Great dyno numbers. Great thread, we need more threads like this. The 4th GEN forums are so boring, nothing is performance orientated.
I noticed the 3rd GENS camshafts don't do well after 6000 RPM. On my dyno chart, I made power to 6000 RPM and than it stayed steady (FLAT) all the way to 6800 RPM. I should scan my dyno chart and show you guys what I mean.
that is because 4th gen owners are more concerned with what tint to get and what 20" rims will look best on their car. I guess that is about the same for the new 3rd gen owners that seem to be coming on here lately too. oh well....but yea, I would like to see a dyno graph of a 4th gen

In for dyno. I don't think it's the camshafts that are the problem but the restrictions in flow. The car was made for performance with economy on the mind. With some modifications I could easily see a 3rd gen making power all the way to 6k and plateauing. Now add on an extended redline and SSIM and it'll make power all the way to the stock redline.
You know, maybe its just me, but the SSIM, well I know it makes topend power til redline, but it seems that it would really, and I mean really perform with FI. You know what i mean? Seems made for a monster gain, and would def allow for more low end tq on a turbo given the compressor wheel is very well selected/matched to the enige. Ideas?

Go for it, and an oh by the way. I will be working on my 3 inch Intake and smoothing my SSIM some tonight. Hey Leathe you got any pics of what the inside of your SSIM looks like??? Looking at one from the guy on maximas.org(iirc it was 02altimas SSIM from KRRZ350) I dont think that mine is that rough after all.

Nope, don't have any pics, sorry. I purchased mine off at a Maxima (05+) that had the full service done on it. Shelf cut out, polished and port-matched runners. The only restriction is the lower intake manifold which is untouched. But most of that stuff will be going up for sale in a little bit if a deal I have doesn't fall through on another project.

Please keep us posted on the 3" intake, and you are using the land rover maf iirc right?? please post pics and any other info you have or will obtain on the intake. And i have a UR pulley on the way, how hard is the install on a 1-10 scale??(sorry for the way off topic)

On a 5spd with air tools and a lift it should be no problem, all you will need is someone to hold the brakes for you and the right belts to replace the old ones.
Without air tools or a lift and my friend helping is how I did it. All I can say is please take your friend and find some airtools and a lift, its only a 3 as far as technical difficulty goes but it scores a 9 in annoyance for trying to get the crank nut loose with a breaker bar laying on your back under the car on jack stands. The more room the better but as long as you have air tools it will be absolutely no problem at all.

i guess the 4th gen owners are like the 2.5s owners here.
lets see that dyno.

NOTE: You can see that my torque figures are off. I asked the owner why they were so low, he told me that his dyno reads 8-10% lower than a dynojet. He has showed me some examples and I told him fair enough. His car on a dynojet made 328 WTQ and then he dynoed it on his and got 296.86 WTQ.
Even at a 8% loss, I am making 235 WTQ.
This run was with just a Fujita SHORT RAM intake. I had about 6000 miles on the motor at this time (Not even really broken in yet at that time). I have about 16250 miles now which still isn't the sweet spot for the VQ.
As you can see, there is NO drop off in power from 6000 RPM and on. This is due to the CAMSHAFTS and if I had a 7200 RPM rev-limiter, I believe it would still would have made power because at 6800 RPM it was slightly climbing.

hey man just one question. bout 3rd/4th gen diff. i know my 2005 is about 250hp stock and isnt all 4th gen 270hp stock? i know 2009 is 270hp

Yeah,
Your right, the 07-09 had 270 BHP and the 05 had 250 BHP. You think my 242 WHP is actually crank BHP? There is about 17% drivetrain loss when I compare my stock run 231 WHP. So I am actually making 283 BHP if you want to go crank power. The 3rd GENS dyno around 210-215 WHP where the SER dynos around 220 WHP.
ohh yeah. i hear its only the 250 for 05 at the flywheel? i knew it lost some by time it hits the wheels.
im curious even with a cvt what engine components can i switch without messing with the cvt? like flywheel and stuff. i know i can do the crank pulley but not much else i know.

You have to do engine bolt ons. CVT's don't have flywheels, they have flexplates which is like 5-6 pounds where the flywheel is around 20 pounds.
