Hackster's Need for Swede 😁

[rustomatic]

I think they figured this heat range out with the 1992 LT1--I remember bugging out seeing a new Corvette get that hot in a smog shop I worked in back then. The LS definitely continues to like it some heat (excuse language--I am in Georgia right now) . . .

More and more reading on this topic and this is where I am looking to land. In Vegas it was 220+ and I was a little worried about it. I think the cooler stat is going to do me good.

Seriously though, the breakage is a bummer, but you are doing it the right way: using it. Good work on that, and good work on proving me right in the sense that softer springs are better . . .

Your newfound grip (nice camber setting!) may require you to engineer a more stout rack and cooling setup. I don't envy the research requirements . . .

Thanks man, Yeah I am a nut job what can I say. I am happy to be using it, just got a little frustrated that this stupid steering is what is going to kick my ass is all.

I believe that the "rebuilt" rack is my problem.

You crack me up.....whats in Georgia?

On a brighter note, Turn One was great so far, parts are shipped out and I should have them on Tuesday in time to get it back together and make it out to the SCCA Time Trials at PIR. As long as everything goes back together and no leaks I should be good to go.

I ordered some PowerFlex race bushings for the front, that is about all Ill be able to get done this coming weekend, still out of town for work until Friday night.

Did a terrible job of taking pics.

Could not give up a perfectly good (Sunny and dry) weekend with the car sitting missing parts so I got a parts store rebuilt pump and threw it on Saturday to see how things were working.

Bled it, put in Royal Purple fluid in the system this time. Drove just fine around the neighborhood so I loaded it in the trailer Saturday night and got my **** ready to go.





Went to McMinnville to run autocross with the BCA club. Great club, really good event.

Rest, Run, Work schedule. 70 cars in total, Raw numbers I am mid pack at 35.

Got some good testing in. Steering did the same thing.....its not the rack, believe it to be lower control arm bushings moving around under the car so I will address that this week.

Front brakes are too hot, I am locking up the front brakes on corner entry no matter what I do......I need to learn to be a better driver.

Temps were running right about 200 sitting around. We got 8 runs in less than a 2 hour run time so we were pretty fast moving. I was happy with these temps and didnt think I had anything to worry about. Temps were in the high 80's, just under 90 and we were in the sun from 7 am to 4 pm when I left.



I definitely need to work on the driver more. I feel I am overdriving the car and need to work on smooth before I work on fast. That is a very tough balance and I am still very new to the car as well as autocrossing. I know that there is more in me, I feel like I need some instructor time to help me pick up the pace.

Hope I am able to get the car dialed in before next weekends SCCA Time Trials.

Seems to be the most normal pose for the car, might as well take a pic of it.



Couldnt stand not knowing what was going on under there so I jacked the car up and got to work. Finding it was easy. Jack car up, wheel moved....

Grab wheel, the front lower control arm mount moves about 3/8" or so. I start digging further and the "stover" or lock nut is loose on the bolt that holds the lower control arm. Not only is it loose on there, its loose like you can thread it like a normal nut onto the bolt.

Also the hole in the crossmember is 14mm, while the bolt is a 12 mm bolt.

So here is what I came to the conclusion of, Replace the lower control arm bushings with the race superflex ones I ordered. I drilled out the sleeve for the front lower control arm up to 1/2" and ran a new grade 8 bolt with a new stover nut on it a little lock tight and it should be good. This was a much tighter assembly even when things were not tightened up unlike before.

I got one side done last night. Still need to do the other side tonight. It took me a little bit to figure out what I was going to do to fix it.

The hole in the crossmember was not egged out either, it was still perfectly round.

I am sure that I screwed something up somewhere but this is what I have now, should be better than stock in my opinion.

The good news is I can have the lower control arms out of the car in like 10 minutes now after doing it so many times. :roll:

Race, break, fix, rinse... repeat

Keep at it!

I can't imagine the feeling in the steering wheel that movement must have created?

You do realize that each time you make a fix like this you are going to have to learn the car all over again, right?

Nice work!!
