What happened to my other ghost post?

Oil filter test in the bigger throttle body?

I think there are better things to be messing with imho. Why people spend hundreds of dollars on throttle bodies as one of the first mods doesn't make any sense to me...

It's not a first mod. It's his last mod, as in last ditch effort for max power on pump gas on the stock turbo, without getting to crazy with high comp pistons, ported head, or other fuels. Max peak power is not everyone's main goal. Nice wide powerband with lots of power beneath the curve is what Kracka's goal is here.

The comments about oil filter tests are a little aggravating to be honest. We go through the effort of doing something to better the info available to the community and comments like that kinda wear me down after a while. Taking a shit on our blood/sweat/tears does nothing but make me not want to do something like that again, despite all of the thank you's we received.

Shane, that's the plan :)

If you really want to test the part properly, don't do it at max boost and the limits of the turbo and the limits of your octane. Turn the boost down to 19 or whatever and run a tune that isn't close to the edge and doesn't knock at all. You might also want to flatten out all your timing tables so that it will run the same ignition timing every run. It will be hard to see the true gains of a specific part, if the turbo is maxed or your octane is maxed.

As far as Skunk2, welcome to the world of Honda throttle bodies. Leaks, not matching to the intake manifold, sticky throttles, idle problems, etc. I wouldn't be surprised if the 68mm TB didn't lose power in the midrange or not gain much up top. The 1G DSM TB has made 850awhp, Hondas make 500-600+ on their stock TBs. I am not saying that a bigger TB wouldn't help on a car like that, but it isn't a part that is known to be a big gainer on most cars.

I have been disappointed by the bored out TBs, ported intake manifolds, ported/coated exhaust parts on the Evos and Subarus. You are lucky to get 1/10th of the power gains that some of the people hawking these parts claim.

One other potential reason you might not see as big of gains is that you guys are trying to do an objective unbiased test. While some others will make sure to take the worst possible "before" run versus the best possible "after" run.

Hopefully the Skunk2 TB is a good piece. I hate TBs that are too touchy or sticky.
Thanks for the insight, Shane! I do agree with what you said about not running the turbo on the edge. I did turn down the boost to 22 and during each of the pulls I was showing zero counts of knock with a quick 1-count here and there randomly. I also did pull timing back 2* across the majority of the powerband. I am trying to be as objective as possible here; peak torque was consistently up a bit with the ported IM, but it was very small and was within what I considered to be acceptable error. As for the whp with stock we did 3 pulls: 374, 376, 378; with the ported we saw: 375, 376, 380. Again, slightly better results but nothing notable and certainly not high enough to be considered true gains. Now, once the lowest #'s with the new parts are higher than the highest baseline #'s we'll be on to something.

I do also hope this Skunk2 TB is a good piece; it certainly looks nice in all its sexy billet goodness, but if it continues to suck on the car I will not hesitate to send it back to Skunk2 and either stick with stock or find another aftermarket alternative.

This is hardly one of my first mods. The reason I'm doing this is to try and take my stock turbo/pump gas setup a step further. My goal is 400whp DynoJet/350whp DynoDynamics which is a lofty goal but I'm hoping to accomplish it. I have no interest in getting a larger turbo anytime soon as I feel the stock turbo is a great mix between good top-end power and quick response down low and during shifts. I also am not willing to run E85 or any other alternative fuel for numerous reasons. I'm asking my car to do a lot of things really well and so far it hasn't let me down so if I don't reach my power goals it won't be the end of the world. Its been great as a daily-driver and performed very well for me in autocross; both of those are my reasons for requiring a large powerband with lots of area under the curve.

We did a little more testing tonight and with some additional porting to the intake manifold runners its sitting at the same peak whp (378-380) but making an additional ~25whp at 7250 rpms.

16G powa!!

I can honestly say that right now I wish i would of kept mine or went with a new E316G again, power was awesome and would of only gotten better with cams and IM and this sweet transmission i have.

We're up to 381whp and picked up 8 ft/lbs of torque today while still on the stock throttle body by getting a bit more wild with the "stock" intake manifold.

We got the Mil.Spec 65mm ported stock throttle body installed today and picked up another 2whp and roughly 10-15 ft lbs of torque depending on the pull putting me at a final 383 whp and 380 wtq on pump gas with the stock turbo. This concludes the intake manifold and throttle body testing.

We were unable to get the Skunk2 68mm billet throttle body to work since it refused to hold air, but this Mil.Spec unit is really a great piece. It feels/drives/idles just like stock so the quality of machining and assembly is definitely on par with the OEM factory. Plus it has high pressure shaft seals which are rated to 25+ psi whereas the stockers are only good until about 7 psi.

I'm sure MAP will post more info about their v1, v2, and v3 intake manifolds within a few days, but I will say my v3 is quite sexy with a semi-gloss black heat dispersant coating. The coating combined with the heat-barrier gasket and TB coolant bypass has left the manifold cool to the touch ever after multiple pulls (stock it would get hot enough to burn your hand). Flowbench testing also confirmed it flows more and the runners are more balanced compared to the stock Evo intake manifold. I'm sure I'll have pictures up tomorrow or Friday.

Sounds good! sounds like it looks pretty nice to, excited for pics!
