Stage 6 vs trick flow

[twayne24365]

So my uncle called me today and said he's thinking of buying a set of trick flow heads, his motor currently has a set of stage 6 heads that flow 317@.600 lift. I just don't think he will gain much performance switching to trick flows that don't flow much more air, any comments?

Comments?? How much will he take for the stage 6 heads !!

The key to making more power is not max air flow but the total area under the curve.

That's true, plus the fact that he's forcing air through it with the blower.

And if he does want to sell them I'll post an ad on here for them

Just joking , I wouldn't be able to afford them.

Sure you could. There basically worth less than the trick flow heads. If he wants more than the trick flow heads, just get the trick flow heads and let his collect dust.

 

[twayne24365]

Yea idk how much he'd want for em, they can't be worth much

The Trick Flows are a better head overall from what I have seen & read. Stage 6s were never that good without a ton of work and the Trick Flows have a better chamber and finish right out of the box. Whether or not he would pick up depends on his setup. You need to post a lot more info - like everything about the engine and car.

The heads are almost a moot point with forced induction. The only real difference will be that the Trick Flows are aluminum and have that heat dissipation thing going for them.

 

[twayne24365]

Well his stage 6 heads are aluminum....but the rest of his combo is
496" 440
7.5:1 static
580 lift 265* solid blower cam from Steve Morris
M1 intake with csu blow thru carb
F1 procharger he spins it hard with 18lb boost through the traps
He runs c16 fuel with snow performance water/meth blown into the hat
727 with brake and 3500 blower converterconverter
Dana 60 with 4:10s
14x32 slicks
3600 with him
Best so far is 9.36@142mph

Also dynod at 676hp to the tires, that was before he actually put a little timing into it, that is now sorted out with an msd distributor and msd boost timing controller

 

[RustyRatRod]

I don't think he will see an appreciable difference in a blown application. JMO.

 

[twayne24365]

That's what I thought, unless he went to a victor m/w, b1/ or some of the like that would get him into the 350-400 region....

For a blown gas engine big block mopar the cooling of the two center exhaust ports is the limiting factor. They will get hot and then those cylinders start detonating. You can get big hp on a dyno for a few seconds but on a quarter mile at the big end they just get to hot. I know this post is getting old but i just had to add my 2cents worth.

Makes sense, he burned up #4 piston and is always fighting high egt.... He added a snow performance water meth kit and that didn't seem to help.

Straight methanol. The fuel for boosted engines. Burns cool. Make it easier to work with those paired exhaust ports. My engine will heat up maybe 30° in a quarter mile pass.

 

[MidTexCuda]

wow I would have expected more from that engine HP wise. That f1 will make more power than that and the boost is only about half way. Is this a street car? How much work has been done to the heads?
I don't think he is spinning that blower enough or there is some belt slip. Is he tuning with a wideband? may be time to go to a a/w intercooler.

 

[twayne24365]

I thought it should make more as well....and as to how much is done to the heads I have no idea, he just said they flow 317 @.600...I know he has a smaller pulley in it to spin it harder but I'm not sure on the size

 

[twayne24365]

Also yes he has a wideband, and I've been telling him for years to get an intercooler

 

[mguner]

Waiting to see a blown poly setup which will have not "hot spots" in the heads....

 

[hangn0ut]

Wide band tuning a blown gas motor can be tricky. What a/f to shoot for? It needs to be rich to cool things down. Even with an intercooler. And egt's can be all over the place. Will let ya know when you drop a cylinder though. Gas has a narrow tuning window. Blown even more. High boost better be right there and with a carb, that takes mad skills. Gotta admire those that do it.
