I was just wondering if you want to boost only 5 psi, do you need to use a intercooler?

 

You should ask the forced induction forum this question. Why would you not use an intercooler. If you have a budget that doesnt allow you to use one then you shouldnt be boosting your S2000.

 

You don't really need an intercooler to run forced induction, but it does help a lot in cooling the air temperature before it being ingested by your engine.

Many people run the Comptech supercharger without an aftercooler.

 

Those do run a little cooler.

I would rather just buy an intercooler on ebay for 200 dollars.

 

having an intercooler is more beneficial towards performance. colder air is better that hotter air

 

They are called aftercoolers, but you can buy the Comptech supercharger without it.

 

Superchargers are very different from turbos in this sense. Superchargers don't emit nearly as much hot air as a turbo.

 

I know that, I was using it as an example.

But to tickle your boat, Greddy sell some of their turbo kits (for civics and integras) without intercoolers.

 

how so? you get heat as a form of energy when you compress air(yes you are not dealing with spent gas in sc but you will still get heat when you compress air), most root type SC have major hard time packaging a heat exchanger because of the location of the mechanism(air to air will almost not worth the plumping loss at low psi application, that's why most of the root SC with heat exchanger are water to air)

to the op: yes you can, but you also can run a window 95 on a vista 64bit hardward, the bigger question is why.

you already know colder air is more condense=less pre ignition "opps"(sometime to think about beside cutting cost and running less part)
beside packing more punch, you also get a wider safety margin.

you can get aways with it with low psi set up but you are about 80 percent done, saving on the 20% sometime doesn't make sense if you paying for a sc/turbo, etc

but that;s just me

 

Intercoolers are cheap.. wtf.

 

most people can't deal with taking off bumper, trimming stuff off, mounting and fab'ing and welding at the same time(aka candy **** tuner)

 

nice lol

 

IM really lazy and Im sure I could figure a way to put one on with out taking the bumper off.

 

topmount, you're good to go

 

5 psi without and intercooler is just fine. at 5 psi your not compressing the air very much and intake thems should stay relativaly managable. BUT its always best to run one. you can get a small cheap ebay one and will more than get the job done with what your looking to do

as for SC and turbo being different temps compressed air is compressed air and the temps would be minimally different. thats why roots style SC suck because they create to much heat and hard to cool it so power production falls off after boosting for a gear or two. a centrifugal sc is basically a belt driven turbo and much easier to route to an intercooler so the power gains are better to a certain point. everything has its ups and downs but thats all preference
