I have a 94 Cobra and am debating whether to put on nitrious or a supercharger does anyone have one or the other or had both. i need some info so I can make an imformed decission.

[weezer]

Supercharger > N20 everytime.

[TKOTLARZ]

i would definitely get a supercharger over nitrous if i had to pick between the two..im really thinkin about putting a turbo on my car...u can always put a supercharger on and then throw a 50shot on jus for a little extra..jus in case ur racing a close race..

How big of a shot can I run with the stock block

150 hp all day with the correct set up

Help me out with the set up I was thinking more along the line of 50 but if you know how to run a 150 share the knowledge

[AggieStang]

I would stay at a 125 shot at most with N20. 150 is pushing it but can be done safely. If I could make the choice again I would go supercharger. It's a pain to refill the nitrous over and over but it's cheaper in the short run.

your best bet as a newbie to the gas is get an adjustable kit start low and work your way up a you want a wet kit if you are going to spray 125-150. I use a MSD timing retard box to retard the timing when you hit it. You will want to retard the timing 1 dagree for every 50 hp of gas. I always say buy a new kit not a used one,thats just me personal preference.

Well there are a lot of options out there man... A supercharger (initially out of pocket) is going to be more than 3 times the cost of a good nitrous kit. true over time, the nitrous will cost just as much as the supercharger with bottle refills etc..

With a supercharger, the amount of boost you can run totally depends upon how your car is tuned (and who does it). You can run 12-14 psi with a really good tune, but a less adequate one might only be able to handle 6-8 psi. These stock blocks and internals can handle about 500 rwhp (that is generally the consensus since some have handled up to 550+ and others have cracked wide open at around 450). So it's all up to the tune. You won't get near that 500 mark with the stock heads tho... you can only push so much air through a tiny little hole, lol (unless your running some major boost, but that's just a bad idea). As far as superchargers go, I would look at the Vortech s-trim (that is probably the most popular blower for our cars) and any in the Paxton line up. The roots type superchargers aren't as effective on the pushrod motors as they are on the modulars, so only look at a Kenne Bell if that's what you have your heart set on.

You should also get your car tuned for nitrous, especially if you are running bigger than a 100 shot IMO. It is a good idea to tune it so that the timing retards (as ML Struck said) when you hit it. 150 shot is about as big as you want to go. I know a guy with a Fox body who sprays his 150 shot all day long pretty much off of every stop light, and he's had no problems. Nitrous is a quick and fun way to go if you are only looking to really get on it every once and awhile. If you are happy with how the car drives as it is (or even after some H/C/I work) and are just looking for that little extra juice when you pull up next to a camaro, then I would choose a nitrous system. I know a lot of people like the Nitrous Express systems and the NOS systems. I'm not that knowledgeable with the gas though, so someone can probably give you better info on that.

Or if you've got gobs of cash, do both

hope this helps!

Thanks alot for the info it will help alot and has me leaning towards the supercharger. Now I have heard s-trims are not a good supercharger to use, that I should lean towards a kenny belle. Can you shed some light on that for me

[WildWill]

The Kenne Bell and the s-trim are two totally different superchargers! The Vortech s-trim is a centrifugal supercharger and the KB is a roots type blower (it sits on top of the intake manifold).

The KB is an awesome blower and does good to provide a lot of low end torque, but it doesn't have the potential to make as much power as a centri blower.

I don't know who told you the s-trims aren't good superchargers, but I wouldn't recommend listening to them again! The s-trim is one of the most proven and reliable blowers on the market for our cars! They are priced very reasonably, they make great power, and they are very reliable. If you talk to anyone that has a Vortech, you won't hear anything bad about it.

The KB's are more expensive as well - that's sort of where I was going with the efficiency thing - If you spend $4000 on a KB sytem, you might get yourself to 300rwhp, but if you spend $3000 on a s-trim, you might get more like 330rwhp... (i'm totally just pulling those numbers out of my ass, so don't quote me on those). But like I said, if you've got your heart set on a KB, go for it! They are also very reliable and awesome blowers (not to mention the orgasmic sound they make when you get on it!!! lol)

[Venomous_Stang]

I am probably going to go with the Vortech it sounds like I get more for the money and I am all for saving a grand and getting a little more power. I would love the "orgasmic sound" but oh well. I could always do what the ricers do and get that fake blow-off valve lol
