I've been custom dynoflash twice. The first was with turbo xs rfl bov. I try swapping it with a 1g bov and the butt dyno says it's not pulling as hard. I thought it was the flash so I recustom dynoflash again with the 1g bov. It seemed to pull a little better. I swap back to the turbo xs rfl and butt dyno says it's pulling harder. I like how the car pulls with the turbo xs rfl but the the drivability sucks. By the way I'm recirculating the turbo sx rfl.

Anyone know why I'm feeling or seeing the difference? Is my 1g bov bad/leaking? DO I have a leak somewhere else? Anyone else tried the swapping bov and did you felt any difference?

I tried using two bov but it didn't work.

Thanks.

 

sounds to me like the 1g is leaking

 

Yeah I'd Say Your 1g Is Leaking. How Much Boost Are You Running?

 

Boost is around 20-21 psi. How do I know my bov is leaking? Tampering of boost? Could it be a minor downpipe exhaust leak? Lower intercooler pipe leak. I forgot to mention that the car is bascially BRS4.

 

Any more suggestions/comments?

 

run a leak test on your setup...

 

The thing I don't get is that just by swapping bov with no other changes the butt-dyno is different. The 1g seems to hold boost fine but the torque doesn't seem to be there.

 

I now have the Forge RS bov and the driveability is awesome. Car seems to pull great but my brother drove the car and he said that the car is not pulling as hard as before (butt dyno). Boost hold 20-21psi. This is with the turbo xs rfl bov vs the Forge RS bov. I've tried the 1g and hks bov.

I don't know if there's a leak somewhere but it seems like my car pulls harder with the turbo xs rfl and I'm stump

Anyone tried swapping out bov for testing??
