#MAKE TURBO SPOOL SOONER INSTALL#

Spool is (or should be) a direct function of EGT and volume of exhaust. Hard to measure turbo RPM - so I guess boost (MAP) would be the go. Holmz Posts: 521 Joined: Fri 5:19 pm Location: Australia and the USoA I even find the lag of some DBW n/a cars distressing. What sort of car and application is it for? Knowing the steady state performance would likely help a lot here. In practice this can be difficult as the steady state tuning ignors the dynamic nature of the engine, and at some point you want to switch from putting energy into the exhaust to putting energy into the crank. For a track car it might be possible to have the power linear with the throttle position, so that mid turn you are spooling. For instance for autocross/gymkhana you would not want to give up a lot of your forward motion in favor of turbo spooling. I was doing this - I would want to understand the steady-state performance, and then select a strategy for returning to the boost condition separately. I would probably bet on 'advance it' - by have no idea. I would not think that the intake cam would matter a whole lot at low RPM. That is one in every category you mentioned that I understand. As it must be going somewhere, I would suspect that it would be going into the exhaust. But you would be giving up a lot of energy (fuel).Р”Р€) You can also retard the spark which would get less energy out the crank. At the bottom of the stroke the temp back to where it started.Р”В«ottom line here is to advance the exhaust cam to get more energy into the exhaust and less out the crank, by opening the exhaust cam earlier.Р”Тђ) To increase the volume, you need a WOT. The higher the compression the higher the temperature in the air above it when it is at the top. (But try not to destroy the engine)Р”В¤)The EGT is also influenced by cam opening position. I think that the curve has high EGT both rich and lean of lowest EGT (which it would have to have from the lowest point of EGT), and I recall, or imagine, that the lowest EGT is not far away from the best BSFC.Р”В«ottom line is to adjust F:A to give a higher EGT. I have labeled the following by your topic #Р”РЋ) At a fixed speed the F:A ratio influences EGT. You want both the exhaust volume and EGT as high as possible to get the maximum amount of energy into the exhaust, which in turn (pun) spools the turbo. So I have zero real-life examples, All I can offer is theory.

fueling, ign, injection timing, VVT (both IN and EX), DBW?Р”Р„ny real life examples are welcomed as well.Р”Р‡irstly I have no experience with this, When I did a turbo install it was all home grown, with no ECUs, and just a carb. Just as the question states what strategies in mapping can help spool the turbo sooner using only engine management system controlled parameters i.e.
