I have recently gotten a new forged 408 which should be in my car in another week or so. I bought the motor and was told it was fully built to handle a huge nitrous shot. Forged internals/nitrous gapped rings/head studs/main studs etc etc etc......anyways i need alot of info from some of the guys on here that are really laying into it. I want to shoot 300-350 on the motor. I have decided to go with a direct port setup. But i was wonder how many stages colder should i go on the plugs? Also should i look at a dual shot or just some type of progessive controller.... Or both??? Please share with me what kind of setup all you guys ahooting these larger shots are going with. What do you like/dislike when it comes to large shots

Thanks

o would prob dual stage.. like a 100 kit out the gate then 200 a few feet out.. keep stepping up the initial hit as you want to leave on as much as you can..

as for plugs i ran tr7ix's with no problems on a 300 hit.. but i was conservative with timing and had 112 in the standalone..

sounds like your gunna have one hell of a ride.. nake sure your tune is dead nuts and that you have enought fuel.. then go ***** to the wall..

 

Direct port w/progressive controller is what Im doing on mine.

 

2 stages, 200 off the trans brake and 150 a few feet out.

 

I have three stages. 200 off the line 100 shot at 4600 rpm's and 50-75 dry shot at second gear.
