on here we go as of now we have a gen v, s2 inter-cooler, 1.9 roller rockers, 105 spring, cia, aeromotive stealth pump, zzp pcm, 42.5lb injectors, mps with a 3.4, 3.2, 3.0, 2.8 which im running currently with no problems loving it could other mods like machined lim etc. i have a nos wet system on the car now went from a 50 to 75 then to a 100 and i just purchased a nitorus controller bc the car starts to spin bc the nitrous is on a wot switch and at full boost all it does is spin for about 30ft or so then goes how much nitrous has anyone ran on the stock bottom end and had good results i figured with the controller i could go on up the the 125 or 150 and just progress it in so that it doesn't try to blow the tires off anyone have any details
 


slicks suck for everyday driving lol i have 275-40-17 nitto drag radials now at 20 psi still spins about 30 foot or so, im running a 2.8 right now lol all pulleys at once i guess ill swap all the pulleys out and run smaller all the way around, i dont wont to blow it up but ill have the nic cam in about 2 weeks so if it does well build her back up

Isn't it awsome when you ask a question, and all people do is pick apart your current mod list? Happens ALL the time. Makes em feel like a Boss... Feckin trolls!

Anywhoo... If I could offer any insite I would. I've not messed with Nitrous myself. So, best of luck!

isn it awesome when people who have no clue what they are talking about make a totally pointless post on your thread? makes "em" look like a douche...

rocket, believe it or not I am trying to help you here if you have a scan I could look at... without one it is gonna be hard to give you a good answer...
 
max boost with the 2.8 is 12psi with the ported lower manifold and the s2 ic, the air fuel off nitrous is 10.6 and the air fuel spraying it is at 11.2 scaning the air fuel with a dyno jet wideband, KR is at 1.5 untill you hit wot has the 1.5 kr during mild accesleration do to the motor torquing, the car does have headers, full 2.5 exhaust turbin mufflers so pretty much straight through, and the heads are all gasket matched what else would you like to know :) i see you sig. ill put up some cash to show you how slow she is oh with my dryer duct cia :)

my scan tool is a nemisys obd2 pretty much tells you anything you would like to know from transmission shifting, miss fire history, kr injector pulse widths you name it she can read it what part of the scan are you interested in the scan only logs while the car is running so kinda a buzz kill were putting it on hp tuners and dynoing it in the next couple weeks just tryin to figure the nitrous out before hand really would like to see how fare people have pushed them
