Updated graph - no wheelies this time!

Thats some monster power

I bet thats bloody quick What turbo is that with gt??

fantasic results

Ben

Very nice Matty What turbo have you slapped on there then? 2871? 3071? 3076?

Also, what is with the dip in power between 4 - 4.5krpm?

Great result, crazy 112bhp transmition loss though ??

Nice coloured lines ....

Indeed. I think she may have spun the wheels....

I had a 155bhp metro (stop sniggering!) that made about 210hp on its first run when it spun the wheels lol.

GT3071 Alexis. The dip in power is due to overfuelling again

I'll iron that out next week, although I can see me doing a few runs today as I clearly must have spun the wheels.

It's quite a different drive compared to my GT28RSR, it doesn't feel quicker as such until you look at the speedo.

Get that Q+ sorted out then, chop chop Seeing a graph like that is getting me excited to get my 3076 running What boost you running too?

EDIT : How are you finding the boost control of this turbo? As i know Fergie had issues controlling it as i think it was down to a too small internal wastegate hole.

I wouldn't expect any answers soon Beggars. It'll be in a million billion itty bitty pieces by the end of the week anyway.

You mean like this

Yes, I'm expecting to see a similar sight out my window at some point today if he's on the rollers again.....

Haven't you heard................









Only joking! When it does go pop though, it will make for an interesting rebuild

Hmmm yes it's a bit of a beast to control. For instance the actuator is set at 1 bar, however at high revs it won't go below 1.3 bar...

Above 5k it's a bloody animal, I can only imagine how the 3076 will be.

Sounds like you have the same problem as Fergie then. You need to port the internal wastegate hole, as it can't get rid of the excessive exhaust gas quick enough, hence the higher boost

Well Done Matty, at this rate the picture below might become a reality

Clicky

That 112hp transmission loss seems strange to me too...

Surely, as the dyno only reads the power at the wheels, that is the only reliable figure. The engine figure is an "estimate" based on the resistance in the gearbox.

If the wheels were spinning on the dyno, the wheel figure would show marked dips where it starts spinning.

I did a couple of runs last night, and I've updated the graph at the start of this thread.

Still major over-fuelling but I'll get that sorted out soon...

Thats a bit better now.

Think you should get the wastegate hole ported though like Begbie says, so it will make it nice and smooth!!!!

After some long hours last night I've managed to sort the fueling at midrange now, and the top end.

Before

After

It's quite frisky.
