| I had in the past a copy of details of experiments carried out by the MG Car Co. in the early 30's, to try and improve the performance of the F engine.The tests and the modifications made were detailed in tabular form on a single sheet MG Car Co drawing.I have mislaid my copy and wondered if somebody out there might have a copy from which I can obtain another copy. |

Can't help you Timothy however this sounds like something which, if it surfaces, Nick may wish to put in the document downloads?

Dear Forum plus Spatek,Ox34 and T. Edwards
As mentioned earlier could you please post information in Info letter 63, 1981.
I can't be the only person who would like to see this too.
All the best.

While on the subject, was the six cylinder F-type engine 50% more powerful than the four cylinder M-type engine?

To rephrase the question -
While on the subject, was the six cylinder F-type engine 50% more powerful than the four cylinder M-type engine when the F-type engine first appeared?

This might depend on which M engine is being compared. Is it the early one, which despite better breathing, a larger carburettor, and a higher compression, still we are told, produced the same 20bhp as a standard Minor engine? Perhaps it should be looked at the other way round so that proportionately the M engine produced 2/3rds of an F = 25 bhp for the pre-12/12 camshaft engine. However, six cylinder engines generally produce less than a third more power than an equivalent four, so 27 bhp for the early engine seems a reasonable conjecture and who knows what for the 12/12 engine.

Here is the info hopefully that Tim was asking about, incidentally Blower quotes the M type as 20bhp and the F type at 37bhp - you do the maths! Terry W

Dear Spatek and Forum:
Thank-you for the F Type engine tuning information.
I am sure other F Type owner will be interested too.
Point of information all engine sizes and car specifications are to be found in car profile on this site.
All the best.

"Special F type power unit",was the title.However the sheet you have sent Terry is only a small part of the data sheet I had.I remember one item was the fitting of double springs on the distributor contact.The sheet was A3 in size,with MG Car Company printed on it.
I will do some more digging here amongst the heaps of paper work I have. |

| I hope you can find the full data sheet but I suspect many F type owners have done some of the modifications already Terry W. |

Timothy
Rather than post it on the forum, if you have it scanned and send it to me I will put it in Document downloads so that it will be more easily found in the future.
