Need An Rb34 Gtt Dyno With Standard Turbo

[Torques]

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.

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/

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.

Light blue is standard OP6 with supporting mods.

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
