TF & Speedmaster Flow Tests
I’m surprised that by now there have been no reported dyno shoot-outs between the TF’s and some of the other offerings.
Like when EM did the test between stock/stealth/Ede/TF240’s.
You could do stock, SM, Ede, TF190.
Only, instead of using a basically stock short block, use something like a 10-10.5:1 stroker with a decent sized cam in it, and an intake/carb that would keep up.
Fundamentally I’m a fan of the TF190, but I’ve never used them on anything myself.
I don’t look at them as an alternative to an offset rocker race oriented head.
If they made 575hp, straight ootb, on a pretty basic(although somewhat rowdy) combo……I’d say they are doing what I’d expect out of them.
Certainly, that level of performance is achievable out of reworked Ede/SM heads, but that route requires more effort from the end user than selecting “add to cart” from summit’s site.
