  • CRX vs. NSX street race video

    http://www.buzzhumor.com/videos/987/CRX_vs_NSX_race

    I do not agree with street racing, but this is a good race with a surprise outcome. Oh ya, the CRX is heavily modded, FI + more, probably turbo, you can hear the turbo spool up, and the BOV at the end.

    mkay - rather strange for a first post....

    what kind of jackasses race on public streets like that anways...

    I bet you're the guy with the ghey gold trimmed glasses too hu?

      FI? Do you mean fuel injection? There hasn't been a honda motor without fuel injection in decades... Every new car made has fuel injection, so that's certainly nothing that makes a car better/faster/unique.
      Have you looked in the FAQ yet?
      How about the Wiki?

          I guess I'm just a ricer n00b.

          I don't think that's really a bad thing, though.

            Actually this is his second post. His other post was of another video on the same site. Any bets he is advertising?

                Well, I think I will jack this post... Seems like people here know a thing or two about little turbo cars... So, that cool sound from turbos after they wind up comes from the BOV (blow off valve), right? Is that the same thing a diverter valve? I have a 2003 A4 1.8T that I want to do some work on down the road, figured I take (steal) this opportunity to ask about BOVs...

                  almost the same... it's the same part as far as i know, but modified to be a BOV. I have a baley DV if you are interested that i wanna sell... I have a 1.8T Passat Same engine baby...

                    Shame the video is too short, I wonder what happened to the race after 120+ mph.

                    This remind me of that ****y clip with an F1 car against a jet fighter, what a joke.

                      So does the diverter valve not make the cool "ppsssffftt" sound? Any performance gains from doing it? I think I read somewhere that it decreases backwash and therefore reduces some turbo lag. I seem to not have as much of a quick kick when i step on the gas like i was used to with my old eclipse gsx ('90 & '91). Other than doing the ECU reprogramming, what other mods are good for a little extra power, but not a ton of cash? Oh, and someone can flame me anytime and tell me worng post, wrong group, or whatever... I can take it....

                        The blow off valve, i believe, is our term for what we call a dump valve.

                        this is located in the engine inlet (compressor) side of the turbo as oposed to a wastegate that is on the exhaust (turbine) side.

                        The wastegate is triggered by a mechanical pressue swtich (eg a calibrated spring and a lever) so that when a set compressor PSI (boost) is obtained it leaks air from the turbine/exhaust side to prevent the turbo spinning any faster and going over this pressure rating. A typical setting would be 10-20psi going from stock to tuned levels. 14-16 is normally a max before engine mods are needed such as uprated intercoolers and strengthened components on a typical engine.

                        It is the wastegate you adjust on an engine to up the boost. They can also be electronic and controlled by the ECU letting you 'up the boost' via the electronics.

                        This device is there to prevent over boosting which will blow the engine and over-revving the turbo. Turbos are very highly stressed components due to high temps and pressures and the high RPM speeds necarssary.



                        Back to the blow off valve/dump valve

                        This device is there to prevent the turbo slowing down when the throttle is closed and the air is not needed - ie when you lift off to change gear.

                        A turbo consists of a turbine, in which exhaust gases enter the outer edge and expand exiting the middle of the centrifugal blade and then continue down the exhaust joined by a shaft to a centrifugal compressor blade in which the air enters the middle of the blade and is compressed, leaving the blade at the outer edge. Therefore when the throttle is closed and the airway is blocked then the air leaving the compressor side has no where to go and will stagnate (back up and stop). This will cause the turbo to slow down. The blow off valve uses the high pressure of the air stagnating to trigger it and release the pressure and a lot of air (hence the woosh noise that ricers love to here when they lift). This air escaping therefore stops lag b preventing the tubo slowing down so when you next open the throttle the turbo is still already spinnign quickly and close to, if not on, boost.
