Supercharge website/ Discussion

In my opinion, there isn't an "off the shelf" supercharger kit for the b-series that's worth it.

As said above, the old roots type JRSC kits are highly inefficient and produce high IAT's which need the aid of either an LHT intercooler or water injection to run desirably. Increasing boost on them yeilds diminishing returns to power, with excessively high heat being the by-product (especially at high RPM's). Saying that, they do make a good basic power adder if boost is kept under 9-10psi, but their potential is limited on our engines.

Becuase of the above, a mate of mine in the UK tried a Vortech S/C kit on his b18c. As i've said in another thread somewhere, it produced nothing but headaches for him. When it did run without any issues, it produced a nice linear power boost. But the mechanism was a pain to install, it snapped three belts in three months, and the final result wasn't particularly spectacular. There was a noticably decrease in torque and power up to 3500-4000 rpm, which is not desirably on a daily driver. Essentially, this application wasn't right for his needs.

I reckon ewendc2r is on the right track. The rotrex system is small, compact and efficient and able to be intercooled - it's a step above in terms of technology against previous designs. But it requires a lot of custom work to fit. Saying that, there is a video of an ITR on youtube with a rotrex system (search "integra rotrex") - looks like a fun setup.

Awesome Vid.

I will let you know how it goes -- Essentially I will be relocating the Oil Pump, and getting rid of AC more than likely (because it doesn't work at the moment due to a **** up I made and I just deal with it, we have windows!). Putting the Rotrex where the Oil Pump is, short piped intercooler setup and 10psi should be good for around 280whp with max boost around 3500rpm -- This is fine as the B series is a high revving motor and if you want that power how often do you put the foot down in that gear or really, do you down shift? My biggest advantage other than added straight line speed, is the ability to short shift for more corners wihout worrying about dropping out of the power range.

Also looking at 16"x7.5" wheels ... you get the idea

^ agreed.

even though im a NA man at heart - i would much prefer a sc setup on a FWD honda to a turbo. I drove my brothers Gt3040 b18 integ and how gay is torque steer? worst part is that he couldnt thrash it around corners as all cornering ability goes out the windows once you hit boost...even though going fast in a straight line is fun - i would get over it wayy to quick

i would much rather have a 200hp+ hp integra/civic etc than a 250hp turbo integ/civic.

my 2 cents.

Makes perfect sense to me brother!
Cheers!

So for deivability on the Street/Track your recomending a sc setup? I am also looking into a JRSC on 6psi for my b16 (EG) can anyone give me an idea on the improvements it made? how drivability is?

Oil pump?

Thre is nothing magical about the rotrex...
What kind of rotor speeds are u going to be running to get 10psi by 3500rpm? How are u bypassing the additional boost? Of are you trying to tell me that your centrifugal charger is making the boost non-linearly? IS there a clutch system?

Just read the above post on the vortech. its exactly whats doing to happen with your setup, except the rotrex will be a little quieter.

The big problem about turbo hondas is that everyone wants massive power and massive revs. They arnt track guys, so all the purist (read: trying to justify money on NA mods that do nothing) get put off and pigion hole the FI crowd as straightline only. Use a small efficent turbo setup and u will get fullboost by 2500rpm, lots of predictablity, partial throttle response and still have plenty of revs to play with. Get urself a nice boost controller and play with gains, setup boost-by-gear and u can emulate a centrifugal setup without the parasitic loss. Its about area under the curve.

I just put together a turbo setup for a guy with a bluebird KA24DE. Used the biggest GT20 i could get my hands on. THis thing makes fullboost (14psi) at 800-1000rpm. Lots of torque, drops of quickly after 4500. Its an extreme case, but just showing u aftermarket turbo dont always have to be about 'tha peak powa outputs'.
