🔧 BUILD LAME Turbo V6 Camaro

[bs009]

That's nuts that an air filter was that restrictive. That honestly might be why my HX35 sucked so bad for me, it had a really small filter to fit in the spot it was in. I'd like to see K&N start putting HP numbers on their filters now lol

At least some sort of cfm

 

[v6buicks]

While the engine seems to run great, the filter was not the cause of my smoke. It started doing it really bad on my way to a show yesterday.

I'm starting to think that the rings are giving up. ? I'll pull plugs tonight and order a leak down tester.

 

[Mr_Roboto]

You got to a point where it boosted its self apart.

Glad to hear you at least got some power from it. Having a restrictive inlet will increase your air charge heating and reduce turbo efficiency. The next question's going to be if you can turn it up or not. I thought you were hitting a wall boost wise, it's likely it went away now. Totally worth futzing with at some point.

It reminds me a lot of Turbo Mustangs where you'd hear about some rando guy cutting the Flowmaster off his build and gaining 40 at the tire. Ahh the olden days.

Sucks to hear about the ring blow by. I was hoping it would go away.

I will say I was looking on their web site and that drove me absolutely batshit. At least CFM or filter material area would be awesome for people like us who are trying to do things well beyond what a drop in panel filter does.

Do you have a bunch of blow by out the oil cap or in the catch can? Have you done a compression test? Make sure you don't have a miss or somethin too, any time I've had one that was even barely noticeable I'd see a bunnncchhh more steam comin out the can

 

[v6buicks]

Just got inside from taking stuff apart, but it's too damn hot. I might go back out and do the compression test when I cool off.

All plugs look the same, but I kinda expected that given that the E will wash oil away. These are starting to look kinda gross and dirty though, so it's probably time to change again.

See what I mean?

The catch can was full of water and corn casserole as usual. Very little to no oil.

On an unrelated (to the issue at hand) note, I started removing the coil wires so that I access the injector clips and noticed something really stupid.

How? Why? The. FUCK.

 

[Mr_Roboto]

All those horsepowers. May be time to hit that with the MIG a bit. Couldn't be in more of a pain in the dick spot to get to though. Out of all the shit on this I wouldn't want banging around too......

 

[v6buicks]

Oh yeah, Mr_Roboto I have not had a boost limit issue. You may be thinking of GTPpower. I'm just scared to turn mine up due to felpro head bolts and L36 gaskets.

 

[Mr_Roboto]

I may well be. Then again how big is his air filter?

Also, did it help you get into boost quicker at all? I could think the low end would be mostly unaffected but the top end got messed up so it wouldn't but figure I"d ask.

It's a cast aluminum bracket. I've sorta wanted to move the coils anyway, but I also kinda wanted to wait until I could convert to Holley and CNP

No filter on his. I still think it's because of the super thin adapter hat he made. He's probably boosting the snot out of that hat but not the pipes or engine. Hence, the insane heat he felt too!

There is some truth to that, maybe hitting the boost/exhausts with a FLIR will show him stuff he didn't see otherwise. They're a bit spendy even to rent but Home Depot rents them.

K&N dies their oil red so it's easy to apply a light even coat you are not looking to get it wet you are looking to get it lightly moist with oil. It doesn't take much for it to soak into the cotton.

Do not over oil and regularly clean your maf sensor filament until it's pretty well cleaned of excess oil by "large amounts of airflow to high rpm" or just go to the modern dry synthetic media and spend a little more

 

[Turbocharged400sbc]

Just curious but how is your PCV deleted on that? The f-body intake has some weird passages that you may need to take into account blocking off since you may possibly be pressurizing the crankcase through the factory throttle body because there's a fresh air feed from the throttle body through the upper intake and then through the lower intake

OG PCV plugged full of JB Weld

And throttle body passage pipe plugged.

That solved all my "blow by" issues a couple years ago.

Compression test results are in and exactly what I expected. Nothing noticable. Further investigation needed.

 

[Turbocharged400sbc]

Yeah but what about the passage in the lower intake? You could still be blowing pressurized air at the paper upper lower gasket in her face

If I recall it's right next to one of the port runners.

I can't remember what all is going on down there. I think the hole next to cylinder 2 is the throttle passage hole and the one next to 6 is the PCV passage?

I'm starting to wonder if the "corn casserole" in my breather hose is completely gumming up my catch can baffles. Maybe the oil is so broken down by the alcohol that I'd never know how much of each is in there.

For what it's worth, that tub of gross water I emptied had accumulated in under 1000 miles. That seems like a lot, but I know it's not mostly oil.

 

[Mr_Roboto]

Dunno if you saw this or not. Keep in mind it's stock heads too. If you do math on this engine without the cam it was making 115hp. With the cam extrapolating this I think he was nearer 160hp.

I'd bet the cam he used would net you 90HP at 15PSI and more at 20.

I was also just thinking about this, your CI/cylinder is the same as a 5.0L basically so you could likely use that as a point of reference in terms of picking a cam too.

I saw it, but it was long before I was in this predicament. I'll definitely need to re-watch!

My leak down tester is supposed to arrive today. Not gonna lie though. I don't see the results sparking any motivation. Life has been dragging me down a bit, and even the will to do "the fun stuff" like pulling the engine for heads, cam, and clutch swap is fading away.

Somebody buy me a shop and lift please. lol

 

[Mr_Roboto]

I'm wanting to head swap my 258 to a 4.0 head, thinking damn the cam just do it. I'm really just trying to rub in that it's only one head to swap not two. ?

Seriously though, stuff comes and goes. Just drive it and bask in your success so far. The weather (at least in Wisconsin where I am) is awesome in the evenings, even without A/C you should be enjoying yourself.

haha and that head is in the center of an engine bay sitting straight up.

I really should, and I totally would if it weren't for whatever the hell is causing smoke. I have a hard time living with stuff like that. I guess if the leak down shows no issues, I can blame the turbo and be happy again. If not, I'll have to make some judgment calls, and possibly gambles.

 

[Turbocharged400sbc]

Put a hose over your dipstick tube and run it to a vacuum / pressure gauge....
See what it's doing when it's smoking

Wouldn't he need to block the catch can off in order for that to work where the crankcase isn't sealed anymore?

In that case, I think you would be guaranteed to develop a problem you didn't used to have. I don't wanna do more crank seals!

Gauge on the dipstick will reveal a wild crank case tornado that may not be getting dissipated by the hole in one valve cover. At least I think that's the idea.
