What blow off valve is the Falken Silvia S15 running? Anyone know?

 

I though it was the Greddy Type R

 

it doesnt have one

 

fuck how didnt you know that

 

didn't want to get into an argument, but it sure has one, but can't figure out which one it is.

 

compressor surge.

 

Nope, that's not it

 

I guess they play into the philosophy of having "no lag" due to keeping the air in the pipe always pressurized?

I suppose the BOV is just ment to improve the life of the compressor section over the LONG term, so when you have unlimited budgets you can just replace the turbo mroe frequently and keep the performance benefit of always keeping the pipe pressurized between shifts.. rather than venting it.

However dosent this slow the compressor down signifigantly during the shift or lift throttle?? or with modern BB stuff the spinup is negligable and the real drawback in "lag" is actually pressurizing the pipe?

 

I question that, because when I put on my external wastegate it makes the same noise. I dont know why buy my Tial BOVsounds completly different then it did before at full throttle or if the wastegate opens (sort of a bird that is fluttering). If the wastegate doesnt open it sounds like my Tial always has.

 

the car doesnt have a blowoff valve
