Thinking about adding nitrous to the 4.7 , anything that I should be wary of. Upgrades , trans , cooling , etc. or will stock be o.k. planning on 100 shot. truck has 120.000 klms , runs great just changed the plugs no issues. Air raid C/A intake , new exhaust 2 1/2 inch , SCT, ramair says should be o.k for 300 h.p in one thread I was reading , what do you guys think????? Thanks in advance :waiting: :waiting: :drive:
I hope you didnt mean "AIR RAM"... because I think your playing with danger with 75-100 shot.
The 4.7L piston tops are less then 1/8 of an inch from the top ring... Thats SUPER THIN. This is fine for NA applications but its flirting with disaster when adding Nitrous.
A small amount of N20 with the proper metered amount of fuel is fine... I think a 50-75 shot will be great... as long as the AFR is good. You need to keep in mind that your 4.7L will NOT have a tolerance for any LEAN conditions. Go lean once at WOT for and your top ring will get super hot super quick, expand and seize itself to the side of the cylinder... your pistons will rip the tops right off and then begin to pulverizes itself from the inside out.
If you want to run more then that you will need to invest into an AFR WIDE BAND DATA LOGGER like the WIDE BAND COMMANDER.
This divice will allow you to monitor your AFR & RPMS when at WOT... You can record your runs and immediately go back and view them to see whats going on... this allows you to add more fuel to keep things on the safe side.
If you properly use a Wide Band Data Logger I can see 100-120 shot being safe... BUT one hickup or one OOOPPPS got to lean will give you a bucket of parts in no time.
My advice is to not exceed a 75 shot without a Data logger and not to exceed 100 shot with a data logger on the 4.7L engine.
If you want to build a 4.7L that can handle a 300 progressive shot... give us a call we can certainly set you up with the right forged parts to get the job done... We also carry Nitrous kits.
SPEED SAFE, AIR RAM
