Hmmm... Been a while between updates again!
I have taken this lil rig from blow through to EFI, maxed out the GT25/S200sx compound and just within the last couple of weeks installed a larger compound turbo pair.
New turbo setup being fabricated as usual by myself in a hurry in the shed...
Dyno day a week ago. We had trouble in that we couldn't keep the boost lower than the 5 bar map sensors max of 60.9psi... The engine was still happy as a pig in slop however! With the ECU doing the overboost cut thing we saw 440rwhp.
So during the week I pulled it all apart again and mounted a 60mm wastegate in place of one of the 38mm gates to help keep a lid on the boost until I can get a 7bar map sensor. That .led straight to Saturday just gone with a half mile roll racing event on an airport which I had been invited to compete! I took a few runs to start getting a handle on getting the best from the new combo and once I did it was trying to eat me! Power delivery is extremely savage and I have not quite gotten traction control settings right yet so according to spectators and officials it was spectacular to watch. The old girl did bring home the fastest 4cyl over the half mile however!
Cheers,
Jason
