Nitrous

Does anyone use it? What kind of issues if any? Whats the safe power level limit? ETC?

Timing needs to be reduced. With the stock intake manifold you can either go dry, after the MAF, or if you want to go wet you need to go direct port and run the foggers AFTER the variable intake geometry valve.

Also run 2 heat ranges colder plugs. 75 shot dry is safe, I wouldn't push much past a 125 shot direct port.

Do it right, get yourself a bottle heater, window switch, fuel pressure safety switch, WOT switch, etc..

If you are tuned don't do it because timing is advanced quite a good bit. I'm not aware of anybody that does a Nitrous specific flash, but call and ask the top ones (UM, C2, Uni..)

I was thinking about getting a progressive controller to. Maybe could run a lil more juice up top without the shock to the rods. I'm coming from a BT 35r 1.8/2.0 fully built B6A4. I currently have a 03 530i and like the torque so I wanna pick up a VR GTI instead of a 1.8T.

Turbo = fun whenever you want. Nitrous is fun when you have juice in the bottle.

Also keep in mind it takes a lot more money to make a VR6 quick than a 1.8T.

True. Maybe its VR/SC time then. I've done the turbo 1.8 thing, who knows. Right now the whole thing depends on finding the right car, dont care about what motor is in it, Ill just mod what I get. Just gotta find a clean bodied car

VR6 SC is really a waste of time/money. You actually suffer parasitic loss in the low end, and only get full boost at top end. Go low boost turbo instead. 300WHP from belt driven induction is way different than 300WHP from turbo. Just pulling these figures out of the air, but for example, with the SC you MAY have 30 more WHP than stock at 4k RPM, but 60+ more WHP at 4k RPM with the turbo.

Search supercharger sales in archived, look at how many people went SC, then ended up selling their $4.5k kit for 2.5K just to go turbo.

Prob just go back to 1.8T then
