markrolston@mac.com Posted November 8, 2014 Author Share Posted November 8, 2014 (edited) It has been a very slow fall. I started a new company and that's eating all my time. Nevertheless, there is some progress to report. The car is getting seriously close to finish. I am tentatively going to drive it in a race on December 13th. At least that's the deadline I gave myself. It would not be painted in time but at least mechanically race-ready. Here are some recent pics of progress: intake piping for the turbos aluminum tray under the motor for aero and protection of transmission heat shields for the turbos firewall heat shielding Edited November 8, 2014 by markrolston@mac.com Quote Link to comment Share on other sites More sharing options...
EF Ian Posted November 8, 2014 Share Posted November 8, 2014 Will be great to see this beat running, make sure to take videos when it happens. Good luck with getting it finished in time. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted February 27, 2015 Share Posted February 27, 2015 So it's February almost march... Did you get to race? Quote Link to comment Share on other sites More sharing options...
Turbo6.0 Posted March 2, 2015 Share Posted March 2, 2015 (edited) Awesome build! The links on the first post don't seem to be working for me though. Is there anywhere can I see the earlier pictures of the build? Edit: Nevermind, figured it out... Edited March 2, 2015 by Turbo6.0 Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted March 7, 2015 Author Share Posted March 7, 2015 Obviously things have been very slow. I did not get to race it. But it's running and will get tuned this next week. And we finally have some decent progress on the rear diffuser. It hasn't been trimmed so the pics you see show it hanging far lower than the final part.

skyline34 Posted March 25, 2015 Share Posted March 25, 2015 Been following the build for a while... Knew your name, but just made the connection. Wouldn't expect anything less! Keep up the great work on the car and with Argo! Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted April 2, 2015 Author Share Posted April 2, 2015 The diffuser has turned out to be quite a complex project. But it's all glued together now and we're going to trim it to shape. I spent some time this week trying to decide what line to cut. Also, we're scheduled to put the car on the dyno friday at UpRev to do a first tune. Quote Link to comment Share on other sites More sharing options...
Sovereign Z Posted April 4, 2015 Share Posted April 4, 2015 (edited) How did the dyno session go? Edited April 4, 2015 by Sovereign Z Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted April 21, 2015 Author Share Posted April 21, 2015 After a week or so of delay getting the dyno booked, we put the car on the dyno today and found a handful of technical issues so we didn't really get it tuned yet. More to come... Quote Link to comment Share on other sites More sharing options...
ihiryu Posted May 5, 2015 Share Posted May 5, 2015 I still want to come and see this beast, so it can make me regret selling mine. Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted May 6, 2015 Author Share Posted May 6, 2015 Ok, so after the attempted dyne turning session, we pulled the motor and inspected it. Why? during the first few pulls, we noticed an odd clacking sound. So it appears that one of the bearings is bad. We don't think we did any serious damage and now we're sending the motor off to a very trusted builder to fix it and do a bench dyno to ensure everything is good. We did the original build ourselves and in not-so-perfect conditions. The parts are right but it's obvious we missed something. On other fronts, the rear diffuser is nearly done (I posted some pictures here) and we're now working on fixing the catch-seams for the front hood. Right now we have a small lip built into the carbon but it takes too much effort to line up the hood. The new design should help the hood find it's way into a perfect fit when it's closed.

EF Ian Posted May 7, 2015 Share Posted May 7, 2015 That's some diffuser. At least no harm was done to the engine and it will soon be up and running 100%, look forward to seeing it go. Quote Link to comment Share on other sites More sharing options...

markrolston@mac.com Posted December 14, 2015 Author Share Posted December 14, 2015 sorry for the long absence. We've made progress but it has been slow. I've been holding out for a big update but it keeps dragging out. Hopefully later this week.... We've been trying to tune the engine for a couple of weeks but have run into various problems, most recently a case where the boost plumbing was not allowing the MAF sensors to get a good reading. We are going to try fitting some larger diameter pipes. In the meantime, here's a few pics from the last few weeks: shown here: detail shot of intake plumbing, rear diffuser fitting work, progress on side door sills, and the car sitting on the dyno this week getting what hopefully will be it's first full tune.

markrolston@mac.com Posted December 18, 2015 Author Share Posted December 18, 2015 We fabricated larger diameter charge pipes to improve the range of the MAF sensors. It appears to be a typical issue with boosted VQs. Now back to tuning. Quote Link to comment Share on other sites More sharing options...
EF Ian Posted December 20, 2015 Share Posted December 20, 2015 Thanks for the update. Would it not be easier to run it MAFless? Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted February 26, 2016 Author Share Posted February 26, 2016 no update for some time because we're running into a mysterious issue with the variable cam timing control. L/R cams not acting in sync and we can't figure it out. A lot of this is simply related to the fact that we're still using the stock ECU yet we've otherwise made a lot of changes to the motor. It's been slow but we feel close to working it out. In the meantime we're also trying to finish up the last bit of carbon work. From there the car will be ready to drive and get painted.

ihiryu Posted March 6, 2016 Share Posted March 6, 2016 Agreed, I don't see why you don't go standalone. I could get you a megasquirt or ECUMasters for a great price if you're willing to try it out. Megasquirt just updated their software to support the VQ trigger wheel. Quote Link to comment Share on other sites More sharing options...
markrolston@mac.com Posted March 8, 2016 Author Share Posted March 8, 2016 I appreciate the advice from everyone to use a custom ECU. I have a Motec M6 in my RB26 Z (http://www.rolston.me/NewSite/Z-Blog/Z-Blog.html) and while it's arguably one of the best aftermarket ECU's, even the best programming can't match what the factory ECU can do for basic drivability. Any custom map likely suffers from cold-start, decel, part-throttle, and other tune weaknesses. I'm determined to start with the factory ECU along with the UpRev programming to see if I can have my cake and eat it too- meaning to have a nice drivable map along with the high power setup that I've built. So, on to the latest update. We fixed the issue and have now worked through our first test tune. It did 430WHP on spring pressure and a very conservative map. The setup will accommodate several hundred more WHP so we will continue to refine the tune. The schedule target is now to have the car finished and running for the Nismo Fiesta in San Antonio at the end of April. It may not be painted but I expect it will be finished otherwise. Then we can do a few months of test/tune at Harris Hill to figure out what spring rates, shock settings, etc. work best. If you recall, the entire frame and suspension of this thing is custom and therefore we have no real idea of what will work best. at it's current weight of less than 2000lbs it should be quick in any case.
