Result of boosting w/0 warmup
1 Attachment(s)
Turkey day this year i drove my Miata early in the morning and didn't let it warm up. The next day i opened my hood to find oil blown everywhere from the dipstick and assumed i ruined my rings. Turns out i cracked piston number 1. This was at 264 hp/220 tq powerlevel 1.6l stock with meth.

I feel like it was more than a cold start that did this.
|
Seems like too much timing advance with temperature drop.
|
Was running the same spark tune for over 2 months. The temperature was 40* minimum. Plus I drove that car hard more than once. Surprising the crank and bearings look really good for 130k. I acquired a short block tonight that i will use one of the pistons and rebuild.
Edit to add: What I meant when i said I drove the car, is I ran through the gears all the way home. |
The crank is good for a lot more.
|
I never let my car warm up. I boost down the driveway. ringlands dont blow up from that; let's see the tops of the piston, that was detonation's dirty work.
|
yep. that's det
|
What does the bore look like?
Just gonna slap another stock piston in there with no other work done? |
Come on OP, at least get some egay rods. They will even work with your 1.8 you should eventually build.
|
Bore looks fine. I have forged rods but my plans for this car is rebuild the engine then sell it to get a nb.
