Going for tens in the zf. (Mission Accomplished!!!)

[zf>allison]

Nice work!!

I’d like to see a vid of those passes. And an in cab GoPro would be cool too!!

In cabs weren't very exciting with the n20 I shaved 3 tenths with losing the ability to full throttle shift at the same time. Figured out my shiftng issue so should be good now.

Long story, I loaned it to my competition for my sponsor. We both had super stick zf6s. He broke his at ucc so I loaned him mine and sat out of about 4 race days now because he broke mine also. Waiting to get it back, so just doing what I gotta do to make sct.

That sucks man, hope to see you out there making progress on your ET!

If she shifts et should drop easy.:woott:

Got a glow plug delete soaked and alot of white smoke if we lift it up off idle. Just got a scanner and seeing what we can find.

I saw it there with both trans on the ground beside it.

I think he broke the input shaft if I remember correctly?

Yes sir, today we had a bad engine day lol. We think number 7 cylinder is down. Was like that off the trailer but the 300 shot must have done it in. Plus 11 balance rate on that cylinder and a wet glow plug delete.

High crankcase pressure too?

Didn't even check that we just knew we were done lol. We talked about it on the way home, gonna check her out. We will fix what's broke and reuse the rest.

No crank case pressure:woott:

We're gonna check the injector, no fuel in oil at least yet. And do a compression check still.

 

[PureHybrid]

At least the pistons are probably still good. Well, 50/50 shot :roflmao:

Bet it’s a bent rod. Sounds EXACTLY like mine when I bent cyl #5 rod. Your train of thought of it being an injector is what I thought too lol

If it's a rod we got a few spares laying around. Doesn't smoke at idle just around 2k just seems like the issue came out of nowhere not right after or during a run. We will see what happends stock rods are cheap lol

Compression test first. X2 on bent rod. They can bend quite a ways before they break....:hehe:

Wouldn't suprise me, over 30 passes at over 750 hp, at least 10 with spray which 900-1000 rangeish.

 

[NC-smokinlmm]

I'm going to be positive and say it's a bad injector nozel...

yeah once mine warmed up, you would never know other than by balance rate. never knew it till the next morning headed to NHRDA event by my house. that cyl had 250psi of compression and kissed the crank :roflmao:

Yeah I figured once it warmed up it would be good but it wasn't, actually got worse. We might get around to it this weekend as I don't even have my trans back yet. On the other hand the daily has the old dual disc out of the race truck now. So something good came out of swapping the transmissions.
