and who decides if its legal?

theres an EB on here with std head and no boost that did a 13.7.....

so no it dont take a much to beat that time....

then theres all the 302 falcons which can very easily pull these times plus a lot more

as has been said a million times before its the short first gear that makes commodores seem so responsive.....60kph vs 80 in the ford...also they tend to carry a little less weight (flimsy s**t actually - thats why they cant hack it as taxis)....end of the day it aint the V6 that makes them quicker...

factory supercahrged v6s had 171kw....vct au motors had 172kw...dont give me this crap about the v6 being detuned....so was the vct (by quite a lot)


I said more legal then a majority of eseries/AU that run that quick.
There are a handful of N/A E-Series/AU running 13's... and you really have to nail the run to get it.
So don't give me this s**t of 'doesn't take much'
If it didnt take much then there would be a *s**t* load more running 13's..
as for 302's running quicker times... theres plenty of 304/308's running quicker times too, so your comparison it pointless.

fact is, there are Factory Supercharged Commodores running 11's/12's, It'll cost you a bit of coin to get a Legal Falcon running those times.

I'd be interested to see the difference in the power curve from the V6 with and without the S/C.

Have to disagree with the v6 being the more reliable motor, over the years i've been in plenty of friends/family commo v6's, infact theres one in my driveway right now that has literally just had over 1500 worth of parts spent on it to try and diagnose a problem.. still isn't working and as soon as one problem is fixed another pops its head up. This is not a high km thrash car, its a low km example driven by a woman in her 60's.

Not to mention my friends v6 VS which has broken down many times and his younger brothers VR which is no better.

Give me a 4l anyday, my EF has yet to brake down for me or the PO and still outruns many modded v6's with just intake, extractors and exhaust. Once the diff gears and cam are done i think it may even give my 5.0 merc a run for its money (till the new engine :twisted: ).

Not to mention when i had my lane's which were left sitting in the driveway for long period's of time without starting only needing a battery and very minor maintenance to get going again (one was left sitting untouched for 2 years as a parts car..)

Whippled running 11's in Perth.

The stock M90s were basically there for towing etc..Until Holden decided they could make a sport package out of it (Xu6 what ever..)
But throw a whipple on a basically stock buick, and its a completely different story!

The M90 is only just big enough for the 3.8,it's built this way so when souped up it won't brake stuff.This is very simplistic as there's other crap involved as well.
The M90 won't push enough air to go big so to speak,21PSI at around 210 RWKW doesn't make sense,unless the pulley is rated at that for another charger the M90 won't push 21PSI it can't spin fast enough. Raptor Superchargers(yes he does Holdens) are making around 220+RWKW on the VS/T V6 Holden at around 10PSI so obviously the M90 can't do the numbers as it's too small.

probably also depends on where that 21psi is being made.
21psi @ 5000rpm? doubtful.
the M90 prob drops off boost the higher the RPM's go as it can't keep up anymore.
unlike the raptor which needs RPM.

Agreed on some of it.
I don't think the M90 will push 21 on a 3.8 at any speed or pulley myself it's not a big enough unit.
I've got about 3lbs boost by 2600 revs and more outright RWKW at those revs than the N/A BA six with extractors and stuff,with a sick torque output to boot so i don't need to rev it that hard to get going..

EFFalcon...therre is no point arguing with u...

if your impressed by factory supercharged ecotecs then good for u....

this forum is for people interested in modding falcons, particularly the 4.0l six....

i dont see why u think the the ecotec is a better motor....perhaps your in the wrong place

heres the facts...

the best NA ecotec had 152kw..best boosted one had 180kw

best NA 4.0 had 172kw (AU) 182 (BA)...worst boosted 4.0 had 240kw(BA)

no comparison really...but then i am a one-eyed ford supporter

You forgot the xf and ea turbos, not sure on the outputs but. And super rare.

funnily enough i have multiple highly modified falcon's... so its pretty clear where my vote goes.
maybe i have more right to be here then you?

however you can't deny the potential of a supercharged 6.
I never said the ecotec was a better motor, and i don't think it is. however they're not as much of a dud as everyone makes them out to be.

might be worth looking at the Buick Grand National for some factory figures, for a 1987 model car, 206kw from a turbo 3.8 buick and plenty of torque.
and now you're comparing the ecotec to the Barra I6? Why don't you compare it to an engine of the same era? AlloyTec's have a 190kw version?
as for semi-factory 'performance' boosted SOHC cars... the AIT Kitted EA's were nothing special.. the stage 1 'kit' was 195kw.

stage 2 was a more respectable 245 but.. we're not exactly talking 'factory' cars here.
