Hello everyone,
I have been following the thread on the Dyno days with great interest but one thing that I don't understand is the relatively low Torque figure that tuned RB26's give. Don't get me wrong but compared to its BHP the figures are not so impressive.
can anyone explain why the RB (straight 6) should be sitting 100lb/ft below (roughly) when something like a porsche Flat 6 has got a higher torque figure than BHP ?
why do things like big block chevy lumps give such high torque, V6 ? there must be ways of manipulating these figures with cam/timing fettling.. as per Gary and others.
I don't disbelieve any of the Statements made regarding the power and Torque of anyones car but I believe that it is simply a case of researching which cams give the highest torque.
Until recently (1 year or so) the main focus has been on big BHP but now the stance has shifted, and rightly so, toward the quest for torque, could it be that we are not too far along the road for torque as everyone's attention has been diverted looking for ponies ?
I think that while most have gone for big power at high revs we should be producing max power at 5000 or whatever as per the dyno comparisons for torque and BHP meet.
This is going to be less stressful on the engine and make the cars quieter !!
if you change the cams so the BHP comes in at say 7000 rpm then does this magical 5000 odd number change or is this a fixed point in the curve. (I am talking about the point that BHP and Torque are the same)
thanks for any input...
