ideally you dont want to drop the compression ratio...it ruins drivability when off boost/crusing.
theres to ways to do this:
1)the proper way
2)the non-proper way i.e. little attention to detail
bodged way: drop Cr, by either a thicker head gasket, or a spacer and gaskets. this is poor...
hydrogen will be the future race fuel...i'll make sure of it! its a very suitable fuel.
cars have been made to run on water where the electrolysis seperation of water is carried out on board....ive seen videos....BUT for performnace use, i doubt the rate of production would match the rate of...
u'll need ecu and ignition master switch with key/transponder (its immobilised unless u have this), and he better be good at wiring.
or put it on bodies with standalone ecu
full race spec. was for "hot hatch" race series
in short:
1.4 8v
massive valves, fully ported VTS head
1.2 crank
1.4 block bored to take disp back to 1.4 (for regs, since we used short throw crank)
JE pistons, CR= 12.7:1
crazy cam (cant mind on exact spec, but it was something like 13mm...
Thats not exaxtly true mate.
as ben says, static Cr is meaningless pretty much. with your examples...if u had say 10:1 static Cr and a low duration cam profile, it could work out that your dynamic Cr is greater than a set-up with a static Cr of 11.5:1 and a higher duration cam profile. Thsi...
To do that you would need a pre-programmed relationship between the value the lambda sensor was reading and the desired AFR (usually 12.8:1 for max power). for example, say you calibrated the correction (via your interception box of tricks) on the lambda sensor to give 10% richness...this may...
are the two engines of the same injection type? eg fuel stratified etc
if not you will have problems. diesel engine control is far more complex than petrol.
i have a hard job keeping up thats why! joke!
im actually tooooo busy reading all my books!
in all honesty i wish i had time to read books....everythings flat out at the moment....
yes you get a selection of maps....none of which are anybetter than an off-the-shelf-chip. the advantage of this is that you can tweak the maps to be ideal for your engine. but, likke i say you need to know wot your doing.
mapping isnt difficult if you know wot your doing, but this system...
It has data-loggong capabilities....so you run the engine over the load/speed sites you want to query/adjust then play back the run on the DL function, then adjust accordingly. you need a wideband lambda sensor.
I had one for my previous set-up. its very comprehensive although a little...
