What size tires do i use for the right front, left front, back right and left?

[iceracer]

That might depend on the rules of the track you are running.

[zxtwou2]

good luck out there! i'll be hitting up 2 races in Cole's County..so maybe i'll see you!

[raider]

That might depend on the rules of the track you are running.
Tires must be stock DOT. 50 or 60 series (wider) No snow tires. Tires must have a 7" max.

[iceracer]

That's a good general rule, but track rules can vary. Some say all four have to be the same size. Others don't care if you mix. Some tracks are still using the old letter sizes, ie; F78 or equivelent. Most dirt tracks don't all "R" DOT tires while some asphalt tracks do. In most cases, each track makes there own rules.

[raider]

What is the widest tire I can fit on the stock 14 inch rim? Is the right front tire the only one i need to be wider?

[iceracer]

205 normally, you might go to 215. The stock rim is only 5.5" . Normally, yes, since the Rt Frt is doing the most work. Keep in mind that a wider tire is usuall taller if you use the same aspect ratio. With the restrictions most tracks put on it is difficult to come up with the right tire combination.
Why don't they just allow any size tire and wheel as long as it stays inside of the body work. That's what my ice racing club does.

[crazy34]

on my home track, i run a 205,55, 15on front and taller slicks on rear. our rules state that your 2 front tires have to match size and the 2 back have to. as well as you cant go below a 60 series tire unless factory. i run the widest i can on both front. trick is if you run oval is getting the inside tire to bite in corner since there is no weight on in when you turn. i run narrow tires in the rear to keep it loose. most of it depends on your driving style though. just got done with engine build couple days ago. pulled in, new rings and check everything internaly, and ready to pull out in 3 hours and 37 min. now if only the weekend would get here faster.

[raider]

Racing tomorrow due to rain on Friday.

[crazy34]

just finished my race tonight on the dirt track. took second in my heat due to an electrical issue. i think its either my throttle position sensor or my fuel pressure regulator. went out in feature, started 3rd row inside. the car was still down on power here and there. it would come and go...even with that i still worked my butt off and the car did as well for the season opener win

[gunman_sr5]

Now we gota get the little bugs out. Congrats again though Ed. Back to back wins! Last race of the season last year and the first race this season. Sounds like we are almost dialed in.

[raider]

track was too wet. :(

[crazy34]

our track was roupher then a corncob. but i have found out that these cars love rouph tracks. i can run threw pot holes, dips, ramps, and anything else that screws any other car. if i could get forward bite on a wet track, i would tear it up. out track tends to be dry though. especially since we run last.

[s/rdirttrack]

congrat's on the win ed....keep'm coming....

[crazy34]

rain out today unfortunaly......trying to figure out some issues with the car as is. i was in and out of power last weekend. figured that out. it was in the vct. it was sticking. now i got problems with start up and it bogs hard core off idle.....think i may have to retime it or i have a hole in the fuel line from the pump to the top of the tank possably

[crazy34]

just some food for thought for some. i am going to be having a second racecar (zx2) that will be race ready for the most part. i dont have a full time driver as of right now. if anyone will be in the area that i am in and is interested in a night of racing for the heck of it, pm me and let me know. might be able to set you up for a night of racing for not much money.

[raider]

Had a flat tire in the heat so I had to go through consolation. Finished sixth. Beat the two 5 speed zx2. Do you weld the diff?

[crazy34]

no welded diff or anything. won opening night. i unhooked the front sway and thats all i did suspention wise. aint tweaked on it much. handling awsome right now. hope to have the bugs out for today.

[raider]

car did ok but i have very little acceleration coming out of the corner. Car is the fastest on the turns and the 2nd half of the straight. I have a atx. How can i make it accelerate faster without putting a 5 speed in.

[gunman_sr5]

Surprised he didn't post these here. http://teamzx2.com/showthread.php?t=15621

Instead of the resistors like they say to use. Just cut the wire. thats how we are set up. http://teamzx2.com/showthread.php?t=335

get a powder UDP. it will help out a bit. Intake will help as well if your rules let you do it. If not make a keeman intake. Make sure the knock sensor is unhooked.

[raider]

I have a keman and also have that wire cut. I still have the a/c. Does anyone know the length of the belt with stock pulleys and no a/c? Also, how can i make my engine run cooler? It was 90 yesterday and the water was spraying out. I had my fan on the whole race.

[iceracer]

Just because the water was spraying out doesn't mean it was overheating. What was the coolant temp ?
A radiator from an ATX has slightly more capacity. The AC condenser is blocking airflow.
An underdrive pulley will slow down the water pump. Run water only,most tracks require that. Make sure the whole system is clean allowing for max circulation.
Do you still have the heater in the car ? It can be used as an auxilliary radiator.

[raider]

the AC condenser is off and the heater is gone. I run straight water. I'm the only atx at this track. I'm the fastest car around the corners and I have the most top end. My acceleration out of the corners is a liability.

I finished 8th in the feature and started 28th. Had to go through the consolation because my car didn't want to go full throttle. Fixed that but didn't have enough laps to catch the leaders in the feature. A s/r won the race :)

[iceracer]

Run a seperate transmission cooler. This will relieve the radiator from that duty.

[raider]

damn rain

[iceracer]

Yeah, rain outs are not fun.

[crazy34]

my cars been down with many issues lately. i have to put a new set of rod bearings in now plus figure out another problem. the car is harder then crap to start, once its starts, if you touch the gas it will die unless you let it sit and idle for abit, its dead on the low end of rpm, and theres just no power. i have replaced the tb & tps, coil, fuel pump, fuel delivery control moduler, cam sensor, retimes, changed vct, and computers.

[zxtwou2]

pull the vac line off the fuel pressure sensor ;)

[crazy34]

think i am going to

[gunman_sr5]

:facepalm:

[raider]

Let my dad race my car because most of the parts are his and he hit the wall in the heat race. Broke the radiator, PS, and the belt came off. I had a good bumper that was welded to the rest of the cage, so it could have been worse.
I ran the car in the consolation with no water and nothing turning the water pump and won that. Car never got hot. Went to the feature and ran one lap and took it off the track to get 35 dollars for starting.

[raider]

My frame is bent to hell and my right front is pushed back into the motor. That's nothing my wench can't fix.

[crazy34]

my car as seen a ton worse then that.....lmao

[gunman_sr5]

Hey raider. A good idea for the radiator in the future here. Don't put the upper brackets back on. This way the car can flex in an impact and just push the radiator over. Should save it next time. Its saved Ed several times.

[raider]

was leading my heat and then my radiator blew and the right front rim came off. I forgot to tighten the lug nuts before the heat.:pissednana: the radiator broke where the hose connects to it. I ran the 20 lap feature with no water and there were 6 cautions. Finished 11th out of 24. I had to put it drive instead of low.
I think my set up is now perfect. I have 195's in the front. 20 psi left and 25 psi right. I have 215 right rear with 25 psi and a 205 with 20 psi on the left rear.

[crazy34]

your set_up is alittle diffrent then mine, but if it works it works. best of luck

my track is a high bank 3/8 mile (always slick).

[crazy34]

bout the same as ours. i run 205-55-15s in front and taller slicks in rear for my tires....the rears i run about 50 psi in as well to keep it loose

I had slicks on the back at the beginning of the season and couldn't drive it as fast around the corners. But i'm not as good of a driver as you.
The drivers where we are from are getting mad because one guy always wins. He has a honda civic hatchback with over 200 hp. Damn acura motors. That guy laps the whole field every week. The guy in the civic last year won more races than anyone in america. Thats lates, sprints, e-mods, pure-stocks, and 4 cylinders.

[crazy34]

and if i had my car on top of its game, i bet i could run with him. we had an escort gt and a cav that had a ton of money in them and i would give them a handfull.

[raider]

I just got my diff welded and that made a hell of a difference.

[crazy34]

wish i could do that......if i did that with my set-up, i could probly pretty much flat foot it all the way around

[raider]

keeps the car from going up the race track when going around the corners.
The race track owner invited rwd 4 cylinders to race with us. They were little late models with 2.6 ford mustang engines. The honda guy out ran them.

[raider]

crazy34, that helped the car but when the track became slick it didn't want to turn.

[crazy34]

on a dryslick track i run 50 psi on the rear on tires with hardly no tread, 28-30 on the left front(as long as the corners aint really rouph), and about 20 on the right front. if you run "slicks" on high pressure in the rear, if you turn and burp the throttle comming into the corner, it should try to slide around for you were you just counter steer abit and get back in the gas some.
