I was wondering if anybody has used the F-150 kit on their Sho, Flex, MKS, or MKT. I looked up the pn on the F-150 and Flex throttle bodies and both have a pn of 9E926. If this fits it's seems to me that it would be the best option for the w/m installation. Would this be correct or would there be a better option.
I installed the Snow stage 3 but part number 20100
I was more interested in the throttle body spacer since it gives a mounting point for the nozzles.
Meth injection is definitely on my list. As far as injection points, I will be having a hard pipe built by EPP with a bung on it to replace my IC to TB pipe... Mostly aesthetics though so I can get it black ceramic coated to match the rest of my underhood piping in the charge system.... and it will be more costly than a TB spacer.

Ahhhhh, ok. I had looked into this before but decided not to use it. Since it is behind the throttle blade you have to use a check valve so it's not just constantly being sucked in due to vacuume. Who knows. Maybe it works better. But I'm good with my nozzles. And I too would consider buying the hard pipe with a bung on it eventually. Would be way nicer but stock is workin just fine for now.
The only difference between the stage 3 ecoboost kit and f150 kit is the injection plate its 50 bucks. No need for custom fabrication. Could have the plate powder coated black to match the black in the engine bay. More curious about bolt pattern which if the throttle bodies part numbers are the same one would think the bolt pattern is the same. Only other part would be the added thickness if it would cause any fitment issues to the existing piping.
I emailed Snow a couple of weeks ago and the reply was that the plate won't fit on the SHO.
Too bad! This would have been a good option. They can't make one for the SHO? Do they need anything beyond measurements of the mounting surface?

How about taking an Airaid Poweraid and making it thicker so a hole or two can be drilled for meth/gauge?

Good thoughts Manu...
On the AirAid, why do you think the interior is ribbed instead of smooth like all the other TB spacers I've seen? It would seem counter-productive from a flow standpoint.
Probably to induce swirl and provide better "atomization" of the air. I don't know if it is as effective on these modern engines, but high swirl combustion was an engineering feature of Ford's back in the 1980's.

Also, swirl appears to be used in cases where you want to increase cylinder filling (more power/performance), and doing so through the TB spacer is relatively cheap compared to porting the heads:

The effects of swirl and tumble on combustion in spark-ignition engines
Abstract
A review has been made of rotating flow (swirl and tumble) in premixed spark-ignition engines and its effects on turbulence generation and flame propagation. Rotating flow can significantly increase turbulence intensity during the combustion period. This in turn can lead to a reduced burning period and increased thermal efficiency. Rotating flow, possibly in combination with squish, can be particularly important for combustion of lean mixtures or with alternative fuels of low laminar flame speed. In general, rotating flow can substantially increase flame propagation speed, reduce cyclic variations, and expand the lean limit, though excessive rotational motion can have deleterious effects on induction system flow resistance and also on heat transfer and thermal efficiency. Much research work has been devoted to swirl (rotational motion around an axis parallel to the axis of the cylinder), but in recent years increasing attention has been paid to tumble (rotational motion around an axis perpendicular to the cylinder axis). Swirl and tumble have distinctive characteristics and can interact differently with piston motion and squish. The optimum rotating flow field may be a combination of the two kinds of rotational motion. The principal features of the mean velocity and turbulence fields associated with these rotational motions are reviewed, as well as the mechanisms for decay, generation, transport and enhancement of in-cylinder turbulence. Substantial advances in experimental method and in numerical simulation are leading to better understanding of the effects of swirl and tubble on engine performance.
Swirl also helps increase low-end torque apparently.

The bottom line here is that a parallel valve two-valve bath-tub or wedge chamber design has inherent swirl properties. This means a head designer would have to work hard to eliminate the heads natural advantageous tendency to swirl the mixture (and believe me some have managed to do that). For a two valve head then the natural tendency is to swirl the mixture and this, in part, contributes to a two valve heads normally superior low speed torque.
On the other hand a conventional four valve head has no natural tendency to swirl - but it does have a tendency to 'tumble' the charge. The following illustration shows the difference between the two.

I just ordered the Snow Performance stage 3 direct injection system part #320. Hopefully I'll receive the system by next Tuesday. I'm having a friend of mine make me a throttle body spacer since there's no companies out there making them for us. My only reason for having it made is to use it for my nozzle setup. I'll keep everyone in the loop on how it turns out.
You should have it by Thursday :)
Actually just looked it up... I'll be here tomorrow... That's crazy!!! I just ordered it yesterday! Thanks Mike for everything
