This car just keeps getting better... Good to see that you are making the ABS work.. I am sure it is the way of the future..

I have always liked the GM parking brake.. The other day I was thinking about using it as a standard parking brake on my builds.. Now their is another two reasons to use it for ABS & a floater.. I wish I had your GM resources Mark! Great work..

In a I'm a geeky engineer way, I back calculated road HP at Gingerman. On a 91 degree day we are putting 620 HP to the ground! :thumbsup:

What Ron said! Sometimes you make it look so simple. :thumbsup:

Looking forward to seeing the car again this year at SEMA!

Matt

Once again impressive in every aspect. :thumbsup:

Maybe we'll see the benefits of Mark's engineering and testing in the form of a new Currie crate rear end offering?

That just made me giggle, lol. Hell thats what I put out at the crank.

It is designed to weld to the end of a 3 inch axle tube.

I had 4130 axle shafts made to mate the ZR-1 bearing on one end and a 31 spline Ford 9 inch on the other.

It also has a shoulder for a GM axle seal.

Then I had to make a tool to align it so when you weld it on it sets your camber and toe.

I've been working on this design since SEMA last year when my ABS faulted out. This design fixed the three things that made me mad on my old system.

ABS signal drop outs at high speeds and loads
Brake knock back
Rear axle leaks

It could be a bit over kill but I'm tired of messing with it.

Mark:cheers:

The next level for pro touring
 

Is Kyle going to offer this setup at Detroit speed?

Thank's Mark.:thumbsup: :hail: :hail: :hail: :hail: :hail:

That would certainly address my issues.

I just don't know what to say
 

I could be mistaken, but that appears to have a bunch of design and fab time in it.

Truly spectacular! I can only imagine the machine bill.

Correct me if I'm wrong, but that will not float per-see. Once the axle nut is torqued the axle shaft will become more or less rigid from the bearing into the housing, so very little camber or toe would be allowed. Unless the other end of the axle shaft has a radius to the splines.

I thought "float" referred to whether the hub is retained independantly of the axle. In Mark's case, if the axle breaks, the hub/wheel/tire stay with the car, which is a "full floater". With a stockish 9" arrangement, if the axle breaks, the axle could leave the housing, taking the wheel/hub with it. 9" is a bad example, 10/12 bolt would be a better illustration. The second case would be a "semi-floater".

I'm sure I'm missing something...

Wicked! :thumbsup:

Mark, do you have any plans of doing a car with IRS?

Not in the near future. I have helped do the development work on a couple IRS set ups at work. There is a lot of development to get one to work correctly.

I'm happy on how the DSE 4 link works.

Mark

what happened to you yesterday at the lsfest??

Mark, what Clutch are you running?

I had a meeting at work this morning that I had to be at. It is a 9 hour tow so we left Sunday morning.

Gotta work to pay for this stuff......:thumbsup:

Mark

So how are we going to make this stuff work in a Chevy II?? lol

Looks great Mark!:thumbsup:

Paul

I was running a stock LS9 clutch. I switched to a Lingenfelter LS9 clutch with a higher clamp load. I had an issue with the adjustment and the pick-up point. The clutch was draggingwhen thepeddelwas fully pushed in. Seems like I had air in the system because it was good when I unloaded it last night. Going back though the set up to verify the stack-up.

Mark

Paul

Your Chevy II will be cool when it rolls out again with your new upgrades...:thumbsup:

My paint still look great between all the rock chips....:cheers:

I'll have to get it "tuned - up" after SEMA.

Mark

Thanks Mark for the response,I'm also considering Lingenfelter LS9 Twin Disk or Katech's New LS9R Clutch.Both clutches have 20% more clamping force than a ZR1 unit.Should be plenty enough for a 550+ rwhp N/A LS Motor :thumbsup:

Phillip

Hey Mark sorry about running you off the return road:D lol Good to see you again and as usual the car looks awesome.

Kurt

Mark, How did you abs perform this weekend? I enjoyed watching you run the s*!t out of your car:thumbsup:

Flawless :thumbsup:

My new rear axle set up with the ZR-1 bearings work great.

Mark

Now you can start manufacturing your rear axle set up for us...

Brandon

X2...:hail:

x3! Want it bad!

Hey Mark, are you building a 67 Camaro or are these old photos?
http://www.facebook.com/pages/Sled-A...5063?sk=photos

I think I remember somthing about a car for his girlfriend??? Not sure though it could have been someone else??

That's my car...

Matt at Sled Alley is working on it and it is turning out very nice. The sheet metal work is top notch.

Mark

Ok you can't just pop on in and say thats my car and then your gone!!!:lol: Hum we need details??????????????????????????????????????????? ?????????????????????????????????????????????????? ??????????????????????????????????????????????

Yea know More Power, More Tires, More Brakes and Less Weight.......

I'll post a update later..:thumbsup: Working on getting Red Devil ready for SEAM and OUSCI. It is the '67 in the background being worked on at Sled Alley.

I changed the brakes out to Stop Techs. We rebalanced the caliper pistons in the calipers to better optimized brake balance. The brake feel is great and with a more reliable ABS set up my braking distances are coming down.

I sorted out my clutch issue that I was fighting at Heidts and LSFest. After some research there is a 0.065 restrictor in the clutch hyd. line.

I remember an old article Jeff Smith did and looked it up.

http://www.chevyhiperformance.com/ho...021/index.html

After that modification and a good brake bleed the trans / clutch are working great. It is a mix of OE and modified OE stuff. Working with 800 ft*lbs and trying to road race, drag race and street drive required a little sorting out.

The car ships today for “out West” for Pre-SEMA stuff then it will go straight to SEMA so this weekend was my last chance to tune on Red Devil prior to OUSCI. I think this year’s competition will be very tough. I added a bit more power, retuned the shocks, better ABS and rebalance brakes. I tweaked the areas I could for the event so now will have to wait until Nov. to see how it shakes out. :thumbsup:

Mark

I wish you'd have shipped it earlier --- I'll be in the Napa Valley this weekend -- and I'd have been happy to stop by Charley's, grab the car and put a few laps on it!! hahahahahahahahaha

I'm amazed you haven't bought a car to do these events yet. I think you'd have a ball. :yes:

I have a plan.....

Buy a place in the Napa Valley... and just have Charley bring a spare car to the events so I can drive it. He's good for the gas... entry fees... tires... clean up.

that's a pretty good plan, he'll loan you a car for an event or two. But then he expects you to buy your own, can you believe it?!!! :lol:

Greg,I can fix you up W/a car to run around in.:lol: Now that I have 10 miles on it I am done with it.:lol:

It's not going to Charley's it is going to So-Cal to be used in a Optima Battery commercial that will be filmed at Willow Springs. I'm flying out to drive it next week.

Mark

Greag...Don't be such a tightass...Just talk Stielow into selling it to you. I'll throw in a booster seat.
