My Projects


These projects are the ones owned by me OR where I'm the only one doing all the work.

 

I admit I have a love-hate relationship with the whole car tuning scene.  I have met and had to deal with some of the biggest idiots in car tuning and I have met some people who I can truly say are now my friends, as well.  I have only continued these projects because of these good people I have met over the years regardless of all else, and the problems I've encountered, I firmly believe that they have made it all worthwhile. Thank you for your support.


Warning

When getting in to high power builds you should invest the time and money to go with non-stock parts for pistons, rods, and clutch. I think the pistons and rods will be ok for pretty high-horsepower applications once the stress-relief and ceramic-coat is done on them. Anything over a 70% gain will require uprated pistons.

You should have a clear ideia of what you want before setting out on a project.  The best advice I can give to avoid having the sort of problems I've had is that you have to be very careful when you start increasing the performance of your car.

From the number of folks who've done it without problems we know that well-engineered engines such as the FIRE can have their power output doubled or more without problem. I think the amount of attention and care you have to provide increases exponentially as the power increases linearly, though. As you increase power the operational safety margin decreases drastically, and you have to pay more attention to make sure the engine stays in happy operating conditions.

I would also suggest that unless you're comfortable experimenting on your car and dealing with some trial-and-error you should follow as closely as you can in the footsteps of someone who's already done the pioneering. In some cases that may mean sticking with a manufacturer's upgrade plan (i.e. HKS), in other cases it may be just following the footsteps of another forum member. When you set out on your own and push the envelope of the upgrades you've done, as I have (rather than only pushing them 90% and leaving some safety margin), you can get into dangerous territory.

If anyone has any questions or comments I'd be happy to hear them.


My Dyno

I own a custom made engine dyno, it is a brake type dyno with an inertial conversion adapted in 2000. It is originally rated at 250hp using the eddy current brake and 700hp if using the inertial adaptation, the lowest hp measured to date was 4.7hp on a 50cc bike even though it is deemed inacurate below 50hp it was found to be correct. I don't have a chassis dyno so I'm not able to test engines in vehicles, I do ocasionally have access to a chassis dyno at friends place to perform fine tuning on the installed engines.
