Second outing for the Alfa on RE-71Rs.  CCW this time:

 

Track:  MSR-C 1.7CCW
Date:  5/29/2017
Lap Time:  1:25.194 (Track Addict + XGPS150A 5Hz)
Car:  '15 Alfa-Romeo 4C
Estimated Weight w/Driver:  2750
Estimated WHP:  ~210 (Stock)
Tires:  RE-71R
Suspension:  Stock
Weather:  90F+, Sunny, 10mph North Wind

 



Here's an interesting comparison between my Miata and the 4C, driven about 1 hour apart. Same laptime accomplished quite differently.

4C is an impressive track car. Even more impressive is how it handles the early Summer TX heat. My friend's 2017 Z06 was puking out on track (who knew an electric steering rack had a "limp" mode?!?). The 4C -- water 195, oil 205, all day long on back-to-back 30 minute sessions. It's so good, I almost wonder if those gauges are placebos, but they do reflect the car warming up, so?

overheating & limp mode is a disappointingly common occurrence with the Z06.  

It doesn't happen to all of them on the track but more than enough to be a problem imo.  

 

On another note I think may look into incorporating a youtube double like function on my site to compare two laps I like that idea.

YouTube Doubler is pretty cool.  Synchronized start is kind of hit or miss though.  I often have to hit "replay" several times to get the videos synched up.  They should improve that.  If you do a similar tool, that's a really important part for comparing laps.

Yeah, that's the tough part. From the browser's point of view, it is two links, to objects to load... not sure there's a good way to synchronize the start of those videos with YouTube.

Well with YouTube you can share a video and have the link start at wherever you want it to start, is if you know at what second the lap starts you can justbuses the start time embedded link

I did some testing with my own implementation last night and it seems to be more consistent if you use the start time embedded links.

Still too buggy to put on my site though

Track: MotorSport Ranch (Cresson) 1.7 CCW
Date: July 29, 2017
Lap Time: 1:20.577 Aim Solo
Car: 2013 Scion FR-S

Weight with driver: 3005
WHP: 204.3

Tires:Hoosier R7s 225/40/17 on the 6th heat cycle 

Suspension: JRZ RS Pros, SPL everything

Weather: 87Fs, partly cloudy

 

Sorry the audio quality isn't great. Apparently my microphone is failing.

 

Incredibly happy with the first day of testing the new suspension and the times, especially considering the heat! The predictive best for the day is a 1:19.353, so still lots of room for improvement. 

 

The guys at Inertia Labs have been awesome to work with on the new suspension. They valved everything and chose the springs according to my corner weights and expected aero load and then came trackside to help dial it in.

I would guess Element Tuning or Evasive Motorsport have the fastest 86 here, although I think they have all swapped motors. There are some really quick guys in California with N/A 86s, it would be fun to see how we compare.

That's really hauling, awesome job. Flat through ricochet and the complex, that aero seems to be doing some work.

 

When are you going to do some TT in this thing?

 

PS: are those the tires you got from me a while back?

I am hoping to do a NASA event or two this year with it, baby coming anytime so that is making scheduling a little tough. They aren't the tires I got from you, I will try those next! I bought these as takeoffs from GSpeed and already had a set of wheels there, so had them throw these on.

What class are you looking to run? I feel like even with the hoosiers and aero, with 200WHP you'll be pretty competitive.

TT4. I am a bit underpowered/overweight, but I am hopeful I can be competitive and can continue developing the car. I may look at the TT5 rules once those come out to see if it is possible to fit in there (that is probably the better class).

Track: MotorSport Ranch (Cresson) 1.7 CCW
Date: March 12, 2017
Lap Time: 1:23.789 AMB loop, NASA TT weekend (new TTD record by 3.8 sec)
Car: 2001 BMW E46 330, TTD class, still daily driveable

Weight with driver: 3285 lbs
WHP: 219.3 SAE

Tires: Hoosier R7, 245/40/17, on 17x10" Forgestar F14

Suspension: MCS TT2, Whiteline bars, Powerflex bushings, Vorshlag top mounts

Brakes: Powerbrake 4 piston BBK with PB23 pads up front, G-LOC XP20 rear pads

Weather: 44°F, cloudy

 

 

Remote microphone fell down into passenger foot well after lap 1, so audio is a bit washed out. Car is still way down on power from the TTD class max, but with a stock 164K mile 3.0L M54 and a header it did all right. Tires were getting "tired" but could hold 1.2 g and spike past 1.3. No aero, no LSD, but the brakes worked great. Driver is a hack autocrosser.
