    Put the car on the dyno tonight, for a few runs with the new intakes on. The results were pretty much as expected, we can most likely get more power out of the car, but 640WHP on stage 2's (or RB's), very very doubtful. These results were had with no tuner on hand, Dzenno is Skiing, and made me 2 maps one with low timing and one with the high timing (the same timing we ran last time on the dyno), well due to a miscommunication on my part they were left for IJEOS(shop car), instead of I8AOS for the car these are on. So they were unusable meaning we had one back end flash, with timing set to 10-13.5 up top, which is 2 degrees less then we ran on the previous dyno session records. We also were having a very hard time getting boost smooth in the JB, Terry, and I worked at it for about 20-40 logs, and got it to this level of smoothness, for some reason the PID had to be dropped way down as very small PWM changes were making big swings in boost, even with PID this low boost would still do weird things. It would spool then quickly drop boost, then build it again, which is that little depression in TQ you see from 3500-4250 or so, after that boost would smooth out, and track pretty well to redline. On the previous dyno the Stage 2 record was achieved on 29psi peak to 17.5 psi at redline as that is all we could make. These numbers were achieved with 27 psi peak to 22 psi at redline. We couldn't go any higher as we were getting a LOT of corrections, and LPFP was going nuts, but we can easily hold 25+ psi to redline if we can get the other issues figured out, but BP and shaft speed with those little compressors is going to be up there, and not healthy. If we matched the previous boost in the midrange, and fixed the boost drop off then rebuild issue, the curves down low would basically be identical. As far as LPFP something is really going on there, I will investigate tomorrow, as its pretty scary. With this against us, we still managed to make 576WHP/615WTQ with all these issues, once Dzenno gets back, and we can have a tuner on hand as we dyno, as well as get the LPFP, and boost figured out, the graph will smooth way out, and we have no doubt should achieve 600WHP with a few more psi, and less timing corrections. Either way, the intakes do exactly advertised, offer you much more flow to redline, and a much more flat power curve where it counts in the high end of the rev band. I threw a graph in there against 2+ as well, there really is no comparison, 2+ leaves the 15T's in the dust on about the same boost midrange and 2 psi more up top. All, and all we are happy, and these delivered as expected, once we get tuning sorted, we should have nice clean graph, and right around 600/600.

    What is the best upgraded turbo and fuel option for FBO on 93 octane? I do not want to run meth and the car is a daily driver. I see lots of dynos and claims for ethanol whp records but the nearest E85 station is 45 mins away from me. I do have quick access to 100+ octane though. Am i really going to gain much by going to stage 2 over stage 1 twins on 93?

    The M133 engine is finally getting more flash options on the market. Up until now Renntech was the only tuner offering a real flash tune. The vast majority of the other M133 tuning options were piggyback tunes which of course have their plusses and minuses depending on your tuning goals. Flash tunes tends to offer more control over various parameters but it is ultimately personal preference. What is important is that M133 tuning is taking strides forward which is good for everyone. Eurocharged recorded a baseline wheel horsepower figure of 330. After the tune this rises to 380 for a very impressive gain of 50 wheel horsepower. The baseline torque figure is 334 lb-ft at the wheels. After the tune the peak torque rises to 430 lb-ft at the wheels for a gain of 96 lb-ft. The M133 definitely offers incredibly torque stock and tuned. The turbo does look like it runs out of steam past 5500 rpm though as if the torque did not drop off so sharply the M133 would easily make over 400 wheel horsepower. The Eurocharged tune retails for a very reasonable $999. The ECU must be sent in to either the Houston or Toronto location. OBD-II flashing is not yet possible but that will come with time. This is just the beginning but the future of M133 tuning certainly is bright.

    Since the launch of the MP4-12C McLaren has continued to refine the platform. They offered a 616 horsepower ECU tune upgrade for the MP4-12C. They then launched the 650S model with refined styling and more power. It appears the 650S is about to be updated as well with a new 675 LT model. Whether the styling changes is anyone's guess but the test mule does have the front and rear lights covered. Does this mean more P1 inspired touches? That can only be a good thing. Regarding the motor it is getting a power boost to 666 horsepower. How this will be achieved has yet to be disclosed but it could be with changes to the tune or exhaust. They likely will refine both aspects. The car is expected to also drop a significant 100 kilograms. That is a significant drop and should make the 675 LT model just absurdly fast on top of the already very fast 650S. Expect an official reveal in Geneva in March and for the model to be limited to 250 units rather than for it to replace the 650S outright. Source

    Fishayyy started a thread Slipping clutch? in N54
    Well it seems my clutch is starting to vibrate when it engages in 1st gear unless I really baby the engagement and after I drive hard or just drive for a long time I can smell a burning smell coming from somewhere. So considering all of that I'm assuming my clutch is starting to go out, should I get a new one? I've been thinking about getting a Motiv or a Spec Twin Disc clutch with a SMFW, but I really haven't looked too much into aftermarket clutches yet.

    Fabspeed announced last year they would offer a tune for the Porsche 991 Turbo and 991 Turbo S. The initial graph they posted showed 95 horsepower gains although the graph was from a European dyno showing crank figures. The European dyno makes sense as it appears Fabspeed is rebranding a European piggyback. At the time Fabspeed stated nobody had the ability to flash the 991 Turbo ECU which was incorrect as GIAC had and has that ability. At $4995 it is difficult to defend the Fabspeed piggyback with the GIAC flash option on the market. Porsche tax? Yep. Regardless here are the dyno results for the Fabspeed module on a Porsche 991 Turbo. All wheel horsepower goes from 486 wheel horsepower to 537 wheel horsepower for a gain of 51 horses at all four wheels. The torque figure is very impressive for the 991 Turbo even in stock form as it puts down 607 lb-ft to all four wheels. With the tune 672 lb-ft at the wheels is available as early as 2600 rpm making for a huge kick in the pants down low. $5k for this module though? It would make sense as a value option compared to the GIAC flash. As it stands... well, decide for yourself.

    I am attempting to do some research on how inlet air temperatures are being effected by my ESS VT-650 kit and how efficient the intercooler design is. I am running the BMW Data logger program while conducting a few maximum rpm pulls on the highway. This was in no way a controlled test as I am just starting this and wanted to get a basic idea of what is going on under the hood. I am also having trouble with the BMW data logger continuously dropping offline. Ambient temperature was 60 degrees. While driving at 70mph and engine completely warmed up IATs began at 83-85 degrees. After only two 3rd to the top of 4th gear pulls IATs yielded a 148 degree peak. It took about 5 minutes for IATs to come down to 90 degrees where it stabilized. After the IATs stabilized I pulled over and checked under the hood temperatures. Using an infrared thermometer the large air filter measured 100 degrees. The small air filter measured 130 degrees. I am looking into putting a temperature sensor at the filter to get a more accurate reading of how hot the air is that is actually being sucked in. Even though this was a very rough test, the results do not look good to me. IATs stabilizing 30 degrees above ambient at highway speeds does not seem efficient. Also, seeing 90 degrees above ambient after a few hard pulls on only 7psi does not seem good either. Supercharger outlet temperature = ambient + (10 * psi) right? I welcome any comments. Any boost experts out there?

    An absolutely awesome Vengeance Racing VRSC850 package build here. The C7 Stingray LT1 gets 12 psi of boost courtesy of a Paxton Novi 1500 centrifugal blower. The owner opted to stroke the motor getting a new crank along with new forged internals. In addition American Racing headers Vengeance Racings ported LT1 heads, a VR cam, and methanol injection are added into the mix. The result on 12 psi and 93 octane pump gas with the meth is 851 horsepower at the wheels and 794 lb-ft of torque at the wheels. Performance that can be replicated every day if the owner desires. The full build is below. It certainly makes a strong argument for modifying a base base C7 for power rather than the C7 Z06. Recently, we had a client of ours come by with his white C7 Corvette looking for some changes. He wanted to do some simpler modifications like lowering the car, exhaust and short shifter, but the real goal was to extract as much as he could out of the C7 platform on pump gas. With our proven C7 Corvette Performance Packages, it made the decision for us and the client easy. We decided to move right on to the top and go with our VRSC850 Performance Package with the ECS Novi 1500 supercharger running at 12psi. With all of the supporting mods, this would equate to great power and reliability that was ready for the street. The first stage in the process of building out the VRSC850 package is to take care of the short block. The bottom end of the LT1 power plant is stroked out to 416c.i. and the internals go to a forged rotating assembly thanks to products from Callies, Wiseco, ARP and Calico. In addition to the short block mods, a set of VR CNC ported LT1 cylinder heads are outfitted and VR stage 1 416 cam is installed. After motor assembly is complete, we bolted up the ECS 1500 supercharger and laid the motor in the cradle. As the air exits, it now passes through a set of American Racing Headers longtube headers. We also installed the AlkyControl dual nozzle methanol injection system to cool the charge and add fueling/octane to the system for more power. Modifications Installed VRSC850 C7 Corvette Performance Package Includes: VR 416c.i. LT1 Stroker bottom end - Callies 4" crank/Callies 6.125 Rods/Wiseco Custom Forged Pistons/Calico coated bearings/ARP fasteners VR CNC Ported LT1 Cylinder Heads VR Custom Camshaft Kit - VR Stage I 416 camshaft American Racing Headers Longtube Header System B&B Bullet Exhaust System MGW Short Throw Shifter ECS Novi 1500 Supercharger @ 12psi AlkyControl Dual Nozzle Methanol Lowered on OEM bolts OEM Intake Manifold Vengeance Racing Professional Installation Vengeance Racing Custom ECU Calibration How how did the new build on this C7 perform? Final power levels after our Vengeance Racing custom ECU calibration came out to 851.82rwhp and 794.08wtq on 93oct and meth injection!

    Weistec Engineering held a Concourse event at their facility this past weekend in Santa Ana, California. The turnout was quite large as you can see. Fortunately, Weistec has a good amount of parking around their ample sized facility which was able to accommodate. Weistec is primarily known for their Mercedes-AMG work but as you can see what they do generates interest from enthusiasts across the spectrum. In addition to a variety of Benzes you will see everything from Lamborghinis, to Ferraris, to bikes, etc. Turnouts like this prove how big of a name Weistec has become. If they continue to do this event yearly they will likely soon need a bigger venue. Congratulations to @Weistec for how they have come and a successful event. Enjoy the photos.
