Thanks for the pics..

And yeah the pics of the joins to the flange would be great

 

Hey Ronny, I am wondering if there might be a different way of figuring out the runner lengths, because the Guru racing bridged IPRA motors have way different manifolds. I have to say that your manifold looks awsome. How did you mate teh piping to the odd shaped primary ports?

 

Man I nearly crack a fat every time I see that engine..



My guess is that the guru racing, as with most IPRA cars, run insane RPMS, 13-14krpm in qualifying stints, for that high of an RPM you'd need a short runner, even if you have a very agressivly timed brideport!



Thats just my theory, I stand to be corected.

 

They could be also using a smaller R value. the only suggestion i have is to join the two secondary tracts with a nice gradual curve of pipe to take advantage of vdi better.

 

Here's a drawing of the intake I was thinking about. I plan on keeping the 5th/6th port actuators in place, that's why I need two separate runners for the front a rear plates.

I haven't figured out how to get to the actuators through the runner, and I haven't shown the injector locations.

Drawing is not to scale, so ignore that the runners appear to be different diameters... MSpaint ain't no CAD tool.

 

Hey dude any chance of them pics?

 

did you keep the 5th and 6th port open all the way? im currently working on a custom n/a intake to. where did you get the flange from? thanks
