I think you're dealing with perspective with the photography. What appears to be a smaller turbo right behind the engine is actually a similar turbo to the big one mounted on the other side. Photos can sometimes be tricky that way.  :-D :-D :-D

Wide-angle lenses produce a highly distorted perspective. A portrait shot with a wide-angle lens makes the person's nose appear much bigger than it actually is. A 90mm lens produces a true visual perspective.

Neil:

Wide angle lens works like beer goggles? They both produce a highly distorted perspective.

BR;

The closer it is to closing time, the more distorted beer goggles become.  :-D

Is it just me or does that engine look more like a DRCE than an LS? Anybody know?

It's not (never has been) an LS series or a DRCE. The engine is a standard type small block chevy (Dart block) with what is known as a "Splay Valve" head although Dart makes a similar type head called "Little Chief" which is what is being used in this application.

Thanks for that. That also explains why the turbos look so big. Obviously I've never had the chance to personally check the engine out with the body skins off, I'm just always too busy at the salt. For some reason I was under the impression it was LS based.

You're not alone Sid. I had some idea in my head that it was an LS as well.

Here's another half dozen photos of the new Speed Demon's build.













I'll remind you that you can see lots more of the SD II build by going to the Speed Demon site:  www.speeddemon.us.  I just took a very quick look there - and that site might not be up to date.  but what the heck -- they're building a car from the ground up - and hoping to have it ready for SpeedWeek '15.  They've got other than website stuff on their minds. . .  Betty Howard - George's sister -- is sending these photos.  Danny Burrows sneaks into the shop during idle minutes and takes the photos.  Thanks to both of them.

Anyone have good pictures of the front suspension and steering setup.  I have a friend with a new streamliner with the front wheels inline and they are having some issues with suspension etc.

What does the MoTec do to reduce power just before the shift to save the transmission?

I spent a lot of years with Al's tandem front end on Betsy, what's their issue? PM me so we don't hijack this thread.

The MoTec has a gear change ignition cut mode... programmable for cut time or cut while your finger is on the button.  I have mine set for about .090 seconds... it can be set to any amount of time. Since I air shift a bike transmission I have the air solenoid and the cut input on the same wire.  Both actions happen at the same time...
Theirs may be a little more complicated... I don't know if they even need to reduce power for shift... I didn't need to when I had a B&J on the liner.  Of course I wasn't making 2500+ HP  :laugh:
