heya all
just went driving with a mates stocker VX V6 ecotec.. and well we were at the lights and he beat me by around 1 car length, i was literally shocked and had to pull over... wtf is going on with this world.. how come my car is so slow???? its got a 302 nice cam toploader, but it had 2.92's in it, so im guessing thats holding it back, getting the nine inch LSD stuck in with 3.5's so you rekkon i could gain even more than 1 car length to beat him? man thats crap (i dont have extractors) its been overbored .020" i think with new pistons i just cant believe that

tell me wots my weakest link? (and dont say my 302 lol)

More than likely it is the tall diff that isn't doing you any favours. When I Drag Raced my XB GT with a 2.75:1 diff (Old standard Engine) it pulled 15.8 @ 90 mph, compared to my EF XR6 which did 15.1 @ 89 mph. So as you can see, while the GT had more top end than the XR6, the 3.45:1 Diff got it off the line a hell of a lot quicker (probably a lot more than one car length off the line).

When I had the 2.75:1 Centre replaced with a 3.25:1, the Quarter Mile time dropped to 15.4 (still at 90 mph) so you can see the difference the change in diff ratio made.

i know the feeling of trying to race somebody with 2.92 diff gears and with a manual,
if you want it to be quick drop in a set of 3.5's i looked around for a borgwarner diff out of a ute, just to try the ratio's, or just go and get a set of 3.9's for your 9inch, it will scream at 100k/h but it will get there very fast and no doubt leave most your other cars back at the set of lights. how hard does your 302 rev?

bad luck dude.... should try 4.11'a bout 3600 at 100kays... but sheesh theyre savage!

XDman · 02-09-2004, 03:35

it only revs to 5000 grand but thats screaming aswell, as soon as i get out of school a 351 crank is going in plus all the other goodies, im getting the nine inch with 3.5's on wednesday arve, plus retung springs and added and extra leaf plus new bushes is gonna cost me 1745 bux... (9 inch all new bearings clutches etc) so hopefully she will go a fair bit harder

What manifold and carby are you running?

XDman · 02-09-2004, 03:54

standard manifold (2V i think) and a small holley... 465 i think but it has vac secs... im gonna chuck the 600 back on there and see how it goes (had jetting problems with it ill see if i can tune it nicel)

I think the 465 would work better. 600 is pretty big for a 5 Litre Engine.

yeh thats why we took the bigger one off in the first place, but still doesnt let a shitty v6 holden beat my falcon :(

Std as in 2brl or 4 barrel (are there 4 or 2 holes on the top) 465 is probably not enough half considering you have an upgraded cam. What are the cam specs? Put the 600 on what type is it DP vac squarebore/ spreadbore?
