    So... Ive been sitting here thinking, and I wanted to share one of the quickest and easiest ways to improve your 60' when drag racing. Its a pretty simple concept, and Definitely a DIY. hah. So here it is, One of the biggest drag racing mistakes people make right off the bat, is as simple as where they "Stage" their car. Staging, as in the two top yellow bulbs is the easiest and simplest way to improve your 60' and even as much as improving your top end mph. Staging is a series of 3 beams, pre stage, stage and guard beam. the guard beam is essentially usless to us as that is just to ensure your car isn't too low, or that you are trying to falsly trigger the top end beam. So the first beam, the prestage beam, when staging your car you want to take your time. typically I turn my top bulb on and let my fellow opponent do the same thing (Courtesy Staging) once both top bulbs on, my staging routine is fairly simple, and I do the same thing EVERYTIME. once both our cars are in the first beam I get on the converter on my car and SLOWLY bump the breaks so that I move less then an inch each bump, and I continue to do so @ 2000 rpms until the 2nd bulb (stage) is on, which is typically 7" at most tracks. and then get on my converter even harder, typically 2500-2800. But heres the catch... All of you people that blindly roll into the 2nd (stage) bulb have no idea where you are actually staging. In a perfect world you want to BARELY turn that 2nd bulb on therefore giving you 7" more of usable track, people may ask, "Why do I want to make the track longer?" and your answer is as simple as this... Your timer DOES not start until BOTH beams are fully connected again, meaning that your E.T. does not start ticking until you have moved approximately 7" So by this "shallow stage" method you will actually see higher mph, and lower 60' Your reaction time as well is recorded as soon as you technically recreate the beam, from the time the light turned green. in a perfect world you want to leave as soon as you see the last yellow light come on. I have been bracket racing for a number of years, and ill take my Camaro for example, that car does not react worth a damn. So typically I do my stage routine, but then give it 3 extra "bumps" decreasing the 7" to idealistically 4" which in return will improve my reaction time, but those 3 bumps cause my 60' to go from a 1.70 (when I shallow stage) to a 1.78 (deeper staging) and the overall E.T. will typically drop from a 11.85 @ 115mph (shallow stage) to a 11.98-12.00 @ 113.8 with a 1.78 (deeper stage) 60' You can even go as far as turning the top bulb completely off, which just means that the original "prestage" beam is back intact and your front tire is only breaking the stage beam. And I know a lot of you out there are thinking, this guy is full of shit, I dare you to try it next time you are at the track, try BARELY turning on the 2nd bulb one pass, and then the following pass deep stage and turn the top bulb completely off, I would bet you lose close to 2 tenths (.2) off of your total e.t. and at least 1-2 mph, provided you did everything the same as the pass before. I hope this helps someone!

    Koenigsegg seems to be taking issue with being omitted from supercar comparisons including the Ferrari LaFerrari, Porsche 918 Spyder, and McLaren P1. It is not that they are being specifically omitted due to politics or something nefarious. Koenigsegg simply does not belong in the comparison. Why? Because the trio of modern supercars referred to as the 'holy trinity' is on a level of engineering beyond what Koenigsegg does. Ferrari, Porsche, and McLaren actually have experience racing hybrid powertrains. They incorporated that hybrid technology into street legal supercars that point toward the future of high end automotive performance. Koenigsegg is living in the past. Their car may accelerate quicker but so what? There are Nissan GTR's that accelerate quicker than anything Koenigsegg produces. That is not the measure of a supercar. As much as performance is a factor as is the design and engineering. Their car is a dinosaur. A very fast dinosaur but it is nowhere near the level of technological accomplishment as the trio of modern hybrid supercars. Koenigsegg has not proven they are on that level. Continuing to increase the boost on a modular Ford V8 design they have modified requires nowhere near the engineering expertise as creating a ground up lightweight hybrid drivetrain designed for maximum performance and to provide the fuel efficiency and emissions compliance required in modern times. The Swedes actually understand the distinction here themselves. You may notice Hennessey's Lotus on steroids posted in the picture. Koenigsegg dismisses it as nothing more than a Lotus kit car that it is not in the same league. Well, just as the Hennessey Venom GT is not in the same engineering league as the Koenigsegg One:1 so is Koenigsegg not in the same league as the Ferrari LaFerrari, Porsche 918 Spyder, and McLaren P1. Koenigsegg does not seem to understand their design is the past. The 'holy trinity' represents the future. When (or if) their hybrid Regera in development comes out they will then belong in the discussion. For now, they don't.

    Hello, I am working on an open source project and I figured it would be best to collaborate with as many people as possible. This project is for my N55 car, but I bet this will apply to other BMWs too (probably any BMW after 2008). The goal: Make my own progressive methanol injection controller. Purpose: Current meth controllers use different approaches for determining engine load. Some use straight boost (AEM), while others use a much more advanced approach of interpreting sensor values (Aquamist). However, all of these approaches are somewhat "inexact" in my opinion when you consider the goal, which is to inject a certain percentage of the total fuel amount at any given time. The Aquamist is probably the best (and likely more than precise enough for its purpose), but all of these kits still have the issue of installation complexity; I want to avoid tapping a bunch of wires under the hood. The purpose of this project is to create a meth controller that is both very precise and very simple to install. This is also partly driven by my curiosity. Approach: In short, I will obtain realtime engine fuel mass delivery rate data from the OBD interface and use this to drive an Aquamist fast acting valve (FAV). The 2011 E92 335i uses CANbus (500kbps) for OBD-II communications, and the car supports the UDS protocol. The fuel mass delivery rate will be requested using a standard UDS "get ID" (0x22) request. Then, once I have the fuel mass rate, I will convert it in to cc/min (taking in to account the specific gravity of gasoline). The result will be the TOTAL cc/min flow rate for the engine (which can sort of be converted to horsepower if you make some BSFC assumptions). I've created lookup tables (12 entries deep) for various fuel volume flow rates, which will allow for the mapping of the desired meth flow percentage (see MethService.h). The desired meth flow percentage (percentage of total fuel flow rate) will then be mapped to the required PWM duty cycle that the meth injector must be presented with to achieve said flow rate. There's more to it, but this is the general idea. I may update this post later with more details. Until then, see the code for details... Possible Issues: Conflicts with Cobb datalogger. Since there will essentially be two OBD devices on the port, this could cause conflicts. However, since this car uses CAN, it shouldn't be a problem. That's part of the beauty of CANbus. I do make use of the HW filters in the MCP2515 to try to reduce processing overhead for messages I don't care about, but those filters don't inspect deep enough into the message to select only fuel mass responses, so if the Cobb is using the same CAN ID, there could be issues. It all depends on how the Cobb obtains its data. Failure Modes. Special care must be taken to make sure that all possible failure modes result in NO INJECTION of meth. The Code: This project is open source and licenced under the LGPL. The LGPL was chosen because I don't want someone to simply take this code and incorporate it into their closed sorce project without giving proper recognition and support to the community. The LGPL essentially forces any changes to this code to be published openly and forces any closed source programs that make use of this code to provide a means to obtain the LGPL'd portions of the code and re-link to them. In other words, your closed source program CAN use my code, but it should be dynamically linked and you need to provide a copy of my code along with any changes you made to it. That being said, since this is the LGPL and not the GPL, feel free to incorporate this code in to your closed source project, but with restrictions. See the LGPL for more details. The Hardware: I am using a ruggedized version of the Arduino UNO for this project. It's basically the same as the regular Arduino but with a better power supply which can handle 3V-30V and is rated for extended temperatures. I am using the MCP2515 CAN controller with the corresponding transciever, both of which are part of the Jaycon CAN shield for Arduino. I am using the Arduino (OEM) 4 relay board to drive the meth pump and failsafe outputs. I am using the Arduino tinkerkit MOSFET board to drive the Aquamist FAV. This includes a flyback diode, which is nice. Progress I am able to query the fuel mass delivery rate from the ECU and can successfully interpret the values. This was done using some quick test code that I threw together just to prove the concept. Since then, I've been developing this "offline", so I don't know if the current code in the reposity works or not. The full code is basically complete, but I haven't tested it yet. I plan to drive around and log the PWM duty cycle and make sure things are sensible. Then, I will install the actual meth kit and tape the nozzle to the windshield to make sure things work as expected. Please review my code and let me know what you think. Feel free to contribute! Sorry if this post is "incomplete". The project can be found at:

    This bolt on modified Gen V Viper in the videos below is quite impressive. There is good driving to go with it as the owner shifts cleanly and quickly. Previously, we saw a bolt on Gen V Viper beat a PP-Performance tuned CLS63 AMG from a roll and some fanboys doubted the outcome. Well, this bolt on Viper runs not one but two tuned M157 AMG's from PP-Performance. Let's start with the CLS63 AMG said to be a stage 2 PP-Performance tune. The Viper makes easy work of it as they dodge (pardon the pun) traffic: The E63 is said to have the RS850 PP-Performance package with upgraded turbos. The Viper makes easy work of it as well: How about a Mercedes-AMG GT S? Considering the car is stock this race favors the Viper. The AMG GT S gets the hit in the first run. It is quickly overtaken and passed. The second run has a lot of traffic and isn't very clean but the Viper pulls again: Does a tuned SLS AMG fare any better? Nope. The Viper spanks it too: With the AMG's all getting mopped up surely an Aventador will do better? Guess again. The nice thing at least is that this video has honks denoting the start of the race. It doesn't matter, Viper comes out on top yet again: The only real challenger to the Viper is a tuned McLaren MP4-12C. The McLaren does not have a passenger but the Viper does. In the first video it is pretty much door to door with the McLaren appearing to edge. In the second run it looks like the Viper jumps and holds off the McLaren. Overall, this goes to show how potent a bolt on Gen V Dodge Viper is as if this point needs reinforcing yet again. The videos themselves leave a lot to be desired as honks would be much appreciated as would steady camera angles from mounted GoPro's. What we get is a lot of head turning making for jumpy vids so these are not the best but it's still easy to tell the Viper is a beast.

    Anyone remember when the future was bright over at Lotus Cars? Allow us to jog your memory. It was way back in 2010 when Lotus was showing off a bunch of concepts including a 2013 Esprit. Lotus had an awesome presence at car shows and was generating huge buzz with their upcoming lineup. It all fizzled out as you may have noticed there was no Esprit built for 2013. The other four concept cars they debuted in 2010 named the Elan, Eterne, Elite, and Elise also amounted to nothing more than wishful thinking. Lotus did end up producing a new Exige a variant of you see below except they do not sell it in the USA for street use. All they sell is the Evora which pretty much was supposed to be a stopgap car until they launched the new Esprit among others. Lotus did not even have their own booth but a dealer brought this Exige to the LA Auto Show. Their presence is almost non-existent. It is a shame as they produce cars for enthusiasts. With Lotus not being able to even sell their full offering worldwide it is fair to wonder if at least in the US their best days are behind them and if they even have a future in this market. #LAAS2015
