Hmmmm...Trickflows won't do 280cfm intake???

Think he might have been talking about out of the box stuff.. My out of the box All pro's only moved 256cfm.. W/ a lil rubbin' they pulled 342cfm.. w/ a bit more to go... But in the price per hp issue i think personally you can't go wrong w/ a Trick Flow head, or even a LE/AI LT1/4 head either.. They're plain old just kickin' *** nowaday's..

 

^agreed. When you see some of the newer LE/AI stuff doing close to 280cfm intake, it's impressive. He said the race ready comp ported AFRs though, that's why i threw in the AI ported chart. Sh*t, Lloyd did a set of LT4 heads (stock) for someone on here a couple of weeks ago and they put like 302cfm intake. These days i just don't see the AFRs being worth the money. And, like your setup, for that amount, you can definately go a better route - All pro's, brodix, etc.

 

Loyd done my porting on bare trick flows i sent him. Valves are 2.08, 1.625. I been aiming to call him and get the flow numbers. Sure would like to know what the flowed.

 

Also depending to the flow bench. SF-1020 gives very conservative numbers.

 

Not out the box. IllusionalTA is right - my AFR210 Race Readies (their cheapest porting option) flowed 280 cfm with no modifications.

I hate to bring this up, but we've benched some of LE's stuff also and came up shorter than his numbers. Not saying that he's lying, just that the SF-1020 reads a fair amount less than his bench. Never checked the AI stuff and I don't know what bench they use. The SF-1020 has rarely been over 300 cfm. We're talkin' a $4000 set of LS1 heads on a 4.125 bore does 315. Put it on a 3.9" bore and your back under 300 cfm.

None the less, if you are gonna compare offerings, you gotta compare ported to ported. The race ready is not an "as cast" peice.

 

I am curios as to what a set of the AFR 210s do on a full port job, got any numbers?

 

Flow benches are like dyno's nowaday's.. That not really sufficient for people to compare one head porter to the next unless they're done on the same bench same day type of thing.. I can see someone's number's being lower than the next by maybe 5-10cfm from one bench to the next.. But if we're talking 20-30 then we have issue's...

 

Race Ready from what i have seen is ported yes.. But it's more like cleaned up.. out the box stuff.. If you wanna compare a ported trick flow it's more like comparing it to a comp port afr or even one step further and say a hand ported set.. Ask AI or LE what they get out of a set of 210's they'll probably tell ya 300 or so cfm maybe peaking 310 or so.. I know the 227's don't go much more than 320ish......that all being on a stingy bench from what i have seen..

 

On the AFR site, it lists the 210 race readys as doing 275cfm intake and 220cfm exhaust, good numbers, and the competition package jumps to 297/230.

BUT these numbers are on a 4.125" BORE, and WITH 1 7/8" exhaust pipe. While I am not saying they aren't a decent head, I sure think the TFS heads can get you close, with less invested.

And for the original poster I think that is the point. His builder said the TFS heads were crap. I just don't find that to be the case after having seen a couple myself. I still think a full custom port job on the 210 will probably outflow a full port on the TFS heads, but not by alot I don't think, and when it comes down to cost/performance, personally I would go witht the TFS heads, and then something else, like all pro's, or some converted gen 1 heads.

Having said that, I have seen quite a few people make great power with the 210s (with custom porting) so everything is with a grain of salt.

 

That's actually an error on their site. The title of that chart says "203 cc", not 210. The 210 Race Ready's are advertised to flow 285 cfm on a 4.125" bore. As already stated, mine flowed 280 cfm on a 4.030" bore and 218 exhaust with no pipe.

 

You're kidding, right? When you buy a set of AFR's, you get Race Ready porting. That's the whole point of paying extra for AFR heads. And, since they're CNC'd, you get the same thing in every port, every set of heads. If you buy Trick Flows and pay to have them ported, then the flow will depend on who ports them and how much time they spend. I'm sure if you spend enough on the Trick Flows, they'll outflow the AFR's, but that's true for alot of different heads.

I guess if you really want to compare unported to unported, you can get unported bare AFR210's for $1039 and unported bare TFS 195's for $919. Price gap closes quite a bit, doesn't it? I have no idea what these heads would flow, but with a 15 cc bigger runner and larger valve, I'm betting on the AFR's.

Nope, those "BARE" non ported AFR's don't even come close to being 210 or flowing anything. If you saw them you would understand.

The TFS heads out of the box OTOH you can actually run if you wanted to, but at $950 a set why not port them? That works out to the cost of the AFR Race Ready heads or the Comp heads if you pay that much for porting.

Why everybody started to hate AFR ? I saw lots of company changed their package from AFR to TFS. Golen, Ai etc.. Before I decided to get AFR heads I made lots of research here and I waited 16 weeks for my 210cc AFR competition heads, and now I read these.
