Hello people.
I'm a noob here, but been around cars for awhile. Recently acquired a 75 914 that is very clean and going to do the Subaru conversion. Car will be used mostly for track events and some odd miles on the street. The question that I had, is how does this car respond to high horsepower? In stock form, the EJ257 will put out 300 at the crank and I'm wondering if it makes sense to tweak it a little more.... I've seen a few conversions done here and read through a ton of threads. Some very helpful info here, but I haven't read anybody's feedback on what the chassis will do if throw 500hp at it? Besides all the supporting mods necessary to handle the power, what will the driving dynamics be?? Maybe it's not worth to do anything except just the engine swap, but since it's going to get a full cage, big brakes and aero, maybe go big (IMG:style_emoticons/default/driving.gif) David |

300 HP is a VERY fast car. Start pushing 400hp and you need to get some serious tire under the car to keep it on the ground. at THAT point, you need a strong trani/cv's. Which you then need to reinforce the chassis quite extensively, a cage will do if its tied into the correct points.
Suspension for a 500hp car? At that point most of the race cars have some custom suspension. Typically you just need to determine what kind of driving you'll do and tune the suspension for that. IMHO with a turbo engine this is the way I would go.. If you have the money, build the engine for 500hp, Lower the boost down so your at 300hp. Drive it for 6 months. Add 50hp. another 6 months, add 50more.. ect. You'll respect the car more and you will learn what changes are needed as you go along. |
