Weber Look A Like Fuel Injection!

[jwd]

Fuel injection is far superior to any carb. for HP and MPG. It is easily tuned for perfect A/F ratios under all loads, that can't be done with a carb. There is a reason that although F.I. is more expensive, carbs. haven't been used in new cars for over 20 years.

That's complete Bull Sh!t. There are many offers up and I'll put up my own. Send me a set to "bolt up" and I'll "easily tune" per the claims and I'll be their biggest proponent. Ford crate 392W. No mods.

What part are you calling B.S. on? I'm not saying this particular vendor's claims are true. I'm only saying that F.I. is far superior to any carb. Do you remember the 70's? With pollutions standards enacted, HP dropped to less than 200, performance cars were gone and gas mileage sucked. F.I. was invented and guess what? We now can go to the dealer and buy a car that has 400-500 HP, gets 25+MPG and now meets even stricter emission standards. Why you ask? BECAUSE OF FUEL INJECTION.

JWD-you are an example of how dangerous a little knowledge can be.According to you multi valve heads,roller cams,scienced out heads,10 cylinders,crank trigger ignitions had nothing to do with the power increase-the magical FI did it all by it's lonesome.

Dean,i just looked at the site again.From what i can tell,YOU supply the manifold.There's more money.Another thing that makes me chuckle:The self tuning computer.Un-huh,like i'm going to spend $6,000 and not be able to tune the system?

And for you FE guys looking at this,you'd need the 10 degree Webber manifold for these TBs(or Webbers) to clear your hood.And then enjoy the fun trying to get filters to clear.

I know this is a old thread, but I have Keith Craft Racing building me a 302/306 with the DynaTek system and will let you know what I think of it next summer. Pending my GT40 is finished by RCR by then.

I may be a relative newcomer to the site but do all of you only care about assasinating the opinions of others or about the cars? Since when does anyone know what is better for someone else? none of you knwo what is a better system for my car any more than I could say I know what is better for your car.

When I first got my cobra and joined this site I was excited becuase it seemed to be about the cobras, regardless of carb versus fuel injected, small block versus big block (although that debate will never end) If no one else will tell you then I will - you all are full of yourselves and just like hearing yourselves spout what you think is incredibly intelligent words of wisdom. when all most of it is CRAP!

It's threads like this that make this site great.

I'm sure your 511 stack injected motor is impressive, looks impressive and makes alot of power, but I would guess it's $6K more than a carbed engine, and although it likely makes more low and mid range torque (HP) than a carbed engine, if you're running less than 58mm throttles bodies, it likely loses power from 5000 rpms up compared to a carbed engine. Not every mechanic on every corner can fix it either, and without some higher priced tools/computer, you can't tune it yourself either.

I see you're having problems as well.

Roush 511 problems

maybe you'd have been better off with a carbed engine? naw. The stacks are worth it.

I believe that is part of the fundamental issue being discussed/brought up. With 20 years of EFI technology behind us, it doesn't make sense why these systems continue to be out of touch for most enthusiasts? I understand supply and demand curves, so I don't need schooling on limited production = higher fixed costs per unit = more $$$ per unit sold to make a profit.

It's just that this particular manufacturer is making some pretty bold claims. And, I might add, at 10X the price that a good, prepped carb would cost. I won't fully pic on them for price...seems like ALL of the stack EFI set-ups get a healthy premium for the cool factor.

They need a guinea pig in So Cal to prove them right? Bring it on! I have over 1,700 posts here and I'm not afraid to write-up full reports on other mods that I have performed in the past (good, bad or indifferent). Check my history to verify. I'd give them an honest test in real world conditions on a motor that is around 470-480HP at the flywheel. That covers 90% of the known Cobra universe (the other 10% being for the real HP junkies). Testimonials sell systems, not print advertising.

Catagorically false.There are even dyno pulls that show a DROP in HP going to FI.
Although,there will be a increase in fuel milage,(but no-where near the 300% claims)there will be NO HP increase over a PROPERLY sized & set-up carb.

And yes,there is a reason there are no more carbs.It's called EMMISSIONS.
