hey honda-tech, i just needed some input on how much quicker i can go based on my trap speed. heres a break down on my slip.

Reaction .7449
1/8 ET 8.39
1/4 ET 12.87
1/4 MPH 108.88

sorry my track doesnt have a 1/8 MPH nor 60ft times.

i know this is not very fast but i was just wondering how much quicker it may go with a 108 mph trap speed.

basic description of my car

98 civic hb
Stock B18B1 motor ARP head studs only
custom pieced turbo kit
cast iron manifold
turbonetics t3/t4 .48ar stg.2 wheel
2.5" downpipe
38mm wastegate
440cc precision injectors
s300
15-16 psi
slicks
weighs roughly 2400 with me in it.

thanks any input would be greatly appreciated.

 

What was your 60ft. Thats about right for the speed man. Back when i had my t25 setup on the Sentra i went 12.4@110mph with a 1.71 60ft on slicks.

 

dam, i had a b18b stock motor, t3/t4 ebay turbo dsm injectors at 10psi run 12.4@110 on 22" slicks

you can def hit 12.4 with that trap

 

15-16 psi in a slick what!! try bringing it down and launch harder. what do you have an lsd? sounds like you might be short shifting first and second. need more info what is you rev limit what trans what did the car put down hp.

 

thank you everyone for your input.

slicks had a tire pressure of 8 psi. im going to try lowering it down to 7 or 6 psi the next time i run down the raceway. boost pressure is around 15-16 psi.

i am running a stock LS transmission with a ACT 6 puck sprung clutch no LSD.

rev limit is at 7,200 rpm since the motor is stock.

unfortunately, there is no dyno where i live so i street tune my car and will have no idea how much horsepower or torque it puts down.

how much mph would i have to trap to get into the high 11s? lets say 11.9?

i have a friend that has the same car and it is a all motor B18C type r motor with high compression pistons and aggressive camshafts with a hytech side exit header and he just ran a 12.98 @ 101 mph.

 

11's would require about a 115-120mph trap and again at least a 1.7X 60ft

 

That MPH is good for low 12's. All you need is 110+ to get into the 11's but it will be hard. I ran consistent 12.0's at 115-118 on BFG's a few weeks ago and plan to go out this Saturday for a better E.T.

 

That's crazy no 60' times...

 

thank you that was good information

yes where i stay, there are very limited resources. No Dyno whatsoever. however i am glad that there is a raceway where i can have fun. the 60ft. use to work but i think the sensor is broken and its been months since its been last working.


do you guys go through the water box before burnout? what are the pros of doing this? are there any cons of not going through the water box?

 

try sourcing a GSR transmission if you can. I know it may be hard/expensive where you live but that would really help drop your times. also what size slicks are you running

 

lol that makes more since. like he said gsr trans and lsd or even just lsd. that way you can launch harder. i run 12.5's @ 106mph but i launch at about 7500 rpm with a stock ls bottom end rev it to 8000 rev limiter.

water box for the burn out i go to the end of it do a 3rd gear burn out with on lsd turn the wheel back and forth a little bit to try and keep both tires spinning.

 

I saw a car go 12.12 @ 108 so maybe low 12's are possible for ya.

 

completely stock b16/ gt30r @12psi
95 EG hatch, weight= 2390/me in it(street trim/full interior!)
100% stock b16 trans/ no lsd
24.5 M&H slicks @ 10psi cold(should have been lower. like 7-8psi warmed up lol)

here's my time slip(I'm on the left)

 

i went 12.65 @ 108mph w/ a 1.77 60' 225whp all motor gsr 22.5in slicks . see sig

 

I recommend you change the transmission its hurting you all the way around.

 

lol, ive been doing this a long time, hahaha right on the money, lol

All motor cars and turbo cars are a whole different group when it comes to how much power it takes to run a certain time but even then with both cars evenly setup to where one isnt spinning more than the other you should be able to run the same times with the same trap speeds.

A fellow SR20 forum member with his N/A 2.3L big bore, stock stroke SR20VE build is going 11.5-11.6@116-117 consistently n/a. That was with a 1.62 60ft. He has proper gearing for his power and all. He made 270whp,191wtq

I was going 11.1@132mph with a 1.78 60ft and spinning the crap out of the dried up old slicks i was using. That was with 461whp,391wtq. Notice the considerable difference in trap speed and only .4 faster time. A 132mph trap on a solid run with a high 1.6 low 1.7 60ft and not spinning till half of 3rd gear should be good for a 10.6-7 or so.

Thats just the way things go though.

 

i am running 24.5/7.0 on 13" exospeed rims

i would love to get a gsr transmission but that is considered RARE and high in demand if i do ever happen to find one. i am trying to make best with what i have.

so i guess based on my trap speed i should be able to do atleast 12.5 or just a little quicker.

thanks for the input everyone. anymore information will be greatly appreciated

 

Id go to a smaller slick if a different trans isnt available. Youre trapping 108 so whats is that with an LS tranny, top of 3rd,bottom of 4th gear?
Putting some 22' slicks is like doing the same thing as putting in a shorter final drive which I bet would really help your acceleration...
Good times btw!

 

im trapping 108mph bottom of 4th. i cant hold it in third gear as it will bump my rev limiter so i have to shift to 4th gear.

actually i do have some 22x9 slicks but do you think that will help with trapping higher mph and lowering my E.T.? the launch pad at my raceway is not that greatest. thats why i opted for a 24.5 but ill try installing my 22x9 and see how it does.

do you think 22x9 on 13x7.5 rims will clear a 98 honda civic hb?

 

I think it would clear as long as you dont have huge brakes or the car isnt slammed on the ground...
You prob wont see a significant improvement in mph cause your powers not increasing, but the et should drop since you essentially have better gearing with the shorter slick.
I think ideally you want to be crossing the line right a redline in 4th gear (unless you have super high hp where you need 5th).

 

yes my brake and suspension components are all oem.

so i hope it clears. i see what your trying to say. the smaller diameter of my wheels might give my car better gearing because of less rotational mass.

i hope the 9" wide slicks will help also with contact patch when i air it down.

 

Im sure the wider slicks wont hurt. Only issue I could see is potentially rubbing at lock to lock turns, but youll know if your turning too sharp...
The smaller overall diameter of the new slicks is whats gonna help you accelerate faster, not necessarily less rotational mass, but thats also gonna work in your favor...
Youll probably have to re-learn your launch technique with the new slicks, but I think itll help...
let us know your new times! Sucks you cant get your 60' times. Thats what really shows whats going on with your launches...
At 2400 lbs,slicks,and a good launch, at least 1.8 60 foots should be attainable. if your track had times...

 

yes i wish our track's 60ft. was working. that way ill know if my launch is consistent or not. i have a base it off of my 1/8 ET.

ill let you know if i get better times

thanks

 

smaller slick well help for sure and it should not rub anything i had a set of 24.5x9 on 13x7.5 lensos in a eg with no problems
