Prodigy Performance 3.6 Turbo DIY Install

CMR had better include authority over cam phasing!!! If not, then what are we doing? Playing with AFR and spark timing?

And you've got four independently phased cams each with their own electronic actuator/sensor. According to Borg Warner the advanced VVT system is responsive to load in addition to RPM which sounds like torque management to me. Whatever it is it can most likely be optomized for a turbo. Most VVT systems phase intake and leave exhaust alone but not Pentastar. Huh. . . wonder if they included exhaust cam phasing in anticipation of someday bi-turboing the RAM 1500 or some other similar application. Ugh. . . It kills me that all of the raw materials are there but you have to have the software - ALL of the software - so you can make it work and the darn OEM won't release the code. And from my conversations with Magnuson, DiabloSport can be difficult at times. In fact, in one conversation a person at Mag who does not want to be on the record went on a five minute all-out rant regarding DiabloSport. In among the explitives were some salient facts such as the fact that DiabloSport actually generates the calibrations which goes beyond "support" to actual partnership. Also of interest was the fact that Mag pays thousands and thousands of dollars for the calibration engineers that DS provides. Of editorial color was the statement, "we are slaves to these guys. . . " I'll leave the rest out.

Speaking of cam phasing... I found a decent intro explanation of how cam phasing affects both NA and turbo engines: http://www.hamotorsports.com/cam-gear-tuning.html

With full control over the VVT system, it could be optimized throughout the RPM range. I'll try to get some details about how much control CMR has over the VVT.

Yeah, the exact nature of the relationships between the turbo/supercharger manufacturers and Diablosport is a bit of a mystery to me still. I know it's definitely more than a basic customer support relationship with regards to the CMR software. That's one reason I'm patiently waiting for Prodigy to improve their tune rather than running out to a local tuning shop. Prodigy is going to continue to work closely with Diablosport to improve their tune and to address issues reported by many customers around the world, and the resulting improved tune will be made available to all Prodigy owners. For free!

A local tuning shop will only work on my tune for the couple hours that I paid for. I'm sure they'll gladly allow me to pay for more tuning time if I come back and report some mild driveability issues, but they won't have the benefit of feedback/logs from many people around the world, and they sure don't have any motivation to continue tweaking, testing and improving the tune once I've handed them my money and drive away. And they won't have as strong of a partnership with Diablosport as Prodigy, RIPP, etc., to be a driving force to improve the CMR capabilities for the application.

Kinda off-topic, but not worth it's own thread...

I got bored and took pixel-perfect measurements at every 100 rpm increment from Magnuson's own dyno chart to add their boost curve to my collection:




I don't know why that chart stops at 6100 rpm. looks like the torque curve is leveling out, so it probably doesn't go up any more, if at all, as it approaches 6500 rpm.

I'd like to add Sprintex to the chart, but I can't fund any charts with a boost curve. Has anyone seen anything?

This chart really belongs in a thread about comparing all major power modifications in general. Seems like it would be good to have a continuously updated post that lists all the options, gives basic info about each, provides links to more info about each, etc.

What do you say to letting me take the post and start a new thread. I only hesitate because you specifically state "not worth its own thread".

If anyone could chart it out pickles, its you. What do you say? Everyone loooooves to O.D. on charts and graphs.

Maybe this is a dumb question, but if RIPP and Mag indicate they are producing 8 PSI of boost with std pulley, and 11 PSI of boost with High Elevation pulley, why does your chart (or their data) only show Magnuson with a max of 6 PSI?

It's over. Stop. Please.

Why Pickles... What did the Ideal Gas law leave you cold this morning? Or have you finally realized that, yes, you need more data to make any intelligible analysis of the Ripp v. Prodigy systems?

This thread is off the rails. Spiraling out of control. The tech discussion here makes my head spin.

I do need to correct myself on one detail, though. The reference for "volumetric efficiency" is atmosphere, rather than the intake manifold, as I incorrectly stated early. This does not invalidate any of the concepts or relationships I described, though. So volumetric efficiency is the percentage of a cylinder's volume worth of ambient atmosphere air (the amount of air, number of molecules, in that volume of atmosphere) that actually gets into the cylinder. Boost causes a volumetric efficiency of over 100%.

What happens when we increase our volumetric efficiency from say 80% to 90%??? I'll give you a clue--- AIR DENSITY INCREASES!
