How much boost?

**Shane@DBPerformance** · 04-25-2006

A bigger turbo will heatsoak an intercooler even faster than a small turbo. A small turbo will put out high temps at higher boost, due to a less efficient compressor wheel, but they don't flow a lot of air. 600CFMs of 190 degree air from a bigger turbo with kill and intercooler much quicker than 275CFMs of 230 degree air. The 14B is just big enough to be dangerous. With race gas, you can run the 14B well into the mid 20s and it keeps making more power/torque. The T25 is so small that it can't max much out or hold over 15-16psi once you get into some decent RPMs.

And this gent is talking about on the stock SMIC. I know people have pushed their 14's into 11 seconds, with HELLISHLY good tuning. But with the stock system, 16 is about the best you can do before heatsoaking. At least this time of the year. Winter you could do better, if you tune for it.
