nos for radix?

Has anyone put a nitrous kit on a radix supercharged 5.3? If so,how did you do it. Will i have to reprogram the comp again. I want more power!

You could use NOS,TNT or Nitrous Express for your truck.A mild shot (50-75) would probably work great.Any of the 3 companies above make kits for your truck.

I run the Nitrous express wet kit in my s-10 and love it. I think with a blower I wouldn't run more than a 50 shot, but what its gonna do is cool down that intake charge and probably net in more hp then 50. I don't know what kind of other mods you have but would probably open up the exaust with headers and what not befor nitrous. But I love the NX kit you can check mine out at my website

plus the purge looks really cool

OK,this is what i have so far.Radix supercharger,jet scu2000,dual exhaust with 21/2 flowmaster delta force race mufflers and no cats,O2 sims,e-fans and 4.10 gears with eaton e-locker.Radix comes with a programer and a heat exchanger.But i changed that out for a perma-cool six pass cooler with a 1250cfm fan.Headers and a stall are next,when i get the card paid off!

get some long tube headers for that thing and you will see alot of power. also how much boost are you running? I think about 12lbs should be enough. have you had it on the dyno if so what kind of numbers are you putting down??

Sorry,I've been busy cutting beans down here.Im running 6lbs and havent had time to find a place to do it in arkansas.But i g-tec it twice and got some bs numbers.One run i had 254hp & 377tq, next one was 689hp & 794tq ! Magnacharger wont sell smaller pulleys .

Make sure you monitor for any excessive detonation and keep an eye on the a/f ratio.

The superchips tuner that comes with the radix is fairly conservative and runs pretty rich. So you may get away with no tuning.

It's recommended that you back off timing a degree for every 50shot.

good luck and keep us updated,

btw, I'll be installing a 2.90" pulley on a '03 5.3L Radix reg cab Silvy, I'll keep you updated on how that goes, that may be an option instead of n20.

later,
