Asked one of my friends to take a video.
But I don’t have a helmet lol! And I’m really tall haha.. So we’ll see what happens lol may only get one shot before I need to go for a drive and pick up a helmet from another friend’s cabin..

 

sweet lol. Good luck my brotha. Eitherway you'll get a chance to see what your car can do with its new Meth system

 

We're gonna run 20 tomorrow! Someone asked me how many ponies she had today, had to do the math when I got home. I really need to get her on a dyno... steady 268 ft/lbs of torque at the engine at 6500 rpm would put me around 270whp or 330 engine hp lmfao IDK... that seems high.
Won't be any rain tomorrow unfortunately it would have cooled things down a bit.
Its gonna be hot but I got 16L of methanol mix so why no go make a couple pulls.

 

We out here! First pass should go down soon it’s about 28C right now cars Just cooling down Ready to go!

 

Well not as good as I though 14.67 and 89mph. I ran 15.09 at 89mph last year. Granted it was about 10C when I ran last year and it was 30C today with 70% humidity.. Definitely going to try again soon. Took me a few tries to break 14s car was loosing traction off the line found 20psi on the tires worked best.. did my first burnout! And then about 3 more. Had a blast was a great feeling to break below 14.7 without a foul!

 

Drag Strip tech guy drove a 2.4 SS and wanted a friendly race..

 

Got 7 passes, on the final run I figured out how to modulated a good burnout without hitting power cut. Gonna go back when it’s colder, should be able to do low 14s for sure maybe it’ll do a 13 in September/ October maybe I’ll have to throw more parts at it lol

 

Great times my brotha. I'm sure you get 13's soon. Just need the temps to be cooler like you said.

 

Awesome job brotha . I wish we had a drag strip in NS. A lot of people would use it including myself lol. 14's is still very impressive considering how hot and humid it was.

 

thanks man I was a little scared for a moment getting 15s hahah.. it was nasty hot not a cloud in the sky I’m so sunburnt lol. Will certainly pick up lots of power as temps decrease
That would be sweet, pretty sure we’re getting another one here right outside the city..lol

would’ve been sweet to race a modded cobalt like yours today tho, the one I raced was bone stock le5 manual

 

What tires are you on? Good sticky tires shouldn't allow for a burnout off the line (unless you're dumping the clutch at a super high rpm). I'm also assuming you at least do a quick burnout to clean the rubber pre run?

 

Firestone Indie-500 I thought they’d be good for the strip.. pretty sure they’re branded as a radial.
im auto.. So pull up e brake and smash accelerator but most of my burnouts only lasted a second. The very last one I did I went all in, modulated the burnout for a good 6 seconds. And to be clear I am water boxing it..

 

Don’t think anyone got a good video of burnout but Here’s something.
video of me running by myself was actually a 14.6969@87.60 reaction .29 Foul

 

You’re not going to run good times without drag radials or slicks. I broke into the 12s with Hoosier tires.

 

****.. I could get a dot approved 225/50r16 would fit my existing rims. What size are you running and rim width?

 

225/50/16 Hoosier dr2 with msr 013 wheels 16x7.5 +38

 

interesting thank you!

 

You're not gaining very much mph on the back half, and you should be. I'd guess/bet that it's from very bad heatsoak. Are you sure your intercooler pump is working? Checked or confirmed fluid flow in your intercooler setup?

An interesting mix of parts in your sig. If you have all that and are spraying meth... I have to think something is wrong. Even without the meth... your back half is what's killing your time. Reminds me of when my I/C pump died.

EDIT: For reference, my S5 gains 20 mph on the back half (1/8 to 1/4). The car you were racing gain 25 mph; which I think is about what my LSJ picked up with GM Stg2 and a 2.8" pulley. Even the guy with the 2.4L that you raced picked up 15 mph. You picked up 12.

To reinforce my point, your quarter mile MPH is barely better than some of the other 2.2's on the drag list that are two full seconds slower; IonNinja ran a slower time, but with a half dozen more mph: https://www.cobaltss.net/forums/drag...thread-285886/

The Firehawk Indy 500's are more of a road coarse/autocross tire. They have a stiff sidewall, and you're not going to want anything with a stiff sidewall. And essentially all DOT tires for the last 20-30 years have been radials... I don't think it means what you think it means.

I was always taught not to water box on street tires. Additionally, big smokey burnouts tend to not be useful on them either, because you end up overheating the tires.

 

Solid info on tires thank you sir.

the engine was horribly heat soaked you could’ve cooked meat on the valve cover. Supercharger was Ice cold all day.

I’ll do some testing with my pump. It does make a weird growling noise with key on, but seems to be moving coolant looking at the option b tank. Would orientation matter at all? I have the pump taking fluid from The out on my S3 heat exchanger Going to the in on the dual pass endplate

Maybe my lsj he in/ out tubes are a bit pinched slowing down the flow? My s3he is starting to get damaged from bugs on the highway, might be worth a shot switching to a griffin or stealth all together

 

Pump defiantly works. Option b is bleeding, just put my hands on the pump before and after hoses they’re moving fluid

 

Edited my above post with more info about why I think you have a problem.

Do you know what your IAT2's were? Orientation matters for the flow of coolant, but that sounds fine for the hose routing. Are your I/C cores oriented properly? I seem to recall needing to flip the direction of two of them when running a dual pass.

You can straighten the fins on the S3HE, it's just a PITA to do. Very time consuming and requiring slow work. I don't know anything about the S3HE. Are you going from the LSJ HE into the S3HE, then to the I/C, then to the OptB tank?

 

Okay thanks for you update. I understand Your right I should have totally picked up more mph than the le5...

Yes I flipped them and made sure to clock them correctly 100%. Not too concerned about the fins themselves but I have one horizontal bridge that has been impacted by a bug pretty bad..
Going out of the intake manifold, my option b meets up with a Y fitting goes straight into the LSJHE, then into my S3HE then to the pump, then to the in on the manifold.

putting my hands on the hose before and after the pump, squeezing the hose, I can feel coolant moving quickly around my fingers. Option b air line is moving some coolant so I would think the whole system is pushing coolant..
I do have the IAT2 sensor but no pigtail.

 

Really need to put a window screen on the lower grille Or something

 

Could this do it maybe? The tubes still flow but they are a bit pinched..

Whole time I was at the strip coolant temps were under 87. Kept the car off pushed it when possible. Funny both my 14.7s were hotlaps.

On the drive home I left at about 80C and it climbed to 94 out of nowhere, took an hour to fall from 94 to 91 on the highway which is unusual.
Normally coolant temp is 87-89 max. 91 is a blue moon.

 

How much timing should I be running in 3rd?

Yup even my first pass with 2hrs cool down only picked up 11 mph in the last 1/8..
