Flow numbers for my TIII head!

[turbovanman²]

Gary's site lists his flow numbers at 10", mine were done at 28" and are almost the same as his. I had it cleaned up, some minor porting, new valve guides and valve grind. He said my valves should be replaced as they sit low and if I ran some new ones, would pick up some nice flow. All I say is turn up the boost, He also mentioned the difference or ?, can't remember is 80%, which is good.

what is it at .335 or whatever stock lift is?? Pics of the flow sheet?

[RoadWarrior222]

c'mon now, quit with the teasing, bolt it all together and fast forward to the bit where you get immortalised on a plaque at the strip... for the longest oildown.

flows better at low lift, .200 and lower than my Masi head. But from there on up the masi head outflows it. Did you do a test with the manifolds on?

[turbovanman²]

No flow sheet, he quickly did it after work, no manifolds either. Stock cam lift is .335"

Masi's flow better than TIII heads,

This is from Gary's site at 10"

Lotus 16V 244 cfm 182 cfm 350"
Maserati 16V 237 cfm 213 cfm 350"
Neon DOHC 237 cfm 195 cfm 350"
Swirl SOHC 156 cfm 135 cfm 500"

I have flow sheets for mine at 28" of water with and without manifolds. Also comparing it to my Ed Peter's 8v head I had flowed as well.

My flow #'s at simon's lift since mine was noted every .050" instead of every .100.

The head is bone stock with mid 80's to mid 90's thousand miles. Can't remember the exact mileage on it. With the manifolds on I drop 8-15cfm on the intake above .350 lift but the stock cam only goes to .315. The exhaust is wild as with the manifold on I GAIN 8-15cfm from .200 up!

I can't wait to have it all ported and a big plenum on the intake with the oversize valves and get it all flowed again. Cool thing also is I can get cams up to .474" of lift. This motor is gonna rock.

Gary's were flowed at 10 inches but were corrected using a 2.6 conversion.

Nice numbers for stock.....

I don't think .474 lift cams will fit through the bores. Might want to take some measurements as to what will fit before you go wild....

Considering the amount of time spent on mine and the worn valves, I couldn't be happier,

Thanks, speed reading and saw the 10" at the bottom paragraph. Paint fumes are making my head spin,

I think he was referring to his Masi head. Those have caps to hold the cam in so the big lobes shouldn't be an issue.

[2.216VTurbo]

...Still a little issue with those cams, well two actually. First, the head has to be notched on either side of the buckets so the big lobes dont make contact as they come around. Not such a big deal, I did it to my last Masi head I built 'just in case' I want to run the huge cams Secondly and probably an even larger drawback for me is the motor is not 'breaksafe' anymore with the big cams Sure would hate to lose a whole motor for a relatively minor mishap like a thrown/broken cambelt...

My ports look like this-

[ShelGame]

The VolEff curve should look like this (using this flow data and the plenum volume you sent me earlier)...

Pretty neat,

I was about to say that it looked about right, but it seems slightly to good... hmmm.

What do you mean by that?

[ShelGame]

I was about to say that it looked about right, but it seems slightly to good... hmmm.

It's actually only a couple of percent better than the stock T3 VolEff curve. Assuming I extraced it correctly from the T3 code, which isn't exactly straightforward...

Masi FTW!!!

Masi FTW!!!

Nah, TIII are hard enough to find parts for, let alone Masi's,
