Wiggler- engines are in development, going out to SEMA to do some market intelligence next week.

Mrhorsepower- I know you build your own engines, was just testing the waters.

I can make the same power with a carb than EFI for alot less money. We also currently hold the IHRA World's fastest single 4 barrel record out of my shop @ 6.70 @ 207 with a powerglide trans. NO power adder( NOS , blower ect.) all engine. I do agree EFI is nice and I am doing more and more of it but carbs can still make some AWESOME Horsepower. PM Wannabe with some details on your EFI system.

Then, there is the per unit expense of computer, sensors, throttle body, etc.

Although you may save fuel (in the future), with EFI you have to pay upfront (now)- so the savings are diminished by the time value of money (TVM).

Then there are difficulties diagnosing problems with an EFI engine (for the guy without the laptop and associated hardware/software). And, more sensors and electronics to fail. When the crank sensor fails........you have to be towed. Although the carb runs slightly sub-optimized it may be more reliable.

Pistons are old technology, V8's are old technology, heads with only 2 valves are old technology. Yes fuel injection is ultimately better from a horsepower, fuel efficiency, idle perspective- but- often carbs serve the purpose just fine.....at a reasonable price.

Now back to tunnel rams with carbs/efi.

Wouldnt if the motor had a lot of blowby the evac going to the aircleaner cause detination with the oil getting in the intake charge?
