  1. So this is what happens when you change from 22" wheels to 20", and don't correct the final drive ratio in the system. It's our mistake and we're pretty embarrassed, but it is what it is. As noted above, we had a bad injector on this build and had the car back to resolve. When we put it back on the dyno to validate, we also changed out the rear wheels to 20" rims so we had a good comparison to most of the other cars we do. What we didn't do was change the tire size in his vehicle's base data file, making the RPM appear lower. So, what we got is the graph in the post above, the final HP number didn't change of course, but the torque curve was skewed, stacking the TQ at the bottom of the run. I spoke with JJ on friday explaining what happened and he agreed to let me posted the corrected graph below. Again, we're sorry for the mix up and appreciate the opportunity to clear this up...
  2. The first pulley was a 3.2"; showed 8 lbs on the dyno but was spiking to 10 - 11 on the street. So we backed up to a 3.4", and loaded the $*** out of the dyno to extend the pull. We are seeing 7 lbs with spikes to 8 at the top of the run. (IATs 25 to 30° over ambient!). I've got the car at home tonight, doing some street pulls to be sure we've got a leash on this beast. Revs so quick, 1st gear is pretty much a vestigial organ at this point...
  3. Quick update, JJ did a video he could replay later, looks like the AFRs at WOT are fine but the boost is higher then we'd like to see on a stock 5.7, so we are doing a pulley and touching up the tune.
  4. JJ, PM sent. This blower is a new and very advanced design, so the need for some tweaking is not unexpected. On the AFR, the PCM commands 14.7 in closed loop, once the vehicle is at operating temperature, which is stoichiometric AFR for gasoline. At WOT you should be seeing 11.5 to 11.8. This build was 11.6 to 11.8 @ WOT on the dyno, boost was 7 - 8 lbs. If you are seeing 12.0 WOT/AFR or above we need to look at it again. DO NOT make WOT runs with the AFR over 12.0 on a stock motor.
  5. = ] All that and no knock & the plugs are optimal. It's post Cat and on the race tune. Street tune is right at 11.8. This motor is just the thing for 5.7 builds.
  6. And, the mask is not required!
  7. Ya, the oil pan is stained, you should have seen it before I started cleaning it (and the mounts)...but yes we believe in cleaning parts before we put them back on engines.
  8. By "Teflon" coating do you mean the dark, ablative coating on the rotors? Have you inspected the case for cracks or other pressure stress related failures?
  9. , yes doing that without doing a cam wouldn't make sense. 25 HP for the head swap is the number I've seen. Don't have any HP numbers on the intake. But these parts are intended for "builds", so the final HP number will depend on the sum of the parts. In particular, the intake is intended as a replacement for the plastic part on builds using NOs, centrifugal blowers, turbos and resto-mods.
  10. Both the RPM heads and the Victor II intake will be available mid to late first quarter 2017. Pricing has not been set, but will be "very competitive". There are several other very cool items that are coming out in the very near future, stay tuned!
  11. Blocks are $1,550 plus shipping (NO CORE CHARGE). Very few left at this price...
  12. Yes, these are the heavy duty heads used on the 6.4 trucks. The casting is identical to the Hellcat head and uses the same heat-treated 356-T6 material; these heads also have steel guides and seats. The main difference is the Big Gas heads have valves that are comparable to the 6.4, while the Hellcat has special alloy, sodium filled valves. Also, these heads have the intake manifold bolts in the correct location for the 6.4; where the Hellcat head's bolt holes are offset for the blower, and are not direct bolt on replacements.
  13. Ride height is adjustable. With 1 1/2" pre-load the car sits at about stock SRT height. Once the spring is pre-loaded it's rate is linear, until you get near coil bind. So you can go lower by as much as 1 1/2 - 2". Pre-load is adjustable as well, but....because the system has a single spring nut, pre-load will affect ride height. In most cases you want to adjust pre-load for road course work, setting corner weights. You can do this with these coil-overs, but ride height will be uneven if each corner has a different weight. So you can set pre-load (corner weight) for the track, but will want to set it back to "street", or equal pre-load per axle when you leave.
  14. What we have found is that you CANNOT use the later PCM (2013 +) to run the VDO throttle body. The VDO is brushed, the Magneti Marelli is brushless. So far on the test cars we've seen no issues using the earlier PCM (2012 -) to run the Magneti Marelli.
