DynoJet testing of ZZ4-MiniRAM w/ LT4 HOT cam
To compare the advertised benefit of the MiniRam TPI intake, I was lucky
enough to borrow one from Tim Siford (Thanks Tim!) and tested it on the same dyno, with no other modifications
to my motor or car. My default intake is a heavily ported Edelbrock
TPI base, large-tube AS&M runners, ported plenum, and 58mm Edelbrock
throttle-body. The graphs and data are below:

Hi-Flow TPI Tests
The Graph below shows two of the MiniRam runs plotted directly against
the last Hi-Flow dyno run
The corrected numbers pulled from the above graph are listed below:

Diacom scans from the 4 runs show knock/retard at 3200rpms which I
traced to a large jump in the ARAP PE spk-adv table I had copied over
to my MAP chip base. I have since remove it.
