AFR 165cc<TFS TW
Calm down...relax...start breathing...I'm not the one talking BS...the facts are right there if you are willing to take your time to actually research the topic...IT has been proven time and time again that AFR's make more power under the curve than the TW's...NOTICE how I said under the curve and not just peak HP...I do agree that the combination has a lot to do with this matter than the head alone...I have no idea why MM&FF comapre the TW's to the AFR's 185's...YOU can call and inquire about that...It's funny how I'm talking out of the box heads...and then you go ahead and keep saying about a clean up job to the TW's...well guess what buddy...to blend the bowls and polish the chambers and even port/smooth the exhaust for to a perfect 1415 Fel-Pro gasket...that right there will abe about $400.00+...in labor by a reputable head porter and not some nobody with a dremel...Like I said before...just polishing will do nothing...The fact that the TW's have a bigger valve on the intake tells me that AFR must have done something right to achieve the near same flow with a smaller valve and a smaller intake cc...Common sense here...Stick to the subject and don't get all confused...There are different heads out there that will flow better than both AFR's and TW's once slightly cleaned up...i.e...the GT-40X's...I'm talking right out of the box...AFR's will give you better results...is it worth the money? Probably put this in the same perspective as porting or slightly cleaning up the TW's heads for $400.00 more...
YOU are full of wasted knowledge about this topic especially AFR's...AFR 165's come in 54cc, 58cc, 60cc, 61cc...not sure about the 64cc...go to the website and check it out for yourself...www.airflowresearch.com While you are there you can also see the flow number with the emmision legal AFR 165's and the non-emission legal ones...prove me right! I have nothing against TW's, they are a good head but I like the fact of a smaller head making as much HP as a bigger one...I will say this again...TW's have more meat on them if you want to port them...and do flow once ported...Still a very good head for the money...I would really like to know where you get your information from...
