Heat soak in the MS6

[Newf]

So.....it's warming up again. How are the speeds handling the heat?

ouch!

It should be noted that because of the rather rapid and large variance of hp/tq on dyno runs, it's very easy for any manufacturer to show massive gains with any bolt ons. All they'd have to do is compare a heatsoaked run to a cool run, and va la, instant massive gain.

Some manufacturers like CP-E will take the median dyno (one that doesn't show the max gain, but the most reproducible gain), but many will just pick whatever dyno gives the most power...which obviously means it would be possible to show utterly massive gains from just an intake by fiddling with the dyno. (CP-E pointed out you could get a 20 whp difference just by letting the car sit for 10-15 minutes inbetween runs, which confirms this result graphed above)

This problem will only become greater as temps rise higher and higher. Pay very close attention to the shape of the graphs...if the baseline run looks odd, its probably cause the engine was trying to stop detonating.

So how is Heat Soak rectified?

moving the intercooler

and this folks is the single reason why I am very weary of getting another Mazdspeed.

why? you don't think Subaru's or other shitty placed intercoolers' have heatsoak? Well Suby's have a scoop but still, on a hot day you know.

Mazdaspeed6,Volkswagons, msp stock IC. That's why Evo's and Srt-4's come with FMIC's so they don't really experience heatsoak.

All the speed6 needs is a fmic and no more heatsoak will occur. Plus there will be gains, enough to put it at or about the 300hp mark.

You could fab up a sprayer for the TMIC.

moving the intercoolerto the front of teh car.

Vw has a FMIC. No heat soak that I notice yet.

I don't know about the new ones, but like the MSP and older VW's it's a side mount that has shitty placement ,because the bumper etc. blocks most of it.
