Stock Fuel Injectors swapped

Pulled the stock fuel injectors from the intake manifold that has been in my S4 and put them on the Silly Rabbit Motorsport modified intake manifold which is going to be using the Integrated Engineering fuel rails.

Also, sitting on top of the intake manifold is a fuel pressure sender inline with the hose adapter I got from Paragon Performance, this will be sending data to the Podi dual display gauge as well as to the Innovate data logger.

I am also still piecing together the vacuum hoses trying to decide how best to route them and where the components should be placed.

Possible Frankenturbo Future Offering

My turbocharger candidate list is still open while I try and find an upgrade that fits what I am looking for.  A potential contender is a revised FrankenTurbo F21 that Frankenturbo released some early prototype photos of.

A revised, billet, compressor wheel:

and even more interesting, a mixed flow turbine:

This looks to be an excellent combination for trying to maximize power on a stock motor while retaining good spool up characteristics.

Time will tell if the prototype lives up to the design goals.
