Banks style, non-intercooled, restrictive air filters........I'm guessing 350 hp at the crank tops. Unless there are some internal engine mods that they don't have listed here.

For 50k invested I hope they redid the engine.

Its kind of like doing a christmas grab bag, you never know what you're going to get. Could be a 350, could be a stroked 400 block.......

Without seeing compressor maps of the turbos how could you even begin to guess?

Assuming the turbos are sized correctly then it has nothing to do with the compressor maps. Its all about the engine. If they are running a crossfire engine, stock 235hp or so, and add boost to that. You can figure a max of 8psi or so non-intercooled. Which is a 50-60% power gain. So you are looking at 350-375hp ideally. So a guess of 350hp would be about where it would end up without the intercooler.

Now if they have done some engine work, all of this goes out the window. Like I said, it might be a 427ci engine with some wicked heads and those turbos might be undersized for it. It could be in the 6-800hp if that's the case.

But I also don't think those air filters will flow 300hp a piece. They might though. It would be interesting to see if there are any hp gains by pulling the air filters.

What a strange car. It must have been built in the late 80's or early nineties.

Looks good from the outside, and with some finishing touches could be a really sweet car. Hell, it might already be a really sweet car.

Hrmm. I guess I see your point assuming it was a stock crossfire engine.. Can't tell from the pix.

Other than the color scheme, the gauges are a nice fit.
