well, the other night i maxed out my basically stock 90 Rx-7 at close to 120!!! what the hell, in fourth gear. is something wrong. i got my 86 up to 130 and i shifted into 5th , not like i had much of anything in 5th but still. the S5 does have more hp, yet weighs a little more but should be able to pull off at least 120 right?? I dont know what to check of anything, any help would be appriciated.
Thanks

 

remember they are slower at night, and a S5 is 150-200 lbs heavier depending on model.

But you probably just need a tune up

 

Slower at night... I assume this is sarcasm.

Lower temps would = higher air density which would = more power.
Lower temps would = higher air desnity which would = more wind resistance.

I'd think at most these would balance out, but looking at my 1/4 mile logs, looks like lower temps = lower times which = faster theoretical (non-limited) speed.

I agree, tune-up.

 

Depends on the intake as to how it would offset.

 

Slower at night is true! With the headlights up there is more aerodynamic drag.

 

Nope, Aero drag and frontal area jumps up pretty high with the headlights up. .03 Cd increase as I recall

 

oh, and just the other day, i think some time after i pulled a 540 or during, my power steering belt snapped so im thinking about just taking my power steering out. any thoughts of why i should keep it in.............wait...i think its my power steering belt. pics will be up with arrows pointing because i can't explain worth a ****.
Thanks

 

just keep driving it. cut the belt off and keep driving it.

 

Is the s5 a gtus by any chance? Dont those have a different gear ratio making it top out sooner than others?

 

As far as I know, all n/a tranny's are the same. The t2's do have a lower gear ratio for acceleration.

 

my s4 tops at 125 down hill!!!!lol. id love to keep it in fourth but real scary to leave the revs that high......fifth is such a dog....... i hate it, thats when the competiton catches up to me

 

Ahhhhh, I forgot about that. Silly people with their silly pop-ups.

 

yeah, the rear end is a 4.30 as opposed to a 4.10.

 

where is the best place in KANSAS or MISSIOURI not to far away from southeast kansas to take my car and get a tune up. im not willing or have the time on my hands to start. also enclosed in this address is the thought to be power steering belt that broke. what is the other belt.
Thanks

 

the one you made out of red is for the a/c. Your green dotted one is the powersteering belt. Looks like ya lost ur a/c belt to me
