How much power do VR4's generally lose from the engine to the wheels?Originally Posted by bradc
all of a sudden i'm interested in modding a car, never realised such power could be gained from such little money, mmm 330hp!!

The best things in life have to be lubricated
Whilst fitting a new chip aswell as the other upgrades will give an increase in perofrmance/power, I have read about other manufacturers having chips with the ability to switch programmes,ie normal driving around town setting and sports/performance setting. Is it possible to get these type of chips for the VR4??
Mine had 154kw at the wheels when stock. It is difficult to guess just how much power I have at the engine, but considering it is an Auto 4wd car, I would say it would be around 205-210kw. I know that is more than what the car is originally rated at, but I think I'm about right
ciderisgr8, the apexi avc-r is a boost controller that supports changing between modes to differant boost curves. I know quite a few ECU's do as well, but most of the time you will need to upload a differant power curve to them, you can't just press a button.
what do I do to convert kw to hp? The web says Kw x 1.33 = hp. But that doesn't seem right.
That's the beauty of the Profec B - once set up, you have one single button for normal 'get out of my way' mode and press it for 'REALLY get out of my way mode' - even available with a remote.
Back to my un-answered question if I may:
Would a Unichip+Profec B at £200 more than a Profec B + s-AFC yield better results?

Unichip = Better than S-AFC
Unichip - So far as I know, its a proper remap of the cars ECU, including fuelling AND ignition.
S-AFC - Merely a piggyback which warps the airflow signal the ECU recieves, altering the fuel curve primarily but also the ignition curve as a result - you don't have control over that aspect of it. Good for mild fine tuning but nothing more.
Does have a pretty blue screen though

My complete exhaust was NZ$1500, which was from the downpipes through the whole car, with a muffler on each side. I think the downpipes were about NZ$400-500 by themselves.
