This car is no 700hp freak, but it's a pretty satisfying drive right now


I can be rolling about 10mph in 1st, nail it, and after a 1-2sec the turbos will spool and it will boil the tires, which is the kind of shananagins I was hoping for. Will be interesting to get to a track next year, it certainly drives like a 'big' 440 now but with the mellow little 383 the rest of the time. If I can eventually drop down into a smaller cam and add more boost I'll be quite happy.





Took it out for probably the last tuning session of the year. Moved to 26* timing under boost and was able to cleanly run it up to 5000rpm, about 80% duty cycle, so there's still some room, especially with my plans to add water over the winter, should be able to run 12:1 or 12.5:1 a/f under boost.


Back pressure testing

at 5-6psi
under 3500rpm back pressure stayed below 2:1
~4000rpm 3:1
~5000rpm 4:1

these turbos are very responsive on the street but the are definitely choking it up top. Seat of the pants rev time from 4-5000rpm is not that great. Maybe stage III wheels would be enough? Probably time to call a professional now that I have data....
