Turbo or SC!! - Honda Prelude Forum

mike02 · 02-26-2002, 06:29 AM

I currently dont own a preluded, but im looking to get one. My friend has a 2000 Lude and I love it! He only has an AEM CAI. Well now im looking to get one this year sometime and my question is...... which is better a Turbo or Jackson Racing Supercharger? Also what are the gains of both?

LuDeS · 02-26-2002, 07:10 AM

really depends what you are looking for.. Both can be reliable.. Max power is turbo.. Linear power is SC.. thats just some of the differences do a search and im sure you will find alot of topics on this debate.

There is also plenty of information on this in the Forced Induction Forum.

if u are going to get a Type SH, i suggest that u get jrsc because i heard numerous stories of how the turbo and atts dont mix well...which means problems...

either forms of FI can/may give atts a problem... the problem lies in the fact that atts wasnt programmed to handle that much additional power/torque and the reason more people with turbos complain is because turbos generally produce more power...

JR's prelude puts 235 to the wheels. I dont believe anyone here is quite at that peak yet, but close.

As far as turbo #s, depends on too many factors to say. And like suggested, check out FI. Good luck.

Ive seen SC at 235 also....with room for improvement....you could get 245 tops at 6psi....turbo ive seen almost 300 whp on a "stock" setup.......up to you and what you want

It depends on if you get a ball bearing turbo or not. Ball bearing turbos have very small lag, so you relatively get the boost right away. I don't know where all these people did their research, but the turbo could be more reliable, but it costs more than a simple stock 8 psi JRSC. You'll run 8 9 psi on the stock internals on the turbo you'll get without problems. The thing about supercharger is that you're putting constant pressure on the cylinders and the block, because it's belt driven to give you that immediate power/torque. Turbo, you could cruise, while putting small amount of pressure (little more than stock) on the engine. Turbo only puts pressure on the engine, when it boosts. It all depends on how you set it up. You could have a bigger intercooler to cool the engine better, or better a engine management. F max turbo puts 288hp on the wheels, (stock is 144hp to the wheels on 5th gen prelude.) Turbo is more efficient, because it recycles the combusted engine gas, while superchargers don't. Only thing about the turbo is that you have to replace oil, and also have to cool the turbo down before you shut off the engine, but that's taken care of now by some smart electronic controllers(it runs the engine, after you shut it off, to cool the turbo. ) i'm getting f max turbo, so i could eventually build my engine up and run 18 psi on it, or more.(about rated 400 to 500+horse.) i just have to save up hella money, but I'm half way there.

i hope this helped. Oh, and do some turbo research or talk to a mech, who works on his/her turbo car. I learn most of it through talking to mechs. peace out.

Both SC and a turbo put constant pressure on an engine. Look at the boost gauge of a SC Prelude, you'll see that its under vacuum the same as a turbo prelude. Dont forget that a turbos output is also related to what the engine is doing because its powered by exhaust gases instead of a belt. A turbo runs hotter than a supercharged Prelude and is harder to keep cool, while the SC puts slightly more pressure on your cams, not that you have to worry about that at all though.

Just wanted to straighten that out. Supercharged is usually more reliable becuase people with a turbo either run higher boost, or dont spend the amount of money needed to make it reliable (cooling measures, tuning, blowoffs). But they'll be about the same reliability if each is done correctly.

Just wanted to add that in my above post I mean it's under vacuum when cruising, and then boost when accelerating. I wanted to save the time of someone correcting that poor sentence.

supercharge!

Turbocharge!

screamer5300 · 03-03-2002, 12:00 AM

simple answer. My turbocharged prelude could beat up your supercharged prelude.

nuff, said.

screamer5300 · 03-03-2002, 12:05 AM

Ludacris, I think maybe you should rethink what you said. When in full throttle, there are pressure on the engine for turbos, but they have to build up the boost in order for it to explode at certain rpm, so you don't really put that much pressure on the engine when you're cruising in your turbo lude. SC puts pressure on the engine from the 0 rpm. I think turbo is more reliable, if your not over crazy. Besides, people who don't do research about what they're getting into should deserve to be punished by having their engine blow up in their face.

i_krayzie_i · 03-03-2002, 12:55 AM

i would think supercharger would be better if your a daily driver b/c i read on the jrsc website that when your not stomping on the gas it bypasses the blower and just does the regular operation saving gas and engine life. plus turbo is a big hassle

01_H22A · 03-03-2002, 01:50 AM

he never said anything about daily driving =)

mike02- research as much as you can before you get the turbo or sC

i mean, if you have the money, get the turbo... just because the blow off valve, and intercooler is badass.

soon2bsh · 03-03-2002, 05:42 PM

yea that blow-off sound is bad ass.... but the whining is even better! heh

turbocharged

....either way, expect to spend some $$$$

I repeat - a turbocharger turbine is always working, it is pushed by exhaust gases. A supercharger is always working, it is turned by the accessories belt. A supercharger is not putting out boost when you're cruising around, check out anyone's car who has one. The car is under vaccum. Like a supercharger it depends on the RPM, they have to build up boost as well.

Lets clarify that either one of these is basically the same thing, just different ways to go about them, but they're both air pumps/compressers/turbines. The JRSC kit is a roots style Eaton supercharger, so it looks quite different and is operated by a twin corkscrew design, as opposed to a centrifugal supercharger which looks very similiar to a turbo.

Both put extra stress on the engine, and both a great options. Just choose which one is right for you.

Supercharger - less power/less money
Turbocharger - more power/more money

Actually, the roots type isn't really a compressor...
