Got a new best this weekend, went a 9.49 @ 141.16 on a 1.32 60'. I decided to put a slightly larger jet in the dry kit, went from a .51 to a .62. She picked up basically a full mph in the 1/8th, went almost 115, but was down in the 1/4. I think the bottle pressure just dropped too much, so before I go out again, i'm gonna set both bottles up together to try and help her keep the pressure up.

Now onto the bad news (could've been worse). Car was running great and then all the sudden on my third run, I launch, hit second and right after hittin second I hear a loud pop and see a flame under the hood, I immediately lifted, threw to neutral and shut her down. Coasted to the end of the track and pushed her off to the side. My buddy drove over, we pulled the hood off and I was expecting to see a blown up intake, but everything looked perfect, so we started her up and she was idling and running fine, so I cruised back to the trailer and started pullin plugs. All the plugs on the pass side looked good, get to the drivers side and go to pull the first plug and it isn't goin anywhere. So we just start crankin on it to get it out. It basically melted itself into the head. We finally got it out and of course it took the threads with it and the plug was totally demolished! Pulled the other 3 on the drivers side and they looked perfect. So a bunch of buddies from a local board I frequent that I was meetin for the first time helped me get her up on the trailer (thanks for all the help guys!) and I called it a night. Came home this mornin and pulled the head off. Cylinder wall looks good and piston looks good. There was a bunch of **** sittin on the piston, so I did my best to clean it all out of there, but everything should be ok. The head is goin to the machine shop tomorrow to get the thread fixed and first day off after I get it back she'll be back together and hopefully running strong as ever!!!

So i'm happy I got a new best and very happy I didn't have major damage from the plug goin and then the backfire from it. One question though, anyone have any idea what could have caused it, so I can try and avoid it in the future? I mean all the other plugs looked beautiful, just out of nowhere, the one decided to die!

Anyways, sorry about the big *** post, just wanted to post up an update!

PS - I should've known something was gonna go bad last night, first pass I went to make the damn transbrake solenoid stuck, very glad I didn't **** anything up from that, let go of the button and nothin except the nitrous hittin and sprayin while i'm standin still! Got it workin and went right back out and got the 9.49 pass.

 

Lot of work that night out huh! Glad to hear nothing critical was damaged.

 

What does it do when the brake sticks like that Does the car die? I have thought about that, but I have never had a transbrake. I am gettin one as we speak, should be back together next weekend. What kind of brake do you have?

 

No, basically, got on the brake, floored it, let off and my nitrous hit, so it reved higher and I just went nowhere, let off and put it in neutral and she went in reverse so I knew the brake was stuck.

 

Thanks Charlie, and definately a lot of work this weekend!

 

nice runs!
the plug issue sounds like a lean spike. maybe a pos in one of the nossles, maybe a pos in one of the injectors. pull the basket out of that cyleders injector, check that. be sure your lines are clean.
other then that, check to be sure the plug wire and coil are good.

good luck.

 

Thanks Brad, i'll be sure to check all that out, just weird, cuz it was running great all day!

 

all it takes is a split second! one little fart, and boom plug is gone, one little more fart, boom pistion is gone. trhow a sneez in there, and you have a rod threw the block!

 

I almost like to make your quote into a sig

 

go for it. lol
its so true tho!

 

So true!

 

 

Congrates on the new time. Im sorry to here about the problems though. Sounds like it could be a fuel delivery issue. What is done to your fuel system?
Dave

 

donme? you spell like me. lol


i agree tho, sounds like a fart in fuel delievery system

 

LOL,
MY friends that read the board call me all the time to tell me I mispelled something and should use spell check.lol

I tell them no reason to front.. I can not spell... lol
Dave

 

i hear you, i cant spell for **** either, and spell check takes to long

 

Racetronix intank, svo 30 injectors, and a high pressure standalone to feed the wet kit. 93 in main tank, 110 in cell and 20 degrees timing on the tune.

 

your main injectors may be close to the edge! and for cheep insurance, i would run a higer octain in the main tank, and more of a 116 in the stand alone.
try 104 or110 in tank, 117 in stand alone, and bump the timming up 2*.
hello 9.3!!!!!

 

Have you checked the duty cycle on the 150 shot dry?

 

Also you need to make sure you clean out the inside of your intake.Good chance some of the spark plug is in there.
