Interesting. Does EFI cause crankcase pressurisation? My efi doesn't. |

Cheers for all this info, I was just looking at the Edelbrock as an idea as reading about it it operates in a different way to the Holley 390 (which I used to have fitted) in that the secondaries are not just vacuum operated but part mechanical, not sure how this is a plus point or not but I read about a guy in NZ I think it’s as who head one fitted and reckoned on it being a good unit. Having said this, the idea of FI is probably a good one except the restrictions of the standard manifold probably weigh against any advantages. I looked back to at some previous comments on the SOC site and Stagmuffin I think it was said he ran the Holley through a catch tank back into the air filter with no problems at all which is (excluding the catch tank) how Tony Hart fitted the Holley to my car originally. Cheers A Freinds stag had the eldlbrook 500 on it and made 93 bhp on a rolling road day at enginuity. Probably partly because it was fitted straight out of the box with no setting up or tuning. Which is the problem with a lot of these " works straight out of the box ideas" different fueling needs money or if you can do it yourself, time spent on tuning. |

Interesting. Does EFI cause crankcase pressurisation? All my Stag engines using efi (4 of them) have to be fitted with a PCV system to prevent leaks
Anything that creates more power will create more blow-by on the rings and without another form of suction to replace that generated by the Strombergs every tiny hole will leak. Sometimes I get lucky for a while.
