Mxwrench:

I have had alot of novarossi engines and also the Recab and standard OS engines.

I have messured the timing on my first P5 that came out ( the engine that came with the large crank*) and the later one with the stuffed crank. I have meeured carnk timings and they are identilcal. The crankshaft with red putty has moore bottom end and slightly better fuelconsumption. I did not belive this and thought it was becaus it was two differetn engines. As a test i ran the first P5 engine and tuned for max performance. I took the engine out of the car and took out the crank and put in the crank with red paste. I was then convinced that it actually was the case. Crankshaft with red paste has moore bottom end and a little better fuel milage. It was moore difficult to drive and also i had moore wheelspinn out if the corner. Only thing changed was the crank, evything else was the same.

I friend of mine ( norwegian national winner) and best ranked Norwegian driver did run standard OS engines. I convinced him to try the Recab team version and he was in no doubt that the Recab engine had moore bottomend, better fuelconsuption and he also claimed it had higher top speed. Teh only difference between the standard OS and the Recab Team is lightend an red putty in the crank. Speed has actually been messured with a lazer gun under the Norwegian champs and a Norwegian cup race at the same treck under same conditions. Smae car, gearing fuel outside temp and so on. Recab made 3 km/h moore top speed.

If it is if the crankshaft is lighter or the red putty i do not know, but i support the thery that it makes a "pump effect" in the crank.

I now that the dyno should show it but i am not convinced that it is acurate enough for this.

Happy new year!!
