My post was just a response to this. I haven't read the whole thread, but the guy that posted before you has an 06 AP2(his username). And then he thanked you for helping him choose, but your theory wasn't correct for him. I dont have any experience with the AP1 so

 

I agree, no one should make a decision like this from one source, thanks for the find.

This was a thread that I was apart of many months ago when it was in its early stages, however there is a second link floating around which is the original and there is some different discussions of whats going on there. Its interesting to hear peoples responses to that thread which sometimes can be just as helpful. There are a few smart people floating around.

I'm sorry you don't see my logic or the points I made. This doesn't mean someone else doesn't have this ability. I don't much care for being invalidated from you after spending so much time offering up my energy into the subject. What are you offering here other then some mixed up formulations of what someone else created. His information is really interesting and definetly a good solid basis at trying to figure this gearing thing out, but even he stated that its not 100% accurate and I myself don't understand the formulas he used to create the simulation, something he learned in school apparently. I offered a formula that anyone can use and understand to find their own answers.

 

my thoughts exactly.... i read the information but all i see is 4.44 is the best cause i said so. i still believe the 4.77's will pull ahead and stay ahead in a 1/4 race.

where did you get your information saying that the 4.77's are useless after first gear and actually are a disadvantage from 30mph....

 

yeah I feel bad about that, somewhere along this thread people weren't differentiating the two. So I provided more information to help the Ap2 guys and just any car in general. Thanks for you post.

 

Man I hope you aren't running 215's in the back... That pretty much kills any credibility for me. That and I have owned 4.44's in the past and use the 4.77 now.

BTW, someone asked for this earlier: http://www.turnzero.com/technical_resource...gear_calculator

 

That gear calculator is a fantastic tool and i use it as an important piece towards determining allot of what we have discussed here and in other threads.

You'll have to excuse my frustration, i'm getting pretty annoyed with certain people trying to discredit me that don't have a full understanding them selfs. Its pretty stupid. I'm not sure what the motive is.

So tell me how my choice in a 215 tire in the rear discredits me? and After all you have read if you have read anything? So I don't have to repeat myself to many times you can go to this thread and understand what the benifits are and what the thought process was that got me to making that decision before you jump to too many uninformed conclusions ok? I'm doing you a service here. Take advantage of it and maybe learn something if you open to such a concept

By the way I don't care what gear your running currently, but what I think is amusing is that you apparently made an error in choice the first time. How does it feel to make a mistake on such an expensive mod? I could have probably helped you before but too late now. learning by trial and error is expensive isn't it? There is a way that you could have figured out exactly what you were getting the first time. Are you a drag racer, street racer, X guy or just like the feeling of more tq multiplication a higher gear set provide?

 

lots of info

 

I agree with GBmurder13, I would think 4.77 would have a advantage until at least 90. The 4.77 should not only launch much faster but would pull even afer that. If 4.44 could catch up after 30 I don't think anyone would have ever even considered this mod. I have taken my car 4.10 to the track, I am purchasing 4.77's at the advice of HTG. He should know that's all he does. My2 cents.

 

I am not interested in starting or continuing an argument here buy I am curious why you feel that tire size assists your cause?

I am a total n00b at this gear stuff. I have started getting into tracking and Auto-x'ing my car a little bit and I think I can see where gears will help me out some. I am considering the 4.56's because of the loss of top speed with the 4.77's. I have gone well over 120 at a few of my track events.

I guess my question is why do you think that a 215 tire alters the gearing? I run 245's at the track... Am I hurting myself???

 

I think I found the answer to my question buried in one of the posts above.

It is not that s2000Junky think a narrower tire is better just that the better tire he found is only available in a 215 width...

I personally do not think that I would explore his "tire mod" with such a narrow tire. Even if it is stickier then an S02. Snap oversteer is VERY ugly. Especially since my suspension is setup to run with my wider-than-stock RA-1's.
