Results?

Mark Leasure · 06-27-2015

I got beat by Nate on the first round of eliminations. I figured out that I need to make more boost at the line. It only made 3-4 psi on the 2 step, due to the displacement loss. The goal is to leave at around 15psi, it will make all the difference in the world. The tune is coming along, it went 165mph on a couple of passes. The good news is that the car is 100% and ready for the next event.

Sooo, The Shootout?

Dark2g · 06-27-2015

I'm curious as well. Have you ever had it at the shootout?

Mark Leasure · 09-08-2015

It's going to get real this weekend!

Well it has been a crazy week! Last weekend I went to the Muscle Car Shootout. I wanted to have fun and also get the car ready for the MAP event. My focus was to improve my launch. I knew I needed to make more boost on the line to improve my 60 foot. A special thanks to Nate with the rowdy Civic to light a fire under my ass to get working hard on dialing this thing in. He beat me in eliminations at the last MAP event, and deserved the win! Also, we have a friendly competition to improve our times and performance.
What’s changed since Map 2K15.1? Lots of stuff with the tune, more boost capability, drag style anti-lag, and my seat time to get it all put together!
I lost an elimination round race this last weekend due to a stock front axle breaking. It also took out the output shaft for the rear inside of the transmission. Thanks goes out the John (Pushit 2.0) for helping me out with an extra shaft! A MAJOR shout out to Dan at MAPerformance to help me source a set of 1000hp front DSS axles in time for the 2K15.2 proving grounds weekend!

I have never put power to the ground like this ever! Check this out:

The new axles and 50 psi will make this all crazy town this weekend!!!!!!
Looking forward to seeing you all there!

That sounded messy! lol.

Do you run a certain class at MCSO? I was just thinking I've never seen that event and would like to run in it if I could. (i need slow classes)

Do you foresee any other things getting in your way this upcoming weekend?

Good luck!

Mark is forced to race the Manual transmission class at MCSO. The rules say he needs the car to weigh more to race true street or king street. They changed some of the rules for this year but not enough weight break to race a class to be competitive in. Maybe next year it will be changed so we can both race heads up classes.

170mph..........

Mark Leasure · 09-09-2015

170!

DSMINMN · 09-08-2015

Ohhhh most definitely going to PG now. Can't wait to see what goes down.

C3L1CA · 09-09-2015

That'll be to see this beast run this weekend!

**Halon** · 09-10-2015

Cool, hope to see some of your passes this weekend. I'll be up there running significantly slower times than you, lol.

turbotalon1g · 09-10-2015

In for 170mph time slip

Mark Leasure · 09-19-2015

I had fun at the MAP weekend, unfortunately my car didn't work out as hoped. As for the positives over the weekend, I turned the boost up to 50 psi. The first pass where I drove it off the line with no launch it went 167.49 mph. The addition of 4 psi more boost added 2-3 MPH. I took out 1.5 degrees of timing when I did this to be safe. I had plans on adding a little back in to see if it kept picking up MPH.

Wade completed his license passes, finally! It was an epic rush to get the required passes in on Sunday. He ran 4 passes in about 45mins, requiring a team effort. It was cool to participate and get all the passes in. Pre Celebration:

The bad:

I learned just how critical a good alignment is. I broke rear support tube to the third member differential last week at the muscle car shootout. I welded it back in place, however it effected the rear alignment. I first noticed it at the track when I unloaded the car. Fail! It made the car go all over the track. I needed to drive the shit out of the car to make a pass.

The ugly:

I launched the car on the first pass Saturday, it bogged a little bit, between the 330 and 1/8 mile my drive shaft U joint broke at around 115 MPH. It beat up the under side of my car, and scared the shit out of me! this was the only original joint in the drivetrain! I looked up failure modes, Spicer had a white paper on failure modes. I appears that grease, torque, and application are a contributing factors for burnt/melted cross points.
The plan is to go to the larger 3000GT driveshaft connection to the rear.

It is all correctable and will be better than ever now when it hits the track next time!

That thing was hauling so much ass. Get it back together for the 10-11th at rock falls! Johnnys car might be there if he can keep out of the liquor and get his car buttoned up.

turbotalon1g · 09-19-2015

167? hot damn!!
Getting close man, keep it up!!

b00sted_spyder · 09-19-2015

How about a custom rear section drive shaft? Spicer 2-2-329 flange might work but probably requires drilling new mounting holes for the 3kgt flange bolt pattern. It is a 1310 series joint so it's way stronger than factory dsm u joint. And maybe do a 3" DOM tubing? I haven't figured out the cv head section yet that will bolt up to the driveshaftshop adapter.

**Halon** · 09-19-2015

Bummer to hear man. Saw u a couple times cruising around on your 4 wheeler.

Pushit2.0 · 09-24-2015

Crazy, I need to check mine now.

URV8SUX · 09-25-2015

I got some in car video from PG!

Here is Mark's car when it let broke the U joint, and mine was having fuel issues later to find out clogged injector.

9.5 finger racing..............
