Hi all,

Someone knows the history of a nova motor?

Furthermore, if we can have information on a website, please tell me.

Especially my interest is for lotus TC engines.

I'm research on various Lotus twin cam engine at that time

Thank you.

Hiro

Hiro,

There was a brief discussion on "another forum" earlier this year:

Also Novamotor Lotus gets a mention on this forum too:

Cheers,

Hi Peter,

Thank you for the information.

The engine appeared for the first time seems to be the 1972 lotus 73.

Does anyone know Nova motor Lotus twin cam engine specification?

I will ask by another topic about other company one.

Kindest regards,

Hiro

William Taylor's (no relation!) The Lotus Book tells us that there were only two Type 73s built, for F2 in 1972 and shows a couple of photos of the Novamotor T/C. He says it had Kugelfisher fuel injection and gave 130bhp (which seems pretty useless to me, surely an error).

One of the photos shows that the toll-hoop rearward bracing struts were bolted to the cam-cover studs... talk about making a component do more than one job!

 

By 1973, the Type 74 F2 car was using a Novamotor Lotus 907 engine and he says they were getting 275bhp from 1973cc.

No not a mistake  don't forget F3 engines had a tiny air restrictor and was 1600cc at that time.

Dave Walker used a Novamotor-tuned engine in his dominant F3 year of 1971, and many others used Novamotor-tuned engines in the 1600 cc F3 1971-73. Were these not based on Lotus T/C engines?

Hi Pete,

Thank you for the information.

Now I have checked William Taylor's The Lotus Book.

Coincidentally, I'm asking EHRLICH by another topic.

Dr Erhlich seems to bought the two Lotus 73 F3 cars.

This mean He did swap NOVA motor to his own EHRLICH Lotus TC engine?

Hi Tim,

Which company F3 did Dave use?

 

Kind regards,

Hiro

Hi Tim,

Which company F3 did Dave use?

 

In 1971 he raced the works Lotus 69, Hiro. You can find all the F3 results on Stefan Örnerdal's site, including this one, the Monaco F3 race which he won:

As you can see, many runners including Walker used Novamotor engines, and I assume they were all based on the Lotus T/C, but this needs to be confirmed.

I think you will find that most cars in the F3 restricted 1600cc period 1971-1973, finally with the 22.5mm restrictor, used engines based on the Lotus Ford twincam. Some used 3 main bearings rather than 5, most had fuel injection. With the restrictor the engines did not breathe so modest camshafts were adequate, as were standard crankshafts as 6000rpm was rarely exceeded. The choice of Nova, Vegantune, Holbay or AN Other were as much down to their ability to refresh engines quickly as anything else, Nova using a UK agent, whose name escapes me at present but it's in Autosport somewhere! Apropos of nothing particular I've a pic of my 1972 Ensign at Silverstone in April 1973 with 3 Holbays, one fitted and two lying on the floor!

Jimmy Fuller, who ran in 73 F3 with a BT38, had 3 TCs - a Novamotor, a Vegantune and a Holbay (all of which, with car, trailer and Transit went for £1000 at the end of that year) - and I'm not aware any one was significantly better than the others.
