With the good weather I will say 10.9, with no breakage. Mph,about 127. If you up the N2O, I will second the ringland breakage. Go for broke!

all i know about the truck is it's up in the far north, has a built motor with a turbo and it's a rcsb truck with some crazy suspension.

well........ allmost everyone i know that went to the track broke and so did i. i was hoping if the motor let go it would go out in a glory run with 20psi but it didn't. it died in a pitiful sad way. i was at the track for only a few minutes, just got in the staging lanes and decided to purge my nitrous. i did my usualy purge thru the motor and all was fine but when i let off something wasn't right. it was running odd and died. i thought about it for a few seconds and decided i needed to get out of line and pull over under a light and look things over. i hit the key and it let out a boom. not a big boom, just a nice fart/boom sound. i got some help pushing the truck out of line at that point and then looked under the hood. the nitrous was running . ******* noid stuck open . how often does that happen? the jet was completly frosted over so it had put a lot on nitrous into the motor. it was dumping it in for those few seconds when it wasn't running too. thats what caused it to make that boom sound.

i crossed my fingers. shut off the bottle, unpluged coil packs. turned it over for awhile, let is sit a little, then tried starting it and bang bang bang. something serious wrong in there. kind of a sad way to take out a motor that has put up with soo much .

i was trying the reverse staged nitrous set up. 50shot from 2500-3000 and another 50shot from 2500 to 4000rpm. i was prety excited to try it but never got that far. i am going to send in all 4 noids and have them rebuilt and get a filter. my fill stating has a filter but i dont have one on the kit in the truck. not sure what else to try and have no idea why the noid would stick open.

i took out the other 6.0 with nitrous too. a fuel noid that stuck closed. it was real cold out that day and i had been running xylene thru it so i am going to take the blame for that one but i didn't do anything to cause the problem this time.

as far as damage i am going to say at least a couple of ring lands and at least one rod. it drove it into the garge once i got home and it sound worse than a rod bearing. a lot worse. i will have some pic's of whatever it is in a few days.

Sorry to hear man, that motor was a champ.
How soon until the 408? It sounds like it is about time for it.

sam at cmotorsport told me the short block might be done next week. we haven't even really talked about heads. i might try and get the short block and just slap my stock 6.0 heads on it for now.
