Element Tuning Time Attack STi 2 From a 148 MPH Crash To A New Track Record. Video
Just as we started to get the new car and myself sorted out our season is over but the new STi is performing better than we could have ever imagined.
New graphics from Speedesign look great. We wanted to do something new and different but keep that mean look the car had in all black. We couldn't finish completely as the vinyl wouldn't stick to the unfinished bumpers so we need to get those painted before the whole look is put together. Rota DPT from WheelDude.com in 18x10 Matte Black hold the Hoosier 285s on very nicely! New Sparco Circuit Pro Seats, Belts, and Steering wheel from OG Racing and Sparco USA keeping me safe. One of the single largest and most critical improvements on the car is the Fulcrum Aero wing. Jim went above and beyond building us a reinforced with with improved double lap joint mounts. Notice the heim joints for reduced stress on the mounts. The wing is also very easy to adjust because of this mount. The final race of the NASA Mid Atlantic Championships was this past weekend at Summit Point Raceway. We updated our Element Tuning custom BC ER Series Coilovers with new valving and Swift Springs to increase front roll stiffness on the car in attempt to settle the rear end down under acceleration. We tested this at VIR warming up and ran a 1:59 which would have been good enough for 4th in the UTTC race so things were looking good. On day one we set FTD breaking the old TTU lap record of 1:16.07 with a 1:15.4 lap but the cold track made it tough to get the heat I needed in my Hoosiers. On day two we tweaked the Fulcrum rear wing for about +45 lbs more downforce with only a 6 hp penalty in drag, dropped tire pressure on the driver's side, and we adjusted the front and rear clickers on the BC coilovers. With the track temp coming up we were able to set a new TTU track record at 1:14.439! Enjoy the video, From a 148 MPH Crash To A New Track Record: YouTube: Pre Rebuild: Starting the new Time Attack season we wanted to freshen up the engine and test a few new parts. We started out rebuilding an Element Tuning Pro Comp engine but we switch up the bearings and the compression ratio of the pistons to see how they hold up over a season of racing. Numbers Dyno: Dynojet Altered Atmosphere Gaithersburg, MD Tuner: Phil Grabow Element Tuning Wheel HP: 570whp UNCORRECTED Wheel TQ: 492wtq UNCORRECTED Baseline: 185 whp 08 WRX Target Boost: 27 PSI Target AFR: 11.8 AFR Fuel: Sunoco 110 Octane with Hydramist (80% water) Ambient Temp: 50 Elevation: 0 With a new engine I really didn't want to run it too hard on the dyno so I stopped at 27 psi. I made quick work of the tuning with the Hydra 2.6 software and had all tweaked in as few WOT pulls as possible. In my previous dyno sessions the 1000cc fuel injectors were maxed out so this time around I bumped up the fuel pressure to 55 psi giving me about +20 more flow so I could have a little safety margin on the injector duty cycle. Maximum fuel injector duty cycle was 83% with the 1000cc, A1000 fuel pump, and 55 idle fuel pressure. I totally forgot that I didn't like the billet compressor wheel I ran late last year which netted me about 30 whp loss over our standard GT65 wheel (GT35R). With the higher compression and the BC STG 4 cams it looks like we gained back that loss however. The numbers are good for this dyno so I'm happy for now with the improvement. Car Info Year: 2006 Engine Management: Element Tuning Hydra EMS 2.6 Turbo: Element GT65 (testing new wheel) Intercooler: Custom Meth Kit: Hydramist 80/20 water/methanol Injectors: UR 1000cc, Element Tuning Competition Surge Tan, Aeromotive A1000 Engine: Element Tuning Pro Comp: ET Rods, Manley 9.8:1 Pistons (custom ring pack), ET Big Valve Heads +1mm valves, BC STG4 cams, stock block and bore. Intake Manifold: Subaru RS Headers: Element Uppipe: Element Tuning GT65 Downpipe: Element Tuning CBE: Element Tuning Other: Element Tuning Competition Catch Can The BC ST4 cams required me to work on the AVCS mapping as compared to the Cosworth cams. I found that I had to carry the advance farther into the RPM range but in the end the Hydra EMS allowed me to get it exactly how I wanted it. Having made some new changes to the car I wasn't sure what the car would weigh in at so I had to have options available for HP so that I could stay in NASA TTU classification. At about 15.3 psi the car made 452 whp which should be low enough to keep me legal in that class. With the new engine tuned we headed off to the second round of the NASA season at Virginia International Raceway. One of the major changes we made to the chassis was to have taller wing supports made so we could get the rear APR wing up into clean air in hopes of gaining down force. We also had added a rear diffuser to the flat panel underneath the car. After running at minimum power for practice and scrubbing in new tires the car felt great and the power delivery was awesome. As we headed out for time session one disaster struck on the first lap! I was taking it easy to get the tires up to temperature but as I exited turn 6-7 the carbon wing structurally failed between the air foil and the mount. Not knowing this I entered the uphill esses at around 148 mph and this is what happened. YouTube: Thanks, Phil Grabow Element Tuning

Awesome numbers on the tune.
But so sorry to see what the result was. Glad you're okay. Hate to ask so early but what's the planned next step? Newer shell or a lighter shell? |

When the wing broke off I had way too much front downforce and no rear downforce and as I clipped the inside curbing on the left it just went up and around. |

Still can't believe you only suffered a bruised arm from this. Glad you're okay and already picked up that shell.

Glad to see you weren't hurt bad phil! That was just nuts how it happened, at least you didn't roll 40 times.
Just goes to show how much wings really do for aero and keeping things to the pavement. |

I am sure you always have someone else tighten your harness for you! hope your wrists come out okay in the next weeks. that was a hard hit to break the steering wheel.
time to look at a better wing solution? is there one? |
