I think i maxed out the 996 abilities
Ok guys,
I forget which thread we were talking about 1/4 mile times and i even remember a few videos posted.. refresh me if you will...
I just returned from San Antonio Raceway for test and tune night....
best ET tonight.. 13.00 @111mph!! If i had a sticky tire Im sure to have pulled another 12.87 I dont think these cars have much more than this!
Fabspeed Comp box
Spintech Mufflers, high flo cats
ECU tune
Spec Stage 3 clutch
Extensive head port work. done during rebuild
RSS Underdrive.
I think the clutch makes a big difference.. I was able to leave at 4500 without slippage 1.90 60ft times.. could have been in the 1.70s with tire.
Although some hate drag racing, it is fun to really learn how your car can be driven.
Road courses are still my all time favorite

nice mph 111 is moving. What was your 1/8th mile mph. I am looking at mods over the winter, have not done a base line but would like a 110mph car (coming from a 125mph+ mustang) that also corners.

Hype,
Funny you asked that! I was with a buch of friends running 8 second bikes which just happened to be Mustang lovers and they were talking about torque, et, 1/8th mile blah blah blah.... you know.... the standard track night talk.
They were really impressed how this car has such strong "big end" pull. My 1/8th mile time was only 80mph. It felt like a 14 second pass, but we all know how hard 3rd to 4th gear pulls and the 1/8 comes at the shift into 3rd.
I trapped the 1/4 in 4th deep in the power band. I think on the highway a 125mph mustang would have problems from a 3rd gear roll race!
Most of the track junkies agreed. What a blast last night!

80mph makes sense as the 911 is a momemtum car (albeit powerful). Ususally you pick up 20-25mph from the 1/8 to the quarter. Makes sense too as the tq numbers are lower on a 911, hence getting off the line and the first 1/16 of a mile will not be as quick as once you are moving and the hp and dynamics deliver.
Nice running, I am looking to get my car to that level too with IDP Plenum, 200cell cats and a flash (or close to it, would live with 108+).
As far as keeping up on a roll I was trapping at 98mph in the 1/8th and running out of gear at 125 so I dont think any 111mph car would stand a chance from a 60mph roll - they were brutally quick in the light 92 mustang. But it would have been fun to try!

What can you tell us about the head work & rebuild? What tires & size are you running?

Ha Ha.. do you have a link or something for it?? i'd like to research it further.
I'll report back to you after the install! I have heard that with the throttle body being the old simple cable style, there should be a few from other cars that should "hot swap" right in. I cant find any resources to confirm, but do think that this is a possibility.
Head work, just like on any other race car helps with getting air in and out of the engine. since a motor is nothing more than a big air pump the more you get in can cause a bigger bang and the easier the exhaust can escape allows a smooth combustion cycle.
An old racer engine builder here in town that says he "no longer" builds engines agreed to do some extensive port work for some cash and beer. From what he told me, he estimated about 15% better airflow and thought he could get more out of the heads but was afriad to get too thin. He did say that if he could find a way to put a bigger valve and stiffer spring set, there could be about 60hp in the heads alone!!
Find a good port guy and see if he/she is willing to give it a shot. I took a gamble and won!
Im running 315/25/19 nitto envo. They hook up great on the street and the track was well prepped for bike night.

I've heard that there are plenty of machinists that do Porsche heads... Boost Logic here in Austin uses http://www.headgamesmotorworks.net/
and has an 1100hp 996 Mk2 turbo car. They swear by these guys for head worrk, but i could not afford it. From what was explained to me, These heads have plenty to grind and smooth away. it just depends how much time you can afford for him to sit on the bench.
For any of you guys getting close for a tear down or rebuild, do it!! this car is fast.

even more impressive you ran that mph and time DESPITE having 19 inch rims. i would think ith 18's you would pick up a tenth or two and some mph (especially in the 1/8th) and get your 12sec slip.
