This thread could go on forever, haha. I'll throw in my 2 cents. If you want a 10 sec drag car then either car will be fine but money is going to need to be spent on both to achieve that goal. Now I'm going to be seen as biased as I have one but I'd go the FG. I drove both when purchasing and the FG is much more advanced in handling and design from the BF. The FG turbo can easily be upgraded for not too much and the exhaust manifold provides better throttle response. As you can see below mine is making 340rwkw up from 254rwkw standard. So if you do buy an FG there is no reason why a gain of 86rwkw from standard isn't achievable with the right tuner and parts One thing you'll find is the FG turbo can come on very strong and therefore may not be the best turbo for a 10 sec pass as getting a clean start may be difficult. Not sure if a 10 has been achieved yet with a XR6T on stardard turbo? A bigger turbo like the 35/40 will be easier to get off the line and have more up top to give a better mph down the strip. So all in all I'd go an FG with an upgraded compressor housing. Benny
