. I knew it would happen sooner or laterthey need to have a course for people who are new and explain Dont Drive Through The Water With Your Street Tires!!
if someone does it, we should be able to go up to their car and grab there head and bash it BAM!! right into the steering wheel.
i launch well there and always have unless some idiot in his 88 4 door accord drags a bucket full of water to the line...

The car makes good power, which I'm totally happy with, but I still think I could pull a good amount more out of it with stage 1.5 and a good tune. However, at this point I'm debating whether its even worth my time vs going directly with stage 2...

And about the ET Streets - yeah, I would like to get some of them, but I'm not sure where I can find some 15" wheels that will fit over my brembo rears (for cheap). My car isn't an all out drag car, and I figured I could use the ET radials on the streets as well when I feel like laying the smack down.

There are a few 16" slicks and cheater slicks (ET Street and similar tires) out there but they are only in a few select sizes. Hoosier has a 26x 9.50-16 cheater, a 28x10-16 slick. MT has a few, 10.5 and 11.5" widths in 26, 27, and 28" diameter ET Streets for 16" wheels, M&H has a 26x11.5 and 28x12.5 (I really liked my M&H slicks that I had back a couple years ago), etc. I don't imagine you'd want a 27 or 28" tire at your power level, unless you have something very specific you want to do with your gearing, like avoid shifting into 5th or something.

well. on a 26 inch slick, alberto and i are both having to shift into fifth right before the line. i just bought some new 28 inch slicks that i will be trying out really soon. on a 26 inch slick with 15 psi, 4th gear goes exactly 115.8 mph. i will soon know how much i picked up from the 28. if this doesnt work i am going to order 3.9 fd and just be deep into fifth ....

i think i am selling my et streets. they are a soft sidewall tire unlike the radials, so they will wrinkle and hook a little better. here is a pic of them, they are about 27" tall actually when mounted on an 8" wide wheel, which actually might help you if you mph a little more.

yeah i am saying that if the taller tire doesnt work like i want it to, then i am going to go another route and get the 3.9 FD and be deep into fifth.
i just got 28 inch slicks which should keep me in 4th through the traps. but going with a taller tire might slow down the car the rest of the way and/or hurt my 60 ft time. i will find out though soon...

Couple things can account for that. Tachs are almost always off by a little bit, sometimes more than a little bit - my tach in one of my cars shows that my stock rev limiter is at 6800. I put that car on a dyno or plug in an OBD2 reader and it's dead on at 6600rpm, even though my tach is reading 6800. Also when you cross the line and your trap speed on your slip says 115mph, you are going a few mph faster than 115mph. 115mph is the average of your speed over the last 60 feet of the 1/4 mile, you're probably going more like 118 (that's just a guesstimate, it could be calculated if you know the exact RPM you cross the finish line at). These numbers are dead on given the gearing, tire circumferance, and rpm, assuming I had the correct numbers in there for 350Z gearing.

that is theoritically, now i know i hit my rev limiter on one of my runs and never shifted and trapped 115.8. the reason for the difference is the weight of the car on the rims actually makes the diameter a bit smaller. 26 inch slicks are 25.9 inches tall, now i am 100% sure that my car trapped 116 pegging the rev limiter in 4th at 7200. i figure with the 28 inch slicks i should be able to get 8-9 more mph outta fourth gear
i figure that with the weight of the car it lowers the diameter about two inches total. thats about the numbers that fit into the the charts.
and yes alberto 27 inch slicks will give you enough for 4-5 more mph, but then in a few months you will be wanting more and buy new tires again. i will get a few runs on these and let you know what i think. i have to wait about a month to go cause i have sooooo much other stuff going on with my car that i cant afford to break anything

i didnt think that 1" was really that much of an increase, but good stuff. so then i would think you should be all set with just 28" tires audible, and not have to do the FD swap.
