Superchargers & Reliability?

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

Haha love it JamieP, thanks. I'm amazed at how much you got with only 6.5 psi! Do you notice any benefit at all in the lower range?

I'll contact him for sure, how much did it all cost you if you don't mind me asking?

Oh definitely, its a lot more responsive in the lower range now as well. vtec also kicks in at 4 k too. But when you hit that higher rev range, you really feel it pull like crazy!

To do it right, its not a cheap thing to do. Originally I thought I could just get a cheap kit and install it and thats that. I purchased my kit for a bit over 4 gs shipped here from the states. I also purchased a haltech platinum computer and had to buy a few extra bits n pieces like oil lines etc etc. all up I spent just under 9 grand

Wow... Do you think you'll ever need to upgrade the diff, axels, drive shaft... or can they handle it

**JamieP** · 02-11-2011 03:47 PM

nah, they can handle it so long as your not being an idiot and doing heaps of hard launches

So much misinformation in this thread..

Jamie is right though. I had over 300KW@ the rears. Good fun. So much fun I lost my license in the process.

Prob already been said before but reliabilty is all in the tune then its all up to how well you maintain it. The more power you make, more maintenance is required. I think its safe to say you will not regret it. Once you go boost you wont go back

Instead of just saying that, explain what you mean.

Hey, it's OzHonda!!!

Seriously though, you can pretty much ignore all of page 1.

All FI solutions push air. Whether or not this is additional strain on the engine is not a result of revs, but throttle position. If you're not WOT (whole open throttle) much of that extra air will be vented off by the BOV (or bypass valve).

Also, I think someone is getting confused between J's Racing (Japanese tuning house) and Jackson Racing (US company formed by the Jackson family). To my knowledge J's don't make an FI kit and certainly not a PD supercharger. Jackson made several for the B and D series engines but not for the F20C. There was a PD supercharger for the S2000 made by someone but I don't believe it's in production anymore.

A centrifugal supercharger is driven by the crank but due to the scroll like design of the centrifugal compressor produces boost in direct proportion to RPM. At low revs it produces very little. At redline it produces it's maximum output. This is not ideal for the S2000 as it has such a long rev range. If your centrifugal SC produces 6.5psi at 9000rpm, at VTEC changeover point (6000rpm) it's probably only producing 4psi.

If you see this as a benefit we'll have to agree to disagree.

Contrary to popular opinion the 'nothing, nothing BOOOST' idea of a turbo is incorrect or at least outdated. If you purchase a properly sized turbo for your application you will not even notice the supposed 'turbo lag'. Even the Greddy kit (basic, but out top-ends the basic Comptech and Vortech kits) is at full boost by about 4000rpm. My ball bearing GT3076R peaks at 21psi but producing 16psi by about 6000rpm. Turbo lag my arse.

So basically my turbo produces way more top end than any of these kits, and has a much bigger midrange, yet unless I choose to put my foot down (and I often do

) puts no more strain on the engine than NA.
