was it your car that took second this year in asp?

Only technically speaking. The Miller's Evo had cooling issues (radiator hose blew off) on day 1 causing Aaron and Frank to only have one run each. On day two they each took 1 run in their Evo before cooling/engine issues struck again (likely damage from lack of coolant the day before). This time though Aaron jumped in my car to get a second time in the books for the day. His fast times on both courses were set in the Evo. He actually was slower than me in my car although he admittedly doesn't have experience in anything other than turbo awd cars.

I imagine if he had more seat time in my car though he would have been right at the top with it. The car was just hooked up out there this year.

This weekend im going to run my first autocross event:excited:

Let's see what happen :stirthepot:

I was there in STX.

Worked impound when you ran, was the car a little pushy?

Hope this car goes to STU :D

Not that I could tell. Actually very neutral in my opinion.

i found a good photo album

I'll be there next season. With some of these cars I may even stay on the days I'm not racing.

Jen Wong who took the photos in that gallery is from the next region over from mine. He often comes to our events.

What class will you be running next year? Hopefully ASP. The purple crack is fun.

GotCone.com News From The World of Autocross, Rallycross, Rally & Motorsports is also another great site to see some pics from Nats.

B-street. I feel like I need to prove a point.

Honestly not sure why anyone would want to run a 370z in BS. It's just not competitive in BS and I don't see it being any better even if it went back to CS given how quick the ND Miatas are. The 370z has run its course in the street category. Once it gets moved from STR to STU I think the platform will make a comeback in the autox world though. Until then a few of us will continue to campaign them in ASP and hope for the best.

By the way, I'm assuming the point you want to make is that the 370z is classed wrong in the street category.

lol, that may be what it ends up being at the end of the day:rofl2:

It should be in FS.

My nats video, in a slower car.

West:


East:

The pony car guys would love that. Although with the current crop of pony cars it would be interesting.

A fast FS time would have been a high trophy spot in BS.

What is it about the 370z that makes doing well in BS on a national level seem so impossible?

It would likely get beaten in FS as well. FS isn't four grades slower than BS, it's just another class. The more the HP friendly the course, the poorer the 370Z would do against the cars in FS, imo of course. Does anyone know if FS and BS ran on the same days and run groups at Nationals?

The limiting factors compared with a C5 Corvette are:

• 200lb heavier or more than C5
• Viscous LSD which doesn't allow the car to accelerate out of corners unless the steering wheel is nearly straight
• Very limited, non-adjustable front camber. (around 1 degree)
• Power/Torque band is great in the 50-63 MPH range (close to redline), but not great digging out of slow corners. This makes it more course dependent.

I ran BS and won our local BS class in 2016 (10 events) ahead of Brian Johns who is a national champion in ES and 3rd and 4th in BS the past two years. Also won Dixie Champ Tour in the 370. But our local courses were better suited for the 370z (more transitiony) and slick sealed asphalt. Beating one good driver is easier than beating 15. ONE of them isn't going to make a mistake while being in a better car. So even if you were perfect, you'll still be slightly off pace.

If your goal is to trophy at nationals or champ tours, you can definitely do that in a 370Z. If your goal is to win or be top 5, it's just not going to happen.

:iagree:

So performance wise what do you guys think the ideal street class would be?

IMHO there isn't one anymore. It was C street prior to the ND Miata.

I think what I am asking how far down would it have to go to. DS?

I hear all the criticisms and I think they are valid, but I think that because we know our cars so well we have a tendency to over emphasize their flaws in relation to their competition. If the car is capable of doing well regionally, at tours, and even getting mid trophy spots at nats, I would hardly consider competing in street to not be a worthwhile pursuit for the folks looking to autocross with a relatively minimal investment into a vehicle they may already own.

I think we all can agree it isn't "the car to have" though.

No chance it moves to DS.

I'm asking how slow do we think this car is.

I think the car is just fine in BS

Street classes need to be for "new and shiny" i.e. newer models that people want to own. The 370z just doesn't fit that mold anymore and as such if it's not classed favorably then so be it. There's always STU (hopefully) and ASP.

fwiw sometimes the SAC and SEB do a good job at following this mentality and other times not so much.

We're talking about running an M2 in BS next year....I don't see any 370z mounting a serious challenge to the cayman S or M2 from here on out.

This months Fastrack is out and it looks like someone finally realized the 370 belongs in BSP and not ASP. :excited:

Now to figure out how to go even faster. Stupid Miatas. :shakes head:

that's awesome

Just to be clear. BSP has been faster than ASP the last 2 years. The MazdaSpeed Miatas are insanely fast.

Also, I had nothing to do with this letter.

Meh we were faster than SSP/ASP in 2014, too...

...if you build a rulebook 370z....I'll drive it :).

How much power does a SP-prepped 370z make?

I imagine it would be over 350whp with the plenum, etc?

350whp is probably about right...maybe a bit more if you run it at the point of explosion on E85 like I did with the DE.

Although not my intention to **** on anyone here or otherwise...there is no reason a full prep 370 should not run at the front of ASP (excluding most pros). I personally don't think it should move, since it hasn't been proven, too me, that it is not competitive in ASP. Everyone said the same for the 350z in BSP, but that was shown not to be the case. IMO you can't reclass a car with a performance envelope, on paper, that meets or in some cases exceeds the current competitive balance if the class just because no one has built a rule book car yet.

That last 1-2% prep costs a lot of money, time, prep, etc and yes it will also be the point when the car starts to break, a lot, but someone needs to do it. As an example, we did 83 dyno runs alone just testing intake configurations for my DE BSP car. I would bet it had 250 runs on a dyno to maximize it to the SP ruleset. We probably could have gotten within 15-20whp with 10% of those runs, but not the powerband/max power without it. Same goes for suspension. I can't tell you how many times the shocks (Custom Koni, motons, penske all of them in my case) were off the car for revalve...along with any billion different combos of springs, bars, alignment, etc.

I forgot about the SP prep level, can you run a surge tank or a Holley hydramat in SP?

I think the 370z can compete with the Evo as well, but not being able to be competitive at pro solos would discourage some people, which is why I think it should be in BSP. But we already saw the SP is dead thread on the other forum :P

I want STU to happen for the 370Z, maybe i can bolt on some 295 or 315 to do some events in SP.

I'm......not sure my 2014 car wouldn't have run at the front this year and the 370 would make ~50whp more than my DE at not a huge weight penalty....so IMO it would be a favorite on "some" courses.

I still think the MSM is the car and I saw that in 2014, wrote a letter to have it bumped to ASP, which was denied...so I took it road racing.

I'm probably crazy but I would see the MSM as a better fit in CSP (ignoring the fact that ASP and SSP are supposed to be the faster classes). They make more power than the CSP miatas but also weigh more (from what I've been told). Also size wise they're equivalent. Let's just make CSP the all miata class.

There is at least one person on the SPAC that is in CSP (think there is two right now) and no way that happens unless all miata's stay on the same line...which means current CSP cars running the turbo motors. I don't see that happening.

I'd prefer just have them in ASP where at least they fit in with the turbo cars (for the most part...and the 370's/Caymans).

Well aware of this. Looking at the results from Nats this year though does tend to suggest the current CSP miatas and the BSP MSM's are pretty equal. Hell Billy and Neal both beat Edens on raw time.

370Z are classed for STU in 2018.

https://dk1xgl0d43mu1.cloudfront.net...pdf?1508769569

I didn't know the 987.2S were classed in STU already, not sure why it was such a big fuss to class the 370Z there.

The Official 370Z Autocross Thread
 

Is it official yet? Or just the recommendation?
https://uploads.tapatalk-cdn.com/201...2c8de9f69d.jpg

It's recommended for 2018. Which means unless the BOD opposes it, it will go through. The BOD almost never overturn a classing change.

There were a lot of cars in the class that justified the z being there as well. The STR classing was a misstep from the start.

woot woot. STU build after one more season in BS for me then.

With the stu move on the horizon, what range of offset would it take to fit a 10.5", maybe 11", wide wheel up front with a 285 or 275? I know it's possible to run that wide stock but I'm unsure what will need to change if we use a wider wheel. I know it has been covered in the general section but I am hoping for feedback from folks who use their cars the way I do.
