels make some nice noise also.

    Awesome!

    The wheels do sounds very nice. My friend just installed one on his 6.0L diesel. Sounds wicked. Plus, he says the butt dyno is reading more torque/thrust down low.
    This is my signature....

    Greg is on the E85 now. Those wastegates are not going to see much flow anyway. Did you take that into consideration when you made that post, or is there something we are not considering. Help us understand your take on it.

    Btw the koenigsegg turns up the power when you have ethanol in the tank from factory.

    Seems odd to use a smaller ID pipe for a larger gate, that was my take on it. That is all.
    Check with Reid Washbon, they might have a 1" Vband.

    Ah roger that. It is going to be a SQUEEZE PLAY to get it all to fit and we really don't need a full 38mm of flow (X2), so this is why Greg went with the 1"

    Wow, great information. Just called them. The have 1.25" which is smaller than anything else I have found. I may go ahead and order that up. The way the OD of the 1" pipe fits on the tial 38mm wastegate outlet flanges works perfectly for butt welding. No need to go any larger than I need, and seriously, the single outlet on the cast manifold was 1.25" at most. Dual 1" far surpasses it especially at the turbine. i would rather not open up the turbine housing any more than needed. I want it to be as ideal as possible when the wastegates are closed as far as the air flow in the turbine.

    Great help!

    Yea there is not much room to play with in there especially for a dual setup. I recommended a split 60 but twins would be optimal.

    Even more weird: Active Autowerke using a 60mm HKS wastegate with only 1.25" feeding it 3 feet away with lots of bends. It would seem if the air makes it through all the restriction up to the wastegate, a 60mm wastegate wouldnt be needed at that point. But go figure, it worked perfectly at 15 psi, no creep. Maybe cast manifolds do better with that, but the design of it wouldn't suggest that IMO.

    Up date here. Things have been really busy with the heat breaking locally and also a booming construction industry locally. Also finished a small house project that was fun. Finally back to spending some time on the coupe.

    I mocked up the turbine housing, and finally received all the parts I need. I received the 1" tubing I thought I needed, but I forgot that tubing is measure in O.D. Not ID. So, I ordered some 1.25" o.d. Piping to match the approximate o.d. of the 1" pipe (which is 1" i.d.). All the pics you see here of pipe are either 1.25" tubing (.065) and sch40 pipe 1". I wanted the 1" sch40 pipe to weld directly to the housing, then will convert quickly after some weld el's to tubing using Marman Clamps (a new name I have learned, knows also as v band clamps).

    The original plan was to use the outlet clamps from tial 38/44 wastegates, but they were still to large for the pipe. It wouldn't have been as clean of a install as I would have wanted. a few pics:




    After searching for what seemed hours, I let off, and came back to google with a fresh mind, and found a company that makes v band flanges and clamps all they way down to 1.00". http://www.detroitflexdefense.com/?page_id=540

    Very nice company to deal with. Here are some pics of their stuff I received (1.25" od clamps and flanges):




    Flexer stopped by, and gave be a nice makita tool to work with that would help be carve out the ports in the turbing housing, but had a thought to google "plasma cutting cast iron". Needless to say, it took about as long to drill a 3/8" hole with the drill press as it did to cut out the holes with the plasma. I must comment on the quality of the casting of the Garrett Turbing housing. Much thinner that I would have thought, and the thickness is so consistent. I am looking forward to the challenge of welding the pipe to the cast iron. If any of you have experience with this, please chime in.






    Wastegate outlets are line of sight from the flange:





    The next step is welding on the starter legs on to the turbine, then cutting up the down pipe and re fitting that to work with the slightly new position of the turbo. Then I can focus on wastegate placement and tying them back down stream into the exhaust. Very pleased that just a few hours of extra time between soccer games and a family stuff I was able to get this done.

    Looking good. I have always been surprised there are few options for an external wastegate right off the turbine housing. Seems to make a lot of sense to reduce packaging size. Makes even more sense on a divided turbine housing.
