Redbeards Garage, Road to horsepower.
« on: 15 Jan 23, 08:15 am »
Morning all.
I thought this might be of interest to the CycleKart community as it has more information than anything I have seen so far on building engines to create more power.
We have a limit on the power we can produce. This is something I agree with totally.

Having said that, very little actual data is out there as to what performance tweak does what, and, how that relates to real life drive-ability of a CycleKart or any vehicle. (that I can find - a lot of anecdotal stuff, but few real numbers)

These new videos from Redbeards garage actually put real figures to tweaks tested both on a dyno and on a minibike.

They have interesting results (such as a silencer attached to a header added power!, A billet flywheel with advanced timing reduced power, especially at lower revs, carbs make the biggest difference)

I think these videos would be helpful as, ideally we need to reach a drive-able 10hp limit with the power and torque in a usable range while not blowing the budget or the engine

I will link the first one, the others follow and he has yet (to press) to release more in the series.

Tell me your thoughts please.

Thanks for posting this up Jim - Very interesting and as you say little data out there what does what. I also think the addition of the CVT makes everything a bit more unknown, add gearing differences and it all gets a bit of a giant head scratch, but great to follow someones progress in a controlled way

Totally agree about the TAV30 throwing all sorts of things to think about Andy, and I am doing a lot of that after watching the videos. He did a q+a session live and it seems he has his work cut out with what he is planning on the Dyno in terms of videos. I will be following it with interest

A very interesting new video from Redbeard's garage where he tests a Predator Ghost engine. This engine is becoming very popular in the states, and I can see it possibly coming to our shores soon, a similar thing is offered by Westbank wholesale, although I can't see it being identical and only seems available in 20mm shaft. Watch this space.
It seems to be running a CDI unit limited to 6000RPM. Puts out just shy of 10HP and has most of the torque early, great for cyclekarts and their relatively massive wheels.
It would make a good out of the box engine
Thoughts please

Just be aware Christopher that the shaft on these is 20mm. A TAV30 is 3/4" or 19.05mm so unless you manage to source a 20mm TAV30, please share if you do, it means going down the route of a kart clutch or re sizing the output shaft.
