    Hey everyone! Extremely excited to post a little more data on what we're doing over at Vargas Performance Group. We're testing a prototype hpfp system, and simultaneously testing control over it. Our testing started with normal E85, then Tony switched to E98 to really put the fueling system through its paces. Disclaimers/Info: -"proof of concept" prototype hpfp system -prototype is called "the prototype" because it's not ready for production, meaning we have significant work to do in order to turn this into a product ready to sell, if ever -indicates that DI only 600+ whp is possible on stock injectors -stopped log at 6300 due to auto transmission (have other logs revving higher, fuel pressure & A/F is still good but those weren't the glorious dyno this is) -Rail pressure was much smoother when we used higher targets, there is some control system learning that occurs -this dyno was done with no learning Run Data: Boost: ~28 psi Timing: ~9* Fuel: E98 Low Pressure Fuel Pump: Fuel-it! Stg 3 High Pressure Fuel System: Prototype Port Injection: None Methanol Injection: None Future Plans: -More DI only testing and prototype development -Examination of feasibility for production type configuration/implementation Take Home: -There is room to run over 600 whp direct injection only -Injectors and injector window is not an issue yet -Vargas continues to innovate and push hard

    Hello all, I am new to the forum, and in hopes of selling my Burger Motorsports Stage 1, N55 Plug and Play Tuner. The reason I am retiring my Stage 1 is because I will be upgrading to a JB4 and no longer need the Stage 1. This is practically brand new, though will sell at a right price, Obviously lower than what they retail at ($379) Let me know if you are interested.

    On paper the facelifted 911 Turbo S is favored. It has 580 horsepower to the GT3 RS 500 plus the twin turbochargers boost its torque figure to 516 lb-ft. The naturally aspirated 4.0 liter flat-6 GT3 RS on the other hand makes do with 'only' 338 lb-ft of torque. What the GT3 RS has going for it is a wider rev range meaning it is geared shorter plus it sends power to the rear wheels meaning it has lower drivetrain losses compared to the all wheel drive turbo. This also means it is lighter by a good 400 pounds. If you buy a GT3 RS to race in a straight line you bought the wrong car. The Turbo S is easier to tune and when making big power it can maintain traction. Plus it does not suffer from the same aerodynamic drag as downforce in corners is not the primary concern. The Turbo S makes easy work of the GT3 RS in similar fashion to the Huracan we saw beat up the GT3 RS recently. It seems the Huracan and the Turbo S are more of a match for each other.

    Interesting run here as two tuners put forth S63TU's they tuned against each other with the winner taking $10k. Evotech apparently has a reputation in Europe as not wanting to race unless it is for money otherwise it is a waste of their time. The funny thing is they were not willing to race for $10k but instead agreed to a $1500 run. What happened to the confidence Evotech? Frankly, BimmerBoost does not have too much faith in Evotech's claims as they seem to be exaggerated anyway. The F10 M5 camera car is tuned by BimmerBoost member @lfelunden who has not yet decided on a name for his new tuning company. The M6 Gran Coupe is heavier than the standard M6 so weights are pretty even here. It is surprising how easily the M5 pulls considering both cars are bolt on tuned and if racing for money one would assume at their best. No comment from Oliver Neumann the owner at Evotech at this time although we are told the race loser paid up. BMW M5 F10 HCP mods: Stage 3 software by HCP, catless downpipes and K&N drop-in filters M6 F06 Evotech: Stage 2+ software (Evotechs most powerful), akrapovic exhaust, catless downpipes and intake

    So, I bought a Silverado and I have to unload my S4 before I have too many car payments. I purchased it Last July from vortex member VWRACR, with 73.5k miles. He bought it from the orginial owner's dealership as a CPO vehicle that was traded in. Besides all of the options that are included with the prestige package, including B&O stereo, I bought it with the following additions: H&R Street Performance Coil Over Kit, rear shocks upgraded to Bilsteins. Malone Stage II tune - this is THE car that was dynoed at 415WHP and 377WTQ. ( -this is the car that is on their website. Stage II supercharger pulley. AWE tuning "cold front" coolant reservoir. APR coolant performance system coolant tank. AFCO Ford GT500 double pass heat exchanger. USP Motorsports intake. All interior lighting converted to LED Carbon fiber mirror housings. Debadged with painted and cleared taillights (light smoke, not overdone, flawless finish.) RS4 black front grille. P3 cars vent gauge with boost, battery voltage, air temp, exhaust temp, 0-60, coolant temp, and ignition timing. Audi RS4 steering wheel. 034 motorsports transmission insert. 034 motorsports differential inserts. 034 stainless steel downpipes. rear and side windows tinted, top of front windshield. *I'm sure I'm missing something* After purchasing, I've done a few more things to it, and they are: Milltek stainless steel resonated cat-back exhaust. LED license plate bulbs Opt7 Fluxbeam LED foglight bulbs. Cross-drilled rotors with OEM pads. 84k miles. AEM MAP/MAF based progressive methanol injection. Audi 10 spoke 19" wheels with 255/35/19" Dunlop Signature HP all season tires. SPEC stage 3+ single disk clutch with new OEM flywheel at 82k miles. Intake valve carbon cleaning at 86k-ish miles. New NGK iridium plugs at the same time. some minor VAG-Com tweaks (seatbelt chime) If I think of anything else, I'll post that up as well. All maintenance is up to date, I personally changed the oil every 5k while owning the car, and also maintained everything else that requires service. This car has never left me stranded, and the only issues, outside of regular maintenance was a fuel tank rear sending unit, which I replaced about a month ago. I have a few pictures posted on photobucket, and will post more once I gather them all up between all my electronic crap. I replaced the air filter last weekend, and gave it a little bath. I also pulled the stupid front plate off for pics: There's a few random pics and whatnot here:

    rac replied to a thread Stock turbo record? Nizpro 335 in N54 11.2 is right up there. 11.013 is the quickest posted for stock turbo 335i that i see in the link. Looks like Hotrod had a nitrous shot for 11.11, as did a few other guys at around those times.

    I think from that last picture it's pretty clear that the hose, as it is, doesn't fit. I have a work around idea. Just waiting to let the shop know. I'll report back when I know more. WM
