I stopped reading after you mentioned something about Holden using a Toyota motor

i assume he thinks the alloytec is toyota for some reason....hes at least got it partly right that it isnt a holden engine...

Don't want to start a bloodbath, lol, but I think the Falcons have cleaned up everything there is to be won hence they are taking several things away from the Fords to even up the competition, if it was as you say, why would they disadvantage the Falcons ?

haha yeh i dont know but i did read about the all new holden v6 is a toyota motor, that they have just made it a bit bigger or something but i mite be just imagining it lol cant remember but there all s**t so it dont matter.

Any motor can be made powerful..... its just the fact that the ford motor is further ahead already and a nicer base motor to work.. but there are morons who spend s**t on v6's to make them go hard. spend half on a 4L for the same power and more torque but anyway...

apparently says my mates dad, fords in a five years or somethin myt be moving to v6s. i dont no myt be a load of crap.. but yeh myt be worth a mention

It is true.. the new falcon that just came out is the last to do so with an Australian straight 6 in it.. after that will come the duratec hi tech V6... remains to be seen how good a thing that is though.

i saw some data sheets on the ecotec stroker kit. it does claim 300+ but comes with a 8K price tag? if this is true then the i6 is lacking....

...lacking until the CMS 4.8 is finally released for the public

wouldn't the duratec be half the weight of the i6 as well?

half? i highly doubt

Look at sport compact drag racing in the US. Them buick motors have been spitting out well over 1000hp for years. Seriously what have we got? Nizpro builds 2 king motors. One to just sit there and look pretty and the other went into some guys car just cause he wants a sleeper xr6T (he will most probably never hit the stripwith it so we will never know what its capable of). I seriously want to know what that thing could have done on race gas and the wick wound right up. Lazy 1300+hp is my guess but for at least the next few years we will never know.

But as for the NA motors its not just extra capacity. Back in the old days it was but not these days. I was talking to a few race engineers a while back about this and they said that most engine builders don't understand the relationship between piston speeds, head flow rates and port velocities.

The correct way to design a big hp motor is to first have a target hp and operating rpm. Then workout ideal stroke, rod length, port flow. This way the piston speeds and port velocities work together to give optimum cylinder filling at the target rpm range.

And as for rod stroke/ratio's being ideal at 2:1. That's a crock in this day and age. Back in the days of soft iron blocks and chrome molly rings it gave the least wear, and with modern metallurgical advancements anywhere from 1.5 to 2.5 can be considered ideal depending on the port velocities and flow rates of the heads. Its the heads that ultimately decide how much potential the engine has, then the cam and finally the rotating assembly.

11.9 @ 138mph

I agree with this, the buick motor would need a lot of balancing before it was capable of the sort of revs needed for that power.

They are a bloody horrible thing in stock trim.

I shudder to think the amount of money that you would need to throw at it to make 300 nakw's...... especially when you consider you can have an LS1 for not that much more, which are lighter as well, making that power for about two cents these days!
