      Gale contact me, I have 3 ideas 💡, about reducing the turbo lag. I am a research associate ay a major University.

              Any mention on why the 7675 turbo has dual air filters? Anybody else notice that on the video footage

                Yes. The single MAF sensor maxxed out at 60 lb/min. That's why there's now 2. So it can now go up to 120 lb/min. I'm pretty sure Gale said something about this in the video

              So, the precision turbo is better.

                Gale, the bigger turbo is unsurprisingly more efficient at higher RPM's and higher loads, but what about low loads and low engine speeds? Wouldn't a big turbo that is barely spooling up almost act as more of a hinderance? And if so, roughly what engine speed/load would be the cross-over?

                  I'M notn sure why Gm doesnt have Mr.Banks build THEM a diesel for mass production in their trucks. Imo Duramax is one if not thee Best Diesel on the market today. Sure Cummins is good, and Ford's well they speak for themselves, garbage.

                      Just going to throw this out here to see if it's a really stupid idea or not.
                      My thought is that turbo lag could be eliminated by adding more pressure to the exhaust manifold on demand. Perhaps a three quarter inch pipe feeding in air at 75 psi electrically activated when you mash the throttle from low rpm? The tank for this can be refilled by an electric air compressor over time 5- 15 mins for a larger tank or an engine driven compressor as is used in trucks.

                        A novel idea for drag racing... but for daily driving or sustained racing the amount of air needed would require you to turn your truck bed into a giant air tank. And, you'd need an air compressor the size of a small engine to fill the tank at a rate that would replenish the air faster than the turbo is consuming it.

                                How does one double up on the maf?... Is it just plug two into the wire harness/intake or do you need to program another one in as well

                                    How about an explanation of compound, and twin turbos, in this detail ??? Amazing, diesel power!! What is your opinion of the old Detroit 2strokers?? 6v71, 8v71, 6-71, 6v93, they sound like the race engine of the diesel world!! But can they make power? Like a 6v71, with twin turbos added to the mix, I know they are not as common as they used to be, but even the 4-53's sounded mean!! Great video Mr.Banks!!

                                      What would happen if you had an adjustable turbo bypass for the stock turbo. This way you would reduce back pressure on the intake flow to the cylinder but kept the proper pressure to the turbo through the acceleration range? Does this make sense?

                                        Could you make the exhaust side a little smaller say 70mm happy between the stock and the 75 mm that would spin the turbo up faster and give more more rpms to the turbo witch would I turn spin the intake side up so you would get more volume at lower rpms?

                                            Twin turbo with one of each to gain the benefits of both.

                                              It sucks that diesel guys watching this will latch on to the brand names used. Precision makes stuff for high pressure ratio, and Borg Warner is more/better coverage in compressor design. Too bad Banks isn't using a BW of the same size.

Thank you mr. Banks for sharing all your knowledge with us from your student Robert Johnson always following and watching.

                                                          Must be factored in the data cooling the fuel at the injection. By 10° will make a big difference. Run the fuel through a transmission cooler with a fan after positive pressure pump....aka...fass pump. Lowering the temperature of the fuel would like to see same data but with the lower temperature fuel......🤔

                                                            Before you blow that motor up you should build a compound turbo set-up with precision turbos and see if you can overcome the lag along with how that effects heat and fuel economy. Would be interesting to know.

                                                              With that said, I'd love to see a gen2 Garrett and a larger performance Borg turbo compared to this precision. I feel like there may be a bigger compressor advantage with the GT or Borg to go along with the turbine improvement.

                                                                To reduce turbo lag would a system with 2 turbos be useful. Say, one being 1/3 the inlet size of the precision turbo , and the other being 2/3 the inlet size. My thinking goes like this, the smaller turbo can spool quicker due to the reduced turbine size. So when you hit the accelerator the smaller turbo reacts quickly giving the larger one time to get up to speed, when it does they would work in unison. If it was necessary there could be a valve system before the turbos, alternating the air flow between one or the other or any ratio in between. Sort of acting like a deconstructed vgt but much more modifiable.

What about everyone else who bought an $80k truck for the real world. What are the benefits on the street? I’ll bet those numbers don’t look so good especially for the investment. Flat out dyno runs do not correlate to real world usability.
