I put back my GM Stage 2 kit for the winter but I'm still using the NGK BKR-7E spark plugs. I'm getting knocks, up to 3-4 degrees each time I do a WOT pull in 3rd gear. I'm using 91 octane gaz... despite this is not 93 octane, I still never got that much knock before! I have to say too that our winter is particulary cold here, around 10F during the evening when I did my WOT pulls.

I have to add too that no, I don't do those pulls often and during a long time, pretty dangerous but each time I stomp the gaz in third gear, I'm seeing continuous knocks, like I said around 3 to 4 degrees, this is quite a lot and I'm wondering why.

 

are you running the 2.7 and 60s on the gm stage 2 tune?

 

well the problem is not the 91 octane gaz, it's that you are using 91 octane gaz without naaaaawwwwsssss!

 

Says he has ottp tune, what is the smallest pulley size you can run on stage 2 tune?

 

Nop, all the setup you see in my signature is my SUMMER setup... my winter setup is the same, except that I put back the GM Stage 2 PCM, 42 lbs injectors and the GM Stage 2 pulley. I keep also the same spark plugs, the NGK BKR-7E, one step colder.

 

i don't see what kind of gazzzz you are running in the signature

 

Damn I have the same problem! Crazy knock at the top of 3rd.. My car doesn't move at all either...

And I have changed my plugs to BKR7Es as well.. and the Autolite equivalents too.. (1 step colder)

Think it could be the plugs?


I'm on stage 2 with a 2.9.... Hmmmmm...

 

First of all why the hell are you beating on your cars that hard in the winter at these cold temps? Your asking for trouble. These cars knock. I have seen people knock stock, stage two, fully built. Not to mention our knock sensors suck and cant distinguish between real engine knock and enviromental knock or gear clash.

 

^ I think something is stuck in your vagina

 

Dont beat on it too much in the cold and you should be fine. Before I went E85 I would see a little knock at anything below 40 degrees F outside, on the same sutup I would see none above that temp. I would imagine it to get worse with cold

 

why the **** are you going wide open when its 10* outside??? i haven't been wide open since like....mid october

 

^ Something is stuck in your vagina too

 

no. something is stuck in my brain. its called "i know how to treat my ******* car"

 

That time of the month?

 

nope. but maybe theres a reason i'm number 10 on the stock m62 horsepower, number 8 on torque. 60k miles on the stock clutch and it STILL doesn't slip. and STILL pulls 2.0 60' times. cause i don't beat on it and i drive it right. especially during the winter

 

i saw a video of you at the track with a slipping clutch lol

 

yeah the one of me on drag radials?? thats cause when i DO hook. it can't hold. why do you think i stay with street tires now...

 

That's wonderful bossman Don't get your panties in a bunch

 

gotcha just checkin ya brah

 

i don't wear panties. thongs are so much more comfortable. and they don't bunch.

 

Definitely. Thongs are sexy

 

I'm not beating it that much at all... just when the road is clean, and when I'm passing on that same road which has no car circulating and which is looong and never seems to end. I did those WOT pulls in fact 3 or 4 times, during like 2-3 seconds nothing more and getting back to normal speed but each time I always saw that knock.

And in those 3 or 4 pulls, 2 of time was to be sure that I really could see knock and that I didnt dream. But I can't see if I had any during the winter last year because I didnt have my Interceptor gauge. So... I'm wondering if this is only the cold air or my plugs. Maybe we should put back our stock plugs (not one step colder) during cold time?

 

I hate noobs, people like this ruin this forum. Hey bud, didnt you post a thread titled "Im an idiot theres something wrong with my car it dont pull hard or hit veeetaaaaac?"

 

he's been around almost a year longer than you, and both of u are nubs btw.

 

You didnt exactly specify, you said you see knock when you "stomp the gas"... are you seeing KR at the top of the gear? Througout the pull? Or just right after you hit the pedal? It is normal to see burst knock when first hitting the gas. Its certainly good to tune it out.. but it is not abnormal to see this. However if you are getting KR through the RPM range or in the high RPMs, I would stop doing WOT pulls until you figure out the cause.

It is also possible that if you are just running the full GM stage 2 tune & parts... that it is off because of the 91 octane. The GM tune is made for the 93 octane which is what is supposed to be ran in the vehicle. Its very possible with the lower octane, the timing is not correct for it, and causing the problems. Unless your tune is specific for 91 octane than I would start putting 93 in there. Not a good Idea to run a lower octane than what is recomended for the vehicle.
