Hahahaha... Oh man, I bet all the Lamborghini driving pigs down there would never see this car coming. Last time I was down there I must have seen 15 gallardo's, It's nice to see a Florida tuner doing something big. Congrats guys! *two thumbs up*

Hey, awesome work there SDR. I have a suggestion.
Have you ever given your BOV serious thought? THE OTC stuff u get, looks nice , sounds nice but causes gear shift boost lag. Perhaps you could consider an upgrade to the BOV, by adding a BOV electronic controller to perform BOV action before deep vacuum. Remember those BOVs have to HOLD shut vs average vacuum so their sensitivity is compromised by having to wait for deep vacuum or risk leaks. In any case no mechanical BOV can react as fast as one driven by an electronic control because the e-control can start to perform blowoff before vacuum. You have 2 options: 1) Keep your BOV and have the e-control manage the vacuum control line to the BOV 2) Replace your BOV with 2 N/C solenoids (for hi boost and safe redundancy) placed to minimize air flow reversals. Option 1 is a bit simpler but option 2 will yield better results. Both achieve pre-vacuum blow off. Option 1 does this by having an additional check valve inline with the BOV vacuum and e-controlled solenoid, the line between the check and the solenoid will be larger than normal to act as a vacuum accumulator. This requires some line length tweaking to make sure there is enough accumulator vacuum to operate the BOV before vacuum is recharged by the intake. Option 2 entirely replaces the BOV with a pair of 1" VITON solenoids.No vacuum required. The e-control fires those solenoids as soon as the negative Delta pressure change triggers it. So if u're running at 25psi and lift, by the time u're on 15psi in the intake the solenoids are opening. With both solenoids opening, one placed near the throttle plate and the other near the compressor, your turbo does NOT spool down much, except due to reduced exhaust gas outflow, which is momentary, nor does your airflow suffer compression wave velocity slow down or possible reversal. What do you think? |

Sounds good.. Allot of people over look their BOV applications when at the track. in japan they dont run BOV in ther race cars. when we go to the track the bov will be shut all the way but your idea sounds interesting... send me more info [email protected]
