Had a relatively successful day at the dyno today.
Wasn't expecting much more power as turbo can't flow any more really. It made 279hp and 309 lbs/ft torque at the hubs. With a 15% transmission loss I would guesstimate flywheel power to be 329hp.
Anyhow, that power is 8hp down on last time, but 30lbs up on torque. The good news is that was using less boost than before! Only 15-16psi. Before it was cramming in 22. Bad news is, the limiting factor was actually fuel and this is interesting because it either means my fuel pump is dying, I need a bigger pump or I make the current pump a 'lift' pump and mount a swirl pot under the boot floor with a stronger pump off that. The last option would be mor future proof.
Anyway, the results suggest this engine at a lower compression, P&P head and camshafts giving a higher lift will make the same power with less boost and this can only be a good thing.
More positives from today - my heaters are finally working and getting fully hot. I can only guess that there was a slight air lock in the heater matrix preventing full flow as it seemed fine on the journey home. The dyno fixed it!
With the new wheels and tyres on I asked them to do the tracking also. The car now feels much better than before, I reckon this down to the wheels and tyres. Ride is much nicer cornering seems much nicer and the car feels more stable.
All this said, I plan to actually use the car this year although I do have more things on the wish list, some of which will come sooner than others so no particular order:
New engine management! Capable of running the engine better with newer technology. I'm hoping to install drive by wire for the throttle after today's conversations.
New turbo, possibly GTX35 (above ECU and mapping will make this very driveable)
Adjustable rose jointed lower arms.
Triangulate the rear beam with adjusters to preload it and make changes to toe in/out.
Fuel pump and swirl/collector pot and new injectors.
4 pot brake callipers for the front!
All of the above amongst other things of course! Just got to rob a bank first :lol:
