Koncepts ¯ Member # 5179 posted                              I agree with Red00GT. The 70mm for an N/A car and the 75mm for a forced induction car. On an N/A car, I see that it's pointless to get an 75mm car because there is really no gain. But, they should both work fine. If you plan on boosting soon, go with the 75mm. -------------------- -Single T62-2 Turbonetics Turbo- www.APEXMOTORSPORTS.com www.HELLIONPOWERSYSTEMS.com Posts: 322 | From: San Jose | Registered: Jan 2005  |  : wilit Mustang Messiah Member # 3367 posted                                 Yep, 70mm for a car with a few bolt-ons. 75mm with internal work or forced induction. Reason is, the 75mm will slow the air velocity entering the intake. You'll gain more at the VERY TOP end (5800-6200) but you'll lose too much low end torque due to the decreased air velocity. -------------------- "If a man hasn't found something worth dying for, he isn't fit to live." - Martin Luther King Jr. Posts: 4793 | From: 37.78514° North 122.40100° West | Registered: Oct 2003  |  :
