FWIW I have a fuckin gutted 01+ plenum in my GF's dad's trailer. Who wants me to do a back to back test! Yay! Fuck, I will do a whole intake manifold shootout on my own dime if you bitches send me them to test.

Hmm starting new thread

Does it looks like your frame rail?

lulz

My frame rail fucked your dad for breakfast. I can post hot pics of intake if you want.

rule 34 on your frame rail?

Some pics of my modified 94 manifold.

Interesting...def. loks like something I'd like to try. How much did the EGR equipment impede into the plenum? Looks like a much better flow over the NB IM.

I don’t think the EGR created much impedance to flow but it had to create some. It had a little hump right after the throttle body to create a disturbance for better mixing of the EGR gas. I was sort of conscerned the little hump might actually improve flow by creating a swirl but I decided to take it out anyway. My car started out as a 90 so it didn’t have EGR originally.

I suspect my manifold performs similar to some of the Honda setups, but with slightly longer runners. Seems like to me the short runners would be more tuned to RPM’s beyond where a Miata motor happily runs.

This is the intake mani I wanna use badly

"The "Performer X" series of intake manifolds from Edelbrock are an ideal choice for high performance street or strip applications that have peak torque and horsepower bands in the 4500-8200 rpm range."

Interesting that my torque hump is more 3800 to 6000 rpm. Start loosing torque pretty rapidly at 7200. This is with a 2.0L stoker with all the Flyin Miata bells and wistles and a 99 head.

I don’t think it is the intake manifold that is the primary source for the torqe drop at high RPM though.

Because you are fail and don't listen to people who are win.

What do you think is the primary source?

probably cams Im guessing.

Bob, what you did with that intake is great.

I have had this question in my mind for a while.

Those pics def mad me feel like that IM is much better than my current 99gutted set up.

I may look into that after the Vegas event in a few weeks.

I am also interested in the new BEGI intake..

And a head that is generally poor flowing when the cams are open.

Yea I think it is a combo of the two.

The strong point of the Mazda BP engine compared to a Honda is mid range torque It is simply different than a 9000 rpm Honda. Putting a 9000 rpm Honda intake manifold on a Mazda head doesn’t suddenly make it flow like a Honda.
