did i mention my engine had 200,000 miles. i was getting 2.1 60ft

 

news flash: R/T has nothing to do with ET.
you can sit on a green light for 10 seconds and run a 15.0. the clock doesnt start until you leave that staging line.

these R/T tips are not gonna help him run a faster time. thats a common misconception "MAN, YOU RAN THAT BADASS ET CAUSE OF THAT .001 REACTION TIME." you may have beat the guy you were racing, but you didnt make your ET any better...


do this: next time you're at the track, dont worry about the tree flashing down... just sit there and take as long as you need (without rolling forward) to get a good launch.

 

also: get those auxillary ports working... open aux ports + light flywheel = no launch.

auxillary ports being stuck open totally KILL your bottom end, and even made my car bog badly with the *stock* flywheel. i can only imagine what its doing to you with that light flywheel on there...

 

I never said anything about the R/T having anything to do with ET did I?

Did I say anywhere at anytime that these R/T tips will help him run a faster time?

So whats the problem?

 

I slip it at 4K with Kuhmo 712 and i get a 2.1-2.3 60' with a 9.8 at 75mph in the 1/8 mile with the mods listed below.

 

why does every drag racing thread have bad r/t's?
1st time i dragraced without any experence i cut 688's-564's.

 

The first thing you'll want to do is get a note book to record information on when you go to the track and keep your time slips. Most people dont do this, however it is a good idea. The reason for this is to record the weather conditions, tire pressure, and other various settings. When you do this the next time you go to the track you will not have to guess what your desired tire psi is or what your settings are in your car(this helps consistency). Also if your not confident about your launching technique find an empty parking lot at night and make a couple practice runs(i know its illegal but you do what you have to, to get better).

 

Good points Bruce, this should be done with any racing...notes are key. We'll be hush hush on the parking lot thing though .

 

The main thing that you want to worry about, is not letting the RPMs drop below about 4k. Our cars make no power below that point (relatively speaking). I always give a little slip of the clutch at about 5-5500 rpm. I get a chirp or two, and then Im off. This is with street tires inflated to correct PSI also.

 

bare with me, as ive never raced before, but i was wondering about how you launch. when you say slipping the clutch, thats just letting it out slow like you would do during normal driving right? and dropping it is letting it out all the way right away? i would think dropping it wouldnt make for a very smooth start at all, and possibly even stall. someone fill me in.

 

bump.

 

5 grand clutch slips for me, seems to work nicely

 

i don't get what dropping the clutch is..

is it..?

revving in neutral to ur desired rpm and then putting it in 1st?

 

dropping the clutch = waiting on the line for the light to turn green with your RPM's somewhere at like 7-8K (in 1st w/clutch to the floor) and a split sec b4 u see green just let it go. Correctly set-up the car will hook and book. Incorrectly set-up (for hard drag racing) the car will spin tires.

Slipping the clutch = same theory but ANY sign of wheel spin you play the clutch to avoid spinning the tires. You'll go nowhere fast with lots of wheel spin.

My 1st gen... I'd drop the clutch at 8K+ and the car would lift the front end, not off the ground but fenders would rise away from the tires. I was seeing 1.8 60's after heating up my Nitto drag radials... but keep in mind, dropping the clutch with sticky tires and a strong clutch breaks things... I've went through 2 rears and 2 trannies in one season.

 

I have 2 words for you. Power shift.

 

Dumping the clutch is where you have the clutch engaged, the trans in first, you rev to 4K, hold it there, and let the clutch out as fast as you can.

 

.724......my friends girl had a .6 rt

 

Isn't your car auto?

 

What happens if you rev all the way to 7k for each gear?

 

Drop the clutch @ the RPM point in which the engine does not bog, yet you aren't sitting and smoking the tires

 

I haven't read the whole thread but I wouldn't get an aluminum Flywheel, as I did In my previous setup.

 

sorry for being a newb...

but what's clutch slip and clutch drop? >.<

 

my only time at the track with the rx7, I ran a 16.3 I launched at around 3500rpm. The car is totally stock and even has a bit of an exhaust leak....I also had the worst worn bushings in the world at the time. I guess my rebuilt motor is running pretty strong??? And I also shifted at the buzzer.

 

I slip the clutch at 6500 (clutchmasters/ACT stage 3) and tend to shift at 7800 or right before the rev limiter kicks in. This was good for a 14.7 time with not alot of mods on my GTU....I will dig up my time slips once i unpack.

 

it helps if you read the thread, look up ^^^
