What Is Wrong With These Cars?

[tray_182005]

Yer they sell a 400 rwkw , With new leather tein suspension. Only sent a limited number over to go up againist M5 and that

[XRDOSE]

nizpro export them to the uk or somewhere...

tricked up abit to

and havent heard a thing about them since.....

[bradles024]

Been to Nizpro a few times over the last week or two, haven't seen any sign of any of these Typhoons?

[Bigkeels]

Videos been around for a while. Dunno what ending up happening with them.

I think it fell apart, there was never much said afterwards as to how it all went. they would have been an awesome car though with all the gear in it

Has anyone here driving a modified typhoon ever been beaten? My mate picked up his new car yesterday, VX Clubsport with 290rwkw, doesn't even come close to my 300rwkw typhoon

Guys guys guys - this has nothing to do with Ford or Holden, and everything with the average torque of a blown 4L 6, vs a naturally aspirated V8.

Remember, at 14psi boost, our lovely little 4L will actually be an 8L naturally aspirated's equivalent wrt torque.

Boy oh boy, I don't want to be anywhere near the steering wheel of my 370rwkw F6 Tornado if those V8 boys start adding turbos or a nice Whipple blower or something such. And that goes for both camp red and blue.

If they have a 6l V8, all they need to trample us would be around 8-10 psi boost, if we were running approximately 16 psi - which should get us close to my 370rwkw. By that time they will be sitting at a similar HP number, with a significant fatter torque curve, and the best part, distributed over a much wider RPM band - making for much more reliable engine than our little 6L shakers.

Hehe.

Have fun, and please don't flame me. My plaything in RSA was a very neat Ford Sierra with 357cid Nascar Winston Cup block, running 2x Turbonetics T60's, billet (internal balanced) rotating assembly, H-beam rods, JE Pistons, mechanical roller (turbogrind) cam et al. Was running 16psi boost for 750 flywheel HP, and it would have killed my poor UTE in all departments. Except fuel consumption of course :( Still wasn't bad for making use of a Victor Jr intake, modified to accept 16 injectors (staged for better atomisation), and a 4-barrel throttle body.

So, let's not go knocking the V8 boys, you're comparing apples to pears.

A golden rule-of-thumb: An equivalent output engine of a specific capacity, one turboe'ed, the other naturally aspirated - the average power output of the turbo'ed one will be much higher/fatter et al - whichever way we see it.

Have a good one - and remember, I'm the proud owner of a very quick F6 - who also realises it's inherent limitations.

I don't 100% agree with that, would say a 300rwkw turbo XR8 always be quicker then a 300rwkw XR6 Turbo then?

[MrBean]

Nope, what I'm saying is a 300kw turbo'ed car, say 4L 6 with turbo at roughly 10psi boost will be producing more AVERAGE torque than a naturally aspirated engine of 6L capacity, producing 300kw.

"Quicker" has nothing to do with it, as I've seen 250rwkw cars kill 330rwkw cars down the old paddock - if you talk about 1/4 time, as it's all in the launch. The 330rwkw car of course will have a higher ET (if the dyno was of course accurate)

[troytroy]

Concur with Mr Bean. Equivalent power is one thing, Torque in force fed cars will generally be higher than an equivalent powered N/A car. Another factor is where the torque occurs, How quickly the torque comes on and how effectively you can convert that torque to the ground. For high powered rear wheel drive cars that struggle for traction (thanks to under tyred Australian Sedans) a force fed car that has a very tight power band may be less effective than a more linear NA car that smoothly delivers power to the tyres. Conversely, if you can get the power to the ground - then Force fed cars will kill a NA car. Even a 290rwkw HSV will be dramatically different to another 290rwkw HSV depending on what cam (torquey or top end type) is being used, whether it's an auto and has a high stall converter (which reduces dyno output), if it's a manual whether it has 3.9 diff gears, does it have heads - which will effect its overall torque curve. And then there's the driver and the tyres. Power is not generally a very good comparative tool for how quick two heavy sedans can shuffle - especially when the power outputs start getting higher.

Mr Bean, you got any pics of that mighty sierra you had! sounds intense!
