    Had a chance to meet up with Payam today to tune his new PTE 6466 G2 twin scroll turbocharger. He's running our port injection and a full fuel-it kit (regulator & return line). 100% E85. Per usual I have a limited amount of time so I'll just share the highlights. 1) The 6466 G2 in a twin scroll works really well. Great boost potential and very good HP per PSI. 2) We found Payam's car wanted a lot less timing than I'm used to giving E85 cars. Around 7.5 degrees up top. 3) I tried a few VANOS curves and found the basic Cobb curves worked better than what we have in our ST back end flash files. Better spool and more power. Sigh. I think I'll just change those all back. 4) He ran in to timing drops around 30psi that we couldn't fix by lowering advance further so decided to call it a day for now. Hopefully it runs well at NFZ this weekend!

    The Ford Mustang Ecoboost is becoming a very popular tuner platform. Why shouldn't it? The 2.3 liter turbocharged motor can of course be tuned and the lightweight four-cylinder gives the Mustang great balance and makes it fun to drive namely in the corners. VTT is working on a stock frame turbo upgrade. Readers over on BimmerBoost are familiar with their stock frame upgrades for BMW's. So what will we get out of this upgrade? That remains to be seen. VTT will tear it down and see what they can do. We witnessed a 353 wheel horsepower Mustang Ecoboost set the 1/4 mile record running 11.77 with an aftermarket Precision turbocharger. We have a feeling the stock frame turbocharger can match this and then some. More from @Tony@VargasTurboTech: "We took delivery of our new Mustang Ecoboost turbocharger from Ford last week, and we are getting started on the project. We will be tearing the turbo down, see what is going on inside, and upgrading it to Stage 2 levels. We have a local tester lined up, and look forward to the gains to be had on these cool motors, with just a stock frame upgrade!"

    Very nice numbers here from TopSpeed Motorsports who tuned this AMS Performance Porsche 997.1 Turbo Alpha 9 upgrade package. The tuning was done via a Cobb Accessport. Keep in mind this is a pump gas road race tune so of course there is more in it on race gas. At 22 psi of boost the numbers are 677 horsepower and 623 lb-ft of torque at the wheels. The curve itself looks pretty good with linear power that just keeps climbing and holds to redline: The Alpha 9 package is capable of more as stated (AMS claims 900+ horsepower) but this is a nice pump gas tune. This is what the $20k package includes: Billet turbos, upgraded intercoolers, upgraded injectors, upgraded intakes, new Y-pipe, and intake tubes. An upgraded clutch and exhaust is of course recommended.

    Hot on the heels of the Car and Driver 6-speed manual ATS-V test comes an 8-speed 8L90 automatic ATS-V test from MotorTrend. If we were to guess a deal was struck that Car and Driver would get to publish the numbers first but that MotorTrend would get the automatic press car to test. Magazine politics at work? Just a hunch. Anyway, the MotorTrend figures are more impressive showing 0-60 in 4.0 flat for the auto versus 4.2 for the manual. The 1/4 mile time for the automatic ATS-V is registered as 12.3 @ 114.6 miles per hour. Slightly less than the 115 trap speed recorded for the manual although 3/10's quicker. It also was not tested on a level track so we should in theory see better numbers eventually although these numbers are from a VBOX. It is not as quick or as fast as a DCT BMW M3/M4. Unless owners of the ATS-V come up with a miracle to top the 1/4 mile times we have been seeing from the F80 M3 and F82 M4. Once again, Caddy's boss was wrong about having the Germans whipped in power, torque, and acceleration. Ok, how about the handling? The skidpad figure is .98g or about a wash with the BMW M3/M4. MotorTrend did not delve into the steering feel or handling too much instead saving these details for an upcoming comparison to the BMW M3. That may be why we are missing their figure 8 test numbers. They did state it does feel like a driver's car. The brakes did not fade on the track. The ATS-V stopped from 60 miles per hour in 103 feet. They got 99 feet for the M3. Expect more details in their upcoming comparison as major ones are missing such as the curb weight. We wanted to see how much weight the automatic transmission adds. Regardless, this car is not an M3/M4 killer once again and is certainly not besting the C63 AMG in raw power or acceleration. Is it a better driver's car? Well, we await their direct comparison. 2016 Cadillac ATS-V Coupe BASE PRICE $63,660 PRICE AS TESTED $78,995 VEHICLE LAYOUT Front-engine, RWD, 4-pass, 2-door coupe ENGINE 3.6L/464-hp/445-lb-ft twin-turbo DOHC 24-valve V-6 TRANSMISSION 8-speed automatic WHEELBASE 109.3 in L x W x H 184.7 x 72.5 x 54.5 in 0-60 MPH 4.0 sec QUARTER MILE 12.3 sec @ 114.6 mph BRAKING, 60-0 MPH 103 ft LATERAL ACCELERATION 0.98 g (avg) EPA CITY/HWY/COMB FUEL ECON 16/24/18 mpg ENERGY CONS., CITY/HWY 211/140 kW-hrs/100 miles CO2 EMISSIONS, COMB 1.03 lb/mile

    The Germans over at Autobild got their hands on the new C7 Corvette Z06 and their testing shows incredible performance figures. Specifically its laptime around the Sachsenring course in Germany. Let's put the Corvette laptime in context with some stiff competition. Here are the top 10 Sachsenring laptimes: 1. Chevrolet Corvette Stingray Z06 1:30.47 2. Porsche 911 Turbo S (991) 1:32.51 3. Ferrari 458 Speciale 1:32.76 4. Lamborghini Huracan LP 610-4 1:32.84 5. Porsche 911 Turbo (991) 1:32.92 6. Porsche 911 GT3 1:32.97 7. McLaren 650 S 1:33.15 8. Porsche 911 Turbo S Cabriolet (991) 1:33.23 9. Mercedes SLS AMG Black Series 1:33.38 10. Porsche 911 GT2 RS 1:33.51 The Z06 beats its next closest rival, the Porsche 911 (991) Turbo S , by over two seconds. In other words, an eternity. That is an epic beatdown. The course itself is 2.28 miles long and fairly tight and technical with long sweepers featuring elevation changes. The track is well known in MotoGP circles. For the Z06 to crush the 911 Turbo S laptime to such a degree on this circuit is impressive. Incredibly impressive. Especially considering it was done by the Germans who dethroned their own German car they love to worship.

    Very interesting runs here with interesting results. The CLA45 AMG is stock. Obviously in stock form with its 355 horsepower M133 2.0 liter four-cylinder motor it is much quicker than the MKVII Volkswagen GTI. 45 AMG output is roughly in the ~330 wheel horsepower range stock and the GTI is in the ~220 wheel horsepower range stock. That is a very big spread between the two 2.0 liter four-cylinder direct injected motors. However, that is what tuning is for and here is the mod list for the cars: CLA45AMG - Stock, VDC off, Sports mode, 19" wheels MK7 GTI - Revo, Milltek Full Exhaust, Revo Intake, 19" wheels, wheel HP - 300 So the GTI is around the 300 wheel horsepower mark so it is still down on the CLA45 AMG slightly. However, the GTI has some advantage in a race like this namely that the Golf is roughly 500 pounds lighter and it sends its power to the front wheels rather than all four. In a roll on race this pays major dividends as the GTI pulls away. The first race has the CLA45 AMG on the inside tract and it gets a bit of a jump. The GTI does run it down though. The second run really illustrates the difference with a more even straightaway and start. The GTI just pulls decisively away. The CLA45 AMG of course can be tuned as well but the GTI will always have the advantage of being much lighter. It will be interesting to see how much weight the upcoming R400/R420 model adds with its beefed up components and all wheel drive. Very impressive performance from the VW:

    Very cool race here between a Lamborghini Huracan that is stock except for an exhaust system and a modified C7 Corvette Z06. The Z06 is the same car we saw go 9.891 @ 141.64 in the 1/4 mile on E85. The Z06 also is a 7-speed manual car meaning driver skill plays a significant part. The first run is from a roll. The Huracan is given the hit and takes a lead. The dual clutch transmission helps hold off the Z06 on the first couple gear shifts. Once they get into higher speeds though the power difference shows and the Z06 just pulls away. It's clearly the more powerful car here. What is nice to see is that they also go from a stop. The advantage is squarely in the Huracan's court as it has all wheel drive. That is likely why the Z06 gets the hit off the line. It takes off but you soon see its tires go up in smoke. The Huracan quickly passes by it opening a lead thanks to its traction advantage and dual clutch transmission. Unfortunately we only get one camera angle but it is easy to tell the Huracan is ahead of the Z06 and holding it off. It takes an eternity for the Z06 to catch up which it eventually does. In a street matchup from a stop the Huracan has the advantage unless a Z06 is wearing drag rubber in anticipation of such an encounter. Very nice runs and high quality video to boot. The Huracan does an admirable job considering it is naturally aspirated and has less power and torque:

    Great tuning here from Eurocharged. The baseline figure you see is from the Porsche 997.2 Turbo. As you likely know the 997.2 switched to a direct injected 3.8 liter twin turbo flat-6. The power and torque figures are strong with 461 horsepower and 469 lb-ft of torque at the wheels. That is on 93 octane pump fuel. Considering the 997.2 Turbo got a 20 horsepower bump on paper to 493 horsepower it certainly looks to be considerably underrated. Let's take a look a the tuned figures also on pump gas. This is another one of those times where peak horsepower does not tell the whole story. Peak horsepower goes from 461 to 505 at the wheels for a gain of 44 horsepower at the wheels. However, look at the torque curve. At 3500 rpm there is an additional 120 lb-ft of torque at the wheels. That is a strong increase down low which is night and day over stock. It also results in an additional 80 horsepower at the wheels at that same rpm. You will notice there are torque gains throughout the entire curve. The difference in area under the curve from 2750 to 5000 rpm is huge. Not bad for just a flash tune only on pump gas, eh?

    Yesterday we saw a tuned Volkswagen MKVII GTI pull away from a stock CLA45 AMG on the highway. Well, in the interest of fairness it's time to see how a tuned 45 AMG M133 does against some tuned MKVII Golf's. The MKVII VW Golf's in the video are not the GTI model but the R. In theory, a tuned Golf R should be quicker than the GTI but it is heavier due to its all wheel drive. The A45 AMG of course has all wheel drive and is a bit heavier than either. The vehicles racing all feature dual clutch transmissions. Here is the mod list for each vehicle: Camera car Golf R - custom exhaust and intake, Stage 2 Revo tune Second Golf R - custom downpipe and intake, HG Motorsports intercooler, and Stage 2 Revo tune Mercedes A45 AMG - Renntech Tuning Box, cat delete, Rebellion TCU remap The first run video is a low speed roll with the A45 AMG versus the camera Golf R. The A45 AMG just pulls away steadily as the cars dodge traffic (Russians, naturally). The second run video features all three cars lined up. The Golf R's are pretty close to one another and essentially even. The A45 AMG though pulls away decisively and continues to steadily pull. What is interesting is that this not with any Renntech flash tuning but just the Renntech piggyback box. The AMG M133 four-cylinder takes this one easily.

    3344 lbs and almost 50/50 weight distribution. That would be a fun car to toss around.

    Sweeeeet! Thank you Joe and Terry! I am definitely satisfied with my results from what I have gone through this week haha! Will have to take a look at my plugs again and check cyl 4. It was giving us some problems today, but we will get to the bottom of it. Another testing we did today was turbo filter and its restriction with the BMS Shorty VS KN 2510. The KN 2510 previously proved to be a restriction somewhere about 660whp with our Comp 6465 turbo testing. We removed the intake and automatically on same boost level and tune, we made another 25whp. Today on the dyno (Log 3) at 30 psi with BMS Shorty it made 752whp. We pulled the intake off on dyno (Log 2) and it made 757whp it only made 5whp difference. We can say that this filter will have negligible restriction for high hp applications such as this. Really happy with this outcome and dyno day!
