At last, after running in my new 1911 Engine I have now tested the performance of the double D-jet arrangement VS single stock D-jet:
Acceleration on plain road from 37 to 68mph in 4th gear was one second faster with the double arrangement (10 VS 11 seconds). Tested several times on the same road with both systems, no wind etc. My double system has an extra fuel enrichment at 3/4 throttle (by fooling the cylinder head temp sensor), my stock not. Looks like Im removing the double arrangement due to the minor advance... (IMG:style_emoticons/default/sad.gif) also it is blocking access to #3 spark plug... /Lars S (IMG:http://www.914world.com/bbs2/uploads_offsite/www.lsmteknik.se-10787-1389339349.1.jpg) |
