has anyone used the dart heads....i havnt seen any flow numbers for the pro 1's but they have the same intake runner size and valves as the afrs. Not sure about the exhasut ports though anyone know..... and they are a few hundred $$ cheaper than AFRs

Some info in the articles section on airflowresearch.com. Afr intake flows 20 cfm more. Didn't read through whole article again but it was mm&ff's.

Kinda depends what method you'd like to believe...

DART claims higher flow figures on a WET flow bench, AFR has higher figures on a dry flow bench. DART's chamber design is a nice chamber as well.

As for cheaper ... I don't know what you'd looking at but in most circumstances a DART is a little bit more than an AFR.

You won't go wrong with either head.

$.02

What I meant was muscle mustangs and fast fords did the testing independently and the dart 225 flowed 309/254 and the afr 225 flowed 331/250, which to me is a LOT more intake flow.

Like Scatstroker said, Dart tests wet flow were AFR and MM&FF test dry flow. Many will say you need to know wet flow to know what a cylinder head will perform like.

You should do very well with either. Some say the Dart can do a little better. Other say the AFR will do a little better. Many say you'll do well with either.

What are you guys saying, dart flows the heads on a wet bench that gives numbers?? Wet flowing is a process that basically introduces a gas like fluid into the air stream going through the intake port and stains the port and chamber so they can see the fuel trail.
There is no flow numbers from wet flowing. What they advertise is wet flow technology, not wet flow numbers. Call Dart and ask Tony yourself!!

My response was poorly worded. Dart concentrates more on wet flow and do not feel that having the highest dry flow numbers will necessarily make a head perform better than another. I think most will agree on that. A fellow who works at Dart went into depth about this on another site. I'll try to remember to post a link when that site is up and running again.

Yes, the numbers advertised and quoted are for dry flow.

Just didn't want people who dont KNOW a whole lot about wet flow to get confused between the two. That's all
