.....Monday Afternoon, right after lunch.......

Spanky: (Walking through the front door)  Dang, could it get any colder out ther'.  My toes 're froze, my fingers 're stiff, an my dentures 're freezin to my lips.  Hey Ms. Lynette, that still our Cobalt parked in the customer parkin lot?

Ms. Lynnette: Hold on, what you goin on about Spanky.  You think its cold out, every time one a you fools goes in or out I get a nice little draft under this desk.  You better let me bring in a heater or somethin, my feet are cold.  I'll call down an see if Fit knows about that car.  The keys have been in my desk since he got back from Sebring with it.

Spanky: Hell just give me the keys, I'll move it.  I need to go an see what that fools been doin anyway.

Ms. Lynette: (Tossing the keys over the desk) You better close that door quick, I'm already warmin up.  You still there Doreen.....

Spanky walks out in front of the showroom.  He fiddles with the remote for a few minutes, cussin that the door handle won't unlock.  Finally, he uses his brain and decides to stick the key in the door.  Viola, he opens the door and slides in the door.  Ms Lynette is watching over her desk, curiosly.  She can see him smackin the dashboard, beating the steering wheel and soon he flings the door open, jumps out and slams it shut.

Spanky:  JOHNNY, JJOOHHNNNNYY.  Git yer butt up here an bring the jump box, damn cars dead its so cold out.  (Johnny hobbles up with the jump box) Head on out and git that red Cobalt runnin, I'm 'a run down and check on Fit.

Johnny Rotten:  Alright Boss, be right back.

Johnny walks out front pops the hood open.  After about a minute he starts scratchin his head, literally.  Spanky is looking out the window with Ms Lynette and neither one quite knows what the old man is doin.  Johnny notices the audience, throws his hands up and starts back in side.

Johnny Rotten: Hey Boss, I bet you this car has a "check engine light" on.  I ain't gonna be able to get this one started.  You best have another look.

Spanky: You gotta be kiddin me, all your 'sperience and a little dead battery is kickin your butt.  Gimme that box, I'll do it.  

The two men of the shop walk outside.  Spanky pops the hood again and Johnny just stands there laughin his "I told ya so" laugh before the coughin takes over, but not before he's completely pissed off Spanky.  Johnny heads for the showroom while Spanky storms off toward the paint shop, fumin.

Spanky: Fit, FIT, git yer lousy ass out here.  FIT!!!  Lousy, no good, rabble rousin, worthless, con-founded, nerve rackin, ungreatful, butt touchin, dirty little son of a....

Fit: What are you goin on about?  You know I have a customer in the back.  You'd better keep it down.  What do you need?

Spanky: What part of stupid makes you think you can park a car in front of the showroom with NO ENGINE.  Its 21 degrees outside and I've been tryin to get that Cobalt out 'a the customer lot.  Come to find THERE'S NO ENGINE.  Johnny's havin a grand ole time jokin about it, Ms Lynette's feet are prolly froze from us goin in and out of the front door and I'm gonna need at least a cup 'o coffee or three to git my inside warm again.  You finish whatever it is yer doin and get in my office.

Fit: (With a snide look on his face) I'll be up as soon as this car is tagged, now get outta here and calm down.  I'll go try and salvage some respect from OUR customers.

Seems the motor from the Cobalt found its way out (your welcome Oldschool Speedshop).  Spanky however wasn't in the loop on this one and picked the wrong day to do something about it.  With only a short amount of time to figure something out, Fit had damn well figure something out.  But what to do with a perfectly good Cobalt but no Engine???

Ooh, sounds fun....got a class picked out yet?  IIRC, this is similar to the Pontiac Sunfire GT, a great little car that was the victim of bad marketing-a more masculine name would have made it a real crowd-pleaser.  Anyway....I'll be looking forward to the details.

Had a while to tinker with this last night.  Still in the toon phase.  I am amazed at how well this car does.  I built the car and ran it on the QR tracks.  I've determined that it is gonna be my Flowing track car in A-class.  But why??

In stock toon, everything untouched I was able to beat my Panoz time around Maple Valley Long, not by much but this car is in STOCK toon.  Took it over to Mugello Long just to stretch her legs and was within a second of my Lotus Exige 240 Cup time.   :o  I spent hours on that car getting it into the 111's on that track.  I beat my TVR Tuscan S times on Mugello by over 2 seconds, again this car is only built not balanced, biases or Tonka Tooned.  I can't begin to tell how happy I am with this and what a welcome suprise.

Still Coming Soon!!!

The Cobalt took me all the way through the professional B class in my first run through the career. It was my meat and potato car. Glad you're having fun with it, Fit.

I had about 25 minutes to play around with this last night so I went back to Maple Valley for some laps.  I'm still running the default toon with the exception of 20lbs of downforce on front and rear.  I was able to better my time by about another second.  Off to Mugello to see if the added downforce helps or hurts.  It hurts, bad.  I lost about 1.5-1.6 seconds.  I was still at the same speeds on the straight but I think I was the problem. 

It didn't help that my wife was "enticing" me to retire early.  I had put together the build list earlier in the evening for the thread in the daught net and wanted to quantify it a bit for this one.  Fortunately my wife won out and I went to bed a little early  ;) Friday night should allow for some more Forzacating, after the womens match that is.

Updated the toon and its still a WIP.  I'm not sold on the high rear camber as I believe that is where I'm losing so much time on Mugello.  The trans is still the weak point and I'll be finding the Getrag gearing for that this week.  Turns out the downforce was a big help I was just out of kilter.  I found my second on Mugello and was into the 1:55's again today.  I do think that I can bring this thing around some with the trans as all of the weak shift points are evident on this track. 

I took the car online and ran Maple Valley with fndrbndr.  I got smoked by about 3 seconds.  I started making mistakes in an attempt to squeeze a few tenths out of it.  Not a great showing.  I get the notion that I have a bit of work left to do.  I may need to play with the SWR a little.  But I'm not sure how yet as this is the first car that will get that theory applied to it.  So far its going well but I could easily make it a pile of garbage.

I've been at this one car for a while and I've been trying to pay close attention for the daught net thread so I may need a change of pace in the near future.  Still a WIP

Had a short amount of time to weak on this thing last night and I think I made some progress.  I went back and set the SWR up 0.5 to 76.25.  I then removed 0.2 form overall camber.  I was trying to find the effects on long sweepers so I ran MVS as a test track for the settings.  I gained 6mph on the long sweeper and was on par to make up over a second over my baseline time when I stuffed it. 

I think you guys are on to something with the correlation between suspension stiffness and static camber.  I'll run this thing again on Friday with the gearing Snyder suggested and see how close this is to a total package.  Its coming along nicely, I must admit.
