Guess what, I only dyno'd 299.6 on a Dynojet - nowhere near 346. If you go by my ET of 12.30, it says I'm making 359whp - oops, even further off from reality.
What gear were you in when you crossed the traps?

What gear were you in when you dynoed the car?

If they are not the same, your comparison is pointless.

Although no one knows how you magically went from 123 to 127mph traps, and although we haven't seen you duplicate it, 127.xx mph still only equals to 480-490whp, not 540whp. And when did it become a daily driver? It sure wasn't in the past.
The only reason the car would have to not be driven is when it is being worked on. It is an '05 with 21000+mi. You havent seen duplication of the trapspeeds as I have not been back to the track. Engine dampers have been giving me the latest trouble. First Ati, now the stock one is broken.

Are you guys saying that a BOV that is recirculated behind the MAF will still hurt the performance of the car, or are you referring to people that just slap a BOV on and vent it straight out?

We also lump all diverter valves and blow-off valves into the term "BOV", so I'm sure you just got confused.

I preffer the Term ABV for Air Bypass valve, So If you see me say ABV, I mean a Recircluated BOV. If I say BOV it means It VTA, Vents to Atmosphere. I got more Personal lingo I should put all my abreveasions in my sig.

Words are for noobs.

I'll be going with either the Forge RS or Evo15 DV pretty soon. Hey Scott, does TTP offer any specials for Evom members? Sorry about the OT comment.

BOVs can be bad when an incorrect type is used. For an Evo with a MAF sensor as they come from the factory, stick with a recirculating BOV. Don't waste your money on this mod unless you really need one. I'm kinda bleh about having to buy one, but you gotta pay to play. 30 psi is a bit too much for the stock metal DV.

No one is snapping. Reread the thread. You asked a question, we responded "no"as in "no its not a problem to recirc, as the factory has done".

I don't why people have such a hard time understanding blow off valves (CBV).

Yes I have them both Andy and yes, the pricing on evom is better than from our site in many cases from discounted pricing and/or free shipping arrangements. Let me know what you need sir.

This is wayyyyy of topic but if you do a search on Google video. look for Turkey Blow off valve. these kids in an gen 2 eclipse duct taped a turkey call to the BOV and he keeps holding 4th and letting it out and omg.. its the funniest thing ever. he drives around malls and people reactions are worth $1,000,000.

BOV FTW!!! nothing like showing off your turbo!

If your bored and want to know what i am talkin about.
