510T Posted June 13, 2013 Report Share Posted June 13, 2013 Looks like a whole lot of fun :) What kind of speeds were you hitting? Quote Link to comment
Uber Deaf One Posted June 14, 2013 Author Report Share Posted June 14, 2013 110-115ish into turn 1 is my best guess. I never actually looked at the speedometer except once through turn 2 because it's sooooooo long lol. Approximately 70 mph all the way through turn 2. Quote Link to comment
Uber Deaf One Posted August 21, 2013 Author Report Share Posted August 21, 2013 Got some rolling pics/vids of the 510 today, will prob be taking a lot more over the next couple weeks. Pics were taken with a Samsung Galaxy S3, vids taken with a GoPro 1. Quote Link to comment
Uber Deaf One Posted October 10, 2013 Author Report Share Posted October 10, 2013 Some updates... Finally switched over to rear discs, and installed a rear panel/speaker hole cover. We should have done that sooner... the fuel pump noise was driving us nuts! '86 Maxima rear calipers Caliper rebuild kit New brake hardware Stock pads, Centric brand '82 200SX rotors, Centric brand '96 Quest rear wheel studs Custom brackets Total budget build but it works great. This setup goes well with the 280ZX front brakes and 15/16" Master cylinder. Carbotech can make race pads for these. Probably pricey like the 280zx track pads I got from them, but they'll last quite some time on a car this light. The rotors are 9 lbs each... pretty thick too. Little heavy... but eh, fine for the street. Later when the car is more track oriented we'll design a set of light 2 piece rotors or something. Quote Link to comment
Uber Deaf One Posted November 19, 2013 Author Report Share Posted November 19, 2013 Suspension is dialed in, brakes are done, car has 4 fresh tires.... and there's an AutoX event this weekend. Now to see what this car is really capable of... :D Also planning on running at Laguna Seca at the end of January. Quote Link to comment

Uber Deaf One Posted November 24, 2013 Author Report Share Posted November 24, 2013 AutoX today went well. Didn't get to play with the new rear brake setup much, but finally got the rear spring rate where it needs to be. First run group of the day, and it was a real cold morning. It started to warm up throughout my run group, each run I had more grip than the last. Real happy with the performance of these 300 tread wear Dunlops :D Quote Link to comment

Uber Deaf One Posted December 10, 2013 Author Report Share Posted December 10, 2013 Dynoing the 510 and my dad's Mazdaspeed 3 at Z Car Garage on Thursday :D Will have pics and vids of both cars, of course. Quote Link to comment

Uber Deaf One Posted December 28, 2013 Author Report Share Posted December 28, 2013 The Mazdaspeed 3 dyno'ed at 280/301 to the wheels. The 510 had some issues running way lean up top... we've spent the last couple weeks going through everything and we've fixed quite a bit. The TPS and coolant temp sensor circuits share a ground, and with the key on the ground wasn't sufficient. Seeing as the TPS and coolant temp sensor largely affect how the engine runs, I think we fixed a pretty serious issue just right there. Got a Walbro 255lph in there now too. It's still going lean up top but nowhere near as bad... stays rich down low til 3400 rpm then leans out. AFR is 14.0-14.4 at 6k rpm. I guess all these mods and gasket matching is too much for the stock tune. Time for Nistune yo. Lesson learned... even if your shit seems to run good, there could still be something wrong. Check your grounds! 510 will be back on the dyno sometime in January. http://www.youtube.com/watch?v=1Ox9d9niAYQ http://www.youtube.com/watch?v=EolJG8q4tY8 Quote Link to comment
Uber Deaf One Posted January 5, 2014 Author Report Share Posted January 5, 2014 Ordered an adjustable fuel pressure regulator and got that installed yesterday. Doin what we can to fix the lean condition at high rpm. Right now the fuel pressure is at ~55psi, AFR is 13.8 at idle and 13.2 at WOT. Cruising, the o2 sensor does its job and controls AFR just fine. Now to get this thing back on the dyno... Laguna Seca in 3 weeks. ;D Track pads for the Maxima calipers will be here this week. Quote Link to comment

Cpl620 Posted January 6, 2014 Report Share Posted January 6, 2014 YEAH! updates! love this thing, whats the next plans for it? or are you calling it done? Quote Link to comment
Uber Deaf One Posted January 12, 2014 Author Report Share Posted January 12, 2014 I'm done putting money into this thing for a while, just need to finish up the interior. Another seat, harness, sound deadener and carpet... Prob will get another set of wheels and tires for track only use soon as well. Then I'll call it good. Later down the road... r180 lsd with custom cv axles, along with a turbo build. At this time we'll be pulling the engine and tearing it down to tap the oil pan... while there it's getting a windage tray, crank scraper and new lower timing cover/oil pump. I've been running Amsoil for a while... love this stuff! Laguna Seca in 13 days.... hurry up already. Track pads are going on next weekend. Carbotech's 280ZX pads stopped the car pretty damn well in 117 degree weather with stock drums, I can't wait to see what it's like with 4 wheel disc and good pads. Quote Link to comment
