Shop on ebay for a good wet nitrous system new or used.To beat the pontiac I would think you need a 250 horsepower dual stage nitrous system.Also see if you can find an engine programmer that lets you retard the timing while sitting in the car a must have for nitrous.The wet nitrous system will give you a fighting chance of not turning your motor into piston soup.I would set up for a 100 hp shot out of the hole with another 150 horse shot in second or third.This will also help save your motor because you won't be dumping it in all at once.The hundred horse shot will help you out of the hole without hopefully to much wheel spin.The higher the horsepower the shot of nitrous the more you risk damaging the engine.The reason I recomended the wet system is because most of the engine damage from nitrous is caused from running lean.You just might beat that pontiac.Have fun be safe and good luck.Andy J 150hp is nothing most good v6's put out over 200hp and as much as 250 v8's over 300 chryslers stock 5.7 hemi 345 to 360 hp.Also I said to use a wet system and while I didn't say it before I'll say it now don't push the button all the time only when you need it. Also something you might have forgotten andy is when you retard the timing you lose hp so with a hundred horse shot he might gain 75 hp.My answer is the most bang for the buck. Cold air intakes are a joke that provides little gain for the money. the other thing you stated about taking all of his 500.00 dollars might not be correct either as I said new or used.Also I stated to not use more than the 150hp shot if I had said 250 hp or a 500 hp shot then I would think you would be right to invalidate my answer.
