Who said Size matters????
« on: April 12, 2009, 08:31:48 PM »
Hi all,

Just thought I would just post here what might be a controversial subject but would like to get people poinst of view.

I have modified my Hong Nor CR1X (or what ever the code is) from a .21 (orginally) to brushless (see work shop section), and now into a 1/10th by fitting a Picco Pixxi .12 engine.

My thoughts for this was so at our local track I can run in the 1/10th class (due to the engine size) and have the larger tank and therefore need less fuel stops.

Also running a larger car I expected better handling but the down side would be the extra weight so slower.

Well the first time out with the car showed the idea would work, however I had the same bell housing on as the .21 which was a 14 tooth. Also the only pipe I had at the time was a JP2 pipe. The car worked but bogged down a lot at bottom to mid range.

The next step was a proper 1/10th pipe (although a .21 manifold), the result was better and a little more drivable. After that I went to a 13 tooth bell housing and now the buggy started to show potential. I went home and found on my 1/10th On Road car a CVEC pipe so thought if anything would bring the car to life that would.

The End result on my local track is outstanding, we have records of all fastest track times from November 08, and the car has knocked off the 1/10th class 10 seconds off the track record. Compared with the 1/8th buggies with this buggy, my record is 42.04 second, last quater the record was 41.38 and this quater is 42.18.

So the end result is I have now got a 1/10th buggy that handles very well and is very competitive against the 1/10th and the 1/8ths, and the great thing is that a tank last 13 minutes so maybe with a large filter and longer fuel pipe I might be able to get it up to the 15 minutes race time which means no refueling in the finals.

I do hope everyone enjoys reading this and I will get some pictures once the sun is out for all to see.

I'm a nice boy really. Honest. 2:)

Can't wait to see it, it's nice to see somebody going against the grain instead of going down the big-bigger-biggest route. Perhaps it could be a new class, the French have FWD buggies perhaps we could have small block 1/8 races.

I'm sure there is a tank size limit when running 1/10th?

Quick update on these great baby block cars, just done the 2 hour endurance race at our track and we had 2 of these on the team.

End result our team own, yes there are fast cars out there but we seemed to be the more reliable and faster lap times event thought the truggies were faster down the straight.

LP - for National champs I think there may be but at club level there is not.

And silly me forgot to still get any pictures or videos done..... I will get some done soon.
