Complaining About Boss V8 Design And Performance

There has been alot of people around Australia complaining about the lack of performance from the boss Motors and that the 5.4 Capacity is to small and the stroke to long. Subaru can make 206kw from 2 litres and the XR6t has been seen to make 300kw with 8psi boost. I think ford should really look at the supercharger as the way to make easy power.Use the 290 boss as the xr8 engine, supercharge the 290 boss for all GT's, and supercharge and intercool the GT HO. But as a smart tactic still rate the XR8 at 260 kw and the GT at 290 and GTHO could be 350kw . Nissan has been doing this for years with the skyline GTR rating it at 206 kw but when you dyno one it makes like 190@ the 4 wheels which is like 270kw but nissan never claim any more they just let the performance times do the talking . Ford dont need big numbers just have the road speed to back it up. Mercedes AMG Coupe weighs in at 1800kg but its supercharged v8 propels it to 12 sec 1/4, it will be cheaper for ford it supercharge and engine than it would be to loose 150kgs

All jap cars are rated at a maximum of 206Kw as there is a gentlemens agreement amongst jap manufacturers not too exceed this figure - but they do - anyway.

Re: Complaining About Boss V8 Design And Performance

I think weight reduction still should be an important factor. Remember that it also works to the effect of improving handling performance, which is a thing that people tend to forget about.

but yeah, a bit more power definately would help too.

Lets hope BA2 has less weight and a bit more power.

Re: Complaining About Boss V8 Design And Performance

i think a part of the problem here is ford and holden not wanting excessive adverse publicity. the last thing any of us want is a repeat of the supercar scare of the 70's. there has been a lot of publicity in WA over the last few weeks about kids driving into things (poles, trucks) in 'high power cars'. we have already seen the muscles flexed with the way these cars can be advertised, we really can do without some dickhead journo / pollie (and lets face it, MOST of them are dickheads) trying to get some cheap story / vote by pretending to care about road safety and offering up what is a highly visible solution.

we all know it is would be a knee-jerk reaction with little or no impact, but it satisfies the ignorant masses short-term lust for quick fix soltions.

it seems that 300kw is the upper limit. you never know, we may get a situation like japan where all of our cars are quoted as having 296kw, regardless of the real figure.

Re: Complaining About Boss V8 Design And Performance

I beg to differ about the weight. Most BMW and MERCEDES and JAGUARS are very heavy cars and yet they handle very very well. An article in the Dec Wheels says that if ford was to start using aluminium panels and body structures that the XT falcon would cost $50000 i dont think this is aceptable. if we cut corners we will end up with body control like the commodore all flimsy and creaking doors and dash rattles. The BA is a good solid car that handles well but could do with some shock tuning and more power in V8 form, lets not wreck a good chasis and car by trying to save a few kgs

Re: Complaining About Boss V8 Design And Performance

In the US we have what is known as 'CAFE.' Corporate Average Fuel Economy. Exceed the set 'average' and the manufacturer faces stiff fines.

The imports from Japan and Korea are smaller and they do not have the larger and heavier sedans that the domestic manufacturers have.

A 'Luxury Tax' is also levied against autos that have worse fuel mileage than the set standard regardless of CAFE.

Part of the result is that cars are 'detuned' to achieve a mileage goal.

Of course this doesn't stop the buyer from improving performance...

Does Australia have a similar intrusion by government?

Nope !

Remember that Australia is the land of the "stick your 'International Greenhouse Emissions Policy' where it fits" strategy Kinda irresponsible, but funny and good for the cars

EATurbo, I like the idea of the understated power. I would hope that they differentiate an HO with more mechanically than a intercooler - maybe blueprint it as well or something.

Re: Complaining About Boss V8 Design And Performance

I was doing some reading on the Ford 427 and it's 7.0 litre V10. Basically they took the 4.6 Cobra engine, increased the bore by 4.6mm to 95mm, the stroke by 7.6mm to 98mm and then added two cylinders. My question is why can't they increase the bore say to 95mm and reduce the stroke by about 10mm to 95.8mm? Wouldn't that allow the boss (and the 220 engine in particular) an easier time achieving higher revs and hence more power?

This is an area that has been of great interest to me lately, and I have been thinking about putting together a little article on this very topic; basically an analysis of the various performance sedans from all over the world. I think it should be an interesting read - it will definitely raise a few questions, and probably answer a few more!

Will keep y'all posted
