Russ, I really wanted to go with that exact performer x mani but for the price of the BLOX, it just wasnt worth it. Now, if you try it and it yields better gains, then ill get one.

 

Because you enjoy hemorrhaging money.

Well I still want to see what kind of gains on a blox VS stock. If it's a large gain then I'll get the cheaper one. If it's just a bit I'd rather give the performer X a try.

 

qft

 

Blox is a Skunk2 knock off.

The Performer X is generally considered "better" for at least naturally aspirated applications. How much better on a boosted Miata? I'd wager it has more to do with the fab skills of whoever puts it together than the manifold itself at that point.

 

That is because the ports are much smaller. IIRC this is a D-series Performer X on top of a factory B16 intake manifold:

 

Forget about the port sizes on the Honda mani's. They're all larger than on the Miata heads.

I know, I was just pointing out the reason why b-series manifolds show better flow numbers than d-series.

 

Found something really cool to contribute.

Cheapness. Also, no one has got this working on their car yet. Damn all of you.

 

Nobody's gotten what working? A Honda IM?

 

I have seen no dyno chart

 

leatherface JUST posted his. Savington has posted his.

you are failboat.

 

my torque curve is the ****. I have to go turn up the boost a psi or two

 

i wish u could have posted ur datalog of ur map on that dyno run

 

next time

 

mmm... I'm looking forward to installing Lev's manifold.

 

I assume you tuned for the manifold? If so, do you know why it so much more fuel below 4.5k RPM? Interesting.

 

Oh looking what I found for sale on here...

probably because he was too lean and wasnt making much power because of it.

you can see in those areas where it is richer the power is much smoother now... probably the difference between a street tune and a dyno tune.

 

the fail is strong with this one
