Re: Adapatations to run on unleaded.

I was thinking about pinking due to generally lower octane ratings with unleaded.

Re: Paint spray setup

I recently purchased a turbine HVLP system. The five stage turbine produces 9.5 CFM. I will evaluate it during the repaint of my street rod pickup truck in my garage next week. The advantages over conventional high pressure systems and even intermediate pressure HVLP guns (using a conventional air c...

Re: Help pls - Alternator voltage too high, blowing LEDs?

I couldn't find a data sheet for the dimmer, but one commenter on Amazon said he took one apart and the are three field effect transisters inside. My limited reading on Wikipedia suggests that FETs have an inherent resistance to voltage spikes. So maybe the little dimmer is a sort of blocking device...

Re: Help pls - Alternator voltage too high, blowing LEDs?

Id guess your dimmer device is a variable pulse width modulator type. It very rapidly turns the leds on and off. By varying the relative off and On times the dimming is achieved. If it works then fine. Could you (or perhaps Marek or Ray) speculate as to whether a PWM type dimming device (I'm sure y...

Re: Help pls - Alternator voltage too high, blowing LEDs?

Thanks, Julian. The dimmer device in the photo is presently installed in the tach and speedo circuit, which is indeed "floating" in my installation. It works well in reducing the light intensity. I have no idea if it also serves the function of a limiting driver. (I do know the selected/reduced ligh...

Re: Help pls - Alternator voltage too high, blowing LEDs?

The simple answer is they are not really suitable for use in a vehicle. BOTH sides of the LED bulb here to be isolated from ground. They seem to limit at 350/700/1000 mA which will be for high power leds that will be far too bright for instrument lighting. Buy well designed (not cheapo) led bulbs d...

Re: Help pls - Alternator voltage too high, blowing LEDs?

David, Several years ago and in the same timeframe that I installed the strip LEDs in the tach and speedometer, I built several LED strip light arrays for the boat. At the time, properly stabilized individual bulbs were extremely expensive. My strip light arrays for the boat were all burned out with...

Re: Help pls - Alternator voltage too high, blowing LEDs?

I'm listening! I used LEDs in the instrument lighting circuit only. I missed the caution regarding installation of a device like the PT4115. So far I've had no "bulb" failures in the LED instrument lighting circuit, but I guess it's just a matter of time. Failure of the strip lights in the tach and ...

Re: Clip-On Bullet Mirror

It clears the leading edge of the body seal. The door window frame seal is trimmed back in the area of the mirror bracket. Beats dings down the side of the car, and the window frame seal is simple to replace.

Re: Clip-On Bullet Mirror

I'm using the Tex clip-on, but modified the mounting such that it slides/loops over the leading edge of the window frame instead of gripping from the trailing edge. This keeps it somewhat attached even if it should come loose. The modification involved slicing the bracket lengthwise, and welding in ...

Re: Radio console - speaker cover panels for 3.8

Interesting discussion. My car is 889474. The radio console is the early style with chrome speaker bezels. It uses the brackets BD19049/19050. It does not have the lower mounting studs on the chassis tunnel (or evidence that they were removed). It has arm rests. The ash tray is the interim "oval wit...

Re: Sudden complete loss of fuel delivery

Dirt in the fuel tank could be accumulating on the fuel "sock' at the end of the pickup tube when the engine is running. Falls away when the suction stops. Begin again when the pumps starts drawing fuel. (Assumes the pump is functioning, of course).

Re: Tyres - 205/65R15

My car has Sumitomo 205/65 AS PO2 tires (H rated) on the front and their 205/70 touring tire on the rear. With a 3.07 final drive ratio, the speedometer error is very small (less than 4% by my calculation). The front tires are very responsive with excellent grip. Can't say much about the rear. Steer...

Re: Oh dear what have I done?

I urge you to use the seal kit from Terry's instead of the one from SNG. The one in my car is absolutely leak free. (Presumably your engine builder knows to machine the crank for the new seal...different dimension depending on which kit you use).
