Malcolm,
How do you go faster at the same rpm. Did you change the gearing also?

I had the same question. Possible answer: Just change to higher gear.

I suspect he meant he was able to accelerate faster from the same RPM.

Heinz,
I have only just come back to this thread. Thank you for your reply and I will try it out.

You could always drop the engine and replace it with a nice Omex Ford Duratec 2.5 VVC engine

The 210 HP version should be enough, but if not you could get the 270 HP or 290 HP version

I can certainly vouch for the two stage upgrade in performance for the standard GDI Plus 4. Mine is a 2016 model and whilst I wouldn't say that the performance was woefully inadequate it is true to say performance wasn't what I expected from a 2 litre sports car. I'm not sure what the difference is between the AR manifold/cat and sports exhaust and the Librands or the Williams manifold and sports exhaust. However as a first step last year I opted to have the Williams manifold and sports exhaust and I was not disappointed . Even without the ECU flash I noticed a more responsive take up with the accompanying pops and burbles on the overrun. The quality of the stainless steel product also had the added benefit of looking far superior to the factory fitted product. I waited a couple of months and then Williams returned my ECU to the factory who upgraded it to the Club sport specification. When that was refitted it really transformed the car across the whole rev range. I am not a technician so I cannot quantify the improvement in torque, acceleration and performance but I know it has improved to exceed my expectations.

Shiny! But is there a stud and nut missing lower left?

This morning I spoke with Mark Evans and ordered the Aero Racing exhaust. I pick it up on Monday 2nd September, so if you're making the café look untidy that day, watch out for me.

I think I'll also have the ECU flash, having spoken now with a number of people about it, but my plan is to fit the exhaust, then drive down to the factory to have the upgrade. That way I'll get a back to back comparison.

The other reason is, having looked inside the electrics box the ECU is buried under the body control unit, and the spaghetti wiring is everywhere and tight. I don't have a good track record with big multipin connectors, and so it makes sense to let the factory do it.

It may not prove to be a walk in the park either, because one correspondent who fitted the system himself had problems removing the old manifold, due to lack of space. So we'll see.

This will be really interesting, and it's quite an exciting prospect!

I must admit - I am a bit surprised that so much needs to be "done" to the Ford GDI engine?

It is used in so many Ford products (and is a fairly powerful engine) and seems to work 100%....so why all this faff (and great expense!!!) with the engine in a Morgan?

More POWER! :>)
