Trans cooler and lines are done and several little odds and ends are fixed. Just need to fill with water and trans fluid and fix the leaking turbo return line and we will be ready for a test drive. This Friday is the last scheduled TnT at our local track and we would love to make a pass or two before we go to Ford Vs. Buick at Thunder Valley OK in October!

Car runs again but we did not make it out to the track. Too much stuff going on right now and it still needed a few adjustments. Mainly the shifter. N is where R should be D is where N should be... etc. Trans does work though.
Neutral safety switch is also wack. You have to press right on the shifter to get it to start. Haha.Life is short. Be a do'er and not a shoulda done'er.

Whoo hoo! It moves and stuff!
We started the evening by removing the drive shaft and swapping in the drive shaft from the 1998 GT. The drive shaft I used with the big block was a little too short for the small block and aod combination and I was afraid it would vibrate. Besides I want to use that drive shaft in the '98 GT.
Seems simple enough, right? Well the transmission yoke for a t45 is larger than a T5 or an aod. It's the same size as a C6. We didn't discover this until we started putting the drive shaft in and it wouldn't go in the transmission. So, we had to back up, swap transmission yokes and run to the store to get a new u-joint before we could put the new drive shaft in.
It fits much better than the shaft I used with the C6 and big block.
Next we monkeyed with the shifter to get it adjusted properly and I think we probably got it really close. It's still not as notchy and solid feeling as this shifter did with the C6 but I think that's more because of the internal rooster combs are different between the two transmissions. The selector lever on a C6 is pretty hard to move with just your hand and it's pretty easy on the aod.
Once we took care of that, we fired it up on the jack stands and shifted it through the gears for a few times. Then we put it on the ground and Judd pulled it out of the shop and made a few laps in the parking lot. I think the fluid level is a little low but the car moves and shifts and generally does the stuff it's supposed to do.

Went out, pulled the trans dipstick. Nothing. Endsd up putting 3 qts in it and it works great.
May need to do some carb tuning with the different intake. I went for a short drive and it was stupid rich at first but seemed to get better thw longer it ran. Might have just been partially clogged from sitting for a few months.
First impression: it is completely different. the automatic feels different, the turbo reacts different, the motor runs different and it seems to hit the rev limiter very quickly. I may have to bump it up 500 RPMs just so we're not banging into it all the time.
I also think I need to back the timing down because we're loading the motor a lot more than we were with the five speed so it may be more prone to detonation. I don't want to screw up and break it before we really get to play with it.

Drove it home at lunch. Fuel pressure is too high. Not sure why, but it was definitely way way way too rich. Trans seems to work good. Floor it and It will down shift and haul butt.

High fuel pressure: This has been a problem ever since I put the fuel lines in this car. I put a -6AN return line in and it is just too small. With the big block, I crutched it by using 2 regs. An Aeromotive bypass reg set at 15 psi and then a Quick Fuel dead head reg after it and over to the carb. That kept the A1000 happy and I didn't have to replumb anything.
The n/a 302 just used a carb-style electric fuel pump with the QuickFuel reg dead headed, no return needed.
With the turbo 302, I had to go back to using the return line because we had to use a boost referenced regulator. It has worked sorta ok. The pump has an internal bypass that used to bypass at 6-7 psi. So I just set the reg begin increasing fuel pressure just above that. Now, for whatever reason, and even occasionally during Race Week, the fuel pressure will not go below 9 psi.
I'm sick of working around this issue that has been there for nearly 10 years. Haha. I ordered some hose and fittings to finally put the proper size return line in it. Should have done this a loooooong time ago.Life is short. Be a do'er and not a shoulda done'er.

Well I should have ordered 12 feet of hose instead of 10 feet. Luckily I had another 20-in piece laying around that I could use.
I removed the gas tank filler tube, drilled a hole in the side of it and welded in a -8an bung so I could connect the hose to it for the return.
Once we had the line ran all the way to the front of the car and the regulator connected, we turned on the pump, and we're able to set the fuel pressure at whatever we wanted. We set it at 6psi.
Then we started the car up, and it wouldn't stay running. Fuel pressure was 3psi and I couldn't get it to change. I asked Judd if the electric pump was running....... it was not. The switch was on, but the pump is not running. Crap.
The pump literally just died. Lucky for us we had a spare pump and we're able to install it and everything works good now.

I drove it around today some and did some carburetor tuning. It's still rich at low/no boost, high throttle angle situations, but once the boost comes on and you pull second gear, hold on because the back end starts wagging around and things start happening fast.
It's really crazy how a change of transmission makes everything feel completely different.
I need to figure out how to clean up the carburetion at low speeds because it's really really rich and misfires until it cleans up. But dang, it's fun when it clears up!!!Life is short. Be a do'er and not a shoulda done'er.

It's called "EFI" just kidding I know you can get it figured out. I got a cube shaped box on the front porch this afternoon!

This carb seemingly worked really good with the dual plane, 5 speed combo. It is interesting how different it acts with the single plane, automatic. I suppose there is a lot more throttle modulation with a 5 speed and that may mask some of the low rpm, high throttle input short comings.Life is short. Be a do'er and not a shoulda done'er.

Did some data logs and have been comparing them a little.
First one is just as it was with the 5 speed. No changes. 67/75, 6.5 PV, vent tube extensions. 28/29 squirters, orange cam
This one is 65/75, 4.5 PV, no vent tube extensions, 28/29 squirters, orange cam.
The 3500-5500 rpm section is a little steeper (2 tenths of a second steeper, prob from leaner afr) on the second one but the AFR starts to trend upwards hitting 12.4 when I shifted/backed off. The original setup seemed to trend richer, although not as significantly, dipping all the way to 10.4.
Interestingly, it looks like the original one shows the AFR to be lean when I first get into the throttle. That does not seem to match what I remember seeing on the gauge, but the log doesn't lie. Maybe this thing was misfiring and acting goofy because it was wanting more fuel, not less....Life is short. Be a do'er and not a shoulda done'er.

Today was a fun one. It is surprising the number of carb deficiencies that having a 5 speed/clutch can mask.
I took the intake hat and vent tube extensions off. Drove it and it stumbled and acted just like it had been. I started with 32/31 squirters and incremently drilled them to 35, 37 and ended on 39. That got it to not fall on it's face and actually spin the tires. It still is not right because it will launch, then build rpm slow then clean up and run good. Tried it with the tubes and hat on and it was the same.
Next up: going to baseline the idle transfer slot, and secondary plates, then block the primary PV. The low rpm bog seems to correspond with engine vacuum dropping below 6.5, the PV opening point.
I increased the PVCR's back when I did the blowthru conversion and I really think that was a mistake, at least for an automatic trans.
