When quadruple overkill is still not enough. :eek :thumbsup


Oh yeah, quadruple is the same as redouble in Bush the elder's language. Now commonplace.

Wow, that thing is going to be a monster. Tires sticking on the road is highly unlikely :)

I diven a continuation cobra with a 427, and that was scary in it self. Can only imagine what this beast will be like....

I am curious to see how well that setup does without overheating. I had a CSX4000 and even with a bigger radiator and a third fan (in comparison to original CSX3000s), it would overheat if not going over 20 mph. Your setup looks awesome and will cram even more gear under the hood, hence the question about how well it does when going "slow."

Well, those 427 are seriously underpowered and way too slow...so they really needed a TT. NOT. LOL

I'd like to see the plumbing that gets the exhaust forward to the turbos and still gets it out the normal sidepipe ports.

More pics please...
