:secret: Target weight? :)

No details yet. Just I'm going to build a track car next... Someday.

I have not purchased a car yet. :topic:

It appears that if you want to win OUSCI in the future you will need a borderline race car that has lights.

I like events like the Motorstate challenge so JA2.0 will run in events like that.

Mark

I got just the car for you Mark!! This with about 900HP LS motor.... all in all done under 30 grand. Charley waiting in the wings for it. WTF is not to like?!?!? LOL

Is it just me missing a link, or something, or do you need good Ron to setup your computer too?

Mark, as always, thanks for sharing. It has been fun watching the evolution of your builds. I'm always shooting to build something as streetable and reliable.

Hope to get to see it in person sometime this summer Mark. Looks good so far.

Of course, the old rattly JA1.0 would have been neat to check out in person as well I'm sure.

Funny, I just started gathering parts to build one. Wanted to do wing and splitter to help aero, but that may be out the window per USCA rules. Not quite doing 900HP, but thinking 500 ish.

Of course you rich old guys would be at the game.

Mark,

Are you using the Bosch Motorsports ABS system?

Andrew

And have been dying to use picture to let you know they we're .....

Lol!!

Lead.

Andrew

Yes I'm using the Bosch M4 racing ABS system. Works great and has a laptop interface. It is not inexpensive but it does work very well. With the carbon ceramic brakes on Hellfire the ABS system performed flawlessly. The brake feel was as good as a Z/28 (2014).

Mark

Parts for sale.
 

Hey Mark, great build as always.
I've been following your builds since The Mule, they just keep getting better and better.
Do you still have any of the parts that you removed from the car?
I've been watching the for sale section but I haven't seen anything posted.
PM me and let me know what you have left if any.

Thanks.

Keith Quinn.

Awesome as always, Mark!

Unfortunately as it has garnered more exposure this seems to be the trend and I don't know if that's a good or bad thing. It has definitely made certain decisions about my Firebird's build direction a lot easier...

There is this if still available... Stielow Garage Sale II Link

Garage Sale I was a fire sale. Mark really helped out the Lat G community with the take-offs from JA posting on 1/09/15.

For sale.
 

Thanks for the link, looks like everything is gone.
Oh well, next time.
Keith.

Mark, may I ask how the ABS system will help the brake feel? I'm using the ZR1 brakes on my build as well but wasn't aware they would be grabby, is that just the nature of carbon brakes?

They are fine without abs for street driving but on the track under hard braking the grip will really ramp up during a hard decel. At Motorstates challenge I locked them up and slid thru the grass. Same turn they started to lock up on Stielow but he was smart enough to take his foot off the pedal. For track use without abs I was going to swap in steel rotors so I wouldn't have the lockup issue.

Today's update.

Mark if you get a chance it would be nice to see a little detail on the trans cross-member. That really frees up space for the exhaust. How the tabs tie into the doublers on the inside of the floor would be nice.

Thanks

Scott

Did Charlie mention anything about the sharks at the beach to you and Gordon?? Just sayin'......

Kinda like this???

http://i1158.photobucket.com/albums/...09GMSO_122.jpg

Sharks?? Nobody said anything about sharks!! :_paranoid

Great pic of the Jackass driving Jackass, Gordon!! I remember him telling us this story at a track event one weekend....

You guys will have a great time drinking Charley's beer. Post up pics of Liz on the beach... LOL

You need a Camaro imagine how complete you would be. I think your missing that edge Greg. Prolly 2nd gen more your overal size :underchair:

I have been working with Paul at C&R and they have helped me design the new radiator and heat. They are the new Denso high efficient cores with a new Spal 850 W fan. I learned a lot from Z/28 program and Hellfire.

C&R nested the coolers for the best performance. The new cores and thinner and the oil coolers are a lighter.

The oil cooler and the power steering cooler is on the drivers side and the trans / diff cooler is on the pass side.

We should have the parts next week. I love working with the C&R guys.

A cool engine is a happy engine....

It's nice to have a company like C&R that willing to embrace innovation and not just tell you "sorry, just what's on the menu pal".

Mark,

Do you have more information on this new Spal 850 W fan?

Andrew

Thanks for the info, Charlie, and thanks for the visual, Gordon!
Is it still on the original set of rotors and pads?

Yes it still has the pads and rotors it was built with in 2008. The Carbon Brakes wear great when you’re not always beating the crap out of them. So far I have used up half the pads on Hellfire. But that car has had around 3 hours of very hard track miles. On the Z/28 we can go 5 tank fulls of fuel on track before we need pads. (We test tank of fuel at work fill the tank and go flat out until it is empty - about 42 minutes in a Z/28) The rotors will last for about 30 pads changes.

On Hellfire I used the Corvette ZR-1 brake booster and master. There is a Bosch booster is tuned for the ZR-1 (Look it up in Service Parts). I like the brake feel of the OE booster and master. I have also failed many aftermarket booster.

The Carbon Brakes will work fine without ABS. They work a lot better with ABS. I have the Bosch ABS system and I know of a Conti and Dephi system that will work also. The Bosch system is their motorsports system and is very expensive, but gives you a laptop interface and works flawlessly with the Brembo CCM brakes. The Conti race system is available but still not adjustable (One guy had it at the OUSCI this year). The Dephi system is very limited and not commercially available.

Because the Bosch system is designed for racing I never had a drop out on Hellfire. Once it was working it worked. I'm so confident in the Bosch sytem that on JA2.0 I plan on running it and not installing a prop valve as a fail safe. On my other cars I set the base brakes with a prop valve then turned on the ABS. I don't feel I need to do that.

Mark

Thanks for the input, Mark. The only really trick stuff that will be on my car will be the ZR1 brake system so I was a little worried when I read about the grabbing at speed. Mine will be a 99.999% street car so I think I'll skip the Bosch ABS (the cost of the ZR1 brakes was already sobering), at least for now.
Thanks for the input on the master cylinder/booster too, I have the standard J56 booster but will be ordering the J57 piece today.
You've been an enormous source of proven information and it is much appreciated!!!

Hey Murco, what are the parts numbers for the boosters. I like to keep them in my data base for future reference.

Thanks!!

Always try to get the AC Delco part number it is usually a lot cheaper

ACDelco 178-0814 GM Original Equipment Power Brake Booster Assembly

I use Amazon (Prime) so free shipping! (2 day)

Mark

He meant Amazon Prime...Best thing ever..:trophy-1302:

Prime also has no minimum order.

Amazon ships me more car parts than Summit. :ups:

Mark

Shill.....

thanks mark,

118 savings, not bad....and you run the DSE bracket too right?

[Moving info to brake section, don't want to derail thread]

I'm glad I ordered mine before you caused a run on that part number, sold out at Amazon!

A couple updates.

Matt is knocking it out.

The ECM and fuse block mounts where the battery used to be.

Matt suggested we make the tow hooks / tie down out of stainless steel so when the car is shipped the paint does not get chipped off. Cool idea and part

The MIL Spec connector holes are in.

The front inner fenders are re-worked for the down bars.

We have the wiring cart ready for this weekends wiring.

Mark

Looks good! That transmission mount is a really nice piece. :thumbsup:
