It would be more sensible to compare it to the GTX though, as they are both billet and can both run high boost efficiently. As said though, there are no direct comparisons or even decent GTX3076 results on built engines. Shame mine isn't a manual, although stock manifolds and cams will be restricting my output severely anyway.
Too many variables unfortunately, but the HTA definitely spools nicely. Lithium, can you buy the HTA 3071 chra separately by chance, and will it drop in to standard GT3071 housings?
