Regarding my 60' and traction. I really don't have much trouble hooking up if I do a proper burn out with the stock tires. I heard some guy giving someone advice at the track to NOT do a burnout on street tires that it will only make them slippery not sticky. I don't find this to be the case- at least not with the stock Michelins.

Distilled water in spray bottle? Never heard anything about that????

Thanks again Rob for everything. All I have to do now is use some of that felt you gave me. My driver's side CAI tube is rubbing against the tube coming down off the back of the mani- it's already scuffed the paint off in a tiny spot. The passanger side CAI is rubbing the corner of one of he coil packs. I'll see if I can reposition it- I never had that fitment issue before the duals (possibly due to tilting the rubber-y up slightly to clear the AC line on the driver's side).
I remember the spray bottle! Never used it though.

BTW, how in the world do you get a 60' like that on stock tires. Can you make us a tutorial? Throw some tire pressure bread crumbs?

Do a burnout for a few seconds until you see smoke, roll out of the burnout, stage as shallow as possible, load the engine (power brake) to about 1500 rpms, then swap feet (foot off brake as foot slams on gas) and GOOOO!

With that technique I don't feel much wheel spin at all (if any) thus the reason I'm skeptical about investing in slicks.

I think he has a good teacher, but what do I know. :P Seriously though, what Glen said is right, but I would like to add a little more detail.......When you do the burnout, don't sit in the water and burnout. Pull up so your back tires are just out of the water (If you have a good track employee, he will help you). As you do your burnout, look in your SIDE view for smoke and once you see smoke, hold it for an extra 1-2 seconds and drive out of the burnout! Don't let off the gas when you are coming out of the burnout. You need to actually give it a little more gas while you drive out of it because the tires will want to grab. I found the sweet spot staging the car from 1600-1800 RPM or right on the verge of the coverter wanting to lock up.

I will also note that the track prep is VITAL for you to acheive 1.7 60's. Atco is great and Glen and I are lucky to have this track near us. We <3 Atco!

I forgot to attach this pic....yes there was a bit of interest




PS Yes, stock exhaust still- why? Does modding the exhaust actually yield performance?

Well, thats how I do it but I sit in place and spin if I floor it out of the box. I have to let off the brake and after moving a few feet, gently go full throttle. My best is 2.xx 60' at 109.74. I even see the traction control light flashing in 2nd as I'm going down the track. I'll smoke the tires a little more the next time to see if it makes a difference. Thanks for the tips.

Congrats cross hair, you did good!
For these cars? Yes. Impressive, not so much. Still enough cars around to whoop up on 112mph trap speeds.

Crossfires with 3 mods are trapping 112 and crossfires with 4k in mods are trapping 112. THAT is unimpressive.

To me a 12 sec car is not fast, but fun.

are you crazy?!?

whats unimpressive is that any one and their mother can pay someone to mod there car and go to the track all the time with an auto trans car that runs fairly consistant.... there are not many people on this forum that tune there own car or really go with a unique setup... you guys my rip into j-fire for doing all the bolt ons instead of a pulley mod but at least he is different.

i am impressed the power these cars can make with little mods but it can only go so far before it is unimpressive.

My guess is your track isn't prepping the surface, but honestly I would need to see your technique to really say for sure.....What track is it and what nights do you run?? You need to run the car on a gamblers night or a bracket race. They prep the track when there are competition runs......

LOL. You said exactly what I just said. Just in a different way

I too am impressed the power these cars make with little mods. Hence why I said 3 mods to these cars tend to yeild about 112mph times. Impressive for a crossfire automatic 6 banger. Nice car! Fun car!

Fast? Not really. 112 mph is not fast in my opinion. It would have been SMOKIN 10 years ago, but times change. A stock 05 vette traps 112+

Like you said, these cars are impressive with just short mod list. I agree, 3 mods to a crossfire and running low 12s at 1teens is impressive for a crossfire.

To me, a crossfire with 4 grand in mods running the same is unimpressive.

What is the holdup? I dont have that answer, if I had to guess, id start with the computer and the highway gear ratio. Then there is the ever so brought up supercharger/IC. Those need to go IMO.

You guys really want to start to raise eyebrows about the Crossfire? 120+ traps will do that.

I suppose "fast" can be subjective. It's all a matter of perspective. If you are used to driving around in an LS7 I can understand not viewing the SRT6 as "fast". However out of the 100 or so cars there for street night only 3-4 of them were faster than me. A few of them being a boosted LS2 Vette, and an E63 AMG. Again thumbing through the back of a Car & Driver and skimming the 1/4 mile times of several hundred cars only a few are faster and they include the likes of Ferraris, Lambos, and Bugattis- though maybe ET doesn't count for you?

Considering "fast" is a matter of perception- what other car(s) do you own which make you feel the SRT6 "unimpressive"?

PS My traps ARE admittedly quite low. I should be over 115, but yet again, it's a problem with the tune.

but well again i will get ripped on for being a bench racer haha but i dont give a sheeet.

a srt-4 can make 122mph traps and still only run 12.2.... so based on a crossfire also running 12.2 at lets say at 114..... which ones fast? lol

my srt-4 pulled harder on the highway... thats about it... other wise i am more than impressed with the crossfire in comparison.

Oh man,
I can see where this thread could go.
I dont want to turn this into a fast/quick debate with other cars/mph.
I was not ripping on cross><hairs car or mods. I think his mods are sexy and would love to have a similar setup! Im sure he will get better times out of it, I know it. Get a boost gauge, new tune, and you should be in the 11s no problem. I am not doubting his car will hit 11s.

And to everyone who is in the low 12s in the 112-115mph range I am not ripping on your cars either. Like I said, I like the crossfire, its impressive for what it is and I LOVE driving mine. Its fun as hell! Under $1500 in easy parts = 112mph. Im down with that.

I just hope that the next "common" thing with these cars is 120mph traps. That would be awesome to see. Just dont know how we are going to get there yet.

And to Tamadx's point on the SRT-4s. Yep alot of those little boogers are trapping over 120. Sure they have more mods then a handful, but they are mods that are avail, off the shelf and you are not paying a MB premium with them. That is just one example of several common cars that are being hopped up and can easily whoop up on our cars.

Have fun!

Carolina Raceway Park, Puerto Rico. I usually run Wednesdays or Thursdays, but for the last month it's rained every Wednesday and Thursday. They prep the track better on Wednesdays because the big boys come to practice. Thursday's are driving on ice. They race on Saturdays. I'll see if its better on the weekend, if it ever stops raining here.

Be patient, there are great things to come from this camp! When we figure out all the little bottlenecks for air and fuel delivery, LOOK OUT!

One thing about the Cross car here if he is leaning out because he's added new mod's on an old tune of course he's not going to be running top numbers. Yes Cross Exhaust will help not night and day but should breath better near the top and give you a few mph. Tune (to make use of the new modifications) and exauhst I think the car should be in the 11's no problem maybe even to the top of the list, 11.7 seems very attainable.

it still bugs the heck out of me that our cars don't need exhaust upgrades!!! we've got guys running 11's without changing anything on the exhaust side!!!! i can't say i can think of ANY other car where that is the case. anyone?

I'm still stock exhaust, and cooling. Other AMG's can hit 11's with other mods besides exhaust.

Corvette. Cobra. Of course Viper. All are quite capable of doing it, yet you see them upgrade the exhaust because it yeilds results. I am not happy about this car not responding to exhaust mods. To me that says there is something bigger holding this car back.

What could cause a car to make the same power regardless of it making 17psi or 22psi and regardless of a stock exhaust of opened exhaust.

One thing comes to mind. The computer.
