[Technique] BRC (Superkart)

"Riley Will" said: I am so greatful I found this forum! To be reading pages written by Mr. Thiel and Mr. Overmars is incredible for me. Being in Canada, there is no 2 stroke knowledge which becomes actually designing and building 2 stroke engines. I have read and re-read the 37 pages of posts and always look for more.

My company builds 2 stroke engines for kart racing. Like Mr. Payart of FPE, we build a disk valve twin cylinder 250cc Superkart engine. Just recently we designed and build a 150cc fixed gear engine for American dirt track Karting.

Here are some pictures:

Et joli hommage d'un professionnel à ton forum Marco [Technique] BRC (Superkart) 771973

C'est très beau. Merci pour ces belles images. [Technique] BRC (Superkart) 241515

Good morning Riley,
At [Vous devez être inscrit et connecté pour voir ce lien] I noticed that you offer exhaust pipes indicated # 21 and # 55.
It so happens that Aprilia used those same numbers for two of their most effective pipe designs. Coincidence?
Did you ever try the latest pipes, # 102 or # 106?

a tu une photo plus proche du piston

Le BRC 150cc est magnifique j'en rêvais, ils l'ont fait.
Bravo [Technique] BRC (Superkart) 241515

Dommage d'avoir une cylindrée bâtarde.

heureusement qu'il y a encore le superkart pour faire tourner des 250 cc twin 2t !!

oui, et de fort belle manière qui plus est [Technique] BRC (Superkart) 771973

Frits,

We have tried many pipes. I always come back to the Type 21 and 55. I have not had access to the other designations you mentioned. Would love a try though [Technique] BRC (Superkart) 55116

What is the bore and stroke of the 150cc engine?

Have you ever tried NOX for dragging with a 2stroke?

The 150cc is a 58.0mm bore x 56.7mm stroke. Uses a 110mm connecting rod with 20mm crank pin. Main bearings are NJ205 type. Any other information, just ask:)

Hi Riley, did I see you use a ProX rod in one of your engines.
Its a great forum isnt it [Technique] BRC (Superkart) 241515

Phil,

That was a picture of the first angine where I used a 22mm crank pin. We immediately went away from that and now I use an Italian 110mm rod with 20mm crank pin. We cut the connecting assembly mass by 40%!!! This of course then changed the crankshaft design (balance factor), but in the end 20mm pin is better.

Yes, cant agree with you more, this forum is awesome!!!

Hi Riley, do you know the products sold by TFX engine technology in Canada?

No, I was not aware of TFX. After looking at their website, I think I need to call them! Cylinder pressure really interests me.

Frits and Jan, What sensors would you like on your 2 stroke dyno?

Riley

I have long been in contact with this company and I'm about to buy some of their products. I have sensors PCB Piezotronics to address pressure values exhaust and inlet.

Frits and Jan, What sensors would you like on your 2 stroke dyno?

Exactly what TFX is offering: high-resolution cylinder and crankcase pressures. They also do some coaching!

Frits, you know this material? And if yes, do you use?

Hi Ridley, do mind me asking what engine you use the sensors on.

ridley a écrit:: Frits, you know this material? And if yes, do you use?

A dutch kart-tuner who uses my hard- and software on his dynamic test bench, is quite happy with his TFX-equipment and with the support he gets from them. I have no own testing facilities in Holland but if I did, I would certainly look at TFX. It seems to be real good value for money.

Thank you for your reply, frits. This type of material usually costs a lot, but TFX offers a solution to a very attractive price. I think this is the best way to understand the inner workings of an engine, that is why I am buying this equipment, for development on my engines.
Is that users of this material have a website?

ridley a écrit:: Is that users of this material have a website?

No, he doesn't. Like most tuners I know he says: "I am too busy figuring out engines".
