I took this from another post i made a while ago about the seemingly slow spool on a 1.6
I have a 14b with 1g manifold on my car. The engine is a completely stock 1.6 with 200k miles.
I have a full 3" exhaust and custom small stock fmic off a mini cooper. Im running between 13 and 16lbs.
I feel its pretty decently tuned with megasquirt on speed density.
Im no expert and its my first and only turbo car but I feel that even the 14b seems kinda laggy. By looking at datalogs boost starts at 3k and full boost by 4k if you time it right on the street. By timing it right i mean hovering at the boost threshold before you punch it. If you floor it from well below the boost threshold full boost comes later at 4.5k or even 5k. The 1.6 seems pretty weak before boost kicks in so that prolly makes it seem laggier? Definitely laggier than the stock 11b. The car really seems powerful under boost though way, way more power than stock last year. The front tires will break loose a bit under full boost and rpm in first gear now. I have no idea on power level but I took it to the strip ,also a first, last month and my fastest time was 16.3 Which really put things in perspective for me after all the reading and learning ive got from this site.
Ive never felt the difference of a 14b to a 16g on any car but i would say for me any more lag wouldnt make it very much fun on the street any more. You would have to be all staged ahead of time with your rpms up everywhere you go to get any power when you floor it. Which is a little inconvenient on the street. I could be doing it ^^ wrong though too lol.
Hope the info helps any.
