I hope to see similar figures with mine.

The graph :) Spools around 500rpm faster than that on the road.

Do you ever wish it was manual? Trying to decide whether to go single with my car but it being an auto makes me hesitant. I guess one day I need to get a ride out in a single auto and a single manual.

Id recommended tagging along to a meet and going out for a passenger ride in a few cars to experience different setups before righting anything off.

Yeah, it's definitely on my to-do list.

Will have to try get some videos.

So was that the turbo maxed out, what ethanol % did you run ?

For what is supposed to be rated as a '900bhp' turbo, i'm not seeing the figures I want. I may have to step upto 6870 territory, or am I missing something guys?

The turbo could run more on a built engine, but on a stock engine the turbo runs out of efficency after 1.8bar. Budz86 has a built engine and 6466 he made over 800bhp but couldn't go anymore because he maxed his 1100cc injectors out.

Think it was a 70% mix.

We were fighting with the auto gearbox a bit but once it's sorted with put it back on the dyno.

They never quite reach the max they are rated to but would expect this turbo to do around 800-820 at the hubs with the right spec

Deans got close, just his clutch gave up.

It's not always about peak power though it what it does under that.

This turbo spools very well and has a great torque curve

Definitely spools well, its making 300bhp before 4krpm, I bet it's very responsive.

Sorry Bailey's, I didn't mean to hijack, I just really wanted these 6466 turbos to flow a little more top end, great results :thumbs:

Nice result that :) have you got the afr/boost graph

Chris Bailey

Updated with graphs, notice the power and torque drop at 4k rpm. This is due to a gearbox fault, which will be getting fixed ASAP. Then its back on the hub dyno to finish mapping

It does indeed! Might be even more lovely without the gearbox fault.

A VVTi head and that thing will make peak tq before 4k

Let me get the gearbox sorted first and then we can see where we are performance wise. I hope you can show us some roads that I will be able to test properly on Dragonball.

I will John ... even some nice tunnels ;)
