Superchargers & Reliability?

[Simmoyo]

Hey guys, I'm thinking of taking the FI leap. As I'm told, a supercharger wont degrade the engine as much as a turbo... plus its easier to set up.

What would experienced owners say about:
- Reliability
- Fuel economy
- For a daily car?

Anyone know of a second hand kit and where to get it installed for a good price?

Thanks

I've heard the opposite.

If you use a positive displacement/rootes style supercharger, they develop boost from 0 revs, so the inside of the engine is always under higher pressure, as opposed to above 2krpm in a turbo or centrifugally supercharged engine.

Just means more stress on rods and pistons.

Most kits available are centrifugal, right?

Aren't centrifugal's the best? and if you don't always drive hard then there wouldn't be too much strain on the engine coz it only kicks in at high revs I think

A centrifugal supercharger works the exact same way as a turbo, but its driven off the crank shaft, as opposed to by exhaust gasses.

So it will have the same nothing nothing nothing BOOOOOOOOSSSSTT feel as a turbo. They also require the fitment of BOVs.

The most common (or rather, well known) kit for Honda motors is the J's Racing kit, which is a roots style that bolts up in place of the intake manifold.

Centrifugal kits for b series are avaliable, but tthey mount the supercharger near the dizzy, and run a driveshaft along the side of the rocker cover. Looks kinda ugly IMO.

Would that mean you'd need to get an intercooler if you got a roots supercharger and used it at say 10 psi?

I was thinking of spending 3k on a second hand kit + installation but it doesn't look possible with all the extra's lol

Stay NA, and beat those booster mofo's around the track! haha

An intercooler is difficult on a J's racing kit, because it needs to get sandwhich between the charger and the block. And sometimes there isn't enough room because of things bolted to the firewall.

But if you run too high boost, without one, there has been cases of getting so hot, it starts to melt and warp the head!!

yikes!

I recently put a Vortech supercharger in my car and I LOVE it! and your right, it works just like a turbo. The boost really kicks in at around 5-6k and from there on the pull leaves you giggling like a school boy who just saw his first set of boobs lol. In all seriousness though, as much as I loved my NA S2000, after going FI I could never go back to NA. I love having all this extra power. Im running a very conservative amount of boost (6.5 PSI and thats making 212 KW at the wheels!) and dont hammer it every time I drive it so Im quite confident that it wont do any real damage to my engine. Although I do plan on upgrading to bigger injectors in the very near future.

If you want some really good advice on going FI contact stevem355 on here. He's the guy who installed and tuned my car and he did a great job of it. He should be able to give you some really good advice
