Tire Options for Force Induction

Going with the CES reinforced subframe and diff conversion.....my diffsonline 2.93 diff will be for sale shortly if interested!

[pbonsalb]

Last month we welded the adapter plate onto my subframe and put a 3.15 210mm diff into it. I may rebuild the diff to a 2.93 next winter.

Are you trying to stay in third gear in the 1/4 mile or get to 200 mph?

More for relaxed highway driving with the 5 speed and I don't think I would lose much on acceleration given the power level. I was at about 135 in the quarter at around 575 rwhp. Even with another 100 rwhp, I probably won't do much better than 140, so the 3.15 would just make it.

It is a 140 TW R compound, which is pretty aggressive. I put them AT LEAST right on par with a RS3/StarSpec, and so do most people who have tried them in my travels. They don't allow the RSR in enthusiast class of GTA because it is too sticky...the rs3 and star spec are allowed.

Like I said, not on par, but in the same league. Many time attack teams I work with use them for shake downs/experimenting before game time with hoosier r6. That says a lot to me.

Have you had a chance to run them? With a little heat, they are an incredible tire for the money.

Instructed in a car with them. They're definitely a 140 TW street tire. A 100 TW NT01 is another noticeable step up in grip.

Maybe they're a tiny tiny fraction faster than a Star Spec/RS3, but they're definitely comparable in that you're probably talking maybe a tenth or three per lap when the setup suits both tires, not 1 sec+ lap that you'll get with an R-comp.

Any interest in running a full slick on a 17" rim? Will definitely help save the drive line. http://www.mandhtires.com/M-H-Racema...0#.VSCQW5HD-Ba

Full slick woukd require front runners

[Butters Stoch]

Yeah, I wouldn't hit the streets with full slicks.

[turbo b]

wouldn't the race logic traction system help out?? if a person wasn't looking to run slicks

Race logic helps yes, but in the end your cutting power. OP has 800something powers. IMO race logic should only be used to save your ass in a corner. Other than that you really want to put the power down.

[turbo b]

the internet can be a painful place.. ive read that a few guys have gone faster with the race logic (one guy with a 300zx said he cut a whole second off his 1/4 time with it on)

in my situation I will street racing but staying on a street tire.. so theoretically with the race logic one would have a perfect lunch every time. you aint winning if you spinning but I just don't know..

[Butters Stoch]

Let's use 1/4 for instance. The key is to build a car with lots of power , and put the power down. This is done by suspension and proper tires. By using race logic in the 1/4 your cutting power to put it down when you should be increasing tire/suspension. Yes you might not spin, but your not putting down all your power.
A properly heated drag tire on a track will stick like glue, you will get full traction in first gear. Again.....a .properly sized, quality, heated drag tire. You need to do a long 2nd gear burnout till you see smoke. Then hold on.

traction control is a slippery slope. Like Butters said, its best to put the power down. I use it in my Megasquirt, so i can only comment on that, but if you have it setup correctly, it really does help.

For example, before i had the TC working, you would have to pedal the car. When you factor in human error, it sucks. You go no where. Doing nothing but playing with TC, i can now just leave the pedal to the floor (with in reason), and the system will progressively cut power to maintain or regain traction.

You combine that with a good tire, and it works very very well. But its basically just a bandaid for an overzealous driver/poor traction/car not setup properly.

[cj.surr]

You CAN accelerate quicker with a properly set up TC, though. There is a certain range of slip (5-10% depending) that you can achieve greater acceleration than full traction. However, the main advantage of traction control is that it is able to respond faster than your foot. The fact that it can keep it in that slip range is a bonus.

But I agree with butters, go with the best tire you can manage, and then go for traction control if it's not enough.

[Butters Stoch]

I would like a race logic for the street, but would shut it off at the track.

[cj.surr]

It will only help at the track, why would you turn it off?

[Butters Stoch]

It won't help at the track. It will limit the power. If your running drag radials and heat them properly, you WILL NOT spin.

[turbo b]

As for tire I'll be running an 255/40/17 nt05. My car never really had a traction problem but im downsizing in turbo (6266 t4 .81) adding meth a few other driveline goodies

as for the tc would help for the anticipation of the new found torque.. On the track I wouldn't use it but when street racing yes.

[dburt86]

typically speaking, you wouldnt ever really need it at the track with the right tire.

[cj.surr]

It won't help at the track. It will limit the power. If your running drag radials and heat them properly, you WILL NOT spin.

How will it limit power then? It doesn't do anything unless you spin.

[Butters Stoch]

To be honest, I would want to know if the tires are spinning. If they do , something isn't right. Either not hot enough, not big enough or suspension related.

Then if you were to run a full slick, those push you as they spin and find grip.

[chikinhed]

You can tell when Racelogic is doing its thing and then you just lift slightly until you can't feel the Racelogic. It trains you to adjust the throttle accordingly.

What sizes were you guys running with the Federals? I heard they run super wide. I wonder if the 255 would be an issue with stock wheels.

I run a 235/40/17 on my ti. My nitto's were the same size and didn't rub but with the federals they rub a bit.

I think this year however I'm going to get my first set of drag radials for when I want to do science experiments with locals. Spinning was fun for awhile but it's getting old.
