Car goes slow, Dissapointing 1/4 mile times Options

[HyperDeathKill]

Auto, GT, 50k. Mid 17s with exhaust, intake, underdrive pulley, s-afc. MID 17s. Good lord. Other people say they hit low 16s bone stock, what could be wrong with my car? Where do I start? I'm going to check the compression, plugs, and then wires. Oil is good, anyone else got suggestions?

[97sccelica]

well for one, you have a vert.

the verts are a lot heavier do to the extra renforcement.

who tuned your safc?

also larger wheels tend to slowour cars down, but more so with the ST's

[yep]

damn, mid 17s... stock 14s should get you down to the 16s but i would think some of those other mods you have would cancel out the loss made by the 17" rims...

[HyperDeathKill]

I actually ran with my stock steeles, which were 5 lbs heavier. Only 15 in rims though.

[snadman]

Ishy. I'm afraid now to check my times. I think when I did the whole stopwatch routine we averaged out like 10 runs on this old abandoned road (and don't worry, it wasn't illegal as I asked if I could use the road for this purpose...they said yeah and they blocked off all roads coming to it for me) and yeah I got like 16.7. Not the best of accuracy but pretty close I'm sure. I got same mods cept no s-afc (but i do have retuned ecu) and no underdrive pulleys. So maybe it is because you have a vert?

[bonzaisushi]

my best run was a 17.5 with a .65 r/t and im stock other than my K&n drop in and i have a auto but then again im hatch

[yep]

convertables arent that much heavier than hatchs/coupes. i think its about 175 lbs. i dont think thats going to put you in the 17s though. im pretty sure that convertables and hatches/coupes put out the same power also. it may be different, or maybe im just thinking about the covertable version of a different car...

[Silver94CelicaOw...]

I tend to think it might be the more restrictive 4 speed automatic tranny to blame......i would think my 5spd. would probably lay down 16's on the 1/4 mile, especially if my shifting is quick and pretty well syncronized. Although something might need fine tuning in your engine, and it wouldnt hurt to check i suppose. I really pushed my car tonight and i was pretty impressed with how well it accelerated considering its mostly stock, especially after comparing it to driving that Z4 i drove yesterday....lol....holy crap.....but i mean celicas arent bure-blooded sports cars by any means, so dont expect any real great times, but if you push it just right, our GT's can feel pretty quick.

change fuel filter
pcv valve
clean throttle body
tighten throttle cable
advance timing
run higher octane
check distributor cap
rotor

you shouldn't have any problems at 50k miles, but who knows.

[H8DC3lica94]

i've hit high 14's and mid 15's seconds with my st coupe. But that was before i took out my CAI. i ran with 14inch stock ST tires in front. and 17inch rims in back. and lowered all 4's to the floor. And most my shifts were redline.

Whats the PCV valve? I'm ran the highest octane I could for the track (not race fuel but that's really not nessisary). I don't think I'm going to advance my timing, because I'm alreadying running lean with the s-afc, and I don't wanna pay to get it dynoed again quite yet. I already tightened my throttle cable, pretty happy where it is.

But I'll definitly do everything else

I'm going to go next week, I plan also to:

Switch back to my lighter, wider wheels.
Take out the backseat, maybe side seat + spare + jack.
Take out floor mats, and everything else I can.
Run 34 pressure in front, 44 in rear.
Go on a better track day, one that isn't so humid and hot.

I hope by losing this weight I can begin to compensate for the convertible top, and I should of ran with my new wheels instead of my stock steeles before. The tire pressure I hear is key to shaving off time, and the day I went lots of people said they the track conditions were much less than ideal.

[ghostdog]

bad track conditions can definetly screw up your times. I wouldn't be discouraged, but if it happens again maybe be a bit worried

the pcv valve releases excess gasses from the crankcase into the intake manifold. I don't see how a clogged one could add a second to your time but it doesn't hurt to make sure its all working ok.

[HyperDeathKill]

Checked my plugs today, the gap was huge. I'm getting new ones, and I'll be going to the track next week. I'll post my times from then. Wish me luck!

[ToYCeLi8]

I starting to have some problems with my car right now too. I started feeling a huge drop like 2 days ago. MY poor celi isnt picking up speed like it used to.

95 GT, 5spd, short shifter, intake, 2.25" piping, 154K miles

Today for example i know that when we have 2+ people in the car that they will make a big difference. BUT IT WAS JUST ME!!!! Thats how my car has been feeling the last couple of days. I double clutched to beat a red light (PROFESSIONAL DRIVER. KIDS DON'T TRY THIS AT HOME! lol) and it didnt pick up speed? Now what could be wrong with my car???

[snadman]

154k miles? lol that could be wrong. You're double clutching and performance driving a car that needs to be babied to keep surviving. I kill my car and its at 113k....mine prolly ownt even last til 125k....lol. Keep on double clutchin man...thats so fun! you should add 150shot of nitrous and see if that makes ur car die or not. At least it will be fast in the few seconds before you blow up. lol. Sorry I';m really loopy because of some medicationsions so im sorry

[HyperDeathKill]

Well I would suggest checking all the things that everyone here said to check.

I second that, there is nooooooooooooo way you got those times. Someone with a 3sgte swap would probably be in between 15 and 13, so how you could be down there with 105hp is just not possible, even with weight reduction, redlining, a cai that adds maybe 1hp, and stock rims, no way.

[XE_Nathaniel]

You think that slow? my convertible is bone stock automatic and when there is 4 people in it I think I run 25's.

wouldnt that be considered down shifting and dumping the clutch. I cant remember what double clutching is but i dont think it has anything to do with that.

i thought double clutching was only used with old cars that either have no syncos in their manual tranny's or very old and messed up ones.

and, that does sound like down shifting and dumping the clutch.

btw i 4th the comment on the 14's, unless you go to an 8th mile track

Bingo!

Well, I still would like to hear ToyCeli's concept of it, but as 97sccelica said, it was a method used in old car that didn't have syncros.

Double-clutching can be used in today's cars when down shifting to help prevent syncros wear-and-tear, BUT it has nothing to do with giving your car a jump when downshifting. Basically, double-clutching is pretty much pointless with modern cars.

a ride in your car when its done will be good enough for me.

[ToYCeLi8]

Ok sorry for taking so long to respond. I guess you guys are right that i did just down shift and dump the clutch. But i do know what double cluching is, I'm probably the best person that can do it from a majority of my friends. Besides that, i did know that most people do double clutch on turns, on the other hand i didnt know that it is mostly used on older cars. OH well thanx guys for informing me a little more.

I learn something new everyday.



DEUCE

[HyperDeathKill]

Bliping the throttle for turns is normally called heel-toe-shifting. You use your toe to break (because you are going around a turn), then whilst still breaking, you blip the throttle with your heel, clutch, gear and go.

Every real driver I know says that double clutching is one of the most basic techniques you should know. Although I do have some rice friends who double clutch while up-shifting (sigh)

QUOTE

go to neutral, blip the throttle, go into second.

That's double clutching all right. Except it's more like: Clutch, neutral, take foot off the clutch, blip the throttle, clutch, gear.

[HyperDeathKill]

Yea on old cars the synchros weren't as advanced, you always had to double clutch.

Unless you have a tranny that sounds like it's gonna DIE. I do it all the time to slow down without jerking around and to make it easier on the transmission. Oh well, it's not my cool racer technique of the week tho

Heh... I used to be able to barely hit 14's squeezin a 75 shot... and that's an after massive engine mods... so I highly doubt you can hit 14's... even 15's with just a CAI...heh

[Pvc99gT]

yea... 14's with a CAI... IMPOSSIBLE. maybe u meant 16, or 17? i just hope one day ill be able to be close to my friend's 12 second Grand Prix GTP (its automatic) but i would also like a million dollars and 20 girlfriends. but that, like a 14 second basically stock ST, is not gonna happen.

This is true, because each one demands more than the previous. It is a vicious circle my friends.

[GT4SUM]

I went racing again on the weekend, and was highly dissapointed. I kept screwing up my changes into second, my boost controller was dicking me around(would change its mind on how much boost it was gonna give me) and i kept getting too much wheelspin. Best time for the day was a 13.5 (my previous best is a 13.4) and most of my other runs were 13.6-13.7

[HyperDeathKill]

I could take ya.

[TigerWoodsJr]

Well...I don't know why you guys haven't asked...but what did you put down for 60' time and what were you trapping at?

I have to think that the auto tranny isn't helping you.


ROFL at the whole double clutching convo.

[HyperDeathKill]

2.465 s for 60'
79.51 for trip speed.

Oh and I ran again with a whole bunch of newer stuff, including a heade diffrent wheels and wires and plugs, and got only low 17s

Hey guys, I have pulled 14.33 on the 1/4 mile and I have the convertable with the turbo kit and with a slipping automatic tranny. Im hoping next weekIm swapping my tranny to a standard with a duel force clutch and hoping to get at least high 12's , but Im also doing port and polish etc.etc.etc.

[97sccelica]

[celica3sgte]

[97sccelica]

he has the burien turbo kit.

but i doubt that a tranny swap, port and polish and new clutch will drop your time into the 12's.

at 10psi, i dont doubt mid to high 14's, but when you start getting that fast, it gets harder and harder to shrink your times

How fast do u think an auto st hatchback with just the turbo kit will run? 15s?

[Pvc99gT]

holy crap, this thread still exists? and oh yea, i'm well on my way to the 20 girlfriends muwahahahaha. and i've decided i will need at least 20 million dollars.

"well homsar called and said he was a million ladies tall."

and i also dont see how a 5sp tranny and a dual friction clutch could shave off 2 seconds. cuz dude, that is a lot!
