First of all, I'm going to say this. Next time I go to the track I am;

-taking out the subwoofer box because after every launch it got thrown to the back of the trunk

and

-taking my cat-back off at the clamped area by my Y pipe because every time I launched, I disconnected my exhaust.

Now, for the actual racing...

I ran 4 times. I won every race. Here's a pic of my slips. I was car 131. I raced a Celica, another GTP, a Civic Si hatch, and a ricey little honda with an electric supercharger.




HOWEVER, in lue of all the awesomeness of racing for the first time, I forgot to scan on the first run.

On the second run, I remembered to set my gauges to record. I was seeing 12.8* of KR at the launch, dropping to 0 by 2nd gear and not seen again for the rest of the run.

My gauge reported around 235hp.

I think I may need to reset my PCM and relearn my fuel trims. Or, get a tuner and a laptop.

which is the slip agianst the other gtp? needless to say he must of not known how to launch and undoubtedly spun the tires to get a 16 sec et. either way good job and will you be going to GLD friday? i got my 3.2 pulley on so im ready to go.

Ah, you're already at the track? Little crazy.

Anyways, those 60' aren't hot, plus without a decent tune, you are losing more than you are gaining at the moment.

with all that work, you should be in the 13's, or close to it at least.

track prep is key my friend, pull the headlight, unload any extra weight, drop tire pressure in the fronts, and feather the throttle. you need 2.0 60 foot times, not 2.3, that's killing you.

EDIT - did you scan your LTFTs? i cant believe how much KR you were getting

I'd like to see other people's time slips. That track might have had bad prep.

I wonder if you're getting false knock.
Usually KR shows up at the top end of the shifts, not the launch.
Maybe something to do with losing your exhaust.

Look at his time slips..... Best 60' aside from his was 2.41..... Not a good sign.

IMO that track has some of the better track prep than any other track ive been to. i run 2.0 60's there all day. pb of 14.1 stock. GLD by far is my favorite track.

sorry for the small blurry pic but the stats are:
R/T____.369
60'____2.032
330____5.927
1/8____9.206
MPH____75.30
1000___12.019
1/4____14.403
MPH____94.91

This was a hot humid day. my line is on the left.

Maybe everyone running against him just sucks at driving

Hey, it's possible

It was 2 civics and a celica, cmon guys it's not like I was racing a Z28 Camero. Of course the other cars I raced were slow.

The GTP didn't have any mods except a stereo and lots of cool lighting. He also painted a lot of stuff.

I don't know anything on the Celica other than the guy was going "WTF?" when I blew past him down the line.

One Civic was my friend in his '02 Civic Si. He was running consistant 16's all night.

The other Civic was my friend with the most rictastic car their. Big fart can, very loud, and guess what else? ELECTRIC SUPERCHARGER!

I'm not saying I'm all that or anything, I'm just happy I won my races. I COULD have raced a red Nova with tires the size of a small child, or a turbo'd Hayabusa, but they were WAY out of my league.

But yeah, I'm wondering now too if it's false knock. On the top end I'm fine, it's launched and punching the gas that seems to throw the KR readings.

I've got my short trim and long trim on the same gauge right now so I'm going to read zuuls topic and see what they should be looking like. I've been seeing -2.3 on the long trim a lot though.

I think I need to get those trims in order with some casual driving before tomorrow night at the track.

And BTW, I had like 150 miles on the clock since the top-swap before I went to the track. Wouldn't that be enough?

In any case, I'm going to look at getting a tuner because I don't think I'm tuned for my cam and my fueling is probably way off.

Edit: Car 131 is me. Car 130 is Andy in the Civic Si. Car 102 was the Celica. 124 was the other GTP. Car 122 was rice boy.

-2.3 on LTFT's is not bad... That KR reading on launch is interesting. Did you pull the TC fuse?

Still for your mods I'd expect a bit faster than you have on your slips.

seriously tomarrow. go. i want a run with you

What's the TC fuse? Traction control? I left it on so I would have an easier time launching

Edit: Would I be better off with the power-tuner and go buy a laptop

or would this suffice

Oh lord, no, turn TCS off. It hurts you more than it helps you.

Your times are really off. You're running what I ran with my GT. It only had a u-bend delete.

Is there a way to download your scans? Have some folk take a look at it. Maybe hit up a dyno for an hour, spend $100, and it will be on a wideband setup.

if only there was a dyno around here...

http://www.scandepot.net/

upload your scans here.

also dont just turn TCS off pull the fuse. even if you just turn it off from the inside it will still retard timing. its a single 10a fuse in the engine bay. TCS actually hurts your launch it helps you in no way.

I'm sorry but you have got to have the record for the slowest top swap around and with an XP cam we're talking Guiness ,get your tuning down just do'nt run to the track ,I do'nt mean to be so critical but it just seems you're getting a way a head of your self .Chico (pops)

I tried not to be that harsh, lol. Definitely since I was the second to post!!!

Yeah you definitley need TCS off. It cuts power by dropping spark and fuel... very bad for your 60' time.

Three things

TCS off.
Purchase HP Tuner. It needs more fuel on the low end(?)
Get some practice in.

EDIT: Electric supercharger, eh? Um. which slip was that? When you debated its usefulness, what did he say? I imagine he feels a difference and believes it is more power. Its acutally losing power by reducing its vacuum pressure.

With a cam, he should be running rich. I'll let guys that have delt with it debate that though, just going off what drummerboy has told me about my car. I haven't gotten far enough to even worry about tuning my car yet.

Well, his is -2.5ish LTFT's, which is slightly rich, it's a pretty good number really. Some tuners are set on achieving 0 LTFT at WOT, but most see between -5 and 2 to be acceptable. But that is because ZZP tuned his PCM for the XP cam and the top swap.

I didn't have my PCM tuned until a couple weeks after I did my top swap and old cam, but during that time I did some scanning to see if it was knocking at all, and had -12.5 LTFT's at cruise and 980-990 O2's at WOT.

Better to be way rich than way lean, but way rich is still not good for the car. Now, with my XP cam (and I haven't done much tuning at all yet, just a bunch of scanning...) I'm actually running a bit lean (~900 mV O2's @ WOT)

I hope that helps you understand a little better Rook!

Doh!!!

Yup, that would be the cause of the significant timing reduction at the launch.

Fuse #28 under the hood.... I pull it every time just so I don't have to remember to turn TCS off every time I stage.
Sometimes I bark the tires on the 1-2 shift. If that happens and you have the TCS on you will lose even more time.
Yes, you will have to learn to launch, but hey! This is racing!

T/C off with street tires at full presure. I don't think its too bad. Oh yeah thats only with my intake and my D/P with 5* of KR. (Found out my car was runnin lean a few days after going to the track)

u had those times with just a u bend delete when i went i only ran a 15.0 with all my mods wats wrong!!!!????

He's got about 7 psi, you have 0. Something is def. not right with your car, though. My GT with just bolt-ons is a high 14's car @ 90-91. Of course, a tuner is the best mod money can buy, I found that out years ago after buying my PT.

i should get a tuner?!! with a gt

Well if you go as far as putting a cam in your GT, why would you not want to tune it? You don't tune just for power, you can also adjust your shift points, timing in cruise ranges (to increase MPG), do case learns, read/clear engine DTC's, scan the car, etc.

It really depends on how far you plan to take the car, and how long you plan to keep it. If you're gonna get rid of the GP in a year, then don't bother with a tuner (it'll take you that long just to get used to it). If you know you'll have this car for many years, then that $400 is nothing compared to what you get out of it.

thanks bad,
well to get down to it i will prob swap all my parts to a gtp at the end of next summer when i have more money and drop to like a 3.4 pulley with colder plugs and other various supoorting stuff but i do want my track times down for now what do you think i should do go to my engine shop that redid my motor and see if they can tune it more aggressive for the track?

You will NEED a scanner of some sort once you get some boost, to keep an eye on KR. If you put that 3.4" on the M90 once you have the L67 w/out the proper supporting mods, you're asking for trouble.

That all depends. What are your 60' times? Do you have any timeslips you could scan and post up? What is your track prep when you run?

i know all about scanning and KR but thats much later.....as for now i dont know were i put them but i ran a 2.1 60 ft and the track was very sticky as for air pressure at 25 pulled headlight and well thats bout it excpet the air wasnt perfect kind of hot and humid but still a 15.01? at like 93mph

Hello,

To add to the post above, I would like to point out that you may not have had "optimal" conditions. One time to the track is not a good way to determine what your car is capable of..... Through out a whole season, my ET's will go up and down pending on track prep and weather conditions by as much as a 1/2 a second. If you're interested in seeing improvements with minimal work, just keep your maintainence items clean and keep going to the track. Improve your driving skills, and you may eventually see as much as a 1/2 a second improvement.

That's why I was asking him about his 60' time, but 2.1 is really good for a GT. NA cars generally don't get 1.9-2.0 short times without lots of mods and/or drag radials/slicks. Just don't have the lowend TQ.

A 93 MPH trap is pretty good, trap speeds are a better indicator of power output than ET's. Did you happen to put your car on the scale at the track? My GT weighed in around 3400 lbs. w/spare & jack removed, GTP was over 3800 lbs.

Best way to make more power in your case is to tune. Add timing, lean out the 02's as much as possible (as long as you don't have KR), and make sure your LTFT's are locking 0 in PE. A set of S&S headers probably wouldn't hurt, either.

You'll be a lot happier once you get an L67 though. Had you put the same money into a supercharged engine, you'd be low 13's for sure.
