Got back from the track.... ummm

[Motorhead350]

Tonight the weather was the best it's ever been for my car at around 60 degrees. I met up with a group of Acuras and killed every single one of them even one guy with slicks and no interior. They were still a cool group of people, but they didn't seem to pleased to be losing to a big black two ton sedan. My times weren't as good as I hoped, but I'm just guessing it is because all I have are the street tires. Heres info on my best run of the night/ever:

R/T : .250
60': 2.188
330: 5.961
1/8: 8.959
MPH: 83.35
1000: 11.541
1/4: 13.731
MPH: 103.10

I just don't understand why I always see that our cars are supposed to make 12.9 with everything else stock yet I can't even get a 13.3. I mean you can get a Marauder to do 13.8 natural and lower and I can barely beat those guys. Could it really be just lack of slicks??? :confused:

Here is a time from a Charger SRT8 with slicks that I lost to and I was assuming would be my time if the weather was perfect.

R/T: .102
60': 1.880
330: 5.403
1/8: 8.303
MPH: 84.92
1000: 10.826
1/4: 12.959
MPH: 106.23

Now why can't I run these times? :mad: Is it just because of the tires? I really doubt slicks would get me right to 12.9, but is this really the problem? I'm still following through with my goal of mid 12s by the end of summer. 12.5 is what I want. Could it be done with slicks, the 3500 stall and headers alone or do I need a new pully and have 12 or 14 psi?

I am really thinking about getting a small pully like right now.

You're gonna blow up another engine.

[Motorhead350]

You're gonna blow up another engine.

You mean fry more wires? Brain do you know why I'm doing 13.7 and not 12.9?

[RF Overlord]

I agree w/FordNut.

Dom, 12-14 lbs on a stock bottom end is asking for trouble, especially the way you drive (I mean no diss here, just stating fact ;) ). You also better have a DAMN good tune if you want to support that kind of boost.

Here's a couple of guesses: is your motor still running hot? That'll kill your ETs right there. Also, if the dyno shop that tuned your car isn't experienced at tuning this motor with a blower on it, that could be an issue as well.

Zack drove The Blackbird to a 13.2 with street tires and a stock Trilogy tune (9½ lbs boost), and he thought a good set of drag radials should get it into the 12s, so I see no reason you can't do the same.

[Motorhead350]

I know of a member on here who has 12psi or so on a stock engine and has done so for like 20,000 miles. No problems with him.

[Pops]

Dom looking at your 60 foot times show that you are spinning the tires. My 60 foot times last nite were 2.03 and that makes a lot of difference. You may need to go to someone else for a better tune. If I could have been there we might have had a very interesting race as the times are pretty close. Keep working in it and you will get there.

[Dragcity]

Yes, You need slicks. You need to launch really, really hard to keep up with the competition. The only way you will be able to launch hard is to have really hot slick stuck to the pavement. The higher stall converter will help also, but not without slicks.

That will lead you to your next battle.....broken parts.

[FordNut]

Practice, practice, practice.

I believe you should be able to get in the low-mid 13's.

[vkirkend]

Dom, What is the list of mods for the car? With just a turbo the 13's would sound about right....

[Breadfan]

I agree work on the 60ft, 2.1 is high, drag radials will help. Like john said you are spinning at the light too much. A smaller pulley and tune will give you more hp and exacerbate that problem - you need to get good at launching with your current hp level before looking to go higher. Based on what you've got, there is more potential in those times without getting more boost.

Also, just as you know someone with 12-14lbs and 20,000 miles on the motor I can find someone who ran 12-14lbs and blew it up. It's too complex an equation to think in terms of did it work for someone else, a lot of factors come into play including who does the dyno work.

Go for a low-buck drag radial solution on some crown vic or Mustang rims, and practice how the car launches with the addition of the procharger.

[Zack]

I ran 14lbs on a stock block once and made 520/465.
Never blew up

[DEFYANT]

Split the rims and get the Nittos. That'll fixer up.

Then you need to practice your launch. With street tires it can be done, but you have to be more conservative.

[magindat]

Shoot, even I've cut a 1.98 60 ft. Best ever. 20" SUV tires. Same ones I run every day. It was right when Greggash was teaching me to launch. I've never gotten that low again, but now you know it's possible. BTW, I'm NA, 3K stall, 4.10 and Art Carr L2. I out-launched a 5speed cobra with a JLT and tune that night. He about *****. Ran me down at 1000ft, though.

See I knew it! My mods are the Procharger, 4:10 gears, dyno tune, Zack control arms and thats it. I do not do burnouts anymore with the stock tires because I heard they actaully make less traction with a burnout. I need ti start a tire thread now because I am buying something tomorrow.

for those mods, it sounds like thats where you should be! No TC, no other bolt ons, and who knows if the tune is where it needs to be?

Factor in stock/street tires... I believe you did pretty damn good for what you got!

[Motorhead350]

Than why are all the supercharger companies saying their cars run 12.9 with no other mods? This thing took off less than a second off my e.t. :mad2:

[Breadfan]

Don't take this the wrong way, but you need some more practice. :)

Smokie did a 12.8 I belive with a stock trilogy and minor exhaust work, but stock gears/tc and intake. He was on street tires, he's very good at launching on street tires. I know there are others with centri kits that have run similar times on stock pullies/tunes of those systems as well.

Half of getting a good time is a the driver, the hardware gives you the means to get there, but requires a driver to get there.

[vkirkend]

And remember those times are the absolute best times that cars have run. I run mid 13's with a 500 hp truck and 4.56 gears but the 60 and 330 times are not great. Heck the 60 foot times between the 302 hp Marauder and the 500 hp SRT-10 is only 2 tenths. Remember "Spinning' ain't Winning". You need traction and a good launch to have good times.

[sailsmen]

In that air w/ a good driver 12.9-13.3.

U have not told us your launch, tires or psi. What junk was in your car? Was the track sticky or were people spinning.?

Your other time slips would help. Nittos will not stick in cold air.

Are you are a novice, get some runs in before u judge the car.

[Blackened300a]

Hey Dom, You were trying this at MV-V in the thick heat and you had wheel spin coming out the hole. I think tires and a hard launch will really help you.
My E.T's of 14.017@97 MPH in 87 degree's was corrected to a 13.688@99mph in the right conditions. I really dont think a N/A car should be able to outrun with a S/Ced car. (not that Im complaining)
Something is up with your tune or your driving habits.

[CRUZTAKER]

Your 60 foots are horrible. ;)

Perhaps tires. I've hooked 1.69 with bald pirellis.

I have a set of them in 305 size if you want them.

[Pops]

He would not have a problem driving the car with the MT on it. We saw him race at MMV and can handle it. When he drove my car he went straight as can be. I was behind him in his car, it was tough getting beat by mine own ride!

[Motorhead350]

Ya John has a ton of more experience than me and he was running very close to the same time. I have had the car tuned since then, but I still think I need some type of hook up. What did you guys do to get into 12.9?

[MarauderBoy]

Dom, what track were you at?

[sailsmen]

Please answer our questions.

[fastcar]

I would be pissed, too, if I was running 13.74 on a SC.

Tell us how you leave the hole. Each time I mod my car, I have to change my launch technique in order to keep my 60ft time consistent.

Stock I could leave at 1700RPM

CAI: 1500RPM

Tune: 1200RPM

4.10s: 900RPM

Steeda UD: 800RPM

It's true, you REALLY need to get the launch down, to get a good time.

Are your tires spinning a lot?

I get my best times with JUST A LITTLE SQUEEL. If I spin them even a little, I feel the car lose it's bite, and I immediately lose 1/10-2/10s.

BUT, once you get this part down, it doesn't take a genius to keep the pedal down and hold the steering wheel straight. So, it's not rocket science.

AND, even if you stink out of the hole, you are probably losing at worse .20 seconds, which means your car is still only running 13.50s, which seems a little short.

Which leads me to my last idea: 3500 RPM PI torque converter. These things are taking .5-.7 seconds off of peoples ETs, so I am told. I bet this mod alone will have you toying with 12s, right there my friend.

Then the widened MM rims, with the Nitto 305 drag radials, and you ARE AS GOOD AS GOLD. My 2 cents.

fastcar:burnout:

[Bradley G]

I picked up .3 with drag radials, stock width .This was three Sunday's ago @ Greatlakes Dragaway . 13.4 @100 vs. 13.7@99 with a best of 1.8 sec. 60' it was 94* that day . Did two faster passes, than my old bosses 2002 Corvette. You need sticky tires and practice.

[Motorhead350]

I went to Da Grove/ Great Lakes Dragaway and I launch at 1,200 usually and get my best times when I baby it off the line. If I floor it I run 14.0. Believe me I know what I am doing. If I launch higher or floor it off the line it's all over the place.
