these are my first dyno runs post Radix install (ok, so maybe they are a little over-do)

had a fantastic day working with oxidizr on the MP112 baseline test/tune. Understand when I refer to "we" the emphasis is heavily favoring the tuner and not myself.

The goal was to optimize the current calibration/setup, taking a stock Radix with basic bolt-ons as far as we could while staying safe for daily driving. Some interesting things of note, 1st, while we did the bulk of our testing with the converter locked. We saw no power gained from testing unlocked, the power curves essentally lay on top of each other. 2nd, due to the 2500HD converter being considerably looser than a typical 1500 series, we weren't able to lug the motor as low as I had originally thought we might, however it was consistent at its lockup point. 3rd, 7lbs of boost. 4th, all data corrected to the latest SAE standard. 5th, fuel pressure was 63psi at idle and 63psi WOT/6000rpms 3rd gear(in tank Walbro). 6th, all runs conducted with hood closed.

Max power gains over the stock magnacharger calibration are: +8rwhp, +9rwtq. However, the real benefit observed is with the power under the curve. You can see on the dyno graph the sections in the power curves that are +15-20rwhp +15-20rwtq. The net result is more usable power, sooner.

I am very pleased with the final baseline results that repeatedly showed 430rwhp/440rwtq. Figuring 18% driveline loss, roughly 505hp/520tq at the engine. Just after I bought the truck in late 04 I had it dyno'd bone stock and made 245rwhp, so for a stock LQ4 Radix setup(3.1" pulley) with basic bolt-ons (LT's, dual exhaust, CAI), and a custom tune, I'm pretty happy with the results so far as I'm up approx 185rwhp.











MP122H data to follow

Looks bitchin.

Can we see the rest of the dyno graph, or did you start the pull at 3750rpm?

thanks , this is the only dyno sheet I have, runs started a little bit below 3750 rpm.

nice work. With all these performance goodies out there, it's just a win -win situation for us truck guys.

thanks bro, I think we're at a good starting point, we were able to collect the data needed to move on to the next project




sorry no video, I had my camcorder sitting on the kitchen counter but left the damn thing sitting there

Good Job, Richard knows his tuning.

these are some good numbers to see amd congrats. i am hoping to be making a magna purchase soon.

Grippy, if you dont mind me askin, what do you have planned next now that youve seen what the charger will do?

Thanks diehard

testing was done with the expectation of upgrading to the new MP122HH blower from Magnuson. We thought it best to baseline my current setup to its maximum safe potential, then do the blower swap, tune the new setup to its max safe potential, and compare/share the results.
