Dyno sheets and discussion for UK Rotaries!

[Prof]

Not too bothered Brett - when the new tubby comes it will definetely be going up.  Just need the old turbo to last until then.

Just been sorting out some silicon hosing, and shiny metal pipe for a modified inlet duct - going to get rid of that hideous double 90 degree bend and just have a single 45 degree in it.

[Brett]

:yes  Thats the way!

[Tintin]

Found this site today , has some very interesting reading in the technical articles regarding BHP torque and wheel v\'s fly figures

sorry if this has been posted before , didn\'t have time to read 20 pages to check

Mapping session today...

401atw @ 0.6bar(7300rpm)
408atw @ 0.8bar(7300rpm)
420atw @ 0.9bar(7300rpm)

430.5atw @ 0.91bar(7500rpm) 360ftlb @ 7500rpm

I still hav\'nt found peak power or peak torque, as both are still climbing at this RPM although torque is starting to level off.
Will post up graph when scanned.
Cheers,

John

Impressive figures John - what do you reckon it will rev to ?

[88GT-R]

She will rev round to 8, but i would rather do that on another day!! The steel seals are the limiting factor. I reckon the engine is producing peak power between 7800 and 8200. Without increasing the boost, there should be another 20-35atw to be had.
