Jim, gotta change the SR rules for IT. The SR20DE-powered B13s got moved to ITA for '05. As for right now the following SR20DE-powered cars are in IT:
ITS
95-97 200SX SE-R at 2625# (currently under proposal to move to ITA at 2490#)
ITA
91-93 NX2000 at 2515#
91-94 Sentra SE-R at 2490#
With that in mind, I suggest changing the rules to read as follows:
Improved Touring Exemption for SR
In order to open the SE-R Cup series up to more competitors, all SR20-powered B13 and B14 chassis vehicles currently racing under SCCA's IT classification are considered eligible for the SE-R Cup in SR class. Participants wishing to use this allowance in SE-R Cup rules must:
a) Possess a current and valid SCCA log book for the vehicle.
b) Verify in writing that the vehicle complies with *ALL* SCCA IT rules (except for signage).
No cross-pollination of IT and SR rules will be allowed. All vehicles racing in the series must either comply fully with SCCA IT rules, or fully with NASA SR/SRX rules. Competitors wishing to participate must still obtain a NASA logbook, undergo a NASA annual tech inspection and comply with NASA competition licensing procedures. Four NASA stickers must be placed on the vehicle in compliance with the NASA CCR. All SCCA decals must be covered
or removed.
The Series Director and all NASA officials retain the right to exclude any vehicle deemed unsafe from competition.

Ok, thanks. I'll post another version later this week. There's always little things like this that I miss, so look for V3.77 soon. Basically nothing has changed, just spelling and stuff.
so, not only will our P10 be weight penalized, but it will also be power penalized? that doesnt seem fair. the P10's only advantage is its suspension.
in addition, we are already saddled with a lower final drive ratio. this will make the car dog slow on the straights. of course, once we get the car built, i guess this can be changed per the rules. my prediction is the post 1:16 penalty will not be necessary.
Wait a sec: same power-to-weight ratio but a superior suspension, and you're surprised at a 100# penalty...? Frankly, I'm surprised it's *only* 100 pounds.
no, its NOT the same power to weight, that's the problem.
the 100lbs is excacted after power to weight. so, a 2360 lb car is allowed the same power as a 2260 lb car. coupled with the gear ratios makes a slow car.
i don't think its suspension is superior enough to warrant that much penalty. but, like i said, we will find out, one way or another.
Don't start bitching now, Rob and I have been telling you forever that it is going to be 100 lbs.
100 lbs before power to weight isn't a penalty at all- look at all the heavier, faster cars out there. With 11" brakes and 225s heavy cars should have no trouble in the Cup.

bah, i knew it was going to be 100lbs, didnt think that would be after power to weight though. i doubt i am going to be able to get the car below 2360 with driver anyway, i just think my car will be slower than sh*t with the longer final drive, longer 3rd-5th and effectively 6 less whp. this will prove an extreme handicap on tracks like big willow and buttonwillow. if i can swap trannies to an SE-R tranny, then it won't be that bad (probably won't even notice), but if not, this car is going to be useless and i might as well get an SE-R if i want to finish on the same lap as you guys...
like i said earlier, as long as it changes when you find out my car is the slowest on the field, im cool. i just think you guys are being a little too hasty when you haven't even seen how much of an advantage the multilink front is.

I'd rather upset one new driver than a whole series of drivers. This is what you get for not wanting to race an SE-R in the SE-R Cup.
Once your car is complete and built to the same level as other cars, we'll probably have an impartial NASA official test drive and re-evaluate things from there. If the penalty is too much, then by all means we will change it- probably mid-season. We'll probably re-evaluate again at the end of the season, too, just to make sure we have it dialed in right. Don't worry, if there is a playing field imbalance, it won't be for long.
If your car is the slowest in the field because you are the slowest driver, however, then you're not going to get much from me other than a "Go gettem, tiger!"

Reason: They're grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrreat!

how about a nice glass of "shut the hell up"?
that's all i wanted to make sure of. like i said, it is my prediction that the car will not be so fast as to warrant the penalties. i think our car should be tested back to back with another "fast" cup car like tony's. obviously, if you test my car and will goo's (no offense will ) back to back, i will be swatting the damned pinatas off me the whole race.
also, does the "cross pollination" of parts clause apply to this where i can switch to an SE-R tranny? this would save me money (the nismo diff for the unlimited slip case is $1000!) and get rid of the retarded "luxury" ratios in the P10.

You can use the se-r ratios. I would not sweat it, my car is 100 lbs heavy and I have won races, qualifed on the pole a couple of times and am always a contender to win. Naji is always right in their as well and he is about 60-80 lbs too heavy.
Getting the basic car prep is important and so is driving.

you were allowed the same 16:1 ratio as everyone else.
i am not going to sweat it though, i will just build the car according to the new rules. if it turns out to be too slow, then i am sure the rules will be changed. i just needed some reassurance that i wouldnt be investing thousands of dollars in a car doomed to failure because it was mired in weight penalties.

Actually, I believe the Dog car carries a 75 lb penalty and is competitive. So I am pretty sure a 1% difference isn't going to break your back.
I'd say use the SE-R tranny. It isn't specifically laid out in the rules, but it is implied with the B13->B14 stuff. Just don't do anything fancy like mix the G and SE-R gears to gain some kind of advantage- just stick with the stock SE-R box (with an NISMO diff, of course).

NO! never! that 1% will allow you guys to lap me!
i don't plan on using ANY P10 gears. i don't think it would create any advantage. the only gears you could individually swap are reverse, the final drive (why would i want a steeper final drive?) and 5th (how often do we use that, and do i really need a 5th capable of 180mph?). 1st-4th are cast into the input shaft, so that won't work. a long reverse would be nice, then i could drive in reverse and have MAD RWD DORIFTO POWAH!
we will be doing a lot of testing on the stock tranny, i believe. we want to hurry up and get this car at least into some HPDE events. as soon as the suspension is on, its on like donkey kong!

Yeah I forgot my car does carry a weight penalty for the shock towers and side windows. Beter not lighten it anymore. Thanks for reminding me.
I'd say that on our level is better to get your basic prep right, become a good driver, then worry about being light.
