    The 435i in the video is tuned with a BMS JB5 pushing roughly 17.5 psi of boost on E85. It has bolt on mods consisting of a downpipe and intake. The 3.0 liter N55 is matching up against a stock W205 Mercedes-AMG C63 S. Even though the Mercedes is stock and the heavier chassis it is bringing with it a 4.0 liter M177 twin turbo V8 and well over 500 horsepower. A stock M177 S is in the ~465 whp range with ~490 lb-ft of torque at the wheels. The 435i is simply overmatched. It hangs in fairly well all things considering but it struggles against a stock M177 which means if the C63 gets a tune it will be in another zip code.

    Sorry if this is a commonly asked thread. I'm not a car guy (roommate is though), but I've been searching on what to do first and it seems there's so many options for everything. This is my daily car, so I don't want to do anything that would only be done for 'racing' in particular that might cause damage if done for awhile. I've been looking at getting a Cobb Accessport, but then read that their considered outdated now. JB4 I heard you have to send in your ecu to have it installed, and MHD I'm considering now although would need an android device to use, so does anyone have any recommendations? I know, the MHD vs JB4 has been done to death, but I'm mainly looking for what you think would be best for a daily driver like me with not much experience in tuning anything (although I'd like to get great performance). I then heard downpipe was crucial, mostly catless downpipe, but then I was told that would trigger the check-engine light and then I'd have to take it in to get tuned? Also, what's the difference between a full exhaust system like - bmw-3-series-cat-back-exhaust-system - is it strictly the noise or is there a performance gain from the 1400 exhaust systems vs the 350 catless downpipe? My roommate suggested exhaust first then tuner, but I cannot decide, do I need the full system or just the downpipe? If the system is 1000+ more and it's only for sound then I doubt I'll go for it. Thanks for any information I could get, I'm new to all this.

    Well, since I sold my custom exhaust when going turbo that left me in a bit of a problem as we're going back to a stock internal supercharged setup. The solution? ARH or American Racing Headers full system: I'm particularly interested in the headers: Went catless with no resonators. We'll see what the car sounds like and dynos maybe as early as this week. Go big or go home, right?

    I have brought some Wiseco forged Pistons for my forged 2.8l m50nv build and there meant for 8.0:1 compression ratio but I am concerned about the engine being slow to build boost and laggy at 8.0:1. The rest of the build spec is holset hx40 14cm on twinscroll equal length manifold with 3" down pipe and 3" intercoler piping, mishimoto g line intercoler, eagle rods, standard nv cams for now (thinking about catcams turbo cams) link G4+ stand alone. Could anyone shed any light on if it's going to take ages to build boost with that turbo at that compression ratio? Only after a rough ideas as I understand there's a lot that influences spool time but from what I can read about the effects of compression ratio it might be too low at 8.0:1 with the engine previously being around 10.0:1 factory? My my previous build was m50nv block (1mm shorter than tu a apparently) and head, 2.8 standard internals .140mls with a holset hx35 12cm with the same manifold and intercoler setup as above and that dove really nicely, 1 bar of boost by 3.5k rpm but I don't think that was anywhere near 8.0:1 ratio as the engine made 440bhp and 500ftlb knock limited standard fuel. I would lke, the forged build to be some where near the old setup if possible, I expect slightly more boost build time with having a bigger turbo but just don't want it to say make 1 bar boost at like 5k rpm and drive shit as its a road car any enlightenment would be very helpful, thanks

    Automotive forums are a double edged sword. They can be a repository of valuable information with incredibly knowledgeable and helpful members. They can also have know-it-all's who spread misinformation and think they are never wrong. The BoostAddict forums are worth every penny, right?

    This is an interesting comparison as it is a bit of sibling on sibling rivalry. Both Audi and Porsche are under the VAG umbrella so they are part of the same company yet the execution and vision of both of these cars are completely different. The TT-RS is the brute. It has more power and it's all about putting it down to all four wheels to dust its competition. That is not to say it does not shine in the corners as it does but it just does not do it like the Cayman S. The Cayman S is lighter with a mid-engine layout. This example tested is a 6-speed manual version. Perhaps that says plenty as to the intended audience. The TT-RS is dual clutch only. The Cayman S offers a PDK dual clutch as an option. Right off the bat you know the Cayman is at a disadvantage due to the transmission choice. Yet, maybe it has an advantage in the eyes of a purist driver? Car and Driver thinks the Porsche manual is the best in the business. The interaction provided outweighs the tenths of a second lost in shift time. It wouldn't matter if the Cayman S had a PDK anyway. The TT-RS is getting to 60 in 3.2 seconds. It gets to 100 in 8.1 seconds or over a second faster than the 718 S. The 1/4 mile sprint takes 11.6 seconds at 119 miles per hour. Even a 911 Carrera PDK would lose the straightline battle. So what? This is about which is the better sports car. The Audi has 60% of its weight on the front nose. Yes, 60%. The 718 by contrast has a 44.6/55.4 percent front to rear split. It's also lighter 175 pounds at 3102. The TT-RS pulls more on the skidpad at 1.05g to 1.04g but the Cayman S gets through the slalom at 47.1 mph compared to 46.7 mph. Sometimes it isn't all about outright grip but transitions and the Cayman clearly has the better combination of grip, weight, and balance. Car and Driver picks the Cayman S as the better sports car. They say it is one of the best cars in the world at any price point. They're not wrong. Imagine if the 718 S had the TT-RS powerplant though. Wouldn't that be something? 2018 Audi TT RS 2017 Porsche 718 Cayman S VEHICLE PRICE AS TESTED $80,200 $81,590 BASE PRICE $65,875 $67,350 DIMENSIONS LENGTH 165.0 in 172.4 in WIDTH 72.1 in 70.9 in HEIGHT 52.9 in 50.2 in WHEELBASE 98.6 in 97.4 in FRONT TRACK 61.6 in 59.6 in REAR TRACK 60.7 in 60.6 in INTERIOR VOLUME F: 47 cu ft R: 27 cu ft F: 49 cu ft TRUNK 12 cu ft 15 cu ft POWERTRAIN ENGINE turbocharged DOHC 20-valve inline-5 151 cu in (2480 cc) turbocharged DOHC 16-valve flat-4 152 cu in (2497 cc) POWER HP @ RPM 400 @ 7000 350 @ 6500 TORQUE LB-FT @ RPM 354 @ 1700 309 @ 1900 REDLINE / FUEL CUTOFF 7000/7200 rpm 7400/7500 rpm LB PER HP 8.2 8.9 DRIVELINE TRANSMISSION 7-speed dual-clutch automatic 6-speed manual DRIVEN WHEELS all rear GEAR RATIO:1/ MPH PER 1000 RPM/ MAX MPH 1 3.56/5.2/37 2 2.53/8.6/62 3 1.68/13.0/94 4 1.02/18.2/131 5 0.79/23.5/169 6 0.76/28.7/174 7 0.64/34.1/170 1 3.31/6.2/47 2 1.95/10.6/80 3 1.41/14.6/110 4 1.13/18.2/136 5 0.95/21.7/163 6 0.81/25.3/177 FINAL-DRIVE RATIO:1 4.06, 3.45* 3.89, limited-slip differential CHASSIS SUSPENSION F: struts, coil springs, anti-roll bar R: multilink, coil springs, anti-roll bar F: struts, coil springs, anti-roll bar R: struts, coil springs, anti-roll bar BRAKES F: 14.6-inch vented, cross-drilled ceramic disc R: 12.2-inch vented disc F: 13.0-inch vented, cross-drilled disc R: 11.8-inch vented, cross-drilled disc STABILITY CONTROL fully defeatable, competition mode, launch control fully defeatable TIRES Pirelli P Zero 255/30ZR-20 (92Y) Pirelli P Zero F: 235/35ZR-20 (88Y) R: 265/35ZR-20 (95Y) C/D TEST RESULTS ACCELERATION 0–30 MPH 1.2 sec 1.6 sec 0–60 MPH 3.2 sec 4.1 sec 0–100 MPH 8.1 sec 9.3 sec 0–150 MPH 21.4 sec 23.7 sec ¼-MILE @ MPH 11.6 sec @ 119 12.4 sec @ 115 ROLLING START, 5–60 MPH 4.1 sec 5.5 sec TOP GEAR, 30–50 MPH 2.6 sec 7.9 sec TOP GEAR, 50–70 MPH 3.0 sec 5.4 sec TOP SPEED 174 mph (gov ltd, mfr’s claim) 177 mph (drag ltd, mfr’s claim) CHASSIS BRAKING 70–0 MPH 140 ft 144 ft ROADHOLDING, 300-FT-DIA SKIDPAD 1.05 g 1.04 g 610-FT SLALOM 46.7 mph 47.1 mph WEIGHT CURB 3277 lb 3102 lb %FRONT/%REAR 60.5/39.5 44.6/55.4 FUEL TANK 14.5 gal 16.9 gal RATING 93 octane 93 octane EPA COMBINED/CITY/HWY 22/19/29 mpg 22/20/26 mpg C/D 750-MILE TRIP 20 mpg 20 mpg SOUND LEVEL IDLE 46 dBA 51 dBA FULL THROTTLE 83 dBA 86 dBA 70-MPH CRUISE 70 dBA 73 dBA *The first ratio is for gears 1, 4, and 5.
