looks cool, but how does the dyno feel about it?

 

Excellent spoolup and torque curve. Hint look at Gary Gardella's car

 

Hey... it's the same as the thread in the FI forum

 

can someone enlighten the less informed as to what benefit these antireversion chambers provide?

perhaps that will make this thread technical rather than just a bunch of pretty pictures.

 

Laminent flow collectors flow great. Unfortunately they flow great in both directions. The idea behind the bulkhead in this collector design is to reduce the amount of flow between runners. As a result you get quicker spool ups and cylinder scavange. If it didn't work Gary wouldn't be winning. GM did some homework

 

What does the inside of the collector look like, anything special?

I'm not seeing how reversion is going to be a problem, most modern day engines do not even experience reversion in the first place and i'm not seeing how this would benefit spool up time? Do you have any back to back dyno charts? anything showing the difference in curves or spool time?

The reason i ask on a header we design for a PRO RWD 2JZ engine we did not experience any reversion issues and we gained a significant amount of horsepower from running a tuned length properly sized header in 6-2-1 configuration. not trying to be an *** just trying to start a good discussion on design theory's

Haha, i don't think it's that simple. Gary's car does not win because of that manifold design.

 

race wins aren't based on manifold design....and purdyness?!

back to the drawing board

 

wow awsome work.
