1980 Olds 88 Coupe curb weight is something like 3300 lbs.  And when you paint them orange they look like this;

Seems like an open and shut case.

Which engine?  I assume it's been uncorked some from the original power?  Converted to rack&Pinion?

No need to convert to R&P if the front end is in proper condition. A 9C1 gear is a bit quicker from the 88-90 Caprice and has a good feel. The front suspension is so adjustable you can dial in whatever you want. 

Power? What do you want? Anything fits under the hood.

My 89 9C1 weighed right around 3500lbs and was a 4-dr, iron block, iron head, iron intake, iron exhaust manifolds and rpobably lead elsewhere.

I had a 1982 olds delta 88 that i took to the 2004 Challange, i had a lot of fun with the beast. Great car for the size though. I had the 307 that got a bigger  4barrel and headers and moved to a th350 trans. and better springs and added rear sway bar.

Are you allowed to replace pads during One Lap? That would be my concern with some of the GM suggestions - being able to fit enough brakes under the car without blowing his budget that can stand up to multiple track events.  But if you are allowed to swap in new pads for each day, then maybe it could work.

and that has me sending my own thread off-topic... but is there a... codified (?), centralized (?), linkified (?)... that as it were, is there one place that I can view all the results of all the previous GRM Challenges?  (looks like I can googlefu around a little and find 2011, 2014, 2015, and 2016 pdfs)

You've touched on a Peve of mine.  No, there is no Challenge Hall of Fame Page.  There is no one place to see all results from all years.  Heck, there is not even a one, single place where maybe all the past written articles could be read (which would seem to be the easiest way to do it.)  

However, in this thread, by page 3 there is some recalling of past vehicles in The Challenge (but no record of their finish place).

Pads are "unlimited"... only thing required to be purchased from TireRack are the tires, and they're the only item that requires "event staff approval" in order to change.  Changing pads every day only costs you out-of-pocket money, time, and essentially sleep/prep (i.e. track walking time)

Is it odd that my only real desire for one lap is to take some random bone stock turdbox and see how far it can go before dying an unholy death?

I've questioned how the magazine uses some of these events in the past.  The UTCC coverage is about the same.  So much missed web content/ potential ad revenue there, IMHO.  Maybe have the Challenge and the UTCC be their own websites, linked to from the main site, where they can be an archive of past events as well as a place for news/rules about upcoming events. Event sponsors could get preferential ad treatment on those sites and help pay for/justify the expense.

Which if you have a dedicated transit driver/pad changer it isn't as big of a deal for the racing drivers.... 

Man it looks like I'm not putting a trans in the truck this winter.

So, just the car is double Challenge budget?

For a second I was like, "Eh, he realizes the entry fee alone is $3000, right?"

Well a "bone stock other than EBC blue pads" 09 civic si made it 3.5 days and 9 scored events (mostly 'cause the drags were early this year) before completely dusting the pads.  So, I'd guess in the 1-3 days timeframe... unless you kept changing pads as mentioned here.

2018 will be my 6th participation in OneLap.

Current budget outline is:
$4k - car
$1k/person entry
$800 hotels = $265/person
$600 fuel = $200/person
food is "dutch"

edited to single-line these costs

With the right pads, changes shouldn't be necessary.  IIRC, mazduece had none with the V, neither did Sonic with the C63, and neither did I with the TL.  Most Carbotech/G-Loc/Porterfield compounds are "good enough" or better on the street while having better friction at temp... although, ymmv (do your own he/tests)

Technically challenge has its own domain.  But the results are saved up on CM webspace, afaik.

I have a similar inclination about these things.  From 2003-2009 I co-founded and ran an unaffiliated 3rd-party news/stats sight for a small engineering competition I participated in during college.  I felt like the official site wasn't getting enough info out from past competitors... which put new competitors at a disadvantage.

Trouble is, you've really got to do this through the organizers... otherwise things tend to get complicated.

Nice!

Yeah, the price of the event is what kept me at bay with a few previous cars I owned that would have been to do with.

I've got some experience with mixing up who brings a car, how it gets built, and the intricacies of navigating all that is OneLap... and I'm going to try and avoid most of the pitfalls of that in this build.  Although, I'm a bit new to this whole "public" build... discussion... thing, so I'll probably fall into other pitfalls.

None-the-less, in the same way that a OneLap Q45 is "John's Project", I feel like a OneLap 9C1 and/or C10 are a "Bob Project".  I look forward to driving either or both at OneLap if/whenever that chance may be.  However, I think any 9C1 I prepared would be "off"... or even possibly "wrong" once you got in it.  And, assuming you come along, I'd prefer that you're able to focus on picking up the lessons that a first-hand OneLap experience provides in taking on your own attempts... instead of being frustrated with how that 9C1 is prepped, or if a Sonata's transmission is about to eat itself.

That's part of why I'm relatively laissez-faire about performance.  I'm more focused on education, experience facilitation, and expanding the "what can an average person bring to OneLap".  I have a few other minor experiments I'm thinking about attempting, that'll push beyond what I managed with the TL... but they are tertiary at best.

So, that's a bunch of words... some of the big, hopefully you can appreciate what I'm getting at... and similarly the rest of the board

That 3300 lb weight was probably with an Olds 307 or Chevy 350 under the hood.  All iron. 

They're not so crazy heavy for their size and the formula was honed for many years.  Impala SS, 9C1's, and other related vehicles can donate parts to the cause.

Many (most?) people bring spare brake pads, but few need them. We needed them this year due to lack of testing. It turns out 20 minute sessions with the "medium" group at a track day aren't even close to the abuse we throw at a car in three laps at One Lap. I kind of knew that, but it was a good data point and we got away with it. I've watched enough cars hit things in One Lap now that brakes and safety are at the top of my list. The next car I build for One Lap will have a half cage and seats/harnesses.

I thought of something else less well known. 01-06 Elantra and the 04-09 spectra/5. They don't make a ton of power (130-140whp) but they do handle a 75 shot of nitrous. What size wheels do you have? These cars are 4 bolt but a set of tiburon front and rear hubs and rotors fix that as well as giving you the larger front brakes. Could get one down to 2600lbs or so. Rear seat room is surprisingly good as well. And like the rest of the by/Kia group there's lots of cross platform parts for them.

I've got:
4 - 4x100 Enkei RPF-1's 15x7 et42mm  (iirc) {these have about 15kmi on them, and have done 2 OneLaps} silver
4 - 4x100 Motec Nitro 17x7.5 et40mm  (one has a bent lip, but it still holding bead, ran OneLap on the MINI, black)
2 - 5x114.3 Motegi MR118  17x8 et32mm - black
4 - 5x114.3 949racing 6UL's  17x9 et48mm - gold

looks like i've got more research to do

I know that 16x7 +40 clears on the 01-06 Elantra, not sure on the Spectra but I suspect it's similar. Stupidly they are 4x114.3 so there'd have to be a hub swap to the 5x114 but I don't think any of those would fit. 

 

EDIT: the 17x9 might, but I bet you'd need to do some fender cutting to make it clear. I had an 02 Elantra and 17x7 +38 with 215's would rub the rear bumper tab on compression but there was room inside for the wheel and tire to fit.
