For all you guys who've dyno'd your X MR, did you guys do runs in the different SST modes? This article says that boost gets higher based upon which SST mode you're in. Is this true or BS?

"When each of these modes were tested, each yielded a different boost peak. Not only do the revs sit higher the further up the mode you go and the shifting become quicker, if not violent in the “super Sports” mode, but the ECU once again communicates to the SS-T and vice versa, so in “Normal” mode the boost peak was 1.3 bar, “Sports” peaked at 1.5 bar and “Super Sports” peaked at a surprising 1.8 bar which for a standard car really is amazing."

^^^^ Love your sig! My last car was an mr-2 turbo, and I completely agree!

 

^^^ You know it!

 

AMS should be able to answer this.

 

My previous car to the MR2 was a RX7 twin turbo.

Driving an RX7 is like killing someone with a pipe-bomb. Its fun and exciting, as long as it doesn't blow up in your face.

 

lol. my dream car was always the rx7. now that i finally could afford one, i would not buy one as they are REALLY unreliable.

To answer your question succinctly, I did not.
However, because you asked the question, I got to thinking about it and decided to check the boost in each of the three modes.

With the electronics doing the shifting:

In normal mode: the boost was highest at 3500 rpm about 24 psi, then it tapered down to about 19 as the revs build up

In sport mode: the boost is about the same as normal mode

In S-sport mode: boost is about the same initially and then remains at the lower 20-19 psi this appears to be because the engine remains at the top of the revs with the close gear ratios.

With manual shift activated, I brought the revs up to redline in each mode in first and second gears, the boost value was virtually identical within the three modes

I was only able collect data through first and second gears, (don't need to break the law) although I expect that the results from longer pulls would be the same.

So there you have it, the boost remains the same regardless of the trans mode.

By the way, 1.3 bar = 18.9 psi / 1.5 bar = 21.7 psi / 1.8 bar = 26.1 psi, I don't think we can run this high boost level on 91 octane with a stock FMIC!
