#112519 1999 Lexus SC400 - I messed up good this time

Posted by Matt93SE on 15 February 2019 - 10:55 AM

Harness looks good, other than the heavy use of white and green wires with no labels.  as a EE and currently dealing with a large telecom system installed by idiots, unidentifiable wires are the bane of my existence right now.

at least you can easily see both ends of those wires and *shouldn't* have to cut into anything or trace wires assuming the terminations are correct and it's truly plug & play...   


My dad bought a replacement engine harness for his 240SX, and every one of the important connectors was miswired from the place that made it.   it cost him 3 engines, 2 "shops", and a couple thousand in diagnostics at a good shop before he finally got everything sorted out.  I sincerely hope Panic's quality is vastly superior to Chase Bays!

#112153 NASA TMS Roval?

Posted by Matt93SE on 31 January 2019 - 12:55 PM

If it's the same configuration as when I ran it in SCCA, I wasn't terribly impressed.  one LOOONG straight with a fast kink, 4 u-turns, and a flat out chicane.  It was all about the HP, but handling still meant something.


they teamed STU with Spec Miata that year, and I was having a problem with my rear brakes (way too much of them!), so I couldn't brake hard into turn 1 without going backwards.  the fast STU cars were several seconds ahead of me, so I was out by myself right about the same lap times as the SM leaders..


I would come off the front straight WOT at redline in 5th gear and drop down to the apron around NASCAR 1-2, then go back high and gently slow so I wouldn't spin.  Jim Drago, Michael Ross, and one of the other East Street Miatas were right behind me pushing each other for the lead of SM race..  they would dive under me when I went high at T1 and get a few feet in front through the infield bit, then as soon as we'd get back on NASCAR T4, I'd bump the 3rd and 2nd place cars in front of Drago and then drive around all 3 about start finish.    I'd pull 100ft or so on them by the end of the straight, and then repeat the process.   Every time I'd drive by Drago, I could see his face turning more red by the lap. :)


With about 3 laps to go, I quit doing that and just stayed behind them all so they had to fight for their own win.


Anyway, the track layout itself isn't the greatest (just about every other track around here is more fun from a technical perspective) but you do get some massive speed around the oval.   It's also a bit of a mindbender crossing all of the stripes on the track so you definitely have to look around and not just at the stripes...

#112129 ECR improvements - can we get regular updates in here?

Posted by Matt93SE on 30 January 2019 - 03:07 PM

Has a birds eye map of the final layout been shared yet?

There's a sketch on page 1 of this thread if you've forgotten.   Not sure if that's where they still are on configuration, but it looked promisingly fun. :)

How long before he gets his first Camaro?

Nothing worse, I am sorry :(

Well at least she still calls Miatas sissy cars..

#111659 1966 Datsun Roadster Build Thread (Street Car)

Posted by Matt93SE on 07 January 2019 - 11:29 AM

I hear you.   I got really burned out constantly working on stuff and throwing money at my race car just to keep it on track and not actually going any faster.  for the money I was spending, the car should be several seconds/lap faster than it was.

Started my daughter in karting 2 yrs ago- and my son yesterday-- and I'm having so much fun with them, I don't miss racing much myself.  I get to go and play with them and all of my cars have been sitting ignored for months and I just don't care..

#111446 Tell me what new(ish) DD to buy..

Posted by Matt93SE on 29 December 2018 - 10:39 PM

So I wound up with a 2015 Q50s..  Yeah I broke down and bought an auto...


I drove a few more cars today and my last stop was at the Subaru dealer to re-try a 2018 WRX..   They had a Q50 on the lot for the same price as the WRX, and it's a much more well-featured car.  I decided to go ahead and drive it as well, and the stock S trim handles just as good as my old (slightly modded) G35, plus gobs of power even with the auto.  I threw an offer $2k below their asking price- which was already a fair number- and told 'em "take it or leave it".  I expected to be walking out 5 min later.  They took it- yaay?


I got the paperwork signed today, but kelly was at home with the kids so I couldn't pick it up yet. I'll pick it up on Monday..

kick ass and take names!!

#111412 For guys that have sound issues at race tracks.

Posted by Matt93SE on 28 December 2018 - 12:24 PM

I'm not sure which classes (if any) this would be legal for with SCCA since it could/would be considered an "active engine/exhaust modification" and likely prohibitied in certain SCCA classes.  however it's a damn cool idea for those places that allow it.


Laguna Seca is notoriously picky about noise since it's a start park and a park ranger is the guy who drives the microphone.  They have little (zero) leeway.  Many people were DQ'd during SCCA runoffs for blowing sound during the race.  multiple people from TX were leading races with just a couple laps to go when they get popped.  UGH.


Around TX, there's not much enforcement at the tracks where SCCA races, and my RX7 is right up there against the limit if I have the exhaust aimed at the mic.   I have a ~45deg turndown (turnaway?) with a couple different positions available so I can aim it right or left.

Places like MSRH will run both directions but the sound meter is always in the same place- on the inside of the track at one of the cutoffs between the launch and gut check.   I simply adjust my exhaust for the direction.    TWS always ran the same way, but they would put the mic on left or right side of the track depending on the event.

NOLA is almost always on the left side at the end of the front straight, so my car is basically at top speed.   the good thing is at that speed, I'm in top gear and have the fewest revs/mile (feet / brap?) so the engine kinda sorta makes less noise, but it's also near redline as well.   to the bystander, it's screaming; to the microphone, intensity doesn't change much per RPM- only the frequency.


Anyway, the only time I had a problem with sound anywhere in TX was when I had the exhaust aimed the wrong way and got a furled black during qualifying at TWS.   I saw the sound sign and furled black, so I just short shifted and ran part throttle through there for the rest of qual and then turned exhaust for the race and was fine.

#110540 Kicking the Hornets Nest

Posted by Matt93SE on 20 November 2018 - 10:21 AM

You had me at "sideways the whole time" and then further sealed the deal with "big boy pants".  This is exactly what I need in my life.

Fun on old tires with Caterhams... 

#110538 Kicking the Hornets Nest

Posted by Matt93SE on 20 November 2018 - 09:23 AM

I definitely felt ABS kick in when I had it enabled.  It wasn't necessarily intrusive though.  This probably sounds stupid, but I'm kinda OCD about trying to chase a pure driving experience with little to no computer aids.  The challenge of mastering threshold braking without flat-spotting tires is part of the allure for me.


The ABS hate started when I was really enjoying a rain session at MSRC (with ABS kicking in frequently) and my instructor said, "Good job, but try doing this in the wet without ABS like on my NA Miata."  This was the "hold my beer/challenge accepted" moment when I decided to disable ABS and prove to myself that I didn't have to rely on ABS to save my ass.


Maybe I should just buy an older, carbureted car with no computer aids to chase that experience?  In the meantime, I'm going to try to find ways to take my relatively modern NC Miata back to the stone ages.  However, it seems that my ABS disable solution is not the right approach per Derek's feedback - so I need to do more research there.


buy my first gen RX7..   ~200whp, ~1800-1850lbs (without driver. I've forgotten how much ballast I have in it to get to 2190 w/ driver).  solid axle, no ABS, no traction control, no power steering.  A proper driver can do 1.42 at MSRH in it, possibly faster- but you'll be sideways the hole time to make it happen.  Put on your big boy pants and drive a REAL race car.

#110368 Track event manager job

Posted by Matt93SE on 14 November 2018 - 04:44 PM

Posted on the Chin forum.


Has anybody ever worked in a position like this?  Asking for a friend.  You can pm me as well.

Everyone I know that's been a track manager or event manager wants to shoot themselves.  ridiculous hours, gone every single weekend, long hours at a desk doing email, scheduling, and 'social marketing' when you're not gone..  I wouldn't touch it for less than 150k, and certainly avoid it if you're married with children and have an option elsewhere.


but hey, that's just me.
