You can get blow by signs if you pop the headgasket in the right place too. I take it there wasn't any coolant/oil mayo looking stuff on the dipstick? Might want to do a compression test too, but that will obviously fail, but curious as to how bad.

 

KR was only 1 or none. AF was on or below 12. It ran great. I think it is those cheap GM pistions because Cam is making around 350HP to the crank. At first I thought it was a head gasket but by the sound of, it seemed like it was firing on 3 cylinders (yes I know it could sound like the with a blown head gasket). Maybe he lost compression in one cylinders is what it seems. We will see.

Yeah no signs of coolant or anything. Then he would be in ****'s creek. It was all oil when we wiped it down to clean it and drive it back home.

 

Yeah, the highest I saw the AFR during the run was like 11.8-11.9. Also through out the run my KR was at zero exept for a few spikes of .8-1 then back to zero. I'm pretty sure I just over powered the pistons. I mean, I had to puttin at least 320 to the wheels to be able to beat a 298 whp SRT that bad. Just a matter of time I guess...

 

That really sucks to hear man, hope you get everything back to its peak performance level again.

 

Won't be for a while, I just made my payment, and my registration is up at the end of the month, $370!!! WTF!?!? So yeah, it will be a while before I get the money together

 

damn that sucks so bad,what are you gonna do for your daily driver?? and i just ordered my 2.6 , i dont know what to do

another thing what was the temperature when it went

 

damn man... just saw the vid... but it def sounds like the 3 other motors that blew up by me... WRX swap...lol.. thats the best way to describe it.. sorry to see it go down like that.... but at least ya won

 

With the other motors, what was the diagnosis? Ringland?

 

2 were broken ring lands.... one had a hole in the piston... all were piston #4 too

 

Yeah, I'm pretty sure its a ringland. I can't imagine why it would "hole" a piston, I wasn't running too lean and I wasn't getting any knock or very very little. **** man, this sucks monkey nuts!

 

hahahah That cly # 4 needs a fuel return line or sumthing to feed it more fuel. It always dies just when the actions getting good....

How much is fixing it looking like

 

put all your stock **** back on and go in for warranty

youll have a ported blower thats the only thing i can see being a problem

 

You "hate GM" because you hit the rev limiter and blew your car up.. your modded car? lol

 

I didn't hit the rev limiter, it was the ring that caused it to pop like that. I hate GM cause they put a strong ass crank and rods, then shitty pistons!

 

Damn, that sucks bad. I guess I will need pistons in my plans for the next year.

 

Do you plan on at least taking the head off and taking a look anytime soon? My car did exactly the same thing as yours (sounded like it hit the limiter, shot oil, cam/wrx sound idle), but once the head was off, my pistons and cylinder walls were pristine. So I wouldn't get ahead of yourself until you actually look. Compression test would also give you a better idea.

 

I don't think a compression test would help anything, the compression would be really low for a blown head gasket, ring land, or a burnt valve. So I think I might just take the head off and have a looksy.

 

the end of the video brings back memories.... its deff ring lands....

 

SRT pwned!!! But you cheated with the motor Suby motor swap.

 

Does anyone know where I can order the Mahle 8.5:1 pistons? I can't find them anywhere!

 

pm djt I think him or self infliction from the rl forums might be able to get their hands on em..

I don't know what happened to the Mahle... they used to be for sale on cobaltperformanceparts... but no longer on the site

 

Yeah, I know. I don't want to get the diamond pistons because they are too high compression for the amount of boost I'll be makin with my twin screw swap.

 

**** I"ll be running the 9.5:1 diamonds with my turbo build.... don't need high boost... just high airflow (I"ll have cnc'd head, cams, and to be determined turbo) should have some more info tomorrow

 

Last I heard the Mahle pistons were not the proper pin size and outer diameter. That is why CPP sent them back.

 

damn dude your top end was insane you just kept pulling like a nerd on an asian **** site. sounded like you had a great time you know I like pickin on you so does this mean that instead of now having one of the fastest cobalts in az you now have the slowest? and all in one night? sucks that happened though git r fixed up and then do the twin screw and pwn again ...
