Trottle Pot Rover V8 Pre / Serp Engines whats the difference

[Tom The Cat]

Hi Chaps,

I wonder what's the difference between this tow POT's

THROTTLE POTENTIOMETER : TVR PART No. E0206
Part No E0206
Throttle potentiometer for pre-serpentine V8 engined models, Griffith and Chimaera.


and


Griffith > Engine and ancillaries

THROTTLE POT SERPENTINE TVR PART No E0467
Part No E0467
Throttle potentiometer for serpentine engined TVR Chimaera and Griffiths.


Maybe silly a question, but is it only the Plug?

Thanks in advance TTC

thanks Blitz
Yes the Better Price! that's for sure!
but,
what's makes the second one much much more expensive?

I bought one of these and it had not just a flat spot but the engine totally tried to cut out, push through and bang full throttle. I bought another and sent it back as they would not accept that it didn't work as its not listed for a TVR, put on the old worn one and back to normal. Put on the next one sent almost exactly the same! Bought a lucas and all was correct. Put the paddock one on my mates range rover and no problems???? he has a spare now FOC I was a lot lighter in pocket although to be fair paddock refunded one of the purchases. Blitz it totally confused me If I had known you then I would have sent it to you for testing.

Its nothing more than a variable resistor with a certain sweep in degrees and resistance value. There should not be any compatabilty differences between a Range Rover or TVR- its function is exactly the same. Only difference might be the TVR engine bay runs hotter if the componet is heat sensitive- not that this should be the case. If you get flat spots it would imply the TP is going open circuit at certain throttle openings, and would therefore be deemed faulty.

I agree, I have no explanation. Why did it work on the rangie? don't know that either. I will ask and see if he used it, if not I will gladly sent it to you.

Apart from the connector, some have slotted holes so they can be adjusted & some dont (so you have to use a drill to set them).

Hi Spend,
are you really sure, Did you tried it?
You know if the range(example 10 - 680 Ohms)by both the same?
and as you wrote just drilling a bit for finding the "SetPoint" ; 0 - 90 degrees) , ok!

that's why a ask you again : you are sure the both types have the same specification ?
Thanks in advance TTC

The elongated holes are for the 14CU ecu used on the late 3.5 engines, because you needed to set the throttle shut voltage manually. The 14CUX used on the 3.9 onwards will auto adjust, so they took the elongated holes away. You can use either on the 14CUX but if the holes are elongated you will need to set the voltage to within the calibration range the 14CUX can cope with. The resistance and sweep remain the same, although the connectors do change to answer the question.
