Finally got a few runs under my belt and I'm slightly disappointed.

Car is an 88 CRX with a 97 JDM B18c (R), stock header, chipped p28, 2.5 in exhaust and an intake and that's about it for power. 4.7 final drive. Car weighs 2130 with me in it.

This is from Englishtown last night:

1st runRight lane) 85 degrees and high humidity

20psi on Dunlop FM901's

RT--->0.861
60---->2.277
1/4---->13.910

2nd run: (left lane) 83 degrees and humidity

16 psi on the tires

RT---->0.397
60----->2.463

MPH--->103.46

3rd run: (Right lane ) 83 degrees and humidity

RT--->0.214
60--->2.263
1/4--->14.325(missed 2nd gear and sloppy 3 to 4 shift)
MPH--->102.97

16 psi on the tires

RT---->0.059
60--->2.596

Any tips, pointers, advice, criticism is appreciated.

 

Dont worry so much about the reaction time, the clock doesnt start until u cross the line. Also playing with launching, with your weight and power band im guessing 4 grand would be perfect.

 

Work on that 60ft and you will be happy :0)

 

I'm having trouble keeping those tires from spinning, even with an LSD. My first run was the quickest and I kind of rolled off the line. I never launched any higher than 3k any run.

 

i usually dont blame tires for not-so-great 60fts, but, in a car THAT light with as much power as you have, you probably arent going to be able to pull much better than a 2.2 60ft (which isnt bad at all considering), unless you put something stickier up there. more practice and seat time will definetly have you running better times. try to scoop as set of drag radials or slicks, at least that way your practice will be worthwhile and not so random when the car spins or bogs hope that makes sense

also looks like you may have aired the tires down TOO much since your 60ft's got considerably worse after you dropped the pressure further. you lost 60ft time consistantly, that leads me to believe 16psi might be a lil less than optimum. just an observation

As far as a 2.2 being the best you can do, maybe in a heavier car but not yours... this guys wrong on that point.

The key is learning the car and do u have any form of a 2 step? My hatch with me in it weighs 2275 and i cut consistent 2.0s even hit a 1.8 miraculiously on AVS ES 100s. My best advice is practice.

 

what's he gonna 2-step at? 2000rpm? i wanna see vids or something of a 1.8 on regular tires. ive pulled 2.0s in a 3000 pound car on all season tires, but i had a bit of torque to work with while slipping the clutch. with hondas it just seems you are either going to spin hard, or bog hard...not much torque to work with. im just speaking from the experience i've seen. i have never seen a 1.8 in a light car on normal street tires. show me otherwise

 

my buddy pulled 1.9x 60's on his gsr hatchback. it was fully gutted and was cammed. ran 13.6 at 100-102 or something like that. dont remember the exact number

make sure when you role thru the water box, you do a burnout.. street tires really shouldnt be burnout too much but you got to get that water off the tires. get them to smoke abit to dry them off, and carry the burnout thru the lane as far as you can. this will help dry the tires and pick up VHT to get them nice and sticky

then work on your launchin techniques. different clutch let outs and such. dont drop pressure too much. keep your tire pressure up around 20-25 or w/e u run on the street. too little pressure will hurt your launch.

you should beable to creep out 1.9x 60 foot. that will get you deeper in the 13's for sure! and hit your shifts

what rpm are you trapping at with those 4.7 final drive gears? what size tires? seems like it would be a good combo for your setup with the right tire size

next on the list of your mods should be drag radials.

I went around the water box for each run and the tires are 195/50(?) on Konig heliums (15x6.5).

Crossing the line I was somewhere around 8k rpm in 4th gear.

 

u think drag racing aint easy? try pimpin

I didnt believe in it, but believe it or not a 2nd gear burn out did wonders for my times, i first applied a burn out in second and then i busted out taht 1.860ft.

Also for the none believers i ran the fasted time so far in my K20R swap in EG hatch 12.70@111 basically 12.6 on 195/50/15 AVS ES 100s. I ran the 1.8 at another track in NJ where the track conditions are heavily full of rubber as they never clean the track and just keep piling on the VHT over the old burned rubber. Thats partly how i pulled that time, but on that run i hit 12.8 because as i hit top of third i got a CEL which caused me to finish 12.8@102. When comparing the times to my 12.6 run and looking at the 330 and with the 60 fts in i should have finished the run with close to a 12.4

Which other track? Atco???

I do get a CEL for TPS sensor towards the end of my run and reset it after each run, but I didn't think that would have any effect on my time due to being WOT.

 

go around the box then, and do a dry burnout.. just a slight one. that should help out alot.

Yep atco is wherei busted out the 1.8. Such good traction i broke a axle by the wheel hop in second!

Yea i get teh high voltage TPS CEL during WOT in third, it makes me go instantly into limp mode where the car just feels like it falls on its face.

 

its funny how your first run is mostly your quickest et of them all.

Yea, Atco is much closer to me and I intend on making at least one trip there.

So the code 7 does affect performance? I didn't notice any considerable difference once the CEL comes on. How can you prevent it from happening?

 

It all depends on what your trying to accomplish. You can make consitant runs even spinning. If you want better e/t. You should go around the water. You want to your burnout on the dry concrete. actually try to do two burnouts. Don't forget to lower your tire pressue. Good luck.

 

i have the same tire Fm901 195/50/15 and i have a type r with the jdm b18c. Best time was 2.2 60" 14.1 100mph with 40 psi. Launching about 4-4.5 rpm.

 

how are you launching? rpm? dumping or easing the clutch? i think 20 psi on those tires is a good place to hang around.

 

+1 on the tire pressur being too low for a DOT tire. anything lower that 20-22 and you will actually cup the belts and only the outer portion of the tire will make contact. So a 195 tire become a split 25.

 

35-40 psi would be too high?

 

/\ yes, for drag racing. you air the tires down for a slightly improved contact patch and most importantly, a lil more sidewall flex

 

When i ran my time i had my AVS ES 100s down to 15psi.

 

agreed... i'd stick around 20-25psi for racing... to little will not help. to much makes them too hard to hook.

 

With your trap speeds, I would say "screw it" and borrow a buddy's slicks.

Go run some high-12's, low-13's.

&lt;-- I can't launch on street tires either. So when I'm on them, I just leave at idle. Look at my sig. That was leaving at idle (the 14.2 pass)

Good luck.
