Well today was????
Interesting.
We still have some minor issues with the steering wandering. Time to buy a recon steering rack I reckon and get the tracking done properly Smile
first run off gas was just to blow the cobwebs out. She is running really rich and struggles to rev over 5000rpm due to bogging. This is why she would only pull a 14.3 last week. We had no time to rebuild the carb an faff around with getting the metering spot on. I know another way of leaning the mix out without touchng the carb??
I stuck a quick nitrous kit on yesterday. Finished the intallation in the pits this morning and did a static test. Intead of 50/50 fuel to nitrous ratio I had to go 25hp fuel to 70hp of nitrous. Lots of reasons for this which I wont bore you with.
Long story short.
1st pass 15 seconds on carb only.
2nd pass 12.9 seconds with a 70 shot of gas but still running rich.
3rd pass, I added another 30hp of nitrous to lean the mix out some more. This seemed to hit a sweet spot because the power delivery was pretty hard and caused the run to be aborted (see video) so Jay could get back to the pits and take a tea break to calm down
4th pass we dropped rear tyres to 11 psi and did a good smoky burnout. This time she hooked up and went pretty hard all the way to the finish to reel in a 12.3 second pass at 105mph.
OK!
I promised him a 13 second pass and we got close to pulling an 11. And an 11 second pass would have been very easy today. But not on the loose steering and bad tracking. So I told Jay we were calling it a day and going home in one piece which he was more than happy to do after experiencing his first tank slapper on the Drag Strip
