Fuel pressure? The one in the console is for boost.

I've got nothing to control the VVT at the moment, thinking of buing vvtuner.

 

I vote this for the ugliest boost gauge install ever. It sure looks like a fuel pressure gauge though.

 

who uses a liquid filled gauge for boost?

 

Man I love how your car looks, but that "boost" gauge is terrible. Like really bad. Go buy a cheap *** prosport gauge or something asap and remove that hideous lesion from your dash!

 

or get the one that matches the rest...

 

That is a beautiful Miata, but that dyno graph looks all kinds of fucked up. Giant torque peak then nothing, peak HP at 5500? Must have been interesting to drive

 

it's probably making like 16-17psi then dropping to ten by redline. Peak HP should happen somwhere at 6500-7000 RPM, not from 5000rpm TO 7000RPM.

 

I'm driving with 0,7 to 0,8 bar boost pressure. If i raise the pressure the iat:s start to raise fast and I'm not getting not much more power (10-20hp for 0,2-0,4bar).

And yes, the boost pressure drops going forwards to redline. I think I'll try to take the wastegate actuator signal from the plenum side, not on the compressor housing as it is now.

 

Turbo boost drop fixed with an EBC

 

Dp

 

wow that plot just dives past 6500

otherwise good improvement, congrats

are you still not controlling vvt? doesnt' look like it the way your torque is shaped

 

Clean car, good improvements for sure. Looks like typically greddy dive towards redline, just worse with the VVT?

 

It has been a long time since last update, some pics:



Painted the car with macadamia metallic.


Diy frame rails

Added one diagonal pipe for the TR lane roll cage + welded the cage in.




Supports for the front splitter







And made wing mounts from aluminium + bigger splitter from 12mm plywood.

 

I'm liking that boost gauge more and more...

Is it off a Sphygmomanometer?

 

Any better pics of the car in the daylight? Color looks great. I'm torn on this car, on one hand the engine setup and the color of the car look great, on the other the interior looks pieced together.

If this is a track ****, i applaud you. otherwise.. i dont know.

 

And yes it's a track car for the most of the time.

 

Few more pictures, allmost finished for the season.

 

Got any better photos of your manifold that you used to mount the GReddy turbo on the 1.8?

 

Ordered it from Abe, it's the axial replacement for the original greddy manifold but just with the 1.8 flange.
