Cleaning Injectors?

[Bryson]

it ran awesome, pulled harder on the freeway, but it made a bigger difference once I put the injectors in. I had no choppy throttle problems or mid rpm band stuff, the car actually idled a bit smoother with the idle screw set all the way down, too. One of the two mods won't do as much as they will both do together.
Nando-I bought a rice-filter from pep boys and shot some k&n oil on it, mostly because i'm cheap :P but the filter is the perfect size

you saw Dave Adam's difference right? I mean if you remove restrictions of course it will help a lot. The AFM is the bottleneck right? ....choking the air supply.

The 12v head is the bottleneck my friend.

No.... your automatic is the bottleneck my friend

Damn me being away from the computer, and damn you Jordan, I was going to say the same thing! :P

I don't think 12V matters on a near-stock engine. Someone was babbling on Bf.c about how the exhaust was restrictive, not the AFM. :roll: Like Greg always says, the engine is just a big air pump. Remove restrictions and it will work better. 12 Valves aren't the weak link in the chain at this point.

I think it'd go like AFM, headers, intake box, exhaust, throttle body, intake manifold, or something like that. As far as things holding back HP, those are what I see as restrictions, and removing or lessening restrictions would "free up HP" The cam probably fits in there somewhere.......and down the road valve size and #, and etc. etc.

For example, look at Honda exhausts, they are restrictive as hell. Bolt up a free-flowing exhaust and might see 10+hp freed up. But of course there is a limit to where "bolt-ons" will free up HP, and seems the M20 doesn't have that much to extract really, or not worth the cost........(B25 with intake, maf, extrude hone, headers, exhaust would disappoint for the amount of $$$ probably) But, M30AFM here seems to have enough bang for buck to make it attractive.

It's all about VE - Volumetric Efficiency! 8) (haha, I'm such a future engineer nerd......)

I think I might try it out, since I have it lying around :P no need to hack up anything on my stock AFM, so if I don't like it I can always swap back. just need to pick up a filter and some material for a heat shield. I don't care if I don't gain 5hp, as long as it runs as smooth if not smoother and maybe improves throttle response. :)

is anyone using the stock intake boot? I know somebody was saying they got the stock intake boot to fit over the bigger AFM, I'd like to do that if possible since I need a new boot anyway.
