I am wanting to build at Street Port 12A for SCCA club racing. The class is Super Touring Under (STU).

Under the STU rule set 12A and 13B engines are allowed to be street ported. I want a race port for intake and exhaust...does not need to be streetable or even close to streetable.

 

Pineapple Racing's porting templates are really nice.

 

Thanks. I sent them an eMail the other day but they have not responded. I will give them a call

 

PM me if you can't get a response, I can go there in person and make sure you get what you need.

They're slammed with engines, and their parts department usually takes the back burner.

But it's a small shop with a high demand for their proruct.

 

Are you going to use a Carb ? or Fuel Inj ?

 

Carb. I am waiting on a ruling from the SCCA to find out exactly what I will be allowed to run. From what I have been told unoffically it will be an IDA

 

Thats the one thing i do not like about scca. . . they are too strict on rules and regs. I prefer sanctioning bodies like nasa and recently FARA in south florida where there rules are more open and flexible as to classes and you have the oportunity to be creative into building what you want and not having to go into an open class or spend more money to do a GT car when all you want to do for example is run fuel inj in a certain class.

When is the scca going to learn the carburetors are for historic racing (add NASCAR to that)

 

Well actually the SCCA does allow FI if it was originally installed on the engine. Since STU is an engine swap class the induction system is tied to the engine that is being installed. In my case I want to run a 12A which did not come with FI. I want to run this engine for a number or reasons starting with the fact that I have 2 good ones and it gets a lighter min weight in the class at 2450. I have the option of running a street port 13B or a stock port Renesis at 2600lbs. Both of those engines would have FI. As would any of the Mazda piston engines I could swap in as well. This would include factory Turbo and NA engines up to 3.0L with 6 cylinders or less.

Personally I do not see the requirement to run a carb as being a penalty. A Weber is extremely tunable and easy to adjust. We have 6 E Production cars in town that all run IDA's and there is a wealth of information for this setup. If you have access to an air density gauge and a pyrometer you have all the information you need.

Using SCCA Production as an example, a car builder has the option of using carbs or FI on most of the engines. In some cases the carbs work better and are usually cheaper. In others - like the Acura Integra and Miata - FI is a better choice.

Several years ago I looked at NASA and even joined for a year. I liked the concept of the PT rules. I also liked that the National Championship event is all inclusive. However, I have noticed that the PT weight calculators became more and more complicated over the years. Last time I looked they were impossible to decypher. While I was a member the PT rule set was never up to date. Also there are only 2-3 NASA events in my area each year and the level of competition is not better than what I have access to in the SCCA.
