      Oh man I am curious to see this video footage. Can you add some telltales around your hood exit too?? Do you have open brake ducts?

        I do! It is in the track forum. I’m on my mobile so I can post it here later.

        I’ve found that I get slightly better cooling if I cover the cabin air inlet and the gap between the hood and windshield.

        The gurneys in front if the hood vents makes a BIG difference. Not sure what the right size is. In the video I took I had a 1.5” gurney and you saw a long tail of recirculation which might indicate air extraction from what I’ve been told. Could be wrong about it.

        Its been experiments so far. I’ll get a baseline in the summer and decide what to do after that.

          I’ve been planning a big cooling and aero related modification for awhile now. Before I did anything, I want to get some reference data to know whether I've achieved my objective of reducing drag, improving cooling and saving a couple of lbs. The plan is to use a non-M manual radiator and a large oil cooler mounted on the back

            Wow no kidding, that floppy hood is really letting a shitload of air pressure under the hood. Definitely seal that up! Also, did you delete the radiator shroud/guide in front of the radiator? It looks like your telltales are showing the air being directed around the radiator. I would have expected the nostril telltales to be way more straight lined into the radiator with ducting and hood vents. Very cool, thank you for sharing

              I still have the front ducting. I need OE kidney grilles so the air doesnt spill between the hood and the ducting.

                Onto NASA Houston Spring Fling! Only my 2nd event and a lot of learning.

                TT4 only had 1 entrant so I ended up running TT3. Not really ready for TT3 but these Falken RT660s will carry me to victory! I am going against a fast driver in a fast car (E92 M3) - I'm pretty sure I was his last instructor 6 years ago. I know for a fact he's a fast driver so it should be a good challenge.

                I had to be at my best to have a chance and I wasn't. When I analyze data, I usually want to see a couple of things:

                - 2 best sectors in the best lap
                - a best rolling lap which includes 2 or more best sectors in a lap
                - sectors should generally be within .1-.3 seconds of each other

                If I meet those 3 criteria, I'm driving well and consistently. And this data is useful to figure out where I can find lap time.

                Despite my weight being optimized within 10lbs of my min weight...I never got there. Got smoked by 3 seconds.

                - Falken RT660s won't cut it in TT3...not even close. At least for this platform.
                - Ballast can be used to tune the handling. It might be possible to improve or even optimize L-F and F-R balance with careful ballast placement. The biggest limitation is mounting location.
                - Excuse here...the TC Klines are about dead. I think the right front strut didn't like going off and catching air back in Jan. The splitter scrapes a more often on left handers and it feels bouncy.

                I could have been about 1-1.5 seconds closer but I don't think I could have beaten him. I did outrun a C7 vette and a CTS-V on slicks.

                  Falken RT660 review

                  These are great budget tires that I think are faster than Toyo RRs. 275/40R17 set me back $1026 plus tax.

                  First, definitely takes an extra lap to get them to temp. My hot target for RRs is 30psi which puts me at about 22-23psi cold. I bumped these up to 24psi which got me to about 31psi. I will try higher pressures to see at what point it gets worse. I think I'll settle around 32psi.

                  First, they are the opposite of the RRs - stronger front end with a weaker rear. Once they were up to temp, the front end had more bite and feel especially under braking. Braking is the RR's biggest weakness. The rear end felt vague with the Falkens. It was more difficult to throttle steer. Maybe slightly higher pressures in the rear could help with this. I'm guessing there is a difference in sidewall stiffness.

                  I have 12 heat cycles on them so far and the wear looks minimal.

                  So far these are relatively faster 200 treadwear tires for a budget and seem to last. Looking like a great DE tire.

                    Blake is very fast, tough competition for sure. Don't sell yourself short either, you forgot to mention that to beat him you would have also had to set a TT3 lap record. And is he still running 315s? I thought I saw him mention trying to fit 335s?

                      Not sure what size, he mentioned he was running Hankook slicks. Yeah, Blake is an example of a great driver with a well setup car. I beat him last year at MSRH but I don't think he really came fully prepared. I did walk away learning a lot more this year than last year.

                        Trimmed and ready! Didn't bother with the polish on this one.

                          It has been a race against the weather. Need to get the dash mold done before it gets into the 90s. Fiberglass work is really not possible...or at least quality work is not possible. Got it done, came out great! Only 2 minor repair areas and the OE dash did release from the mold.

                          Prepping the dash to pull a mold from took awhile. I finished this back in Feb but got sidetracked.

                          I had to do a split mold. The mold is two parts that line up to make one part. This aids in getting parts out of the mold.

                          Still have a little clean up and some repairs to do but it came out really good!

                          The dash was delayed due to making a new hood mold. 3rd time is a charm...first part came out great!

                          Lesson learned, really need a partial underside to keep the hood from flapping around. About to bond and then final trim.

                            Bought an AiM ACC2 to get brake pressure data.

                            I am using this guide to tap into the existing brake pressure sensor wiring

                            MK60 Brake Pressure Sensor Data – GSR Motorsports

                            I had to pull out the ECU and box to get to the wire. You have to dig down in there because the sensor wires head down towards the ABS unit, not towards the ECU. Tapped into the black/violet wire.

                            The I bought a 4m 719 patch cable from Pegasus. The blue wire was pin 1. Not sure if this is the same for all of the Pegasus' patch cables. Routed it to the center console area through the firewall. Would have been fine with 3m.

                            Bad news...I have an old AiM Solo DL. A new sensor has to be programmed in Race Studio 3 so I need an Aim Solo 2 DL. I am debating on whether to go with an AiM dash or a Solo 2 DL. More of a reminder for me, the AiM dash was attractive because it would allow the addition of the brake pressure data. I can do that with the Solo 2 DL...so I should go that route.

                            I've made a commitment to keep my hobbies revenue neutral. I have to make money to spend money on my hobbies - cars and ice hockey. So the Solo 2 DL will have to wait until the summer. Just bought tires and lots of carbon fiber stuff.

                            Tried to get some aero data from around the wheels. Didn't work out because my hood is too flimsy. I could have tried to mount the gopro on the windshield. It was last minute and I was too lazy. Maybe next time.

                              Finding out the E46 poses a lot of challenges with splitter tunnels. The tunnels go right where the most common mounting location is under the frame rail. Then I lose a lot of area under the engine.

                              I can make a bracket to go over the tunnel for mounting. I will develop a brake cooling deflector plate to work with the tunnels. Last piece of under car aero is making a flat bottom thrust plate.

                              Doing my first cast molds. If this works, it will enable me to make small carbon parts relatively fast. I can make the mold in a couple of hours and then cast a carbon part in a out an hour or two. No hunting down vacuum leaks, and closely watching infusions although it is oddly exciting.

                              Floor mount adaptors and Heinzenboehmer’s strut brace mount.
