Thanks for that! My car sure could use a new one, you’ve got a good looking GEM there, cheers

Looks like they got that out much more humanely than they did mine. Good thing I was already planning for full restoration paint job inside and out! Lol

yeah it went pretty smooth. It did crack a little bit when he went near the cracked areas but it didnt explode or anything like that.

I feel like the boy who Cried Wolf with this boost control issue. I was doing some more troubleshooting and testing of the boost control to try and get back to where i was at on boost Ken said to set boost cut at like 44psi and pull the boost reference line off the turbo and cap the port on the compressor housing and basically just let the turbo eat and makes what it makes.
So i tried that and the car made the same boost as it did with the wastegate connected which was 37psi.

I got the new replacement turbo in place of the rebuilt unit that i rebuilt and threw on the .83 housing again too.

I also decided to pull apart the wastegate to check that out and at first glance it looks fine and i cant see anything. Decided to just pull the diaphragm off the valve of the wastegate to 100% make sure it was okay and found about 6 holes in the diaphragm. Not like poked holes but the rubberized / teflon material had been like peeled off the fabric layer of it. Super weird.



So my theory of what is happening and why boost control basically isnt working is this:
With holes in the diaphragm, both the top and bottom ports are now seeing the same pressure so they are equalized and cancel eachother out. The EMAP is now the restricting factor and is what is capping the boost by pushing the wastegate open at that EMAP pressure. (17psi spring) but the wastegate cant vent ALL of the pressure from the exhaust. Just remember that boost pressure does NOT equal exhaust MAP (EMAP).

I believe this was also the case when disconnecting the boost reference line and letting the turbo make what it will. Boost was limited by EMAP. Anyways so a new diaphragm gets here today and after this weekend I can get back to testing boost control and see if that fixes the boost control.

Send it to the MOON

Got the car back together and had our car show which turned out pretty good! I got stuck in a corner away from most of the main traffic which seems par for the course for some reason.. none of the photographers took any pictures of it either which always happens too

Anyways, I got around to getting into some boost to test out the new diaphragm and it seems to be working. I had the duty cycle to like 30% and it was making 40psi on 3 separate 2nd gear pulls.

I added a 2% duty cycle at peak boost and added some more to spool up a little faster. Haven't had the chance to drive it since doing that.

I will note that it was probably the roads and tires not being warm but it was still spinning all 4 on those pulls with these Hoosiers

What tire air pressure do you have? Maybe you should drop the pressure if they spin. I ended up around 18~20 psi for streets and somewhere between 10~15 psi in the track for that reason when my 1g had the hoosier drag radials. It made a huge difference.

I think it's like 26psi right now. I'll look into lowering it

WE ARE BACK BOYYYSSS:

Diaphragm was the issue.

Took some time yesterday to find the source of another transmission leak and I found it. It's the speed sensor on the transmission. My setup is a little unique because I have a Brantz motorsports speed sensor coupled between the transmission and speedo cable because Link ECU does Not like the EOM speedo output for whatever reason.

I know the factory speedo cable has a seal in it. I looked into the bottom of this Brantz sensor and it didn't. I don't know if it was supposed to have one either. I tried stuffing an oring the same size as the top lip of the sensor threads on the transmission into the Brantz sensor but I think it made it worse.

Then I pulled off the seal / sleeve from an old bad speedo cable I had and threw that in there but I'm not holding my breath. I can't tell if it's leaking from somewhere else like inside the speedo sensor itself or what.

Haven't driven the car since trying to fix the speedo leak. It's been raining on and off, been busy with helping family projects and the car needs some fuel.

They re-opened our 1/8th mile drag strip in Sturgis, SD so I'll be going on the 29th and see what we can run! Only about a 30 minute drive. Idk what it'll run for times, I'm hoping a mid 6 with all the new found boost and if I can get a decent 60'. Hoping to trap close to if not over 110mph but we'll see!

That’s exciting man good luck

Maybe some Teflon tape would help?

Stoked to see you get it on the track with lower psi on the slicks! Whats the date code on the tah'rs?

Instead of an o-ring , try one of these gasket seals. I have an electronic speed sensor from a montero and it has one of these teflon seals.?

Thanks this is what I had in mind. It's also very similar to what I put in there from my spare speedo cable

Boys we were RIPPPING last night at the track. Got kicked off for no fire jacket and no rollbar/ cage.

New PBs all around. I finally got the slipper somewhat dialed in, as well as launch control for the most part. Probably a little too aggressive but oh well it worked out and ran a 7.03 @ 111 ( according to the timing system)



Slips (left lane) dragy for comparison


The track was having some odd timing issues. My 2nd pass I managed to double clutch off the launch and killed my 60' but still ran an 8.05 @ 110 according to the track timing system.. but dragy showed a 7.19 @ 110 and like a 1.89 60'.
Other people had really odd times as well. Some matched dragy and some were way off.

I unfortunately most likely won't be returning to the track anytime soon since I'm not going to cage or even roll bar this car.

Anyways, SUPER successful night. I trapped what I was hoping I would. There was a Dodge Demon there trapping the same MPH but running 6.8x so I'm happy with my result.

Hell yeah man that'd really impressive

Congrats man that’s awesome! Looks like that Anfurney Built stg 3 trans is holding up nice

That MPH is absolutely solid! Def capable of a low-mid 6 at that trap. She is moving!
