AMS Crank Pulley Dyno Results -16 JAN 12'
AMS stated that I would see up to 15HP/TQ gains, well I got RWHP gains of +13HP/19TQ. 
"...the AMS power pulley for the V6 application will produce up to 15HP/TQ at the crank depending on modifications and base engine power."
AMS Pulley Weight = 2.2 lbs
OE Pulley Weight = 6.8 lbs
Before
192.23 HP
202.52 lb ft torque
After
205.25 HP
222.05 lb ft torque
Gain
+13.02 HP
+19.53 lb ft torque
Progress to date:

Thats quite shocking dude, happy to see you're pleased 
I'm going to be following along in regards to your Okada project, it sounds like it is similar to the MSD ignitions thatI have run on all my cars in the past. I was unaware that there was a system for our cars, good luck and looking forward to the results.

Guess considering all my mods, balance is Key. I was shocked as well as the tuning shop who prior to me buying the crank pulley said there will be no gains just faster response. Now he's doing to do a blog about it...lol

Thanks boss, my jaw dropped when I saw the results. 
Especially considering that my car is N/A and considering that every single post about the gains of a lightweight pulley will be no gains to overall HP. But of course no one had a dyno to prove it. So hopefully this will put that argument to rest. Funny but even AMS gave an estimation of about gains of up to +15HP where they where actually correct.

I just saw the prices for the Okada units, $3K USD???
If it's like MSD it makes the car more efficient by burning more of the fuel with the hotter spark and longer spark duration, no question my track car ran a little smother and maybe picked up a mpg or so but there was minimal power gains (dyno tested of course). I'm very interested to see what gains or drivability differences you experience with them, you'd think/hope it should be a considerable difference for the money spent considering that it's more than 1/3 of the cost of a Kleemann supercharger system...
Good luck bro!

Got the Okada for 2K from VividRacing...Thanks Tery

Your crank pulley numbers are far and away the highest anyone has seen (other than AMS's own alternate reality dyno'd numbers of course) - almost unnatural... I didn't pick up much of anything with it on mine nor did anyone else that has dyno'd the car immediately before and after.
If you magically gains tons of power from the Okada then I am going to be flying my car to Japan from now on for all my mod work too!!! Maybe all the extra radiation in the air has something to do with it.

I believe you also said it's about balance. Others that you speak of that dyno'd after getting the Crank Pulley, did they have the same performance mods that I have?

13HP at the wheels from a pulley . . . . . . . . . . If I hadn't heard it from you I never would have believed it.
I've installed a lightweight flywheel in a car I personally owned. The difference in acceleration was VERY noticeable. The difference in weight on the flywheel I bought was over twice as much as the AMS pulley AND the lightweight flywheel I bought had its weight centered (picture a merry-go-round – as kids we all new it went faster if we moved to the center. Same principal). My difference on the dyno? zip.
BTW, nice photos from the auto salon. Very nice. You're two for two this week!
Wait, the 10th was less than a week ago. Make that three for three. Probably more. As the pulley has shown, I'm a little slow on the uptake.

Well it's still hard to say what the AMS would produce if it were only just the AMS Crank pulley installed. Would love to know how it plays it's part in HP performance in conjunction with the rest of the mods. Wish I knew a place that could do a dyno from the crank, that way I would know what HP my engine is now producing.
I forgot to check that

You must have remembered me once posting about my car being powered by radiation... lol

For instance, your ECU tune, headers, air intake, cat delete and high flow muffler all have to do with airflow and directly effect the AFR's. The car can more easily draw in the air, therefore draws in more air and the result is a leaner AFR - this creates more power by means of efficiency. The car is also exhaling the air easier adding to the efficiency.
The under drive pulley reduces accessory drag which is a reduction of parasitic loss. The sprintbooster is an accelerator pedal amplifier which does not result in any horsepower gains.
So, what about the AMS pulley? It's lighter, that's it. So all it is essentially doing is reducing the crank mass to allow for a quicker rev up, just like the lightweight flywheel mentioned by Marcus. There should be visible HP and TQ gains seen in the lower and mid range but it should make virtually no difference aside from a few HP to the total/overall WHP numbers.
Do get me wrong here, I'm not trying to dispute or discredit this thread whatsoever, absolutely not. I'm just continued to be amazed that physics in Japan can allow for such dramatic and unearthly gains!
In the end, I'm happy that you're happy dude, I'm really looking forward to the next mod of yours because that's one I'm interested in doing as well.

I'm not sure what mods all the others have had done but in reality based on physics on this planet it shouldn't really matter/make much difference at all.

Maybe the 9.0 Earthquake and resulting Radiation made some changes to physics.
Did you checkout the before and after dyno? I don't know how to translate dynos to where it makes sense to me but do you see any areas of concern?

Dude, when you're putting down over 200 ponies to the ground in a lightly modded NA 320 - I don't think you have any areas of concern.
If that result would have happened on the dyno in the speed shop I ran back in Canada I can guarantee you it would have been the same as what you heard in Japan, that being a pin drop...
When do the new coil packs get slapped in?

Plan is to throw them on with the NGK Wires and Plugs next week.
Still trying to find out if it would be a good mod to change out the throttle body and if so would it be best to change out the injectors. Only looking for bottom end to mid performance increases hence I'll never do the camshafts.
Winding down and running out of things to do to this car

And don't worry about running out of things to do - focus on other aspects of the car, you'll always find something

What you need to do first is calculate the increased airflow by the new larger TB and see if the OEM injector duty cycle can be adjusted to cope with it before you change out to larger ones. The larger TB and added fuel (Either by fuel mapping or injectors) is going to give you more top end than bottom, I did a TB swap on a car back home (65mm to 72mm) to get a much better top end for use on the track (adjusted cam timing as well), it was quite a difference I lost some bottom end.

Thanks for putting things in perspective, I didn't think 205 rwhp was respectable.

Well guess the TB is out. Everything is done besides a custom stereo system which isn't a hi-pri for me. There is only one more mod which I'll have to find a place to do and that is have the lower control arm shortened so I can get this camber set straight. Tired of running through front tires every 6 months.

Glad to hear of your positive results. Obviously AMS has been acquired by a new tuning firm and no longer exists. They are now have all the existing inventory. and are selling the remaining units at very good prices from what I have heard. Contact them for more details of course, they would love to hear of this good news as well, be sure to email them (link is on the website link in signature below).
I told you the gains were there. Usually the more mods you have the better it will respond ... stop listening to all the negative nonsense haters (99% of them had never even touched our products) ... it really does work and now you know it. I must say it certainly feels good proving even the skeptics wrong from time to time (even if it is too late anyways) lol. Vindication is sweet.
All the best,
AMS

Nice gain !! I work on aircraft engines CF6 series, our customer always want the lightest thing in their rotoating parts. Less stress on everything like bearing .... On and on Everything helps and it's not about the size of the parts also. Kleemann supercharger is not the most efficient blower on the market also. Consider the price and the size.
It's like if you are wearing a softer and lighter shose, I don't see why not you can't run faster. Putting efficient power down.

Repairs before mods is always a good idea Do you have the coil packs now though? Just wondering about the look and dimensions of them.
