9s for $9k

Just sipping… waiting on an up date.

Mean time Jim we gotta head back to the track this morning. Gene struck a deal yesterday to buy a 70 Chevelle. Now the complex part. Getting two cars back home on a one car trailer.

 

That conundrum reminds me of my demolition derby days. We would sometimes buy a competitors car and then need to figure out how to get it home. Usually we stacked them on the rollback

 

Just got to negotiate the price to include delivery!
Tucson to LA is a fair bit, at least it's not too crowded and is fairly cool this time of year.

 

There’s a plan in place.

 

The racing was a bit odd, I only made it to the second round...but it was fun anyways.

We drove home this morning. I guess driving a car to the strip, running low 11s and a high ten, then driving it home, is still an accomplishment.

Fun time, met up with a lot of friends and my throat is sore from all that talking I did all weekend.

I'll see if I can get some more pics and possibly some video up.

 

6 hundredths, ouch!
Glad you had fun and everyone is home healthy.
No dial, pro tree? Low 11 to low 12, weather, track or tune?

 

let off. On the last pass, the pairing didn't work out like the guy at the back of the staging lanes wanted, i was supposed to race the Maverick, but everyone went into the wrong lanes because it was hard to see where he was pointing. Then I was paired with a 9 sec mustang...I did a burnout and got close to the tree, but was waved to not stage yet. The temp light went on, coolant was at 121, which was strange, I had no idea why. The mustang never pulled up, apparently something happened to it in the burnout, and I couldn't see what was going on, but they pulled a ranger pickup into the other lane. And the pro tree thing, I was still expecting sportsman, so I left a little late, but quicker than the ranger, so I never saw him, I was still expecting the mustang to zip in front of me. I looked back and saw the truck back a ways, and let off, but too much, he caught me at the finish. Oh, well.

I got to watch the rest of the racing, and talk with friends Matt and Jon, who I've done some LeMons Rallys with. The flew down to spectate.

 

Since Gene’s Nova did Death Week when you did it in Plan II why not drive it to my house? Market Place purchase Saturday night for tires and wheels for up front and the drag radials it went to the track with, my Son jumped in it and away we went.
Got to the house no problem.

 

I’m curious what rpm is LS turning at 130 mph or whatever it is running for mph?

 

Here's a bit of datalog from that run. Looks like 6170 rpm through the lights. The dark background makes it hard for me to see the lines, I wonder if I can change that.

 

How hard do you want to turn it? I’m not familiar with the LS enough to know it’s limits.

 

they say they're fine up to 6500ish, some guys say they're fine to 7000, with stock rods.

the big concern is too much compressive load on the rods under boost, so it's good to rev it higher.

 

What is your converter’s stall speed?

 

3400ish. But it depends on how much torque is trying to go through it.

 

Do you have boost at 3400 and do you have an electronic boost controller?

 

If you look at the datalog (click the picture to make it bigger) you can see zero boost (brown line) at the launch, then it slowly builds up, and about 2 seconds in it's up to 10ish psi. Then gets up to 13 in 3rd gear. (look at the red RPM line to tell what gear it's in).

I don't have the computer controlling boost, yet. Having the computer control boost would let me limit it, but won't force it to make boost.

To get boost at launch, I need to spool up the turbo, and doing this without a transmission brake is challenging, because the engine makes so much torque at 3400 rpm that the wheel brakes won't hold the car still.

 

A trans brake would help but as I'm sure you know, that starts a long process of fixing weaker parts!
I'd look at playing with the 2 step to cause fuel and air to hit the turbine, although that can probably find weak parts too.

 

I started playing with the 2 step, but haven't found the magic combination yet. I'll keep playing with it.

 

If not wanting to use brake , Spin it up with compressed air or Co2
On inlet (Compressor wheel propeller) , with RPMs switch @ like on @
3,550 -3,600 then kick off like 4,000
With in 60 ft ish .
Or turbo change .

 

I don't know if anyone else understands what you guys are talking about, BUT I'm learning a lot of stuff I have had no interest in before. Thanks to you guys for explaining things. Sometimes it sounds like Greek, but trying to keep up.

 

Proof positive, that an old @squirrel , can teach a bunch of mature gear heads new tricks!

​

 

...and I'm learning as I go!

That's how to learn things, dive in and try it. Maybe you'll figure out how to make it work, maybe not, but either way you'll know a lot more than before you started.

 

I was spectating at Dragway Park Cayuga in (I am guessing) the 90's. I was with a friend who knew Al Billes (former Pro Mod driver and present day tuner) so the two of us hung around Al's pit/trailer. During eliminations, Al's car got out of shape/out of the groove just off the line. The other car hooked and left. Rather than give up/admit defeat, Al got his car straightened out and got back on the "loud pedal". The other driver, had issues of his own at the top end, let off and apparently figured he'd coast to a win ... not realizing Al was charging hard. Al caught the other car just before the finish line and won. Al had it on in-car video tape and we were able to watch it back at the trailer. I fully understand the other driver (probably) figuring "there's no way I can lose this" but ...

 

Never let off until you’ve driven well past the back door.

 

Seen several races lost because of that attitude.
From T&F events, to cyclists celebrating stoopid early, and even a few track events where the leader let off not thinking anyone would be able to hard charge past them. Others determination can wreck your day when you get lax.

Saw a bit of a Nascar-esque wreck the other day, one car was a Volvo S60, it was spinning, had its front bumper ripped off, hit something in the road which stopped the spin but the car threatened to pirouette on its back bumper. While all this carnage was going on less than a 100' in front of me, near a school zone, I could clearly see some radiator ducting on the front of the dancing S60, and my first thought was,
'I wonder if that ducting could be used on Jim's Cheep.'
Volvo came crashing back down to terra firma with some surely squared wheels.

So Jim, next time you are at a yard, if they have any 1st gen Volvo S60s, look at the bumper to core support for any radiator ducting. If cheap enough it might work for Cheeps intercooler.

 

A little shot of nitrous off the line will wake things up ( big smile).

 

Unless you’re bracket racing, lol I got pretty good at resting my Lt foot on the brake pedal just enough to show the brake lights at about a 1100 ft when racing a faster car…
