Hi,

I want to ask for some tips to race in the strip, been racing for a while but am seen many hybrids doing better times, but mine wont excape the 14 sec barrier. Is not wheel hopping just little spining at lunch (Street Tires Toyo Proxes 4 w/ 12psi). Am doing an avarage of .500/.510 at lunch with a two step setup in my P30 ecu. My car revs max 9k but always go for 8.7k rpms. My first 60' feets is always 2.4. Last run last night 14.7 at 94.32mph. Does this mean i need another driver? or just that the car is not sticking to the track?

 

a 2.4 60ft is BAD. Get some good drag radials bfgs or even slicks 22x8x13 and get the 60ft down and your ETs will drop ALOT

jdm itr? I would think it should be running faster also, depending on what your definition of stock is, you should post up the slip (all the numbers) I had a b18b1 with pr3 pistons pulling 2.3-2.2 on bridgestone potenza re-730's. anyways, was running 14.8 @ 94 with stock ls trans / cm flywheel, is your motor completely stock? no boltons? or do you mean no work internally.. also you might want to try to raise the tire pressure, i've read here that lowering the tire pressure can negatively affect your time, although i never messed with lowering my tire pressure, a lot of people do it every time, I think someone named racin skittle might have posted about it? forgot the exact username.. but it wouldn't be my suggestion to just throw slicks on it, thats like a "easy way out" .. "fix-all" for bad launches / drivers but definately the best thing to do would be just keep practicing

Yes, is a stock spec 98 type-r engine in a eg. stock as taken from japan and drop in PR. the only thing done to the engine is 3+ adj in the intake cam.

i will post my last slip on monday.

 

u need a better ecu and get some slcks

Must not be to "stock" if you're able to adjust the intake cam. I take it you put it on a dyno then?

 

That's a weak mph for spinn'n a 2.4....on a ITR motor.

 

should be in the 13 or 12

nope, just play with the cams first we went with the 3- intake, it suck, but after 6k rpms it was fast as hell but weak at 5k and lower. then change to 3+ and that's when the engine came to life. havent take it to the dyno yet.

Perhaps this is your answer then. Messing with cam gears without a dyno will most likely lead to a loss of power.

 

did you time the car after the cam gear adjustment?

yes i have and set the ignition to 20 grades. but i know i must go to a dyno soon to see in a real chart what's going on.

 

ya, ur 60fts suck...

I pulled 13.7s stock internalled GSR except for CTR cams, and all bolt ons. 1.89 60fts, nothing too special... All in a del sol too, kinda heavy.

 

Yeah your 60 ft time is pretty bad. Get a pair of Lenso and slicks. You should be netting at least mid 13 second timeslip with a jdm itr setup. You have LSD too, so getting traction with slicks for you shouldn't be a problem. You should probably set your cam timing back to specs. Or seriously get your car on a dyno and have it tuned.

 

Thank you all, ill try get my hands on some nice tires. and make it happend.

 

theres a bunch of reason why you could be:
1st. yes your 60' sucks... but dont go for slicks yet... you should be able to get a 2.2 on street tires just fine
2nd... why are you running 12psi in street tires? your killing you top end, that why you mph sucks... try around 20-25 psi
3rd... messing with your cam gears w/ out tuning probably isnt the best idea...you might have loss some power
4th... why are you using a p30 ecu? is it chiped? thats hurtin your power
5th.... what wheels are you running, if you have like 16s on or gsr rims or something really heavey like that, than your probably not to that bad... try some HX rims
6th.. why are you reving to 8.7? you probably are not making power over 8k. that could be hurting you as well

in my itr motor in my cx wiht heavey as jdm interior and street tires i ran a 13.5 at 103 (almost 104) w/ a 2.15 60'

what wheels are you runiing? i bet thats hurting you the most... also pump up that PSI

1- one time. i got 2.2 but just got 14.2 (the only time i have done it)
2- i will try to run with 25psi to see how that goes
3- well we just add the 3+ following a dyno test that some dude had done over the net and it seem that did the trick, but a dyno is a must to see if it right
4- i was using a p28 chipped, but it didnt had the knock sensor module, so i upgrade to a p30 chipped, we burn our own chips, tuning the gas mappings and the ecu setting for max output, but my civic hasnt been tuned yet at the dyno.
5- my wheel OEM honda civic si rims
6- i rev that high cause the setting above, the car still pull foward but since there's no dyno yet, you might be right.

i will take your advice and try them all, i hope my next post would be a positive one. thanks

 

i have a 97 spec ITR all stock but aem CAI and 2.5 exhaust with a es muffler. i ran at calif speedway in fontana cali. i ran a 14.6 the first time i ever raced at a strip. my reaction times and 60ft times blow, i dont know what they are off hand.

You might burn your own chips and all, but it doesn't sound like you know enough about tunning to be messing with things. The settings from one mans engine will NOT always be the same for yours. Even if he runs the same "mods" as you, every engine is different. What the *** dyno feels and what is reality are two different things.

Just because an ECU is set to rev to a certain point does not mean that the car is going to make power up to that point. My valvetrain is built to take 8,600rpms and I will tell you it felt like the car made power all the way there.... But once I was on the dyno I could see that it quit making power around 8k. So, no need to run the rpms that high in my case. I would be willing to bet your case is very similar and that your just making noise by spinning the engine that high.

Anyways, if you want the good results then its obvious to me what you need to do.

1). Quit making cam gear changes without a dyno. Set them back to 0.
2). Take your car to the dyno and tune it properly

Making guesses with half of the "chips" that are out there is a craps shoot. 9 out of 10 of them are worthless and will actually make less power.

 

i looked at my time slip last nite and my 60ft time was 2.5 haha

WOW, and i thought my worst when actually trying was horrible. (2.21)

14.6 @ 98 mph i couldnt hook the track sucked *** that day everyones times were horrible my buddy in his gsr hatch ran a 16.1 i dunno what his 60ft time was. what would you guys suggest ...learn how to drive? haha

my wheel setup is 16 inch rota slips with parada spec 2s they hook good on the street but the track they suck ***
