Front mount header hp potential

[rx1 fern]

What is the limit Hp of a front mount 4 to 1 header . Say you change the header flange and weld another one on and install a gt 3076 . Will the front mount be too restrictive of a header for good flow . Thanks.

Sort of a tough formula to calculate with lots of variables. In general I would say yes it would limit a little power compared to a purposely built one for the turbo, planned usage, etc. I would want a impulse race mid mount header for a turbo that size just for spool.

Gonna build one I think . Bought a merge collector to build one with also. Bought a precision 5558 turbo also for sled .

Some of the progress so far . Lots of work fabricating new header . Now I know why headers aren’t cheap to buy lol . Should flow nice this setup .
