Jackass w/ LS9: original build and new Jackass 2.0 updates!

[Stielow]

It was a busy week at SEMA and OUSCI. I wasn't really planning on doing OUSCI this year but I got a last minute invite and decided to go.

I didn't do that well and that has a lot to do with not practicing all summer. Doing AutoX once a year does not keep your skills up. It also does not help I don't like it....LOL.

Over all I was happy how well my JA 2.0 did.

Below is an overlay of Hellfire best lap and JA 2.0 best lap. JA was 2 seconds a lap faster than Hellfire. I know JA can go faster because my "best" lap was without power steering and a small amount of smoke coming up through the shifter boot. So with power steering and not worrying if the car was going to burst into flames I think it had another 2 seconds in it.

Hellfire Blue Trace



The experiment on cooling is a 100 % success. It was a bit cool on Sunday but the car came off the track with the water at 196 F and the oil at 217 F (I may need to go to a higher thermostat on the oil)

Just JA 2.0 data below



I had a lot of questions on what I'm building next. Right now I'm going to finish my shop. I have been building cars for OUSCI for 7 years now and I need a break.

OUSCI was SEMA cars that can go to the track and now it is Track cars that can go to SEMA. I'm glad the OUSCI has grown and gotten new people in it. But, like I said a few times, a true vintage car will have a tough time against late model vehicles. JA 2.0 is a great (Original Sheet Metal) 69 Camaro that has been on 4 Power Tours and I put 1700 street miles on it this summer. I don't want to gut it and cut it all up to try to outrun an EVO, C-5 Corvette or a GTR. If I want a track car I'll build a track car.

The highest finishing "Muscle" car was Mike Dusold's very cool 67 Camaro. A tube frame, trans axle, Carbon Fiber, Twin Turbo, 2800 lb track car. I met Mike and he is a very cool smart guy. I love the car but I don't want to build or own a car like that right now.

It was great to see everyone and run the car a bit. Now it is time to put our toys away in Michigan and start plans for next year.

Glad you have fun and that JA 2.0 did so well, Mark. Very interesting to see it go faster than Hellfire given all the weight savings you had on Hellfire. Did you think it would be faster than Hellfire?

The BIG change is going from Rivals to Rival S tires. I think JA is making a tick more power but the corner exit speed is up a lot due to more grip and that is where most of the time is.

If you put Rival S on Hellfire it will be faster. Hellfire is lighter, has 315 on the front and has better downforce.

Driving JA 2.0 is like Red Devil with Hellfire's power.

So, yes Charley Hellfire is still better...... If we swapped Hellfire to E-85 it would pick up 6% power.

OUSCI was SEMA cars that can go to the track and now it is Track cars that can go to SEMA.

That perfectly captures what my friend and i talked about all day saturday. This was the 4th time we've been to ousci, and we've seen the move to 'race cars'. You've mentioned you cannot build an old muscle car to beat new cars. Watching that porsche tear up the speed stop in such a seemingly effortless manner drove that home in spades.

Hey Mark, I tried sending you a PM a while back but your inbox was full. Do you have a part number for the Air filter you like to use on your current setup? I saw a recent photo when you were finishing things up on this for the good guys show. It looks like a huge filter, is it sourced from a GM vehicle? I had a discussion with Brian Thomson about this but he wasn't sure about where you're getting the filter from. Thank you for any information you might be able to provide. The Airraid filter I bought was starving my engine on the chassis dyno.

Thanks
