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

[Stielow]

Jack Ass 2.0



I purchased Jack Ass back from Charley Lillard to give it a freshening up. That car has been on 4 power tours and ran in 2009 OUSCI and finished 3rd. It is a great car and just need a little updating.

Plan:

Swap out the Morrison sub-frame for a Detroit Speed front sub-frame. At the time we did not know how to make the LS9 fit in the DSE sub frame and now I have that sorted out.

Adding Bosch ABS to the Brembo Carbon Ceramic brakes. The car is very hard to drive fast with the grabby Carbon brakes. I’m going to copy the ABS system off Hellfire.

We updated the LS9 last year with CNC ported heads, a bigger cam and smaller pulley. It runs strong but not super strong. So I’m going to get a new 427 short block from Thomson Auto to make another 900ish engine for JA. Kind of a mister potato head engine from parts I have laying around. If we can sort it out it will also be E-85 flex fuel deal.

I’m sold on the DYAD Centerforce clutches so I’m swapping that out and also switching to a Tremec T-56 Magnum transmission to handle the 900ish ft*lbs of torque.

From everything I learned on the Z/28 program and Hellfire I now know how to keep these engines cool and reliable. I have C&R making the latest and greats cooling system for JA. Those guys are great.

We are also going to rewire the whole car to be common with Hellfire. This was the first LS9 we did or for that matter anyone had did and the wiring could use some cleanup. I’m also adding the same on Race Technology dash and data logger as Hellfire. It worked great and I loved having all the data to look at later.

We scaled the car before we tore it down and for a all steel Power Tour car its weight was about where I thought it would be. I think we might lose 50 lbs but that is about it. I'm keeeping it a steel fendered car.



So watch the “Part for Sale” forum because I will be selling most of the take offs from Jack Ass 1.0 and we move to Jack Ass 2.0.

That didn't last long and we are all quite relieved because of it. I tell my wife I'm taking a break after each big project. It never happens, I get bored way to quick.

Always the rabbit out of the hat for you Mark!! LOL

So few people EVER update a build. I've never understood that. Since to me the hobby is about "doing" not being "done". But I also understand taking something that's pretty decent and disabling it. This is going to be great!

I agree to this also. I think about improvements to mine, but I also think that "wow" that was a lot of time and money, and to sell it or scrap some of it is money and time gone. I tell myself to just start with another one.... Probably the wrong way to look at it. Just how I look at it until I get over it. I am not even looking at it as R.O.I. Just how I initially see things.
But now I can sit and watch the evolution of this car, after seeing it the first time.

my car is never done. there is always something to do to one. thats what i like about it. Ive got a 1990 mustang coupe that is DONE(nothing stock of course) and my 03 Z06 which is 100%stock is done and i don't want to open that can of worms on it. The camaro will never be done

Glad to see JA getting some love.

Sweet Mark, That car has been the start for my inspiration for my build.
It's great to see it will be further improved. I can't wait to see the results.

Sounds like a PLAN Mark, Def going to watch this one

What happened to HELLFIRE? CL purchase it???

[fleetus macmullitz]

Could you fire JA up please Mark?

Then the windchill may rise above 0° (for us frozen tundra dwellers).
