Hi

Does anyone here run Blow Off Valves?

 

[Mr.Spool]

yes been around many cars that run them
What would you like to know.

 

[J-B Racing]

I was just asking.
thanks for responding

Hi

Does anyone here run Blow Off Valves?

Fun Fact,,, i was in a pit 2 weeks ago with a friend who helps out with a car running a huge single ,114mm i think, he has removed the waste gate and controls boost thru a b/o valve and a fuel tech 600,,and it seems to be working pretty well. Second time out car went as quick as it ever did. I'm very intrigued by this arrangement.

I just picked up a used Precision SLIC that came with an up pipe and BOV attached. I wasn't planning on running it but curious on the opinions of this board...

 

[Mr.Spool]

You dont need the blow off valve with the new turbos as most of them have or slots in the compressor cover.

We run 2 60mm gates to properly control boost on a 102mm@2300hp
Through say 5 stages.
the log shows precise control over boost.
I cant even fathom boost control via a blow off valve.
Would need to see a log and with stage intent to believe that would work precisely with gate response actually measured.

Turbocharged 4,779 WHP: Can Mark Micke make turbos great in Pro Mod, again? < is the title to a UTube video that is pretty shocking and explains some of how it works for the FuelTech deal. I agree that w/gates can do a perfect job,,however this system seems to have less moving parts?​

Interesting deal
The fuelteck is an awesome system alot can be done.
the electronic gates have incredible speed.
I know what those guys are trying to do as its seems to be so tough keeping up with the blower cars.
Closest we have come to the idea of pulsing a blow off valve is sealing the wastegate shut with good traction control.
There are many downsides to that though.

There is a Turbo Buick road course car that plumbed the BO Vv. discharge to turbo inlet to improve response.

Think Greg Wahl in British Columbia Canada runs one
I’ll try to post up a pic
