crapola
See ya later
it was a narrow question asking which is better...
F or B for this particular head.
I got neither and the got the typical "TFS1" my buddy has.. blah blah.. TFS1 is a new grind.. blah blah blah FMS cams are 20 years old blah blah blah I spent almost 2500 in my engine and I'm running 13's still blah blah. TFS1 has better duration
I guarantee most of these posters are going with the flow and have no real life experiences with these.. just what they heard on the internet.. Internet mechanics..
I ask a question between 2 cam then get referred a cam .. that I know I do not want ... then get told storys of how great it is.. even though its the only cam they've ever used and its what everybody else is doing/using. That is why I am frustrated..
say I'm immature.. a know it all blah blah to young to understand yadda yadda ya
but I've owned 2 cars that are probably faster then just about anybody in this thread.. probably the only person whos really BUILT a car too..
I got timeslips, receipts, ppl I have raced.. pictures of myself/cars if there is any non believers.. this thread is why I have not been on this site the past year..
I dont know off the top of my head but I believe the TFS cam is like 218/222 and .49x/.51x plainly I dont see it having enough duration to make the power I want off of these heads.. and it is a bit to mild for my powergoals and what I want to do with the car.. so there ya go.. that is my reasoning for not getting the TFS cam or wanting it. My buddy has it on his stock headed car with just a performer RPM intake and rockers and ran a 12.8 @ 106.. faster then some ppl over here at stangnet with 2k+ set ups ;-) so I know it can make power.
TFS made the cam more with stockheads and there specific TW heads more then anything. GT40ps vary from stock heads and TW heads very much to say the least.. check out the flowcharts on a stock gt40p heads and you will see what I mean with the .500 lift.. anything over a .50x is waste with heavier valvesprings and more wear/tear on everything. The extra duration is to make up for the lack of flow and to gain a few up top...
another real life example.. a motor I put THIS CUSTOM CAM into made 311rwhp on this cam with a performer RPM intake and bone stock GT40ps with the gt40p shortys.. not longtubes.. and I would say from how it did on the street would trap 110+ easy.. with some power left in it... (blowmasters, accesorys, pulleys,)
I had the B and F in mind due to its close to .500 lift and over .223 duration on both sides..
must I explain myself more?
