    I want to compare some vehicles. Mostly cars but lightweight gasoline trucks are kind of like cars. weight class 2700-3600lbs power:weight ratio roughly .14285 minimum, prefer .2177 or higher so for example 2800lbs, approx 460bhp (400rwhp through a manual trans) is .14285 standard minimum, we can get this from a typical 2.0L turbo made after 1992 (Nissan and Mitsubishi for example). engine/transmission (drivetrain) economy range 20-35mpg highway steady cruise 70-75mph+ 20mpg is fine for using 87 octane fuel ($2.50/gallon current price) This comparison is done by dollars/miles not miles/gallon. If the engine requires 93 octane all the time (just to cruise) then it must be 30mpg+ to meet the same miles/dollar as 87 octane at 20mpg. Fuel use preferably 87 octane for distance driving is fine 93 octane for normal driving and full power What does the setup produce with these fuel options: How much torque/power on 87? how much on 93? how much with methanol/water? How much on E85? Cost to build the vehicle: original cost of car Cost for setup Ease of building the vehicle: swap kits? oil pan kits? suspension? etc... Summary: weight power (weight) ratio drivetrain spec economy feature (city/highway) using gasoline Fuel option expectations Ease of vehicle concept to reality Cost/availability/location pros/cons Examples using cars I already know Weight: 2800lbs (240sx) power: 400rwhp @ 2800lbs (meets minimum power:weight) drivetrain 2.0L Turbo 5-speed (sr20det) economy: 25city/32mpg highway for newish 9.5:1 compression 2.0T Fuel options: 87 octane max torque 160-170ft*lbs (not a performance car on 87) 93 octane max torque around 400ft*lbs usually and 400rwhp, using OEM piston E85 around 500rwhp but kind of requires a forged piston at this point Ease of vehicle production: Can have the car done running in a single day using typical SR swap techniques (very easy job) Cost: $10,000-$15,000 drivetrain ready to go for 10-20 years reliable pros: easy to swap, easy to tune, huge aftermarket, lightweight, brakes and differential solutions are simple and affordable for 240sx, replacement parts are easy to find currently in CL cons: 87 turns it into a 'regular car' clutch/manual transmission can be bothersome to some and is more maintenance motorsets are harder to find now Example 2 weight 3200lbs (240sx) power: 500-600rwhp @ 3200lbs drivetrain: 4.8-6.0L turbo 4l80e automatic Economy 17city/22highway for used tired engines 150,000miles Fuel options: 87 octane max torque ~300-350ft*lbs (still a fun car on 87) 93 octane max torque around 500ft*lbs +methanol injection around 600ft*lbs before stock engine is questionable (4.8/5.3) E85 1000rwhp is possible on 6L stock engine Ease of vehicle production: Takes about 6 months, most swap parts are available (intermediate level) Cost: $15,000-$20,000 for turn key turbocharged 500rwhp~ pump gas daily drivable, reliable swap pros/cons: -Can make fun torque with 87 octane but mileage is low due to automatic 4l80e. -22mpg using 87 @ $2.50/gallon still beats 30mpg using $3.23/gallon 93 octane. -easy brake upgrade is cheap, and easy/cheap 3.5:1 differential solution (32-spline axles) make the torque reliable SO now lets add some more to this list, I made this fast so Im sure I left out a bunch of pros and cons and all sorts of details. Its just to get started. What we are looking for is the lowest cost, easiest to build, most reliable, etc... best vehicle for the price with the most power and most economy/fun

    I read through a ton of sensor documentation and the real threat seems to be the condensate of water during cold engine starts when the sensor is hot and the exhaust is full of water as a liquid. When you first start the car the liquid water that comes splashing out of that tailpipe etc... that can hit the fully hot sensor and damage it. Since there is no water injection during this period and since water injection does not cause liquid water to form in the exhaust. I think you are being mislead somehow misplacing these two scenarios.

    Just picked up a radenso pro m in addition to my r3, I'll be sure to let you guys know how it is. But it'll definitely be useful for me since I face alot of low powered K band and alternating pulse radar that many detectors including the r3 can't pick up. Managed to snag one for $300CAD so that's really nice.

    Caution light reduction times were company instituted in Texas which made driving more unsafe compared to normal caution light timings. Several municipalities removed and banned these cash generators when this was proven by independent investigation. Also the company take on fines was at least 50%. None of this was done to increase public safety, it was all about revenue flow.

    Don't forget to wrap with a quality PPF to protect against UV. There are UV sealants like OptiLens but it doesn't last so PPF is the best way to go since it is UV + abrasion. Well worth the investment.

    Here is a BMW E92 335xi that is running very well. This is an automatic and all wheel drive example on the stock transmission and stock internal N54 motor. Obviously the Precision 6266 single turbo conversion is providing the grunt. Mod list: - Precision Gen 1 journal 6266 - On3 manifold - 7" FMIC - 2.5" charge pipe - Catless downpipes - 44mm wastegate - 50mm BOV - Teflon E85 rated fuel lines - Motiv flex fuel - Stage 2 LPFP - GFP G-force boost controller - XHP Stage 3 AT TCU flash - BMS AT transmission cooler This 335xi is performing well on the highway with performance that is roughly just ahead of a stock BMW F90 M5. If BimmerBoost were to guess, it looks like a 126 trap car. Speaking of which, it runs a stock F90 M5 twice. The first run is very close but in the second run the 335xi opens up a lead after it had its fuel pump replaced. Next up is a C6 Corvette Z06 with unknown mods which opens a lead only for the 335xi to easily pass it. An F13 M6 with a tune is next. The M6 pulls up top. A W204 C63 AMG Black Series with unknown mods tries its luck. The C63 AMG is easily dispatched. The final cars are a pair of Infiniti Q50's. The first of which is an ECUtek FBO tuned example which gets a jump. The 335xi catches and passes. The second Q50 is a JB4 tuned example that is beaten fairly easily. The final run is a three-way but poor editing gets in the way of seeing how it plays out. Nice runs and a 335xi that performs quite well.

    Earlier this year we saw a McLaren 720S with the Pure Turbos M840T hybrid turbo upgrade producing 936 rear wheel horsepower on race gas. Well, it is now joined by yet another McLaren 720S with the same turbo upgrade producing over 900 wheel horsepower. 932 to the rear wheels to be exact: The 720S is still on the stock internals and stock transmission. Not only is this a ton of power for hybrid turbos it points to built motor McLaren 720S motors with aftermarket turbo housings likely easily going well into the 1XXX horsepower range. The M840T is simply an incredible platform.

    The BMW N63/S63 twin turbo 4.4 liter V8 engine architecture is going to start making some big, big horsepower in 2019. With several large turbo options entering the market and port fuel injection options ready to go 1000+ wheel horsepower is going to become commonplace. At quadruple digit levels of output block integrity becomes a concern. That is where RK Autowerks comes in with their sleeved S63, S63TU, and N63TU engine blocks. How much money? $18,500. No, not cheap and a core exchange is required. If you want to make big power you are eventually going to have to address the block.

    The B58 motor is going to see a ton of aftermarket development especially once the Toyota Supra is out in the wild but Pure Turbos is way ahead of the curve with hybrid turbo upgrades. Their Stage I will provide 480+ wheel horsepower depending on supporting mods and the Stage 2 B58 turbo is good for 540+ wheel horsepower on ethanol. It is going to be interesting to see how Pure Turbos carries over their B58 turbo upgrades to the MKV/A90 Toyota Supra platform and if the Supra B58 design poses any upgrade problems. Definitely a great value at $2500 with a core exchange. 542whp @23psi - Custom Billet Compressor wheel - Custom Turbine wheel - CNC Machined - High Speed VSR Balanced - Spools like the stock turbo

    This is not the first time AMS made big power gain claims on a Mercedes twin turbo V8 with their intake system. The difference here though is that AMS backed up their claims with a dyno graph but the gains are so big they are still hard to believe. A +65 horsepower gain to all four wheel after adding the M157 V8 Alpha carbon fiber intake: That is absolutely massive. To be fair that gain comes on a car tuned on MS109 so obviously aggressively tuned on the stock turbochargers and the factory intake becomes a choke point. The gains on 93 octane pump gas are still huge: 42 horsepower picked up at all four wheels but the graph is quite different. On MS109 the higher rpm's are the choke point whereas here on pump gas you see an increase from 2500-5000 rpm. It is hard to explain why the areas of increase are so different on 93 octane and race gas. BenzBoost would like to see an independent result confirming these gains for the intake system as if accurate this is clearly a must have M157 modification.
