Comptech Race Header vs Toda Competition Header
Comptech Race Header vs Toda Competition Header
Any comments on those two headers? which one is better?
Better ground clearance or performance/torque gains?
Thanks!

Re: Comptech Race Header vs Toda Competition Header (bcrl)
Comptech race is a copy of the original ITR HyTech header. Makes great midrange and topend. The TODA is a good unit as well, but with roughly the same cost as the Comptech, and not as much power potential, the Comptech Race is definately the choice between the two.

Re: Comptech Race Header vs Toda Competition Header (bcrl)
.....actually, I've done some testing and on a bolt-on itr with cams the toda header had more midrange and the same top end as the comptech race design.
So get toda. The ground clearance is MUCH better.

Re: Comptech Race Header vs Toda Competition Header (rowdy type R)
IT ALL boils down to your plans for the car. On a lightly modified R the Toda will be better suited. But on a higher displacement or higher output R, the Comptech has room for more capacity.

Re: Comptech Race Header vs Toda Competition Header (SuperTwinz)
If you look at the graph the Comptech Race header only makes peak power. The Toda header makes more power throughout the whole power band. Seems like the Toda header has more useful powerband.

exactly....you need to think of the whole engine instead of a bunch of pieces that "make mad power yo"

The testing I did had virtually identical delta's.
I remember thinking that over 9k rpm/ with higher than 11:1 cr/ >1.9L would achieve better results with the comptech style.....

Flow logic would probably tell you that based on the longer tube design and less drastic bends. But then again I'm not a flow engineer so I might be totally wrong.
