Skunk2 intake manifold
#361
You can definitely re-use the Honda s2000 TPS though.. at least if you tell Ktuned that you need the TB setup for a B-series TPS.

This is VERY interesting. Can you elaborate further, maybe post a pic of the manifold in the car? Did you order the different runner lengths and sizes or weld and finish them from parts? Are you using the velocity stacks?
#363
I am interested to know about the excessive manifold as well. How much more power and where are you going smaller with the xcessive? Also, do you have any previous version looking to part with? I am still not believing the power the ultra race gave me was correct cause my engines my issues. I think there's more potential but nothing drastic. But, at the same token, I am ready to slap something else on there and be done with the project (with some given thought).

Not sure if it's been tried or not but has someone tried the skunk2 ultra street for a K. Things I know of are much longer runner length, backwards tb location, smaller plenum and how if installed on to f series it will be curving down towards engine mount a bit. I don't know if it will fit with an adapter since it curves downward. Seems like my engine is needing this.

You get your unknown vacuum leak sorted out? Before you invest too much time/money in alternative IM you should really make sure you've got the ultra race properly installed/tuned/etc.

AFAIK, street won't fit with adapter (see: here). You'll hit the brake master cylinder et al.

Here it is.....my review on the skunk2 intake manifold.
I dyno'd my full bolt on S2000 today. The results were surprising to say the least. I finally got all of my S2Ks issues sorted out and put the manifold to the test. The test was on 93 octane gasoline. Engine ignition timing was recalibrated and everything was looking normal. Air temp was 65 degrees F and plenty of sea level pressure in the atmosphere. The engine had to be fully re mapped, so, to me things were looking good. Then came the power runs....After we blew the coolant vent line cap off and sprayed the wall It started to turn for the worse. Just going to jump right into it......the car made just shy under 210 whp......thats right....UNDER 210WHP!!!! We hit the timing threshold on the ecu (don't know that figure). Fuel was good, air was more that sufficient in the manifold. At WOT the value never strayed from -0.3 in/HG. The OEM manifold put down 263WHP on this same dyno with other mods that should've flowed less air. Tuner double checked dyno calibration and whatever he said made sense at the time. I couldn't repeat it. He did lay the graphs over each other on both pulls and they were nearly identical. The saying remains true...bigger is not always better....(insert sad song). I took the car for a test drive and it really feels down on power.....the car sounds freaking amazing....but its all show and no go...I will say that it does feel maybe a bit stronger down low. After 1-2K after vtec it feels as if I am lifting the throttle and it just feels like it would be the intake air has gone stale.
Conclusion- Going to check compression and engine timing. If those check out...the manifold will be taken off and modified OEM will be used. Runner design (esp. diameter) seems to be the culprit. Twice as large than OEM plenum doesn't do a whole lot of justice either.

Well thats interesting and disappointing! its too bad about the coolant leak issue possibly tainting things for a clean run without doubts. Shouldn't have really caused any issue, but who knows. Probably good to do the comp/leak down as you mentioned just to pinpoint it is the manifold or not.
You also change your exhaust system too right with the gern pipe? Couple new variables there from your 263whp set up which is great power NA out of an F22. Might have to sell some parts and get back to that and just call it winning.

@khahoang91 yeah I’d hold off until I figure out if my engine is mechanically sound. I do not think the piping design had any influence on the output. if it means anything to you, the air pressure in the manifold was all there at WOT (according to the logs). Would I be incorrect in thinking that there could not be anymore flow if the pressure is atmospheric in the plenum? I’d be all for trying another intake if I had one to test. I am not sure if I have enough 3.5” tubing. I def. don’t have a 3.5 bellmouth.
@s2000junky we did try the gernby first. If all went well the HKS was next in line. It just wasn’t looking like a 50hp gain could be had with the Parts on stand by. Dusappointibg yes...esp. during my test drive. Felt so bad. The s2000 had so much more in it. Those parts will be sold in a heartbeat if I can pin point them to be the problems. I just hope my injectors will work with my s2k Parts. Got any turbo buddies looking for some up? Lol
