haha, good number with 320...porting the intake isint exactly a bolt on but any non believers already agreed that 300 at the wheels is very possible with bolt ons, but above that is when it starts to get difficult. may I add that you have the best CAI/MAF for those cars as well as a ported intake! anyway who cares, I dont as long as I keep walking all over LS1's...
on with a new topic eh haha
Oh and do you feel the place you see the most gains on these is from a proper cai and exhaust?? What exhaust set up performs the best, setting aside the sound, because I already have the best sound
heres my 99 cobra dyno sheet,it only had stock type k/n filter and long tube headders with no cats,,,since this dyno i added 62mm TB ,,pulleys and 3.73s,,just havent dynoed it again,,,should be 300 rwhp i hope??
third pull was the best..no cold air kit or computer tuning..
