efi

 

The thing that I thought everyone would have brought up was forced induction. EFI ushered in a whole new age of FI systems when it came out in the 80s. John Lingenfelter even said the biggest advantage of EFI was how turbo/blower friendly it was compared to carbs.

 

I have a quick question for you efi guys. How do you guys throttle stops when you have efi?

 

How do you guys run throttle stops. (sorry forgot a word)

 

I don't get what you mean.........the throttle stop is built in to the throttle body.

 

In bracket racing they use throttle stops whis is a plate under the carb that can close restricting air/feul to the engine. This allows the race car driver to dial in the E.T.

 

I've never heard of the fuel injection equivalent of what sounds like a restrictor plate to me.

 

Its not realy a restrictor plate because its not constant. It is adjustable from the cockpit while the driver is running down the track. Some guys will use it after they launch the car, others use it at the end of the track to slow the car down so they don't run over their E.T. I'm a little confused because fi is not used in pro stock only sportsman which is braket racing. So why isn't there a product to help you run consitent E.T.'s like they have for carbs?

 

I don't know, the guys I know who bracket race get close to their dials without some sort of cockpit limiter. It doesn't seem necessary, but I guess it is one way to hit your dial.

 

do you fi guys run things like transbrakes, reverse manual valvebodies, solenoid shifters, air shifters, vaccum pumps, dry sump oiling systems, delay boxes, ect.?

 

I don't know about the dry sump oiling system or the delay box, but yes on everything else.

 

I'll add yes to the dry sump oiling because I've seen kits for sale, not to mention the new Z06 has it from the factory.

 

Why the hell would the method of adding fuel in the engine make a difference as to whether or not people used transbrakes and reverse manual valvebodies?

 

is it seems to me that the fi cars are usually more stock then the carb cars. I don't think I've ever seen a bare bones efi race car, but I'm shure theres got to be one out there.

 

Tons of guys with automatics run transbakes, and many people who convert from a 4L60E to a TH400 will use a reverse manual valvebody. I don't know how many "gutted" cars with fuel injection are out there, but I remember people bitching at an outlaw event that the winner was gutted and the runner up was full weight.
