I remember reading a while back.. somebody made an aluminum pulley that was stock diameter... just can't remember.. Been suffering from CRS (can't remember shyte)

OK - you win - you can really dig deep for parts. (except Stillen does not have a pulley for 95-99 Maximas). The others will require attention, if I can find real data on the pulley construction, so that there is enough meat on the front of the pulley to securely mount a trigger wheel. Unorthodox used to have a standard sized pulley, but not today, from what I saw on-line.

Thanks...

Are you looking for the entire harness or just the two cam sensor plugs?

grey99max

iTrader: (12)

I just need the two cam sensor connectors with wire pigtails - with the small harness would be OK too. At least I think that's how it comes from the factory, as a short cable with the two cam sensor connectors and one other connector for the main harness.

The two are different, looking at the cam sensors themselves. Got connectors?

John says he's done, wanted to know if I wanted a converter built as well, told him I already have one so please ship the transmission back. Yea !

Sweet news on the transmission!

I would run the stock balancer and try to work out a way to mount the wheel to it.
Seems like the aftermarket balancers aren't the greatest quality and that's an important piece to keep a motor happy.

ABIGBRAIN

iTrader: (1)

SWEET!! Are you planning on trying it out before the snow starts flying?


It is my understanding that VQ's are all internally balanced.... what we have on the crank snout is just a belt pulley with timing tabs. I believe calling it a "balancer" is in error. I think the crank pulleys I linked Harold to are all quality pieces.

Apparently some of the aftermarket ones as - questionable - at least the OBX is known. The OEM pulley, with the rubber insert, actually serves to equalize the weird forces on the crankshaft when the engine is running, I've read articles about how the lack of a "damper" front pulley can help destroy an engine at higher RPMs. Dunno the truth of that, but staying with the OEM would be my first choice.

Looking at an OEM pulley, there is a nice flat ring on the inside, toward the front, that measures 114 mm diameter. (that's about 4 1/2") If I had a piece of steel tubing with 114 mm O,D. , that would fit inside that ring, perhaps as a press fit. If that tube was cut off to match the front of the pulley, then a steel disc could be welded on the tube to provide a flat mounting surface for a trigger wheel.

Or - going one step further, first machining out most of the inside of a trigger wheel to be just smaller than the 114 mm tube, then centering the trigger wheel to the tube and welding the two together would make something that would press into the pulley and support the trigger wheel. One the wheel is indexed to the right position, I think a MIG welder could reach inside the trigger wheel so you could spot-weld the 114 mm tube to the pulley. Not a long nasty weld, but just 3 or 4 quick spot welds so no rubber is cooked.

That sounds like it might even work. Hmmm... gotta think about this one.

If I get everything installed and all works, darn betcha it will be on the road. We have some tracks within 200 miles that are open thru the end of November, and there is always Houston... That's why I have a trailer and tow truck. Better late than never.

I'll need to tow the car to a Haltech dealer for "factory" installation anyway, so to have a warranty. Wichita KS, Tulsa and OKC in OK or Omaha NE are the closest dealers. Dallas has a few and they have Yellowbelly outlaw 1/8 mile drag strip (open all year) for "testing" how the Haltech works.


EDIT: I just ordered 2 ft of 4.5" OD steel tubing. Gotta have "parts in hand"...

EDIT #2: A more common term for the crank pulley is "harmonic balancer" - more than just a static balance is required here. The reason for the rubber...

can't wait to see this thing hit the track again

Me too - but I might have to do more driving to get it on a track late this year.

Maybe that would be good practice for towing to the Texas Mile or one of the Houston Miles...

Have you received your transmission back yet?

grey99max

iTrader: (12)

Nope.. John hasn't answered my "When ? " question. On the bright side, I think I've figured out a pretty simple way to mount a 36-1 trigger wheel on the crank pulley. Details to follow once I'm sure...

You're going to make me buy one of those GoPro3 cameras, aren't you? It's probably time to do something about in-cabin recordings...

I asked John at IPT how the build went:

"Hi, Everything looked really good and I was happy with how it came out."

so there's hope.....

..and yes, gopro3 is in your future grey.

grey99max

iTrader: (12)

Gaaa... I really don't need one more thing to do at the starting line. Now, I think the gopro3 or 3+ has a wireless remote so that maybe I could start and stop it from a wireless remote. If I even remembered to do it. Between the hurry-up-and-wait dance in staging, shutdowns for others blowing up during their run, and the do-just-one-thing focus you gotta have when staging yourself, (clear the transmission computer, check wideband, RPMs, nitrous systems enabled, fuel pressure up, three temps down) somehow taking videos of the back of my helmet just gets overlooked the few times I've tried it.

Yeah, I know, this is a no-whine-zone, so if I can find a video recorder than I can use, then maybe I will...

And No, the transmission isn't here yet.

t6378tp

iTrader: (69)

Yeah I'll post some links in my build thread

Btw the gopro hero 3 black edition has a wireless remote that u can have someone in the stands turn on and off. Or turn in on when they flag u to stage and trim the file later

Smarty - don't you wish??? It showed up Friday afternoon, at my shop. But, they won't be able to get to it until the week after Thanksgiving week. Oh well, at least this will happen.

grey99max

iTrader: (12)

I've only read about this wireless remote thingie, but if I have the camera mounted and turned on, then I could use the remote to start and stop recording? I almost always travel by myself, so can't rely on help from others, so if I do this thing, I'll need to control it.

Where would be the best place to mount it for the Texas Mile?

ABIGBRAIN

iTrader: (1)

Suction cupped to the cabin side of the sunroof glass.

grey99max

iTrader: (12)

OK - that could work... unless that's too high to see what's going on past the hood. That seems a little high. Anyway, if I can control the camera with the remote, that would make it easier to manage... regardless of where it's mounted. Maybe on the passenger seat head rest?

This won't happen for a few weeks anyway. Most all track schedules are done by the end of November...

Was doing some research on the RE4F04's today and came across some interesting info. Based on what I found, it seems that there are different diameter torque converters based upon what engine was being used. I admit I was kinda surprised (while at the same time i wasn't) that Nissan did this.

VQ30DE powered RE4F04's
Dia. 10.75" Pilot .785" Hub 1.730" slot, mount 4 pads, 20 spline, Code GB, GD, GE.

QR25 Altima powered RE4F04's
Dia. 10.0" Pilot .785" Hub 1.730" slot, mount 4 pads, 20 spline, Code HC, HE, HI.

I would be willing to bet that the Altima QR25 converter would probably stall a bit higher than a stock VQ converter when bolted up to a VQ motor.


Is this something that you can verify? Just the diameter of the converter casing itself, since you have both transmissions.

ABIGBRAIN

iTrader: (1)

Here is where i had mine.






With a longer support rod pointing down from the suction cup you would be able to angle it in a way so that the rear view mirror is not in the way. You could even suction cup it on the inside of the rear window (as Aaron has done)

grey99max

iTrader: (12)

I do have both converters sitting side by side on the garage floor. The outsides are different, but I didn't measure anything since I have a much-modified torque converter installed now. When do you find this stuff? not complaining, just wondering. I'll photograph and measure both of them, since you're curious.

Now I hope that the converters are interchangeable, since I'm hanging a Maxima converter on the Altima transmission...

grey99max

iTrader: (12)

Now I remember why I once tried a helmet camera for videos, so as to get as much of the driver's view as possible. Not an immediate problem, anyway, but thanks for the ideas.

EDIT: I tried a cheapo Tony Hawke helmet camera from a biker buddy. It really wasn't up to the job, but I bet things have improved over the years.

grey99max

iTrader: (12)

Just took pix - quickly - it's 27* F in the garage tonight.

By my eyeball, the converters are the same diameter. I'd have to set up a measuring device to be sure. The major difference is that the 2001 Maxima converter has another row of bumps compared to the 2006 Altima converter. Maybe the Maxima converter is built to handle more torque ??

Thanks Harold for taking the time to go out and snap the photos in the cold. I can see from the photos that your Maxima converter does have the correct "GD" code on it. The Altima one is more difficult to see it's stamping. I can also tell from the photos that the Altime converter is indeed smaller in diameter (on the cover side and not the backside) than the Maxima one. As far as the VQ converter being "stronger" than the QR... I'm not thinking that's the case here. It is more likely a smaller size in order to get the stall up towards 2500RPM or so given that it is used on a lower powered 4 banger. In drag racing circles (as I am sure you are aware of) smaller sized converters will stall higher that larger diameter units with all other factors being equal.

Thanks again for doing the "dirty work" for me. I do appreciate it.

iTrader: (12)

I didn't think to look for the codes on the TCs - I'll do that later. I'll also attempt to measure the cover diameter of both while I'm looking at them. So you're thinking that the Altima TC would stall higher when behind a VQ? Interesting... but only one good way to find out. Do it....

We are having a "gathering of the clan" for Thanksgiving this year, and there will be one or two late-model 2.5 L Altimas here. I can test your stall theory very easily. If they have tachometers... hmmm.. We shall see. Happy T-day.

I tried last night with my daughters 2003 2.5 S model. I powerbraked it up to 2400 rpm before the tires started spinning. Might go higher since the pads, rotors were wet and there was a 1 inch layer of hard packed snow on the driveway.

Anyhoot, Have a great Thanksgiving and enjoy the turkey coma.

T-day is done, and people are going home, so I got one daughter to test her 2007 Altima 2.5 - it would stall up to around 2300 on dry pavement. If I was doing it, probably 2400, but the car is named "Allie" and it's her baby, so she did the test.
