Hi Hemi,
Yes I am aware of runner length and diameter tuning, but as mentioned above due to packaging there isn't anything I can do to that.
To simplify it, basically I just want to know if enlarging the plenum sizes alone will have a positive benefit. I am OK with slower throttle response...
I have an engine that I've done the following on-
airbox
ecu
cams
ported head
headers
high flow cats
exhaust
This has brought the HP/TQ at the wheels from 201/198 stock with a redline of 6500 to 249/232 currently at a redline of 7300.
There are no other commercial parts available to get...
