NICE!!! Magnuson quotes only 76-HP. Even though you're not running their tune, it's still nice to see those kinds of gains. Not a lot of people run this kind of combination, so for people who are interested in what just the blower (and a few airflow mods') do, this is very helpful. As you likely already know - heatsoak has a BIG effect on power, so if you came right off the street, and onto the dyno', the ECM's probably already pulling timing right off the bat. Compound that with multiple runs, and you'll be pulling 30-HP before you know it. Or - none of that happened, lol...
After reading about that stupid check valve, now I'm pondering that... Christ... I don't see problems, but why wait? And that dang Toohighpsi-port system looks SO TEMPTING...
Regarding your baseline - what gear was it dyno'd in? If it wasn't in ?5th? (is that 1:1 on the 8L'), and run in 4th, for example, it'd show a 20-RWHP (or so) less. Some guys don't like running their dyno's at the higher speeds these 8/10-speeds are in 1:1; 10L' is like 7th gear, and tops-out somewhere around 170 or something. If you weren't running in 1:1, that could account for the lower baseline. RPM just posted a video of Fran's V3, stock, and it put down not much more power than yours, so your numbers don't seem too crazy, from what I've noticed. I recall seeing numbers similar to what you'd seen, too, so as long as the dyno' was run in the same configuration as the baseline, who cares? Gains are gains
Thanks for sharing!!!
