Bad day on the dyno...

Watchin you go thru all this bs (and i've been watching your build for what 3+years now?) and it makes me feel better, cause i though i was the only one where sometimes it feels like nothing can go right. But when you think about the thousands of parts on our rides, it only takes ONE for something to go awrie!!!!!! Then the odds dont seem like too much....

Good luck bud!!! FRom sunny ca

We reinstalled the original pump that came with the Wegner front drive kit. It supposedly is not optimal for the AGR rack which I run, but it works, if just a little noisy.

Glad I can help you out there. I think most of us have a thrashing like this at least once. I just over documented mine this time.

:-)

Btw, nice job at the weather. It's supposed to rain the next few days and possibly the weekend! Hoping not...

Me too! It slapped the hoses and wrapped around a few things, but could have much worse! Just the time and aggravation...

TOW is home and parked in my garage for the first time in 2 months... Accusump is installed and appears to be working (charges, and pre-lubes). I gave up on making the wiring look nice for this week, but everything is functional at least.

Eric did some work to clearance the driver's side shock by modifying the Watt's link mount on the axle. It had been rubbing, which is not good. May look into replacing the shock body down the road.

Here's a couple of pictures of the Accusump mounted before reinstalling the fan shroud. It's really a tight fit in there (and some clearancing was required), but everything sits nicely in just the right place.

Time for sleep!

Congrats, Bryan!

Great to hear that your ready. It looks like a good spot for the Accusump.

We made it!



Eric and I were working until about 7:00 last night, charging the AC and bolting on the belly pan and subframe cross bar. I got her all washed and and loaded and ready to leave this morning.

The drive up was uneventful, which is the best word I can use! I made a couple of stops along the way, one of which was to AGR since they were about 1/2 mile off of my path. (they will be replacing the PS pump, and apparently I need one after he showed me the metal floating around in the fluid of my current one) TOW drive great up the highway, smooth at speed. I can lug the engine down into the 1700 rpm range and it doesn't complain at all. Part throttle response feels better than before as well.

I haven't run it hard yet, just a couple of 6k+ rpm blasts. Tomorrow on the autocross course she'll get a good workout!

I did have one panic moment as I was driving to dinner. I hear something hit the firewall or the toe board, not sure which, but it didn't sound good. I stopped and looked everything over but didn't see any obvious problem. After I returned to the hotel, I grabbed a flashlight and started looking closer. I found one of my hose clamps had come apart, I must not have gotten it tight. The sound I hear was the other half leaving the car. I was happy this half stayed in place so that I could find it and relief my concern!



At this point I'm hoping the weather is going to hold out for us tomorrow! The registration for this event is apparently really low, as evidenced by my number above (I was over 1800 last fall). I think the forecast is keeping people away. We still have a good chance of at least 1 of the days being good though! I'm hopeful...

I think it's time to write the final chapter to my "Bad day on the dyno" thread...

I returned home last night from the Fort Worth Spring Good Guys event. 480 miles or so on this trip, and everything is running great still. I have a couple of oil leaks from the new Accusump plumbing which I need to correct his week, but outside of that, TOW is running very well!

Compared to the previous 402 which I was running, this engine feels a bit more responsive to the throttle, runs just as smooth down the highway, and spins up quicker than before on the autocross course. At this point I'm really happy with the combination which I've put together.

Here are the final results from the autocross event this weekend. I was actually in the lead through 3 rounds, but then Chris Jacobs showed up and clobbered me. My best run of the weekend was lost due to not making the stop zone, but it still wouldn't quite have been good enough for second.



It's time for some driver improvements! The car definitely has the potential for better times...

I still need to get the Holley HP setup tuned for the new motor. In the meantime, I've been learning more and more about tuning it myself, and at this stage it's running pretty well. I am curious what the dyno will show once we get that done.

I want to thank a few people from this forum for their help over the last couple of months: Tim, Steve, Eric specifically. Tim educated me on some options for what I could do to the LS7 which started me down the to that block. Steve and I have been bouncing ideas off of each other about the engine and our respective Accusump setups. And Eric for all of his work and pushing with me last week to get her together to make the trip. It would have never happened without his help and support!!!

Time to go wash all of the gunk off of TOW from the rainy roadtrip and get her ready for next weekend's USCA event.

Congratulations on a good first outing. Nice to hear it all went well for you and you had a good time and got home safe.

Congrats, Bryan! Really glad to hear the engine performed well for you.

Glad to hear the new engine works out for you. Hope to see you and Steve (gerno) this weekend at USCA.
