I have an Aerodyne turbo kit set up for a 2 cylinder and want to convert it to run on the Tcat. The resources that we used for this are now gone, anyone have a directionI could go to get the appropiate parts to do this? ie Carbs, Thunderjets, proper setup?

For what 2-cylinder sled? If it's a series 53 Aerocharger, the turbo is too small for the T-Cat. I've set up a number of T-cats with a turbo.
Have a kit available if interested. What year T-Cat?

It's a 99 Tcat, and yes it's a series 53. We thought it would be usable for the Tcat because they sent tuning tips for the 1000. What kit do you have?

The series 53 model 143/300 is the biggest model in that series. It can only support about 210 hp in a 2-stroke application.
Aerocharger tried for many years to use that turbo on larger than 750 case reed engines with poor results. The turbine housing is very restrictive and adds too much back pressure.

I use older series 60 199/250 Aerochargers on most applications with great results up to 250 hp. They are much more capable. The other alternative is to use a newer series 66 Aerocharger capable of up to 350 hp, but they are very expensive/can't be fixed and no longer available for now anyway. Here's a pic of my 200 mph gokart with 1000 T-Cat engine. I removed the turbo kit that used the series 66 and sold the turbo.

I also use the latest ball bearing auto style turbos with good success on higher hp applications. Of course, they require a separate oil supply system. Here's a pic of a ZR800 CCE I own/built with that type system. Capable of up to 350 hp. For sale $6500.

The T-Cat kits I have are designed for either style turbo with some adaptation. Here's a kit from a 93 T-Cat using a 199/250 turbo. I build all my own components.

So you are adding extra fuel directly through the carbs as opposed to the thunderjet style system? Obviously it works well, I always thought it was a little sketchy as far as accuracy goes.

How did you set up the oiler for the turbo? I would expect a sump and pump, just an electric pump with a regulator, but then a battery also (which is necessary if you run Thunderjets for the electric fuel pump)

I can see how the Aerodyne would be constrictive, we had it on a ZR700 and it was passable, but looking at the housing it just looks small.

PM'd you.

Wow, that would be a fun setup... What would a turbo cost for a tcat?

Around $5-6K new. $2-4K used.

Up to 350 hp at 16 psi boost on race fuel with a stock engine.

How about on pump gas... How trail friendly and reliable is something like that?

There's more complexity of course. You must be a knowledgeable tuner and expect some added maintenance. But, it's just as friendly as any other big hp setup. In fact, it gets better fuel economy than most big bore kits because you aren't using the power all the time and the porting is stock. Cruising at high part throttle at higher speeds can be problemsome due to the tendancy to lean out with boost forcing extra air under the carb slides and needles set lean for good response and fuel economy. EGTs are a must for monitoring/warning of these conditions. Cold starting is much easier than most big bores. Due to the availability of 93 octane, or lower, pump fuel, you must keep boost to a lower level, around 5-7 psi. This produces about 35-50% more than stock hp. But, it's easily adjusted for big hp with race fuel. You drive a turbo sled differently than a naturally aspirated one. You must anticipate the need for using the throttle and allow a little more time for it. A small amount of boost lag is usually there from a dead stop drag race. But, there are many ways to reduce/eliminate that with good clutching and carburetion setup. Turbo sleds are becoming much more common nowadays due to the need for smaller engines for the increased fuel economy and still retain more power when needed. It's even possible to totally eliminate any turbo boost by disconnecting the wastegate if low octane fuel must be used. I've been trail riding turbo sleds since 89.

do you happen to have any thundercat kits on hand for the 99 to 02 chassis? Price for the entire package?

PM'd you.
