'charge.

for one, you dont have a cumulative upkeep of topping off a bottle. secondly, you dont HAVE to run a second fuel system or monitoring system. third, it's always there...even after 40 or so runs down the track, where your bottle would have run out after the fifth.

it's easy to tune, and you dont have to make 2 tunes, one for NA and one for NOS...all you might have to do is run a brake booster vacuum or switch over to hydro-boost for brakes.

edit: plus, it's not nearly as harsh on the engine....imagine, rolling down the street, then bam....an extra 100 or so hp gain over about 1/8 second...imagine what's happening to the bearings and wrist pins...pressure and undue stress.

 

I have a Mallory 685 box that will retard ignition timing when the nitrous hits. Therefore, there is no need for two seperate tunes. As for the nitrous being harsh on the engine, I think a properly setup system with a modest shot will pose little threat to the motor. People run into trouble when they cut corners in the setup or they get too greedy with the jetting. The same can go for a turbo/supercharger setup, get greedy with the boost, and you can easily trash the motor if it isn't setup too handle it.

 

Go with the supercharger, the power will always be there, wont have to worry about getting bottle filled all the time.

 

My bet is that next to none of the ppl voting for a supercharger would be able to outrun a forged 383 on a 400 shot

 

I think I would rather have nitrous then a super/turbo, mostly because you can hide them better, gas milage does not change (even though many FI cars seem to gain mpg), nitrous is not a constant stress on parts just when you hit it. However since I dont have nitrous or a forced induction car, my opinion is basicly well an opinion lol.

 

most can't outrun a good stroker on a 150-200 shot.

Street car/roll racer....FI
weekend warrior/drag racer...Nitrous
Hardcore Record setting Drag car....TURBO

 

Well put.
For a street/strip car you just can't beat the bottle.

 

blah @ cheater spray...between the two (especially if money isnt an option), supercharger is the way to go, especially for a street car. Why would i say that? Its very simple with a supercharger...Its permanent power, you cant run out of it like a bottle. There will be no excuses! enough said about choosing between the twe.
Nitrous is something id use at a drag strip, personally i take pleasure in beating street cars (especially ricers) equipped with N02, in the future i plan on going procharged or turbo'd. just depends on how things end up looking.

 

Mostly Streetcar = Supercharger
1/4 only, or "Midnight racer" = Nitrous

I run and vote N2O on my street/strip LT1. Although on my future stroker build I have not decided between nitrous or a rear mount turbo. But I guess thats a whole new topic. What type of turbo was everyone referring to?

 

that to me is one of the things I like about Nitrous...you CAN turn it off

nitrous cars are also not as affected by weather changes as FI cars...as soon as the bottle opens there is always good weather

 

Exactly!
Sure it's fun to drive around with 550hp all the time, but do you really need it all the time? 400hp is enough to have fun driving around and whoop on just about every car next to you at the light, and if it's not open the bottle.

 

why is this a debate? if you think about it, they both make our lt1s look awesome, sound great, and make our cars fly. I'll take an order or nitrous witha side order of forced induction. END OF DISCUSSION

 

well, with the super/turbo setup, there's always downward pressure on the pistons. so, when they reach TDC the slop found in the machining process that usually allows pistons to continue traveling upward after the full length of the rod reaches max is no longer in play. this is why much older cars with turbos are in much better condition than a NA car. there's no slop on the wrist pin, and no wear on the pin or on the piston. the constant force keeps all the bearings tight.

and for those who say you can't turn off a charger......how about a 1lb blow off valve??? sure you'll always be hissing, but it's possible. and i've seen some superchargers that look like intake manifolds. well, you could use a vortec supercharger, or a SBC whipple and mahcine the mounting plate to fit the ltx heads. i've thought about that. or you could go with a STS turbo and come up with some kind of valence. but you'll still hear it.

 

if u have the money... turbo + nitrous
