according to the sc we have v8 pow3rz!

 

are you still using that AP with the Cobb map?

 

yes i am. my rx8 is not heavily modded power wise.

aem intake.
turboxs headerback.
cobb ap stage 1 map.

the weird thing is, i feel like i have 2 dips in power. its not linear. i know one is right around 6500rpm. i believe thats the secondary intakes opening, right? its pretty damn noticeable though.

 

Could be the VFAD for one of those dips?

Check Kane's MAF scaling thread, there's a procedure for load MAF scaling.

 

vfad? check my first mod.

 

Hah. I'll claim illiteracy thank you very much.

I only know of one dip, and that's the VFAD for me. Can't imagine any other reasons for dips...

However, I remember seeing an old RX-8 dyno where there were two dips (at around 3000 and 6000 rpms). I'll try to find that graph .

 

kersh4w.. the Cobb map is not supposed to be used with an aftermarket intake for that very reason.

your maf needs to be scaled.

 

372 was my highest so far.

 

ahhh. that makes sense. i thought they use the same diameter piping though?
