GTFO Jay ceffies are lighter and 2L (get back to turbo section )
p.s - i can get 600 on the highway too, i'm talking around the city
i know what you mean by driving it "off" boost, but you are incorporating too many variables and not enough controls to "compare" them.
and yes cubes i know they make less torque/power if you keep it at low revs.
when gearbox's are slightly different, injectors, compression, etc etc. - there's too much stuff to take into consideration
ok THEORETICALLY
ie. for the purposes of comparisson... we have two cars
R33 GTS25 (RB25DE) and an R33 GTS25T (RB25DET)
stock for stock...
if we fill up the fuel tanks with say 10L 98RON each.
and drive them both down the highway...
both changing gears at 4000rpm (or even 5000rpm)
now here's teh tricky bit - the GTS25T will pull away and assuming both cars maintain the same driving style - but who will consume 10L first?
now... lets say rev to 3000rpm for each gear change.
the GTS25 will pull away... as the GTS25T doesnt boost.
will the GTST25T save enough fuel driving off boost??
which will have better economy in the end? see what i mean?
i'm not saying your wrong and i'm right, but your claim as to having
close to same fuel economy needs proof.
hope this sparks more debate
