I was getting better and better results dropping the pressure low on my 255/50/16 bfgs but I only got down to 14psi and 1.83 60fts NA 1.75 60fts N2O out here in So. Cal. where traction is as rare as a rainy day. <img src="gr_images/icons/cool.gif" border="0">

What size DR? I run my 275/50/15's @ 12 psi, and know of racers that go lower than that. However, I wouldn't run 17" DR's that low.

We run the 16s on my wife's car at about 11-12 psi. They hook great and even wrinkle around the wheel. She's been a best at 1.59 60'.

Bob Cosby,
Was that pic of you launching your mustang at Byron Dragway in IL?? The pic looked alot like Byron, but I was just wondering. Also I was wondering if you heard that the track is also nicknamed the House of Hook <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" /> . I was there that day at Byron, what did you run again??

Yup....with low pressure, BFG's will most certainly wrinkle...
![](http://members.home.net/bobcosby/cobra/images/nicelaun.jpg)
...and will hook, too. I've gone 1.65 60 fts on them with a stock suspension, and have seen like-powered cars go low 1.6's, and with a good A4, even high 1.5's.
Don't be afraid to lower the pressure at the track!

I got best results at 22psi with my 255-50-16 BFG drag radials on my 98 Formula. Best 60ft was 1.81.

Hi Brian. Yes, that was the Byron NMRA race. I don't know what I ran on that pass, but my best pass of the weekend was a 12.30 @ ~110 mph (3500 lbs rules-mandated raceweight). My 60 ft times that day were in 1.68-1.70 range. I lost in the semi-finals to the eventual winner (Rich Groh).
At NMRA weight, I've actually done better at both St. Louis (WFC) where I went 1.66, and Atco where I went 1.67. Here's a pic from that Atco race that I scanned out of 5.0 & Super Ford Magazine - it really shows the potential of the DR's. I apologize in advance for the quality...the pic was rather small...

Reading the caption, you'll note a trashed an input shaft at that race, and another one at MIR (not Cecil as the mag says) a couple of weeks later. Input shafts with my car are a whole nuther story...LOL.
In non-NMRA trim...ie...200 lbs lighter...I've gone 1.65 and 1.66 (blew both runs though) at Englishtown.
Hope this answers your questions, and please pardon the 'mustang intrusion' on this thread.
