So I finally made it to the dyno today, this is my best run. I was thinking this is where I should be at. I am pretty happy with it. Mods are in the sig...


Heres the overlay of all the runs I did.


Any comments/input?

I am uploading a video of the pull right now, the intake sounds mighty nice

 

nice numbers!

 

Very nice! Now for a header and dowpipe!

 

Yeah, header and downpipe are next on the list I think. I need to read and see exactly what mods are allowed according to the SCCA autocross rules.

I also want to get some engine monitoring going on, but I need the dual gauge bezel for my gauge cluster!

Video of the dyno: (listen to that supercharger )

 

i love that sound!

 

Great numbers man. The car sounds great.

 

Nice numbers indeed. I have a Q for you tho... Have you had someone (or yourself) played with your S2 tune at all? Im just wondering cuz i have S2 also and my A/F looks NOTHING like yours. Yours is smooth and looks pretty good around 7k. Mine looks like someone blindfolded a 3 year old, gave them a crayon and told them to draw a straight line.....

 

Wow those are some good numbers, and the car sounds great!!!

 

Thanks for the compliments guys, I love the sound of the car too. Just wish I could get it spooled up like that more often!

No, the tune is the same tune from GM. Do you have the same mod list I have?

 

good numbers, there,when you have the other bolt ons and maybe a tune you will blow past that. Congrats

 

Yeah, I am guessing after a couple more power upgrades, it might be time to look into a clutch or axels. 260hp isnt far off!

 

All i have is the S2. I just ordered an intake tonight. But from what i have seen both in person and on the forums, there is no way an exhaust and an intake will level out your a/f ratio like that. I just think my car runs pig ass rich, more so than others. After my last run, there was unburnt gas coming out of the tail pipe....

 

Where is greensburg? it might have something to do with your elevation off of sea level. not sure though, but you never know, do a dyno after your intake and see if that helps. It has to help at least some I would think...

 

Might have something to do with the updated tune for S2 for the stalling/idle/whatever. I know they said that they didnt change any of the tune itself but yours is just waaaaaay smoother than mine. O well. Thanks for the input tho. Ill have to look at a few things.

 

you could even stand to lean that out a half point or so at the top there, probably squeeze out another 10-20whp by doing that... ecotecs don't mind bein a little lean they handle it way better than the v8 boys

 

Good numbers!

 

yeah, I am thinking about throwing a stage three pulley on there and see what that does to the AFR. I think that might lean it out a tad, but still be nice and safe

 

11.8ish 11.9ish at wot?
dont touch a thing.

 

so you think I should leave the AFR alone? maybe its time to get some suspension mods, open up the rest of the exhaust and get some monitoring gauges in there...

I am still in the stages of n00bness, so thanks for all the input guys!

 

From the time ive spent learning about these engines, if you want power? lean it up all you want.
just dont expect to be driving it 12 months from now.

If it were my car i would be very happy with that kind of power at those nice safe A/F's
lookin really good to me.

 

I like to run 12.2 on WOT on the 2.2 turbo ecotec cavalier i have. Keeps the EGT numbers a bit lower

 

i think its time for some suspension upgrades, and maybe finishing up the exhaust, but I am siding with you anomaly, i like the safe part

 

Great ! Love the video. Things like this get me pumped for summer....

 

Yeah isnt the sound of that thing revving all the way up just awesome?!
