Flattest Torque Curve?

[Swiper the Fox]

Running 109 octane is a TOTALLY different kettle of fish

Not correct...

Depends on the engine....a highly efficient engine like ours only see's a difference of 20KW when run on race fuel and BP98...and before you say it...yes that is with timing adjusted.

as i learnt last weekend, adding higher octane fuel can drop power without any timing adjustments

Sorry the topic didnt say anything about pulp only torque curves.. 545hp was at all 4 wheels aswell by the way..

Yeah I don't particularly mind the juice. But your graph while impressive is not flat at all torque wise.

It seems the boost comes on hard at 4000rpm (peak torque) sustains it for maybe 1000rpm then

the torque rolls off - and rolls off fast after 6500rpm.

Reason I'm asking about flat torque curves is this is one attribute always boasted about with good

engines. The 135/335 bmw has a very flat/wide torque curve for instance. "absolutely flat from 1300

to 5000rpm". The R36 is pretty flat from 3000 to 6500.

Whenever you get flat torque curves the engine is always praised for its feel. Look at the tesla. Amazing

torque curve - table top flat from 0rpm to 10k or whatever, trumps its unimpressive max power hands

down, makes the car a super drive perhaps because the urge is entirely linear and predictable.

Hence the question .. what mods (and tune) support "maximum flatness".

how about a weird tune that holds back psi initially, then allows it to rise.. eg boost to 12psi

at 3500 but by 5000 its 18psi and by 7000 23psi..
