That's a lot of Schedule 40...

I know people get a kick out of Magazine articles, but just for conversation sake, in the latest issue of Car Craft there is a fellow that has a LS2 bored and stroked to 441cu-in (4.125 x 4.125), along with being converted to a 6-bolt head bolt arrangement by ERL. It supposedly has box stock Trick Flow 245 heads, running a huge Precision 106mm single turbo on stock 6.0L truck manifolds pushing 32psi of boost, generating 2000hp and running 7.50’s at 194mph in a ’00 Firebird.

I know the little hondas benefit biiiig time by running these ramhorn and equal length style manifolds..some gain 50-100 horses with the same boost level but I guess with these big V8s we have enough exhaust volume that manifold design isn't as critical. Looks badass though!

I wonder how well a set of the LS Marine style exhaust manifolds would lend themselves to building a twin turbo set-up, besides being expensive. The may position the turbo’s too far back being centered, but they look as if they should be heavy enough to hold up forever.
