My number was done at the Texas Mile so we were able to compare nearly two dozen other setups on the 0-300 run over the last few years. It was pretty cool. There is an interesting data overlay floating around somewhere from half a dozen cars that made pulls on the same day at the mile. Can't get much of a better comparison than that!

Well I can comment on this because we have done 18g and 20g installs. My own car was 20g, from 911tuning and Protomotive. On a tiptronic with an MKB upgraded box.
We have an 18g in the shop as well that is billet 18g. The 20g is not billet. The 20g kills the 18g billet - it is that simple, real life results.
There is a little more lag in the 20g (that was fitted with full y-pipe, 5 inch Ics, injectors, the works basically) but as soon as you are on it, the 20g pulls much harder than the 18g.
18g works well at 1.35 on pump, and on race gas 1.45 is fine. However, 20g can run 1.4 on pump, and 1.55 on race gas.
There is very little difference between and 18g and 20g at 1.35 bar, because the 20g does not wake up at 1.35 bar - don't get me wrong it is quick, but as soon as you take it to 1.45 bar + it is a different animal.
On a slow surface (worth 2-3 seconds in time compared to other places) the 20g car runs 200 in one mile in 28.25 seconds, with 300kph in 22.5 seconds.
The real advantage with the 18g is the fact that you don't have to do y-pipe etc. The 20g certainly costs more to do because of additional hardware.
The 20g above has a 6.14 in the list that was done with full weight car 1585kg + 2 person + 3/4 tank. I have run 5.85 before.
It really depends on what you want. I have moved on now from the 20g and in the middle of bigger engine build with bigger turbos etc.
I have taken people out in both the 18g and 20g. Customers immediately see the difference.
I would say there is 0.5-0.8 difference in 60-130 time between the two, maybe a little more. That is on pump with full weight car etc.
