Question,
Did anyone run their cars stock in 1/4 mile and then run it with just a popcharger (Stillen/JWT)? What kind of quatermile improvement did you get?

theblue

it will take about a second off of your time with better driving.

A full second off? That means I could be running 14s with just a popcharger?

theblue

you should be running low low 15s without it... this will just make it easier... I think you need to do some more research on driving styles for the 1/4 and you may be able to get you car into the 14s without anything. after the popcharger you should be able to get anywhere from 14.75-15.00 based on what I have seen most people do... but first you'll need to get some 2. 60' times

Well, I've only been to the track once. I had some flawless shifting with just minimal wheelspin. My rt was a bit weak, but I heard that it doesnt affect your time. I know that 99s are slower then other maximas, possibly why my time was a bit off.

theblue

give me all the info from your best couple of timeslips and DaveB and I (plus others) can analyze and see your potenetial. also tell us about how you launch and when you shifted in each gear. also give me the pressures you ran in each tire and what rims you have

JUDE

Ok, I have stock 16in SE rims, inflated at 32psi. I redlined 1st gear and shifted at around 6300 for 2nd & 3rd gear. Here are the totals from my best run

r/t - 1.162
60' - 2.382
1/8 - 10.244 @ 69.62mph
1000 - 13.295
1/4 - 15.869 @ 87.53mph.

So what do you think?

get that 60' down into the 2.2 range and you will be doing better. take about 10 lbs out of your tires (i run mine at 20psi at the track). take any extra crap out of your trunk. what RPM were you launching at. you said minimal wheelspin, but you 60' is pretty bad. that makes me think you are bogging badly. I've found a 3000 rpm clutch drop does pretty well, i net 2.2s every time with that setup, on slippery tracks even. what sort of shape is your clutch in...

your times and speeds are down from what they should be all across the board. it looks to me like you are not making the power you should be, or that you have an automatic, but i know thats not the case. it might take some investigating to get those times down, but we'll get em.

Well, I wasn't watching my rpms at launch. I was just kind of in tune with the engine sound. I don't think the clutch is slipping or anything like that. I only have 44k miles. I did not remove the spare or the jack and I could stand to lose about 70-80lbs myself. I'm thinking those were all factors in my slow time. I also need to work on my R/T. The guy I was racing had something like a .551 R/T (I think he was in the red 'cause he had no time) but I still caught up and smoked him. He was driving one of those old Volkswagen pickup trucks from the early 80s

theblue

ok... 22 lbs in the front (for you) and 35 in the rear... try launching at 2250 and drop the clutch and see if the car catches or just spins... if it bounces that's ok, if it spins thats too much, if it bogs then its too little.

take it all the way up to the redline in first (it's not harmful on these car, but I would not recommend that if it was a mustang) then take it most of the way up to the redline maybe shift at 6400-6300 in gears two in three.. don't use 4th gear. Also don't push the clutch all the way down, it will engauge at around half way or a little more so you can save times on your shifts by this. Activly think about the position of you hand on the shifter.. are you relaxed, or are you in an agressive mode - you will need to find a healthy compromise to get hte perfect shift. Anybody who shifts like they are driving normally won't get the best times because they are going for comfort over results.

take any extra weight out of your car... I ran my 14.5 with half a tank of gas, but I still took the spare out and the jack... it pays get anything possible out because ever .01 counts.

This is all I can think about right now... Any questions?

ok, i'm looking at one of my timeslips with just the popcharger mod.
RT -.870
60' -2.243
330' -6.197
1/8mi -9.469 @75.00mph
990' -12.214
1/4mi -14.691 @93.59mph
when i stage the car i focus on holding rpms at 1,500rpms. by the time i take off i probably launch more in the range of 2,100-2,500 rpms. i redline the 1st-2nd shift making sure to minimize the motions of the pedals and shifter. 2nd-3rd shift takes place at 6,200rpm. i don't shift into 4th. since my ypipe i've shaved more than a tenth off that time in that very same way. also, taking the backseats out, spare tire, jack, trunk liner, floormats, and front passenger seat can save over 100 pounds and takes 10 minutes. don't forget to run with your low fuel light on. the fuel saves the most weight of all. on all my runs my front tires were down to 18psi. there you go ladies and gentlemen, there are no more secrets to running 14.5 and probably faster with trap speeds in excess of 95mph on our cars with only bolt on's! have fun at the track! keep pushing the limits...

VQ: If I don't have atleast a 1/3 of a tank of gas then I hit the revlimiter in 3rd... don't you have this problem also (because you trap out 1mph higher than I do)

VQdriver

rev limiter? what rev limiter! i come very close to redline, in fact i think i am at indicated redline on the very top of 3rd gear with my tank almost empty and interior 3/4 gutted. maybe you do hit the rev limiter because you have a freer flowing exhaust? i dunno, but i haven't hit the rev limiter yet. i just come very close to it. anyway, going off the topic slightly, i would like a greddy exhaust! haha

theblue

The Greddy is no better than the Apexi... just save your money and get the Apexi WS for like 370

VQdriver

will the apex-i fit a 97 perfectly? will it clear the rear bumper flush? what about the rear O2 sensor? i want a nice super aggressive tone too. i thought greddy was the loudest. i rode in maximarider's 95, and i liked the sound a lot. i thought it could be louder/deeper. oh yea, i forgot to mention that i shift from 2nd-3rd gear at an indicated 6,200rpm. if you shift closer to redline maybe that is why you are hitting the rev limiter of your car.

theblue

I just don't have my rear O2 sensor in and that makes no difference really.... its been missing for the last 8 months. The exhaust is about flush or maybe tucked just a little. As for the sound - it all depends on your y-pipe... I have a loud y-pipe and now I can hear a loud muffler. Sure the Greddy is just a little louder but I would not want it any louder (its very loud).

Your 60 foot is going to have alot to do with how well your overall time will be. The better your take off the better your 60 foot. Sometimes getting the 60 time lower is better than the full 1/4 when starting to learn to drag.
