Do you know if Speed Hut will be making a flat adapter ring? I just need to replace my speedometer (at least for now).
I would buy one.
Yep. Me too.
"mardyn" could you share why SH did not go with the 5" speedo and the flat bottom tach at the onset of the project ? I for one like to keep Kip Ewings' CF 2 piece dash plates in my car with the potential SH gauge install, even if mine are still intact (-oh boy I hope I didn't jinx myself-)
My guess is tooling and one-off associated cost. A 4" housing could possibly be used on many other applications.

More to come later... I'm neck deep in our home building project today.
btw... Speed Hut 30 psi boost gauge is in the initial phase of development.
Patience.

Just sayin! 30 aint going to be enough..........If the output of a 30 psig sending unit is the same as that on a 15, why would any electronics have to change? - just a different scale on the meter would be required.
Or don't I understand the problem?

How hard could it be to gut out the 4 in . Speed hut tach and swap the workings into the back of a gutted Ford tach? A leading question, since I haven't had the need yet to get the dash, but there's only 1 moving part essentially, right? I think the right electronics geek could add a pot or something to re-cal the needle swing. Then we'd have a reliable OEM looking tach.

My full set is to ship today according to Speedhut. 4 or 5 more days and Kendall can install.....Gas gauge died so I'll change out the whole set to save. Using the black frame with silver bezels.
I understand that they are trying to accommodate the
requests for the 30 psi boost gauge as well as a larger diameter speedometer.
All my Speed Hut stuff is still operating at 100% and I'm very pleased.
My next project is to do the gauge panel with (either) a carbon fiber overlay or hydro-dip/clear coat.
My house project is on the front burner right now though... the car has to wait.

Just got a call from Speedhut, gauges should ship monday, coming with 41/2" speedometer. The 30 lb. boost gauge will use the original harness for power but will use their sender for boost reading. I was thinking about tapping the power brake vacuum hose for the sender since it is closer to the gauge. Running the wires from the engine would seem more of a problem. I used the brake vacuum on my Viper and never had a problem. Any ideas?

Their sender is mechanical? (I may be reading that wrong)
Can't they use the factory lead and their sender together?
The gauge is all electronic, they just can't use the stock sensor. You have to use their sensor. The problem is finding a convenient vacuum source and running the new harness to the dash. My thinking was the vacuum to the brakes was the most convenient.
It's not as easy as just replacing the existing OEM sensor.
I believe the OEM signal from the PCM is maxxed out at around 15psi, hence the need
for another sensor. ( As I understand it, the OEM boost gauge reading is not actual manifold pressure, but a calculation
of boost/vacuum based on flow through the MAF sensor....[somebody correct me if I'm wrong here])
So, you're actually installing an additional sensor to monitor real time manifold pressure
and convert it to a signal that can be displayed by the 30 psi boost gauge on the dash panel..
If you've got the skills necessary to replace the gauge(s), certainly installing
an additional sensor would be a walk in the park. The idea of locating it near the booster
vacuum supply/close to the dash panel (maybe even on the back side of the dash panel) seems to make sense as well.
Although I have not seen one of the 30 psi boost gauges from Speed Hut yet, I believe it will simply
plug into the existing GT main dash harness just like the other gauges, but would require only one additional
wire connection directly from the new sensor to the gauge.
I hope some of y'all will post up some pics when you get 'em in hand.
Happy Thanksgiving!
