funny email
I just got an email from the guy I gave my blown engine too:
Hey guy I thought I would drop you a note on the engine you gave me. I found the problem. Each piston had a series of cracks between the grooves and lands( spaces between the ring). I am in the final stages of putting the engine back together. Do know the age of the water pump and timing belt on the engine? Thanks again. |
lol...newb ;)
|
i love stress cracked pistons...
had an uncle that used to race mini-sprints, ran 250cc 2 stroke engines, melted pistons on a monthly basis... ive seen some pretty fucked up pistons.. the best was the one that melted right in the top and when it came apart all that was left was a hollow cylinder with some rings on it, and the center portion was still atatched to the rod... wish i had pics |
I asked him for pics. That only took one 1st test drive and about 5 seconds in boost to create. ;)
|
how long ago did you do this?
|
my ring lands where toast damn 5 sec of detonation shouldnt do that you musta done something way wrong on that one.
|
i have to ask, been wondering a while. what is the reasoning for using cast/forged aluminum for pistons instead of what they make rods out of or somthing? is it the expansion rate or weight or what? seems like pistons are the week link in every engine. a stronger piston gives you soo much more lee way for everything from tuning to revs to longevity.

the day after I first installed the kit and drove it to the exhaust shop. http://memimage.cardomain.net/member...97_14_full.jpg I gave the engine away and never heard back from the guy, always wondered if it was just rings or not (lost compression on #3)....almost a year later he emailed me. |
If I had more time, I'd love to be rebuilding my engine...oh well. Sometime in the future, eh?
|
Thats funny
|
Pretty nice of you to give away an engine, regardless of condition.
|
it was taking up space....and yeah if i was smart i would have kept it and rebuilt it. i've slapped myself a few times for that.
|
no shit, where are the people in my area givin engines away?
|
|
nice
|
whoa.
|
eh, i asked because i read your FAQ and the projects and then i see this thread, made me think "and i'm listening to this guy because?" lol...
would there be anything wrong with driving it to the muffler shop? i'm planning on doing that after i install my turbo (march)... |
again; I was running 87 octane & 14* static timing. I learned things the hard way. I way too excited and overlooked two vital things.
|
how much static timing do these cars like with say 8psi? 0 or retard?

with 93 octane and an IC, I'm retarding to 8* with my Bipes.

I like the inclusion of the cat litter in the picture, right on top of the oil.
|
what about the big box of matches on top of that so we can start a large oil/coolant fire.
|
was that also the day the chro-mo flywheel went in??
|
sure was. and it's soon to be removed.
speaking of...you available sometime in the next 2 weeks to set my backlash? |

I'm not saying it had anything to do with a muffler, but:
87 octane fuel :doh: 14° base timing - No retarding device :doh: 203cc injectors :doh: stock fuel pump (3-4) 6psi pulls from 2nd to 4th The final resulting in a billowing stream of brillant white smoke out the tailpipe and loss of compression in #3. http://www.magnaflowonline.com/images/miata/smoke4.jpg http://www.magnaflowonline.com/images/miata/smoke5.jpg http://www.magnaflowonline.com/images/miata/smoke6.jpg These pics are from my 8th post ever on this board over a year ago. This was my first timing driving in boost, I didn't know what I was getting myself into. Had I known now, I wouldn't have been so stupid. I'm sure the thing was pinging like a motherfucker and I had no clue, and especially couldn't hear over my open DP. ;) |
mine looked exactly the same tried to drive it to a miata guy in louisville but it made so much smoke me and my dad figured id get a ticket so it came home and we yanked the motor. It is sad to see that happen but atleast you know better now.
|
I learn the hard way. I don't use Braineack for my handle and tag myself "The Sadim Touch" for nothing ;)

I dont really need you for two weeks, but in about two weeks I will. ;)
|
dingus. i mean any day is fine as long as on that day I'm home early.
|
i need a motor also, lost lots of compression across the board....
|
i told you to be careful!
|
braineack and i might be able to get you our old pistons :rofl:
