Supercharger...

You shouldn't be getting that with a turbo SR20 anyway. Our cars use a MAF and the post turbocharger air has already been metered, so it should be recirculated rather than just blown off.

are you saying theres no point to put a louder blow off valve? i hope not! thats why im getting my DET! jp

I think another possible reason is the parasitic loss with the use of any supercharger. Turbos are nice for 4 cylinders because it doesn't rob as much power from the engine as do superchargers. But then again the 1.6L Civics have a nice roots from Jackson ... so ...

Let us not forget about the mighty Vw G60 Corrado. I had one and it was mighty powerful. Alot of extra torque was given by that little charger cause it would have been near to impossible to get that much power out of a 1.3L engine. Mind you I had a turbocharged '89 probe GT and that had more quickness off the line than anything I've owned b4 so go figure. I'd personally go Superchrged if they mad it available for the sr20de(S)????
hehehhehe

On a less technical note, try putting your hand in between the chassis and pulleys (engine stopped, eh) and then consider then logistics of fitting a drive for a supercharger in there.

Dude, you need to do some more research.

A turbocharged SR20 should have the compressor by-pass valve recirculated back to the intake just before the compressor inlet. It should not be vented to atmosphere. Luke is having some issues with this.

If you are buying a DET to have a loud BOV, well......

Now for some definitions:

Blow-off valve: vents to atmosphere
By-pass valve: recirculates

The two definitions often get screwed up, but you should not use a blow-off valve on a turbo SR20. By-pass valves are usually very quiet. Bummer huh? Now I guess you're not getting your DET?

But, with a properly sized turbo connected instead of the SC, it would kick the SC's ass.

so its mostly honda engines polluting the air? no way am i still passing up the DET! its ok, they will just have to see me leave them in the dust and then theyll realize i have a turbo and does this mean that there is no blow off valve at all, but instead the bypass valve takes its place?

There's no pollution involved since it's just air that has been compressed by the turbo.

BINGO! Some people call the by-pass valve a blow-off valve (including me on occasion), but yes, the by-pass valve takes its place.

The reason for recirculating the air is that it has already been measured by the MAF so the computer is counting on it being there so it gets the mixture right. If you vent it to atmosphere, the ECU will provide too much fuel for the air in the engine.

hmm... ok i understand now, i guess honda engines need the blowoff valve since they dont use a MAF.

I believe you are right ... I think Hondas are speed density systems.
