Haven't done any real world tests lately. So used the weekend away as an opportunity to prove, if things are done correctly in the engine build and tuning department, old classics can show modern cars a few things.
We used Hedleys Sprite as the mule..It has a 1275 A series with a mild Miniformance cam, and head porting. A 45 DCOE for carburetor and a Mazda 5 speed gearbox. Cruising at a safe 115kmh GPS true speed down to the Berg and back. Down was on the N3 to Harrismith, and into the berg, via Sterkfontein dam and Berville, back we did the trip via Clarens, Reitz, Heilbron.
So a nice mix of hway, and B roads, with varying traffic conditions.
I was blown away with the consumption, averaging of 6.1 l/100km. For the 900km round trip
Easy to overtake in 5th gear, plenty of punch. The Sprite was loaded with gear.
Very pleased with the outcome
Happy customer..
