Are you using a walbro 255? If so I'd be more than willing to bet you were at the limits there of. 10.7 AFR's with that kind of power on stock fuel lines, 255 would be about capped out.

I'm on a walbro 450 with a -6 feed and a -6 return up to the firewall. Then stock return to the tank.
And thanks for the words of encouragement fellas. I've got a lot of work to do but unfortunately with the holidays coming up babyg may need to be pushed to the back burner for a while.
I hear ya there

Bryant, I am using 1000cc RC injectors
Yeah man it's the nature of the beast. You mod cars and you risk this. Look at it as a blessing. That blown motor could have saved your life. Who knows. Somethings are out of your control. I personally believe everything happens for a reason. Some of those reasons we never get to see or understand in our lifetime but there was a purpose. So there might be a reason why you have to put it off until later.
Yeah everything happens for a reason. I'm just trying to stay positive About it you know. I'm pretty sure I can replace just that piston and clean up the cylinder wall with muriatic acid to get the melted aluminum off the top of the cylinder. The cross hatch is still in good condition but I figure I would run a ball hone in it to freshen it up so the new rings in that cylinder break in properly. I have to call wiseco tomorrow and see if a replacement piston is something I can order.
Damn that sucks. Great numbers though, incredible numbers!
Uuufffff well tht sucks cojones..... but like some guys said those numbers.... u know what to expect when u come back. Nice numbers. Push g to the side and enjoy holidays. U will come stronger.
Will you have BabyG for out get together?
Dave, unfortunately I will not. But I will have my stanced Lancer so it will still be an all mitsu outing!
:) Werd.
Got the injectors flow tested, and they all checked out good. I am scratching my head for sure. Ordered a piston and getting the head sent out to get new valves on cylinder 4 and cleaned up, decked, etc.
Only thing that I believe may have happened is that the Piston developed a hairline crack that went unnoticed when the pistons was hitting the bottom of the cylinder head due to the wrong head gasket and at 26psi it broke off and killed the plug. Though this may be far fetched, idk what else would cause this catastrophic damage.
What head gasket are you using??

I was using the Cometic recently but the time before it was the OEM 4g64 headgasket. The OEM gasket caused the tops of the pistons to hit the bottom of the head. I mentioned it a couple pages back from last time.
The cometic is three times the thickness of the stock head gasket so I highly doubt it that the head gasket was the issue.

I WAS SAYING that the pistons may have cracked from before and we didnt see it putting it back together. I didnt say the head gasket was the issue THIS TIME, I was saying the old head gasket that caused the pistons to hit the bottom of the head may have led to the piston cracking and finally broke off at 26 psi of boost. Like I said far fetched but the injectors are good so I am scratching my head here.
U can chill out. I just misread your post. No need for any of this.

Did u check the rod bolts and made sure they didn't come loose which allowed the piston to contact the head??

You would detect knock with that I'm quite positive

The rod bolts were tight. I just pulled the rod and piston out and the rod definitely did not move. Btw I didn't mean to sound defensive I'm just explaining my point.
Jared, unfortunately since I'm not behind the computer during the pulls I only know what I'm told so whether it had detected knock or not I wouldn't known.
I won't hold it against u, we've always been cool. So injectors checked out. How about the injector clip?? Or back to your theory of the piston cracking from the last incident and went undetected.

I've seen that happen on evos pistons and blocks alike.
Looks like knock and heat to me, a byproduct of pushing it too far too early in the tuning process. 26 pounds on the third pull? Sheesh. Pistons don't just melt and your egts would've been crazy with such little timing at high rpm. If you didn't see the damage from the pistons hitting the head the chances of a crack are nonexistent, forged pistons are extremely ductile and unless the damage were visible and tangible they would be fine. That said if you ignored visible damage well then none of those should be a surprise.
I honestly don't know what happened all I know is I gotta fix it and try again.
I'm sure you'll get it all sorted eventually
Little update. Some shitty pics but atleast there are pics. Were getting close. compression test came out good. The front end is starting to get crowded with all the "coolers". New wheels and fatter rubber as well.

Nice progress. Stayed 17x9???
Thanks! Yeah the new set up is a 17x9 +35 up front and +27 effectively in the rear. The tires are 255/40/17. I think I need to run a 10mm spacer and extended lug studs because the front may need some camber and with the tire size right now there is no way it'll clear the coilover
Damn 255!!
Yea i bet. 255. Sticky tires??? Someone not gonna let the road slip... lol
Im kinda torn between the Federal 595 RSR (Good reviews on evom and NASIOC, $40 bucks cheaper than the other tires), Hankook Ventus RS3, and the Dunlop Direzza ZII Star specs. All in 255/40/17
Direzza noooo. they are hard. U will have to run them at low psi. I really dont recommend. Dunlop fuck up on those tires when they replace the dunlop fm901.(i wish dunlop never discounted them). Personal experience. Federal i seen alot on srt4 and subbies.
hmmm... all the people i know who autox and roadrace swear by them. Thats something to think about. Im thinking hard about the Federals because of the price and the good reviews.
The Federals I am thinking about are the 595 RSR not the 595 SS. Two COMPLETELY different tires.
Oh ok. Maybe the compound does well on those tracks. I had them for streets/dragtrack. I guess it all comes down to what u really gonna put the use for.
streets i will do federal. Never played with hankook and dont really care for them.
the hankooks are pretty good with road racers and autoxers as well. which is why im torn. Hankooks are cheaper than the dunlops and the federals are cheaper than the hankooks
Star Specs are FAR from home at the drag strip but at the road course there an awesome tire for intermediate drivers. Not to mention there low cost at around $180 for a 255/40/17 tire is a huge bargain for the road course guys plus there great in the rain and they last a long time. I have around 16 track days last year and Im pretty sure they'll give me another 16 the way they look. I also had a set of used Z1's Star Specs the year before and they lasted me the whole season too,,, great tire in my opinion.
Ive also heard good things about RS-3's but never real heard anyone talk about Federals around the paddock. What ever you get just make sure they do good in the rain because once you get into this level of tire the wet traction gets kinda sketchy even in run around town speeds.
From my experience with the Hankook RS-3's is that they're a good handling tire on the road course with good characteristics during street use. On the drag strip they aren't worth squat. As far as rain goes, I've avoided driving the car in the rain for the 2 years I've had the RS-3's except for one occasion on my way to a weekend at the track where I encountered about 90 minutes of torrential downpour and their performance was "acceptable" but not very exciting.
yea down pours are tuff on any tire but more tricky on a low tread wear tire. It shouldnt be a deal breaker since everyone has different driving habits but for me its a plus if it does have good grip in the rain, I mean at least to an extent cause there eventually gonna lose grip in the wet but the question is at what limit.
sorry jigz don't mean to turn this into a tire thread,,,,,
what oil cooler are you running? Looks good peeking through the fog light cover and Im glad to see you stepped up to a full rad!
Jigz, why not wait for Bridgestone's new RE71?
