My car goes for it's first dyno tune on wednesday.:nervous:

I've no idea what to expect, what do you think?
Running @1bar & 1.2 bar
ATW figs, I'm not interested in flywheel figs.

Here is the spec(bearing in mind I've built/tuned it:nervous: :nervous:)

RB30
ACL forged pistons
ACL bearings
Re-worked std rods
Balanced std crank
Jun 272deg 10.5 lift cams
Highly ported head
Single 80mm throttle body
800cc injectors
Tomei Fuel rail
HKS intercooler
HKS T51r turbo kit
HKS Hi-Power exhaust
AEM ECU
255 lph pump
Std 95 octane fuel

There are a few other things but there not related to engine performance.

Any guesses??

A T51KAI @ 1.2 bar will run approx 450/480 wheel bhp ( no run down bhp boosting allowed) IMHO. with around 460/480 LB/FT of torque , if it doesnt there is something very wrong.

@ 1.0 bar I would say 380/420 wheel bhp and around 400/420 lb/ft of torque

All I can say is i can guess very very well.....;-)

I don't know the limitations or the fuel pump, thats my main concern. Also, a std gearbox won't last to long with high torque.

I really want 550 lbs/ft(745Nm), but thats alot.

I might up the boost some more and see what happens.

I only have it set to 1bar, and that feels fast enough. Grip is an issue with the way the power come alive.

7000rpm is my limit, but the dyno figs will say if I need more, which I doubt.

Andy, are you really planning on only 95 octane? That's a significant constraint on what you can do with the timing.

The Silver Surfer ;) is probably in the right ballpark. Although I don't know what the ACL pistons will handle and AEM is akin to using a 186 processor :rolleyes:

The T51 will happily run upto 1.6Bar, especially if you put super unleaded in you tight wad!

95 octane is fine, then for extra safely I can run 98.

AEM akin to a 186 processor? They sent man into space with less than that.:rolleyes:
