Dart 225cc Dyno Results Inside!
Dart 225cc Dyno Results Inside! Futral Motorsports just told me the car put down 471/415. The heads are box stock, milled .020 and 2.055/1.60 valves. The FAST 90/90 intake manifold was port matched.

Was this a speed density tune or did you tune using your MAF?
I bet leaving those big 225cc intake ports as cast really helps produce a better air/fuel mixture for the small 346 engine.

Stock short block, 78,000miles, stock MAF, 30lb ford motorsports injectors, stock rockers, no dyno tricks. Meaux racing flowed the afr 205cc heads, the dart 225cc heads and found the afr flowed 280s and the dart in the low 300s. Not bad bad for saving quite a few hundred dollars.

Are you going to state the specs of the cam, or are they top secret.

If you look at Dart's spec sheet the dart 205's flows better than the 225's up to 0.500 where the 225 has 5cfm on it. Exhaust flow is the same.

Bottom line here is that we advertise accurately and guarantee our flow numbers to be plus or minus 2.5% which covers most issues in a production environment. If the owner of those heads would have contacted AFR we would have either improved his current heads or replaced them at no cost assuming we validated (on our equipment) that the flow numbers were indeed soft. I urge all of you to contact me personally if you're ever in such a position.
Let's keep this thread on topic and find out more about the Dart headed combination which looks very promising...
Thanks,

the intake valve is a 2.05 i have a set of the 225's waiting to go on my car. I hope for 430rwhp when i put them on. I have a 224/224 .576/.576 112lsa crane cam. I know 430 sounds high but a man can hope right.
