Will a set of drag radials help me out? See sig for mods. The reason I ask is that I was at Norwalk this past Wednesday night and I was dead hooking on GSC's with 23psi in them. With a stock converter I don't see how DR's can help if I get no wheel spin.

Also, does lower air pressure in the rear tires slow the car down as far as trap speeds are concerned? Thanks...

BTW, there was a guy there with a 98 black SS. It had a cam, headers, 150 shot of spray, MAFT, relocated battery, !seats, rollbar, etc. The only run I saw of his was a 11.1 at 121 or 126mph. I can't remember really. I know that I was very impressed though. Cool guy too. That's the first LS1 I've seen run anything less than 13's. I know, I need to get out more. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

You may want to try drag radials just for the insurance of the traction. Plus, they're designed to run with less than normal pressure. You may also want to try normal pressure with your standard radials. That should actually help traction more than lower pressure. It will also help stabilize the ride.

I'm wondering if Nittos will reduce my 60'. I think I need more mods to do that since I got so much traction I actually bogged on my first launch. Stability isn't an issue since I launch straight and it stays damn near perfectly straight.

Thanks for the reply. Anyone else?

If you are dead hooking on GSCs then a DR won't help. You only need a sticky tire if you are having traction problems.

I would try 32psi to start, if you hook leave it alone. Less pressure will cause more rolling resistance.

EDIT: It sounds like you need a converter <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

A converter would definitely kick *** but I am getting rid of this car soon. I'm getting something with an M6, probably a black WS6, so I don't want to dump too much money into this car. I would like to break 12's though. My best is 13.2. I'm not too far off. I think I'm lacking enough rwhp to jump into the 12's.

The only way a automatic like yours will run 111 mph with your mods is off a cliff. You sure you arent forgetting to post some mods? Like a 3100lb race weight or heads or gear or converter because A4's with your mods dont MPH 111. Unless the clock is way off...

What Minty Said. 318rwhp and an auto does not equal 111mph. Maybe with a 50mph tailwind. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

WOW! I didn't notice thoes trap speeds <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I only dynoed 315 hp, but I guess the converter was to blame for some of the hp loss. Please list the rest of your mods.

With that trap speed and 60 you should be in the 12.80s or 12.90s.

heck i run upper 11's on a 112 trap <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

with that mph you should really be better than a 13.2 <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

ive seen a bascially stock A4 formula go 109 with exhaust and lid once, but 111?? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

but those are M6 trap speeds.. if it were a 01-02 i wouldnt rule it out, but for 111 traps i would imagine the tires would be smoking off the line

if you're spinning nittos will help. Also you can try your stock tires and run 44PSI in the front ones to help your weight transfer/top end

111 IS POSSIBLE I DID 110 WITH NO ENGINE MODS!!! THATS A FACT

Hey Minty (and everyone else). I have the timeslip of my 111mph run, BUT when I got it I didn't even believe it. My best trap speeds, other than that, have been 105-106's. I created a post regarding the 111mph in this forum. I asked everyone if they thought it was right or not. I really question it, but everyone said just go with it. Unfortunately I didn't get a 60' or a 330' on the timeslip so I really can't judge it too well. Here are the numbers:

60' none
330' none
1/8 ET 8.645
1/8 MPH 84.28
1000' 11.169
1/4 ET 13.287
1/4 MPH 111.70

Here was my post:

https://ls1tech.com/ubb/cgi-bin/ulti...c;f=5;t=002357

I did feel that was my best run ever though. I do find it hard to believe that I ran 111mph without headers & a 'verter. I'm sure the 13.2 was right. I've run that about 10 times.

Here are all my performance mods:

hooker cat back
timing tricker
TB bump stop mod
!FRA
MTI LID
K&N filter
!MAF Screen
!spare/jack
HPP3
Fernco hose

No power adder, no heads/cam, no converter. Pretty much stock I guess.

That mph explains the 13.2-3's... I still think you could 60 a bit better with some practice on that track, since it's sticky. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
