well finally pulled the head off my blown block.. its been sitting since last weekend of september so thats why u see the rust in the cylinders.. this is what happens in the top of 3rd gear and the internal waste gate just isnt big enuf to handle the exhaust flow.. boost creep, detonation (happened soo fast couldnt really get outta it when i heard it ping), it leaned out to 15:1 a/f.. i expected to see melted pistons, but they're fine.. my datalogging was running, but car is only tuned to 12 psi which was 12.5:1 a/f.. i dont have a boost guage (something thats gonna be on my list to get here soon) and my ECU rom is only setup for stock map sensor so it only goes up to 12 psi.. so i really dont know how far up it boosted before it blew LOL.. oh well, i think my buddy who came with me to the races took it wayyyy harder than me.. i was like ---- happens.. he was like DUUuuuude that suxxxxxxxxx... i just laughed lol..

i've built a new block and getting ready to drop it in the teg today.. dropping my boost down to 9 psi where i originally had it when i was autoX'n and had no problems what-so-ever.. drag strip really did my motor in LOL

anyway, heres the pics
#1 and #3 cylinders cracked.. 2 and 4 are fine (as far as i can see)

Re: carnage pics
 

eeesshhh! How could you run it without a boost guage? Didn't you feel the abnormally hard pull? Really did a number on that one

Re: carnage pics
 

LOL, have always just used my laptop datalogger to watch my boost.. lesson learned.. boost guage coming soon

Re: carnage pics
 

i ran without a boostguage and the wasteagate line connected before in a .60 t3 :-X i believe it bosted 17-20 psi spike, thank god the engine was built.

Re: carnage pics
 

I know what that there is!!!!
It´s bad! O0

Re: carnage pics
 

It never can be said enough but the influx of noobs on hmt stating the mother ------- obvious is ------- annoying.

Re: carnage pics
 

why no boost gauge u so funny
:P

Re: carnage pics
 

Touche´ then... ;D

Re: carnage pics
 

I dont know why in the world you drove it without a gauge..but im not that upset with you cuz feeling that boost prob got you addicted lol

Re: carnage pics
 

DAMN!!!! good luck on the rebuild!

Re: carnage pics
 

who needs cylinder walls? :P

Re: carnage pics
 

in the past i always watched my boost via my laptop, and at 9 psi, it ran perfect i could beat the crap outta the car and still only hit 9 psi.. tonz of datalogging and watching my wbo2 told me i didnt have anything to worry about LOL> then i decided to see what the car would do at 12 psi... at the drag strip.. and though it was tuned to 12 psi, i hadnt done much racing at 12.. so didnt expect what happened.. oh well lesson learned.. getting one of those cyberdyne boost guages with memory ;)

i almost got the new block assembled.. i think i'm gonna have to buy a new oil pan gasket.. kinda screwed up the old one getting it off the block.. gotta love hondabond + oil pan gasket LOL

Re: carnage pics
 

Yeah, because having to look over at your passenger seat everytime you want to see your boost makes sense? :S

Nice carnage

Re: carnage pics
 

LOL i didnt say it made sense lol..

Re: carnage pics
 

Man those are cracks!!! Nice job!

Re: carnage pics
 

Ouch. Lesson learned, use a boost gauge.

Re: carnage pics
 

Screw a boost guage, the more guages you have, the more you tell a person about your setup...

Just make sure you get a bigger map sensor (Motorola 2.5 Bar) and set a boost cut...let the ECU save you.

Nice job on the sleeves Rick :P

Re: carnage pics
 

Sweet carnage. <HT thumbs up> :)

Re: carnage pics
 

i've never seen a block cracked this bad.. i've got a gsr block sitting in my garage.. picked it up from a guy who melted his pistons down boosting 20 psi.. scored up the cylinder but no cracks that i can see.. gonna see if i can bore it out to 82mm and re use the block ;)

Re: carnage pics
 

ouch!!
1 question was your foot still to the floor when it blew?

Re: carnage pics
 

that thing ------- BLEW apart

Never seen one that bad

Re: carnage pics
 

looks like a good candidate to be sent out for sleeves

Re: carnage pics
 

LOL it happened soo fast i couldnt let off

Re: carnage pics
 

yeah might sleeve it one of these days.. right now i got other priorities

Re: carnage pics
 

yea, thats a lot of money to spend. i figure if i am gonna spend $1000 to sleve a block, why not spend $2000 and just get a dart block

Re: carnage pics
 

There is a reason why I implemented boost cut in the honda maps years ago. At the time everyone put their noses up in the air at it but now most people use it. Provided you're tuned to just before the boost cut it will prevent things like this from happening. All it does is activate a 1000 RPM rev limiter if you exceed the set boost level.

Re: carnage pics
 

Because DART blocks are legal at track events...

I'm pretty sure that you cant resleeve a block if it F'd up that bad too. I think once you break both the inner and outer sleeve...the block is only good for melting down.

Re: carnage pics
 

ya you can get a couple bucks out of the local scrap yard lol.

Re: carnage pics
 

that'd make a sick ass paper weight

Re: carnage pics
 

Spend $2000 for a bare block really seams worth it ::) The quality of a OEM block is a lot better then the dart.

Re: carnage pics
 

did you continue to drive it home? :P

Re: carnage pics
 

ouch that about the worst cyl damage ive ever seen on a B without taking the pistons with it too... I overboosted on my accord to about 17psi about 3 times before i realized the wastegate line had a huge hole in it. Yes that was on the stock 135000 motor. Didnt damage a thing, even though it was an ass dyno tune with an safc and 450cc!!

Re: carnage pics
 

LOL i was top of 3rd gear when it blew.. it pinged for a split second, then bogged... could smell the coolant.. my buddy told me he saw a big cloud of white smoke come outta the back.. when it bogged.. it died and never came alive again.. next vehicle down the strip was a fullsize dodge 4x4 dualie and he towed me back to the pits.. i swapped out my drag radials for my street tires.. called my wife and had her come with our Accord.. had my buddy get in my teg and i towed it home with our Accord. its been pushed around since LOL

Re: carnage pics
 

wow, just wow. hey i will probly need to pick your brain about piston choices for the hatch soon and then see when you would be able to come down and hit the dyno to tune it so i can be ready for this year.

Re: carnage pics
 

Jeff, no problem, just remember the head is shaved .040" so you will have to check piston to valve clearance (clay the chambers)

Re: carnage pics
 

Clean it, buy a glass top, and you got yourself a new coffee table for your living room.....and a story to tell your friends when they come to visit.

Re: carnage pics
 

i have an old z6 with a spun bearing i thought about doing that to

Re: carnage pics
 

AWSOME idea :y

i woudl put that ---- in the "Man Den", right next to the kegerator and poker table.

BLOWN MOTOR COFEE TABLE FTW!!!!

Re: carnage pics
 

hmm, i guess the CTR's would have a heavy make out session with the valves if used.

Re: carnage pics
 

I guess bad things happen to people who dont use boost gauges, might want to get on that.
