Racing Beat PCM flash - PORTED engine
Suprised nobody has posted this.
Racing beat has a Version 3 PCM reflash for ported engines. On an engine dyno made around 248 HP and 165 TQ. Link to dyno graph. http://www.racingbeat.com/FRmazda4.htm On top of porting they revised the Intake actuators and Intake Dynamic Effect Valve. On the most powerful pull they basically through every RB part they had at it. Intake, race exhaust, midpipe (cat delete), header, etc. Rev limiter raised to 9500. Wonder if they now offer a porting service. Very cool anyhow. Nice to see such a nice dyno over stock (which is listed as well.) |
They offer porting templates
|
^^^
Just saw that, didnt scroll down far enough on the site. |
I was just about to ask what they'd done porting wise :)
Looks more like a tidy up job than anything major? |
/\ if they have templates there must be a few shape changes as well
|
Good find. Especially that porting template. Definitely something to add the list when it's rebuild time.
I'd be interested to see a review from Easy on what rb has done relative to what he does. |
That sounds like a pretty nice bump. Honestly though I would have expected more than 20hp from ALL that. I bet its crazy expensive too.
|
Before you get too excited you might want to research it further to make Sure you understand everything fully .....
. |
Pics of the porting templates have been floating around here since SS. Cool to see RB still doing R&D on the Renesis!

248HP 165TQ engine dyno Iam not excited
Maybe Iam wrong but how much RWHP it will be ??? Around 210WHP?? It can be done with MM AP and you dont have to do porting which will not be cheap |

If I will do rebuild I would like to have this done but alone just for it no thank you :)
And they dynoed it without cat and with their header I wish the numbers could be a little bigger225 maybe ? But few years ago we have like 240-250WHP with greddy so I think its still a good thing for rx8s |
They mention that there was cleanup porting on the stock plastic intake manifolds as well. I need to investigate this I see, as I am having my build ported.
|
this sounds perfect for what i have in mind for my car. i guess i should check in with RB more often.

Which means we are finally back to where Mazda said we were supposed to be when the RX8 first came out. :(
|
Which a number of people have already exceeded without it ;)
|
Agreed. I picked up on that too. I'm not sure I can see what the porting itslef does in their example.
|
It changes the area under the curve.
|
IMO porting will provide that last bit left internally when allowed (racing class) or wanted (street etc.). However, I'd have it performed by one of a very few select engine builders, which will only be provided with an engine build rather than a stand-alone modification.
|
i havent read the site---do they doing anything with the exhaust ports?
OD |
exactly what teamrx8 said^

Yes
|
if they could take the jet air nozzles out of the lim they would gain a little bit more
the lower intake can stand some clean up also Nice little bump get the rotor clearancing at the same time and the modified oil bypass to up the pressures as they did? i dont like the 9.5 k redline for a street car. OD |
