Car is a 16 GT, manual 3.31 gears. Car pulled 427whp 378tq with the gt350 manifold and 420whp 389tq with the stock manifold. Didn't think the tq loss would be that much, but knew it would take a hit. I'm pretty disappointed in the whp though, really only a 7 hp gain? All pulls were done on the same dynojet dyno, both on e85 flex tune, just one with the gt350 manifold the other with the stock manifold. Yes the curve gains are where it really counts, but still. Stock manifold was falling off at around 6700rpm, gt350 kept pulling up to 7700rpm. Is it just me or does this seem kind of low for numbers on e85? I'm seeing the majority of dyno's in the 430whp+ range on pump gas and same mods. was about 84 degrees out today. What do you guys think?
