waiiiitttttt
those price limit...... that's for the race trim?

if it's sooooo..... then i just totally derped

How badly are you over budget?

[DoctorNarfy]

If I where to take a guess, (because I had this issue as well) they didn't see the budget, because it's hidden at the bottom, so they just went "Carbon fiber +15 Everywherrre!!!" Which is why you always have to eye the rules very carefully in these things

about 89000 total cost
not as bad.... i didn't use carbon fiber and +15 everywhere

and i was making the AGTE class car. so instead of just redoing it from zero, i just need to redo an entire trim

nah.... it's just.... there's only 1 price limit, i thought the price limit was for the production car..... not the race car......

I've done a quick test as an AP2 entry, and I find it rather hard to reach the 900KG limit. The closest I could get was when I built a 3.3L engine weighing around 90kg or so. Seems to be a bug as I couldn't replicate this?

I was a few grands over the price limit aswell, but not as bad as koolkei

I'll try to spend more time on it, but I can't guarantee having a proper entry before the deadline.

Has anyone managed to have a 900KG car under the 30K price? And is it that hard or I'm just being a noob who can't just make proper lightweight cars?

I wouldn't say alot of bodies can manage it, and I guess it would reduce the variety between every opponent? Well at least the F40 look-alike (80's supercar bodywork?) has hard times going at the weight limit.

I just compensated for extra weight with extra grunt

I just ran a quick test as well, and it is possible, I make 800ish kg car under 30,000 so it is possible (with safety of 52), but diffcult and you compromise some aspects of the car. Try to choose a quite small car body and choose carefully the panel and chassis materials, and you will get pretty close. Remember that 900kg is the minimum weight, there's not a maximum weight set.

I will include the prices in the OP so this doesn't happen again

oops, I should specify that. The cost is for the race trim, your production car can be more expensive, and even more powerful (like some GTE cars that are detuned in comparision to the production version).

[iRaptor]

Oh I see. Yeah the car body I chose isn't small at all for sure. I will surely spend more time on it as soon as I can. But yeah it seemed logical that 900kg was the min weight and not a max weight. But Light is Right

[iRaptor]

Just noticed something on AP2 rules. If you have a production car with your company, you can effectively take the loophole of using the engine of that car to allow the use of a bigger engine than allowed, and therefore being able to use 5L turbo engines, which seems to be under the rules? I know power is limited but it would make for some serious torque/economy monsters it seems :O

Well I could go for that, but Mr Chapman will probably not be happy :/

Just noticed something on AP2 rules. If you have a production car with your company, you can effectively take the loophole of using the engine of that car to allow the use of a bigger engine than allowed, and therefore being able to use 5.5L turbo engine, which seems to be under the rules? I know power is limited but it would make for some serious torque/economy monsters it seems :O

Acctually for the AP2, both production and "original" engines are set to 5000 cc maximum. I think is not quite explicit or clear, but if you take an exisiting engine, you're supposed to modify it to meet the regulations (2015 variant, NA 5000cc turbo 3299 cc, loudness 70, etc). That's why the rules are divided in "eligibility" and "regulations". Acctually there is a loophole (that can give you a quite special bonus) but is not that one.

A 900 kg can have a maximum of 495 hp, wich is acctually quite low, a little bit of weight can give you more power for those really long straights (le mans, green hell)

POWEEEEEERRRRR

but more Grunt takes the Run


atleast. that's the approach im trying to do...... since small and light and agile cars takes a lot of fine tuning that im not good at. im gonna try going brute force

Well I edited my post just before you replied as I noticed I put 5.5L instead of 5L. But now I catch the whole thing. I thought that having a production car would give an unfair advantage engine wise
But it seemed unclear as the AP2 Word page actually stats the max displacement is 5L, and any aspiration is allowed.

Green Hell is not all about straights though

I don't think I'm going to be anywhere close to the 900KG limit with the body I want so I might have to use more power indeed. Power won't be an issue, but packaging is.

Still got plenty of time to take care of it though

Brief update.
The regulations in the OP are now in both metric and imperial system.

[Vri404]

This is going to be great. I won't know the results for the first three races until the 20th of December. Yay for travelling!

Anyway my bananas will probably place quite low, due to quite a bit of weight and not that much power. GG me.
