    We're getting extremely close to the official release of the Single Barrel Shotgun HPFP Upgrade. As soon as it's ready there will be a new thread with lots of detailed information and answers to many of your questions. Despite VTT being technically closed for the Holidays, it's very likely that the release will happen and some of the pre-ordered units will be shipped before Christmas. More of the components arrived this week and we are expecting the very last few pieces to arrive on Monday. Please be patient until the official release, in the meantime below are some photos of of the production pieces that came in this week.

    Im not following you. Edit: Forget it, I get what you mean. Honestly we did it because at the time all that was available was the aluminum SMFW and I didn't want to deal with that noisy SOB.

    I would consider it under certain conditions but it would be more terry's situation rather than maintaining the dmfw.

    When you have someone as careful as Dzenno tuning, you can turn off misfire detection, break WHP records, and not worry about losing the motor...:)

    What about the high load misfire(False Knock) issue?

    We ran 700+ WHP for literally hundreds of dyno pulls, thousands of miles on the street, and hundreds more street pulls while tuning. Never a single issue, it was actually just removed about 5 months ago when the clutch started slipping. Flywheel was in great shape, didn't even have a lot of slop in the rubber. He has a SMFW and Stage 3+ in the car now.

    The C6 ZR1 and C7 Z06 have engines have some similarities. They both have the same 6.2 liter displacement and both are supercharged V8 engines. The similarities pretty much end there though as they are two different generations of GM supercharged V8's. The LT4 of course incorporates direct injection which allows higher compression at 10.0:1 compared to the 9.1:1 of the LS9. The LT4 also has a smaller 1.7 liter supercharged compared to the LS9 2.3 liter unit. It is quite a bit smaller but also 20 pounds lighter. They both have the same 6600 rpm redline. Let's break down each motor with GM's own details: LT4 6.2L supercharged engine specifications Displacement (cu in / cc): 376 / 6162 Bore & stroke (in / mm): 4.06 x 3.62 / 103.25 x 92 Block material: cast aluminum Crankshaft: 1538MV steel Connecting rod (in / mm): 6.125 / 155.5 powder-metal steel Piston: forged aluminum with internal ribs; flat-top crown Cylinder head material: A356-T6 rotocast aluminum Induction system: 1.7L supercharger 9.4 psi / 0.65 bar max boost Valvetrain: overhead valve, two valves per cylinder Valve type (intake / exhaust): 54mm solid titanium / 40.4mm sodium-filled Camshaft type: hydraulic roller Intake valve lift (in / mm): 0.492 / 12.5 Exhaust valve lift (in / mm): 0.551 / 14 Duration @ 0.050-in. tappet lift (crank angle degrees, intake / exhaust): 189 / 223 Camshaft lobe separation angle (degrees: 120 Fuel delivery: direct injection Fuel injectors: 25cc/second (1.5L/min) Engine-driven fuel pump (psi / MPa): 2900 / 20 Lubrication system: dry sump, incl. oil-spray piston cooling Compression ratio: 10:1 Horsepower (hp / kW @ rpm): 650 / 485 @ 6400 SAE certified Torque (lb-ft / Nm @ rpm): 650/ 881 @ 3600 SAE certified Max. engine speed (rpm): 6600 Recommended fuel: premium required LS9 6.2L supercharged engine specifications The LT4 is rather at 650 horsepower and 650 lb-ft of torque despite the smaller blower. The LS9 is rated at 638 horsepower and 604 lb-ft of torque. The difference between the two in practice at the wheels is even greater than the crank ratings on paper: 49 wheel horsepower and 84 lb-ft of torque at the wheels difference in favor of the LT4 over the LS9. These numbers really make one wonder why the C7 Z06 is not putting up better performance numbers.

    If you are MSD81 it will work just fine. Nothing you can do (with the open source software) can brick the ECU...

    Map 5 by design will change its target based on the conditions of that moment. If you're looking for a fixed boost map then I'd start with map 2. The BB link seems fine to me. If you have any questions on the open source flash you can always post those here: http://www.n54tech.com/forums/showthread.php?t=20563

    It only goes up to around 26psi IIRC. We use the JB4 to manage fuel from 26psi up to the 30psi target. Since we're working on another controller solution I'm not spending too much time trying to customize the AIC software. But it does work well and fits nicely in the ECU area.

    Did you look at the log? Boost looks to be right on target to me. If you're wondering why the target isn't higher it's probably due to the timing curve and avg ign. Adding in the back end flash will help with that. Anyway if you need addl personal tuning advice you're welcome to post your logs in the n54tech support section for Russell @ BMS to check out.

    I get football a day early so I'm kind of cool with it especially considering Christmas is around the corner. The games will just speed things up. Yay.

    I did click it, as I was shocked it was still listed. For those reaching your site through a google search for S55 turbo upgrades, it appears you have a broken link to a product. The "left it for the designer to see" excuse is poor, as there are 15+ other items and 3 other categories on the product index page for him to look at.

    I get that because I did this same thing, finally after a lot of hard work the single turbo is finally a reality. I hope this happens for you soon too.

    See if you can get some help from someone who has done it before. Installing a diff is not insanely crazy or anything you can definitely do it.
