Well, Lloyd emailed me my flow #'s for my AFR210's that he finished porting from bare castings. I believe he used 2.08/1.60 valves. Below is a comparison between my original LT1 ported heads he did (when I made 383rwhp/353rwtq N/A), AFR CNC 210's, and my AFR 210's Lloyd did.

..........Lloyd's LT1 Heads..........AFR CNC 210's................Lloyd's AFR 210's
.200........133/92..........................138/112............................143/103
.300........188/132........................201/150............................204/141
.400........233/155........................247/190............................247/173
.500........264/180........................276/207............................281/198
.600........274/191........................288/220............................308/219
.700...........................................297/230............................311/227

I have less than 2k invested in these AFR heads from Lloyd (that includes the price of the AFR heads bare). All exhaust numbers from lloyd were done without a pipe. They should work well with the turbo. Combustion chamber will be 65cc and I havent gotten the size of the intake runners yet.

Wow,
Those things flow great, More did my 195's and they flow good but nothing like yours. 300 CFM @ 600 is great.

Wow those are gonna be bad ***. What did you pay for the bare heads from afr? I was planning on going LE3 heads, but if the price isnt much more I'd rather buy some bare afr's and send those to lloyd.

RealQuick

They can cost 1000-1200 NEW bare (no port work at all). I got a deal on mine.

Those are some nice numbers. What is the finished size of the intake runner?

I have 2 cars at home with Lloyd heads, going back to dyno on mine after Ti retainers and going to dyno with other car that has lloyd head for first time dyno.

bla I can't talk for some reason


Anywho, Lloyd is great!

NICE

Loony

How come the exhausts flow not so much compared to the other AFR's

Is that somthing you do for a turbo?

bunker

Cuz AFR's numbers are BS most of the time

RealQuick

I am awaiting the cc's from lloyd.

Deenasty

how did the exhaust flow get smaller from the stock casting afr to the lloyd ported afr?

Remember the runner volume only tells you a story if you also have the average port length and min cross sectional area.

It didnt get smaller. I showed the # that you would get from AFR's CNC fully ported heads (based on their website info) versus Lloyd porting a set of unported AFR's.

Great number's.. Glad to see some "real" world #'s.. As compared to lloyd's LT1 casting's on his own bench!
