Hey guys,

Well i got my street and occasional drag car(Built B18c5 type r) tuned and on 10 psi its running 350hp on a apexi FC. In a few weeks i am hoping to get to the track and run some 1/4 mile times, before i do that im hoping to run the boost up a little more to 18 psi, however i have very little traction in the first 2 gears already. Obviously with more power to the wheels its going to be virtually impossible to put down.

I want to avoid full on drag radials and was thinking of using semi slicks maybe something like R888's as they can be used in my daily drive too.

I was wondering what would help put the power down more efficeintly. Do i need:

Traction bars ( how useful would they be)
LSD? ( currently using the stock type r )
What tyres would you recommend

Any other way to put the power down? Your advice and experience on the issue would be appreciated.

Cheers

 

if u are going for more boost and u runing a s300 ecu u need the hondata boost by gear and some steet slick MT tires and ,traction bar and the most important some good suspention like jonaka or omni and if can drop some pound on the car and u will be good

 

Im in the same boat as you are. Not thread jacking but I am spinning first 2 gears like nuts on street tires and I have a 92 civic cx gutted with a i/h/e jdm h22a(no motor work). I would also like to see what other people are using to receive traction on the track and cutting down the 60 ft. I was planning to get some bfg drags, a full-racing traction bar, lighter racing seats, cf hood/trunk/spoiler.

 

hes using an apexi fc.. so no s300. for traction I would use some 24.5x8 slicks.. and make sure the rest of your suspention is up to par, bushings, traction bars, etc etc.

 

drive the car don't let the car drive you!

 

mickey thompson drag radials,or slicks and lsd
i do high 1.6 60 ft on open diff and 23 inch slicks...

 

Did yall not read the part where he said he didn't want to run drag radials? He wants tires for everyday driving. Buy you some azenis and learn to control the gas pedal, that's all you can do.

 

I'm not sure if the power fc has a pwm output for boost control but I'd look into it if I was you. You'll need some sort of boost by gear option to keep the boost low in first and second. More importantly since it's a c5 I assume you have the stock it'd trans. I would get a gear type LSD (quaife) and a lower final drive. Call Dave at Syncrotech to discuss your Final drive options. I hope that helps!

 

Traction bars really only keep the suspension from moving laterally. They will help keep
from upsetting the suspension. Weight over the tires will probably help you out the most. Nrg-tech sells traction bars with optional weight bar kits.

 

When you say a pwm for boost control I'm not sure what you mean, I can just run a boost controller right? It's running off the wastegate at the moment.

It's currently running running stock itr tranny and LSD. How will an aftermarket LSD such ad cusco or quaife help? Dnt know much about lsd's.

Thing is I need the best possible 1/4 mile times and traction seems to be a problem. I dnt want to go full out drag radials as it's a part street car. What's your experience with Toyo r888s?

 

I would recomend getting a boost controler that will alow a high low boost option or even better boost by gear. If i were u i would look into the Apexi avcr or the greedy spec b, also ask your tuner what he recomends. I would also look into the allignment of the car, that can have a major affect on traction. Traction bars, good suspension, poly bushings will all help with your traction issues. And get some slicks for the track! Its night and day compared to any street tire! The r888 are great for the streets not so much at the drag strip!

 

^^^ did you not just read that he was on wastegate... Buddy if your having traction issues and are only running wastegate pressure a multistage boost controller won't do **** until you go to make more power. R888's are made for roadrace/autocross not drag racing, though they have a big contact patch I'm sure the sidewall is very stiff. Buy a taller tire if your Looking to buy tires. I personally was looking @ some 225/55/15's for my street car, thats a pretty beefy tire. Now if your car is slammed out and got some stretched out rubberband tires on it you have no hope. An upgraded diff is just going to be more durable than the stock Honda unit that's made to handle 170whp.

 

oh sorry he said he was going to tune for more power!!! He can also put a smaller spring in the ****ing gate!

 

R888's are a road race tire

 

Yes but with the lighter spring he will essentially make less power assuming he doesnt have a boost controller as he hasnt said anything about one.

 

Sumbody lock this thread PLEASE!!!! Its pointless to drag race with out sum kinda slick or drag radial plain an simple.

 

^^^ If you aint got any decent advice then dont ask for the post to be locked.
I have gained some information off this post, so why lock?

Yes as i said above the car is currently running off the wastegate, however i will be running a boost controller. No other way to increase the boost with the APEXI FC so im thinking of maybe running an AVCR ( boost controller isnt a problem), unless you can advice a better boost controller. I used to have the AVCR on my impreza.

Im looking into getting some traction bars.

Im not sure if im going to go for an LSD, i dont really know much about them. Never needed to really. Will have to do some reading on 2 way 3 ways etc.

Anyway if slicks are the best way then i may just run them on the track and keep R888s for road use.

What slicks do you recommend?

 

Your Type R LSD is good enough for your power level and needs.

I tried to pm but its not working. I have a multistage boost controller for sale turboxs its new never mounted. I switched to hondata and Im running their solenoid. PM me if interested.

 

There is only so much that can be expected from a standard street tire. Drag radials can be a viable option for your traction woes. I personally run BFG's all summer on my GSR but can quickly switch off to my Falkens when i want to go on a road trip. For an around town car, the BFGs provide a good amount of sticking power yet are fairly drivable. I dont have an LSD and only have traction issues in the top of 1 and 2 on full load. I've learned to feather the accelerator to keep it 'under control'

 

so much bad information in this thread...

 

go ahead dude, please enlighten us . You are more than welcome to post your correct view. I take all information onboard and filter it myself by Reading up etc. I've just been off the modifying scene so long I'm pretty rusty,

 

the only way your going to put down 18 psi is with slicks, period. (first few gears)

10 psi you could probably make it work, keep in mind the drag strip is a lot more sticky than the street, i didnt have any trouble hooking 10 psi on street tires on the track.

your stock LSD is solid, dont change it, dont waste your money.
Traction bars are a huge +
as with polyurethane motor mount inserts.


pwm boost control is when you hook up a solenoid to your ecu, and can control the boost per gear,

so you can run 10 psi(assuming thats your spring) in first and second, then 18psi in third+

this will help you with you traction problems,

but your using an FC, so its not an option.

dont use any greddy or apexi **** like some people are recommending,

if your gonna change ecu's, get obd1 software.

the price of a multiple stage boost controller, is more expensive than changing ecu's AND getting pwm boost control.

another way of getting traction in those first few gears, is a heavier flywheel.

 

Listen toglove he knows what he's talking about.

Stock type r diff is fine..
Keep in mind that anything over 300+hp your gonna spin street tires no matter what..

What I would do is
boost by gear- get the smallest wastegate sping 5psi
if you can afford some slicks get some mh 24.5 and play around with the tire pressure.
Traction bars will help big time!!
Make sure you have decent suspension

idk I Im missing anything?? But let us know what you decide to do..

For now if you can't afford anything just feather the **** out of it.. To me street tires/drag radials are useless for the track.. Well maybe because the only track around my town is 2 hrs away. Lol
just work with whatchu got..
Hope this helps

 

We have been giving suggestions to his op, which says he isn't wanting to run drag radials abd said nothing about slicks. Did you not read that he is having traction problems with the power he is making on wastegate. Boost controller isn't going to do **** unless the spring is changed and then that's money for a controller or changing ems, which then means a retune on the new ems which is even more money. There are plenty of ways to out power down on street tires and drag radials you just have to be creative. People have ran 9's on the 235/60/15 drag radials, and power street cars back in the day ran 11.0's on bfg drag radials so it can be done without slicks. If your engiine management doesn't datalog then you are really just shooting in the dark. But just listen to glove, he knows what he is talking about and no one else does...

 

No offense to glove but, wtf does noone else knows anything mean. Is he the only person that ever boosted a honda?
