Well we always like more power. For some reason we could not get more than 15psi which was limiting power, so if we'd solved that on the old engine we could have made more.

So if we can run more boost we'll make more power. But the main advantage is better fuelling control and launch and traction control.

I'm sure you wont regret ditching the SU!

this is going to be a great addition to the car, I imagine the ECU can map boost too which should be usefull,

Is this a special small vave head for the 998?

Relatively small valves, 33/29, same as the old head.

I don't think so, the numbers predict a little over 170bhp.

155 bhp on 5 port and 15 psi
200 plus on 20 to 25 psi 7 port is viable .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Traction control should tickle your balls a bit on the start line..

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

I don't think we want to be too optimistic. It is only the start of the development for the 7P so maybe 200 in a few years, but to get 170 now will be good. As I have inherited the old engine I am keen to keep up and hop to push that a little further and finally get to the bottom of the 15psi limit.

To your knowledge, what was limiting boost on the 5 port setup ?

Not sure. It was suggested that the wastegat was blowing open. Now we have a 15psi actuator, so it seems unlikely that this was happening at 15psi.

However, we had a chinese IC that has been shown to have high pressure loss. so 15psi at the plenum could have equated to 20 or more psi at the turbo.

Both engines have new ICs, so we'll see.

Yes. Last evening I went in to the garage planning to tinker for 1/2 and hour. 2 1/2 hours later I emerged with a mould for the plenum. I usually get changed.

Don't worry about the trumpets they are just stuffed in with bog rolls to help me get the shape.

When done the mouth of each trumpet will be inside the plenum. throat length will be around 200mm.
