so in theory its just a crude dump valve? i'm just wondering if this is causing my engine to draw in too much air, can they corrode or leak? tbh i never gave the plenumn any thought when i bolted it on, i thought the only poppets where in the butterfly. 133.5 bhp 123 lb torque 116mph @6640rpm 9.5psi

so as that when the butterfly closes the popet opens and a small amount of air can still go through on over-run to reduce compressor stall.

The poppet valve in the butterfly is to reduce hydrocarbon emissions on overrun, and was fitted to NASP HIF carbs as well. |

the turbo carb rebuild kit has a butterfly without the valve thing, most people have rebuilt there carb and used the new one, my engine works fine with the new butterfly and it must be less of a restriction |

I have had the butterfly, without the poppet, on the carb for four years without a problem. IIRC Burlen don't make the butterfly with the poppet valve, so all you can get is the plain butterfly. |

if you change the spring for the montego turbo spring you will be able to run up to about 11psi. Does anybody know the spring rate of this Montego Turbo spring ? Thanks in advance Rusty by nature
