So today was chance to get some 1/4 mile times. Best ET was 15.9.
From this i can say that about 120kw is from engine. Car stock emty weight should be 1180kg. I took out spare wheel,and rear seats. Maybe -20kg. 1160kg + me 110kg + about 25kg fuel is 1295. Lets say 1300kg. We have in one estonian usa cars site very good ET times calculator,and from this i can say that approximately 105kw from wheels. And its about 120 from crank.
Now its time to think on standalone. Chip isnt worth the money. And its not so accurate also.
Next goal is 14.9 ET For this i need 130kw from wheels theoreticaly. About 145-150kw from crank. Not so easy
Edit: Trap speed was almost 142kmh , 1) car is lighter than i think 2) there is more power from engine. Calculating shows about 125-130kw from engine with this quarter mile trap speed.
Some day must weight the car.
