How to choose ? NOS - Supercharger -turbo or stroker?

If I'm going to invested a lot of $$$ in one I want to make the best choice.

Stroker with a turbo and nitrous!

In all seriousness, it depends on what you want to do with the car. If you want an all motor car with just regular maintenance but more power, go stroker. If you want a car with big low end power, go supercharger. If you want all out power, go turbo. If you want power for drag or street racing but keep the car like it is now (completely streetable with no change in gas mileage) go nitrous.

Now obviously, this is all assuming that you are going with basic kits with little other mods to the car. Personally, I run nitrous. I like my car to be completely streetable with close to stock gas mileage, easy drivability, and when I want it to get nasty, open the bottle. Using that description, a turbo is the same deal, but turbos mean more underhood heat and they are always spinning, which means it's going to wear and that's more maintenance. The trade-off is power on demand, no bottle opening, and it's tunable for more power when you want it and less when you don't. It's also progressive power, whereas nitrous (not on a progressive controller) are just instant set power levels. Superchargers are power whether you want it or not, but it makes gobs of low end torque. It's more involved to upgrade them though (pullies and retuning) but the torque is incredible. Stroker motors always have torque (no boost lag) but bye-bye gas mileage and once again, the power is permanent, no going back to less power.

I would get a supercharger for the sake of saving gas, as compared to the big cubic inch engines. Turbos have lag and there not as responsive as a supercharger at low rpm's so if your looking for the 1/4 time get a supecharger. If you want huge top end a supercharger is still good when upgraded and so is a turbo. Twin turbo's however are nnnasty after a certain rpm. All and all when i weigh it out i still think id get a supercharger, its just superior power as soon as you touch the throttle.

ummmmm i really just gotta call false on that there info.... cause a supercharger can give way worse gas milage then a turbo, it all depends on what turbo, what supercharger and how much boost your trying to have that unit create plus a supercharger has more parasitic drag don't forgert. and as far as a SC being better for the 1/4 i don't really agree with that while a SC does give way better power in the lower RPM's that doesn't mean its going to be faster down the track cause i don't think your going to be shifting that low in the power ban to not see the turbos boost.

I would subjest to get a turbo just because it gives great power options and if you find yourself drinking to much gas all you have to do is turn the boost down and make sure you tune is good and you should be good to go, but that also depends on what turbo your looking at and where your engine starts building boost

I didnt say that superchargers have better gas milage then turbo, i was saying that they had better then a big Ci upgrade. And as for the 1/4 mile superchargers are generally faster, thats why all of the pro's use them. (ie. tope fuel, funny car, promod) well promod uses supercharger or nitrus, but no turbo's. Also i personally feel that a supercharger is more a symbol of american muscle then a turbo. All in all i would still want a supercharger over a turbo.

Sorry bro... just about of that is true...

Are you the one who was asking about what stage clutch you need in a recent thread? I never saw a resolution there...

If that was you, you'll want a higher stage clutch after any of this stuff... but you should do it all together at the same time.

What's your goal for HP? What kind of driveability are you willing to sacrifice? That will help the recommendations... asking, "super, turbo, CID, or nitrous - what should I do" is just way too generic to get any real sound advice tailored for your own desires.

accually alot of pros are using turbos to nowadays granted not on TOP fuel but there being seen more and more in the drag race world, while i completly agree with you on the symbolism thing for drivablty a turbo I FEEL is the best type of permanant poweradded because you can tune it to what you want and it never needs refilled. did you ever hear of Buddy Ingersoll(sp) who in the earlie 90's ran in the 6 seconds with a twin turbo buick 4.2 liter V6 and was then baned and was no longer alowed to race in the pro stock class... to fast for em'

With today's technology, turbo lag is virtually non-existant. Most street/strip turbo setups will yield near stock gas mileage with just daily driving. It takes a certain amount of throttle position to close the waste gate and a certain amount of exhaust gas velocity to even spin the turbine. Normal cruising down the highway is not even spinning the turbo. And with ceramic bearings, there is little to no turbo maitenance. Turbos have greater potential to make much more torque than a supercharger.

BTW, NHRA is going to allow turbos in Pro Stock in 2007. They are going to have to run a smaller displacement than the n/a cars. This will likely filter into the Pro Mod's as well. Fuel teams have researched the use of turbos but it's tricky since they leave the line at idle and then once they launch, their RPM barely changes the entire way down the track until the clutches are locked 1:1. This combined with proper exhaust scavenging would be very tricky on a 7,000 HP fuel motor.

Rootes and centrifugal superchargers can provide more of an "instant" throttle response than a turbo which makes them appealing to some for that reason. The boost curve is quite a bit different when comparing chargers to turbos. Superchargers create a parasitic drag on the crankshaft which normally results in a slight loss in gas mileage. Rootes and Screw type chargers are the worst on gas mileage.

A naturally aspirated motor can be built very easily to get good gas mileage. There are plenty of 400+ RWHP LS1's out there getting 25 MPG or more. It all depends on your cam, heads, intake, gearing, and tune.

Well considering prostock runs N/A carburated engines with restrictions i would hope that a turbo would win. And for Jay 02 as for profesional classes, they do infact run superchargers and nitrus i dont see how you think that thats not true, Tell me one professional driver who races a turbo, and i dont meen sport compact nhra i meen real professional classes. The only turbo cars i have seen ever are ones that race ultra quick 8, and other sub professional classes, and even then they are generally dominated by the blown cars.

[Dragkid1917]

Fasta... r u sure that there going to let turbos into Pro stock, not pro mod?.. theres a big difference between the two classes, prostock has been a n/a class for years, im pretty positive you meen pro mod, and yes in promod all motor cars are granted more cubic inches, and its worked out the cubic inches allowed for nitrus and for superchargers, for instance the superchargers are allowed a 400ci and the n/a 750 (something along those lines) But prostock is 500ci N/a and has been for along time, to introduce a turbo would create a whole nother class so i think that you meen promod. And yes big Ci engines can get ok gas milage if you dont push them i agree with that, personally when i start to race im going to run n/a because there very consistant.

I looked up what you said, and i didnt see anything that said that they were going to definitly do that, it is said that its a possibility in IHRA. I really dont think that will ever happen, otherwize superchargers would already be running in prostock, and then promod and prostock would be the same thing.

[fastTa]

Both IHRA and NHRA are considering it in the Pro Stock class. From what I hear, it is a very good possibility in IHRA, and that is interesting considering the mountain motor rules in IHRA Pro Stock. They are allowed to run up to a 840" motor depending on whether or not it is a Hemi or wedge motor.

[Dragkid1917]

Its a possibility for Ihra i dont really follow ihra at all however i follow nhra very closley as my father and I both race in the Nhra. As for prostock Nhra vs Ihra its different in that Ihra has less guidelines like the 840 ci engine, as to where Nhra is 500ci and everyone has the same restrictions. I really never think that they will ever put that in Nhra prostock, its a much more formal and honord division of racing then Ihra. Anyway i suppose you canyeild gobs of h/p from turbo or Super and you will probably never max them out anyway so whatever you want is fine, i just personally would rather have a supercharger. I like the sound and preformance benifits over a turbo.

I would go turbo for sure. Check out STS, they seem to have a good setup, its remote mounted and doesn't require an intercooler.
