Japeatr's knocking at the track rebuild thread
 
8 Attachment(s)
So Lone Star Bash was fun times!

Had traction and shifting lockout issues but managed a 13.73 @ 113.6mph on street tires

Based on trap speed, car should be low 12s with a granny 3rd gear shift

After about a dozen runs on spray and a few without spray, I shut the car down to have some beers while DFWGMElite was cleaning up the event. When I fired it up to put it back on the trailer, the engine had a nasty rod knock.

So I dragged it home on the trailer, pulled VC...nothing out of the ordinary, pulled the oil plu...bingo this huge metal flake was on the magnetic drain plug....FML

Time to rebuild again....

Pulled the block, and removed the head, spun number 3 rod bearing. Ruined the crank and all the bearings. Rods need reconditioning

More NAWZZZZZZ

Wait so the car went 13.7 and blew up? I don't know if I'd have it in me to rebuild after that :lol:

It took me a while to get over the fact that I blew the side of the block open on the yellow car. GLWRebuild, hopefully you have better luck with the bearings this time around. Any over-revs happen while at the event?

JapEatr 06-04-2014 08:36 PM

Regarding the low ETs. I was not there for glory numbers ...lol was more tuning the setup
I was on 225/40/18 KDW2s (my street setup) launching to keep wheel spin in check

My biggest hurdle with the ET was the car did not want to shift into 3rd at 8k.

I had turned the stock flywheel and I think that thickness was causing issues with clutch travel on my GMPP

I had a built motor, just found a weak link in it, rebuild and move on... part of racing

The pauter rods were out of Paul (06BlackG85SS) turbo car. ZZP installed them when they assembled the Girdled block. I think the clearances may not have been perfect


Only bummer is I killed my crank with extended keyway :(

Josh@ottp 06-04-2014 08:54 PM

Match the pistons to the cam and don't go with off the shelf diamonds for the build. You will melt or crack a ring land.

JapEatr 06-04-2014 09:36 PM

I think I'm going with your stage 4s, but I need them degreed that will negate the need for the adj cam gears

Josh@ottp 06-04-2014 09:46 PM

Cam gears are how you degree them. There is no other way.

JapEatr 06-04-2014 10:00 PM

Are Bates and GMPP the only options for cam gears?

Kahless 06-04-2014 10:06 PM

jeff sells crank?

taintedred07 06-04-2014 10:16 PM

Jeff sells everything lol Japs car was a beast on the street even with a 50 shot

lsjion 06-04-2014 10:19 PM

I think you had too much timing in it with the shot.
May consider pulling some next time around.
I'm sure IAT's weren't too friendly either

mrbelvedere 06-04-2014 10:54 PM

Bluelightning 06-04-2014 11:30 PM

Sorry to hear man. What was your ET on spray? Or was the 13.7@113 on spray?

JapEatr 06-04-2014 11:42 PM

Traction, shifter lockout, and poor DA at the track
All my ricer excuses lol

Bluelightning 06-04-2014 11:49 PM

Baaad day at the track and you popped your motor. I'd straight up cry lol. Well sub'd for better luck this time around! :twothumbs

JapEatr 06-04-2014 11:53 PM

I brought it to the track on a trailer pulled by my twin turbo ford truck
So i came to lay it down or break trying

LNFTX 06-05-2014 12:00 AM

Props man awseome attitue about the whole deal cant wait to see what you come up with next I usually end up learning something new when you update your build but sorry to hear it didnt go well this time around

JapEatr 06-05-2014 12:04 AM

Appreciate it man. To be honest the motor had 3300 miles on it, first time to the track with the new setup, raced it a few times on the street to dial in the fuel system

Takes time to work out all the weak links

riceburner 06-05-2014 12:40 AM

Damn dude. Awesome that you are still pressing forward! And its gonna be even nastier this time around! :D

Any footage of the 3300 miles?

JapEatr 06-05-2014 12:47 AM

I have some vids of my nitrous on youtube. Need to get the vids off my camera that is on the car downloaded lolz

Spawne32 06-05-2014 01:28 AM
