Ultima GTR 434ci (7.1L) Engine - Throttle response testing

Video of my Ultima engine on the dyno. Here we are setting up the fueling for the throttle response. The flames out of the top are due to a weak mixture which was correted. Engine looks like it's trying to escape from the dyno machine!! :-)

Yep. The headers are 2". Standard Ultima are 1 3/4" and are very restrictive for bigger engines. They sound awsome!

Flames were due to a weak mixture (which we were correcting during the test). Bloody scary!

@LoZioFBV far as I know a big block don't fit in a GTR this in a small block you can stroke and bore an ls7(smallblock) into 454ci.

A 2 barrel firing back at you is scary, dual quads must be terrifying.
