Track Worthy?

Recommended Posts

Hoping to make it out to Streets of Willow, but this is a little last minute for me. I bought my 85.5 NA a year or two ago to use as a car for DE events and maybe spec or cup use if I can find the time (and money... and convincing of the wife...) it just hasn't happened yet. What are the important parts to check to possibly prevent my car from grenading at the track? Is this the type of event to try out the car? I've done a track weekend at streets in another car but I assume with no mods I should be in the slowest group (at least to start?)

 

Thanks!

No worries, Jay. This is an entry level event.

Make sure the car will pass tech and you have enough tires and brake pads to finish the 2 days.

Bring extra oil. I fill it over the full line about 1/8th inch. Don't rev it above 6200 rpm, there's no power up there anyway.

Nice to have you on board.

If your wife needs convincing.................well, get creative.

Do you need anything to get to the event?

 

You can keep the car street legal and race it too. Drive it to the events. I do.

Don't listen to Timmy on this one, it's a phsycological advantage he's trying to get on you. I listened to this little (Timmy) voice in my head at the big track (Willow) and would always shift around 6,200. then one practice day I tried to ring it out further (do so at your own risk) and it made at least a 5 mph difference from the point of shifting to reaching the end of that section of track (i.e. entering 9 and entering 1). So, for many races I had been giving up that 5+ mph to that little voice. It's not to be trusted! heh heh.

 

Have fun with it Jay, bring it out and have some fun. As a newbie you would start in the student group with an assigned instructor anyway. Someone to hold your hand (not litterally, except for Eric) through the day.

Dilly,

I too shift at 6000 to 6200 rpm. Honestly I do.

 

In MY car I have not found there is any advantange in going farther in the RPM band. All it means is more wear on the bearings and such. Plus its much easier for my to shift when the tach hits "6" rather then some other point.

 

 

Jay,

Come on out. Make sure you have oil and keep the level full, Make sure you have good brake pads with plenty left. Also bring a water for the car just in case. Next tip is to pit with spec guys since we can diagnose and any minor issue or concern you may have.

 

 

PS... Just so you know we are not all sex crazed mainiacs like Eric, and Dilly. Anyway their really not that bad.

Eric and I just like to spice it up a bit.

 

Really, you only shift at 6K also? I experimented at Willow, obviously a track I've had enough time where I can measure the difference it makes. And that difference, is about at least 5mph (I was thinking 10mph but my memory just doesn't work so well) basically from my shift all the way through to braking (well, lifting) for 9. My peak hp is at 6K but, I guess holding on a little longer above 6K is better than shifting to 5th and the revs dropping? Maybe I should dyno my car in 5th to see if there is any significant power loss? What do you think? Is this odd, has nobody else noticed this issue? I'm confused now. Talk to me.

OK... Talked to my mechanic today and scheduled a belts/waterpump/seals job for early next week. It was getting to be that time anyway and with the revs I'll be seeing I'd rather be safe than sorry. Other than general maintenance I needed anyway, the only thing I don't have (I think) is a fire extinguisher. Looks like a requirement from the tech page and rec's on what to get and where to mount?

I was starting to think I'd never get this thing on the track.

Where can I find more info on the Streets event. The #51 Darth Vader Car has new control arms, etc. and is ready for some track time... I do not have a racing license as of yet, and probably won't be able to make a class until January. Will I have to have an Instructor? I only have one seat, and unlike ALL the other Auto only tracks, I do have a few race days at Streets. Dropping into Talledaga at 100MPH while bump drafting in a kart is a religous experience. If someone could give me a phone number, or URL, I would appreciate it......

Dilly,

I really do shift at 6000 to 6200 rpm. After seeing my dyno sheet there's no wondering about it. There's no power up there with the stock cam. Torque really drops off at 5800 and hp drops a little later. You're just smoking your bearings! Also, if you rev that high you might be starving your bearings of oil.

If you think you went 5 mph faster down the straight, it was your exit speed from the last turn. Remember, I wanted to get 4 or 5 HOT LAP timers stationed at different points around the track so we could see section timing?

I'm sorry to say guys, I know what I see. I do/did it lap after lap. And Lap after lap it was the same story, regardless of exit speed. I gained more speed at the end of the straight, holding it out longer in 4th? Which "started" with 5 mph faster when I selected 5th from 4th.

I see your point. You start usage of 5th gear at a higher point in the power band. But aren't you losing some acceleration by leaving it in 4th longer, where there is less power?

Is your car chipped?

Headers?

I wonder where your hp and tQ peaks are?

My car makes 130 ft lbs of torque from 2500 to 5800, then falls on its face.

No chip, stock header, hp peaks at 6K rpm. But as I start to turn in for 8, my top speed is visibly different depending if I have shifted sooner or later in the rev range. And I'm talking consistant lap after lap top speed, shifting at 6K versus 6K+. It's not "sometimes", it's every single lap.

I believe you when you say your experience is real. I just can't explain it and it may be specific to your car because of your combination of components.

What does your dyno sheet say for torque drop off?

p.s. Can you drive up to the Streets event one day for a group picture?

I don't think I need anything (except as much advice at the track as I can get.) My paper work is in for the POC and for the event. My helmet was only DOT so I ordered one that was SA2000 which should come in by Tues. I asked about the fire extinguisher and was told it was only reccomended (may pick one up anyway.) As far as the car, I'll know Mon or Tues if it'll need more than a belts/pump/reseal. Assuming there aren't any suspension problems that would make the car unsafe I've decided to put off new front struts until I have a chance to see and talk to all you guys at the track. I can't decide if I may want to go all out suspension wise and just DE the car or keep my eye on the spec class. My mechanic can tech PCA but not POC so I'll be there early Sat AM.

See you all there!

Eric Sorensen and myself will be there on Friday early. I'll help you through tech.

We are there to help you and your 944. This 944-spec class (944 GSR in the POC) is a great, friendly, helpful class. You couldn't have picked a better class to learn the ropes. Each club is a little different, but you'll like them all. Promise.

ps. bring spares to the track.

Good man, Jim. It all helps. Whatever you can bring is fine, up to and including a tranny! Water hoses, coolant tank, electrical parts, plugs, wires, DME relay, wheel bearings, suspension arms, whatever. The cool thing is that we all have basically the same car.

Also, bring fluids; oil, brake, power steering, CV grease.

Oh, but keep the grease away from Eric and Dylan. For some reason, everytime I race with those two, I notice my supply of CV grease goes down some. ? Funny, they never have axle problems..........

Now THAT's funny sh*t.... Question: Do we know of anyone who may want a used Autopower Bolt-in Rollcage? I may have a opportunity to get a pretty cheap weld-in, and I was hoping to recoup some of the $$ on the bolt in.... Any idea what it is worth????

 

Today, I get to see if the 944 will fit in the Kart trailer......if not, I need to start figuring out that piece of the puzzle as well.......

 

Back is getting better daily... I would say I am a month out.....

Jim, great news on the back situation. DON'T PUSH IT. My sponsor John, at BLACK FOREST got a little too encouraged with his back progress and put himself behind schedule with his rehab. DOH! I really want to get him out there in his # 77 yellow car.

I might be interested in the bolt-in roll cage......

 

Also, make sure your cage guy READS the NASA cage rules. They want 360 degree welds around the tubes and there are other minimums and angles and such.

I don't want you to get to the track and find out your cage won't pass tech. NASA will fail you. I've seen it.
