Modified roadster construction

Mike,
Those are beautiful headers!!! I agree about header gaskets on turbo motors, when I was at Interscope we never ran gaskets on either our NA or turbo motors, they always blew out. A little red RTV and bolt them on, and we ran some pretty good boost on the V6 Chevys.

Mentally cataloging this.

Rex, you are giving all the secretes away.  Tony

We needed to modify the charge-air cooler which had the inlet in the lower center to put it on the lower left. Here are some photos of the unit cut open and the finished inlet.

Sometime back I posted pictures of the manifold pieces that we had Bob at D & A punch out for us. Here is the basic manifold welded up and just waiting for a bit of port matching & a few mounting holes for the lid.
I went ahead and posted a picture of the current finished part along with what it looked like before assy.

That really looks good.

I wish Bob at D & A would make some parts for our car.  Just kidding looks great.  See you on the salt.  G Man

G man...

Does this swingarm make this Rearend look small?  lol..

... I know... old parts... "Make new parts"  lol

Mike,
As usual beautiful part!!! Your roadster should be taking a "magnum" step up in speed this year..


7800ebs, is that one of Dick Holt's rearends in your car?? Beautiful piece and I like the torque are too.

Rex

[7800ebs]

Yes Sir....

Best Rearend Ever Built...

Please post some more pictures of that car.  Many have not seen it, and it's a treat to look at.  And tell us about your test runs.

[7800ebs]

Would like to but need to finish it..

will be on the salt...



AND don't want to hijack  Mike's Great post on his Roadster...

see you on the Salt..

Mike,
I would be interested in what the top plate looks like for your manifold, I hope it is either thick or has some "crown" to it plus really thick flanges, at 20 lbs of boost there is a lot of force trying to "balloon" your manifold, especially the top plate.

Rex

[7800ebs]

20 lbs... ?

That's ALL...

Thick plate I'm sure... 

try 60 lbs.....  that should balloon it, nicely...   lol


Haas mill standing by with 1" plate if needed..

Update on the modified roadster with a fast approaching Bonneville Speedweek.

First, to answer the question about the thickness of the lid on my intake manifold. It will be 3/16" or 0.187 which ever is thicker.   
If you look at the 2 pictures I posted you will see a couple of fabricated intakes similar to what I'm building. They both run on turbocharged engines. Both of these engines run at Bonneville with over 20 lbs. boost. Both have set many records and both have run over 300 mph. The second one's even run over 400 mph!
From an engineering standpoint the lid should be rounded or bowed, but in the real world that we race in it works fine like this...... for a limited amount of time anyway.
