ZR8ED Posted October 28, 2005 Share Posted October 28, 2005 AND actually brings his own car. AND its a Z! AND its actually his good Z! (well at least his longest owned) Well I made it to my first dyno session with my VG30ET powered 1978 280Z. Some stats for those who don't know. stock VG30ET internals from a Jspec 1988-89 engine. Hybrid t3/t4 turbo Volvo i/c 3" ss downpipe and full exhaust. 60mm throttlebody 2.5" i/c pipes Turbo xs BOV and manual boost controler 370cc inj upgraded fuel pump adj fpr Modifed ecu. Well I didn't have time to upload pics yet, but I do have some numbers. We did 7 runs, with no adjustments. We were there to get some numbers, not to tune. The car goes into winter storage on Sunday. We only ran the car to 5000rpm on each run, because of uncertainies about air fuel ratios throughout the powerband. The power curve kept increasing at 5000rpm, so we were pretty sure It would climb a bit further. hp and torque came on strong by 2200rpm. The curves looked very good. I have some lean spots that need work. Lots of tuning to go.. The numbers acording to the dynojet 300 RWHP 351 ft/lbs of torque @5000rpm (best run) Not a bad way to end the season.

Guest JAMIE T Posted October 28, 2005 Share Posted October 28, 2005 They didn't have a wideband to hook it to for air/fuel readings? The shop that I used to use had one, but they charged extra to use it since it has consumable parts. Of course, I never paid for any dyno time even with the wideband.

slownrusty Posted October 28, 2005 Share Posted October 28, 2005 Great numbers! Are you going to reprogram your ECU or up the fuel pressure to address your lean issues? Yasin Quote Link to comment Share on other sites More sharing options...
Bernardd Posted October 28, 2005 Share Posted October 28, 2005 Can you post the sheet with the afr's? Quote Link to comment Share on other sites More sharing options...
J Taylor Posted October 28, 2005 Share Posted October 28, 2005 Not a bad number at all for the limitied modifications. Nice. JT Quote Link to comment Share on other sites More sharing options...
ZR8ED Posted October 31, 2005 Author Share Posted October 31, 2005 Sorry but the graph looks a bit crappy. I photocopied the original and I needed to darken the lines with a pen so it would show up better. I do not have the af graphs in my possession. I'll have to see if the mechanic has them. They had lots of trouble with the graphs with the a/f. the graphs I do have of them, they are scaled too small to really get a good idea of what was going on during the run. More to come.
