So I went to New Hampshire for the weekend (which is the closest track to me unfortunately...2 hours away) so I could test friday night and race at the import faceoff event

Friday, I was really tight on time due to blowing out one of my tires on the trailor on the way up so I didn't get many passes in.

First pass I ran 11.4 at 136mph with a 2.2 60ft.

I was having trouble with the antilag its set for 4600 rpms but every time i would try to launch it would rev past that then come down to the 2 step. but for the burn out it would always work fine. I don't know why. I figured maybe I might of moved so it didn't engage or something but looking back at the video footage I didn't move at all.

On my second pass this happened and I rolled forward by accident so I didn't even bother making the hit because it was already screwed up.

I was able to make just one more pass after that and I had to let off because the car didn't feel right. I went and checked the logs and I was extremely lean . I think it was due to being low on fuel. I had more gas to put in but the track had closed for the night so I didn't get any more runs in.

On sunday, I went back to the track ready for the import faceoff event. I go to unload the car off the trailor to get the car teched in and all of a sudden the car didn't want to go in gear. ...wtf ....So then once again it became a race against time to try to figure out whats wrong and fix the car in time for qualifying runs. Checked the clutch fluid and it was as full as can be... jacked the car up looked at the slave cylinder while I had a friend press the clutch in and out and noticed it was barely moving. Immediately, started calling local parts stores to see if anyone had a slave cylinder in stock and luckily one did but it was an hour away. My friend ended up picking it up for me but at the point it was too late to enter the class but I could still enter test and tune. I went ahead and replaced it and bled the clutch....go to try to put the car in gear and still can't..... At this point I'm was really stressed an agrivated because we had gone through so much trouble to get the car ready to race and it wasn't going to happen.

I started messing with the rjm pedal adustments and finally the car was able to go in gear. But now the engagement point was off it was very high just didn't feel right to me. I just quit for the day and got the car back on the trailor. I watched a couple of races and went back home very disappointed and frustrated.

I think friday the pedal might have just gotten lose from shifting hard or something. So I'm just going to mess with the adjustment later and see if I can get it right again. .....Just suxs that if the problem really is just the pedal I could have fixed this in minutes early on in the day and could have got some passes but instead I had a miserable time and didn't get to enjoy the event.

Heres, the video of my 11.4 pass sorry for the crappy phone quality

If you listen closely you can hear how the car reved passed where it was suppose to hit 2 step then it comes down.

I probably would have gotten kicked out sunday since I didn't have the license thats required once you pass 135 mph lol

thanks oldman!

Just need some more seat time and some fine tunning. The mph is there. It was a really cold night too was in the 40s. I didn't heat the tires up long enough and I couldn't get the car to hold on the brake on the burn out so I still spun alot but these tires are definitely an improvement. I had them on 15lbs of air . I put them down to 12lbs but didn't get a chance to make a pass on it. I think I need to adjust the boost by gear and add some more boost to 2nd and 3rd too. Right now 2nd is only at 10lbs and 3rd is a lil more. Hoping I can get the car fixed fast so I can go back up next week.

Man that's all part of the game it sucks driving a long ways only to break but youll get it figured out and working right. An 11.4 @ at that mph isn't bad off the trailer. You know there's a lot left in it too. I got mine up and running this weekend with the new clutch. Went for a test drive and it tried to make all the boost haha. Turns out I had a ripped diaphragm in one of my wastegates. Got those fixed this weekend and dialed the boost controller back in and she bad haha. Can't wait to get this thing back to the track this weekend.

theres always something! glad you got it figured out tho can't wait to see how you do !

I gotta look back at my slip but I believe my 1/8th was 7.0 @ low 100's somewhere. Theres so much room for improvement!

I messed with the pedal adjustment and its tolerable for now but idk just isn't the same now. I'm still skeptical that this is the actual issue. As I drive around it will grab at different points all the time. Guna investigate some more later maybe theres something else wrong. Just isn't making sense to me. I raced friday, loaded the car up on the trailer with no problems and didn't touch it until sunday morning when I rolled it off the trailer. I don't get what could have happened from it sitting ....

In the mean time I ended up ordering some things to piece a line lock kit together so I could hold a burn out next time. Can't wait to try that out lol

So after rebuilding my clutch the pedal feel is 100% different. I had the same issue with the Tilton twin disc. The engagement was all over the place you never knew when it was going to grab. I did something a little different this time and I think it's what made the pedal feel a lot smoother and lighter. When I had the trans out I put some moly grease on the throw out bearing slider. Pedal feel is a lot smoother and engagement is more predictable. Not sure if this will help u or if it's worth the struggle of pulling the trans but I know it helped mine out a lot. It's definitely a night and day difference with the same clutch as before.

If I have to pull the tranny out it is what it is ...I'm going to try to do a test launch to see if the clutch slips to see if it got damaged ....i hope not as this thing cost me a pretty penny and its new. how much did it cost you to rebuild yours?

For the pressure plate clutch discs and intermediate plate for the Titlon it was like $450. Not bad at all. I've had it in the car for 2 seasons and it's seen hell so I wasn't mad when it went haha. One thing u want to make sure of is that your not over extending the diaphragm spring on the clutch. I know my Tilton setup came with a pedal stop so it doesn't over engage the fingers. One way to tell if it's over engaging is to push the clutch all the way in if it tries to grab when the pedals on the floor that's not good. You could've bent the fingers or weakened the diaphragm spring if it's over engaging.

I actually came across that problem at the track after I put the new slave in but fixed that after some adjusting. Now it just wants to grab whereever whenever. Sometimes its low and other times its high

I've found the best way to bleed them is to hold the slave shut with a c clamp. I've found it bleeds a lot easier doing that. And then when the pedal is 100% firm all the air is out.

The pedal feels perfect tho its actually the best its ever felt. Just the engagement is off. I'm also using motul 660 high temp fluid since the line is right next to the downpipe. With regular fluid before (when i first got the car out several weeks back) the line got too hot after idling for an hour and couldn't get the car in gear so I had to go with the motul and double wrap the line and then i didn't have a problem again after all this time.

I do know that even before the track when driving around for a while the clutch would start to grab higher and higher the more I drove and then next day it would be low again and again as I drove it would get higher. ....now its just random ....maybe heat is the problem? idk maybe thats affecting where it engages

but at the track the car wasn't hot at all as soon as I started it and rolled off the trailer i couldn't get in gear so I know heat wasn't the problem there.

I was actually standing here at work thinking about this for some reason haha... But the throw out bearing slider hanging up but not stuck necessarily would most certainly cause this. If the slider is hanging up it would require more pedal pressure and pedal movement. Then more rapid movement of the slider once it frees up. And heat would most certainly effect the movement of the slider. It actually perfectly explains why my clutch feels 100% different and is more predictable with greasing that slider. Just my $.02 man hope u get it figured out. Let us know what u find.

so yesterday I took the slave back out and shoved a camera inside to see if the fingers were bent or anything and it seems fine from what I was able to see. I put the slave back in and bled the **** out of it again and still have that weird engagement. It will grab low but not fully disengage untill the very top . Idk I'm just going to do a test launch later and if the clutch doesn't slip I'm going back to the track tonight and sending it!

So the track didnt happen friday.....its been a very sad depressing weekend

Friday after work i did a test pull in third in an effort to see if the clutch was good and make sure logs were good before attempting to go to the track again and i ended up getting 2 codes on

Po011
Po021

went to look at the logs and realized my haltech wideband had **** the bed (third 02 ive killed already)

Went back to the garage and put another wideband in

The codes cleared themselves and about an hour later i went out and did a 2nd gear to third gear with no issues until ..... After the pull as i drove on the highway I started hearing a loud knocking noise but thought it was from a pos van that had driven by me but then my friend who was in the car could hear it as i drove further down the road. It wasnt consistent it was on and off. I immediately exited the highway and shut the car off and rolled to the side of the road.

I left my car there and went to go pick up my trailor as i didnt want to cause any more damage by driving the car. I trailored my car back to the garage. When i had the car running i put my hand on the timing cover and could feel the timing chain slapping inside. So i thought thats what the noise had to be

Saturday morning i got to the garage and i wanted to make sure the car built oil pressure so i cranked it till i saw the gauge go up ..it went to 60psi and then i started it .... No noise ....so then i had high hopes that the motor was fine and all i would have to do is put in new timing chain kit ......

I proceded to drain the oil .... and well all hopes and dreams were lost

I first pulled the drain plug and my heart sank .....found a nice chunk of either rod bearings or main bearings then pulled the oil pan off and it was filled with flakes of bearings





...... So this motor is toast and i dont know the cause, who knows what the air to fuels were like when the wideband was dead .... Maybe it went to lean? Maybe oil starvation ? Maybe when it went lean at the track last week something happened ?...no idea ...

either way the motor had to come out so there was no point to waste time so thats how i spent my weekend ....already pulled it back out and its ready to be taken back to dynosty to assess the damage and get it fixed . i've sent the logs both from the track last week and the pulls friday to Hal for him to look over to see what might of happened

Its really heartbreaking and a shame to have to pull this thing apart 😞
