Can a mod move the stuff from skyactive to here?

Factors
GT-6
GS-9
ST1-12.5
ST2-15
ST3-17

Guestimates of my car 190hp (crank) so 170 wheel (optimistic). Weight, guess 2300

ST2 = 170*15 = 2550
My weight with gear 175 (optimistic) LOL

So need to add 75 lbs to car, not bad.

OR

ST1 = 170 * 12.5 = 2125 ... Need to make car weight 1950 (didn't see much places to save weight on the car). OR add HP (meh not worth the headache).

If my car only has say 165 hp (possible) I'm DEAD on the weight! No changes needed.

Getting the car down to 1950# is really hard. My Jetta used to weigh that, but that was a long time ago. Since changed to a beefier transmission and if I continue to race this car I will likely have to change my engine to a 1.8T.

Think about other driver comfort things you can add. Cool shirt system, fire extinguisher, A hard wired radio maybe. All adds up. Since we got a CM200 blasting out some serious watts the driver never has a problem being heard down in C6. Sometimes reception is a bit flaky down there. Radios are a must for the Enduros. As is the coolshirt.

I'm looking to go 1.8T, car an driver weighing in at 2250#, 180hp and racd in ST2. Though, with the 1.8T engine, I can pretty much dial in whatever hp I need if I end up making the car heavier.

LOL with a 1.8T you can cheat like everyone else with a turbo will.

Get Dyno, then switch tune during race. It's going to happen, only a problem if you get caught.

Oh and you can't have 180hp and 2250# and race in ST2... You need to be minimum 2700lbs to race in ST2 if you have 180hp

2250 - 180hp is ST1

Yeah - I need to either get my car to 2088lbs (including me!!!) to be at the top of GS, or add ~250 lbs to the car to get it to ST1....

232whp*12.5 = 2900lbs
232WHP*9 = 2088lbs

Current weight=2453lbs + driver, etc....

I think I know what I'm going to do but yeah, should be interesting. Still planning on doing the FG hood & trunk. Then I'll be able to play with the positioning of the ballast weight to get the best weight distribution.


Or, I run SPC and get the shitty tires and just have fun :)

Why not rev limit for dyno or something?

Yeah that's the other option, restrictor plate

My understanding is that you're going to have a GPS in your car.

They'll be able to calculate "approx" HP from your acceleration potential & your weight so no cheating!!!

Honestly I'd rather add 250lbs than reduce my engine output.

90% of the time I'm on track I have a passenger (150-200lbs) so an extra 50lbs on top of that won't make MUCH difference.

They will most likely stick them in the top cars but not all cars. Unless they mandate everyone to buy another system (that would suck!).

I've got a traqmate which does this already, the calculation is way wrong, gotta be something in the software as it always said my car had 80hp lol

I like the traqmate system though and CTCC uses it ;)

^SPC requires all cars to be outfitted with a series-standard GPS/data logging system. I could see CASC requiring the same thing.

I've been saying all along that one needs to run restrictors. It's a no brainer. Ya, takes a bit of work to fit them. Oh well.

And ya, my mistake. 2250# and 180hp puts me in to ST1. Will need moar tire for sure.

Hey Shawn, straight OBD1 conversion with no M3 cams and stock flywheel and pulley. Guesstimate likely between 200-205 whp. Does that sound about right to you?

If so then I might squeak into ST2 this year which would be nice. But next year when I build the proper motor I will be hooped.

Is there a tire rule? or is it a free for all on grip?

wing

No tire rule.

I still think it's better than the old system where sand bagging was key

There was supposed to be a spec tire but some douche on the CASC board wanted his palm greased. A lot.

It's gonna throw a wrench into this mix for sure.

for example, at bogie, I've got 6 seconds a lap difference between hoosiers and a RA1 type tire. If you want to win, you're going to need the uber rubber.
I don't see any alternative. unless I'm missing something?

wing

So spec tire is Hoosier ? ;)

Problem with spec tire I guess is it really starts to make the series inaccessible to some. Also with a wide variety of cars, some cars may not have a tire size to fit.

They could perhaps mandate a range of tire sizes so st3 cars aren't running 305 wide tires

another dumb question, Sprints classing stays the same? So how do you share a car over the weekend in challenge and sprints, or participate in both?

wing
November 19th, 2012, 08:57pm
This is confusing, yeah sprints stay the same. Sprints are 20 min right? And then challenge are 1 hour races?

One guy just commented about that on casc. Build car for challenge then sand bag for sprints.

Not sure i want to do challenge yet, sprints would be first step to ensure car reliability and driver reliability lol.

Or just run bogie series for best bang for buck? I think id like to do at least 1 or 2 race weekends, very least ted powell

Nope that's too high I think - you're looking at those numbers once you have the M3 cams and a tune. just the OBDI conversion gives you 15-20hp IIRC, so you'd be looking at around 180HP is my guess.

That's the one and only race I will be doing next year.

I have 176hp at the wheels now. It's a stock 2.8 and I dynoed it at Tapp's. So 15-20 gets me to 191-196. Close enough to what I need in stage 1.

sb_915
November 20th, 2012, 01:32pm
whoa - if you're doing 176 at the wheels stock, then you're motor must be pristine, or the dyno reads high - that's crazy good!

It's what I'm thinking but I may head out to other places. iCar is close as well and a fun track. But I've watched those crazy frenchmen race and it's crazy.

Stock the 2.8 was 192 at the flywheel, and was either underrated, or the engine "breaks in" over time and produces more HP. But my gawd does that block pull hard, compared to say the one in Rusty. Mind you that block also felt pretty tight compared to a couple of others I've driven. If I can get 195 this year at the wheels that will get me into ST2 with 50-75 lbs to spare I think, won't know till we weight it all.

Who wants to buy some scales :D
