lol i lived in SFL for a while, my brother in law bought a house built in 2005 in 2010 for less than half what it cost in 2005. I'm sure it's back up to 2005 level now, but it'll drop back down here before too long, just how it goes down there.

Back on topic...

Travis, post pictures of your car for Christ's sake!

You guys probably saw these pics of the new C7.R prototype... the rear diffuser is interesting and I may try to replicate. Looks like six attach points and should form a nice 7-9 degree angle from the rear axle / underbody tray. Wonder if they allow any air to get in above it - other than the air coming off rear wheel wells?

Definitely an interesting design. Looks like they are letting air get in, but it might go through some heat exchangers first or something.

could be. although the c6 had the heat exchangers exit through license plate area, and i can see that there are two such vent openings in that area on this car... so guessing it is just open area. would appreciate if anyone can find / pls post here any more detailed pics.

it may also be they have some air flowing over cooling fins on the rear diff casing and whatever else.

as a side note, at least for this prototype, from the looks of it they are using the same 3/8 plastic 'boat board' that I've been using for my front splitter... it's heavy for a car like this, but maybe fine for them given they prob have a min weight to meet

looks great!!:tup:

Final prep at CIN

Love the rear cutouts

love the entire car lool!!! looks great my friend!!

Uhh any more detailed information and photos of what all has been done to this car???

makes me want to see more of this car :tup:

Thanks guys - as I said before CIN is a great shop and recommend them to anyone in the Carolinas...

Anyone going to CHIN Road Atlanta or next NASA VIR can see it in person... otherwise can read through these 124 pages for the details... I may come in here and do an updated spec sheet and video walkthrough at some point but that's not high on my list right now sorry

Next weekend. I'll come up there. You don't have a passenger seat do you?

Pot= kettle....you know the rest

Travis, is all awesomeness

sounds good! unfortunately not on the seat... maybe get a ride with someone else in the groups and we can lead / follow

thanks man

so my dyno runs came back
Map 1: Max HP 398.29 Max Tq 315.57
Map 2: Max HP 393.47 Max Tq 313.27
Map 3: Max HP 373.53 Max Tq 313.98

My NASA min weight for TT2 with big tires will therefore be 3,191 lbs coming hot off the track (spent fuel with driver and gear)... may have to ballast just a little

Ooh. I would love to drive my 370 at 3055lbs. My 05 (DE) 350Z is 2860 and is so much more fun to drive than the 370 at 3480. Though I think a lot of that is the garbage throttle response in the 370.

I'm not there yet on 3055 but agree this car begs for weight reduction. Any event, I'll be running the bigger tire scenario to get to TT2 and so min weight will be 3191 not 3055. I may have to ballast just a bit now that I have phunk's fuel starve kit and will be able to run 1/4 tank

Are you using single mass flywheel, sig?

Nope. I'm mostly stock... getting the car ready for SpecZ. Expected to have it done by now but my cage builder has been really backed up with Miatas. :P Only clutch/flywheels I can run are the stock or NISMO.

This summer I ran better times in the 350 on street tires than I was running last year in the 370 on Hoosiers! Amazing what 600lbs does. :) My last event of the year I was about 5-6s off of my friends in C6s on conties/hoosiers. Should be right up with them on race tires of my own. I have some fun video once I get some free time to edit it.

Awesome weekend at Road Atlanta. First time there - that track is amazing fun but pretty treacherous. Not the kind of place to learn car control. There were ~90 that started the weekend and three cars left in pieces. Drivers seem to be fine, thankfully. Downhill section leading into turn 10a took one, another over-steered out of turn 5 I was told, and the last I think was near start finish (need to confirm).

My times were 1:40/1:41 all day long. Then I took a ride with a local and found some new lines and break points. Unfortunately only got one clean lap to end my day today with the faster line, but very happy with the time of 1:39.14.

Way home... 70 miles short of home base, nice couple honked at me to let me know that I was missing a wheel. Oops, guess these things weren't made for going 85 through crappy Charlotte roads!

http://i656.photobucket.com/albums/u...ps0c4b48cb.jpg

BTW, figured out you can just strap the hub with missing wheel to the frame and limp home at 47mph... long drive

Great times. What tires where you on? T1 time can always be picked up time wise. Exit of T7 is the tricky one.

NT01 I'm pretty darn close to 100mph at turn 1. I think I have turn 7 down pretty well. Not accelerating enough and carrying enough speed through 10b, 11, and 12... but for good reason as you and anyone that's driven RA would know!

Nice times. I'm at 1:39-1:40 on NT01s

good to know - people at the track were saying slicks are good for 5 seconds... guess that's not how it's worked out for you?

That's not how it works for anybody. Gotta have the right spring rates, sway bars, etc. to go along with the slicks to make them work properly. They obviously have the potential for a lot more grip but they will completely change the dynamics of a car that's set up for a harder tire. I drove a car setup for R-S3 street tires, threw some Hankook DOT slicks on it and only went a couple of tenths quicker. Made the car nearly un-driveable at speed. Springs were way too soft, sway bars were way too soft, we were hitting the bump stops, bump steer was much worse since the car was moving around a lot more, diff wasn't working as well since the sways were too soft, etc.

Possible you were getting used to the slicks and how far you could push them? I'd be curious to see more data.

As I said, just relaying what some people at the Chin Road Atlanta event were saying about their own experiences and observed time differences at RA. My experience running slicks is only at two tracks, PIR and Chuckwalla. They were good for a couple seconds over my Hoosiers R6's at both of those, and the Hoosiers were good for a couple seconds over my NT01s.

Nah, when I went to NT01s from Hoosiers, my friends told me to expect a 2 second loss, which is about right. The 1:36 was on Pirelli full race slick scrubs I got from Brian Kleeman, they were done after a day but had tons of grip! Hoosiers are about 1:38

Sad thing I know a couple guys that have done 1:33 on street tires in a 370Z.

3:33?

1:33 :facepalm:

that's pretty amazing. guess I'm not surprised - nasa tt records:

TT2 180 Daniel Sanzera C6 Corvette 1:32.68 9/15/2013
TT3 71 Mark Nunnally C6 Z06 1:30.65 9/15/2013
TTS 169 Danny Popp C5 Corvette Z06 1:27.29 12/4/2011
TTA 71 Mark Nunnally C5 Corvette Z06 1:31.10 12/4/2011

looks like lots of guys getting down into the low 30s and even high 20s... man, i've got some work to do! i only have about 25-30 laps at the track, so i could see getting back a few more seconds here and there, but not 9! damn.

Turn the boost up. :icon17:

nah, i'm done screwing with that... i may pick up some by continuing to make the airflow more efficient over the intercooler - i think i'm getting some serious heat soak losses. third dyno run was 375whp for example... but otherwise, I think i need more time at RA and maybe experiment with different tires. new set of R6's on the way that are worth a couple seconds, I'm convinced. And if I get my darned SRM back that's gotta be worth a second for me given my otherwise ham-fisted approach to shifting / heel-toe

I've got probably 1000 laps there, at a minimum!

you're a lucky man to have RA as home track... guess I can't complain with VIR in backyard either!

while i've got the attention of some ra experts, let's talk gears by turn number

turn 1. downshift at end of straight under light braking from 5th to 4th then turn in with slight trail braking (i think this would be better with mid turn downshift with SRM on)... concrete patch in mid of left front wheel and stay just off curbing with right wheel

3/4. hug curbing maybe 2 feet off remaining in 4th gear all the way through these and then all the way through esses

5. setting up entry with straight line coming out of right hand ess, then downshift to 3rd under braking and accelerate rolling out to straddle curbing

en route... shift from 3 to 4, then 4 to 5 (for me this is a must about 1/2 way to turn 6)

6. light braking with downshift to 4th... would be better with srm or perfect heel-toe, as right braking zone appears to be after initiating turn

7. make a straight line on bank of turn 6 towards 7 turn in point, brake hard, down shift to 3rd while braking hard, hard turn into to apex (I over turn steering input to get the understeer started) then let the front wheels catch into straight line and get on it as car settles just before apex

long straight, i end up in 6th gear just before downhill if I came out of turn 7 as planned

10a. downshift to 3rd in the heavy braking zone, hard left turn with slightly late turn in to get somewhat on the left side of 10b turn in and get max speed coming out of 10b

10b... exiting 10b, shift into 4th hopefully before crest of hill... when I time this poorly I was hitting a divot on top of hill (driver under red mark in sign) and getting a little squirrely... usually shifting 20 feet before crest

11/12. straighten out at bottom of hill and shift to 5th before start/finish, hopefully not unsettling the car! I'm being a big puss in turn 12 and holding 3/4 throttle so my eventual shift point is probably sooner

Random question, Travis: I know you do without SRM. Would you rather have it back?

Sent from my Galaxy S3

I'd like to have the option... at RA for example, new track to me and rather dangerous... SRM just takes one element of danger out of the equation... and as I get comfortable with a track I can take it off and practice heel-toe

Side note... Probably a controversial thing to say but I think 10 years from now only vintage racers are going to have manual trans.

btw, i had to catch 2 or 3 botched heel-toes at RA this weekend. I recall 10a downshift to 3rd getting ugly a couple times. not really a big deal at that particular corner, just had to snap the steering wheel as the rear stepped out. also once on braking zone before turn 5... but if it had happened on turn 1 for example where I use every last bit of tarmac on the roll-out, would have been a big big problem as the correction would have taken the last 6 inches I kept in reserve

Must be the different levels of power that put you in the higher revs quicker being your FI. So I'm speaking from a NA mind set. T5 I always down shifted to 3rd also (I think Mike doesn't, sometimes) to pull you up and over the crest faster (especially to pass) and then shift to 4th. But never got to the point of shifting to 5th (again NA mind set), never got that high in the revs.

Back straight before T10a. Again must be the power difference, I top out 5th well before the dog leg there but never could reach 6th gear. I brake late on the descend before T10a hitting nearly 140-145mph. I'll continue later. Have to go to work.

After 10b I used to short shift to 4th before the bridge/ crest. Not sure about a dip. But now I shift after the bridge as I'm starting down the roll out far left. I felt I was losing way to much momentum by short shifting.

And as far as T12 and 3/4 throttle. Me to. Me to. Butt loads of momentum in that descend. Always treat with Hugh amount of respect. I've heard the big dogs talk about going full throttle threw there and it will hold if entering a late apex. But I'll save that for for later years.
