1915 with AA 500 heads- now 2054

I'm sure it is hard to get off. I've never had one that isn't . And oh yeah, there is definitely pressure! Just ask my driveway! I used the full flow outlet to pour oil into the pump to prime it. Then i poured some down the turbo supply hose too for good measure.

did it turn over easy with the spark plugs out? new motors are tight to a certain extent

One thing I've done with my pulley over the years is a real light film of grease on the inside. It has always slid off by hand. Steel hub. Might be worth a shot. My engine was always pretty tight too. Big springs and such make them harder to turn over.

I did put a film of grease on the inside of the pulley. It might come off, but not easy I'm sure.
I will be back out there bright and early tomorrow to give it a shot.
The full flow cover is pushing the tin into the pulley too.
Hopefully i can get the leak fixed quick. I need to check the gap in the crank trigger and check the timing too.

What makes it feel “tight”? Helical or straight cut gears?

[buguy]

For me it's definitely the rings. Although i was shocked at how hard mine was to turn over, even with no rings, when i put the rockers on the dual springs.

This was after the first start. I fired it once and only turned the idle up to keep it running. No tuning yet. A little rough until. I get the leak fixed.

Yay! The pulley came off pretty easy!
Rubbing here on the pulley.

Ok i got the leak fixed. But now i see it looks like the sump might be leaking at the case and the right side valve cover too. I also think i see some wetness around one of the push rod tubes. I was just running it so i will let it cool and do some cleanup and check again. It's jacked way up in the back so there could have been some runoff. Sounds good though. Right off throttle not super great, but just a bit more and it wicks up fast! Can't wait for the first drive! Hopefully those brakes work!

[Schweg]

Glad your getting it sorted!

Curious to see if it’s as altering as EFI

[buguy]

Better get your wallet out Schweg! Just took it for a little ride around the neighborhood. Didn't do much because i have no hood, which means no license plate, and well... A neighborhood. She's really snappy! Really really snappy! Feels like a mountain of torque! I took a quick log and it started making boost at 1585 rpm at 37% throttle. Guess i better get my wallet out too. That's gonna mean too much heat, aka need a bigger turbo. But again, it was just around the hood in mostly second gear. Maybe i better throw the hood on and go for a more legit ride. Brakes seem to be ok.

[Schweg]

I’ll wait for a full test drive.


But seriously!?! That good?

I have a holset turbo just waiting for a 2l.

I’m just not in love with the cost. But if it’s as amazing as EFI I’m gonna have to break the piggy bank

[buguy]

Yeah man it's that good! It sooo much faster off boost. I have the boost controller off so i limited it to 14 psi. What's odd is that i hear the BOV like mad, even making very little boost. I have a feeling that has to do with the heads? Maybe boost was going back past the valves before and back into the engine? I only went for one more ride in it, but it felt nuts! Trying not to get too crazy just yet.
Unfortunately it has to come back out. It's leaking pretty bad from what looks like the 1/2 cylinders. I can't believe how much better it feels. More linear i guess. I had more of a surge in power before. Now it jumps and just goes like hell. I don't feel that big rush of boost anymore.

[Schweg]

Well damn!

I thought I was set on a simple 1600 budget build.

Sucks you have to pull it again. Worth the work of clearancing the case?

The blow of valve may just be fluttering due to a larger vacuum signal then before.

[buguy]

Yeah it's worth it now! But i won't ever go through all that again! It will be a new case for me on the next one.
I will always wonder what my 1600 would have been like with some good heads though.
I think it's all the extra power off boost is what is making this feel so good. These AA heads aren't particularly good, 1 3/8" header is a bit small, turbo is nothing to Wright home about, but it's still super good! So far at least.
I don't think I'm making anymore vacuum than before. I feel like it's just tighter and when i close the throttle the air has no choice but to come out the BOV now. It didn't even seem like i need to be in the boost for the BOV to flutter on the last drive.
