Intake manifold for blown Zetec?

so the Focus sat for 5 years, and i noticed a good size crack in the 2000 stock plastic ported intake manifold. I have the fs/vf Vortec blower kit with a built motor & ported head. Is there any new manifolds on the market in the last 5 years :lol: or just find another 2000 intake & port it?

this. Chaz's is a copy of theirs since TOP speed decided to leave everyone hanging from a cliff as far as communication.

doesnt mean that putting one wont show gains even over the outdated FIRM design. the runners are too long.

and FYI the TS/NERP is a take off from the honda world applied to the focus. aka: universal therory

If the TS/NERP were with the flanges and not have to look for the SVT lower. That is the only reason I have not got one of them.

Everyone that I find doesn't want to split up the lower from the upper.

ask Ja-rad he had a ported 2000 and then used the TS one.

i know TS had a stock zetec auto with a gt2871r on it and it made like 260whp compared to 212whp JUST switching intake manifolds from the stock plastic one.


its worth the gains and the way it makes the car keep pulling harder to limiter. my car never fails to keep pushing u in ur seat harder and harder. its a crazy sensation compared to a car that dosent have a curve shape like that.

I guess its a tunning thing the stock TB actually ran better than the 65mm tb I had on orginally but the TB is also ported. Basically I need a new manifold either way so if its worth spending money for the TS manifold to gain HP then I will buy it.

Mine and jims in NOT a copy of the ts mani. Just because ours never went "into full production" like theres (and we all see how that turned out) doesnt mean ours is a copy. Ours has machined stacks on the base plate. From what i seen of a ts mani there were NO stacks of any kind.

I also put our design into computer flow testing software and made tweaks to the mani until i saw the best results.

it doesnt have stacks because its for forced induction, air flows like water, it has a router'd fillet instead of a velocity stack on each runner.

Just because it is forced does NOT mean it shouldnt have stacks of some kind. You might as well say a ported head or runners doesnt help either. The smoother and easier air can flow the better it is going to be.

show me ONE good mani that a lot of people are running and making power with on Any car platform that doesnt have sone sort of stacks or radius.

As ive said before i HAVE put multiple setups in a simulator WITH forced air simulated and non forced air. And the difference with stacks vs nothing is Rediculous.

Jims was already proven to make 600+ and we started working together on them to give the best of both worlds, machine and welding wise.

mine does, it doesnt have stacks it has a radius, ur arguing with me :lol:

Seems to me there's nothing magical about the TB being mounted at one end of the manifold. Couldn't a TS/Nerp style manifold be made with the entrance on top, to accommodate the centrifugal supercharger IC piping on this car?

A manifold could be made to keep the throttle body at the top but it simply doesnt spread the airflow to each port like you want.
Without a huge design change of the plenum.
If it has a "standard" plenum with tb up top the air hits the bottom wall and almost tumbles and doesnt flow to the ports like you want, where as the side mount tb has the length of the plenum to divide the air up and spread with not as many drastic changes to the airflow.

that all makes sense just wish there were a way too make it work with my set up. The bends I would need to make I feel will restrict all that I would gain with side mount intake. They have made just over 3000whp with stock intake so I don't plan on passing that mark, but hope too reach it.

cant you reclock the blower and put a FMIC and make it work?
