Hey guys wanted to make a little database of Lap Times @ Harris Hill. It would be very useful if you would specify the car, mods, direction, and weather when the run happened. Of course video would be great as well to help other members improve but if its not possible thats ok as well. 

 

Ill start with a sample format, copy it or make your own its up to you.

Don't think I've broken this one yet:

 

1:37.7 - 2010 Mitsubishi Lancer GTS (CVT)

 

Direzza Z2s, Porterfield R4-S pads, Fluffy Bunny in rear seat.

 

No actual mods to car itself unless you count Fluffy.

 

(That was in February. I don't time myself often.)

Wheels & Tires: Stock 15" wheels, Star Spec tires (the original ones)

This is our ChumpCar, so it's gutted and caged.  One of my teammates has run a 1:33, but with stiffer springs.

 

First complete lap:

It's frustrating, as I keep lifting out of it between 8 and 10 due to the pavement being so bad.  I'm at about 100 on T8 exit, but then end up at about 75 mid way through to T10.  That and T2 has gotten worse, or at least that's what my memory tells me.  I know there's a lot more time in there, but pulling a 28 with those caveats isn't too bad, but I'd like to see in the 25-26 range.  I hope they get the surface smoothed soon.  It's a fun course, but the quality of the pavement is terrible at best.

I don't think I have data from this lap but I do have video I'll dig up and post.  Although I'm not sure the video will help anyone unless they are trying to learn how to go slow:)

Ah, but a vid would be the tool for instructors to give suggestions.

1 is fine.  Little hop sideways just after two, but I'm pretty much into track out by the time I hit that dip, so while it is a little disconcerting it's not a lap-killer.  Didn't notice any issues between 8 and 9 really - are you coming to track center to turn back right for 9 or are you staying inside from exit of 8 all the way through to track out for turn into 10?

The only place that's particularly problematic for me right now is the bump in the front straight just after 11 ends.  Almost lost it there last weekend :)

I was driving my buddy's stock 350Z. I think going CCW is pretty durn fun. My buddy was running 1:33 lap times his first session. Then I ran my session in his car. We went back to the clubhouse and analysed the data. My buddy then went out for his last session and ran a 1:30.94. I was really impressed that he could take what he learned from the data and apply it to the next session.

My car is too low for H2R, so I had to slow down for 2/3 &/or go really wide to avoid the bumps.

Car: 1999 Porsche 911 3.4L SP996 racer

Aero: GT3 Cup front splitter; Getty Design GT3-style rear wing

Engine: Stock (270 rwhp)

Car is a race car so interior stripped with full cage.  Weight with driver is ~2950 lbs.  My estimate is there is probably a 1:22.x with fresh stickers and in more favorable conditions but it won't go much faster than that, at least with me driving!

Ergo,

 

That's a really good time for the current track pavement condition.  Looks like it was driven last July?  Mind posting up some vids so I can see your lines.  My typical lines are filled with bumps based on the last outing at HH couple weeks ago.  Haven't driven it since last year till then.

Hi brakelate

 

Thanks.  The lap was done last July on a very hot and sunny day.  The tires were coming to end of their life but still had decent grip for one last heat cycle or two.  They completely fell off the shelf the next time I came out a few weeks later and I couldn't get within a second of that time again.

 

Unfortunately the link cable that connects the Traqmate and my GoPro was MIA that day so I don't have video of that run.  I can try to post up a plot from the GPS data if that helps. 

 

I have new tires on the car right now but I'm saving them for a race I have in Dallas next month.  I plan on getting back to H2R afterwards to see if I can improve the time before track temps get too cold.  I'll make sure I get some video when I do and share it with you.  If you plan on going out sometime and if you give me some warning, I'll be glad to meet you down there to talk with you about how I break it down, for whatever that's worth.

 

Regarding the bumps, yes they're definitely an issue.  My car is fairly stiffly sprung with 700# springs in the front and 900# in the rear.  I have the dampers on a very soft setting front and rear.  Basically I just trust the tires and try to hang on and not let them affect the line too much.  The car hops a lot on the bumps on the straight between 3 & 4 but you just have to keep it matted.  The bump at the apex of 6 isn't any fun, but it's never upset the car too much.  The bump at the exit of Dam Turn is probably the worst because the car is really loaded up at the exit.  I sometimes don't track all the way out there depending on how the car feels.
