[QUOTE="Jman271, post: 705601, member: 25310"] Hey EG, thanks for posting on here. Well, I kinda firgured that out along the way now, but I just kinda loaded the software in at first and expected there to more more info up front on values, dimensions, etc,,,,this PC porting thing is soooo cool though! Basically right now I am shooting for a BMEP of about hi 150's for a 03 125sx @ 11k. It should work out to be about 33+ HP at the rear wheel which is makes that almost bone stock. But I just want to see what the PC says for info on TA for ex and trans. The values for corner radius is screwing me up b/c there is no real "radius" like middle of a circle out to edge so I am entering "0", is this right? B/C the ex shape is oval,,,right now I have the main trans opening 1st, secondary, then rear boost, all w.i a few mm's of each other, starting @ about 41.50mm and working to about 43.35 mm respectively. Squish is @ 1.10mm, 7.5 cc head w/ about a 7mm band, ex is @ about 27.30mm from TDC. Durations are in the hi 190's for exh. Also, it is hard to measure the choke point s on sub's, @ the liner they are like 10mm wide, but then slim down right away, so I am trying my best. Thanks for posting back- Jman [/QUOTE]
