ugh, well im a little tired of this learning to race a manual thing, but i seem to be getting better. still pulling mid 2.2x 60's mostly and low 14. here is the best slip.

Race weight: est 3000+/-50lbs
Temp..78*F
RH......29
Baro....29.96

60......2.269
330....6.017
660....9.118
MPH...78.01
1000..11.741
1/4....14.001
MPH...99.47

Best combined slip (best of every category)

60......2.222
330....6.017
660....9.118
MPH...80.09
1000..11.741
1/4....14.001
MPH...100.95

all passes done on stock 17's and stock potenzas, BC coilovers at full stiff, damn near no gas (DTE:27)

i know its got more in the tank, especially since i made a 100.95mph pass when the conditions were not too good (read 110*F track temp). shoot, even the 14.001 was at 78*.

overall im content, but i really wish i could get that 60' down and see some 13's...or go on a day that you can actually survive outside. i was putting watered down towels and stuff on my manifold in between rounds to try to cool it...could have really used some spacers.

 

Wow nice times man!! What are your mods?

Damn that sucks eh. I know when you run so close to the next time bracket (14.01), you just think if you had of done just a little better on the 60ft or just a little quicker shifting you would have broke into the 13's.

Nice time especially on the craptenzas.

 

oh yeah, lol. forgot to mention that. 2002 6spd mods as follows:
intake, 75mm MAF tube, SSIM, y-pipe, race pipe, 17* base timing, vafc-2 tune

non-power but race help: BC coilovers full stiff, free STS

 

Nice man. Have you considered headers? They are pricey, but that would definately get you into the 13's.

I got a question. The reason why 4th gens get such good gains with a y-pipe is because the y-pipe eliminates the pre cats, because there in the y-pipe, while 5-5.5 gens are in the exhaust manifold. Well people who do the 3.5 swap use 4th gen exhaust manifolds and 4g y-pipe, so why cant you 5.5gen guys swap 4th gen exhaust manifolds, and put a bolt in the egr hole, and get a 4th gen y-pipe?

Clearly i am basing this off of the best case scenario, im not sure if the 4th gen y-pipe would work because the layout may be different, i have really taken a look under my 2002 in awhile....gotta be months in fact, i just drive that car.

But if that worked, you could get a set of 4th gen exhaust manifolds for maybe 50$, and a y-pipe for 200, potentially have near the performance of a set of headers would?

Anyone chime in on this, sorry to ***** up your thread but i thoght id throw it out, maybe you could try it out or something.

Nice mods too, how do you like the 75mm MAF?

 

i consider them everyday, but as a college student they are too pricey. i dyno'd 235/229 which is what some have dyno'd with headers anyway. but yes, i REALLY wish i could get a set

if they fit, they would probly be worth gains, but the benefit to headers is the long, equal tube length. also the equal y-pipe length. two/three things that stock mani's dont offer. (actually the y-pipe is same length huh?)

i like it, i doubt its worth a lot of power, but i felt like there was a midrange difference. now that im tuned i get a z/g like sound for a bit of the powerband, so if nothing else its got that

 

yeah, well the y-pipe isnt equal length, the mainfolds i read are pretty equal length, its just the aftermarket y-pipes (minus stillen 1st gen) that arent. If you could get an equal length y-pipe made that would be pretty cool, gives you the nice sound as well as the gains of the y-pipe.

Id try this out on my 5.5 gen, but right now im having a hard time just driving it, stupid little problems keep arising on it.

 

Excellent runs.....more practice and perhaps tires and you'll get it....you're doing right by honing your driving skills rather than throwing more power adders on (though that wouldn't be the case if money were no object?)....Cut some 2.1s and you'll see 13's....


Jeremy

 

Thx man, no if money were no object i would get some tires and keep trying, then move up

 

sweet runs !! man im still trying to master launching myself .. the more you drag race the more conditions you are faced with. challenging to have the knowledge you need in any situation. (wet, dry, hot, cold, prepped, unprepped, tire pressure, water/no water) lol !

i need to catch up on your car, you got some power !!!

 

thx ceasar. yeah there is def a lot to it, im still at the tip. learning a lot though. the good news is i race in an import category and im typically the top5 fastest in the bracket so i dont get embarrased too much. at least its fun, and a 14.001 keeps me going back cause 13's are just a blink of an eye faster. literally. wish i was cutting 13.5x's like you though.

 

true, i guess i cant feel speed ? 14.0 and 13.5 feel the same or maybe im just used to the car now, but for sure the traction off the line plays a big role in making that perfect run, nailing the 60, going through all the gears at near perfect rpm range.

my last time out i had no idea what was going on. the track was unprepped and damp. now thats a mess ! lol

 

yeah, wet track sucks. i cant keep traction in 1st or second anywhere but the track, so i can imagine how annoying a wet track could be. hopefully ill be back with some better times next week. sub 100 temps could help

 

lol ceasars, you still learning to master launching? you are a great launcher. i should know i seen you race at the track so many times. if you still need to master launching, everyone else have a long, long way to go.

 

nice times and awesome traps man...

how the heck do you have a 3000lb race weight? that's like 450-500lbs of weight reduction assuming you weigh 150-200lbs.

 

nice run man! i know the feeling of bein at the edge of the next time bracket(14.06 @ 97.02mph; 60'=2.006) and im ONLY runnin headers, and on street tires also(general exclaims). ive got some GREAT hoosier qtp's sittin in my backyard waitng on the propper lugs so i can run them!!!!

GOOD LUCK ON THE 13's MAN!!!!!!

 

sorry, i meant the cars weight without me (160), so figure maybe 3150-3200 figuring the edmunds 3260 curb?

i have the following weight reduction:y-pipe, nothing whatsoever in trunk including sound deadening, removed plate behind backseat, straight pipe, coilovers, floor mats, trunk arms, spare tire jack tire and tools, 30lbs sound deadening removed inside car, back seat, pass seat, random brackets and bolts.

judging by the lighter.maxdes.net site its going for ~250lbs.

 

I still think you should dyno in 3rd (13sFTMFW)

 

I'm sorry man, you know me, I don't like 'est' weights. I need real data. Sorry. Still, nice trap, it reflects your DRF. BUT, I'm not being a *****, but you claim 235,...that was UNC, claim SAE. .. Or not. Do what you gotta do, but the fact remains, ...nice trap. ...

 

its from a combo of things i weighed and things i got from the site cause they were too light to weigh. (2lbs FTL). the heavier things(spare tire, seats, sound deadening, y-pipe, coilovers) are measurements i made. lighter things (trunk arms, straight pipe, floor mats, random brackets/bolts, backseat plate (pretty sure the plate weighed more than the 6lbs i used)). so there you have it. i would measure it all but it doesnt all fit on a scale very well. if you like, figure 3200 lbs, since thats over.

claiming SAE doesnt make sense for this type of thread. so what if i would have made 150hp on top of everest? i was racing at the same altitude (actually about +10ft from the dyno), pressure, and the dyno was at 85*F so i made 2 passes at dyno temp. what matters in racing is what power you make at the track, and those uncorrected numbers more closely compare than some standard conditions that someone dreamt up.

PS: i have never agreed with corrections, you make what you make. corrections are just for people who live at 6000ft and 100*F, with a pressure of 28.5 to not feel bad. unfortunately, you may make an SAE 275, but then go to the local 6000ft track and can even make a 14s pass....person is still disappointed as a result. see what im saying?


PSS: for those of you wondering, SAE was 229/219

 

Good runs man...keep it up and then here comes 13's!!!!

 

It does make me feel better. Sorry for bringing it up in your thread, but I'll keep it for the dyno forum (re: CF talk).


BTW, I'm @ 24.xx baro pressure (590 torr) I may hit the track soon. The dyno guy is convinced I'm a low 14 sec. car. Mile high FTL.

 

?!?!?! 24.xx is uber low. i was messing with DA yesterday and bumping my baro 1, up to 31, changed the DA from ~800 to ~200. a 6 pt drop...

 

I am heading to the track when the DA is most friendly. Then I'll post my times.

 

the standard barometric pressure/altitude relationship is 1in-Hg/1000'. 24.xx in-Hg is very normal for 6000' elevation.

you'll never see a barometer of 31.anything most likely - 30.6x is the highest I've ever seen since I've been paying attention to it for the last 5 years or so (I check surface prog charts every day for flying). a typical high pressure day is 30.20-30.30. 31.x "could" happen but it'd only happen in the winter, and I sincerely doubt that there has been a barometric pressure of 31.x in north america in the last 10 years. Sensitive altimeters on aircraft don't even have a setting about 31.00 usually because that type of pressure basically never happens. when it does, it's usually in siberia in the middle of winter when it's like -80 degrees out lol awesome DA - that actually happened in the 60s in siberia and the baro got up to like 32.02 and it was something stupid like -70 or -80 degrees F.

 

its been between 29.6 and 30.3(?) here for the last week. in fact, think that 29.96 was the lowest run pressure of the day, and it was also the coldest...go figure. high pressure and dryish (29%RH) FTW

 

yeah, it's 30.22 and mid 70s here right now which is great for august. heading to the track tonight to watch my buddy's turbo max run.

 

i guess its cooled off there huh? i have relatives that live outside of milwaukee and they say its been (1wk ago) really hot and muggy. even when it rains it doesnt cool off. i know youre on the other side of the lake but i figure the conditions are similar

 

Healthy trap speed. Get those 60' down and you're 13's for sure. Or give it a few more weeks till the temps drop

 

yea, any weight reduction?
