I was told I need to post this over here so you guys could see what I did with my this last week. It still has the junkyard LMM Ambulance motor in it with my 68mm Stg2R on it. Well, since Dave Burton went to the track and ran an 11.58 with the new 10mm CP3 and we redyno tuned it, and Kyle Harbin pointed out that it was faster than he or I have been with a stock motor the challenge was presented to see if I could match him or beat his time. So I grabbed my Exergy 250%inj and 12mm CP3 off my built motor and put them in the stock motor and retuned it for them. Made 749hp 13xxftlbs and went to a track and ran some 7.xx at 97mph in the 1/8th with shitty traction issues. Got to thinking about it and decided to get really technical with it and put it back on the chassis dyno with my cylinder pressure tool to see what, when and where it was making power. The goal was to make as much power as possible with the setup without destroying the motor. Thanks to Fingers I had my stock rod limit threshold and used it as my guild and tuned around it til I stopped picking up power. I ended up at 780hp with a much flatter power curve while keeping the cylinder pressure in check! Feeling a lot better about the setup now we headed to Byron to see how fast it would go. First pass out on a soft launch she went [email protected]! I was extremely pleased with this and decided to see if I could get it to go faster! I went back and pulled the passenger seat and center console and all the lose crap in the cab including my stereo amp and sub thinking I would pick up another tenth hopefully. Well, it backfired in my face because the track went away for us 2wd guys. Tried to leave harder and the 60ft times got worse but I managed 120mph on the next pass but it was only 11.35. Final pass I get to line up with Brett heads up and was to busy watching him leave me sitting there and I forgot to shift so I went 11.78@119mph. Well I ended up Runner-up in the event and got a trophy for it so had a blast! Nothing broke and motor is still as strong as it was when I started! To verify this I used the cylinder pressure setup to measure cranking compression before I started the tuning session and after and now and it is still at the 480psi it was when I started. I am very happy with the results to say least. Tuning the engine via cylinder pressure is the only way to truly know what is happening in the motor. This is the first time I have utilized this tune on my chassis dyno as it was purchased and has only been used on my engine dyno for the big stuff but I will be implementing it a lot more in the future. Hope you guys enjoy this as much as I did!
