this motor is for test purposes i would rather blow this motor than a fresh rebuilt motor, no taking chances here this time.
After i get everthing running good on this motor i'm going to have a special motor built.

other than that i hope it goes well for you. i was planing on dong the same thing then gas went out of controle.

I'm not sure if you're done with the cell install yet, but you're going to want a metal divider that covers it and seperates it from the cabin, otherwise you won't be allowed on any tracks.

Yeah, that's why i said not sure if it's in place fully or not, lol, but I notice a LOT of people just throw them in the back of the hatch, which is against NHRA and a couple of other rulebooks, and a lot of tracks refuse to let you on if they're installed like that, they usually require like a sheetmetal divider to cover it up (fuel lines are ok though, so *Shrug*), just wanted to say something before you got it all done. Is that baffled at all? If not are you going to be using a surge tank at all, and is the other can the oil catch or a surge? Kind of hard to see the inlets/etc on it.

Here is the primary port that I am running on my engine. This is the template I have overlaying a stock s5 n/a intermediate plate.
Here is the template I'm using overlaying the Mazdatrix 6port primary streetport. Notice the HUGE difference in size because Mazdatrix doesn't know how to port 6ports very large.
Here's how tiny Mazdatrix ports the secondary/aux ports. Ignore the little indent at the top of the secondary port on the template, slip of the hand when not payting attention
It's supposed to be flat.
I don't have a comparison shot of my secondary versus theirs, but I think you get the idea. If you haven't seen 88IntegraLS's secondary/aux port, you should. He proved very well and good that there is a TON more port area to be had on the n/a for the secondary/aux.

Mazdatrix's template is conservative for several reasons...It keeps the 6 port sleeves functional, so that immediately kills all those crazy wild ports that you see people make. The primaries on that template are twice as large as stock, but any larger and you run into newbies grinding into the water jacket (ask me how I know). Also, they don't open it as early as the template laid on top to control overlap.
Yes, they COULD be much larger. But you can certainly see why Mazdatrix went in the direction that they did.
I also have to wonder how much those "massivly ported" 6 port NA engines are really improved. I'm sure top end screams, but I'm sure bottom end suffers greatly (primarily due to much more duration and a lot less velocity). I have not driven one of those cars, so I am just making an assumption.
Besides, add a small bridge to the Mazdatrix template and we start to talk...

As far as the template I have overlaying the Mazdatrix one, that is the stage 2 primary port design by Kahren. If anyone recalls, he made 195rwhp or something like that on an s5 NA customer car with the stage 1 version of that port, RB header/presilencer/catback I believe, TII manifolds, and an s-afc. I believe that was it. That was also letting off before redline and before the power started to die off because it was getting way too lean.
88IntegraLS has told me many times the design of his primary port is concentrating on velocity mostly, as it looks so in the pictures I've seen too. As well, he has a huge ported aux/secondary but keeps his aux sleeves completely functional as to control low end. He has told me that his low end feels completely normal still, but as soon as the sleeves open and you hit the upper range it screams. I still need to take a rid in that car some day
Obviously keeping the sleeves functional decreases SOME of the top end potential of a massively ported aux port, but it's up to each individual to decide if they want to keep low end at the cost of a little more high end, or go all out and only have a power band in the upper range.
And yes I know Mazdatrix is very conservative, I just have issues with some of the things I've heard them say
Oh and of course a small bridge would make it all the better

OK, OK Ok this is pissing me off if your going to talk **** in my thread, DON'T
Oh and Martin just cause there stock parts there not junk i ran the same setup on my car and was making a lot of power.
Ok back to my stuff, i removed the stock tank and preparing to install the fuel cell, just got to cut the holes in the floor board to fit the lines and **** through, it actually will be easily fitted in. Pictures below
ANd about the porting job, the motor i plan on getting is a massively ported NA motor, maybe even with a half bridge too.

If you run a surge, I'd suggest using a walbro 255 or similar as your tanks pump, then fit the A1000 somewhere in the engine bay to suck straight from the surge (also bay mounted). Get some pics!

I still have to make something to hold the tank up there right now just the jacks holding it up.
My Clutch will be here next wed so the motor will be going in then.
Going to drop the whole rear subframe tomorow to replace some bushing that i ordered a long time ago but never installed.
More pics to come tomorow.

Aww, look at the flowers in that one pic.
Haha, looks cool. Can't wait til whenever I manage to see it. But I thought you said you put some new bushings in it a while back? Maybe you just said you ordered them... This was about 8 months ago??
