Love seeing these comparisons, would like to see more similar tests in the future!

[@trevoronkalo6123]

Honestly love these videos , learning and seeing the differences is just fascinating. I personally wouldn’t complain if we saw more videos like this and wouldnt complain if the videos were longer.

[@mattwood9981]

Very cool, great side by side of the possible changes!! Keep killing it guys!!

[@jamescjhealy]

I'm stoked you did this video.

[@NickBeek]

I definitely like when you do comparisons like this with the dyne doing the measuring. Great content!!

[@jonesboyshunting8673]

Awesome job guys. Always learning something new. Keep up the great work

[@foxxx5.941]

I agree with the other comment I like seeing these dyno pulls b4 and after added parts. Keep up the great content. N thanks for taking care of me on the trans reducer n Gov solenoid. Sorry it took so long to ship old ones back

I would really be interested in seeing the comparison of a factory exhaust manifold vs a Steed Speed exhaust manifold to see exactly where and how much it is picking up power in the curve

[@mikestrucks]

Awsome video ! What a difference with the new head 💪🏻

[@rossbrowning2669]

This is one of the best videos I've seen yet from you guys. Would love to see just how clean burning these high power rigs can be. In the future could you add a small PIP of the exhaust outside during the pull?

[@bandabanderos]

That’s a solid safe combination right there 👍

[@bagged1998]

Ready for the lesson

[@bandabanderos]

Would be nice to see the low end graph comparison too. Max peak hp vs overall gains under the curve

[@HappyGunmore]

Like a little kid when he saw those numbers. Nice job guys.

5 blades make beautiful noises 🤤🤤

[@mastafaforga]

How much did it change the spoolup? Did it just make more peak power or did the power come in a much sooner?

[@slow_sylvs9643]

Damn good numbers! Does it also have a cam?

[@sicsempertyrannis8830]

Wich one of your employees are screaming in the background

[@BentonL]

150hp diff with some flow manipulation. Least now I know I am not wasting my time with a burr tool.

[@V8Lenny]

Must have been lots of unburned fuel with stock head and intake ?
