Mike - the only thing I'd note, I've read posts from reputable folks on the sites, that port matching to the 1250 on the bottom of the port may not be necessary, and may actually hurt you. Matching the sides and the top will help the 'straight shot' to the valve; but opening it up on the bottom my hurt you. You may want to research it some more, but based on my limited knowledge, I'd gasket match top and sides; and I'd only remove enough material on the bottom to get a good port match; I wouldn't take it all the way down to the gasket opening.
Michael--That was my plan. I heard a while ago about the bottom of the port. I am just doing the sides and top so they match or close to a 1250. Thanks for the info though.
My suspension is good. Steeda aluminum uppers(adjustable). Lakewood lowers. Koni adjustable shocks. Torque boxes welded. Roll cage and full length frame connectors.
You will not be able to run the 4" AFM power pipe with a C&L meter, they will not read correctly. You will need a 80mm Pro-M as they reccomend. No AFM pipe is for use with a C&L meter..... otherwise looks like a combo that will make good torque down low, carry the HP to around 5000rpm. How much compression? Your going to need a little more for 11.60's IMHO.
Yes i will need more than that for 11.60s but i should be close to the 11s for the spring anyway. Its a start. About the pipe? Wonder why. Are u absolutly sure.
100% SURE, it will not work call AFM and ask. A MAF is not a MAF since a C&L reads different then a Pro-M. I tried to stick my 76mm C&L in the fender and it was very bad, moved it back to the stock location and it was fine. You can stick a Pro-M on the ground and it will read just fine.... I ran the 4" AFM pipe and 80mm Pro-M AFM powerstack filter, nice combo
Since it is in the fender color will not matter www.pro-flow.com has the 80mm colored meters on sale $250...hard to beat that price.
rick91gt----just talked to the guy i bought the pipe from. He said he was using a 73 mm No problems at all. Its the 3 1/2 also not the 4 inch.
You have the 3.5 pipe that keeps the meter closer to the stock position, I'd call AFM and talk to them. They told me it would run run properly with that pipe and my 76mm....I went HV 4" pipe and 80mm and it ran much better, smooth and pickup'd a little in the 1/4.
Ok...so the 4 inch has a different MAF location than the 3 1/2. Ive heard that you can rotate the meter around for smoother idle. Could be i dont know. I think i will try the c&l and if it dosnt work then i will get the pro-m. Is 80mm to big for my combo or is it just right? Anyway thanks for your help. happy new year!
80mm is fine.... I just saw on AFM's site that they say the 73mm Maxflow will work with the 3.5" pipe. 3.5" pipe 4" pipe
Ya thats what mine looks like. I should be good to go. Actually a few people have told it reads better with the c&l the closer you get the meter to the TB. This also could be BS but i am going to do the TRIAL AND ERROR thing. It may work it may not. We will see.
