Plenum Idea

[crazyace]

Heck Sean, I gave that Snota intake away a long time ago when I got a whole 93 Diamante 3.0 for free.

[Ondonti]

still interested in if the 2.5 rails really work with ford injectors. That would make life super easy for me.

[Avenger]

Fricking hell, now I don't know what the hell these rails are. I looked under the hood of a bunch of Avengers and cloud cars today at the yard, and they all have those square tube fuel rails. The ones I was going to use are round castings, they are big beefy things. The Ford Motorsports 30lbs injectors do fit into them, but they are pretty damn snug, moreso than they should be. It seems to be overly compressing the O-ring, so that the injector material seals it, not the O-ring. I'm wondering if maybe these are from the Diamante or Sonata. Or even they could be 95 Avenger rails, they used a different fuel system for that one year. I'll try to get some pics up, maybe somebody else will recognize them.

Lord, I think I need to start labelling things when I pull them....

[Boogieman142]

so,anyone know where i can get a stealth lower, the sonata one seems to be too small.

[crazyace]

Junkyard, Ebay, or car-part.com are all good sources for them.

[irocelectric93]

I checked Car-Part.com and they seemed to have quite a few stealth and Diamonte lower intakes that i guess would work...but they seem sort of pricey. Not all of them though....

[Ondonti]

bah sean, you know you dont want that rail for yourself ;)

I've got a complete Diamante upper, lower, fuel rails, and 21# injecotors that I most likely won't be using. PM me if you are interested.

can you get me valves too?

[Ondonti]

You dont want them.

Ferrea decided to raise the price from $18 to $30 per valve for absolutly no reason. That is for the highest quality valve of course which most people probably would not need. Supposedly they would do cheaper material for ~22

Im very pissed about this.

Are these oversized valve with a 5 angle job that your trying to get, i dunno whats wrong with just getting the stock ones with a 5 angle and save the money, i guess i never read anywhere why you need these

[Ondonti]

because the intake valve is way to small. I dont think its possible to increase intake side flow greatly on the stock valves. Ive never seen anyone get much of any increase on the intake side unless they start doing some crazy stuff like ED is doing.

+2 intake and +1 exhaust. 70 hours of porting in the heads, chambers relieved for the oversize valves. Im not putting crappy stock steel valves in to try to hold 700-800whp.

[roguetrip]

so what kind of springs, rockers you gonna put on to hold that power? Are you balancing the crank and disabling the rev limiter? 8k rpm here you come

:) If my flow bench is to be believed, flow is up at all lifts 0.05"-0.40". Peak flow went from ~185(stock) -> 204-205 CFM (intake) (ie. 19-20 CFM, aka ~10%) with the stock valves... Port volume is down slightly

The exhaust side is almost done. The reshaping is pretty radical! Port volumes are WAY down (I don't have the numbers in front of me but roughly ~20-25% smaller) High lift flow is about the same, but low lift flow is WAY up.

For those that don't know, this is a good thing. Low lift is when you have the initial blow-down of the cylinder. It is also when you have overlap between the intake and exhaust. If you don't have good low-lift flow you will have reversion (exhaust going into the intake... )

While I would like to see high-lift exhaust port flow bench numbers higher and I could probably get them higher, I don't think that would help engine performance. (probably would hurt performance.) I have shaped the port based on a desired cross-section area (CSA) pattern to obtain the proper exhaust velocity. My flow bench (and most) can not duplicate exhaust flow velocity, thus flow bench numbers do not accurately reflect engine conditions (air velocity and valve opening and closing.)

I think the 3L has reversion problems... (black intake runners is clue 1) Hence the tulip exhaust valves (improves low lift flow) and the fairly modest cam. Thus I am more concerned about shape and CSA and less about peak flow numbers... In an engine, I think my ported exhaust port will easily out perform/flow stock.

Right now I am going back and making sure everything is the way I want it. So far two intake ports are showing of some turbulance issues (despite good flow numbers....) I think I know the cause, just need to find the time to fix it...

Hopefully the heads will be sent to the machine shop in the next week or so. Once installed on my Voyager, it will be dyne time. :)

Lots of information, hopefully I didn't confuse anybody...

Later,

Heck yeah...keep the info coming! I can't wait to see the finished product! I sure wish I had the time and such to do what you are like that! I want to...just can't...:(

Oh well...keep up the good work and keep the technical stuff coming, *I* understand what's going on!
