1st ever Sprint Race - 6-9-12 @ Gingerman!

After arriving about 10pm and drinking until 2:30am - morning came quick and I made the registration switch from PTA over to ST2 already.  I knew I didn't have a chance in ST2 w/o at least good tires but I wanted to be in the faster rungroup and get used to the traffic.  My goal was simply get the car through the weekend successfully and see how everything felt and reacted over the course of an entire race.  I prepped the car and went out for practice on street tires to feel out the brake updates.  Everything felt solid, although the car pushed hard on the street tires - which it has all year since the cage went in - I ran a 1:47 and had a car spin in front of me and 2 of us had to split to miss it in the track which was fun.  I was weighed afterwards and started doing to the math for the ballast I'd need.

I switched rims to the last of my leftover 2011 255 Hoosiers and stuffed the car full of fuel until it ran back out!  I only ran a few laps and qualified with a 1:41 trying to save the tires as they were pretty beat up from running hard TT sessions last year.  Last year pushing hard on the tire setup I ran a 1:38.8 (current TTA record) so I was in the ballpark.  I made weight, but not by much, so we definitely would need to add ballast.  Another issue was the oil temps.  In my effort to fix the brake cooling issue I admittedly borrowed from the oil cooler flow as well as fixing the hole in the rubbed fenderwell by adding a chunk of plastic.  I think the latter made things worse so I removed it and then worked up a special duct from the 'faux hole' around to the oil cooler.  I was fairly confident this would make things at least manageable. 

With a 3hr gap before the race I had some prep time.  I had a tire that was starting to cord, so I replaced it with an another used 255 I had.  I also was able to secure the ballast I needed, with the help of Jason from GP Racing we secured 25 lbs in the passenger side and another 30 lbs in the trunk.  I'd already topped off every fluid container in the car (oil, radiator, drink bottle, windshield fluid, fuel, etc).  Not knowing how much fuel the car would burn I errored on the heavy side as I didn't want a DQ.

The race went pretty well overall.  All of the ST cars lined up in the 1st of 3 waves; I was 9th of 12 in that group and started on the inside of a very tight T1.  I got a good jump, but all the big V8 N/A cars in front of me pulled harded off the line.  I also realized from my vid I should have been up closer to the car in front; so I'll learn.  I took T1 pretty slow trying to stay clean and dropped below boost in 3rd so I lost some momentum there.  I ran a few 1:42's and after that settled into a pace around 1:45-46 carefully eyeballing my oil temps the entire time around the 280-285 range.  I babied the car, avoiding the high rpms when I could by shifting early and pushing the clutch in to coast into braking zones - all tricks that I know help the oil temps.  Brakes felt good throughout and the tires stayed underneath fairly well since I wasn't pushing hard.  I picked up a few overall spots from traffic and I picked up the pace on the final few laps just to see how the car felt and the tires were giving up for sure.  In all the race lasted 17 laps and I covered about 43 miles.  As for the fuel, after the race I had exactly 1/2 tank but was not weighed.

Putnam Park - 5.13.2012 - Drifting into 1st place!

Saturday evening I rotated the tires; X'ing the front backwards. I figured the LF would be nearly bald - and it was. But the RF was worse! Sunday was going to be interesting with no grip in the rear, but I was thinking since the fronts looked ok that I'd at least be able to turn like I could early Sat.

(Pic):  Left side tires from Sat evening. Front on the left; rear on the right. I rotating the bald ones to the rear....

I made more suspension tweaks, rolling back the changes I made late Sat in hopes it would help the car grip more. I had some pulsing in the front end under braking on the out lap. I figured something was stuck to the rotor and/or the tires were flatspotted from sitting all night as I had reset my pressures to my normal morning starting pressures. It seemed to go away with some really hard jabs so I put it out of my mind and hit it hard. I ran 6 laps with a best of 1:18.2 which the car was no longer sliding, but rather drifting today! Jeff's Evo was behind me this session and got some good vid; check it out below.

For S2 I bettered my time to a 1:18.1 but that's all I could get. The rear was drifting around so much that I had to do more than countersteer, I had to get out of the gas some which is a killer for times. This is the session I put the camera on the rear and had a Mustang 302 behind me. My overall times were better than his, but in this session I just couldn't get the power down and after drifting through T4 and getting out of the gas I simply pointed him around.
When done, I looked over my tires carefully to see how bald the rears were now and to verify nothing was corded. The tires passed inspection, but the LF rotor did not. Check it out:

While I had a spare, it was 12:30pm at this point and very hot. With basically 0 chance to improve my times and only to play around more, I decided to forgo the fix and just pack things in and go surprise visit my Mom with it being Mother's day and all. It'd only add about 45min to my overall trip. With all the crazy turmoil with my wife's family recently; I've been trying to take the extra effort with regards to visits and calls and whatnot. I was actually going to cancel this event but the wife told me to go and enjoy the distractions. So I watched the start of my friend's race after packing up and took off.

Overall the car did great. No mechanical issues, just the broken exhaust bracket which was no biggie, the broken rotor which is a wear item and my boost gauge is still broke (so no, I've no idea what boost I was running). Oh, and my time easily held up Sunday for first in TTA once again.

After looking deeper at all my GPS data, everything is pretty cut and dry.  An 8/10's lap from 2011 on wider A6's yielded a nearly identical laptime to this year's lap at nearly 10/10's on skinnier R6's. Nuff said.
Braking force with R6's is crap compared to an A6; I had data confirming this already. Cornering G's were about the same but that's the 8/10's vs the 10/10's thing to allow that. I was able to push my brakezones a bit which is good and the car rotated great w/o hardly any understeer given what front grip I had at least.

The 2012 setup vs the 2011 setup to me feels better with regards to power and rotation. I'm really happy with how smooth the car idles, and I don't even notice the Synapse BOV thx to Buschur's tune (he assured me it'd be smooth; he's right). The differences being a Buschur tune on the engine this year and an ACD-tuning update in the ACD unit. Also different on this track were taller tires and a taller 4th gear as compared to May/2011 - both of which hurt my laptimes as the car was previously geared incredibly well for Putnam. With less speed on corner entry from the ****tier tires and the gearing changes I was actually forced to downshift twice more per lap to keep the turbo spinning. So factor in all those changes and running 1.3 seconds behind my blitzing 2011 time of 1:15.7 and I'm feeling pretty good about the car.

Video's coming...

Putnam Park - 1st in TTA - 5-12-2012

After running the Enduro on Friday afternoon/evening, I awoke at 6:45am Saturday tired and sore.  I still had to unload, unpack the car, and do some prep but that was about it.  Our warmup wasn't until after 10am so it was relaxed.  For the warmup I lined up around grip spot #3 I think and after waiting 1 lap for things to come up to temp I put down an easy 1:17.9 to earn #2 in grid.  I then went to tech and got weighed since I still had no solid idea of what the car weighed post-cage.  It came in at 3198 lbs; which was about 50 lbs over what I was claiming for the day so I was pretty happy with that given the current fuel load. 

Session 2 was at noon and I made no changes and fired a 1:17.0 which slotted me first in class and first overall.  I hit traffic very quickly as there were 44 cars in TT on Putnam's 1.7 mile course.  Also someone nailed the hay bails in the final turn so we had a few sitting on the exit of T10 which was right in the line - and after 2 laps of that I seen the double yellow.  I was probably going 130mph when I seen it, closing in on 2 lower classed cars probably going 95-100mph but I made the passes safely before the flagstand and tucked in behind the traffic.  Oddly though that traffic was another car giving pointby's that was off pace.  By the time I realized it I'd been re-passed by a few cars - I think this confused some cars as other passing from other cars ensued and only 1 was called in for passing under double-yellow.

For S3 I made a few small tweaks and ran a best of 1:17.2 but the car was really starting to slide at this point.  Wasn't sure if it was the heat - sunny and around 85 - or the tires giving up.  I figured a bit of both.  I know I was starting to drop 1-2 tires into the dirt in multiple corners on exit as the car just wouldn't hold and would slide.  It made 'catching' the slides a bit interesting and fun but I knew this wasn't going to be faster.  I was also given the pleasure of the 'meatball' flag and when I came in was told my exhaust was rubbing and throwing sparks.  This shocked me as there was no audible difference.  When I got back to my paddock spot I seen the brace by the rear axle had broken and it was hanging low and would need a bandaid!  I recently had another bracket re-welded and perhaps with that being tighter, me dropping tires and that rear brace being rewelded back in 2009 - the extra pressure caused it to break again.  Either way I had 2 hours to fix it, and with my idea and some help from a friend it was pretty simple.  (see pic)

For S4 I adjusted the suspension a touch to try and aid rotation/grip assuming things would be worse if the tires were the problem.  I had my answer in the first lap; it was the tires!  I ran 3 hard laps right around 1:18.3 until I hit traffic, then I played for another 1-2 and drifted.  I actually had a few people ask who left the drift marks in certain turns as I was at least having fun!  At this point I new the tires were shot, having 12-16 Heatcycles each.  Also good news was that our exhaust fixed had held up just fine.  My time from S2 would hold to land me 1st place in TTA by about 3 seconds - but I was 1.3 seconds off my record from 2011 when I was on wider stickier rubber.  But considering the tires I came with I thought the car did very well - running times right where I thought we would.  Power was smooth and rotation was great with no understeer; just an overall lack of grip especially at turn-in from the worn tires. 
Vid from Sat; A lap each from Sessions 2 & 3 from different angles:

Road Atlanta - 3.10.12 - Day #1

 The day started with a 7am meeting. The TT group was first out at 8am. I went out on street tires with a goal to learn the track, stay out of the way of the locals, and try to set a fast enough time to stay towards the front of the grid.
The track was... pretty fun. Nothing too crazy. I was motoring down the backstraight and glanced down to see the odo approaching 140 really quick. Damn! Got past that; through the 'S' curve and then I went under the bridge and down the hill into T12. Holy sh1t; it was like the Log Ride - seemed like it was straight down. This was going to take some getting used to...

For S2 - I went back out on the street tires again. I was picking up the track, but definitely coasting down the latter part of the backstraight and down 12 (the huge hill) I netted a 1:39 still on street tires! I was actually pretty proud of that.

For S3 - I bolted on the Hoosier R6's. 2 were new; the other 2 were used so I'd need to scrub everything in. I tried to keep my track positioning in the first 2 laps and control the inevitable skids - which was fun. After a 1:37 I reset my tire pressures and was ready for S4 to hammer it.

S4 - Traffic! By now I was working my way through some of the TTS cars that are 1 class above me and run more HP. I'd catch them in the first part of the track but they could pull away down the long backstraight and down the big hill in T12. Track positioning is definitely important for a flying lap in TT. Best of 1:36.5.

S5 - I was up to 7th on grid by now, but as not everyone went out I was actually 3rd. This proved to be my best track position and allowed me to hammer w/o having to worry about navigating any traffic in front or behind. I had my best laps of the day; with the overall best of 1:34.8 that netted my 1st place out of 3 in my class of TTA and 5th out of 38 overall in TT.

The day turned out great, the Evo made it through it's first track event of 2012 with flying colors, which included a new tune by Buschur Racing. No problems over the ~100 miles on track including a top speed of 149.87 mph on the backstraight and around 130 on the front!
So I quickly rotated the tires and checked the car over before Then off to the NASA awards ceremony just off the main straight.  Above is a good vid from Session #2 looking backwards to demonstrate some of the elevation changes at this track.  Enjoy!

 

2012 - Parts on Order!

While the car is currently sitting at Buschur racing, I've been busy gathering parts needed for 2012.  Some the Evo has been waiting on for install and re-tuning, some are needed for maintenance before the first event and others will be needed down the road in 2012.  Here a quick list of what's either been delivered or ordered in the past few weeks:

• Updated ACD - ACD Tuning!
• Hawk Front Brake Pads
• PowerSlot front rotors - slotted & directionally veined
• Flat aluminum piece (reinforcement for splitter update)
• 3M Epoxy (for splitter update)
• Buschur Racing Oil Pan (improve oil pressure under G loads)
• Buschur Racing O2 Housing (more powa)
• Synapsis BOV (better hold high boost)
• Set of Hoosier WETS (road/race tires for use during rain days)
• Ice Vest (hoping to keep cool this summer)

New Front Rotors & Pads!

I thought my rotors might last through Nationals; nope!  This pic is of the LF and yep that's a nice looking crack.
The RF actually does not look too bad.  Obviously I'm pulling these off in favor of a new set and putting in new pads as well.

More of the same; Stoptech front slotted and directionally veined rotors with Hawk DTC60 pads all coming from Jay at Andrews Racing.  Check out his new website and don't hesitate to hit him up for advice on your setup: http://andrew-racing.com/

2010 prep/maintenance - Rear Brakes, seals, dust boots, fluid & rotors

Through this year, the Evo has about 45 track days and 22,000 miles on it.  All of that is with the stock rear calipers, seals, dust boots & rotors!  As the car uses the front to brake in about a 3-1 pad usage ratio I have been through the front setup many times and finally decided it was time to replace the internals in the rear.  I also took the opportunity to put my Hawk DTC60 track pads back in and do a full fluid flush with AMSOIL DOT4.
Here's a few pics of the fun in progress and a shot of the finished project.

Wow, the joys of car maintenance!

Check out the calipers -->
The top is a nearly new stock red Brembo caliper. The lower is my RF caliper which has been discolored from high braking temps on the track! A true badge of honor!

Last night I switched in new front Hawk pads, new front rotors, switched in 1 new front caliper, switched out the tires and bled all the brakes with AMSOIL DOT4. Whew....

Fresh set of rubber arrives - Hoosier A6's

Fresh new set of Hoosier A6's just arrived. Really interested to try them out as compared to the R6's I have been running.

Last week I received a new set of Hawk brake pads for the rear; backups!

I am still awaiting a set of front rotors en route from KNSbrakes.com and we'll be all stocked up with backups!

NASA Midwest - Putnam Park May 16-17

#2 event for the NASA Midwest chapter, #1 for me. This was actually a crossover with the larger 'Great Lakes' region as well so a ton of cars. TT had nearly 40 for the 1.8 mile track!My previous best from a last month there was a 1:22.5
Changes included new AMSoil 10w40, a heatwrapped downpipe, a new Sparco seat and running 245/40-17 Hoosier R6's.
Saturday: Some light mist in S1/S2, S3 totally wet (everyone skipped), and S4 the best. Around 65 most of the day. Ended up with a 1:22.2 and placed 2/6. Contingency $$ from Hoosier and Hawk! I missed first by about 1 second to a much higher hp car.
Sunday: Good weather all day. Improved to a 1:21.5 Ended up 3/6.

Overall, the car felt good, a little down on power in the straights and needs a longer 4th gear for the track for sure. I don't think the gearing is well suited for this track, but that's how it goes sometimes. I've got a few ideas for small tweaks before the next event to help things out!
