The competition claims to be running #10 boost on a GT45 on a 1.3 motor. Why on earth would you run such low boost on such a small engine with such a large turbo?

 

thats a 10sec car a 1.3L but a v6 class

 

If you are referring to the FC RX-7, the 13B wankel rotary is a whole different beast altogether. It isn't really a 1.3 liter, the way the wankel works it is more like a 2.6 liter. 10# of boost on a 2 rotor with that turbo can make some big power. It probably makes close to 500 wheel, easy 10 sec car.

yeah what he said!

 

gotta be a rotary...rotary engines put out crazy amounts of exhaust gas so it can spool far larger turbos than a piston equivalent.
i myself have a rotary engine with a T-72 with a Q-trim 1.15 turbine housing and i see full boost by 5500rpm.

 

Just saw the show couldn't belive full-race lose like that, there negotiation should of been better.

 

our car broke, we lost the race. tore a coupler, had a boost leak, lost the car there is a long writeup on our website, check it out if you are bored:

Geoff,

The powerband on your 790whp dyno graph is insane. That car is going to fly!
