Well, My goal today was to crack the 12 sec barrier and I got damn close. I started out with a 12.33 @ 123.78 MPH and 17 runs later...all I could muster was a 12.10 @ 126.67 MPH. I hit 12.1's about ten times and noticed my average 60 foot time was 2.2 seconds. (not very good!) The zoomy trap speed of 126.67 MPH indicates that I can run a bit faster time ET if I could only get the tires to hook up a litter sooner! The weather today was 97 degrees and very humid. I did this on burned Michelin Pilot Sports and have no desire to set my car up to drag race. I suppose if I had some gummy Hoosiers with taller sidewalls on smaller diameter wheels...I'd hook better...(I have 993TT wheels 18" x 10" & 18" x 8") but hey...I had fun and didn't break anything. That's all that matters. (IMG:style_emoticons/default/rocking nana.gif)

That my friends is a FAST 914 (IMG:style_emoticons/default/clap56.gif)
2.2 60ft?? nothing but tire spin. Did you try and launch it in second gear? I raced a V8 911 that tripped the timers with 1.25's B |

It would *almost* carry the front wheels through the 60ft. timers.
I semi know suspension. Set the front Koni's on full hard and set the rears on full soft. Disconnect front sway bar and leave the rear in place. BFG Drag Radials. The only way to fly on the street!! Short dry hop to clean them (no water..drive around it) and launch it!! I bet your MPSC's did pretty well. B |

The 911 I drove had an all aluminum Donovan 400ci engine with alum heads and intake backed up with a 930 box.
I did most of my playing at a small 1/8th mile strip south of Ft. Worth Tx or at the Texas Motorplex south of Dallas. B |

500 HP @ crank...930 trans and there wasn't much tread to start with. They are on their last legs...so I decided to have fun at Rockfalls Racewayjust for fun...to see what this car will run a qtr mile in. If I went to 16" wheels with drag radials...my 60 foot time should come down alot...and oh...if the weather was cooler than 97 degrees...that would help a bit too. It should be a bit quicker i would imagine...

That is a mid 11s car with that kind of trap speed.
I went to the drag strip for the first time last weekend. DAMN what a rude awakening. Nothing at all like road racing except the exit to the return road. Sounds like you have plenty of potential. Yeah you should be able to nail something in the mid to high 1s for your 60ft times. You could pull 1.8-19 on street tires. |

With those tires and those conditions - man, that's really, really fast!
I don't think there are many, if any, street cars that could hit that time with those tires in 97 degree heat, including all of the big time big dollar supercars. Good job! |

B you want full soft on the front and enough rear dampening to keep from getting into axel hop. get the front up to get weight transfer to the rear with out sucking the rear wheels up into the wheel wells. |

I knew what I wanted (transfer) but couldnt recall which way I adjusted the 911 back 10+ years ago now.. (IMG:style_emoticons/default/biggrin.gif) It transfered well. I did adjust it the way I explained above. The Koni's where the rebound only setup and this is what worked the best. WE spent a lot of time getting it to "hook up" while I learned the BFG's.

Hey Brad,
I forgot to answer your question about trying a second gear start. The thought crossed my mind a few times at the strip and I cannot honestly say why I didn't give it a try. I would think the second gear in a 930 box would handle it fine....(I know for a fact that the second gear in a 915 WILL NOT handle it...I blew my old 915 2nd off the pinion shaft last year before going to a beefier 930 box. $$$$$$$$$$ |

I forgot you had the 930 box. It would have been tough to pull off in second.
I launched stockish mid 90's Trans Ams/Z28's with the 6 speeds in second with ease. They would blow the tires off if I didnt, but they had the super short 1st and 2nd gears. You had fun. That is all that matters. With those trap speeds, I would have to agree above about the car being a 11 second car. The 911 ended up running 10.90's with a little over 400hp. Took a while to get there. B |

Does anyone out there think I could improve my 1/4 mile times considerably with road racing rubber? I assume it would be way more effective than street tires. Here's the thing....I don't really want to waste any money on drag related stuff...I'd rather invest in some nice light race wheels and race rubber for the road course. That's really where my heart is. But on that occasional drag strip day....I'd assume the road race rubber would be much more effective than street tires?

I would get some sticky road race rubber but change the front wheels to skinny ones for drag day. Move everything you can over the rear suspension, Add some weights if you have to. The traction will make up for the 100 lbs. of traction. Make sure your calipers are in top condition so they are returning to full open and not dragging on the rotors. We used to swap out the disc brakes for drums and back them off for no contact. (pump...pump...PUMP!!! SH!T) (IMG:style_emoticons/default/ohmy.gif) front sway bar off, and the shck stuff "B" stated. Here's my old passion. 12:1 427, Crower solid lifter cam 510 lift 630 duration, BB Chev closed chamber rectangle port heads, Corvette 3X2 set up, 1050 CFM Fairbanks 10" converter gutted and modded Turbo 400, 4.56 12 bolt posi. W/solid bushings, Moroso drag coils, 90/10 front shocks, Never knew what my 60 foots were. This is before they recorded them. All I know is I would smoke 9" slicks and have to drive out of a slight drift, Bang 2nd and smoke em again. Never could get a hot launch. I needed to go to the next step and tub the car for real rubber but it was a daily driver. ET 11.72 @ 106 mph and Sandy would drive this to work sometimes on nice days.
