Just wondering how it is working for you. I have 70mm TB and 73mm MAF. Also running the 270 extreme energy cam. If you have the same combo tell me what you think.
Anyone running AFR 165's and the RPM2 intake?

- Start date

The combo (the cam was a 274 xe) was dyno'd in one of the more recent Mustangs and Fords. They never mentioned any problems and showed real strong numbers. Yes, the 185's showed more peak power at the end of the curve, but the 165's had real strong numbers down low and peaked a little faster with more duration on the curve.
I'm not drag racing the car, so rapid torque and power is not a need (though always nice
). As far as the meter... I have not found a good enough reason (dyno numbers) to go bigger. Besides, the RPM2 is not pulling much more volume than original RPM. More, it has better velocity and balance.
If yourdrag racing then you don't really have to worry about "downlow" torque so much. 95% of the race you are at 3,500rpm and up anyways so the "up top" power is what keeps you going along.
I personally would get the RPM to get the best of both worlds in your case. Good flow up top while retaining some low rpm velocity in the ports.
I'm happy with my performer.

.2+ is a good reason to spend $300 on a meter, especially since an RPM II is $550 and you may gain nothing.
It's unlikely you see anyone here with AFR's running a 73mm C&L meter, there's a reason for that. You can take the advice or leave it, but the fact that a pro M is worth .2 over any other is a fact, not my opinion.

Get the heads and don't worry about the meter for now if your car runs fine. Swap that later but address them heads while you have the money
You already have a aftermarket MAF. Now if you feel the need to swap to bigger injectors then go ahead and get a new meter. Pro-M preferabaly.

I'm not disregarding your "opinion"/fact. The motor is already put together like this: 73mm C&L, Edel 70MM TB, RPM2, AFR 165's w/ triple valve springs, 270xe cam, 1.6 Roller rockers, hardened pushrods, and matching lifters, Stock bottom end with 32K miles, MSD 6AL, All this through a build AOD (customized by Lucus Racing)
So the original question was "Can anyone who has a similar setup tell me how it is working for them." I am not trying to be a smart ass. Your setups are waaayy diff from what I have and only wanted to see how it worked for others. And, no I am not the only one with the same setup. A buddy of mine has the same parts, but he is running a 274 cam and " "Stroker" bottom end. (Crank and custom pistons and rotating assem.) His car is very quick and can just about snap your neck in three gears. Just wanted more input for a similar setup. I do appreciate your input, but don't get offended if someone has a different opinion.

Pro-M is gone. Out of business. I've read someone else bought them though. C&L has remained stable. It's all personal preference on MAF's.
Not tying to be a dik, but if Pro-M's products are so much better, why did they crash and burn? You can't argue that one MAF is better because it gave 2/10's better time. Hell you can't even quantifiably, scientifically demonstrate that "fact" with consistent repeatability. Too many other factors. Wind (cross/tail/head), traction (compound, type or ammount of it), car setup, gearing, engine condition, driver ability, etc... the comment of Pro-M always being worth .2 over anyone else if laughable if a joke. Hystertical if serious.
I forgot to mention the 24# injectors and plenty of liters per hour Bosch fuel pump. (very quiet). TJ- thanks for the input on ProM. I did a comparison and tons of research between the C&L and Pro M as well as hp limitations based on the size of the MAF. Everything I found that related to driveability, MPG, and overall performance pointed to staying with a 73mm MAF and I just happened to choose C&L by availability.

Yes I know they are out business. It's called used or classifieds

Simple, just money management. They could have did it better. That doesn't mean their products were bad. They spent to much money researching and developing and didn't charge enough for it. Not enough profit IMO. Doesn't take away from their product. They have a better quality maf configuration. Not made thru "sample tubes" like C&L. Pro-M has a better rep with actual output to customers in running satisfaction. A search will put that out.
I was not downing C&L, I was just making my suggestion to him.
I never said that Pro-M would give .2 tenths (I don't think it will). xp8 stated that as I'm sure you meant the comment to be to him.
Yeah, I had a customer remove his ported Explorer off his AFR 165 car with an E cam and put on an RPMII - and he lost power all the way across the rpm band. Prob not what you wanted to hear though.

This is an extremely ignorant comment. Pro M did not go out of business because their meters weren't any good. They went out of business because they tried to hard to get into other facets of the industry, rather than sticking with what made them famous. People just assume that they went out of business because they werent selling enough meters. You know what happens when you assume, don't you? I would like to see a chart of the money consumers lost by buying a junk C&L meter only to later on sell it at wholesale price trying to unload a useless product.

You have you're opinion. I have mine.
Perhaps you think I made an assumption. But what I said was "products" not "MAF's". I was speaking in wholistic type terms. Their product line as a whole didn't sell well enough to maintain the companies existence. You are correct that their could be mismanagement issues, growth that went unchecked or poor business direction decisions. All water under the bridge to me.
If that one product is "the best" it will rise to the top of the market again.
Pro m is just under another name now.
The owner is physically different, the meters are not.
The same guy does all the programming and calibrations.
Her'es the company, no need to browse classifieds for used parts.

Ever see a store in the mall having a going out of business sale? Then you see the same store in a different location, same stuff, same prices, different name? Same idea.
C&L's are a joke, why do you think 90% of cars 11's and quicker never use them, because as you add power they get more innaccurate, this comes from the mouth of a person that has run many cars on a dyno. C&L's work correct in like 1 of 5 cars, and for every person that has their car run right they think everyone gets the same results.
Only thing C&L does right is make the right contributions to the magazines.
Funny, you pay $200 and what do you get? A piece of round metal with a hole in it.
And 69converted, you can take my word for it or not, regardless it's still true, and you would certainly gain over a 73mm.

I run a RPM II, AFR 165's Steeda 18 cam, S-trim with 3.33/8 pulley combo.
With the Snow kit and SCT tune it put down 540/497
:woot:

If this an attempt, let's not compare N/A to a power adder application on an RPM - apples to oranges
If not...........never mind
