I dynotuned my jeep before the Setup.
I have seen a couple of guys putting down 82-82whp on this 2.5L (120bhp rated). All i have seen are Manuals, without A/C and 31s or stock tires.
I dynoed mine with A/C, automatic trans, and 33s Boggers and it put down 54whp. I guess I had a few death ponies, with heavier tires, and automatic (parasitic loss)..
after trying with a few different fuel management methods, It wasnt cutting it and I was running lean. I even tried adding an extra Fogger/injector.
I replaced my injectors with 850cc and injecting two times per 4cycle and the Haltech , the ponies started appearing while running rich rich.
at 6.67 psi I gained 71whp.
Now i am runing (at) 9 and gained like 15whp..
140whp... but with all my parasitic loss... the engine must be around 230-240. at most.. I dont think it touches nothing near 300hp.
well if that is all correct you just beat the laws of physics - my bet is that there was an error on your initial dyno run, you just can't make 140% more power by adding less than 50% air (atmospheric pressure is 14.7psi, you added 6.7psi which is 45% roughly, not to mention losses with adding a turbo so you would not be getting exactly 45% more power). more realistically maybe adding the Halltech fixed some of your initial fuel issues so if you would have re-dynoed without the turbo probably would be somewhere in the neighborhood of 80HP (30% loss in the powertrain let's say for the sake of argument) in which case the gain would be 45HP - still not there as far as numbers, it is more than what the numbers tell so there has to be some error somewhere
basically for you to gain 120HP total you'd need 14.7psi and that is not considering any losses (ideal and not real world scenario), for 9 psi you can do the math to get the propper percentage
the reason i said 300HP is considering 85HP gain at 9 psi at the wheels (taking 30% drivetrain loss) and using simple math
total_HP=(85*(14.7+9)/9)/0.7 = 319HP, and that again is without losses in an ideal scenario, very unlikely.
I'm sure you make way more power than before just the gains are not realistic, some parameters in one of those dyno pulls were off (maybe in both, not sure).
i checked your project on Jeepforum, looks good, interesting you had to get a new crank pickup - seems that the guy was trying to get the signal of the cam sensor which is 1 tick every couple of rotations and is not too precise either (it's only used to trigger the injector opening sequence) but I like the new pickup solution.
One other thing, reading thru your project posts seems that you run rich without boost and then you lean out when your boost goes up, should be the other way around though - one thing i noticed is that your injectors are 80lb/hr, that could be the reason your afr is way too rich at no boost and low to none throttle opening, the injectors are too large
check this link and give it a read
http://www.rceng.com/technical.aspxyour injectors should be somewhere around 40lb/hr, about half of what you have installed right now. The other thing is that with the current injectors you should def not be too lean in boost so that's anothe thing i would look into (tuning).
good job on putting it all together, keep us posted how it works.
