403 LS2 FD - LS7 Build for 2020!

[cholmes]

There's a technical term for meters like that: "Firearm practice target"

Has anyone looked at the PWM regulated alternators that are on the later gen4 cars and trucks? I don't really understand why the alternator fails when spun too fast, but was curious if you had manual control of the regulator if you could prevent it.

I use a 2 wire 250A unit from JS Alternators. Very happy with the unit. My ECU(Maxx) is controlling it. I was having the issue where initial charge was enough load to bog or kill the engine. Maxx didn't have a way to ramp in the pwm duty natively so I emailed them. It has it now. I have the duty ramping in over a 60sec. I also have the second wire on the alternator wired to a digital in. It's a 0-100% load monitor. Works quite nicely. Just made a math channel where 100%=250A.

Short day working on it yesterday but a fun one for sure.

Mocked up the catch can where the ABS was, I am excited to get that built.

I need to build an I/O harness for the Holley and tidy up the rest of the install and I think it’ll be about ready for tuning and break-in miles!

Hahahahaha

I noticed the tach seemed a little limp. Also, what rear gear? I had forgotten how tall a 2.66 first in the trans was.

[MPbdy]

I just swapped to 3.73's because I couldn't get a 3.90 aftermarket gear installed that was quiet. Went through a few sets.  3.73 ford racing gears should be silent (I hope).  I'm not thrilled about losing the gear multiplication, but my new trans has the shorter overdrive ratios which helped the mental gymnastics of being OK with the move to 3.73's.

There's no wire connected to the tach at the moment haha.  I have a steering column mount for the Holley digital dash that will block out all the gauges except for the fuel gauge.  I'm thinking I'll leave the tach disconnected.  The speedo is GPS, but I have a speed output from the trans for the Holley.  I guess I'll keep the speedo active so my odometer will continue to tick up. The insurance company likes to see that sometimes.

I like it

Sounded real good in the video!

Thanks dude!  Also, congrats on your 1/2 mile results!! 195 is flying.  I was watching your stories over the weekend.

I'm getting more optimistic on this engine the more I run it.  It seems very smooth, quiet and happy.  Not bad for a $5500 takeout with rebuilt heads.  Hard to even get an LS3 for that price.  I'm very happy so far with the cam I spec'ed when it comes to idle and sound level.  I haven't done any real tuning yet either its still just a base tune I slapped together.  We'll see when I lay into it if I wish I went bigger on the cam.

Looks real nice, but im ready to see it drive now 

Hold on, I get my clutch review first LOL @MPbdy   

@kinger the clutch worked lol! It had a small shudder on first takeoff. Take-up is smooth and natural feeling. Pedal pressure is about what I remember with the RPS and my Monster twin which is not too stiff, but still stiff enough to cause a foot cramp when driving in rainbows lol.  This is with the clutch spring removed.  I expected it to be a little lighter, but it is within expectations.  I put it in 4th at about 30mph driving up the hill and it lugged the engine a bit and the tune surged - but you can hear a little vibration.  I'm assuming I hit the same trigger point as the other clutch.  I'll let you judge on severity but to me it sounds like a lot less.  Until I get the car actually driving and loaded up in 4th going up a hill I will reserve ultimate judgemnet.

There's your 30 second driving review haha!  Smash that like and subscribe to get notified when the full review drops

Starting out positive!  No sound on the vid, check the mute button on vid and computer about 20 times couldn't get it to work.  Sounds like it may already be worth it!

Wow this was 9 years ago  Just popped up on facebook memories lol. These were the nights that I was out taking trips to Mexico with my wife before we were even dating






A little lackluster and boring on the updates.  Right after I got this thing fired up I came down with covid and was stuck inside for 10 days waiting to get over it, and then I had some work travel last week.  I did get up one day to work on it, but had to spend time fixing an issue FINALLY that has plagued this thing for so so long.  My dad noticed the trans was pushing fluid out again out the tail (this is now across two transmissions and 3 different tail sections).  Turns out the plug in the trans yoke was not sealed and was letting fluid out when it would get some pressure behind it.  It definitely won't be leaking now, and the car is back on the ground as it was before ready to dive into the wiring, but ate a full day of to drop the exhaust and driveshaft and get it put back together.

I will be heading up there today to try and come up with a plan to mount the ECU and start the I/O wiring harness I need to build from scratch.

[digitalsolo]

Hah, that'll stop it!

I also got COVID, also went down for over a week, and then also had work travel.  Do not recommend.
