SORRY!!!!!!! computer went haywire and I couldnt figure how to delete my extra posts!

[Captain Natro]

haha yer i was like... wtf y write it then edit the entire lot out lol

[Fryday13]

Yer my bad again!!!!!! but anyone know why mine seems to be a little more sluggish than the rest? would it be engine age or weight or something?

[mad082]

it's a NA gts4. anything over 170kmh in most NA low power, small displacement engined cars and they will take a while to accelerate. don't let the exagerted acceleration by people in here make you think your car is slower than what it should be.

I've hot around i'm guessing high 190 speeds in my N/A 5th gear just bogs out prob sitting around 5-6k

1st, 2nd, 3rd gear have "great" pickup but 4th, 5th just bog down

Did that make any sense

For the record i drive a s1 33 with a s2 engine

Right I hit the limiter, or at the very least there was a definite stop to acceleration and id been going up past my 180km/hr speedo for a bit. What exactly is the cut off speed? preety interested to find out how fast it worked out to be.

And after actually reading through the post ive now hit page 2 and realised the answer is within, thank you for your knowledge. I want to go faster but I dont want to cut the limiter and risk engine going bye bye. So i think Ill continue saving up for turbo and do it right

All jap cars are limited at 180KM/H

All jap cars are limited at 180KM/H

although speedo error usually makes it look closer to 190-200kmh on the speedo

[boiracer]

our old RB 30 powered Phatrol does almost 130 in third......why?? who knows. gearing is a funny art i will never understand. all i know is i like em short

[zebra]

My old falcon would do 100mph in 3rd at 5500rpm lol

My AU2 Auto would do 110km/h in 1st!

that's not that tall.

how many speed gearbox in the au? and what are you reving it to? father in laws AU only does about 70 in first (about the same as my vt. they'll both do about 120kmh in second.

or is the au a v8? they run a taller diff, but not that much taller (3.08 vs 3.23)

[zebra]

Was a 6cyl Auto with the 3.23:1 diff, running to 6k rpm

[mad082]

i think your speedo may be a fair bit out then. just checked the gear ratios and the max speed you should get out of it is about 90kmh (check my calculations against my commodore gearing and it was pretty much right).

[zebra]

they have a VERY long first gear in the AU's...unless it had the 2.92:1 diff ratio? XR6 autos had the 3.23:1 and the manuals 3.45:1

mind you this is going back many a beer now,

[mad082]

yeah my guess is that it had the taller diff ratio. puts it in persepctive for all the NA import fanbois who like to brag about beating commodores and falcons, when first gear is as tall as second gear in a skyline. try launching a skyline in 2nd gear and then see how it compares to the aussie cars.

Thats exactly it man, My auto NA 33 (dont flame, I know its not a rocket already lol) does about 60 in first, if i were to launch in second (which tops out at around 105 - 110) it would be a very slow embarrasing trip to 100kmph and would get beaten by bikes let alone an AU falcon .
