[Humble]

The wastegate is working fine but it may not be big enough as well as being in a bad spot. :P I've gone to extra lengths to make sure the motor can handle the pressure. There are drag bugs currently using a nearly identical setup on race gas and 40+psi so I know it can hold the pressure briefly at least. For TS turbos I've been looking at a slightly smaller borg warner than the one you are using or a similarly sized garret GTX.

As for the front bumper, it's coming together but I need some nice weekend weather to really get some work done. I need to do a lot of fiberglass work on the splitter and the airdam to get them race ready.
