I am always happy to see a supercharging project underway. That's a nice looking Lysholm unit. I guess you are making a special hood, it should look really mean. It will sound mean too!

Which Getrag is that? looks like a BMW unit.

Should be a nice ride when it's finished! :twisted:

Is this going to be intercooled? What size is that supercharger, how much compression and boost are you planning on?

An interesting bit of engineering development to be sure and not to take anything away from the project, I am left with asking the obvious question. How far can you blur the lines of a make and say it is an Alfa Romeo? At the end of the day, this should be a successful unit based on what I have seen, but in truth, it could be a Ford Cosworth with a carved up Alfa shell, it could be any make you like as it is just using whatever performance parts are suitable to make the whole. A good car in the end but an orphan just the same.

If you fit a turbo charged Rotary into your GTV6 shell which you can, are you still going to call it an Alfa or should you call it a Mazda? Personally, no. I would automatically call it an orphan.

I think the greater challenge is to use Alfa parts alone or parts used by the factory itself and work them to their limits. This may be more limiting but a better reflection of what potential the make actually can deliver.

The only non-Alfa parts is the supercharger? I'd definetly call it an Alfa.

Orphan definetly is more diplomatic then "bastard", nice touch. :)

I guess the gearbox in non-Alfa.
However, I couldn't care less. If making a good car requires some foreign parts I'm all for it.

Oh, I read too fast, thought it was from a Sei.

Anyway, as long as it has an Alfa engine...

MD the reason for front mounted gearbox is the transaxle wont handle the 500 + HP, obviously you are nowhere near the limits of BIG HP, Alfa dont make a gearbox that will do the job short of purchasing a $30,000 hewland transaxle, as for your other comments about not being an Alfa is pure Alfa, the only non Alfa part being gearbox. Even Autodelta/Alfa Corse used Hewland internals in their Supertourer gearboxes, this is a "sports sedan" but still retains monocoque construction. do you race with VRA? they wont allow the fast cars to run afraid of being beaten!

That's an impressive supercharger setup. Obviously it's not going to fit under a stock hood, but it will probably fit under one of the Group 4 turbodelta type hoods.
