Turbo swap or new car, that is the question...

Quick update.

I put the recirc valve back on and the driveability is much improved. Whether that is just due to me knowing that it is back on and how it should be working, or a real improvement, is largely irrelevant. I feel better and smoother driving it.

While I was there, I wound the wastegate arm in a couple of turns, really easy to do!
More boost, leading to more top end and (more importantly for me) midrange.

I am booked in for a checkup dyno run on Friday, hopefully with a fit curve...

Good result!

I'll guess at 229 hp at the crank)

That's a good way to start the morning, a quick local dyno run!

Not all good news though, only making 206BHP at the crank and something is still not quite right.



The boost pressure also follows the torque curve, with a peak of 14psi and falling back to hold 10psi.
So there is a bit of an overboost. Could this be due to adjusting the wastegate arm and the wastegate not being up to holding the pressure?

Any ideas on how to improve the car further, without lots of spend?

You are welcomed, sir, to the never ending pursuit of 'steam horses' (HP)!

At the moment, I would be happy with a correctly working standard car!
More horses and 'torques' would be welcome, but I know that the money is just not there.

fair do's at least it is heading the right direction though

I was a bit disappointed that my R5 made about 120 hp at the wheels, supposed to be 160 at the crank. I guess after a few decades those horses escape without loads of work

I thought 10 psi was standard boost or there about....

your actuator is probably a little tight if it is over boosting & then settling down to where it should be...
