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'd beworried about that bake-a-lite intake manifold! One nitrous backfire and BLAMO!

I was wondering about that too, but didn't know if maybe he meant like 300WHP on the stock internals or soemthing. a 300 shot would almost be certain doom for that motor.

yes to clear that up the engine itself should be good for 300- 350 H.P not a 300 shot of nitrous, I like fun but not that much. :funny: so what alum intake then. n/ex site says it should be o.k on the stock engine?????

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.

Odd way of thinking about it, but you'd rather have your intake manifold blow up than for it to keep that pressure inside and blow out the motor.

If you're concerned, you can add burst plates to the manifold that you can easily replace in the event of a nitrous backfire.

Spraying water/meth with nitrous will also help keep it safer.

so what is AFR ???? I was talking with my son in law he has been running nitrous in his TA for about 3 years now , and he says no probs. I think I only want to go 75 shot should be enough with the mods allready done, and am not really looking to do any serious racing just have some fun. :huh:

AFR= Air/Fuel Ratio

As mentioned above AFR = Air Fuel Ratio.

Your son drives a TA... not a 4.7L... I was not saying Nitrous was or is a bad thing.... I think Nitrous is a great thing... I love it! But your 4.7L does NOT!

I was just trying to arm you with some incite so when you do it you know what your up against. Your sons TA does not have the same pistons that your 4.7L has... So on his TA its an entire different engine and it will tolerate N20 better then your 4.7L will... and on a TA I would tell you the same thing... No problem.

If your going to run N20 just make sure your AFR are close to 11:1 ball park ... if not you could be picking up a pile of engine parts after a couple of runs.

so yup I agree the T/A has a completly different motor , so what is the best and cheapest way to monitor the AFR. I also talked to the guys at NX and they are saying up to a 75 shot should be no probs. to set the record straight the thread I was reading says the internals should be good for about 300-350 H.P there is no way I would even think about a 300 shot. So about the AFR again monitoring and such , don't want a blown engine :waiting:

We use the DYNO JET Wide Band Commander Data Logger on our 2002 4.7L engine. I have never had any issues with it and it allows for easy play back with the use of the supplied USB cord. I plugged on end into the data logger and buried that into my dash... I then ran the USB cord into my ash tray from the back... so when not in use I can tuck it into the ash tray and close it... out of site out of mind. When I want to data log I just pull out the cord and plug it into my lap top.

After I record I save the file and then reply the file looking for any issues with the AFR... You dont need to do this all the time... but when setting up getting it tuned you will find this as your best tool in the tool box. You may want to data log at the track as the information provided would allow you to make the needed jet changes if you started to run lean or over rich for what ever reason.

If you have any questions please feel free to contact me.
