interested! cant wait to see it!
do not confuse pressure with flow... they are NOT the same thingI get what your saying dude
but in a boosted application it doesnt really apply
air fills up the mass after a few seconds of being under pressure
its not like water, it doesnt contantly flow
it equally presses out in all directions...so no matter what length of the individual runners/etc...you will always get the same amount of boosted air going into each cylinder
I dont know much about the gtr you are referring to, so I dont know its turbo...in a N/A application where the air is being sucked in it would be advantageous, but in a boosted application it doesnt really make a difference except for the few seconds you are spooling up
a straight through equal length runner (like the 626) would work great
you are right about it, it has advantages, but only for a few seconds while you are spooling up boost...afterwards that whole space throughout the pipes and in the manifold all has equal pressure throughout it...granted you start to loose pressure after multiple feet of distance (i.e. your gonna have more pressure by the turbo than by the throttle body)....but between the opening of the manifold and the last cylinder's runner isnt enough to really make any difference at all
.do not confuse pressure with flow... they are NOT the same thing
I know the difference between pressure and flow...
but your arguement still only applies to n/a cars
...the difference between the amount of airflow into the final runner vs. the amount of airflow into the first runner is so minimal that it wouldnt make a difference to have a 626 style vs the gt-r's varied style
honestly, I think these guys would be best off taking a 626 manifold and retrofitting it so the egr is in the same location as on the msp...and then reselling it ported and polished...they would make a killing and it would make our lives much easier...
yea that may be true, but the people who will be interested in seeing that extra 5 hp and have the money to throw into that without worry are the guys that already have serious mods done...and those that have serious mods done are propbably pushing more boostThat is arguable... would depend on the car, boost level, setup, and could only be decided by some real world testing. My opinion is that it matters more than you think it does, especially the higher you go in boost and power.
neox.286 said:I doubt the numbers will be great enough different to justify spending well over 100 to 200 dollars more when you can sacrifice 5 hp to get the 626 instead.
when designing the new IM, make the EGR an option. unlike most people, i took off my egr cuz it didnt work with my turbo setup.
I should have a bit of information to post up here within the next few weeks. I need to finish up the fixture so I can make sure the EGR/TB are in the proper locations. I have a bunch of materials for the 3 manifold prototypes for the ideas I would like to try out. This is going to take some time.
How many of you out there are running non standard injectors on your MSP?

Plugging/blocking off the EGR will be easy enough for anyone to do. We are trying to get a setup which allows you keep the emissions controls if they are needed.
