Wondering who has the quickest 00-01 auto...are mid 14s possible?

 

not without power adders or major tranny work. KevinG had the quickest i'm sure but he did a swap. Pmp-n8a prolly does now with that bad *** turbo setup. So as of now he might be capable of low 13's or high 12's. Good luck if your on a quest to beat that.

 

Nah im going to go the N/A route (unless nitrous enters my mind down the road; i still have to learn more) But with almost all the bolt ons: intake, pullies, exhaust, VB mod, grippier tires, lower car. What you think?

 

15.0-15.3

 

14s aint possible?

 

there are a few 4th gens with all bolt ons, ecu, basically every possible mod barely breaking 14.9's so its possible if you get absolutly perfect weather.

 

well i dunno if this means anything but I had a legitimate race with a GTP (someone timing and starting the race) and I beat the GTP. This guy told me he had a 14.7 the last time he was at the track so I was very impressed. Its not just his GTP though, almost all GTP's run mid 14's. So im guessing mine was somewhere in the high 14's...and it's completely stock. He told me he got a good start and brake torqued to about 1700 RPM's. I did too but only up to 1200 (barely). I was impressed. We raced until i got to 110. I don't know what he was at, but he was at my front wheel.

 

No not all gtp's run mid 14's. stock they run high 14's low 15's some might get mid 14's with perfect weather. If you have a 00-01 auto stock you won't beat a 15.6 at the track. Not flaming you just stating facts from all the others times on this site. Matt

 

Well thanks for bringing the thread back. By July my goal is to have the first 5th gen I30 N/A in the 14s

 

I had a "freak" timeslip of 15.2 (perfect weather, perfect 60ft) with just an intake... I've also ran bunch of 15.4s same day with a berk intake... got a Y pie since... hit 15.4 on a much hotter day (like 70 vs 50) waiting for cold weather to set in... around 15.0 would be niice

 

Well The best I could manage was a 15.5second run @88mph. Birmingham dragway. I still had the spare in and well pretty everthing. I beat the CRX in the other lane though.. Next time I go I'll take my backseat, spare and jack out. Maybe I'll manage a 15.3...I won't be to impressed though.

 

Just ran a 15.11@92.10 that would be it for this season see ya'll next year

 

Damn thats sweet! Any new mods? Weight reducers? My traps are really bad, even people running 15.5-15.7 have higher traps.

 

It'll be in the "timeslip" forum once it gets "moderated" .

I got a Y-pipe since my previous run of 15.2 but today I did three runs - two of about 15.2 and one of 15.1 and I was never that fast on average before the Y-pipe (about 15.4 average before...). I felt like I could do better since I clipped the rev-limiter during the run but I had to leave to go to work

I think my winter mod would be a VB reclibration... then hopefully very high 14s. And then "snif-snif... why does your car smell funny"

 

I've got a 2000SE,MT with a few Mod's and the best I could pull this past weekend at the track down in Ennis, Texas was a 14.88/60' 2.29. I guess expected more from the car after the mods but that was the best I ran. The rest were 15.001, 15.049, 15.047. I thought I was pretty consistant driving, and never got out of third gear. Trap speeds averaged about 94.4mph.

 

MT ?

 

Manual Tranny...Quick change of subject,,,I am curious for all of the other cars that are pulling all of these 14's down.. The 14 second car owners have you had the cars dynoed....If so what kind of HP ??Are you putting out ? I am curious(perhaps my power to weight formula is wrong) but I remember correctly you would almost need to be putting out almost 190 hp at the wheels to break 15 sec(based on the weight of a 2k maximas weight) .. Please do not misinterpret what I am saying and think I am flaming folks..But power to weight is a simple mathmatic formula and based on that it will give you an excellent gauge on what your car will run in the 1/8th or 1/4..I guess my age is showing as I have an old slide rule that slide over the calculation and it gives you the time your car will run..Old school... If interested I will put together a little chart and post..

 

See, this thread was about automatic transmission handicapped cars not 5 spd ones that is why I was kind of wondering why you decided to post your times here - for they look pretty impressive in our context but is not all that spectacular compared to other 5speeeds (as some of them run mid to low 14s)

On your topic here's a calculator I used:
http://www.smokemup.com/auto_math/hp_mph.php

My car weights 3380 with me in it so accordin to them it'll take 198 FW horsies to get a car of similar weight into 14s... doesn't seem true at all

 

Sorry, didnt mean to get into you guys forum. In response to your comment on calculations, unless the cars have been drastically reduced weight wise or the HP has been substantially increased, I would need to see the car run low 14's. Mathmatic's says you can only move a car weighing x amount so fast. Torque is what moves you and HP is how fast. I will hop out of your forum, once again my apologies.

 

One additional note, I noticed on the link this calculation is based on a rear wheel drive car at a 20% Drive terrain loss. With our cars being FWD I do not think we have that much of a power loss.

 

I think automatic maxima has about 25% drivetrain loss - manual probably more like 10%

I have seen stick maximas run deep in the 14s (going to the same track with Aaron(theblue) and Eric(eej) usually does it). If you look in timeslip forum you'll find more than one 5th gen running mid-low 14s with intake and a Y pipe.

I think the ET calculation is inherintly flawed - there's many variables involved (especially on launch) that's why trap speed is generally much bettter predictor of HP as it is less depndent on how you get out of the hole.

 

You are exactly correct. ET times are difficult to calculate HP. Look at a crotch rocket(Street bike). What do they run high 9's low 10's ? Trap speed is probably a better formula to utilize. It all boils down to power to weight ratio. X amount of power can move Y amount of weight only so fast. If you know the weight of the car, driver included, and the numbers the car dynoed on a dyno machine you can calculate exactly the times the car can possibly run. The times calculated would be if you drove the car perfectly i.e. stay within the peak torque range at all times, and had an perfect holeshot without spinning the tires.

 

25% is CRAZY. Is there any way to reduce this loss?

 

This is basically all of the transfer of horsepower through the tansmission and through the axle, etc..but automatic FWD car I would say is probably more along 16-18%. I am sure there is info out on the web about it. Try this web site and calculate using the first formula and then use the second using the infomation produced from the first. The second is the power to weight calculation. Please let me know your thoughts..http://tnmotorsports.com/dyno.htm

 

Well lets'see, here's my thinking:

Nissan claims 222hp out of a 5th gen at the crank and nobody disputed that so far.
a) People dyno around 185 stock with the manual (16% drivtrain loss)
b) I beleive that stock 5th gen auto will dyno at around 170 (people dyno 185 with all the bolt-ons) which is 23% drivtrain loss for an auto.

So ...

I got 227

 

Hehe, beleive the hype... ou stil got as much drivetrain loss

 

True, but you should be breakin into the 14s soon. Do high stall torque converters help decrease the HP loss?

 

Hopefully... but next year... it's snowing around here
I gotta do some research on high-stalll TCs... I didn't think anyone made them for out car. I ned to look at doing VB mod and going synthetic with tranny fluid... so many mods - so little money

 

your right if you look at autos they have around 23% drivetrain loss according to dynos. The 2k2 autos supposed to have 255 at the crank *cough yea right cough* and are dynoing around 195-198 from what I've seen. That equals to around 23% loss

now that sucks!
