traction problems
 

having problems getting traction...maybe too much power?... what type of lsd do you guys/gals recommend? running falken 615s 205/50/15 almost new.. car goes sideways when i hit anything over 6psi in 1st 2nd 3rd and 4th gear.. anyone have any recommendations???
thanks

You don't just need an LSD, you obviously need studded tires as well!

Just add about 500 lbs. of lead into your trunk. You might end up doing wheelies then!

Learn to drive... problem will be solved.

Just how much power are we talking here?

Wider tires???

sounds to me like someone is bragging

no bragging.. real problems...im thinking of going with a 1.5 way lsd...maybe bigger tires in the rear..
ps i know how to drive.. this is my first miata... but ive had many turbo cars and a few mustangs with about 400-500hp...

well it seems to me that high HP+lots of clutch=traction

have you driven the car when its not raining?

go take a video.i want to see some 4th gear spins.im running 5lbs and can only spin 1st and 2nd with 185 all weather tires.

hence my post above... there are guys running open diffs with 250+ HP and not spinning 4th unless they want to really bad. unless you've done some serious work you arn't telling us about I doubt you are making 250-300 hp on 6psi.

Unless you are running 2 spare tires in the rear I dont see how you can do what you claim.

FWIW, I've got a 4.10 RX7 rear and azenis, and it spins in 1st and second, but only in second if its below 50 or so. This is at 12psi.

I don't spin my ALL SEASON (MUD & SNOW) tires at 200rwhp. What the fuck do you guys do to have all these traction problems?! Are you all clutch dumping at 6k or something? Yes I can break it lose if I want it to....but I mean wtf?!

That aside: If you are dead set on an LSD the only type that will help is a clutch-type as a Torsen will not lock unless you're in a corner.

My RA-1 would spin in the rain when it was 5*C, 3rd gear. But they were nearly corded and rock hard.

Well yeah I can step out the rear in the rain in 3rd, that's not too hard.

First things first:

What type of diff. do you currently have? Size, type and final drive ratio.

If you have an open, you do realize that an LSD may not exactly solve your problems, but it will make your car fishtail even more?

What is your rear camber like?

What spring rates and shocks?

Exactly the point. The OP is an idiot trying to fix a traction problem with an LSD, when it is likely conditions, tires or a combination of both that are causing the problem. Either that or he has a slipping clutch and thinks it's his tires letting loose.

Jason, is this still your setup:
i have a 16g evo 3 turbo, 1.8l injectors, 255 fuel pump, fm single exhaust and off road pipe, 2.5" dp, fmu, ngk plugs, huge xs intercooler, customer 2" piping... megan manifold

Did you ever sort out your tuner issues and find a dyno to tune the thing?
If so, what kind of power are you running and how did you solve your boost issues: https://www.miataturbo.net/forums/showthread.php?t=6392

With the above setup, you're capable of 200rwhp at 10-12psi with a good tune on a NB. But if your tune is bad (as I suspect), you're probably down in the 150rwhp range. There is no way in hell that at 6psi driving in a straight line you're "spinning like crazy" in third and fourth on dry pavement with good tires. I might buy that you're getting a little squirly through second when really punching it... but come on dude, tell us the rest of the story.

I would venture a guess that if you're still on the stock clutch, that your traction problem is really your slipping and dying clutch. Let me guess: at about 4000rpm's with your foot to the floor, the engine races to redline and you don't go any faster?

Start with listing all of your mods... better yet, fill out your vbGarage and your signature with all that info. Where do you currently live and what's the road conditions and weather. New York, right? I hear it's about 20 degrees right now... might not be the best time to troubleshoot traction problems. What kind of tires are you running and what is their condition? How exactly are you driving when this happens? More info!

dammit sam, you're always thinkin about what you say and typin a lot and tryin to help people and shit. we were all having fun here.

Sorry, I next time, I'll just do this:
:bsflag:

That's the spirit...Welcome to the club!

Too much power.

:BSmeter:

This is what I think of someone spinning 4th at 6PSI...

:gay: Why talk BS like that?

All hail the mighty 6 lbs



This is going well... Brian is on the right track though. :bigtu:

Sounds exactly like a goofed up "modified" suspension if you ask me.

Agreed! That's like doin wheelies in your Miata :gtfo:

Exactly.

Maybe his camber is totally F'ed :skid:

Maybe he cut his springs.

No wai!

On my electric eBay supercharger I can boil 'em in fifth!

wtf

you guys are funny..hahhaha...didnt get to finish my post due to being at work and my break ending... i dont spin the tires in 4th until about 12psi... for suspension i have kyb agx...fm springs..racing beat front and rear lower control braces...fm butterfly and rails...fm full bushing kit...konig helium in gold with falken 615s 205 50 15.. camber clips.. im sure there is something else i havent mentioned... camber is near perfect
act 1.8 hd clutch.. 1.8 lightned flywheel..
ps yes it was cold.. but i had driven for about 15 miles on the highway.. the tires should have been hot by then..i hope...
the real problem is that now that i have this power i cant really take off as fast as i want to...not that the car is out of control...its just i want to go faster...

More rubber. is the answer 225-50 >than 205-50 and better to.

Have you been just adding suspension stuff, or thought carefully about which parts will help in what areas? To me, it sounds like your suspension isn't very well balanced/tuned. With the chassis stiffening and harder bushings, you have to that much more careful about suspension design, as you don't have a flexible/floppy chassis to make up for suspension inconsistencies between corners of the car.

I haven't looked at it in a while, but you might want to check out the FCM suspension design spreadsheet that Shaikh has (from m.net). It's pretty good, and might help you find some trouble points of your suspension setup.

I'm running 215/45/15 Toyo T1-Ss near the end of their life, my only issue with traction is in 1st gear. I'll spin through the upper half of 1st only. Only mild tuning from FM's Link defaults, but the car ran quite well on them at 12 psi.

What have been the ambient temperatures when you've had traction problems? Tires have a hard time getting "hot," especially with low ambient temps. Besides that, higher treadwear tires such as traditional summer high-performance tires begin to harden at temperatures under ~40-deg F.

Also, "camber is near perfect"...what does that mean? What kind of alignment settings are you running? (numbers, please)

I had the same problem...Firestone tires and Stock Suspension....:)

Have you seen the fast and the furious, my miata hangs the wheels like that charger at 5 PSI, yo, but that's because I have a torsen, yo.

Livin' large at a 1/4 mile at a time, and yes, she runs 9's in palmdale, yo.

:td::td::td::td::td:

I can break my stock 01 loose in 1st or 2nd all day long. I do it instead of honking when someone irritates me on the road. car's ass just slowly slides sideways. and yes, it does require a few rpm.

maybe his rear shocks are set too stiff.

^We were talking about breaking em loose with just rolling on the gas.

to the OP, I still don't believe it, especially since now you've said you have an act HD, that would definitely be slipping well before you got to the power levels of spinning 3rd, much less 4th.

WTF are camber clips?

Yes, WTF are camber clips? Also, when you say your camber is "near perfect," what do you mean?

And, again, what kind of differential do you currently have?

well yeah I can go through all the gears in my altima spinning the tires if i want. I'm just saying, how the heck do you guys drive that you are losing traction so bad? If your dumping from 6k and cant hook up, dont do it.

Pictures? Id love to see some pics of the cars! :bowdown:

It was 20* here the other night and at 12psi ( 260+whp ) I spun 1st, 2nd, and 3rd. Unless its just SUPER cold where you are I dont see how you are spinning 4th.

Lol, i can spin first, and second if its really cold.

I remember right when i got my turbo in, it was about 5 deg. and i hit second and lit em up.

But lately its been warmer, and instead of spinning tires, i slip my clutch =(.

Oh well, haha.

Hmm, I only get traction problems in 2nd at 17-18 psi and then only when it is cold out. I just hit 5000 rpms and the tires go up in smoke. It's fun to buslength people while doing a rolling burnout, but I'd rather hook and go.

You know what I think... Your clutch is slipping: it smells bad and you aren't going anywhere, so you blamed the tyres! :gay:

'less it's got V-TEC yo! :D

I know that in the rain, with studded snow tires, I will semi-frequently inadvertently spin the tires just by rolling on the throttle in third. Thats only because studded tires are worthless in the rain.

Its a good thing the miata is such a well mannered easy to drive car.

I'd have to disagree about well mannered, it was a downpore one day and I was easing the throttle but also trying to get out of someone's way and spun it like a top down the road. fortunately it went straight and I regained control after sliding in beside a mail box on the shoulder. However with my new tires I can only get them to slip in wet weather while in reverse. On a stock miata that is.

I can break my tires loose in 4th gear on my other car. Its no problem really. Completely built drivetrain, and its only putting down 335 whp. So maybe its easier when your car is powered by BS?

:gay: This thread is great! :gay:

I would love to see a 4th gear spin@6psi! PLEASE post a video!

Why can't people leave vtec alone... my turbo beater has it... it helps me get good gas mileage :p

<-- closet honda addict.

it might have to do with the stigma surrounding it- like the cavalier I saw yesterday with a vtec decal across the windshied? :gay: I wished my engine was as capable. But then again it's way cheaper.

vtec isn't really costly... unless you go B/K/H series. The single cams are equivilant to our 1.6L mazda motors.

I have a picture somewhere of a bright yellow camaro with vtec stickers on it that I found in a Dennys parking lot.

It is sad but true... its on placed up there as some amazing power thing... when its really not.

Sigh ricers...

I know you love hondas and all splttime, but that pretty much sums up why i hate 'em, because of how stupid and moronic most of the people that own them are....not b/c they're bad cars.

I'm assuming 2L vtecs are the expensive ones. My 2L Mazda was ~$750. The F8 (the 1.8 version) was $250. I picked up a set of FE rods ($100) and an F2 crank ($25) that will bring that up to 2.2L. That's $375 for a beefy 2.2L dohc. - rob

My friend is doing a 2.2L sohc (f22a, accord motor) in his civic. Mated to a 1.6l trans. Should hold well over 300whp in completely stock form. Motor cost him maybe 200 bucks max?

Its all about picking the components... and for that motor... lots of custom work :p

its not that Hondas are bad, its that the community is 70% scammers and 25% retards.

I and my friends are happily in the other 5%. ;)

And... boy o boy did we take this thread off topic :p

To get back on topic... I have serious traction issues in my civic. One wheel peel hell all day long.

umm I think the pulling feeling hes talking about is either imagination, or maybe a broken diff arm/bad mount? could that cause what hes talking about?
