Gimli videos: May 4-5-6 Hotlaps + School


Recommended Posts

I could only make it for hot laps but I figured I'd open the thread to anyone else who captured some video this weekend.Had a blast yesterday running laps in the S for the first time. Here's my quickest lap with data overlay (and Beau riding shotgun)... or at least the quickest one I got video of:

Data and video were both taken using Harry's Lap Timer Pro for iPhone. It was my first time using it and I screwed up the calibration a bit, so the video lags behind the data slightly.Thanks to Al and Chris for the pointers, and to the volunteer corner workers. Well worth my $60 (plus gas, plus tires, plus brakes... :P).

what are the gradients for the g-meter?

A new fan!!Hey all,I've been going out to the gimli motorsport park for two yrs now to watch the 1/4 mile racing, never even knew a road course existed. My Brother-in-law signed up for the school this past weekend and i drove out in the rain on sunday to check it out. What an awesome time it was, i may skip the 1/4 mile races and come watch you guys instead. I'll be sure to come check it out again at the end of the month. I have 2 86 rx7s, one may just become a road racer.Jeff.

pretty nice lap Jeff. looks like you took the school already
Thanks Brian. I took a school there in '99' date=' but I haven't done many laps since.I found out that autocross prepares you VERY well for road racing. Everything happens much slower on a road course, and car control is just not an issue; it's just a matter of learning the track, which I'm guessing will take me at least 150-200 laps.Another thing I learned: [b']Gimli is *$%@ING HARD ON BRAKES! Or maybe it's my car... I basically killed a set of Hawk HT-10 race pads in 50 laps. The rears are fine - maybe 25% worn, which is what I expected - but the front inside pads are 80% gone! Granted, I was doing between 8 and 12 laps at a time, but they never faded so I figured they were fine. Maybe it's time to get creative with some stock-legal/removable brake ducts... I can't afford to spend $150 on pads for every lapping day. :eek:

I have no idea. I couldn't get the iPhone's accelerometer calibrated so the data you're seeing is inferred from the GPS locations, and it's kinda screwy because the satellite coverage out there is weak. Best I can tell, I'm cornering between 1.0 and 1.1G, braking around 1.3-1.7, and accelerating somewhere around 0.20 - 0.25G.

AutoX cornering speeds aren't any different than the Gimli track, but the entry speeds sure are, as well as the time spent in each corner! Plus there are no rushed transitions at GMP, other than the 6/7/8 complex. I find it's much easier to plan a line and make minor corrections, as you get so much practice in a day. It's an interesting change between the two. Passing skills are completely missing from autoX though, that's the biggest draw to wheel-to-wheel road/ice racing for me.

Interesting... I had a similar experience with the STI, though with fewer laps and less wear. The Subaru forum guys thought I was crazy to fade the pads I had with street tires. I thought I was crazy too! I've only done 30-ish laps with some fancy race pads and a 3" brake duct kit, so I don't know how much I've improved things. Zero fade over those laps, with more power than the previous sessions.I think temporary ducts will be hard to do on the S2000 due to the pretty solid wall that the fender liners make with the fender well. Maybe a 1.5" or 2" duct going under the subframe? Some guys run little air deflector thingies on their lower control arms that tend to scoop some underbody air and deflect it towards the rotors. This obviously won't be as useful as a full duct kit, but every bit helps. Mark's Boxster had these in plastic - quite impressive from an OE standpoint!

I tend to agree except that AX'ing doesn't prepare you for the higher speeds and heavier braking. My spin going into turn 1 is clearly an indication that as speed increases, so too must your reflexes. I'm not a great AX'er yet, but I'd say mostly competent, yet I felt very nervous around Gimli especially into 1. I think the penalty for going off track is higher and, until I can grow a pair, that will be a constant mental barrier that I have to try to overcome.

Yes. Not only passing, but just being on the track at the same time and trying to catch up to or drive away from another car.

Supposed to last a lot longer for slightly more money.

I had a ball this weekend and really found that auto-x prepared me well as I had already felt out the limits of my car! Great instructors and finally got a new addiction to going fast!I'll look forward to more hotlapping and setting up that gps thingie that Beau showed me :P

I felt little to no fade with my bad boys, even when Spence was going at it in the hotlaps, and padwear was normal as expected with wilwood pads! STR friendly! :Dhttp://www.s2ki.com/s2000/topic/940190-wilwood-str-legal-brake-kit/

Your car has factory brake ducts, so it may not be nearly as bad as you think. I understand pad heat and pad wear are highly correlated in most cases.

I ran HP+ and the pads held up fine but I cracked a set of rotors after about 3 events (probably 140ish laps in total). They get so hot they develop little spider web cracking in them and need to be replaced. Maybe cryo would help.The vette is going to hit pretty high speeds so it will definitely be hard on the brakes. Fortunately (relatively speaking) the rotors are fairly cheap.Gimli is very brake intensive. Brakes ares are going to be a wear item for anyone that does lapping. Remember that most pads that live under abuse are generally harder on the rotors. I would rather go through pads than rotors!

One corner I noticed that my AX skills helped with was turn 8? I believe. (the new corner right before the long straight) That seemed a lot like an AX turn so I didn't have as much trouble with it as the instructors made it seem like I would. As far as brakes go my Mazda held up pretty good. Got very little brake fade and the pads didn't seem to wear too much even tho the car is kinda heavy.

So everybody wants a Miata eh?Back to the OP topic, yes I have a few videos (actually a lot). However I'm traveling this week and I don't have access to any video editing software. So you'll all have to wait. I will need to go through it all and figure out what's worth posting.I have 3 videos from hot lapping on Friday, 27 videos (wow!) from Saturday's school, and 6 videos from Sunday's school. Saturday was a lot of short exercises so most of them won't be worth posting but there may be one or two. Of the actual lapping sessions I'll try to find a few laps that are worthy and throw them up on YouTube.

Ummm...quarters...can we afford to supercharge it now :D

Putting a supercharger on a cheap Miata will easily triple the cost if you actually want it to run long enough for four people to get track time in a day. Same goes for adding 50% more power to any car. They're pretty fun in stock form, though the straights feel really long... See Monsieur Marcoux for advice on how to lap Gimli on a budget. His Civic ice racer is probably 15-20% the cost of my STI and 90% as much fun.

I left the engine stock on the RacEscort, for reliability. I can run all day on the Hawk HP pads with no fade and little wear. It eats right front tires however.:( While the slicks are incredibly fun to play on, the track chews them up pretty fast, so they aren't very practical when there's no real competition to justify the cost. I'm looking for something cheap and durable to use at Gimli. Less grip doesn't mean it's less fun. You don't cringe when you kill a set of Costco tires!:)
