Polishing is going to probably add cost to something you are not going to see very much of. I'd rather see more put into a nice replacement hood or reduce the price of the overall kit.Alright guys, here's the official word on head shimming from our Andrew, our engineer: With the Mav, any 91 octane pump fuel turbo setup (always use high quality 91!) will require compression to be lowered, either via a head shim and/or low compression pistons. Stock engines are fine on E85 for low boost, and if you're running race fuel you can run higher boost on a stock engine- we're estimating 8 psi on VP's 110 race gas, and up to 14 psi on VP's 115. We are currently discussing options for what will be included with a low-compression Aerocharger turbo kit; our priority has always been to deliver the most complete package for a comprehensive install.
On another note, here's a pic of our air/air intercooler production sample that just came in - this option's going to come with a custom ram-air hood scoop. We'd like some feedback on what we should do for finish options, should we polish it off or leave it looking rough and industrial?
