Cool thanks, my manual did not even have that listed in the Fluid capacity section :O

 

iirc the gear oil is sold by the liter

 

No prob. Sometimes I wish I was living in SoCal still so I could be at all the events and get all the stuff that is in the marketplace without having to pay for shipping!! LOL

You're not sold on the vortex ring - you talking about the TB spacer? What does it take you to be sold on it? I have one. Guess the bandwagon approach isn't good enough? How about I make power all the way to redline.

Oh, and the 75w-140 would be ok but once it starts to heat up you'd probably feel sorta sluggish because of how thick it would get compared to the 90 weight.

 

I second that! Oh wait. . .I have a kid now. My car budget shrank drastically. LOL

Yeah, bandwagon approach doesn't work. And the whole thing still doesn't make engineering sense to me (and like Mr. Motordyne, I'm also a "rocket scientist" albeit a "dumb" one.) But if it works for you. . .excellent. Some people swear adding an ignition booster and turbonator will add power too. Meh. ..on second thot a TB spacer is probably the only mod I could easily afford right now. *Sadness*

Which is what I read on bimmerforums. . .one guy said exactly that after trying it.

Oh. . .and best thing ever. . .I called the place I bought it at and asked if I could exchange them for -90. They were cool with it even though it was over a year ago that I bought it and I didn't have a receipt. So. . .no more 75w-140 for me, EVAR! LOL

 

I have a 1 year old daughter now...changes everything. Not only is my wife not working now all the money seems to go towards her. My car budget gets neglected. haha

The throttle body spacer makes sense to me. In that 60* angle bend you know that air will slow down around the longer edge. The spacer redirects the air so that slow spots aren't developed.

 

Amsoil is sold by the quart (946ml or 0.946 litres). In any case, you need two.

 

Don't you think an improvement like that would have shown up on Hydrazine's dyno test?

 

this is exactly what I would have done and the outcome hoped for.

Cool, it all worked out

 

no point in trying to convince of the TBS - as you probably know, I've gone in circles about it... buy I'm glad you concur (you are one of the more logical out here).

BTW, I don't know how you guys are able to pay for kid(s) and still have a G and mod it... I drove a beater for 12 years while paying for my kid... but I was much younger and didn't make as much money.

 

maybe I'm thinking of Mobile 1 (I think this is liter bottle) http://www.mobiloil.com/USA-English/..._75W-90LS.aspx... I remember trying to figure out how many bottles to get when I changed the first time... I went with Ams when the gears and diff were installed.

yes, Ams is quart - good looking out

Redline is sold by the quart too.

 

Kids, FTW! Mine little dude just said "dada!" for the first time on Sunday.

I'm glad it works for you, but. . .I just don't agree that the "slow spots" will change. In order to affect the velocity through the bend, you have to physically reduce the angle of the bend itself, or change diameter of the piping, not just lengthen the intake pipe. And all the discussion I've read of "rifling" doesn't have any effect until the pipe length is a meter or so long. If the entire intake tube was rifled, that *might* increase swirling, but even that doesn't change the fact that the swirling air will still have to make a 60* bend. I'll go blow the dust off my Corky Bell "Supercharged" and see what it says in the intercooler piping section, since I think it discusses flow around bends.

In other vehicles, they come to the same conclusion though. Here's some research from jeepmagazine:

Jeep 4.0L Myth Busting - True Lies
4.0L Myth Busting
By Christian Hazel, Pete Trasborg

Over the years, Jeep's 4.0L engine underwent a few changes here and there, but nothing drastic. Despite the similarities, many still think of the '91-'95 XJs as the fastest six-cylinder-powered Jeeps in stock trim. For some reason, the '97-'01 XJs just don't feel as fast. Did they change the engine? Did OBD2 kill the 4.0L? Probably not, because if you drive a '91-'95 YJ or a '97-'06 TJ, there's no appreciable difference. The older XJs probably just feel faster because they have less sound deadening material and some other heavy components. At least we think that's the case. And with that, let the myth-spinning begin.

We've heard dozens of fish stories about how to make power with the venerable 4.0L Jeep engine, which parts are better, and which ones are wastes. Well, we've got around a half-million miles under our tires thanks to the trusty 4.0L Jeep inline-six. We've also got well over 100 dyno runs on these engines and have a good idea of what makes power, what improves drivability, and what wastes your money.

Jeep 4 Liter Engine Myth Busting Throttle Body Spacer
Throttle Body Spacer
Myth: Adding a throttle body spacer will increase the intake plenum volume for more air and a higher velocity intake charge. Also, rifling an aluminum spacer helps air flow into cylinder head with less turbulence for more power.
Our Thoughts: Depending on the application, a spacer works wonders on a carbureted or a TBI-injected engine in which the air/fuel mixture atomizes and flows through a wet manifold, but results are less drastic on a MPI engine in which only air flows through the intake.
Claimed Gains: 10-15hp
Actual Gains: 0-3hp
Notes: With our Red and Mileage Master projects, the largest power increase we've seen on the dyno was 1hp.

Even the Toyota Tundra guys drastically shun them:

And, as I said. . .if Tony--the Flow Bench Master Guru--says they're not of any benefit, I give him the most weight in the VQ community. Bad enough for Tony, bad enough for me.

But, again, if you feel it works for you, and it makes you more power on the dyno, good.

Okay, so back on topic. My oil is all changed. I have 2 and a half more quarts of 75w-90 now. I'm happy.

 

haha, ya I've heard that Tony doesn't think it will make power. Did he ever do any flow bench testing with one?

 

Tony was there observing the dyno test on Mike's car. Tony's conclusions aren't based on what he thinks. It's based on the dyno proof presented.

 

A lot of the modding to my car was before the baby showed up. Now I have to do things myself that don't cost a ton or where I can recoup some back by selling the OEM. Fortunately there isn't much left that I can do and I do ALL of the work on my car myself. Saves a lot of $$.

My little girl is almost 15 months. This morning she was saying "Dada where are you?" when she woke up. So much fun to watch them grow up.

But he never tested it on his car? Didnt you show gains with this on the dyno Mike?
