turbo charge and super charge

Z32TT_maniac · #1 11-23-2004, 02:42 AM

they are not quite similar are they? and which one spool harder..one of my friend told me the super charge spool much harder..he said a V8 car with a super charge is just like a V12 car..wat the phuck!!!??? dats bullshiet

Super charger works on belt drivin power, it takes power to make power with a super charger, plus side to them are they are imediate power. Turbo Charger, uses exhaust gasses to turn the turbine to make power, takes NO power to make power with a turbo, down side is some of the larger older aplications have lag, and take time to reach full potential. As for the 300ZX you are quite safe with a twin turbo set up, it works great to moderately small turbos set up to make great boost at decent RPMs. Its all a mater of preferance really.

Niether will pull harder than the other, Turbos have a greater potential to make more power than a Supercharger but they cant make the power at the lower RPMs as there is not enough exhaust gas flow to spool them fast enough.

it's amazing what you can learn from reading...

if you have a 300zxTT, superchargers should be the last thing on your mind.

I am surprised he doesnt know the difference..... Mad Max used a supercharger........... loads o' fun on Big Blocks..... no good on little engines, less than 450Ci.

yeah...unless you have both.

i posted a link to a car that nissan produced in japan. it was a little hatchback that was 900cc's if memory serves me right. it was supercharged and turbocharged. pulled 0-60 times in a little over 7 seconds i believe. NOT BAD for a bike motor in a 2500lbs car.

just another reason why nissan rule's all!!!

EDIT: here we go i found it again. http://www.autospeed.com/cms/A_2216/article.html

this topic has been done to death. we have had a huge debate on this already. the only thing that came out of it was that it all depends on what you like, turbochargers and superchargers have their own highs and lows, and it all equals out in the end.

i want that super-turbo... i wonder if they're old enough to import yet

Hodo · #9 11-23-2004, 04:10 PM

I want turbine power....... Pratt& Whitney power..... JET POWER!!!! The ultimate turbo. :P

speaking of pratt & whitney, when i walked into work the other day, there was two brand spanking new pratt & whitney jet engines sitting on the floor. i would like to know what people pay for shipping for one of those.

If you're serious about more power from turbos and fear the lag, you could always use apply nitrous and have it shut down when the turbos do reach it's high potential.

DeleriousZ · #12 11-23-2004, 06:21 PM

good point neo.. once you hook that up it would be hard not to soil yourself every time you hit wot

Here we go again.
Hodo, sorry good buddy but both take take power to run, granted the turbo uses less, and low RPM's with turbo's has nothing to do with lack of power.
All of Pratt & Whitney piston engines had superchargers. There jet engines have axiel flow compressors.

K3 I'm ashamed of you. What do you think I run on my cars? JK, bud.

DeleriousZ I'm proud of you. Point'em in the right direction.

Freak your right, it's been beat to death and it appears a few haven't learned yet. As for those jet engines, little ones cost from $40,000 up, and the big mother's can cost in the millions.

OK school's open.
First of all a engine makes it's power with compression ratio. No compression no power, like burning gas on open ground, nothing but fire. The higher the compression ratio the more power the engine makes. The compression ratio is the multiplication factor of pressure on top of the piston, which makes power. I'm going to give 3 examples, only examples.

Engine #1 14.5:1 compression ratio
Engine #2 8:1 compression ratio with 12lbs boost
Engine #3 10:1 compression ratio with 7lbs boost

Which one of these engines well make the most power? And what's the difference in compression ratio of these engines?

http://www.goodvibesracing.com/Compression%20Ratio.htm

There is no difference except for the turbo engine, as follows.
Engines with low compression ratio's have very low bottom and mid range power, and no top end power. Thats where the turbo comes in.
Car mfg. engineers who build turbo cars find it easer to build production car engines that are turbo'ed easer to control with 8:1 pistons than with higher compression pistons. So the so called turbo lag is bull shit. The turbo just isn't making enough boost to raise the compression ratio enough to make power yet, but when it does make enough boost, bang, lots of power. That's why it's so easy to make so much power with our cars. The engineer's have detuned our car's so far, almost anything well improve it's performance.
Now a supercharger on the other hand is a positive displacement compressor and makes boost when ever the engine is running, so it's boosting the compression right off the start.
Now we can mask the so called turbo lag by installing smaller turbo's and lose top end, or inject nitrous in the low to mid range to over come the lack of compression ratio, or we can start with a higher compression ratio and a lower boost and have the same compression ratio the entire RPM range without the so called turbo lag.
With proper engine management (ECU) and good fuel it isnt a problem.
Because years ago fuel was the shits and so only engines with low compression pistons could handle turbo's (superchargers). Now with our technology it isn't true anymore.

awww....come on. what did i say now???

all i said was that if you TT and you dont plan on doing no ridiculous 1/4 mle times or anything. superchargers should be the last thing on your mind.

OK, you get all you atta boys back, I'm sorry

By the way. Did I explain it clear enough this time?
