boost control on a centrifugal supercharger Has anyone here tried over-driving a supercharger and then using an electronic boost controller and some sort of valve like a wastegate on a turbo, to control the boost? It'd give a flatter boost like a centrifugal supercharger with a constant speed drive. |
Re: boost control on a centrifugal supercharger That is very common nowadays. There was a Mustang article a few years back that essentially started the concept with a guy doing that very thing with a worked SBF running a YSI (see below), although it was already known that you could do that, it somewhat glorified it for the street racers. I know a few guys that run a Procharger F2 on their smaller LSX engines with the wastegate on the cold side, and it works extremely well... http://www.musclemustangfastfords.co...l/viewall.html |
Re: boost control on a centrifugal supercharger Thanks, I guessed it was possible and if it's possible someone will have tried it. |

Re: boost control on a centrifugal supercharger ProCharger just came out with basically an electronic variable over/underdrive to have some control of the boost. |
Re: boost control on a centrifugal supercharger Nice. I know I just learned something. Thanks for sharing the link. |
Re: boost control on a centrifugal supercharger I liked this idea I believe he said he got 70ft/lbs more out of the car http://www.superchevy.com/technical/...ger_wastegate/ |
Re: boost control on a centrifugal supercharger Sorry to bring up this old thread, but I have been researching this type of install and have a question about sizing of the wastegate itself. Seems there are only theories and no solid calculations to be performed, especially when one is used with a supercharger. From what I have found so far, it is essentially based on the amount of boost you need to release and the size of the engine itself, but haven't found any solid method to use in determining what the correct size that would be needed. Some charts give the option of 44 to 60 mm for greater than 3000cc, but I would like to be a little more accurate than that. Are there any calcs a guy can follow, or is it just a WAG? |
