That's interesting.. not trying to derail this, but I wonder if the K14 having more fins makes it spool better than the VF14 with a diesel's low CFM? My K14 is much more responsive than Ed's T3 and they have a similar compressor map
how could a K14 and T3 be similar? one is WAY way bigger than the other. a K14 is equivalent to a T2, K24 being equal to a T3. K26 being equivalent to a T3/T4?
i hate to argue with you about turbos, but i just dont see it possible to have them be even close to similar.
I believe the T3 used on VW 1.6's is a 45 trim. Look at the compressor map
here compared to a K14
here. To convert lb/min to m^3/s, divide by 162.
The T3 is capable of a higher pressure ratio, but the efficiency drops off faster at higher flow. A 1.6TD is small enough you should be able to get more boost from a T3, but on say a 1.8L gas motor, you might get more boost from the K14
A T3 60trim is significantly larger than both of those though
There are million different K14īs. You think that K14-2464 is the one with 1,6TD?
I have installed the mercedes 24v k14 on my xud 1.9idi so this could be relevant to aaz owners, it was a big upgrade over the standard k14/t2 even though Ive sort of messed up the hotside a/r by opening out the smaller k14 one to take the merc cartridge. It is laggy a little between gear changes but will make full boost at around 3k rpm and the car pulls well to 5.5krpm with no surge. The car made 173bhp at the crank with this turbo at around 29-30psi but I'm 100% sure it will make more next time with more fuel, its as clean as a whistle on boost
More experiments to come once the new engine/egt is in.
Wheel sizes are (roughly lol):
Turb. In52mm-ex48mm
Comp. In43mm-Ex60mm
Can somebody interpret how a trim number relates to the size of the blades it represents?
