Going to the track tonight with the new combo, 2.5" pulley, 60lb injectors, HPTuners software, and one heavy right foot!

I plan on testing the limits here so i would like donations for when i break in the name of research for you all!


The weather isn't looking to great but i'm going to try it anyways.

 

goodluck. and godspeed my fellow cobalt owner!

 

GOOD LUCK.... SOUNDS LIKE THE COMBO i'M GOIN FOR... HOPE YOU DON'T BREAK ANYTHING

 

is the HP tuners software a recent upgrade? how exactly does the hp tuners software work exactly...someone tunes the car for u or u need a laptop...good luck

 

You need a laptop and lots of knowledge, otherwise, bad stuff can happen. Read up on engine tuning and how all the components work together. Then, baby steps only, you can tune your own car using HPT

 

I'll give u 5 bucks if you blow the blower I doubt the engine will go. Good luck man let me know how this set up works I might do it myself you should hit a 12.7 or 12.6 maybe more depending on the tune you put on it anyways good luck!

 

Good luck! Hope you make you alright. I'm ordering HP Tuners in a little while. Can wait till tonight to see what you ran!

 

Good luck!!!

If the blower does blow, can you change everything back to stock and get it repaired under warranty?

 

GL dood... BTW... I wouldn't let the old lady see this!

 

Good luck Rob, you've already got my $5.00 (IDDVII race gas).

 

10 bucks for a broken blower. thats 15 total.

 

i doubt it. but they may warrenty it as defect. but i has sure seen some abuse

 

No sticking abuse hear man! Yea right! Just went out an drove it on the street. Only 12 degrees of timing and HOLY SH##!!!!! Man this thing feels like a rocket! Wait till i get it up to 24degrees!


Wideband showed a steady 12.1 to 12.3, no KR from 2nd thru 3rd. Maff is hitting 10200 now with this pulley

 

Good lord! Good luck man, do us all proud and his some mid 12's! How did she feel w/ the tuning done? I was talking to Jmc and he said he's pretty sure we could see a good bump in power just from tuning alone.

 

Good luck Rob!


I will say though... That once you get into HP Tuners and tuning, ect. ect. ect.... This is where alot of the tuning of the Cobalt SS will differ from person to person. I mean, hell.. If you can't tune, you'll never be able to go further than HP Tuning.. Damn it's got so much promise, I can't wait to start messing with it.

SWEET !!!!

GOOD LUCK

 

Well unfortunately i got rained out tonight!


I did do a run from 25mph to 85mph and logged it. Looks and feels incredible!! The 1-2 shift is unreal, 7100 ALL THE WAY DOWN TO 3890!!!!!!!!!!!!!!!!!!!!!!!!!!!!! YIKES!!!

Bumped the timing up to 18degrees as well. Can't wait to get to the track! She feels like easy mid 12's!!!


For those of you w/HPT's, i'll send you the log file if you want to view it.

 

rob you do know that you need a car at my meet right

 

That sucks about the rainout. No kr with 18 degrees? What were your IAT2 temps? Also, what was your IDC and IPW? I'm sure there's plenty of fuel, I'm just curious. That should be 19-20lbs of boost, right? Maybe I better just call you.....

 

Hey Rob, I'd like to see a copy of that log file. Its good to hear of no issues with an advancement like that in timing. I can't wait to get those 60# injectors!!!

 

Sweet please do Rob....
I just order the 60's and the 2.5 from Intense.
I'll IM you my email

 

At 7100 rpm i had 80% Duty Cycle, 12.0 commanded AFR, 12.1-12.3 on the wideband, 18.6lbs of boost.

My timing was rock steady as well as the AFR for the entire pull from 25 to 87mph.

Not bad for 10 mins worth of tuning

I want to work on the everyday driving habits now. I don't like the timing dropping to single digits after the shifts.

 

2.5???!!! isnt that gonna kill your blower????!!!!!

 

Only 10 minutes.....
Give Rob a week of tuning and he will have the first 11sec street driven cobalt

Were all taking notes and following in your footsteps...

Thanks for being the pioneer in all this.

 

My prediction is up to 307 whp with the more timing you will be able to add on pump gas. Also it would be interesting if you get your air filter and plugs replaced ).
