I did spring for the MM Intake. It helped a bit....mainly on the upper rpms. I also run the 84mm FM TB. Longtubes are just not worth it for the cost / payback as per all the evidence that I have seen.
No doubt the Wideband would be great to have. However....Jay has me dialed in pretty dang close. I was on a Dyno a while back and the A/F ratio was dead on 12.5, 12.6 across the band. I do not experiment with race fuels. With a mechanical compression ratio of 10.9 there is a point that the extra octane begins to hurt performance. Around 96 octane is all they need. I use Klotz Octane Booster when I race and you can really feel the difference it makes. I have done some data logging with the Klotz.....and Jay added a touch more fuel and another degree of timing. The power is there but my "thorn in the side" this whole time is traction. With my current setup I am closing in on some good times.
I STILL have not had a full hit yet. Been too damn skeerd! lol
I'm confident with good air / temps I am in the mid or better 11's.
I did the back seat delete kit.....saved 60 lbs there. I pull the passenger seat before the track...another 65+ lbs. I'm keeping the heavy battery....hell....I might tape some weight to it! lol
I would like to be able to do a bit myself. Is there a PID on the Trinity for a/f ratio? I would like to play with it with different brands of gas. All we have in the Country here is Shell and BP. I run Shell always but after your experience I'm inclined to push the timing limit if I can easily do it myself and try different gas.
There is NO WAY I'm giving up my Drivers seat!!! When I was a young man....possibly. At 56.....HECK NO!! lol
We are in the range where very few people on the street can handle us. There are tons of Hellcats, Z71 Camaros and such that run in the 12's because of improper setup. They have a lot more power. But "spinnin ain't winnin" as I can definitely attest to!
It's hard to argue with success. Dr. Carl you are my Hero for sure! Props to Ridgeback and Rob as well! (they bad) You got a good Hot Rod that lays down great #'s consistently. Too me....thats success
I can't see doing longtubes either. If I had a money tree in my backyard maybe, but sadly I don't.
A wideband is good to have regardless. Even basic modded cars running a solid email tune can be off. Every car is different, every atmosphere is different, and each batch of fuel you can is slightly different. More than likely you're in the ballpark, but there's always room for improvement. Once I got the wideband installed I found my car was running a tad lean. I told Jay and he richened up the tune a bit. Probably a 5-7hp difference if that, but still every bit helps. It's a good thing to have, but I understand your point of view as well.
I run 100-102 octane in my car, but I have more timing in the tune over the 93 tune I run on the street. I have it dialed in pretty good. I added 1 degree more at the track last year and the MPH stayed the same, so I backed it back out. No KR, just pulls hard. I like to run 1-2 points of octane over whatever the tune is setup for, just for a little cushion.
The Trinity can log A/F ratio, but you need a wideband. It requires an analog cable from your wideband to plug into the Trinity itself. I've set it up on my car and ran a few logs. But I generally just watch the gauge on the street, get it dialed in good, then I go run it. My first pass I check it and if it's somewhere between 12.0-12.5 I'm happy. The factory O2 sensors are narrowband only, 0-1V I believe, they just monitor and aim for 14.7:1. The wideband is 0-5V and can monitor 0-20:1 I believe. It's the additional O2 sensor that you need, not just a gauge.
Running mid 11's is nothing to sneeze at. I know I'm not the fastest Scat Pack out there, but there's usually not many faster 392 cars that are N/A whenever I go to the track. Most are running 11.8-12.3. All the little tricks help and add up. I'd love to have a Hellcat, but I'm not paying an extra $15-17K out of pocket after trading my car in and picking up a used Hellcat. I could do a lot of stuff with that $15K, to either my car, my Nova, my house, with the wife and kids, vacation, savings, etc. I never thought I could get the car to run as fast as it is currently. Back when I first got it low 12's was my goal, and 11.99 was a dream. Had no clue how much these cars were capable of. It's been a lot of fun racing it and learning things over the past few years.
Glad some of my tips have helped you! Good to see other guys going fast at the track and having fun too. Always fun to see the Ford and GM guys snickering at our "boats" only to see them run mid 11's with some minor mods haha!
