Charles,
Good points. As you know the TaG motors were not originally designed to be national championship race packages. They are more suited amatuer competition such as the view the late Tom Argy had, which was a "festival" type regional and national race which was more for fun than the F1 bound ICA/ICA racers. Pick a motor and go drive!

i run an IAME, it it f****in' pulls outta the corner and all the way 'til redline. from about 4500 rpm it feels like a shifter and it just about as fast. my setup is almost the same as a tag but i run an aircooled engine as appossed to some that may be liquid cooled... but the iame engine ROCKS! ive seen the biland run and its not really that fast but i heard it was pretty reliable.Very Happy Laughing Razz [/i]

I'll be trying out a Rotax next year.

Hopefully the weight advantage will help me out. First year in competition karting though, so I need to work on my driving first. Cool

I am running the easykart 125 heavy. I'm very impressed with the package so far. I have over 9 hrs run time including one race day on the air cooled IAME. Havent had any problems. Knock on wood!

IAME, its powerfull, reliable, nationwide arrry of parts, easy to maintain, can do your own engine maintanace, exhaust tuning is easy, on the go carburetor tuning, easy to setup the engine, good power curve from 7500-15500, can rev to 17000 with no trouble, and its clean, self charging, little motor

my 2 cents, the price is great too

all the motors have there good points but i think sone of the biggest deciding factors for some people is the weights of the class for any particular motor.
the tag usa rules are just plain incomplete. all the motors arent fully spec'd as to what stock is
what carb is oem on a sonik comer and ital??
what air box is oem for them? what is the min cc for some of the engines? you couldnt do tech from the i saw

i guaranty the weights will change once the engines are tested fully

so for a guy that weighs 150 he would never want an engine that you would need to weigh in at 390 and the same for the opposite situation


There are a complete set of rules, you just have to know where they are.

I can't speak for others but, if you look on the TAGracing.net site or earlier on Ital's site the carb is very specific "ItalSistem 24mm with butterfly" aka ICA carb.

Thomas and I always agreed that the TAG class would be 3 years to evolve and with it only a year old we have away to go. Most want to have a crystal ball to be able to say what is going to happen, good or bad, right now. Thomas had the ability to get people to slowdown and be calm with the developement. Yes controlled testing will give more answers but not the final ones. To get there it will be real world experience which will only come with time.

Charlie hope to see you at BeaveRun this year.

Cool beans dude.

My son ran one of Brad's demo Bilands a couple times, and loved it. It's sout on the bottom end both from a construction and output sense. These motors had well over 40 hours on them and were no different from a new one in output.

There were some problems with magnetos on the earlier models that have been fixed since. Like all TAG's the clutch is a weakness. Don't know if Tomar is coming to the rescue.

Lap times at OMC were just a tick off the Leopard but that could have been due to chassis (Fittipaldi vrs Intrepid). The Biland won the first TAGUSA Festival by a whisker.

It's a bit pricey, but you aren't likely to need to change pistons for 2-3 years.

Howie - Sometime ago I was asked to do a research on the "TAG" engines. So here some informations I collected. All the engines will run slightly different in different tracks but generally after having driven most of them this what I can see (my opinion):

Biland - Very good bottom end - fast and consistant. To my opinion the initial cost and the maintainace could be a factor as it is a 4T, however do not know yet. It surely can be upfront, especially if run at ideal temp.

Leopard - good bottom, good top. Easy to handle. This is probably the most popular package right now. Only negative to my opinion is the carburator and some details. This package also is a front runner as seen in Vegas.

Sonik - The only engine is the VX 125. similar to the Leopard and can be driven (but does not have to be) very hard. Carburator and Ignition of grat quality. Great performance. As above, can be upfront. Slightly higher price compared to Leopard, but justified once seen side by side.

BM - It is basically a sort of Leopard, made by IAME for their France correspondant. As mentioned is similar to a Leopard. Price is less - I do not know why, but performance is as good.

ITALSISTEM- It is a special type of animal. It is real good but hard to get and to manage as it requires specialized knowledge. I do not know who is handling it here in US.

Vortex RoK - Never driven. I'm sure is up to similar standards - or better - as above, given the name of Vortex. I heard (so it is a second hand concept) that the concept of performance is closer to the Rotax compared to the other ones. I'm sure the importer will have all the infos needed.

Comer - No info on this. Again, given the experience of Comer the engine should be good. I'm sure importer will have related infos.

All the companies involved and all the brands looks like they are getting pretty good in regards to stock of engines and parts. So I'm pretty sure the market it is getting ready. Will also have to see the rules...... Smile

I believe that (as usual) good chassis tuning and good driver will make good results. In some tracks a stronger bottom end will get a package upfront, and viceversa in tracks that are longer and quicker with fast turns a good mid -top end will help. I hope "rulers" will keep weight under control as too much of it will not do good. In Europe average weight for such class is 360 lbs. Wink

With similar weight limits (330-335 lbs), consider that many of these engines are able (if properly driven) to get VERY close to lap times generated by ICA. So they are quite performing - but with an easier management and longer life.

That's maybe a little on the optimistic side. Judging from Stars last year
ICA is about three seconds a lap faster (at both Moran and Infinion).
That's a pretty big gap. It would be less if you dropped the Rotax
weight, but not three seconds a lap less.

It really depends on the drivers. If you have a Stars driver like Glover or Pecorari and give him a TAG at 330 lbs - times will be very close (not better, but close) to ICA.
With an amateur driver on TAG and an expert driver as above on ICA 3 seconds is quite correct.

That was however just meant to indicate that TAG engines are quite performing - as they are definitly not comparable to ICAs for many things. The nicest part of the TAG deal is the great performance with much smaller maintainance and cost.
