my last setup (td04 on a 1.3) would register about -5psi (ie, vacuum) at 65 mph cruise, and would,nt show any boost till about 80 mphAnother thing I've noticed is just how easy this little gt15 spools.
Now I have two routes to work. The most direct is jumping on the motorway 5 minutes from my house and exiting the motorway 10 minutes from my work.
Or back roads way which as long as you don't get stuck behind a lorry or tractor is nearly as quick.
On dual carriageways I've noticed holding the car at 70mph means 2.5-3 psi of boost part throttle. This constantly for about 10 minutes doesn't sound too good to me with my limited fuel setup, whereas I can drive on and off boost the back roads way as I please.
An idea I had to solve this is to fit a twist locking choke cable to the wastegate to hold it open and reduce boost on the motorway.
If anyone could offer some insight on this whether or not they think I'm a moron or not feel free, the choke cable will be here for next weekend
Also did a plug check with some new plugs I fitted during the turbo fitting. Seem spot on to be honest, if a smidge rich on idle. They're looking a little warm on heat range, which isn't alarm bells but with a conservative setup I need to err on the side of caution so I'll be picking one step closer plugs tomorrow and I'll just have to hope I don't have problems with fouling.

ahh, its chargepipe pressure you are seeing then mate (pre throttleplate) you need to read mani pressure on a petrol engine really, because of the throttleplateI've got it piped into a T piece on the wastegate line between the wastegate nipple and the nipple on on the turbo itself. I didn't want to tap off the fpr feed as I've already tee'd into this for the rrfpr so don't want to 'overload' this source.

yes, at cruise you probably have +2 psi blowing onto the front of the throttle plate, and about -5 psi sucking against the back of the throttle plateAhhhh so mani pressure may actually show a lot less under these conditions?
Good to know. To be honest I'll leave it how it is for now, it's working fine and being a pressure gauge rather than compound gauge I don't know if it'll like vacuum pulling on it.

From where to get tacho clocks?As you can see I also haggard cut the grill out nismo-esque. Not sure if I regret that decision or not!
Personally I'm more about how the car feels to drive rather than chasing speed and grip etc so next up was changing things up for driver feel.
Got myself a racing steering wheel (budget but quality from McGill Motorsport I believe)
Also got a new gear knob which there's a photo of later.
Bought some JDM porn for inspiration:
And fitted some tacho clocks:
