well it's nice to see some others take on this project.

There is info posted here where i did this same mod to a few intake. Take a moment to look it up. Also it would be wise to flow the intake afer the mod and do the final runner porting to equal the flow.
 
Yes I read your posts on it also ...I have a few ideas on how I want to do it ..mainly in the corners I will round it and I will weld a plate to decrease the volume of it altogether..I don't have the capabilities to flow it but hey I have a couple more if I need them ....thanks for the support guys
 
ive not personaly looked at a i/c intake but from what ive read it seems like if i were to bring the volume down and make the roof level with the ports there would be less for the turbo to work ?therefor creating faster spool time and instead of having the inlet split like it does i was gonna do like the champion intake ,were it uses the one side to fill the intake .and round the corners so it has a smooth transtion. thanks george:)
 
plenum size is an important thing when it comes to boost in a non-intercooled application.

a once old rule of thumb for us draw thru guys was that the breathing plenum be 35% of the engines total volume and 50% for the discharge plenum. A large plenum has the advantage of allowing the air to cool and straighten itself out.

if you look to the modern world for examples we can see where plenum tech has really shined. Look at modern high power imports, they have a large plenum the covers each throat the feeds the engine. inside the plenum each throat has a velocity stack on it. there engineering concepts being torn from basic boyles law.

Think of plenum size as a large air/fuel battery. the more the engine can pull from this already available and slighty stagnant mix, the easier it is to straighten out.

and since your fuel injected.... you dont even have to worry about fuel dropout..... take advantage of that and make a big plenum
 
in a crazy sort of way yes.

I dont know if you actually can, but in my OPinion.... i think it would help out alot.
 
Why do you think they made the injecters hit this part off the intake before it went in the head? This is my outher intake....happy new years too guys

The I/C intake have this aswell. I just think they didn't worry about it since the stock inj shoots a very tight spray so it was not worththe effort for the extra machining off the ports.

this is my OPinion
 
Well if you look at the one I have cutt open its gonna have a nice direct spray now....still have a lot of work left on the intake but ones I get setteled in the new house I'm gonna get b usy agin iv been looking into the more air like you said doc .but I will have to do some fab work to bring up the roof basically just cut it off and build it up?

your guess is as good as mine Brother, Thats why i ditched thoughts of trying to improve it. it just seemed better to use a clean sheet start.
 
I did something like this with one i had, but scrapped it because there was a few people that told me it wouldnt work. I had cut the top of it and ended up gutting from the top down, i mean i cut everything and planned to weld the top back on but like i said i scrapped it.
I have an 85 intake that i plan on working on in the future. Let me know how this works out for you.
 
Ok made my way to my buddys shop and got the intake back first is the pic I need to weld the plate on the roof .the 2nd pic is were the zip tubes were I was thinking of cleaning them up very nice and maybe opening up some more for the ports to flow better the 3rd pic is the part were I'm going to put in a sort of gusset so that the air hits and rounds off to a smooth transition like I will round it in the corners so its doesn't just hit the back of the intake and do whatever it wants I want to direct itit myself and on a side note I got 4 fillers 80 percent nice for 40 bucks yesterday. Lol
