Hi everyone...I am new to the 914 world although not new to Porsche's. I have owned 3 944's and actually loved every one of them. I came across a craigslist ad for a v8 914 and well.....here it goes.. wish me luck ...any and all input is appreciated.
This engine is just set in place as mock up only...thats actually a 1966 283 out of a ChevyII I dont know why this radiator is where its at...going to get a race aluminum in the front lots of work to do here.. will have lots of parts to sale off of this project definitely going to need some more space for 12 inch wide tires..so probably won't look like this when i'm done |

I am taking all of the suggestions in....I also like the designing aspect of this as well..here are some theoretical numbers I came up with let me know what you think(IMG:http://www.914world.com/bbs2/uploads_offsite/i328.photobucket.com-17254-1397966474.1.jpg)

That calculator seriously underestimates what a turbo can do... My 1.8L Audi engine makes that much power with a turbo much smaller than were talking... Seriously... You put a nice big turbo on it and you'll make whatever the bottom end can hold... Its all about moving the power curve where you want it... Thats where sizing will come in. 350lbs tq at 2krpm is really plenty on the street, Where you actually will want that turbo is to start spooling ~3500 and then build the engine to allow you to rev to 7-8k (You've got nascar stuff... right?) so that you can rev it out and make some power (if you want...)... Traction will be the real issue when your getting to that much power... Much above 400hp its starts getting to be a real problem keeping the car straight. I've ridden in a 550hp v8 914 with maaaasive hoosier slicks, We stayed sideways till 100.... |
