barnett468 418 Report post Posted January 10, 2015 it depends on how low your vacuum is . . the abs electric master works no matter what. Quote Share this post Link to post Share on other sites
Glenn83 19 Report post Posted January 10, 2015 I'm not sure what my vacuum will be exactly, it's 408w I have it screwed together sitting on the stand at the moment, hopefully I will have run on a dyno very soon. It has a pretty healthy custom solid roller cam, 672/650 lift , duration 236/248@.050 and 110 lobe separation. I have been leaning toward the hydroboost but still open to options.

barnett468 418 Report post Posted January 10, 2015 ok, well most likely just adding an extra vacuum can won't be enough for low speed driving . . my guess is you will have 12hg at the most at idle . . the hydroboost is ok as long as it does not spring a leak or somehow fail, but it has 2 hydraulic lines that need to be routed in your engine compartment away from the headers. the electric master from abs is clean and simple and a vacuum pump is another option.

Glenn83 19 Report post Posted January 10, 2015 I agree the abs system is a clean looking setup Quote Share this post Link to post Share on other sites

I suppose they could have blocked you, that would definitely have improved the forum. LMFAO! Quote Share this post Link to post Share on other sites
