so everyones got all these mods to their n/a but anyone have a supercharger on an fc? just wondering about opinions on the dif between that and a turbo, if anyone has one??

SureShot

Supercharger will give a little more mid band torque.
A turbo will generally cost less & give more peak HP.

rarson

A properly-sized turbo can give you the powerband you want while being flexible and easy to adjust, though a supercharger would probably be easier to install.

Another plus for turbos is the muffling they provide.

evelhalo

not really worried about install, but im runnin an n/a, wouldnt the supercharger be a more intelligent/ cost effective "bolt on" upgrade, as opposed for the time/$$ req to add on a turbo.


Basically im tryin to decide wheather to run some kind of sick port with a supercharger, or if i should just save my $$ and buy a TII motor?

obviously lookin for opinions, just fyi, i love fast cars, but rarely go to the track so reliability is a factor as ths is my dd

If it's a DD keep it NA IMHO.

But if you want boost it depends what you really want:

TII is overall easier to do since it's been done like 9,500 times.
More power in the long run.
Possibly more reliability.
Alot of cost for everything to go smooth and do the swap "right", right IMHO.

Supercharger (Camden since it's the only one on the market):

Bolt on to your NA block, so you now wouldn't have to buy a j-spec and rebuild it.
Alot of your current modifications will carry over.
Possibly less down time due to the fact you should get everything at once instead of peicing together a swap (buying a TII is always easier).

I wouldn't do it man... the cost to power ratio is not in your favor...

To be honest I can't see how Camden sells anything... You could almost get a TII for the price of their superchargers

RX drift

can you drop a s4 TII in a S5 na car with out much prob.?

Jager

iTrader: (10)

It's because people like to be different and want a straight swap onto their pristine NA's or the like.

Not everyone wants a turbo you know. It's also a matter of preference.

camden currently has a supercharger for the 7 with everything included for $2,599 i have the info at work ill post it tomorrow

I current have a S5 Supercharged FC. And man is it fun, its faster then stock T2's and Rx-8s.

Here is a thread with the install:

That's for their charger alone to be used with a carb.

It's $3700 for their full kit with the manifolds and such.

YES Camden FTW! I see you got your FD already...

I heard they were fun to drive. But exactly how much HP do you really gain? For under a thousand dollars you can get a stock TII to well over 220BHP with just an exhaust upgrade, and FCD.

I know SC's are not making that kind of bolt-on power.

really just depends on the pully, I was only boosting 6psi at the track and was walking stock T2's and RX-8's.

I'm sure with a over drive pully boosting 12psi I would be able to walk slightly modified T2's and maybe stock Fd's.

And its really a preference issue.. if yuo want big power.. go with the the turbo, a proper turbo setup will make alot more power at the same boost levels.

But the main advantage of the Super charger is the instant boost responce, when coming out of corners, I can just get on it and be off.. not have to wait for the turbo to spool to build boost.
I think this would be a prefect setup for people who do auto cross because of the instant responce.

Makes daily driving fun too.. hehe

no thats the full setup but for fuel injection not carb here are the links

5" would be to small for a 13b.. unless your only shooting for 4psi or so.

I'd get at the very least a 7"

royaltrex7

4 psi would be a decient increase in hp at first then go to a 12 inch

trainwreck517

iTrader: (1)

For the money spent, at 4psi you will be very disappointed. If anyone is going to do this, don't get cheap. And just go with at least a 7"

royaltrex7

true

Ok, lets do the math here. (Conservative)

Average NA, stock ports, good condition: $2000
Supercharger kit: $3700
Full exhaust, Racing Beat: $900
Total: $6600 Total HP: 210-230rwhp

Average T2, stock ports, good condition: $3500-4000
Full exhaust, Racing Beat: $789
FCD: $90
SAFC2: $115
GReddy 720cc injectors(secondaries): $225
Total: $4719-5219 Total HP: 220-230rwhp

Now...sitting at this point...the supercharger guy is making about equal horsepower, for about $1300 more. Also, the supercharger guy is about near his end for more horsepower.

With that $1300 saved, the turbo guy could go and buy a BNR Stage 3/4, get some 1600cc injectors, and a fuel pump....and suddenly the supercharger guy is 150rwhp behind.

You make the decision...

Jager

iTrader: (10)

Where do you find a SAFC for $115?

Also, keep in mind the fuel requirements for the supercharger.

Supercharger kit (10psi pully): $3700
Full exhaust, Racing Beat: $900
SAFCII- $200
550cc injectors- $40
720cc injectors -$70

T2 Swap,

T2 hood: 250

That seems a bit more fair.

The SC will cost more, from a turboII thats slightly modified. Thats a given. A turboII will also make more power with with less money.

But will cost almost the same from a t2 swap..

But the main reason why I went SC.. is well I wanted the INSTANT throttle responce!
Which is very helpful in road racing, and auto crossing.

At 6psi I was able to pass up stock T2 on the straits, and catch up the modded T2's in the corners.
Coming out of the apex I would have full boost resulting in faster exit speed.. which really helped with my times.


Alright, I think thats enough for now.

Wow, if you're paying 2 grand for a Jspec, you are getting ripped off. And why would someone buy a Jspec just to spend another 1800 to rebuild it? IMO, if you're just dropping a stock engine in, and you buy from a reputable dealer, then the rebuild isn't necessary.

Also, your fuel pump and exhaust numbers are too high. A straight-up TII swap is easier and less expensive than a decent supercharger setup.
