A simple poll. Who here has cut their intake off for some intake porting and a aftermarket intake, wether it be a sheetmetal style or a trick aluminium style like the "Hellmann"?

All the post needs to contain is:

-Yes/No

-What type of intake

Cut them off , makes it a bit easier to port.

We make ours out of steel.

how about a poll that says would you cut off your intake? cause i know i would and port the head
 
i have not because the benefits are not there until you get in to the 1000+ hp range too much porting and you lose your air velocity and that is a bad thing when it comes to turbo charged engines especially big single chargers it is not a neccesary thing to do at this point.
 
Cut it off and used a zzfab, 3.5 inch side entrance, 3.5 inch piping. The porting's worth it IMO.

I take it you have not looked at the crap casting in these heads. Both intake and exhaust ports are so choked down you can barely drop a nickel down the ports.

Glad to know someone else knows the truth

Port the exhaust side and clean the intake side up and that is enough.
 
i would rather have volume over velocity any day. the higher your velocity the more drag created at the surface of the intake. even just polishing with no porting of the intake will improve flow. the smoother the surface the better the flow. also you fix the issue with #6 cylinder not getting the air flow
 
i have and there is alot of potential there it is just not a neccesary thing to do for me rite now money well spent else where, whin i ported my bowls the seats on the intake side petruded into the bowl .080 of an inch thats like hitting a wall for the air alot was gained there even.

I don't agree with that at all, I found after all the head work, it was WAY more strong off the bottom, spool was there sooner, and way more on the top. WIN WIN as far as I'm concerned, mind you I'm up there so maybe thats why it seems more apparent.

But $ for $ its not going to compare to a base mod like a set of twins ect.

Icing on the cake, you bet.
 
While it's a little ridiculous on a stock motor or even a motor that make 400 at the wheel. Guys that more or want to make more greatly benefit from opening up the the flow of air into the numbers 1 and 6 cylinders . On a 12 valve it's one thing on a 24 valve it's an entirely different story. 24 's are so choked down the boost numbers are throught he roof. It's all about volume of air .

More air pushed in means more out (spins the turbo)
 
It was worth it in my opinion. Sure, you can crank up the boost and ram it through.

Or, you can open things up so it will freely get air without the drag caused by high drive pressures and sorry flow paths.

that is another factor to the polishing and porting the fact that the turbo does not have to work as hard to move the same amount of air the charge air is not heated up as much due to not being compressed as much. the boost is a result of the restriction of flow. if you remove the restriction then the air will flow the same amount without the need of the high pressure. sir heats up when you compress it. go look at a thermodynamics P-V diagram.

IMO if the coin is their do it, as said the smoother the better (as in many cases). Opening up of the doorways is benificial also. I am not here to say it is going to gain u X-amount of HP cause I have no evidence but u can bet that it will not hurt u so their is only 1 option left. Another thing as was said it might not be $ to $ the best mod. but if u went to by a loaded Caddy for example with all the bells and whistles would u drive out on 13" steel rims? I think this is a later mod in the quest for all out performance but I DO NOT think that once u reach this point that it should be overlooked.......
