Quater mile expectations
Well i was just wanting to get you guys opinion on some 1/4 troubles.
Went to the track my 01 z06 2 days with the high hopes of busting the 12's. Well that got shot in the nuts big time. Car had a aftermarket shifter, not sure what kind, which feels real good for just cruising but under full throttle is extremely notchy and very hard to hang the gears. The best run i could get that night was a 13.8 at 107 mph 60s were 2.3. Now i know there is atleast another half second there just on shifting and getting the launch right. After reading just about every post that Ranger has wrote i feel i can do lots better with a proper launch and practice. But is still no where near the 12's and the trap speeds seem way off. Also the track is at approx 3800 ft in elevation and most people tell me that it is about .4-.6 secs slower then sealevel. That being said i just placed an order for LT headers, Vararam and a x- pipe, and going to get in tuned, just wondering what you guys would expect someone like ranger could run in the car with these mods. Thanks

At sea level your car with the mods will crack into the 11's with good air/driver.

Longtubes and what not will help your overall trap MPH but what you need to do is get some more seat time and practice your launch techniques... if your running 2.3's and you can get them down to even 1.9's.....1.8's and possibly high 1.7's are obtainable on the stock F1 supercar tires but with some practice 1.9's shouldnt be a problem. This alone will most likely net you over a full 1/2 second (probably closer to 6-7 tenths) and get you right at that 12 second door also if your having problems with your shifts and not optimizing those there is some more time to shave there, I would think with getting the most out of your set up by learning to drive the car to its max you will be well into the 12's with no mods.
Good Luck and keep practicing

Good advice, as always from robz and MVR 155.
I'd suggest making a spread sheet of altitude corrected ETs and Traps using the "stock/super stock" entry for Roswell (Div 4) on this NHRA Chart. That way you can get your bearings by comparing the times you're running to what normally achieved elsewhere in the country.
If you do that, keep in mind two points.
(1) You don't correct for the weather (DA). No one does that.
(2) Not many tracks in the country are at sea level. Your times would be corrected literally to sea level.
Once you internalize the ET conversion at 3700', you will be more comfortable with your performance.
Finally, I can't say it often enough. It's good to get your driving dialed-in before doing the mods. The driver-mod will produce better acceleration that a car with +50 rwhp without the driver-mod.

Surely the point for reference is what the cars at your track are running and by how much you are beating them (assuming you are). Having said that, I had a Z28 that would run 13.8 pretty much stock at sea level but it was an auto and that was rolling off the line and flooring it with 2.2s reaction. Are you sure you're not spinning the wheels too much on launch?

I also agree with seat time. Even thou my track is not at that elevation, I did manage to improve my 1/4 times just from seat time alone. When I started, I was running 13.5@111 (2.3-2.5 60's) and after some seat time my best pass so far has been 12.3@116 with no performance mods. All solely on driving skills (I too read all Rangers threads and posts). My 60 is a consistent 1.9-2.0 on Wide Ovals. I just recently installed a VR, and a dry NX 50hp shot and hope to be in the 11's next time at the track.
I'd give it more seat time before any mods. I went ahead and put the vr and dry shot because I'm no Ranger and I know thats as good as it gets for me. Good luck and hope you get your 12's soon.

Great advice from some great drivers. Seat time & maximizing the driver mod ALWAYS yields the greatest improvement in ET.
It kills me when guys throw tons of money into their cars for more horsepower only to STILL be going slower then stock cars....More horsepower= HARDER TO DRIVE!!! By that I mean achieve the outcome that power CAN yield.
I wish folks would not give up so easily on their existing set ups before they go increasing them, sometimes drastically. They should be SURE they're are at the max achievements for their power level based, on reported outcomes by other members here on the forum, before opting to go the route of more money & HP= better ET's. That's usually not what ends up happening....
Practice & seat time!!!

wGreat advice form everyone!! But the CAI and headers were already ordered. the headers were ordered more for a sound improvement then performance the stock TI are just a little on the quite side. But i know i need lots more pratice. And yes i know i am spinning bad off the line. But i am no stranger to the strip have over 600 passes between a solid axle stroked 2nd gen camaro (with a auto) and a GSXR-1000. So i know the technique just not in this car. The six speed and lack of 31 in MT slicks is what is getting me. But thanks for all of the advice off to the track this weekend for one last round before the header install. and by the way for those of you reading this Ranger's shifting drills WORK try them.

The CAI & headers will help somewhat, especially MPH & once the car gets moving. These are minor mods & won't hurt you at your current 60' capabilities or make it harder to 60'. Make sure you get a tune after those mods though to get their full benefit.
The mods I was referring to in my above post were along the lines of a cam, heads, Turbo or supercharger or gears...
