Bavarian Rallye Challenge: The Real Deal [FINISHED]

[strop]

Phew thanks!

I shall await results then!

[darkstrike]

Will the results be posted to this thread, or a new one?

[Der Bayer]

I'll probably put the results in a GoogleDocs folder this time. Links to that folder will be posted here.

Since entries are now closed, here's one of the engines I came up with, but decided not to enter because of the small size of the powerband and the poor driveability

Well, this is what i entered with:

[EnryGT5]

Wow, i didn't think it was possible to hit 600+bhp, my turbo power record is 460-500bhp, drives really bad compared to the 415bhp N/A thing that took me hours to optimise, the one that i entered

[strop]

We had similar issues with 600+hp motors, it's true that the wider powerband turbos did much better, especially in the slower tracks. I guess we'll see how it all goes!

From a high of 565 hp I dropped the power down to 470. turbo is spooled by about 3800, power peaks at 7700 and redline at 9500, its nice and quick through the bends, lots of power band to play with

[OCAdam]

Well, this is what i entered with:
(picture removed for quote)

Seems we have extremely similar amounts of power, though my torque curve is quite different (and lower, at 492 Nm).

Interesting.. I tried to make a V8 engine, but I felt the mid range power wasen't enough..

This is what I entered the BRC 1100 with.. I fear it won't be the most competitive engine as it was designed for a good mid-high powerband that sacrificed overall power.

[Zabhawkin]

Here is my engine and car. I'm not expecting to be in the top 10% but am hoping to have done decently.

Its at least a relatively efficient design.

Sadly I am not at home I am at college and this laptop does not have automation BUT I do have the files since the PM was sent via the chat PM. But I am only going to post that if others do.

As far as my cars. The engines are very cheap and only use iron for the lower and upper end of both cars. Makes for a heavy engine but it was well within the cost and manhour limits required for the contest. The BRC 1100 engine produces 498HP and has a usable power range of around 3k or 4k of RPM with a redline of around 10,500 RPM. My S1000 car has around 148HP with a similar powerband range and a redline of just over 11,000 RPM.

Both cars are made using the absolute lightest materials possible as a result I just started adding adding safety gear and so on to both of the cars to reach the weight limit. So my drivers are some of the safest in the contest. The S1000 car ended up so light that I had to add a hand crafted interior, premium safety, a standard entertainment system, and halfway up the sound proofing just to get it to the weight limit (even using engines 20% to 30% heavier then anyone else). So yea... a 200kph, 0-100 in 5.7 seconds, and 1.25g at 89kph luxury sitting room. Comfy

The engine for our Super 1000 class entries ended up to be quite heavy, as did the platform, so I couldn't get my team's models down to anywhere below 900+kg..

[Dragawn]

I opted to go with a very torque-y V8 with a flat powerband, just to hopefully make good use of the V8 power, whilst keeping some driveability.
Seems like some really interesting concepts everywhere.

Some interesting engines in here..

This is a prototype V8 I tested for my BRC 1100 car... Despite looking decent on paper, It just couldn't match the I4 I posted above. It was like 9 seconds slower on some of the test tracks I tested my cars on.

Looking at it now, I think the main problem is despite having a higher redline and better top end power curve, the torque drops off too quickly and this might be causing slower acceleration at high speeds. In comparison my Inline 4 has a rather flat torque curve from mid-high RPM.

EDIT: Lol, I just realized it has 450, not 550HP... no wonder it was so slow.. Hmm, I must have done something wrong in the design to get such weak power.
