Ruh roh...Blown Piston Ring w/ pics (56k=death)

[CobaltSSTuner]

**Updated pics and stuff on pg 3

_____________________
We tore apart the cobalt this weekend. Took the head off, and inspected the pistons. The sleeves are in the best shape I could ask for, for blowing a ring. Doesn't look like there is any major machining needed. Just some basic stuff. I figured I cracked a piston, but this is awesome news for me. Car should be back up and running in the next few weeks.

Here are a few photos

On an even better note, i had a box of parts come to my house on sat :D

As soon as I get the motor squared away, thats stuff is going on^^ :headbang

Just curious, does anybody know what kind of injectors these are for? They came with the turbo stuff...

I want to give a special thanks to Alex(TeamRevSupport), Tyler(Stealthy1SS), and Eric (Ebristol).

[juicedimpss]

dont forget to pull some more timing out.

[GTSLOW]

Man you just had that things at Gus's sat night. Good luck on the new build. Was it a turbo before?

[CobaltSSTuner]

nope, its supercharged. I"m doing a custom turbo swap. s20g turbo.

[GTSLOW]

Sweet man. I'll still take ya tho. :goof ;)

[Flicktitty]

Goood stuff Jordan, can't wait too see it out.

that snail's been needing to go on for YEARS now.

[CobaltSSTuner]

Sweet man. I'll still take ya tho

eh idk about that lol....

I'm shooting for around 325hp on 15psi. Once I get the basic tuning squared away with the turbo, I want to see atleast 20psi.

geez man long time no talk. And its been a Year lol.

My guess is turbo will be on before the end of may :)

No that was me at Gus's. I had just come from his house straight to Gus's. My shit actually runs! :D

The heavy black coating on top of the pistons apears to
be oil from the PVC system, oil and combustion equal
detonation, lead to broken pistons/rings.

Consider installing an exhaust check valve in the downpipe
while the car is down, plumb your VC to this so all the tiny
droplets of oil go out the tailpipe and not into the combustion
chamber. Ive built systems using generic
exhaust check valves from AIR systems on Ford and
Chevys, so well I've had to tweek them from pulling
raw oil right off the pan :o

Another benefit to a crankase evac to the exhaust is it help
seal the rings even under boost, less gas in the crank area
equals more HP and a better running car.

Here is one I made for something, typical downpipe:

alot of his issues have to do with the person who first tuned the car i wont name any names.."cough street attack zach cough huge doucher cough"

Thats a great idea! I'm going to have to look into doing that.

[srt4eh]

I have a Hahn S20G on my srt4 now...wanna run 20Gs at GLD when yours is done? Mine will be tuned by the end of June ;)

[CobaltSSTuner]

hell yea, I'm down. How much boost are you planning on running on ur s20g?

[GTSLOW]

No that was me at Gus's. I had just come from his house straight to Gus's. My shit actually runs! :D

:rolf shit there's to many of you in here.

[srt4eh]

I'm looking at 24-26psi....

lol...its not a race car til I have some headwork and cams...lol. I do have meth/water injection now....this "neon" is gonna be sweet :banana1:

[1siksrt]

hell yea, I'm down. How much boost are you planning on running on ur s20g?

That sucks that the cobalt bottom end is that weak, I put down 450whp without breakin a sweat on the stock nsrt engine...when you get yours done ill take a lane as well:thumbsup sometime in may or june???

[1siksrt]

the cobalt bottom end is actually very impressive its just the pistons are the weakest part. that and bad tuners.

[spindler27]

alot of his issues have to do with the person who first tuned the car i wont name any names.."cough street attack zach cough huge doucher cough"

i've heard a lot of shit about this tool, not one thing was good either, im just praying that the number of srt's he's worked on doesn't increase any further, i have my site that draws just about all of them in, but 1 in particular has gone to him and i'm not very impressed with his work

yeah he likes to blow up cobalt's.:rolleyes: " 4 of them so far plus a possible redline" id advise anybody who has had a tune or work done by him to go in and get it looked at by a professional shop its only a matter of time before it blows

Long time no talk!

The bottom end is somewhat impressive. I'm getting the rods cryo treated for extra comfort, forged pistons, possible neutral balance shafts, but thats really it. I'm looking for a stock set of cams so I can send them out and get them re-ground to 272's and do valves and springs. Then I'll be happy :)

I guess I might just kick the boost up to 20 just because all these srt guys are intimidating me lol :headbang

Yep, zack is a tool. He's been running from me for a while now. Has been nowhere to be found. F***ed over alot of people.

lol...nothing like friendly competition :banana

[CobaltSSTuner]

I'm all about competition. but for some reason, i'm not suprised that 3 srt4 guys find their way in my rebuild thread lol

[boostin350z]

I'm looking at 24-26psi....


good lord. joel is an srt4 god lol, and your turbo is pretty nice. what kinda numbers you lookin at?

[srt4eh]

hoping to hit 400whp...I'll prolly end up just short due to me using the stock head. June 15 its getting dyno-tuned...we shall see :)

Most people I know use a slashcut. If you research that (isn't easy), you'll find you practically don't need a check valve. As the exhaust passes, it creates a vacuum as the air moves around it - not unlike a wing makes lift. Unless you have a very restrictive muffler or exhaust, you'll always get vacuum from it - increasing with exhaust flow. The tests I've seen show ~1-8 inHg at any given load/rpm.

BTW what sort of turbo is that? Looks rather unusual - a bit wasteful with aluminum I might add.

if a certain srt4 i know can run 10's on a stock head @ high 130's pretty sure a stock head and cams wont hurt you that much:thumbsup

ok sounds good, i'll run my pump tune against you.. thats around 20psi..:D

AND ZACK IS A POS, and his work is god awful!!!!!!!!!

well...as far as the 20g is concerned....supposedly the head causes issues with power past 400...i know its got more in it...lol

i'll be happy with stock srt power to the ground... 215-220'ish... :alcoholic

do i get a head start? lol...

[Brian98GTP]

BTW.... those injectors look like stock 36lb/hr 97-03 GTP injectors.

[stealthy1ss]

When is this car going to run again? Next year? Never?

[CobaltSSTuner]

STFU Tyler! As soon as Alex gets some free time, i'll be ready. I have all the parts sitting in my garage.


BTW.... those injectors look like stock 36lb/hr 97-03 GTP injectors.

Thanks for the heads up! i did a lil searching and thats what I came up with...

Sooo if anybody wants some free injectors, let me know.

[Plum Crazy]

hey tuna, my Palmen Hrs are Mon, Tues, Fri, Sat. so, towards the end of June, if you can take a wed and thurs. off, we can pull the motor, get the pistons in and hopefully have it running in those 2 days.

[SlowMotion]

Brian when I saw the pic of the injectors they looked damn familiar definitely gm 3800 series II injectors :thumbsup

[Deggy]

Hey Jordan, if you ever get a hold of Zach, tell him I'd like my $100 muffler back or my $100 back.

Well I need to give atleast 3 weeks notice for vacation. So the soonest I could take off is the 17th&18th. Would that work for you?


Hey Jordan, if you ever get a hold of Zach, tell him I'd like my $100 muffler back or my $100 back.

deggy, there is no way zach is going to talk to me...i'm out for blood...and he knows it. He screwed me over hard, and lots of other people. I've tried calling, i've even tried tracking him down. Bastard keeps avoiding me. Now i think he's in the navy, but idk. If i ever see him again, it will not be pretty.

[srt4eh]

those treadstone fmic are supposed to be pretty nice. Whatcha doin with the other one?

[CobaltSSTuner]

prolly gonna sell it. It was too small for my application too, so if anything, i'm just gonna see if i can sell it for like 50 bucks.

[SpdRcrZ]

this thing running yet? lol


Damn I miss my Cavi now!

[That_Guy]

its top secret grasshopper

I thought you had this bad boy almost done already. looks like I will have my toy rolling before you then. :wow

[That_Guy]

I thought you had this bad boy almost done already. looks like I will have my toy rolling before you then. :wow

his car was finished this last weekend and tuned

[CobaltSSTuner]

cars together, working on a few small things. its been hard to find time to work on it. takes time. im basically ready for tuning

[srt4eh]

My car needs tuning as well....would have been tuned except my spark plugs decided they wanted to give up at top end so I had to wait for my new ones to arrive in the mail. I can't wait to see your car done :). The 20G is amazing

break her in and go for broke... see if u can break my hp numbers. 492hp - 387tq at 28psi:durr

I will have a new toy for ya to run in due time.

curt your so full of shit.. your brother has the same setup and he has had a god awful time breaking 350. not to mention you have been chummy with beeyond for years. adjusting the weight on the rollers doesnt mean you made 492 it just means your cheating yourself. it seems like every time you talk about your car the numbers go higher and higher. i find it all hard to believe considering you cant tune for the life of you. i wouldnt let your tune my lawnmower let a lone somebodies car. there is a reason why you aren't in the loop with jordans car because he doesnt need to deal with another zach. stop copying and pasting somebodies elses tune and claiming your as a tuner.

:alcoholicim glad i got that out there

[srt4eh]

heh....

Yea, so my supercharger locked up on me. Go figure. Turbo is hanging on the back of it right now :) i wasn't completely ready to go to turbo yet, but i dont have a choice. I'm stopping by Vulcan Turbo in Waukesha this weekend to pick up a few parts if they are open :confused Shooting for a 2 week full up and running time. GF's bday is next week so thats gonna put me back the 2 weeks (money wise lol)

As for your post curt, I never saw your dyno sheet, nor have i even heard that you dyno'd. Last I remembered was that you dyno'd at beyyond and struggled to get over 250. I'm not talking shit, i'm just saying I didn't know.

[Plum Crazy]

well tuna, thats good to hear!

yea that was mid june... I was heat soaking bad on the dyno cause it was 90+ degrees in the shade. but last dyno prior to that I put down 260hp 255tq in october of 08.

but yea I did dyno my car turboed 22-24 degrees max timing, 24 psi got me over 400.. mixed in my gas tank some vp import fuel and turned the boost up to 28psi and got it to break 500 almost.... took it to gld next day blew the trans drove it home gave it one good last pull before getting to my house got some fuel cut and thats the last time it ran for me:devil

[CobaltSSTuner]

i thought you had issues with your turbo being too big and not reaching full spool or taking a long time for spool?

[Z Speed]

i thought you had issues with your turbo being too big and not reaching full spool or taking a long time for spool?

nah It was just the fact I wouldnt get into the efficentcy range of the turbo till I got above 15psi and thats when the car started moving... I would get full spool about 4000rpms it just seemed slow cause everything would jump on me and then i hit boost and rocket past them lol....

and idk what i did or why i got called a tool but if you could please... talk to me if theres a problem. Im not sure exactly what started it but. I was offended when I was called that when I tried to help you out man. I know ive said a few things out of line in the past due to misunderstanding. I just dont get why theres all this talk going on...

I did my best to help you with your car when we discovered your motor troubles at no gain to myself and to be insulted was kinda a low blow man. honestly all the trash talk needs to stop and be forgotten.

/sidenote/
I've never really had any problems with you aside from some of the things that have been said in the past and things that have been claimed. but thats neither here nor there. I'm not about to have an "e-argument" on a forum. You have my phone number. It hasn't changed since january. If you really wanted to talk to me you could have contacted me. Fact is, derek acts like a tool when he is around you. I have a problem with him. Thats all i'm saying on the forum.
/sidenote end/

Turbo should be on by saturday. Then it will be waiting on tuning. From a certain someone :)

[Flicktitty]

Jordan, got any pics? i needs some.

[CobaltSSTuner]

I do...on my phone lol. Text me, this is my new number-- 920-285-3622. Ill send ya some via text, otherwise ur gonna have to wait till fri, when i can get the gf's camera

[stealthy1ss]

So is the turbo on the car yet?

[CobaltSSTuner]

uh yea lol. Piping is ran and blah blah. Just waiting on a 90 degree coupler that i 3 day shipped outta japan!!!

and i'm running around with a catted open downpipe...no exhaust yet lol

[GMRedline]

Where do the 12 second cobalts hang out?

[That_Guy]

apparently there is a fella who thinks he has a 12 sec one right in milwaukee with the stock supercharger of all things lol..

[CobaltSSTuner]

redlines suck! lol :)
