Simulated VN VP VR, V6's

Sounds like fun stuff to do. Good work.

No these are good VR results, not the 9.3 secs claimed by wheels magazine.

Ah yeah no chance a VR will do 9.3 to 100 I doubt even a V6 Calais would be that slow, but remember 60 mph takes about .3 less than to 100 km/h. In fact I've driven a VR V6 Calais with my foot on the floor and it was pretty quick !

My VN Lexcen (50?kgs heavier than an executive) runs 7.15 0-60mph all day with the stock chip and a CAI on it and can just crack it for a 6 with more spark advance. Macks VN executive used to do 7.3 stock but it's in Queensland with not so favourable weather conditions like I have down here in the deep south so I'd be up a fair bit on power just because of location. But both those cars seem to be close to their best possible time. A VS executive should be _slightly_ faster than all of the above cars or at least equal to them

You did a good favour for VR owners, I dont care if we are the slowest or fastest, but 9.3 secs, just crap. Thanks

Slickholden, I don't like to be the bringer of bad news but there's a very good chance your car would be no faster than stock (or even slower) once it has warmed up with the pod on it, just +15c worth of hot air could cost you 7nm of torque right through the rev range and that's most likely more than you gained back with the exhaust. Throw the pod to the tip :thumbsup: and get the coldest air into the thing you can and then go to repco or somewhere and get a cooler thermostat, around 175F or even a bit less than that AND make sure your throttle body does open 100% straight, those are things you can do that WILL make you car go faster and they are cheap.

:driving:

Worth a mention that all those calculated times are with a perfect air fuel ratio, something alot of stock VN's don't have anymore or never did have. That's why the perfect spark advance times aren't much different, because you gain most of your extra memcal power with the fuel ratio getting fixed, if that's allready ok you don't see much gain on the V6's (esp on the VN which is almost maxed out from the factory (but also most likely to have a crap air fuel ratio))

I stuck back the Air box today, Slower take off i can feel that, But mid range power is wheel spinning. But the best thing was it's been a touch ruffer with the pod and as soon as the old Air box went on the idle everything went better.
I did a sneaky i added a tiny bit of hose where the gap is in the front of the Air Box to between the light and radiator to hopefully trap some colder air up it. I could feel the sucking at my hand very easy.
