Maximum cylinder pressure of LS1? I am wondering at how many degrees after TDC maximum cylinder
pressure occurs in the LS1? I see most engines are somwhere in the
10-20 deg range ATDC. I also heard somwhere that it takes
2 msec for the spark to ignite the mixture and it to fully propagate so to develop maxium pressure in the cylinder (so spark is advanced with respect to TDC).
I realize that there are many variations going into this but there must be some
figures, say at nominal athomsheric pressure, 70 deg F, 92 octane, 30% humidity etc. etc.
Any ideas or data that has been made available?
Thanks,
Gert
