so after all of this did you play around with end of injector timming at all
-
im using 1000cc out boards and 650cc inboards both sets are running different end of injection timing and im at 75psi ,motor idles at 950 rpm out boards are dribbling on idle .my whole set up is blended in from idle up to 9200 rpm on the 2 litre .at 100 percent throttle its 95 percent out boards and 5 percent inboards .injectors are out board is a single pintle so cone type, and inboard is a similar to the 7mgte types my inboards are from end of injection timing 185 to 95 up at 9200 the outboards are from 340 to 230 at 9200

so your last test was with out the air box ,so you need a box as big as will fit, plus enough air going into so its the same as no air box ,thats what i would like to see
-
now you need too try 6 inch hole into your airbox
-
in the pic you can see the map sensor hose and air temp
-
-
you can cheat ,how many injectors are you using at the moment
-
and iii will show pics
-
and here these are fixed but gives you a idea
-
have a look here
-
also have a look at the superbikes ram tube set ups a ramtube in a ram tube
-
ok fair enough, i use to use a 100mm dia tube going into my air box at the race track ,we put the map sensor into the side to check the air volume so at idle etc was on 100 at 50 percent throttle was 95 at 100 percent throttle is went down to 80 ,i then put a 6inch hole into my air box and the map sensor stays at 100 from idle all the way to 9200 redline
-
kpr was your air intake running in colder air also were you using your map inside to see if it was holding the air back from entering your new air box on ram tubes i try to have then 60mm away from any part of the air box lid
-
yeah 4 inch is 2 small .yowzer with colder air temps going in more fuel and ign timming gave more hp
-
yeah i picked up more power and torque
-
-
-
im using my map and air temp inside the air box ,but i also dropped 20c in air temp as my intake is in front of the radiator ,so on 25 degree days it sits at about 20c coming in past the air temp , before the airbox radiant heat was up to 40 c going past the air inlet
-
oh ok fine then ,i tried 48mm quad 50 mm quads and 52mm quads on my 2 litre beams and the 50mm were the best after 7600 rpm ,mine redlines at 9200 where max hp is
-
my air box is 12litres in volume and im using 150mm dia piping going in with a big K&N filter and 2 stage inside
-
im talking about midrange power that pulls you out of the corner ,what size exhaust are you running as well
-
ok so if your car was a race car and was at tight race tracks the 47mm throttles would be faster coming out of the corners and in lap times as well
-
kpr you said you went from toyota throttles up to 52mm did you notice your torque dropped at all ,also do you think you have lost airspeed by going up to a bigger throttle as well
-
its always good to read what others are doing ,my 3sge is trd inlet, 50mm throttle taper out to 52mm. 2stage is 52mm out to 55mm and ram tube is 55mm out to 65mm with 8 injectors ,the other 4 are 230mm further away than the inboards ,i still get some misting or stand off at about 7000 and also i use to lean 1 cyl out in 500rpm range .i tune every cyl now from idle to redline with my big air box on ...the biggest difference on using inboards only or out boards only is about more torque and more hp ,about 12kws across the rev range higher than just inboards

w58 box and 3s bellhousing and y ou will have heaps of room
