Hmm, well, I dunno about all that. It just sounds like bad driving on your part and the guy who started this thread. If you're hitting 107mph, you should be getting anywhere from 12.6-12.8 with good-to-decent driving. I have a lot of track experience, but it didn't take 10 years to get good. My first 1/4-mile ever, I ran a 12.9 in a '90 Talon. I had done some 1/8-mile and 1000' stuff locally, but that was my first full 1/4. By the end of that day, I was down to 12.65. From that point forward, I consistently cut 1.6x 60' and was almost always hitting better 1/4-mile times than my MPH suggested. That guy you spoke of may be a great driver, but his getting a 13.6 shows right away that the track is not as bad as you say. It doesn't matter how good a driver he is at that point, because the car is only so fast in stock form. Your track may be a little slower on avg, but you and the thread originator should be be in the 12s, and he should not be hitting <100 mph.

Oh, and why are you set at 25psi on 91 octane? I wouldn't even do that on C16. The 16G isn't efficient at that psi, so you're actually losing power, unless you've tested it on a dyno to show otherwise. 20-21 psi is all you should do, unless you can get some race gas for the track, then maybe 22-23.

 

not that hard; just use the side of your right foot... the 6k doesn't have to be exact.

And you let the brakes off in #5; when you *hit* the gas, you just slide your right foot off the brake and jam it on the gas. You'll be surprised by the sensation; it's like you just can't get your foot off the clutch fast enough!

 

Heh, I dunno. After several hundred launches without braking, I don't think I'll start now. Heel-toe on a 6k launch? Wow, when did you ever get that idea? I actually prefer the car to start rolling forward so that it's not launching from a dead stop, but not far enough to trip the sensor (shallow stage).

What 60' times do you get?

 

I did not know you were missing gears? That makes a bigger difference than you think. A missed gear and a slow gear change will easily make you .5 seconds slower. Not trying to bust your chops, just tellin you from my 10 years track experience that hitting the gears is as important as leaving the line pretty much. You have lots of time to practice, so you'll get it down. I still remember how nervous I was the first time at the track with a manual. Just ignore the x-mas tree and relax. You can worry about beatin the other cars off the tree once you get the launch down. I would definitely say try again and see what you can muster up. Also, missing gears does effect trap speed. Good luck and go whoop some Cobra rear! By the way,I've heard that the track you raced at does suck for traction, but having a little spin off the line should make it a little easier to launch, so don't worry about traction too much.

 

No clue, going purely off my butt-dyno and the ratio of dust-ees to dust-ers.

Where did I get the idea? Simple. I thought to myself, "wouldn't it be nice if I could have my turbo spooled up and pumping air like the dickens *at launch time*?"

And I answered to myself, "Why, yes! Yes it would, at that!"
"Well, how shall we accomplish this wonderful feat?"
"Well, by getting the engine breathing heavily sooner!"
"What do you suggest? A porno?"
"Get your mind out of the gutter. Why not trick it into thinking it's already launching?'
"But, how, man? How!?"
"Put a load on it! Make it work, you dolt! Push it against its own brakes!"
"Don't call me a dolt. You're a dolt. You're mother's a dolt! And she wears army boots!"
"You freaking child! She's you're mother too! You're *me*, you schizoid freak!"

And so on...

(Welcome to my mind)

 

i may be a bad driver at 1/4 mile racing but my forte has always been top speed.

i only run 101 octane unleaded in the '03 & the small 16G is the one that has a threshold of 22-23psi. the big 16G holds fine at 24.5-25 psi with a shorter lifespan of course. i am waiting for the next dyno day to do some testing though. the closest track other than Firebird would be Speedworld. since their track is proven to be .5 sec faster than firebird, he's actually running a 13.57 & i'm running a 12.59. also keep in mind that this other guy who ran 13.6 stock DID NOT provide a timeslip to back his claim...

i'm sure it's possible to run faster or launch better & i'm not disagreeing with you on that, HOWEVER, the times you speak of have never been done here in PHX on stock turbos and/or stock clutches.

my track time & mods goes as follows: 08/28/04 i ran 14.46 @ 95 (catback,dp,filter). 03/11/05 i ran 13.62 @ 105.53 (base dynoflash tuned for 101 octane,MBC set to 24psi). 04/01/05 i had 2 runs. 13.81 @ 106.74 followed by 13.09 @ 107.02 (boost to 25psi,fuel pump,test pipe).

 

I got a 13.1@104 on my first try with the MR in stock form, but my 60' was nothing to write home about. I don't think I've _ever_ gotten a 1.92-sec 60' before today... =(

 

Nice time. Do you know what the density altitude was at the track? Do you know what altitude the track is? Was the 1.92 the 60ft. on the 13.1 run? If so, with a better launch you'll be 12's! Your all stock right?

 

I've never heard of density altitude, but the track is at 750ft above sea level. Yes, the horrible 1.92 60' was on the 13.1 run and should have been a 12.9x, but I screwed up somehow. Read the thread I created for more details and the timeslip. The launch was as perfect as any I've ever done, so the 1.92 60' is completely baffling. The only reasoning I can think was that I tripped the light by rolling forward slightly before dropping the hammer.

 

Does anyone here deep stage their car at the strip?

By the way, I would expect it's hotter in AZ than in DC/NoVA

Also, does brake boosting really help your times?
