i'm thinkng of going with 10.5 com pistons, afx computer and 8-10 pounds of boosted. what kind of problems do you think i will run in to

welcome to the board use the search function, this has been covered a number of times. You will most likley run into ignition timing problems.

Depending on how well you build your bottom end is the answer. I run 15psi with 10.5:1, with no ignition problems. Just like ^^^^^ said, do alot of searching and reading before you start throwing out questions. Believe me the answers are there. Using the search about 75% of the time got me through my build.

look i'm not new to the board i just don't post a alot because 9 times out of 10 some one saies "uses the search" in stead of helping and giving there info or there thoughts.. and if every body did use the search there would be no more post. because over the year we have talked about any thing and every thing you could think about for these cars.

This board has been around since what, 1999, 2000, 2001? I don't know. But as you stated, if everyone answered all questions, the info would be here in a years time. Well, This place has been here for SEVERAL years, and has gathered tons of info.

It's all there. The AFX computer is for NA and advances timing, plays with fuel curves, etc, which is bad for boosted on 10.5 compression.

If you can tune it correclty, like DJ, then you'll have no problems with it.

Thanks for the info..

do a search for "hi comp boost" or any related keywords. it has been discussed several times at length.

and yes, if nobody posted then it would be slower, but searching never hurts...esp when you can find it when we have already answered it. when you answer the same questions 10x over you tend to get tired of typing...when all people gotta do is search and read.

p.s. 5 months is new here considering weve been here for 5ish years :P
