Tillotson Racing is excited to announce the launch of the new Tillotson T4 Series which will debut in the Motorsport Ireland Championship for 2019. The vision for the new category is to provide a cost effective entry into the sport of karting in effect promoting new drivers into the higher levels and increasing the participation numbers in the sport. With this effort, Tillotson is seeking to create the new base of Karting!


The T4 Series will run a Monobrand Tillotson chassis and the latest Tillotson 225RS 4 Stroke engine equipped with a specifically calibrated Tillotson Racing HW carburetor. Only stock chassis / engine components can be used in this competition to control the cost and there will be a dedicated technical fiche for the chassis, engine and carburetor. Drivers can experience the thrill of kart racing while reaching speeds of 100klm using high spec material.


The new 225RS engine developed and produced by Tillotson is designed to offer a fun driving experience with great reliability at a very affordable price. The engine is equipped with a PVL digital rpm limiter to 6,500rpm to maintain long engine life but also offers a wide rpm band for suitable power delivery. Tillotson has designed a new crankcase for this engine to offer a stronger structure and provide a stable production quality.


The carburetor has been specifically calibrated by Tillotson Racing for the 225RS engine. The diaphragm carburetor is more often used in the high level Racing division of Karting but Tillotson is proud to provide a product to offer the best driving experience for the end user - increasing engine performance but also providing ease of use. The main advantage being the ease of adjustability via the adjustment screws compared to the floating chamber fixed jet options existing in the 4 Stroke market.


For this concept to succeed it was necessary to establish a cost effective price to attract new competitors to the sport. The complete package including chassis, engine complete, tyres, chain and sprocket ready to race will retail at a special price of €2,750 plus VAT for 2019 for the Irish market.

And I thought all they did was make carbs…

(James McMahon) #3

Until recently that was the case.

What sort of power will this Tillotson engine produce? 100km/h seems pretty fast compared to what you get from the 206 Karts locally.

It might be a great low cost karting option.

(Don Westlie) #5

Tillotson says about the same as a KT give or take. Which I believe is similar to a WF? Price point is said to be roughly $1k, add oil and go.

Good price point for what it is.

In regards to speed, we did test a WF and 206 at Road America back to back and the WF was about 3-4 MPH faster than the 206 and similar to the KT my Son had been on. So, I would think the comparison Tillotson makes is pretty close.

It’s got my attention! I’m curious how it’ll do.

(Liam Sergeant) #7

That’s pretty promising. The KT Karts here are pretty popular and quite quick.

I suppose the speed thing is track specific more than engine? I barely hit 93 on my track if I get the run right in my Rotax. I can’t imagine the 206 Karts are doing that.

But cost effective karting options have got to be a good thing.
