itll defo give u that boost.
A/R ratio determines how well the turbo will perform with respect to boost and response.
dunno wot would be suitable tho, as proper testing needs to be carried out to determine mass flow rates using temperature and pressure ratios to "match" the turbo to the engine.
thats wot happens when u increase cam duration----less torque at lower engine speeds.
correct setting up will help things, but the power-band will still be higher up
wont give u any more lag.
boost threshold will determine how much torque is lost lower down RPM range due to high duration. seen as there will be usable boost usually circa 2-3k, this will provide torque even if duration doesnt give it till l8r on in RPM range.
turbo cams dont nned to be so...
set crank 2 TDC on exhst stroke. this is where both valves r open--overlap.
get figure for lift at TDC for each valve, adjust vernier 2 give this lift @TDC.
doesnt matter which valves u measure as long as that piston is on exhst stroke.
there is lift at TDC, hence this timing method!!
do u mean actual NOS (Nitrous Oxides Systems) jets?-----no idea, fone NOS
or jets 2 make ur own system?------use carb jets, Weber for example, find ur local Weber dealer.
there was another type on ebay, same thing claiming 200CFM IIRC.
right,
take F7P: 1764cc
say it runs @ 8000 RPM
there r 2 induction strokes/rev, so with 1 revolution there will be 2x441 (1764/4) = 882cc
therefore in 1min: 882x8000 = 7056000cc will be induced
now, 1ft = 30.48cm, so...
^^^^^
its getting too much hot air.........could be weather, could be from engine bay if its an open IK.
this means air is less dense, blah, blah----less power
wot lift do they give? is ur head standard?
basically, to lift max. power RPM (forgetting about mechanical side for a second) u need to increase mass airflow through the head.
so it really depends how well these cams do this. if they state 2-6.5k power-band then thats wot theyll give. to...
is there a scrap metal place round u?? or a farm suppliers??
either of which will have a weighbridge to way goods goin in or out........
just sweet-talk the honey doing the invoices, in2 letting u "quickly put ur car on"!!
