06 Subaru STI With AMS HTA86 V-band Turbo Kit on the Dyno!

Contacting me from Mexico City the owner of this STi, Yared, let me know that his car just wasn’t powerful enough for him with his AMS 35r Kit. We came up with a solution for him.

Yared had his car shipped to us from Mexico where it was fitted with a new HTA compressor wheel, sleeved AMS shortblock, Cosworth heads, AMS front mount intercooler and a collection of other parts to get the most out of the car as we could.

We’ve calculated the output of our Mustang dyno vs our Dynojet dyno and this car would be making approximately 667 whp on the Dynojet. Congrats on the great power Yared!
