Awesome

No, Martin, the Hartley V8 is based on Suzuki Hayabusa cylinder blocks and heads (as is the Radical Macroblock).
But both engines have bespoke crankcases, crankshafts, drysumps etc.

It just says so in the video description, but it's a Hartley V8 in the Elise.

Maybe this one works better?



This onboard video has bad sound quality, but maybe for analysis purposes



The Ariel Atom V8 also has a version of the Hartley V8, but all the videos have commentator voices or music overlay

Super cool

Might need wider rear tires too

But it's awesome. Had a lot of fun already

Quote from Van Sterberkt :

Hi Martin,

I'm trying to recreate something like the Radical SR1.
Video: https://youtu.be/GN4JWKiXu7c

I've made a start with the Gen 4 RPE-Suzuki 1340cc inline 4 engine, but the max torque is available at a much too low rpm (currently 6068, should be around 7500).


Can you have a look at this? Thanks in advance!

Although the Radical V8 Macroblock is widely used and very similar in every way to the Hartley Maxi V8 I personally prefer the Hartley because of engine design choices:

• the Radical has the cylinder banks shifted away from each others, Hartley has a more elegant solution
  
• the Radical V8 has a 72-degree bank angle for packaging reasons. Hartley has perfect 90°, will sound better and have better harmonics
  
• The Hartley Maxi V8 has a little more displacement
  

Awesome! Looking forward to that

Thanks for the explanation.
I really hopw it is/will be possible to adjust the engine mass exactly.

Sorry for my ignorance, but do the black mass bars affect deformation in any way? I suppose not, right?


EDIT:
I hope you are not insinuating that the TC24-B1Z is expensive???
You can order one here for under 50 grand:

Awesome!

Another essential engine: OS Giken TC24-B1Z

3208cc. L28 cylinder block
Power: 420 PS@9’000 RPM
Torque: 40kgf/8000 RPM
Maximum revs: 10’000 RPM
DOHC 24 valve

Note the gear-driven camshafts

Listen to it revving to 10K:

Interesting!

Seeing the engine as a block in the editor there: Were you able to adjust the mass of the engine? That's a question that came up in another thread …

EDIT: Also, please kindly consider ditching the turbo V6 and swapping in this: https://www.lfs.net/forum/post/1973107#post1973107

I think the revlimit is about 10'500 Rpm

Apparently it IS acually possible to edit the weight in LFS editor. Now if I can just find the info again …

EDIT: hard to find. Someone asked exactly that question and someone (Scawen??) responded that you can adjust the mass of the engine. It was something about an american V8 being way too heavy for its size.

EDIT: Here's a YouTube link of an older 2.6l version of the engine:

I don't have a mod ready yet but I know what engine I'll be requesting to swap into an E30:

HARTLEY H1 MAXI V8 SPECIFICATIONS:

LAYOUT- 90 degree V8, flat plane crankshaft
STANDARD DISPLACEMENT- 3.1 liters (turbo), 3.3 liters (NA)
OPTIONAL DISPLACEMENTS- 2.5, 2.8 and 3.0 liters (NA or turbo)
WEIGHT- 96 kg
BORE AND STROKE (STD)- 81 or 84 bore x 74 stroke
COMPRESSION RATION- 13:1
POWER- 420 TO 520 hp at 10,000 rpm (NA)
TORQUE- 240 to 280 ftlbs
VALVING- 4 cam, 4 valves/cylinder
CLUTCH- 115mm or 140mm twin disc.

To kick things off … some forum posts say (and I quote without understanding what stands there):

Stock: 154#/97# = 97/154 = 62.98% (r/f)
Stock: 154#/97# = 154/97 = 1.5876. (f/r)

Quote from kars19 :

We need LFS physics & Ui/iRacing tracks & netcode/AC graphics/rF modability/beamNG damage

Since you only mention the bare necessities I'd like to add the GT5 Nordschleife to your wishlist. And a ModNation Racer-style track creator with foolproof IRL-GPS-Data-Import-Options. Also, all BMW E30 Models ever made with the possibility to swap a big range of engines into them. Umm … that would be all for the moment.



Easy task for Scawen. Get it ready for the weekend, please.

Yeah, the turbine & electric Jag is awesome!
Too bad they don't build it like it was planned.


Got NTO running like a breeze now, only the vtec thing with torque increase keeps crashing on me, but will keep trying …

Last edited by Mr. Apex, Wed, 1 Feb 2012 20:04.

Nope. Rhama said the thing he wrote increases power at a certain RPM.

P.S.: By the way … not turbine-like at all




And hum, I googled Petter Harmonic and came across this vid:

But I must admit that it is NOT my favoured kind of exhaust note …

I can now tell you have a certain fascination for two-stroke engines. Sorry to tell you this, but the spherical engine is a four-stroke-engine. It is not single-speed, but I dunno about the rev-range. Not sure if it revs all that high. But concerning the KISS-principle:

• 70% less parts than a nowadays 4-stroke engine (can be built in 90 minutes)
  
• 30% lighter than a nowadays 4-stroke engine
  
• 25% more effective
  
• has no crankshafts, connecting rods, cam shafts nor valve timing
  

Well, I just realize it can't have VTEC. Must sound like rubbish, then!



Backontopic: Ever since those mighty mad scientist overlords here moved their discussion to PM I wonder where to find this VTEC mod that increases torque …

If you're going to stray that far offtopic, I'll accept your challenge and post the Hüttlin Kugelmotor:



Now that's the future.

2 strokes stinks! ;-)

If it makes you happy.

What kind of variable valve timing do you like better than VTEC, then?

-> Forbin

Simplicity can be a quality.

Due to it's simplicity, VTEC is very reliable. And well, it wouldn't be economical to run the sharper cams all trough the rev range. The lower revs are for cruising.

And frankly: The increase in torque and power and the sound is what makes for the VTEC experience. If you want a light engine, VTEC is your choice.

Edit: Removed the link due to Rhama's post.

Uhmmmm … 20% is a bit too much IMO.
