Well , I had a GREAT day at the track today . The NEVER happens scenario of not a big car turnout , PERFECT weather , and really good track just worked today . I got ALOT of time to get a feel for my car . Started off really bad ( my 1st pass was a 15.53@99.8 ) then got proggressively better and better . This time I got the car off the line pretty good letting out on the clutch qwikly but not exactly dumping it , and easing in onthe throttle . 1-2 shift was the absolute bitch of the day , every time I had to peddle it on the 1-2 to prevent wheelhop and tirespin . I got it under control though and ended up with some damn good passes . First off , the sole power mods on my car are a Injun CAI and a 2 1/4" Edlebrock SDT muffler with all the rest of the exhaust piping stock . I ran on stock P. rosso's , found the psi to best at 27 psi for me . I dont have any suspension mods or poly mounts at all . Weather was great , clear skies and upper 40's , I dunno bout the humidity , and the elevation is 662 ft above sea level at the track I raced at . All runs were launched just off idle to 1500 rpm , going over that was a MESS , lol . All 21 runs I shifted at 6400 , all runs were powershifted and I did have to shortshift 4th just as I was about to cross the finish line to prevent hitting the rev limiter . I only posted pics of my best times , I had 21 runs so it'd be a bit rediculous posting them all . I was car #6 . Im happy and aggrevated , if I had poly engine mounts , trans mount and control arm bushings and a good tire I could been deep in the 13's on every one aaaand cut possibly 1.8x 60 ft , grrrr It was MPH'ing like a champ today , its the happiest surprise of the day considering my modlist , 103.23 was my best

 

Powershifting on every run....21 runs....DAMN BUT AWSOME TIMES dude. 13.9 with intake and muffler. Hows that clutch holding up? Still strong?

 

Nice Runs

 

whew that car was beaten down !!! Good runs though

 

great runs, I knew it could be done....

 

The car and the clutch are still strong as can be . Alot of the 1-2 shifts werent powershifted but all the 2-3 and 3-4 runs were . I dunno , alot of people would say thats dumb , but I LOVE to bang gears and get the most I can . I dont whine when I break stuff if I do , I know Im hard as hell on my cars

 

Awesome runs! Hopefully i can dip into the 13s next sunday, Great 60 times also, best i could pull was 2.389.

 

Thanks guys .

Another wierd thing . When I let the car cool down for a long time , I could never get a good run 1st time out after along cooldown , my mph would always go down to 100-101 . The best runs and mph came after hot lapping , Id make 5 or so runs in a row then let the brakes and the clutch cool for awhile then do it again . Supercharger outlet temps would skyrocket to 120's in the lanes and then come down pretty qwicky to high 80's and low 90's while I hazed the tires off and staged , always was 112-115 at the end of the run . Coolant stayed dead steady at 183-185 on all runs , again though itd creep to almost 200 in the lanes . Coolant temps also dropped qwikly once u started generating RPM .

I thought this car would HATE hot lapping , was pleasently surpried the opposite was true . I bet it wouldnt like it too much on a hot day though , or even a warm one .

Good luck shortbus

 

Goodluck to you also and great passes!

 

Great runs! How long were you're burnouts? Also, how long of a cooldown would you say your car likes? I'm going to the track in two weeks bone stock, and I'm just trying to get a feel for what works for other people. Thanks

 

Not trying to hijack the thread but when i went to the track i didnt really bother doing a burnout seeing as you cant really warm up tires well unless they are drag-radials or slicks, at most i did a small chirp up to the stage.

 

I didnt do a burnout "persay" . I just drove completely around the waterbox , lined up in the grove , popped the clutch in 1st , no brake and just hazed the tires just enuff to scrub the dirt and anything else that might be on them off . You try doing burnouts with a normal radial tire and its pretty much pointless , its just makes them greasier because it ***** the rubber up . You only do burnouts in a drag radial or slick because theirs compunds in the tire that drawn to the surface by the heat .

My car was loving being hot lapped , it got qwiker after 2-3 runs in a row . I just kept watching the cooling temp and the intakeair 2 on the Aeroforce , and was pretty easy to keep both temps consistent . The supercharger temp creeps up QWIK when the car isnt moving , but it recovers qwickly once you start moving . I could sit in the staging lanes , its creep to 120 real fast , but if I brough the revs up to about 2000 it's start to drop pretty qwikly also . I was cooling down to give the brakes and the clutch a break to cool only .

 

sweet times and great driving. I'm going to the track wednesday hopefully.

Good runs

 

Very nice, I like your 60 foot. Definately means I am doing something wrong.

How do you launch, did you ease into first or where you taking off at a particular RPM?

 

Nice runs! I can't wait to hit the track again soon. Turbotech needs to send me my Ingalls damper first though!!!!

 

Nice runs man.

Trapping at 102MPH is damn impressive, thats really movin' out

 

i'm amazed that only an intake and exhaust gave you you a 102 trap, stock one of my friends could only get a 95. Awesome driving man, you just **** on my stock time lol.

 

Wow great times Silver, your SS is hauling w/ that trap speed, especially on a stock pulley!

You've got yourself a beast.

 

I'm really impressed for the first time in a while. Nice runs man. You sir have a driver mod.

 

Adam trapped 102 with just an intake.... it is amazing isn't it

 

Indeed, I should PM him my avatar, he deserves it!

 

Thanks alot guys , haha ... this car definately makes you work for greatness . Goood luck to everyone going racing . Tofu- It was your AWESOME driving skills that kept me diggin to get the best outa mine . Im getting rid of this chambered Edlebrock muffler , and bought the stuff to a mandrel 2.5 back off the resonator with the straight thru Borla Turbo XL muffler . Hopefully I can have the great weather we had a few times before it starts getting warm to test that . Next step for me after that is control arm bushings and a motors mount and a 3" pulley

I just found the sweet spot getting the car moving cleanly without really slipping the clutch . I have one short stretch of country road I go on every day to and from work , so I practiced alot out there and used the same technique at the track . My launch RPM is never over 1500 , for me anyways ....I just cant get it under control enuff at a higher launch RPM with the stock tires without majorly slipping the clutch . Right now for me its just one fluid motion of qwikly releasing the clutch and at the same easing in the throttle . There was jus lil room for error , if I tipped in a little too much on the throttle it just started wheel hopping . For the 1-2 shift , I had to kinda peddle the throttle just tiny bit ...If stayed to the wood on that shift I coulda pretty much spun all the way thru 2nd . Another thing that helped me , I followed the drag cars when I could If I lined up after a drag car went , after he did his big ol burnout with the slicks and got the starting line all hot and sticky ....it helped out immensely . Both 13 sec runs were ran just after a drag car made a pass . Just keep on practicing man , youll get there .

 

i have to say that you and tofu are really the only 2 people that are keeping me interested in the cobalt. I keep reading all these threads about track days and their horrible times with all their mods but you and tofu have broke 13's now with next-to-no mods. so you guys really are doing great. congrats!!!!

 

Great times...
