2015 3.6L VVT V6 mod option help
Morning everyone. Looking for some advice / direction. The '15's VVT puts out 323 at the crank and I want to boost that up a bit more with out dropping thousands on forced induction. I've already installed CAI's cold air intake and Borla's axel back Attack SS exhaust. On paper (have not dyno'd) that's about 343 and putting down the track 14.523 sec @ 96.735mph. I've been reading a few very old posts about tuners for the '12 but nothing on the newer. The plug and play options I've found very greatly between +10 - +30hp which sounds suspicious. Untilately id like to get it up to about 360hp.... thoughts? Thanks in advance.

If you're getting ~280 HP at the wheels with intake/exhaust/tune (no E85) wouldn't you already be at ~360 HP? A typical auto LFX gets ~250 HP to the wheels which is a ~22% power loss (250/323), so assuming the same losses 280 HP at the wheels = ~360 HP at the crank, or do the bolt-ons and tune actually reduce losses? If you'd in fact be getting less than 360 HP then I'm still telling everyone I'm getting 360 because that equates to 100/liter which is a nice, round number

Updated mods....
Cold Air Intake (Aero Dynamics) VMAX CNC Ported throttle body Helix Throttle Body Spacer JacFab Air Intake Manifold Spacer Jet Perfomance Stage 2 Module Jet Performance Mass Air Flow SLP Loudmouth Axle Back 1 Elite Oil Catch Can Struts/shocks Vitesse Throttle Controller Air/Fuel Ratio Guage Boost Gauge Zex Nitrous (pending installation) Now, Overkill has a tune that claims removal of speed restrictions. Also claims gains of 15-30HP on 91 octane. Has anyone used this tune before? Last edited by bonecrusher5150; 01-01-2017 at 07:44 AM. |

Thanks Kenny. Thats exactly what the site mentions. 91 Octane with an overkill tune is not as good as E85 with the tune?
does anyone have hard data on it? Just curious. |

I don't think you will find anyone more dedicated to improving the performance of the LFX and LLT engine. Will at Overkill is great to work with and his product has been proved that. I've had the Overkill tune, 80mm tb and e85 upgrade for close to a year now and it's combination is awesome. I'm putting together a supercharger kit and Will has helped with that as well. I don't think there is any other tune out there that can beat Wills, even dyno tunes are only equal to it at best.

Yes, that's correct. I don't have the hard data on hand, but I can relay a representative account of the results. Different levels of modification will bring different end results. These numbers are just kind of an average of results I've seen over the last six months or so of reports with the Overkill tune with Overkill products. These results reflect nearly a full bolt on modification with the Overkill tune. Automatic trans with 91 octane, 280 to 285 rear wheel horsepower. Auto with E-85, 302 rear wheel horsepower. Manual transmission on 91 octane, 289 to 294 rear wheel horsepower. Manual on E-85, 316 rear wheel horsepower. Remember that all dyno's are different and weather conditions effect the results they obtain. The E-85 numbers are the highest numbers I've seen in normally aspirated LFX reports.

Wasn't that a third gear pull? That's what DJ's spread sheet says, third gear pull. They usually read a bit higher than a fourth gear pull, don't they?

Average on an auto stock is around 255, Manual has less data but should be around 270. Sycraft is an outlier haha 323*0.15 = 48.45 323-49 = 274 323*0.20 = 64.6 323-65 = 258 So the data supports the rough calculations.
