I was wondering everyones take, on the camdensupercharger. It is a mod that has been interesting me for quite sometime.

Also if supercharged, would a n/a engine be best. Our would a turbo engine(for lower compression) be better?

I know a turbo would make more power, but i would like to make my engine as unique as possible.

please feel free to leave any opinions you have

thanks

Actually, I think supercharging an NA would get more power due to the higher compression. As far is doing it, I say go for it. There are lots of people on here that don't care for it because its a good bit of money for not a huge HP gain, but it gives you tons of low end torque which I think is worth it (if I had the money, that is). Theres another guy on here with it and he loves it. I say if you want to do it and have the money and time, then go for it. Don't let other people talk you out of it.

you can run more boost on the turbo engine....you would make more power rather than na

You could prob run more boost, but you yould get more power on the same boost. And since this is a supercharger and not a turbo, where its pretty much a fixed boost, I think the NA engine would be better. Also, I think the Camden kit was designed for a NA engine as I don't see people pulling their turbos for a supercharger.

When you feel what the supercharger can do from a stock N/A you'll crapzor your pants, when you add a turbo onto a N/A you'll crapzor your pants...it's just a matter of taste and what you're willing to do/pay.

getting opinions on this subject is pointless.

the facts are helpful

FACTS:

-More people do turbocharging than supercharging on these cars.
-You have more availability kit wise and knowledge wise when it comes to turbocharging as opposed to supercharing which has much fewer people running them in these cars.

superchargers to me are not the best option due to the high price and lower power gains. a turbo would be my first choice, but for uniquness do the supercharger

Almost 90% of turbo rotaries make more power then NA .

Anyhow. I say honestly, build yourself a custom manifold and go with a direct turbo bolt on set-up.

OR

Just buy SonikRats kit until there are proven numbers on the Camden kit.

OR

Buy the Camden and work with something that isn't documented as much on the forum. So getting help would be diffucult in most circumstances. It will make more power yes, but do you have the CASH?

Hey,
I was wondering also on turboing my n/a engine or not. I know I would have to run it on a low boost and I would also have change the intake manifold and throttle body. I was thinking of running a bigger turbo than a stock 13bt turbo. I was thinking of a t4 or t3 then I would have a lower chance of blowing the turbo.I would really have to customize it plus I'm only 18 and need money.

If your only option for supercharging is camden, then the answer is a simple NOT.

Re-read what you typed then search.

Tech_Greek

If you're only 18 and need money, don't invest in either a turbo or supercharger, invest in mantience items to save your money up...

I have a little bit to splurge because I work full time...and trust me PAST the Camdens cost I would add about another 1k into the total, finished cost.

90svsidewayz

so if i ran a turbo engine with a supercharger and had a smaller pulley on it i could run even more boost without risking the engine blowing

SonicRaT

Yes, that is correct. HOWEVER, the 'turbo' engine with low compression will make LESS power with 'even more boost' than the 'non-turbo' high compression engine.

Say at 5psi for both engines, the non-turbo will make more power, probably the equivalent of 7 or 8 on the turbo engine.

But as I said earlier, the Camden unit is god awful, stay as far away from it as you can.

90svsidewayz

so your saying that a na motor would hold up better than a t2 would?

SonicRaT

iTrader: (6)

No, I'm saying it would make more power at the same boost. As for holding up, that's relative to your tuning abilities and engine design and all kinds of other factors.

90svsidewayz

well it would be easier to find n/a parts over the t2.

Jager

NA parts are far easier for me to find personally.

I've often thought about supercharging some time in the fututre because it's much easier to do than a turbo conversion, there's fewer parts involved. If you are into custom fabrication then you can mount a supercharger on the drivers side if you have no p/s or a/c, run the piping to an intercooler, then into the stock manifold. This won't be the most efficient manifold for boost I'd expect, but it would be a good starting point.

Roots blowers are bad, the camden kit uses a roots blower. They are inefficient and heat up the intake air quite a bit, which is very bad. Centrifugal blowers are much more efficient and don't heat the air as much, but provide less low end boost. Twin screw (or lysholm) superchargers are good, in that they provide the low end boost of a roots with the efficiency of a centrifugal blower. They are however much bigger than a centrifugal, making it much harder to fit it in an engine bay, that's one reason why in many aftermarket supercharger kits they use centrifugal blowers.

In the future some time I think I'll probably get a used centrifugal blower, make a mounting bracket to mount it where the a/c and p/s usually go, run a small intercooler either in the top part of the nose with some ducting, or in the engine bay like where the 3rd gen's is and then just run the piping into the stock manifold. That would be fairly simple and easy. I'd keep the boost to under 10psi so as to not blow up the motor. But that won't be for many years as I'm a poor student and I want a good suspension first.

I think superchargers are the way to go - you sacrifice higher boost levels for no lag but hey, how much boost were you wanting anyways? mo boost = mo power = mo problems.

I've been thinking about buying an eaton supercharger from a ford 6-banger and welding together a custom short runner manifold... mebbe this summer.

hey, how come no one has viewed my earlier thread today?! lol ~rich

Wanna buy an Eaton M-90? Got one here that's mint.

Ugh... Superchargers just don't work well on a rotary unless it's a twin-screw. Roots blowers are so damn inefficient that it's almost not even worth the time (Yes, this includes the damn Eaton M90).

Putting a turbo on is a LOT easier, considering everything is damn near bolt-on. Also, as been said before, a properly sized turbo can make just as much torque in the 'low-end' as a roots blower or centrifugal. So unless you've got an assload of money laying around, or happen to stumble accross a Millenia S charger, the only excuse to supercharge an rx7 is if you want to be unique and slow.
