Torques Posted December 30, 2014 Share Posted December 30, 2014 Does anybody have a dyno of the GTT with OP6 turbo? (boost curve) I would like to see if that OP6 turbine introduces more lag compared to the R33 turbine.

sleptema Posted December 30, 2014 Share Posted December 30, 2014 I believe the difference between s2 and neo turbos are the material in which they are made, the s2 being made of ceramic where neo is steel.But if you were going to find an answer, it will be here: http://www.sau.com.au/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/ Link to comment https://www.sau.com.au/forums/topic/452193-need-an-rb34-gtt-dyno-with-standard-turbo/#findComment-7452875 Share on other sites More sharing options...

But if you were going to find an answer, it will be here: http://www.sau.com.au/forums/topic/55845-rb25-turbo-upgrade-all-dyno-results/ All wrong. S2 has the original smaller turbine housing. Neo has larger OP6 turbine housing. Actual turbine inside is probably exactly the same ceramic unit. Both have plastic compressor wheels, although I can't say if there is a small spec difference between them - and nobody really cares anyway.

hypergear Posted December 31, 2014 Share Posted December 31, 2014 Light blue is standard OP6 with supporting mods. Link to comment https://www.sau.com.au/forums/topic/452193-need-an-rb34-gtt-dyno-with-standard-turbo/#findComment-7453106 Share on other sites More sharing options...
Ben C34 Posted December 31, 2014 Share Posted December 31, 2014 Why would you bother cracking out the spanners to put a turbo that performs like that and is ready to grenade itself? It takes the same amount of time to put a decent turbo on.

Torques Posted December 31, 2014 Author Share Posted December 31, 2014 (edited) Why would you bother cracking out the spanners to put a turbo that performs like that and is ready to grenade itself? It takes the same amount of time to put a decent turbo on. You are absolutely right. it would make not make much sense. I'm going to install in a new hybrid turbo I got for testing purposes. The hybrid comes with the smaller R33 turbine and I want to swap this turbine with the OP6 (R34 GTT) one. Stao (thanks!) already said the OP6 makes 20-30KW more power. I was just concerned about lag hence-why I asked for a dyno plot. The OP6 is said to have an A/R of .63 vs .50 for the R33 OP6 R33 Difference in turbine housing Edited December 31, 2014 by Torques 1 Link to comment https://www.sau.com.au/forums/topic/452193-need-an-rb34-gtt-dyno-with-standard-turbo/#findComment-7453241 Share on other sites More sharing options...
