Just a ? Were you doing these 150+mph runs on the street???

 

someone spilled kool-aid in your engine

 

Oh ya, upon further examination. What's the zip-tie doing in your engine bay?

I agree....that's when my block went. I didn't know until the next day. I just noticed a few smells from the Endyn Breather canister coming inside the car. The next day it shot. %th gear is a lot of stress. The one person I know that had good luck with 5th gear was Steve....MAse. But he tuned his all the time and made it hella fat up top like 11.3-10's. and keept the timing even more conservative. His lasted till it was stolen. So I would blame it on a Timing issue or bad gas, which everyone helse has said. be sure to prevent it next time....

 

blowing motors sucks. the pain lingers on for a long time

 

#3 is always the first to go by design on a honda motor. It looks liek it overheated then detonated and blew the parts all over. if i were you i would serosuly consider goign through the manifolds to ensuer you still dont; have parts of the valves and piston still lodged somepalce before you put them back onto the motor. when a motor blows it sends parts all over.

 

Zip tie is being used to hold the harnesss and everything on lol not just randomly sitting there or anything......

intake manifold.........

 

What about the intake manifold?..........

 

why is it that the #3 cylinder runs the hottest? Was there a reason it was desgined that way?

2 reasons ... its between 2 cylinders and the firing order make # 3 run hotter.

 

So there is nothing to prevent from this one being the hottest then correct?

 

its normal .... their is always a weak link

 

eh, that will buff right out.


BTW if somone allready said that then sorry for the repost.

 

What spark plugs were you running?

 

Pretty sure he's running BKR7E-11's.

 

I would think that number 7 NGKs at 12:1 AFRS for an extended period of time would start to get very hot and possibly cause pre ignition which on pump gas could very easily detonate. It looks as though part of the spark plug went through the valve. do you have a pic of whats left of the spark plug? As antwaine pointed out its a good Idea to run a car quite a bit richer if you know you are going to run extended periods of time in boost. good luck on the new build.

 

stOOpid have a good comments ..... What's left on the spark plug ???? My friend have the same problem with the same cylinder ... It happen's 2 times the first shot He was on maximal boost and the second shot He say a lot of pinkage ???? With no boosting on ???? Maybe de timing was left ???? The timing was I think a part of the problem and the second maybe the spark plug ??? That's what I think...

COUTO

 

Just the tip of the spark plug got melted off.... ill try and get a pic of it..

What I'm wondering is---&gt; does #3 actually get less cooling than the rest, or does it run hotter because it runs slightly leaner than the rest? Does it just have exceptionally good airflow for some reason?

Either way, here are some tricks you can try to slightly improve #3

* if you have balanced and flow tested injectors, put the fattest one on #3

* adjust the valves .001-.002 looser than the rest on #3

* use a spark plug one step colder than the rest on #3

Any other ideas guys?

 

well if its in fact the firing order that causes #3 to run the hottest than to further elaborate, the firing order is 1, 3, 4, 2. if you imagine each cylinder firing and glowing red hot, slightly heating up the adjacent cylinders, then cooling, you'll see #3 gets heated from both #4 and #2 while the others only get heated by the one which fired before it.

 

I don't think the firing order would make any difference. #2 should be just as hot as #3, which is why I was wondering if #3 got less cooling or ran leaner for some reason. I hate to flaunt my ignorance, but does the coolant flow from #1--&gt;#4, or from #4--&gt;#1. It's #1--&gt;#4, from front to back, right? That might explain it then, since #1 and #4 get better cooling because of more wetted area on the ends, and the coolant picks up heat as it passes by #2, so #3 is the hottest. Does this make sense to anyone else, or am I just smokin crack?

 

#3 always runs leaner, both motors ive blown the #3 cylinder has been the one where the action took place
