BadAss SRT-Z - 2.4L / A568 - Update!!!

[BadAssPerformance]

I have to say that the fixture helped... but drilling the crank was still somewhat nerveracking! LOL!

[Reeves]

Looks great!

[blk86trbo]

drilling the crank was still somewhat nerveracking! LOL!

Heck I bet it was! Looks great so far JT, I'm really eager to check it out tomorrow

[BadAssPerformance]

Thanks... not sure if it will make it to the meet tomorrow... you're wecome to stop by tho!

[Aries_Turbo]

looks good. how much of a struggle was it to keep the bit cutting the steel of the crank rather than bending and digging into the aluminum?

Brian

[BadAssPerformance]

It dug into the aluminum some, but possibly just from drill alignment angle and vibrating around while drilling. If I were to make the fixture again (or if I need to use ti again) I will drill a smaller than 1/4" hole in it and then on the final pass ream the fixture and crank hole... not sure if thats needed tho as the pin still needed a tap to go in...

[BadAssPerformance]

Forgot the update...

No start Thurday night so I had a ~130+ mile commute home from work last night so stop at a speed shop to get a new MSD non-magnetic trigger. Fired up fine with the new trigger but was too late (noise) to set the timing, so not track today... BUT, I just got the timing all set and other stuff buttoned up and took it around the block a couple times

[2.216VTurbo]

Around the block is a victory in my books! I have like 3 TM's that won't make it that far right now

[cordes]

You've made a ton of progress in a very short time and I'm quite impressed. Can't wait to see it at SDAC again.

[BadAssPerformance]

Thanks guys, yeah, I cant wait to get it out to SDAC too!

Around the block is a victory in my books! I have like 3 TM's that won't make it that far right now

I know the feeling... yesterday was the first time since sometime last year that I was able to drive all 5 cars (3 TM's, Dak & neon) at the house! ... and the other 6 TM's stored elsewhere are far from running, LOL

[BadAssPerformance]

OK, after waaaaay too long, FINALLY an update!

Got it running a couple weeks before SDAC-21 and drove it around the block twice so went to the event with about 1 mile on the new bottom end... yes, for 2011 the Z got a new block/crank/rods/pistons plus an ATI Damper and a new solid hub 6-puck clutch disk with the old PP and flywheel. It seemed to run OK, only issue was a header leak that seemed to seal up when warmer...

Here are the runs

Run #1 - Right off the trailer, 14psi in the tires (higher than normal) cuz I wasn't gonna launch it hard and wanted it to spin a little as to not shock the new stuff... spun hard out of the hole, spun in 2nd made ~20psi

Run #6 - Q-16 Round 2, 30psi ... Pro Tree... Spun in 1st ... This was a FUN race vs. Eric Selof's Shadow (aka B-Slowe Jr. ) He treed me and we were side by side thru the first 1/8 !!! Fun times!

Run #7 - Q-16 Round 3 (Semi's), 30psi ... Pro Tree... Spun in 1st ... This was another FUN race vs. Warren Stramer... Battle of the G-bodies! Warren had a line lock issue when we were both staged and he rolled thru and had to back up and re-stage. I knew I had to make up about a half second so was watching the tree the whole time and as soon as he staged the yellows lit and surprized both of us... I was late but not as late as Warren so got off to a nice hole shot! Looking over my shoulder, I saw Warren coming hard and thought he would blow by me. He was side by side by the 1/8 and stayed there the rest of the way! This was another fun race, great times Warren!

R/T: 1.026 ___ .497

1/4mph: 132.33 ___ 137.02 <== New Best 1/4 MPH

0.0638 difference at the line... damn close!

Run #8 - Q-16 Round 4 (Finals), 30psi ... Pro Tree... Spun in 1st missed a few gears, left too early, no time for JT, LOL! ... Knowing that I would have to make up over a second to beat Slowe, I decided to take a shot at the tree... every pro tree round before went stage-stage-yellows about as fast as you could read that... so as soon as we were both staged, I went and was waaaaaaaaay way RED. Oh well, even if I got a .000 light I didnt have enough for a 9.27@153.34 MPH! Way to go Brian!

So, about 12 miles on the new bottom end and clutch, so both are probably broken in by now, LOL... Next steps:

1 - change oil
2 - inspect plugs
3 - fix exhaust leak(s)
4 - re-tension timing belt / re-zero cam timing
5 - work on suspension / alignment

EDIT: Oh yeah, all runs were lift throttle granny shifting cuz 3 and 4 both sounded crunchy

add to list

6 - work on trans

[Mopar318]

Warrens E/T with that speed shows just how well that car hooks. Automatics help too!

It was cool seeing both cars run at the same time with completely different setups.

[Reeves]

How's the new clutch?

[BadAssPerformance]

How's the new clutch?

It was the same plate and flywheel, only a disk swap... the solid 6-puck disk feels about the same as the sprung hub 6-puck disk... see my edit to my last post, no speed shifting on it yet

[135sohc]

That transmission sure likes giving you grief!! maybe you've finally found the limit of the 523/568 ?

[cordes]

Heresy; Burn the witch!

Great to read that post JT. Glad to hear that you had some good runs with new PBs even though the trans is giving you trouble still.

[turbo2point2]

JT, great job getting the car together and running in time for SDAC! The G-bodies left a great impression on me this year, I need to get my Daytona sorted out and running quicker. It will be good to see the video of you vs. Warren since I wasn't able to see it first hand.

[SebringLX]

Congrats on getting everything up and running in time for SDAC! I wish I could have been there to see it. Can't wait to see your car run again, hopefully sometime this year. I can't imagine how busy you must have been over the last couple months here, between your job, working on the car, and hosting SDAC. Time for a rest now?

[Rampage16V]

Wow JT. Sounds like I missed and awesome time. Damn wish I was there. I'm glad you got some good runs in . Nice when your hard work pays off.

[Reaper1]

PLEASE post a vid of the battle of the G-bodies!! PLEASE!!
