We took a friend of mines 98 GSX to the dyno this morning. His car has been getting further and further away from running well. Brandon and I have tweaked it over the past few weeks to get it ready for a full on tune. I tried very hard to get him to do an E85 blend. But basically he is too lazy to go the 10 minutes to get gas fromn the same station. Too much of a hastle to go to the same place I guess.
Well, after a few small wiring issues this week I did a preliminary tune the other night. To get it back. He was still having boost controller issues, so we let him use the one off the Mirage. Finally fixed that problem. Or so we thought. We got to the dyno and everything was going well. But, it would creep and was spooling very slow. Then we just hit a wall and the boost would not go up. They still had the boost controller setup to run like the Greddy electronic boost controller.
Joe F. called in the middle of a run, so I let Josh and Brandon tackle the vacuum line swap while the car cooled down. They eliminated a few T's and took out like 3 feet of tubing. Well needless to say, we fixed the problem. Maxed out the 35psi boost gauge in a hurry. Took about 5 or 6 full turns to get back to reasonable levels.
Final result was a safe and clean tune. Enough to where the car can be hot lapped with ease. Air/fuel ratios extremely stable at 11:1. A torque curve that looked like a table top. Spool up that was unreal, and got most of the driveability setup down low.
24psi netted
329.59hp 312.48tq uncorrected
410.05hp 388.77 corrected
Full boost by 4200rpm on the 2.0L. She is a torque monster for sure now. We could have gone for 26-27 psi, but I would have had to fudge the timing and fuel just to run big boost. I felt this was good enough that he can hand out some ass whoopings when ever he sees fit. Great car Meho. Hope you enjoy it. Just let us know when you are ready to play with E85 or 110+ octane.
12 second time slips here we come.
