Too many posts.. I need a life!!
i am not saying they are no good just if you are tuning an engine why not get some good gains from the manifold too
peeps spend alot of money building good power cosworths and dont look at the manifold thats all
when you can get 40+ bhp out of one

lol did you try your engine with the 2wd first ?? before the tubular

Right whats the better manifold to use if im not going over 400bhp, i have 4x4 one on at the moment but i have a spare 2wd one, my cars nothing special just a bit more than stg 3, would i benefit from using my 2wd one and where would i see the difference

But thats were a tubular will be better again

...ok ok...look...the 2wd manifold is only effcient to around 550bhp as i keep saying...why would you want to go over this as you are having to use more boost to acheive the goal....now more boost is surely more strain on componants especially head gaskets..not to mention more heat..so yes using a 2wd manifold past 550bhp is stupid 
So if you spec an engine over this then the engine is flawed and as the geezer above says you spend all this cash on a big power motor and leave a stock manifold on
My own car would need 2.5bar boost from my GT35 to reach 570-580bhp
...put the tubular manifold on and your now seeing less boost to acheive that bhp and less strain....personally i wont run above 2bar so i am not over the safe threshold of the manifold.

mad enough for my car to come off a trailer, do 5 runs down a run way running 2.5 bar, do a very impreressive top speed for my power and go back on the trailer without even checking the oil
im a nutter
if you have tested back pressure and EGT and find no problems then why change the manifold??? oh wait...cos someone on passionford says so

but euan you are well within the bhp tolerences..so where is your gripe? ...however to have only 500 or so bhp at the fly with 2.5bar shows me you are trying to eek everything out of a turbo when in reality you aint gaining that much over 2.1 bar....fit a bigger turbo...a GT30 would see the 550bhp limit much easier than trying to force the t4 to its knees

the previous post said i was mad for having a 2wd ex manifold if power was around 500-550 bhp.
My car runs 60 bhp more ATW than mikes saf did on same rollers so that in "theory" makes my car 575 bhp on a dyno.
Watch this space for even more power, still with the 2wd manifold.
i understand what you are saying about the T4 but we are seeing how far we can go without changing the the turbo.

...no because rolling roads vary too much to be accurate...dyno is the only real measure and even then you have to calculate the losses from certain parts once incar.
..its how it goes and yours certainly does

i should have very little losses/restrictions due to parts connected to the engine once the next step of mods are complete.

...the 2wd manifold is a flaw past 550bhp where you are having to push more boost than you should compromising reliability.
..the t4 turbo in grp a trim is capable of 540bhp on sul a std t4 around 500bhp reliably!
Gareth its impossible to give an accurate answer to your losses question...the best idea is to dyno with power steering pump/alternator with all belts on and to use the same diameter exhaust.
