if you're from Oklahoma you should roll with us to the Lonestar Bash this weekend.

 

I'd love to but already got plans to go to Import Face-Off in Thunder Valley. You know, since those imports need a lesson lol.

 

Good luck man, I've never been able to get a good run in there because the prep is so shitty. Wish you could roll with us, we are gonna have a huge cobalt cruise!

 

Yea I much prefer Tulsa, Thunder Valley really does blow. Have fun fellas. Represent OK proudly.

(sorry to thread jack)

 

Thanks. We'll have to meet up there some time. Every time I go there, theres always some cobalt owner running up there. Maybe set up a day where we can get a bunch of us to meet up and hit the track.

I didn't know about CHevyfest. I'll have to look into it.

I had no idea it was all new surface! That's awesome. They changed the Helmet rules this year, too. SNELL 2000 or better. Was 95.

Thanks again. I didn't experience any cut out in third. I do have the COT tuned out as well. I feel like the only thing I can do to improve is get my launch down for a better 60' and to nail my shifts a bit better.

This car has low 12's written all over it.

 

WoW! Good time and trap! We got the same mods except I have a new IC. We even have the same tires, lmao. Im surprised you got that quick with these tires. Im impressed/

WHo tuned you? what boost you making? I got a BYT HPTune right now and my dyno was 299whp and 327trq with slipping clutch. Do you have an aftermarket clutch?

 

great job dude!!

 

Thanks, man!

What intercooler did you end up going with?? I think that and meth are my next mods.

Same tires too?! Which, the Conti's or the NITTO's? I ran the Conti's this time and my NITTO's are going back on soon.

I tuned me.
With some help from my previous tuner and his dyno that I've been using since I started modding. He's been tuning GM for years and I learned a lot from him. I also learned from Term and BYT as well. The car runs about 24-25 PSI right now. Clutch is stock, turbo is stock, tranny is original as well as the rest of the drivetrain, no suspension mods or anything. All that's done is what's listed in my sig.

I feel very fortunate that everything is holding up and working so well. The only things I've had to replace were the rear brakes last year and the MAP sensor that blew out about a month ago.

 

Good job for street tires!!

Have you tried running your tires with a bit more pressure? I know alot of people seem to have better luck in the 28psi range on street tires as they tend to bow upwards in the center if you run them with low pressures.

You might of already tried this...but I figured I'd lend the advice anyways.

Keep up the good work!

 

28PSI got me up 12 sec pass too. Alot less wheelhop

 

Thank you!

And, no, I haven't tried more pressure.... I get what you're saying about the tire bowing up in the middle with less pressure... but more air presure? That definitly reduces contact pacth, though.

Someone at the track when I went for my very first time told me about how to see your contact patch and that would tell you how much pressure you can run. Basically, you just let air out a little at a time, roll your car through a small puddle on flat ground (just to get the tire a little wet) and look at the tread path on dry ground. You can see how much of your tire is actually touching and you can deflate/inflate accordingly... That's how I found that about 24 PSI gives me the widest contact patch in these tires. This is all on the drive tires only.

BUT, I am all for trying new things and I'll give the 28psi a shot next time I go. I'll do whatever works!


I don't experience any wheel hop, really. Only when it kinda bogs. I slip the clutch a lot to balance wheel spin with grip.

 

Nice run OP

I wish I could pull off a 113 trap lol

 

Thats a good trick! Never thought of that.

Give 28psi a try...worst case it doesn't work as well and then air them down to 24 again.

The idea is that when the pressure gets low the center part of the tread bows inward towards the center of the wheel...I'm not sure why that happens but thats the threory...lol

The best way really is to start at 30psi and go down 2psi every 2-3 passes....write down your 60' for each pass....and see if on average you are getting better 60's, once you notice them getting worse go back up 1 psi to they get better again....that should be your best tire pressure.

Alot of the time that doesn't work tho since its hard to get that many passes in in a day.

Let us know how it goes!

 

Will do! I'll give some of this a try. I'm all for new methods, ideas and suggestions. I just do what I do because it's worked for me so far.

Thanks again everyone.

 

That's where the sweet spots are. It's a tad hard on the clutch, but if you want the best run possible, it must be done!

 

Dont forget to air the **** out of the back tires, i run 45-50 psi back there.

 

sedans FTW!

 

nice time man.

 

I was gonna say no way but that proves it. That is one absolutely hell of an epic run.

 

THANKS!

Meth Kit should be coming in, so I hope that helps a bit. Gonna air up the rear tires next time. I didn't do it for this run... didn't even occur to me oops.

 

Nice times!

 

this is still the best run with your mods at the time...what was the weather like?

 

good techniques..my redline is set at stock level though(6200), so i have to shift much quicker...lol

 

Weather was ideal for racing. I think it was just about 60 degrees, track was well prepped, some wind gusts but nothing bad, very low humidity and I had about 1/4 tank of gas.

I put mine back to stock for a while and then raised it to 6500RPM like the GMS1.

 

nice run gremlin!
