not sure what happend.. thought i blew something?!?
 

Well... I got my turbo installed and only have a basemap on it... and you guessed it... I ran it fairly hard today. To put it as simply as i can.. I was at about 6-7k and it goes BOOM and a small cloud of black smoke goes out the back. Then it shuts off.

I originally thought that I either snapped a rod/ring lands were fried/ or bent a rod. However.. It cranks but wont turn over. SO I did a compression check. All are within 20 psi of eachother at around 180 (was like that before I went turbo). No really loud noises or anything when I go to crank it so I doubt its anything internal. (not sure tho).

SO.. that kind of leads me to believe that its my timing belt. I thought my belt could have skipped some teeth or something. I took the valve cover off and couldn't tell much from there. Is it possible for the engine to do something like that and not start up? Or did I seriously fcuk something up? :( .

After all of this is done... I will NEVER drive another car unless it is properly tuned.

cranks but doesnt turn over eh?
Aren't those synonyms?

anyways, you can find out if the belt is broken most likely from pulling the upper timing cover

Re: not sure what happend.. thought i blew something?!?
 

take a look at your plugs

Re: not sure what happend.. thought i blew something?!?
 

yeah Ill have to check the timing out tommarow...

as for the plugs, they all look fine.

turboed gsr motor w/ a basemap.........

^^ yeah, it takes like two seconds, literaly to check the tbelt or if it skipped. I would pull the pan and if you can see anything.

Re: not sure what happend.. thought i blew something?!?
 

If the tbelt broke wouldn't get stuck and the motor wouldn't be able to crank over??

Re: not sure what happend.. thought i blew something?!?
 

I had similar effect when my ignition control modul died. Check if you have spark.

Re: not sure what happend.. thought i blew something?!?
 

thats for the good info thus far! I will deffinelty check if I have spark. Thanks a ton!

So just a loud ass backfire and then nothing? Sounds like ignition to me, if you bent/threw a rod you would know it, if the compression is the same as it was than chances are your ring lands are fine.

yeah my buddie's ICM went on his GSR too, just started it up and then it shut off.

And if you snapped the t-belt you wouldn't have any compression :1
