Twin Cam

13.01 @105.5 was my best so far, still need some more seat time.

93egSLEEPER

That's the neighborhood i should be in. Whats your car weigh?

Twin Cam

I wish i knew but probably around 2200 with me in it. Gonna try to find somewhere to weigh it soon.

93egSLEEPER

I'd like to get mine down to 2200 w/ driver as well. I'm running zero weight reduction at the moment. Full interior, all supports and a 50lb catback system. If I get my company truck for work soon I'll be putting it on a diet. Might even consider a tune on better fuel and adjusting cam timing to dial it in "track power" 13.4 for a car that makes 220whp on a stingy dyno is not up to par. Seat time and more tuning will get me where I want to be....I hope.

Great looking graph hoss. No midrange dip!

Nice et's too

blackeg

it was likely heat related id say. i wonder what your iat's were in the staging lanes. i wouldnt be surprised if it was heatsoaked and the ecu started adding fuel from the corrections. while your left coast has heat and drought it was barely 70 degrees and rainy here in ny yesterday. this **** needs to even out too many extremes. take the car out at night when its cooler and see if the afr changes. also try it with the slicks to see if they are able to load the motor more than the dyno changing the tune for whatever reason.

try bringing the slicks down to around 8-9 psi then doing a burnout probably 2nd gear. what trans do you have in there and what rpm did you cross the traps at? overall glad you got out to the track, im sure it felt good to be smashing the gas when the light turned green!

93egSLEEPER

Yea its been hot as **** here. The humidity has been no joke as well. I have a buddy who used to work at Endyn and he told me as hot as it was he wouldn't be surprised if I wasn't down 10-15% on my power minimum. I threw my laptop on the ecu after a pass and IAT's were 115-120 if I remember correctly. It was just running very very rich on top of that as well. If was idling pretty rough...it usually lopes but not that much. I already want to get out for another track day when it's cooler to see what happens.

I had the slicks at 8psi and I raised the pressure to see if I could get some spin out of the hole and didn't. I forgot to look at my RPM at the line, but I'm pretty sure its right around 7300. I'm running a JDM R tranny.

I wish I was better w/ the tuning side of things so i could try things out at the track.

93egSLEEPER

Here is the video to match the slip I posted. Slicks @ 12psi, 2nd gear burnout, launch @ 7300.

If you listen to the video close you can hear it pull 1st and 2nd pretty clean, third bogs some and 4th just sounds powerless.

If it was heat-related wouldn't it affect the car in every gear?

93egSLEEPER

It seems like the longer the gear the worse the AFR gets. I'm not sure why, but it a trend I've started to notice as of late. Not sure what would cause that to happen since it was tuned in 4th on the dyno. Off the dyno the car ripped through all the gears clean w/ no bogging feel. I put exhaust on it and thats when the issues started. I thought running it open would clear it up but it didnt. I looked at the AFR in 3rd and it was a steady 11.3-11.5 and when I hit 4th it was 10.5-10.8. 1st and 2nd are low 12's Only thing I can think of is fuel pressure isn't consistent causing fuel flow to change but very unlikely.

For reference this is my run:



DC2 @ approx 1900lbs
Stock B18C
22"
'96 Type R box
Exedy Twin + Insane Shafts @ 9000rpm launch lol - just playing around beating on everything

It took a few passes for me to work my way through the 13.0-13.5 barrier, I think I leaned the motor out enough to gain a few mph but I feel the biggest gain was seat time, nailing all the gears.



You'll get there eventually!

93egSLEEPER

Is that a 1.3 60'? LOL Jesus

Your car has a weight advantage- I hope to be able to do that same to mine soon.
I think 22" slicks may help a considerable amount, at least for the time being. I'll keep the 23's for future use if I need them. There is no reason I shouldn't be able to trap at least 105 w/ the power my car made...that's if the power is there and working correctly.

Thanks for the share. I'm motivated to make the changes and hit the track again as soon as it cools down some.

Andrew1706

Nah thats the reaction time, it was first round of qualifying and I was on a single pass so took my time

93egSLEEPER

Haha I gotcha. I was going to say...that is the fastest FWD NA 60' ever. Nice ET for a 1.9 60'

Andrew1706

Yea the light weight helps a lot on the stock motor, my season starts in about 4 months and I'm going 24.5" and 3 stages of nitrous.

My point was not to get so disappointed with how the car is performing after one meet, you can see from my 1st meet in that excel file that I was all over the place haha

Little did I know that I would eventually achieve my goal on 12 seconds!

It's all about seat time

93egSLEEPER

Thanks for the words. I know it has 12's in it without question. I just need to drive it more and keep working at it.

I get a quarterly bonus from work this month so I might spend it on a set of 22" slicks and tuning. Eventually I'd like to get a set of skinnies for the back. Not sure how effective they are on a build like mine though.

93ericSi

You gonna be testing the car at the track any time soon? I'll be at Pacific this Friday. Supposed to be much better weather for racing. Should get to see some fast times

93egSLEEPER

They have TNT this friday? Maybe I'll head out if the weather looks better. My tune is still shaky though. Need someone good w/ neptune to take a look at it for me.

93ericSi

Don't know anyone personally that's good with neptune. If the forecast holds look forward to seein ya up there. Always more fun when there is more than 1 honda.

93egSLEEPER

Yea I hear ya there. Do you know anyone who can look at a log and maybe make suggestions on a tune? I know how to use neptune, just don't know the ins and outs to the tuning and scaling yet. I think i was talking to you in the staging lanes at forum fest? Haha I'll see how the week plays out and hopefully I can head out. I'm hungry to get some cleaner passes in and see what it does in better weather. It would be sick to cut a 12 on the big tires and a half way decent tune. Hoping to have it on corn, re-tuned, on a diet and on smaller tires by the end of the month. I'd like to find a set of skinnies as well.

I'll see if my buddy can make it. He knows enough to help you out with the tuning and what to adjust where you need it. And I can see if there's any pointers I can give you from what's been working for me this year.

my best pass is a 12.99 @ 103 the week before Forum Fest. Made 207/138 when it was tuned back in '12.

Can honestly say seat time has been the biggest help.

93egSLEEPER

Solid time man. I hope to be knocking on that door very soon. I thought maybe I met you at forum fest...I was talking to a guy in the staging lanes in a teal hatch. He was boosted and running 11's though.

93ericSi

You got the power for it. And same size slicks as me. Should be achievable with good weather and some adjustments man. Look forward to seeing it

93egSLEEPER

What kind of 60's are you getting on the 23's? What does your car weigh?

43!

iTrader: (3)

What does it take for you to get into the 11.9999999 besides bad *** driving? I was under the impression that 250-260 whp and 2000-ish #'s + correct slicks and skills would get you there but now I'm starting to think I was dead wrong.
