colder weather mostely wet||33.21|
||1.298||almost full upper block
lower block lip||34.23|
||1.1299||installed new grillblock, oil change after this tank||35.70|
||1.247||first days of freezing,
slight overfill (should show up on next tank)
otherwise, huge problem||32.13|
||1.232||running lower grill deflectors and full width undertray with small wheeldams||36.44|
||1.305||new grillblock flap on lower grill||35.80|
||1.282||dam experiments hopefully results with the next tank||35.44|
||1.308||took of the wheel dams.
drove a bit un hypermyler like
very hot weather||37.67|
||1.297||short shuttle's to the show (two weeks off)||35.94|
||1.327||driving without side fairings||37.48|
||1.307||still running without sidefairings but wich extended wheel dams
working on now frontal dams||38.72|
||0||building new dams yet again :)||36.52|
||1.204||smooth dams in place 50% topgrillblock.
perhaps a bit of a heavy foot this tank||34.24|
||1.212||return trip from holliday in the ardenes, two days of highway and hill driving||36.12|
||1.185||weather improvements, experi?mented with new dams
||1.169||temps are getting a little warmer.
fixed broken weel dams, added frontal dams, and taped hood seems with wind stripeing||33.56|
||1.14||temperature is getting a bit warmer...
housemoving so lots of short trips etc... also slightly longer work commute still i'm trying to keep up some eco driving||31.92|
||1.138||first "reliable" result of this year... temps are getting slightly better but not the milage... i'm running a grillblock for the topgrill wich doesn't seem to help much, and recently i noticed on of my wheeldams has been broken off... i think i'll revise these once more||30.86|
||1.102||estimate based on what i remember 7.7 l/100km and the data about the previous and next tank|
recovered the data while moveing (forces you to go trough all your stuff)
still my guess was acurate and the milage is bad
combination of partial fillup on 01/17/09 and full fillup on 21/17/09... virtual average of these two filups
somethings needs to be adressed... the car has been returning a crap milage these last months... might be the cold, but i'm not happy with my results
||1.03744||big wheeldams that curve around the wheelwells on the inside in place, side undertray removes
freezing cold, day and night temps don't go above freezing, it's been about -1 to -9 celcius all the time, so FE and aero are on the backburner... i'm glad the car will start in the morning.
it's disapointing this last fillup of 2008 is the worsed ever, but on the other hand fuel prices have gone down... that's no excuse for bad FE but it does make it less of a real problem.
anyway.. lets hope FE will go up again in '09||31.54|
||1.088||very cold winter weather, had to idle for 15 minutes a couple of times just to be able to defrost the windows.
did some wheeldam experiments wich i think didn't went well, new configuration on from this tank on so we'll see if that's an improvement
||1.185||not to happy with the result
quite some experimenting and bad weather over this tank.
i've taken off the rear strakes and revised the wheeldams although i'm not sure if they're ideal yet.
after this fillup i've put the rear wiper back on, as the weather calls for it||34.67|
experimented with sideways extended undertray and various wheeldam and grillblock versions
not to happy with the results so far but cold weather and a lot of short trips might have a part in this.||35.52|
grillblock and tailstrakes near the end of this tank||35.97|
||1.448||some grillblock setup experiments; installed lower wheeldams along with the original's to form a big dam near the end of this tank, also ran a few lites of diesel contaminated fuel , but since i don't know how much, and it seemed to have canceled itself out it's not included here... i don't recomend it however||39.36|
||1.474||fillup upon return||42.64|
||1.26||driveing around the hills in luxembourg||34.14|
||1.292||got 20L on belgian soil to make it to luxemburg. full fillup there, mostely highway||37.33|
||1.504||undertray, rear wiper delete, new front tire, some highway trips hauling furniture on roofracks||38.66|
||1.565||aluminum undertray in place for more than half this tank
about 15L in stock config
30L with full undertray minus wheeldams.
i hope my next tank will bring me around 40mpg|
planning to redo the wheeldams, but a little lower bit brake cooling ducts above them, like i've seen on some VW's
next on the todo list is an active grillblock for the top grill
||1.498||first tank with the partial undertray, not the great improvement i'd hoped for, but not the worst tank either, and considdering the previous thank might have had a fill error this seems ok.
still some revisions in the design might be needed||37.43|
||1.46||fast acceleration in 2nd, and than straight to 5th
small wheeldams still in place||40.05|
||1.44||filled up with 98|
installed wheel dams just before refil
||1.43||1st 1/2 tank... filled op with about 60L of 95ron the 1st time and now refilled with 28L of 98 so that should give me something like 96... see if that makes any difference... car needs 95 so maybe not... but we'll see.||36.96|
