NOS- bad idea? Other suggestions for performance? Your guess on horse power

I am putting in my rebuilt motor this weekend, I have my eye on a low end NOS boost from edelbrock with 50-75-100hp nozzles. If I only use this at the track or for 6 seconds here and there next to a Corvette on Michigan Ave., will it mess up my car?

What I have: 4bbl 600 edelbrock with electric choke, headers, x pipes that can bypass mufflers, flow masters, HEI ignition 50000 volt, performance cam and performance manifold, 3.55 posi, electric fuel pump with regulator, higher compression pistons, cylinder head machining and exhaust port matching. Do you recommend any other mods- I have 3 days before I start? What kind of HP do you think the motor without NOS will produce with the above mods.

 

I wouldn't be using NOS for awhile. RPMS should be above 3000 and it sounds like you have no NOS expierience. Not using NOS properly can create big noises.

 

What cam and what compression?

Need input.

 

i did a paper in college on the user of NOS in car engines..

90% of all cars on the road today can handle up to 75HP shot of NOS with ZERO issues.

any engine that has been re-built with a decent cam, piston, and intake can handle up to 100 HP shot.

and then of course the more you put into your engine the more you can handle..

a hyperuetectic piston can handle 125HP without issue, just make sure your heads are good to go, and a brand new head gasket is in place.

 

it doesnt matter what kinda engine you have built if you spray it and a low RPM or if you have not enough fuel it will blow

 

Just follow the manufacturers instructions to a "t" and you should be ok. Ya gotta start somewhere.

 

W/ forged pistons,a GOOD fuel system and conservative timing you can spray 175 easily and safely.ARP rod bolts and head studs (vs head bolts) are good,cheap insurance.NEVER spray it under 2500 rpm.As a rule,for each 50hp you add,you retard timing 2 degrees.Might want to run a heat range or two colder plug when you plan on juicin' it.The directions in most nitrous kits will tell you all you need to know.302s are notorious for blown head gaskets under boost,that's why I recommend the head stud kit.Happy spraying!

 

You do need to properly break in the engine BEFORE hitting it with power.

 

The Edelbrock performer set up you are looking at gives incredibly rich (read safe) jet combinations. I played with it on the dyno and was able to lean it out quite a bit and still maintain safe A/F ratios. If you stick with their recommendations, I wouldn't be worried at all.
