HP loss??

[Phoenix]

Hey guyz


maybe im imagening things ... but im not feeling the power in my car since i fitted the rimz!!

is it coz of the 19's?? :confused:

and what do i have to do to gain back the power loss??



PS: im afraid that my car will lose traction if i put back the 17's... so think of something else :)

well this matter of bigger rims is somethin i will never be able to figure .. some say bigger rims are bad for a start but good for top speed and vice versa ..

dont know for real .. i tried it myself and felt that smaller rims helps alot for a start and that was on a Cross engine car ..

not sure really but if u think it's coz of the wheels then u can always remove them and check :bigok:

They do drop 0-60 and 1/4 mile times...

But i wouldn't say loss of hp:nono:

[...SILVIA...]

when u fit bigger rimz,,it will effect ur car's performance 4 sure !

i remember,on my z32 TT , i had the original 16" rimz first, the car used to lunch great,and there's no traction in 1st gear and 2nd.
but after fitting the 18" rimz.,i lunch the car, and i can feel that it is much heavier,and that the differential can't move these big rimz as it used to do !

so,,bigger wheels,will always slow down the car ,bcuz of the bigger diameter,and the bcuz the rim it self is heavier !
and i think it makes a big difference !
i raced in the car b4,and lost to some car,and then raced the same car in the same time,with the smaller rimz,,and i passed it, so it makes a big difference !

its just physics !

:tongue:

With bigger wheels you need deeper axle ratio (numirecally higher) for example if you have 3.23 now with bigger rims you will surely need 3.42 or more (less pinion teeth) i dont know if there is any aftermarket axle ratios for Luminas. All the best & good luck

measure the diameter of the wheels and tires, see of there's a lot of difference, sometimes you feel the car is slower but its not..:confused:

Silver Arow.......Did you fix your problem? :bigok: if not

Did you re-program your computer after installing the new rims & tires hight.....?:D :grrrr: :devil:

I think its neccesary to finger your ECU :screwy: OTHER WISE
you wont get that wide open throttle madness:driving: :cheers:

if you didnt tune the ECU:bigok: i have doubt that your speedometer reads uncorrect
