OKI see a fuel pump,log and injectors...It's a direct port injector set up?
Some of the busa drag guys make 800 HP
If it weren't for the pesky FMU life could be good.LOL!! Of all the things about a t'bo install the FMU is the PITA no doubt.
Hey all, newbi here but been to all those other sites. Masterfabr hooked me up here so I wanted to come chat. I have the Hahn system on my little busa car. I know there are skeptics out there.... and I am sure there are better systems out there. But for me, this system works great. Simple and effective. I would tend to agree that the weakest link is the computer/programmer. But, as long as you adjust for the flaws it works out well. I spent quite a bit of time with mine on the dyno. The only thing that kinds of sucks is you can only adjust the fuel curve in 1000 rpm increments. Don't get me wrong though. You can still get a pretty flat A/F line on the chart. I have mine set up and it stays between 11.4 and 11.8 A/f from low boost all the way to 26 #'s Might be able to get it tighter but why? It is safe, runs awesome, and I am not running a bracket drag car here so perfection is not really needed. But a little more time on the dyno and I am sure I could get it even tighter. Its just those 450 + HP pulls scare the crap out of me!! My map I am sure is quite a bit different. I am not using and intercooler and above 12 lbs of boost I use water/methonal injection. Yes, I leaned the map for the methonal, risky if you run out... yes, more power... yes I'll take the risk. I run a two stage boost controller so that when duning I keep it under 12 lbs. Flip the switch and I have 26 lbs of boost, timing retard and methonal injection both above 12 lbs. I can also say the the boost transistion is awesome over a fmu. My car is so much smoother that it feels like it is making less power on low boost but in reality its about 60 hp more on low boost. Just so smooth it feels like less. So Enemy, I think you will love it. Hit me up if you have any questions. Pretty simple install though.
Very much agreed.. Sometimes I think the little shit attributed to my liver damage and disappearing brain cells...
THAT was the RMU(rum management unit)effing up!
