Cam gears for V6. Add power AND mpg

I like your thinking.

 

Let us know if you do, I also have the intake manifold spacer in as well but haven't done my cams yet so would love to know if I should take it out when I do the cams

 

Will do. Its more for curiosity tbh. Ill do some before and after data logs. I lean to the side of MPGS > performance, so ill gladly sacrifice some performance for an mpg if its as simple as removing the intake mani spacer.

The came gears to increase VE which will increase mpg is sound, the manifold spacer creates a longer runner which creates more air head velocity which fills the cylinder more per stroke (as i understand it). Less air in (without the spacer) and a greater VE / longer burn with the cam gears SOUNDS like it should increase mpg, but who knows what it does in the real world with our bricks of tacomas.

 

interested to see what happens since I did both in one go also.

 

interesting theory and way above my knowledge of eNgInEs

@mightytacoman what are your thoughts?

 

It's solid in theory. Real world application is hard to say. I can't recommend for or against the spacer as I haven't run one and as of yet- nobody has data before and after the spacer with cam gears installed. Sounds like that might change soon though

 

Sounds like you need to test sooner rather than later...

 

I was getting 17 mpgs on 34.6 275/80/17 Goodyear MTRs on SCS Ray 10’s, 3.73 gears, heavy flywheel, cam gears, intake spacer and a JustDsm tune. In December I added 4.88’s and dropped to 13.5 mpgs. Probably a little to do with winter gas and now turning 2750 Rpms at 70 mph. I added headers a couple weeks ago and am getting 14.5 -15 now but haven’t had a chance to really get a good solid apples to apples average because of warming up the truck before taking off and not doing a lot of freeway driving like I normally do for work. I will say the truck runs killer and I have lots torque where I need it.

 

I thought final drive gears is supposed to improve mpg?

 

With 3.73 I was turning 2000-2100 Rpms. These 4.0’s sip gas around 2k. If I was 4.56 it probably would help a lot but I spend a fair amount of time in he hills and Mts.

 

Since Im going to be there, addressing the timing chain cover leak (not the full monty just the quick fix with external Permatex and bracket shaving) Why waste a set of valve cover/intake gaskets, put me on your list please sir. I'm in
Stiffy

 

Same. I remember installing my manifold spacer and not really noticing a big difference in any one aspect. Always curious to see data numbers from someone other than a manufacturer.

 

Another set of cam gears installed

 

How fast do you have the installation time down to now?

 

Sent ya a message on Instagram.......so wish I could have you do this for me!

 

How much do you charge?

 

Gio had me in and out in 4 hours not counting our rain photo shoot. I think that’s probably where he’s at plus or minus 15 or so. Once he gets the torque specs memorized he’ll be faster haha.

 

@Mista_G hit it right on the nail. I’m down to about 4hrs at a somewhat casual pace

Send me a private message, price slightly varies depending on what we change during the job (seals, spark plugs, etc)

The stories were slowing us down a bit too

 

Bump up. I'm shipping sets Wednesday. Anyone that wants to jump in without waiting long- it's a good time.
