i realized i didn't post my times from memorial day weekend. many of you already know, but i should share with everyone :bubbrubb:
this was at the COTT race at SAR.
first pass: decent burnout, but the car kept loading up with fuel and stalling. finally got it to restart and ran
1.58 60' 6.94@100.11 10.88@125.10
a/f ratio was rich , don't know how rich because the wideband freaked from loading up on fuel.

second pass i added a little bit of timing, about 1.5 degrees across the board. a/f ratio was 9.5 around 4,800 rpm and increased to 9.7 by the end of the pass. not a good burnout and spun off the line.
1.72 7.08@101.37 10.97@126.3

third pass once again i didn't get a good burnout and spun off the line. i took out just a little fuel and i now had an a/f ratio of 9.9 through the traps.
1.75 7.08@101.8 10.95@126.6

i went out first round, but had a good time. i changed several small things over the winter and for the car to respond with these times on such a conservative tune(c-16 fuel on a weak tune) i was very pleased. i think the car had a 10.7x in it that day if i would have hooked. this was my first ever 10 second pass after trying for 7 years. :nuts: .my goal is still to run a 9.99 and i think it may be possible with more seat time and some tuning. i still have another pulley to up the boost if necessary and i can also take out some weight( currently 3290 with driver). only time will tell if i make it.

You using a t-brake? Drag Radials, ET Streets, or slicks? Suspension? MPH is good for some mid 10s if it hooks and cuts the kind of 60 ft that it should. You need to see a 1.48 or better and you'll see a 10.50-10.60 with that mph.

[gt350mustang]

i run on 275/60/15 et street radials. suspension is stock other than the ssm lower control arms. it will hook, but i need to practice getting a consistant burnout and work on tire pressure. i am leaving about 1,800 on the foot brake.

Congradulations on the 10s, the car has way more in it. Footbrake the car as high as you can without it creeping forward and get that C16 out of there and run straight 104 in it and I bet it picks up a ton.

Congrats on hitting the 10s, Joe!!!

I agree with the 104 comment. If you know your tune is rock-solid at 9.9 a/f the whole way through you're just burning $12/gal fuel for nothing. I'll bet using 104 in place of the C16 and getting a decent launch (higher RPM and no spinning) will put you in the low 10s with no other changes to the tune. You can then slowly sneak up on a low 11s a/f and get VERY close to your 9.999999999999999 goal.

If it turns out you need more boost to get 9s, you can put better gas in it at that time. But until then, you're only hurting performance and your wallet with C16 ;)

Major Congratulations! :thumbsup:

Tire pressure should be good around 11.5 psi when they are cold which will kick up to around 13-13.5 when heated up.
For burnout, spin them over a touch in the water box to get them wet, but not too much so you don't splash water up in the wheel wells. Pull about 6' in front of the box to make sure you are clear of all water. Spin them over in first for a second or two to get up into the rpms, then pull to 2nd and spin for another second or two until you see some smoke, then let off the brakes and slowly let off the gas as you start rolling forward. Do not dry hop.

At the start of the race day, I normally do a pretty long burnout to get lots of smoke and the rest of the day I cut it at little smoke (unless the track isn't hooking well for everyone).

For the launch, like said, bring it up hard on the footbrake. This will get better consistency on the lights. You can play with the rpms a little though if you are seeking more ET and sixty foot. Some cars like to be flashed and others like to be brought up on the brakes. Mine doesn't really flash very well, but it responds to the t-brake LOL.

Also, since you mention no other suspension mods, get you some 4 cylinder front springs and 70/30s or 90/10s. It will make a huge difference in weight transfer.

Another 10 second PoMoFo! Congrats!

Carl, you've never ran the MT Drag Radial so you don't know what pressures are good for what, especially since it's a different car than yours. Also, Joe knows how to do a burnout.

Fred, don't be an a$$. I was just giving some advice that could help Joe out. You're right, I've never ran on MT ET Street Radials, but I have ran on BFGs, nittos, ET Streets, ET Drags, and Hoosier QTPs. Every single tire that I have run on likes pressure in the 11.5-12.5 psi range when cold.

[Timebomb]

This isn't Joe's first rodeo. I've ran BFG's and Nittos and know that I could never run tire pressures as low as 11.5-12.5 psi...that is just asking for trouble on the big end. I'd tell Joe to start at about 15 psi and lower the pressure in half pound increments untill the 60' doesn't get any better or the car starts to move around on the top end.

[Blue91]

Funny Carl. I went 1.600 on Cristina's stock suspensioned AOD car with 19psi in the BFG DRs. My car went 1.500 with 18psi in the MT DRs.

Every car is different so to recommend to someone with a completely different setup than yours to run 11.5psi with a DR is just silly.

Some tires might only hook with 11.5psi, such as Nittos. They don't even come CLOSE to hooking like an MT DR so using that comparison is apples to oranges. It wouldn't surprise me if Joe can hook the car with 15psi minimum on a properly prepped track. If he has to go that low in pressure on that tire to get the car to hook, it's time to upgrade the suspension.

what's the advertised stall on your converter?

[gt350mustang]

what's the advertised stall on your converter?
should be around 3,200. it is a custom converter. my car has a difficult time not rolling the front tires during the burnout. not enough front brake pressure. add in that i don't go to the track much anymore and i simply need seat time to work out a good routine. these were simply test hits. nothing is close to optimized. i was thinking about how many passes i have made. probably 300 in just over ten years. i am still a rookie :racing:

LOL! I have made that in only a few months.

[Saleen91]

I think BigRed made that many passes on his last track outting!

For burnout, spin them over a touch in the water box to get them wet, but not too much so you don't splash water up in the wheel wells.

If the people putting the water down for the burnout box are doing their job right you should NEVER have to do this. They should have the water area wide enough where small tire cars (26" and 28" tall tires) is wide enough to where all you have to do is roll through it to cover the complete tire with water.

IMO spinning your tires in the water is taking a BIG risk, especially when your running a radial of ANY kind.

I've been doing this for years and never had a problem.

Spinning where it's a little damp is a lot different from spinning in standing water.

Too much water = http://videos.streetfire.net/video/0A879D55-779F-4E5A-B359-4D9420A746F0.htm
