Could you post up some pics of your turbo inlet please, curious about the shifter cables going over that big tube!!!

Rob, I haven't got any good installed pictures and it's buried under the charge pipe now. The following best shows what's happening

The bracket mounts onto the two boltholes in the gearbox casing that the original shifter cable bracket used. The boltholes sit up on lugs - that's why there is room for the hose to protrude below the bracket.
The compressor inlet is about 100mm forward from the face of the bracket.

The cable holes have been moved since this picture was taken. The forward one is now upright. The rearward one has been moved backwards.

The following picture I posted is misleading: The short length of straight hose on the compressor inlet was trimmed after I took the picture so that it would join the elbow hose.

So it fits and gear selection works as normal? I wouldn't have thought the cables were long enough to pass over the top!

The front to back cable is absolutely fine, Rob. When I got the bracket altered, the welder did not move the side to side bracket back as far as I wanted so the cable is 'just' streched, making reverse selection interesting.

I need to take it all off when the 3" ATP inlet adaptor turns up (I'm running a silicon sleeve on the stardard on atm) at which time I'll get this moved back 10mm which will take the stretch off the cable.

The front to back cable rubber boot just rubs on a little bypass hose at the bottom (I've got the hose pulled in 5mm with a cable tie atm to solve it). This would not be an issue if I had a short shifter.

I really need a 225 ml nozzle Phil. Bill's got a 175 ml nozzle so I'm going to try that for now. I reckon it'll put me at about 80% of the required wmi.

Then I can start logging again. :D

I don't know how much difference the big inlet will make, I guess it will remove a little bit of turbulence from in front of the compressor.

Cool, its a start really, better than drowing the cylinders. You'll probably get more cooling i guess with the smaller nozzle but it'll be interesting to see how it performs.

Shame your miles away from me i'm running a RR day week sunday at Westec that you could have run at to get a proper figure. lol.

that atp 3" adapter never used to be like that! did you order it with the ticker end? or have they changed it?

i thought you currently have this new TIP fitted? or is it currently clamped around a smaller inlet adapter?

That's how it came from ATP.

I currently have the small adapter fitted. I have a sleeve of 60mm silicon around it, with a 70-80 adapter (only about 30mm length of 70mm dia) clamped on that. The rest of my pipework is 80mm.

I can now alter it so it's all 80mm.

yah you should see a slight gain and better spool i would think, turbo may sound a bit louder too
