Thanks, the awd will involve some serious design work though, my greatest concern is how far back the engine will sit and how much understeer it will generate. On the positive side; The subi engine is such a light weight! All of their components are compared to porsche. I will start fitting and figure out the options once the jig is finished and the car has been cut. |

I think you have more to consider than just the weight of the engine for the understeer/oversteer issue. The engine is indeed quite light, but how light is it compared to the bule of that extra long transmission that will be taking its place? By flipping the drive train around, wouldn't you need to take into consideration the amount of weight before the axles and after the axles? and the positioning of it all? How far will the trans go into the driver compartment? take for example the Diablo, they have the bulk of the transmission about even with the driver's posterior. I think AWD would be great to see, and I think you can shift a little bit of weight forward to keep your balance. |

You may lurk (IMG:style_emoticons/default/biggrin.gif) but my first measurements have told me the transmission will even stay well clear of the rear bulkhead, even in awd form with the cone attached. Aside from that, the bulkhead will be changed anyhow. with a slight driveshaft angle, I can even shift weight forward. I will also change the way to bulky sidebeams that contain the airhose, so my interior wil be wider, more spacy and I will need to construct a center tunnel that will again aid in strength...... What the hell am I getting myself into.....ah well......for the fun of it... (IMG:style_emoticons/default/biggrin.gif) |
