A bit of a long update.
On Thursday we loaded the car on the AA and drove the long way to the RR.
First impresions where lets say toooo optimistik.
At first the engine was running too lean. We talked and talked about the route to take on mapping or not the standard Ecu and at the end we came down to the conclution that its not neceseary to do so.
Probblem solved partialy with the use of a new fuel regulator. All the multiplex XU engines use a 3.5bar reg so we went down the road for a new one from Bosch at 4.0 bar's.
Now the initial chocking when bliping the throttle is gone and the engine pulls even harder.
At the first RR session my baby return 227hp on the fly but i believe that this figure is to optimistik as now the engine is running a bit rich.
Dont ask me about torgue fig yet as the finnal run is not completed yet.
The quyes ordered a new aftermarket fuel pressure regulator to go online for some fine tunning as we need to run between 3.9 to 3.8bar's.
Aparently the remap is not needed as the OEM ECU has a very good adaptivity up to 25% of the factory set's and we are trying now to foull it's limmits and tolerenceses.
Over all i am very happy with the outcome but i want to see the reall figures.
The car is now back to my garage and i finnaly manage to find some time to work on the air box. I used a clean sheet of alluminium 2mm thick and after some cutting and bending here are the first photos.
I did a bit of cutting on the slam pannel to clear the path of the air and the bonnet fits just fine on top off it. The airbox will be supported on the engine block so movement want cause any issues. Also the sheet goes all the way above the radiators so hot air is out of harms way. Now the only thing left is to finish the base plate for the bodies weld it on the airbox and collect the trumpets to go with it (many many thank's to Mr Rich_W)
Matterials for the airbox:
Hopefully by the middle of this week i will say that this project is finnished, give you the official numbers and move on to the Kit-car body preperation.
I hope you like it.
