MusPuppis Posted June 28, 2006 Share Posted June 28, 2006 How does nitrous effect a boosted motor, as opposed to an N/A one? I've heard nitrous lowers compression and combustion temperatures, which would be beneficial in a turbo motor I thought, but, I beleive nothing I hear in casual conversation until its backed up by poeple I trust. The reason I ask, is we want flat 12's, high 11's out of the Festiva and nitrous is the easier way to do it. If we want more out of the motor itself we're looking at a new turbo, custom exhuast mani, new DP, larger injectors and other assorted tidbits. We were thinking a 50 shot on a WOT switch. The bottom end is good on the B6T to 300+hp, and we're looking at maybe (before nitrous) 200 at the crank. We would upgrade the injectors when doing this. We're already running a 255 pump, so we should be good there. Just curious, thanks. Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted June 28, 2006 Share Posted June 28, 2006 In my application with the supercharger we use 20% of NOS of a 175hp system which is aroung a 35hp shot as a intercooler effect. When we use NOS on a N/A engine at full potential it increases compression, thus the reason you have to retard the engine at 2 degress for every 50 shot of NOS. I think with a dry NOS system you can get away with a 100hp shot on fuel injection, the sensor will automatically increase the fuel for you. Hope this helps.

510six Posted June 28, 2006 Share Posted June 28, 2006 N20 on a boosted motor is almost like 2+2 =5.The 120rwh shot on my NA 3 liter turned into an over 200rwh shot on a boosted motor.The intercooling effect of the nitrous accounts for this.Make sure that you setup a nitrous sytem with the proper safeguards with at least a rpm window switch and a clutch switch in conjunction with your WOT switch. Run good fuel at least 110 oct. as your going to be packing denser fuel/air into your combustion chambers and a CDI ignition wouldn`t hurt either.BTW my car on the bone stock CT26 turbo ran 12.6@106mph with the 200rwh shot it ran 10.96@127mph. http://pg.photos.yahoo.com/ph/sss510six/album?.dir=15c7&.src=ph&store=&prodid=&.done=http%3a//pg.photos.yahoo.com/ph//my_photos Also it would help to know what EFI system your running as it would indicate if a wet or a dry system would be eaiser/safer to plumb.
