8 Attachment(s)
Since Rx8 debut, old Rotary community all have
What if ? 13B MSP have PP exhaust!!! Now after a few years of planning &developing This is sec prototype my friend build for Rx8 First one is Turbo version~ This one is NA Build Update 10/26 2022 at page 16 Here is Dyno sheet using Dynapack Solid line is 13B MSP Ext PP Dot line is stock 13B MSP |
Awesome ! Been hoping someone would do this for a long time. Very keen to see how it all pans out.
The big question : what have you used to seal the side exhaust ports ? Looks like JB weld or similar ..... :eek: Also , exhaust header has no turbo flange ? |

Can't wait to see Team's reaction to this when he emerges again. I miss/don't miss his input. You know what I mean?

I would love to see more about this. I like to see people actually build things.
|
I was following the turbo one on youtube, I know you lost compression on the one rotor, what was the result? And whats so different about this material than last?
|
my reaction is simply to wait and see; my position has always been that the cost and effort won’t justify the input of resources and hassle required for reasons illustrated and discussed in detail in various other threads on the subject
**until someone demonstrates otherwise**. Been waiting patiently for 10+ years and still am … kilawatts, with all sincerity; I’m sad for you. :( . |
Ready to go
|
Bump for interest. I have some s4 housings but the coolant seal issue

just listen to the difference here on the downshifts: It’s easy to see why though. Once you change from a non-overlap intake-exhaust cycle scenario then all the rules change too. Nobody is picking up on one of the most basic ones that’s right in front of their face. No surprise at all, really. . Car is not full tune yet , just start up ready to brake in Is not fair to compare to this stage |
ok, fair enough that it wasn’t clear about the status.
. |
Even with stock Tune , engine feel Lots TQ
And pull to redline smoothly |
Interesting!
I thought this project was dead in the water. Any thoughts on going to a dyno? |

thanks for recharging my “calling bs” balloon :suspect: it’s not like I never heard anyone claim this before and then dyno 180 whp.
. |
a month later :dunno:
. |
To be fair in this current environment 1 month is not very long. Most good dyno’s around me which are many are all tied up for the next 2-3 months.
So no surprise. Looks a bit slow Erving compared to stock but not saying that can’t be cleaned up with tuning. Cool build for sure. |
true enough here, but this effort is in Taiwan
it was long enough to break it in … just going to leave it that though. . |
I would love to see it on the dyno.
|
hopefully we can finally put this lie to bed soon enough for what it is:
not surprised at all though . |
There is no lie, just people trying stuff that may or may not bring good results.
