Vf34 or TD05HR-16G?????

[skevosEP91]

Hello guys and greetings from Cyprus once again!!!!

I have a friend with a forged 5E EP85 and will upgrade the turbo(previous was a tdo5 16g subaru turbo) and we are in a dilemma between a vf34 from a Spec-c and a Td05HR-16G from an Evo 9!!!!
The car is a drag car and we launch with 2nd gear due to much wheelspin with 1st so we are confused so to not have very much lag!!!!
Also exhaust manifold will be custom in both situations so it will take place any advice given but to be mentioned that the turbo will be top mounted!!!

Also I need help to upload a dynograph of mine on a forged 4E vf30 setup which made 260whp and want to check with everybody if anything is wrong!!!!


Thanks in advance and any help will be usefull !!!!

also check the other 2 links in that tread

both guys ran evo turbos...maybe those treads will give you some insight

the vf34/35/30 and td05 (stock subaru turbo) should be similar performance wise, but may vary a little bit in terms of overall power/response/lag due to differences in their backend and the car set up

I read somewhere (worst opening ever) that the vf34 is the biggest vf bar the 22, is that right?

i think the vf34/35/30 all seem to be similar apart from backend/turbine differences based on my research. the vf30 seems to be the laggiest of the 3 due to it being journal bearing with a big p18 back end, while the vf35 is said to be responsive due to a smaller p15 backend. the vf34 is ball bearing, but with a p18 exhaust housing, so somewhere between those two

now the vf22 by all reports is laggier than all 3 of the above due to the largest p20 turbine housing, which i suppose would help make a little power in the top end
