Took my newly B&G tuned 392 to the track
I installed my B&G tuned ECU in my Challenger this week. I reported my first impressions in another thread. I was real happy with the new feel of the car, but lets face it, butt dyno's lead to putting ones foot in ones mouth and the track was where I needed to go. Last year I made several runs at Empire Dragway. A member asked in my "first impressions thread what my best run was and although I didn't keep last years slips (due to major disappointment) I remembered rounding up it was 13.3@110. Today I was able to locate an email I had sent to a friend that night and it was specifically firstname.lastname@example.org with my seasons best 60' time of 2.165. MY freind (Heminator) also races there and he can vouch for how my car ran as he was running generally the same with his IE. To be fair, the tune is not the only new goody going to the track this year. I also added a Hopnot kit and replaced my K&N filtered stock airbox with a Airaid CAI. But, Heminator did the same and our cars have the exact same mods. He was at Empire a week ago and the Hopnot kit and CAI gave him a small improvement, he ran a 13.21 best. DA at the track was +2560 when I arrived and went down to +2230 by the time I left. My first pass resulted in me missing 3rd gear (I recovered quickly) and the end result was a 13.38@108. My second pass I tried coming out at 3600 RPM and flooring it which gave me a large amount of wheel spin (but no hop) resulted in a email@example.com with a 2.187 60ft. time. See attached slip, car #41. Third pass I decided to try the launch technique that I used last year on my best run. Do a burnout to clean the tread and leave the line at 2200 RPM, let the car bog and go. This yielded a firstname.lastname@example.org with a 1.961 60ft time. I knew then I was on to something as far as launch technique. On my final run, I brought the launch rpm up to 2300 RPM and this resulted in the nights best email@example.com with a 60ft time of 1.932. See attached time slip. After that, my friend with a Boss 302 traded cars with me for a couple runs and it was time to go home. There are some who might suggest that the improvement in the 60ft time was from the Hopnot kit but I would refute that. The technique that gave me my best 60ft was the bog and go technique which also gave me my best 60ft last year with no wheel hop. I only had severe wheel hop coming out hard. To be fair to hopnot, it is a great product and I can now do great burnouts with little or no hop. With drag radials, which would allow a hard launch, the hopnot would really shine. However the difference is that with the stock tune the motor bogs and before it takes off there is a noticeable lag. With the B&G tune with the TQ management removed, it bogs, but the car instantly squats and goes far quicker than with the stock tune. After that I also noticed that the bit of lag after shifts before the motor is back on full boil is gone. Empire is a sticky track and I have never barked the tires shifting into third gear on that track with a stock tune. Tonight, except for the missed shift run it barked the tires in third every time. I am going to up the launch speed up to 2400 rpm next time, because I think there is more to be had here. A couple other disadvantages is the bad air customary for that track and the fact that I am 6'4" 292lbs in a car that already too heavy. In conclusion, RB felt that 1/4 mile runs should easily improve 4 tenths with the tune. I think he hit the nail right on the head. Needless to say, I am very pleased with the results I got. Sorry for the crappy iPhone pics.
