Mods are gasket matched heads, larger cam, poorly done gasket match intakes, DM ported upper to 56mm, Stock 52mm throttle body, Fiero Store Sprint Manifolds, open dump after Y pipe. So really not all that much.
The reason why I have the 52 mm tb on there is because the 56 was sticking at part throttle and was a pain in the ass at slow speeds. So maybe there is a bit more left.
Its def stronger then my old engine. You can see it fall on its face after 4500 rpm and I am hoping that maybe the dual tb intake can correct that. I would like to see what it can do as its obvious the motor dies hard. Not sure when or if I ever get around to dynoing the dual tb though but if I do I will be sure to post the results.
This is a comparo of the old engine with the dual tb vs the new.
This was just 3 runs on the dyno with no tuning. I didnt' play with my safc settings at all.
