why la, jus now i came back, driving on double lane road. only me the driver inside....using 5th gear with aircond on....max speed on flat road is 90kmh!!!!! :blink: i finish flooring the gas pedal already...still it was static at 90kmh! engine sound is not loud. jus like normal only...but it cant go any faster!

i ever ask my dad...why he hardly use the 5th gear when driving his company vannette...he told me...5th gear has no power at all. thats why he hardly uses the 5th gear even on straight road with my 120y and the vannette, when the a/c is on...<_<

but when the a/c is off, thats when speeding till 150kmh for my car is not a big deal! so i hardly uses a/c in highways...but this weekend im fetching a few ppl for long distance, so must switch on a/c...die la means whole way i can only drive 90kmh! :wacko:

so r u ppl facing this kind of problem too? :unsure:

dudez....the meter's gauges speed up to 160km/h if i'm not mistaken..

hence, 130/140 should be the max you can go on stock good condition basis....

but well.....nvr underestimate that A series engine under your hood..

with the right stuffs, and mods..you'll be able to do wonders with it...but of coz..parts and expertise are rare...

that's y i think dedicated forums like this..would do much help...

keep up the great job dudes..

i think he is using electronic ignition, his ECU got speed limiting properties

been 160km/h with old setup ..
just basic mod.

straight piping exhaust .. with stock 4-1 ext and one tabung. (PICK UP)
the jet of carb should be more bigger ..
last time i used twin solex mikuni and weber
for me .. thos monster carb not really eat your petrol much ..
get smaller jet and set a/f mixture .. the power of course not much la .. its ok oledi to get 160km/h
if you want more power ? get more bigger jet and set a/f more higher wwith open pod setup .. 4-2-1 ext sure can play top and pick up. ..

try hantam your car .. btw last time so berani .. that time no rpm meter .. i try my 4th gear til the engine smelly and til kenot go anymore, lastly put 5th gear .. damn cibetsia .. dropped from 160km/h slowly go for 130km/h

is it possible that i dont gain the same top speed like last time coz of my rims. was using 13-inch previously and was able to go up to 160. now with 14-inch its just 140. but dont think it can cause that much amount of difference with just 1-inch increase.... hmmmm...

maybe because of roling resistance.. what is the width of the new tyres? also 14" rims are heavier than 13"
