I had a quick question hopefully someone can help me out. I have a blitz dual drive bov on my sr20 and im not liking the whole rpm drop when coming to a stop. So my question is has anyone heard of these dual port systems where they V.T.A and recirculate? if so is anyone using one and does it make a difference to the rpm dropping? Any help would be greatly appreciated, Thanks.
I use these alot on VW’s which come with a diverter valves from the factory.
The unit works really well, considering the bosch ecu is extremely sensitive, and yet doesnt throw any codes or Idle rpm tumbles.
So yes it will work well on your car, But personally i would run a bov on your car, there is just some things you need to change on your current setup and you will not have any issues with a bov.
Pm me for details.
Can anyone tell me what I would have to change?
you would have to make minor changes to the pipe that your bov is sitting on, and also the plumbing would need to be modified a little also…nothing major.
Or just be a man and convert to speed-density.
How do I convert to speed density
In order to run a bov properly, you would have to put your maf inline, meaning it would no longer be on the intake it would instead now sit on the boost cold pipe and the bov would sit on the boost hot pipe.
Therefore any air blown off by the bov would still be metered properly by the maf and therefore cause no rpm stumbles.
Search my name on these forums i did my ka24de-t like this and made 350whp at 14 psi, many members on this board can attest to how well car ran.
Thank you very much
