All of it looks great.
Beautiful motor.
More pics please?.
Thanks. :cheers: :cheers: :cheers:

OK, here are three more. Everything is now on the engine and looks like it will fit inside the body without external air scoops or body bulges.

What happened to the Burton Brown "special" from page one?

Jack, the Burton streamliner is still a viable race car but will be using a different transmission going forward. Burton tells me he still plans on using an upgraded Stowe 2.0L engine (more hp) but will decide that at a later date. For now, the transaxle  and engine are going in my lakester.

Sorry, without all the injectors in the picture, thought you were using something else. I looked at that at the PRI show (concept anyway) 2014. Sweet.

Any dyno tq/bhp numbers you are willing to share?

 :cheers:

OK, here are the numbers (see attachment). What doesn't show on the dyno sheet are power figures from 7,000 to 8,500 rpm. At 7,000 there is 250 hp, 7,100 272 hp, 7,500 285 hp with 194.6 foot pounds, 8,000 290 hp and 8,500 310 hp. The attached dyno sheet takes it the rest of the way. There is approximately another ten horses left in tuning and another 35 hp with larger valves and bigger cams. Cams in the engine now are considered street cams.

Thanks, looks interesting.     Any reasoning on the manual test?

My understanding is that this is a 198?cc based on a Ford/Cosworth bore spacing architecture.    Is that correct?

With peak power at 9900 rpm calling the cams, "street cams", is perhaps a "stretch", although they might be considered a "soft" race grind by builders with a lot of Cosworth experience.

Anyway, the results are an impressive gain over a Cosworth BDG.    Can't wait for more info.

Yes, the low end is pure Cosworth BDG. The cams are soft racing that by todays standards are street grinds. .450 lift and 300 degrees duration is pretty mild.

Work progresses but at a snails pace. Humidity has been high all week so that makes it worse. But things are getting done. So far, I am pleased with how the car is coming along. No big hurdles so far but like my golf game, there are at least two disastrous holes in 18 lurking out there, waiting to unleash havoc.

The driver cell is nearly complete save fire bottle plumbing, shift and parachute levers and electrical. I hopped in the car last night to see where shift and chute levers should be placed. Happily, there are good locations for these parts.

One question for the group; there is a window on each side created by a forward facing support bar and top of main chassis rail. Once I am belted in, they are well above my hands but will I need to cover these windows or can I leave them open?

If all goes well, the car should look something like this.

If the rear wheels look smallish, that is because they are. This is a one mile to 1 1/2 mile airport track setup. Front tires are 22" diameter while rears are 20.5" diameter. 1" to 1.5" ground clearance.

John, we need to belt you in, with arm restraints, if you can get your hands outside the protective envelope of the cage you will need to add inner panels.

Let me know when I should drop by to get you tucked in there... do you have belts yet?

Fired the motor in the Bockscar, next stop is probably the dyno.

Stainless:

I spoke with Joe Timney yesterday and he is ordering a 7 point harness for me. Not sure when it will arrive but when it does, I will give you a call. In fact, I may have you stop by when you have the time so I can identify where to cut my seat for the lap belt to come through.

Hey, if you are going to the dyno, can I tag along? I love dyno time.

Finding 7-point belts isn't easy, many companies who used to offer them have discontinued 7-point belts. I ordered mine from DJ Safety and was well pleased.

Neil, Joe named the company for the belts but he did say they would likely be custom. Hopefully this will not be too long a process. But I like 7 point if done right.

John,

If you have problems getting the belts, Schroth Racing SFI 16.5 Hybrid III belts are a 6 point that will accept a 7th anti sub strap standard. All of the shelf stuff, had mine in a couple days. Can get either 2" or 3" shoulder and lap belt depending on if using Hans type head restraint. Not the cheapest but nice belts.

Thanks, Andy. If Joe has trouble obtaining a 7 point, I will let him know about Schroth.

Thanks to Stainless for allowing me to use much of how Boxcar is front suspended, my car is now ready for damper valving and springs. Both will have to wait until the car is nearly done but I can at least get a baseline suspension setup with wheels on.
