What performance gains should i expect by increasing the compression ratio to 11.0:1 intstead of 10.3?? is there somewhay to find out??? also how would i go about increasing it?



thanks

typcally it raises 5-7 hp per increase. this is based off of my friends neons (DOHC 2.0)

when you say per increase........ what do you mean .1 ??? .5 ??? or 1.0 ???

random can you suggest something.......... i want to stay N/A and i want some major hp....what would be the highest compression ratio that i should use???? what would be the gains.......based on 91 octane....because i know with higher compression comes higher fuel rating

this is based from 10.3 to 11.3...

I just want to know how you are planning on raising the CR first....

Get a CAI, BTB, BIM, have the BIM extrude honed, Do some head work (port and polish), headers and full exhaust, then replace the stock cams, then...if that is not enough power for you...we can talk raising the CR.

As it is potentially the most damaging mod if done wrong...you want to do it last...not first.

Leave it to Random to Needlessly complicate things.

thanks man ...... i am on my way......... i ordered the cai and i will be getting the bbtb soon and headers exaust will have to wait a while though
