Turbo or Supercharger?

But if it has greater torque it takes less effort to turn it with greater results.... example, fine pitch vs coarse pitch bolts

I have no idea what you're talking about here......
I have to go load my trailer now so I can go wheeling tomorrow. Any of you guys want to E debate wheeling?:haha:

For the sake of this discussion the only thing that really matters is how much net HP you will have at given points on the RPM band. You can get to the same point with either a SC or turbo. The big difference is the SC will most likely have more parasitic loss so to make the same net HP the SC will have to make more boost. Now if the turbo car is at maximum boost the SC car could not possibly make the same net HP because over boosting won't make more HP.......
Clear as mud?

true, i totally agree...again, that a turbo, in the end, will make more hp and beat the supercharger, no doubt about it. but in a equally setup situation, ie, same whp. The supercharger i feel would have an advantage off the lineand still give the turbo a run for it's money at the top end, due to the low-end jump off the line. Whether what i said is complete BS I dunno, but that's is what i feel would happen... in some respect. It's like towing with a big block vs a 4 cyl. they can both do the job, but one will take more effort to do it and in the end one will have a disadvantage because of it.

Go load that boogy up:awesomework: But remember what helped you get that lump moving out of the driveway in the morning.

If their both the same HP there would be no advantage so long as both cars were truly equal. Set up the same, same weight, both were geared so you could keep the engine in the peak HP the whole race.etc.......I think I understand what you're trying to say. SC's tend to make power at lower RPM's than turbos. That just makes them different but not necessarily any advantage one way or the other. All that means is if your building a engine with a low RPM range a SC may be a better boost adder while a high RPM engine probably a turbo. But not always true...

hey turbo, ever heard of top fuel? if you want max response,=blower. max hp=turbo:beer:

Could you even possibly stick a turbo on one that would do a damn thing and not add too much complexity (take up too much space)? Is it even allowed? Every other form of drag racing, other then the "big boys" who are restricted to how much water the driver can drink before he/she goes down the track. Turbos are the only thing top competitors use. A small block turbo mustang running low 6's is much more impressive and shows how much better those setups really are.

Hit it on the head:awesomework: I guess I meant in my example that both cars had the same HP and everything (using the useless chart as the example) one could assume that the supercharger would have an advantage due to more torque off the line (according to the chart, and i know it's prolly not accurate but it's something to go off for now...)

Your car, 10psi blown, your car 10psi turbo, both tuned equally, turbo win's period. supercharger's are a thing of the past, turbocharging was black magic until about 5 year's ago, now it's the only way to roll period

Chop shop, it took 50 year's of top fuel racing with 800 inch blown motor's to get into the 4's. It has taken less than 5 to get a 4 cylinder turbo motor into the 6's. Imagine if a high dollar team spent some R&D time with an 800 inch turbo motor, it's only a matter of time. And no a turbo motor isn't gonna run 2's or 3's as they have reached the max (or close to) what the human body can do.

Shouldn't you be wheeling? I think I saw jeepmauler and some other buggy heading that way this morning. As I was heading to work...:booo:

Have fun guys.:awesomework:

its all at the line. a blower provides that winning response. they have more power than they need, its all about putting it where needed to win, not speed.:beer:

How fast do you think the top fuel cars would go if they didn't restrict what gear ratio they have to run,and what they can do to the clutch?And you must be unaware that they are restricted to a 500 cid motor not a 800:corn:

True dat
engine displacement 500 cubic inches
power 8000 horsepower at
8200 rpm
weight 2300lbs.
wheelbase 300 in.
engine block Brad Anderson Enterprises, forged aluminum
bore 4.187
stroke 4.500

8000 horses. Damn. Try building that with a turbo motor. The limiting factor on the speed is the traction.

**** it was just an example, I had no idea how big of a motor they used. I'm not seeing any brilliant input from you that benefit's the topic, get back in the closet:fawkdancesmiley:

If you are going to use a example,maybe you should atleast get your facts straight before you open your mouth and look like a ass:fawkdancesmiley: Either of a turbo or a supercharger can/will make power, I for one love the look of a supercharger on top of a v-8,In fact i just picked up a 8-71 for my 496 chevy I am building.the down side of a blower is that it takes horespower to turn it,but you still gain way more than it uses.A turbo uses wasted horsepower to make more horepower,but the downside is the added heat to the intake.As mentioned before there is the matter of lag you get with a turbo,not the case with a blower.

as mentioned before (by me), lag is becoming a thing of the past. And who gives a **** about heat when it's 1/4 mile? I'm just drunk typing, so don't worry too much about a response :redneck:
