Did the VRX badged Magna's have headers similar to the Ralliart, different headers again or headers like that on the Exec's etc?

Just curious. And, I was wondering were the extra 13kw came from.

All the headers the same except for the ralliart which had hm extractors. The extra 8kw from the exc to the sports/vrx was just the rear box changed

I did read a little while ago that the vrx had a different tune?? Could explain the extra KW.

What series are you comparing to skraper?

Redbook has the Series 2 TJ's as; VRX = 163kw, compared to 155kw... but I was comparing it to the quoted spec's of a series 1 TJ exec (150kw).

......extra 8kw from the exc to the sports/vrx was just the rear box changed

Suggest you do more research on the info available on these forums. Not totally correct.

Here is an external link (http://autospeed.com/cms/title_Mitsubishi-Magna-VRX/A_109590/article.html) for you to read. :)

And one more, that goes into the ECU mapping and stuff: link 2 (http://autospeed.com/cms/A_1437/printArticle.html)

Both interesting links - thanks.

It was just a general question. Is there a sticky where I can go that lists (in detail) the differences between each model? Maybe we need one if there isn't.

If I were to install the HM ralliart headers to my VR-X would this make the exhaust note that much louder?? I would be keen on a few more Kw but I like the note the VR-X already has. Does anyone know what is today's equivalent to the ralliart HM headers and where to get them from??

Those who've actually looked at the maps in the different ECUs have found that, excepting the Ralliarts, the fuel and ignition maps for the 3.5s haven't changed since the TH. Other maps may have been tweaked which could improve behaviour slightly, but the fundamental tune wasn't changed.

Seems to me that "revised ECU mapping" is often car company speak for "we claim to have found a bit more but we don't want to tell you how we did it"...

I'd believe that.

Were any of the claimed figures for output ever tested?

Execs went from 150 to 155 with a cam change, vrx added a free flowing muffler

Okay. Off on a bit of a tangent now, and possibly over old ground. Has anybody ever demonstrated the "8kw from a free flowing muffler" (+5%) theory?

Just FYI, I only started this thread as I was looking at buying a VRX and wanted to know if my current exhaust system (HM Headers, Lukey rear etc) would bolt straight up. Right now we're just shooting the breeze.

Sure will bolt up, all the mounts are the same.

Here's what I've come up with using ham fisted grade three mathematics and the third gen dyno results.

The best comparison I could find was the two 2000 auto Veradas, one stock and one with exhaust mods - hopefully equating to "high flow rear muffler" - Increase in power of roughly 14kw. Divide by two for the reality cheque and you get 7kw possible increase from a high flow rear muffler alone.

Sound fair? Makes the VRX claim in question seem legit.

Of the two standard 2002 VRX's the average KW at the wheels is 124kw. Assuming both originally produced the 163kw at the crank the drive train loss is only 24%. Call it 25%, its still pretty good. There was a VRX manual listed with both a panel filter and HF rear muffler, pulling 135kwatw. But without knowing a good drive train loss figure its hard to determine the actual KW gain from those two common mods.

Only can compare if all cars were dynod on the same dyno on the same day, otherwise test is completely invalid.

Edit: Evidence, my car is 149kwatw at pulse and i think about 144 at port hacking automotive.
