FI works better

fredjohnston · 09-27-2007, 12:55 PM

Tommy you forgot the:

Aerodynamics
Torque arm Suspension (on F-bodies)
Weight distribution
Rollererized engine components
Evolution of technology will benefit the FI cars more than a car that's been beat on for 40 years...
One is a steel head and steel manifold big block..one is an aluminum head aluminum manifold small block.

Oh wait..they are advantages for the FI car and you seemed to have left them out

FI works better? Better than what? Is that why every N.A. comp car that has tried it has switched back to carbs? Or why Pro Stock has not switched? The carb will cool the fuel making more power. The FI fires the fuel in right at the port not on top of the manifold letting it cool. I will say after you have spent hours testing on a dyno and on the track the FI car is simpler to make a change with the laptop than disassemble the carb. But You have to have done the testing to know what change to make. And yes I have raced both and won with both.

1969 cougar 428...3,750#...best 60 foot 1.45 [footbrake 3,000] . Fi Firebird -Camaro normal 60 ft.1.35 and better. Not a horsepower issue,a suspension -wheel base one. Bart

Fred I will agree on the aero and the roller engine is a better deal. But is it better then 46" and 100 cfm?
PS I dont think Private Ryan's A/FIA Could hang with Fred Henson's A/SA 9.80's Pretty stout! All of the records are with in .030 A/FIA A/SA B/FIA C/SA and C/FIA E/FIA The only one that is faster is Private Ryan the old school cars are faster in C and E. So really are they better?

Tommy Gaynor · 09-27-2007, 01:23 PM

Hey Let me help you all out! Go to the classified section and buy my car! I will show you all the tricks that all of us FI guys have like the control, alt, F7 tune up. It helped Mark Maul with the US Nationals in 06! Jim Waldo has switched and never looked back!

That only because they are all 1.35 + under... With the .2 off the index it'll be interesting to see how fast they (and the Ford 428s for that matter) can really go.

Why don't you bring up the Cam Specs??? That 390 int 401 lift cam in that 396 I'm sure is at a disatvantage. The intake on the 396 is also suspect, compared to an intake that just has to worry about charging Air into a MPI lower intake. Maybe not all FI cars have an avantage, but many of them have.Just look at the SS qualifying for that Atco Points race.

Todd - FI is not legal in Pro Stock. Comparing comp engines and the engineering intake tracts they can construct to a stock eliminator engine limited to cylinder head technology that is 30 years old is ludicrous. 600 cfm throttle body is dry air, equivalent to 880 cfm carburetor for ability to pass enough air to mix with the fuel that can be programmed for volume and duration in accordance with valve action and forced into the cylinder at 40+ psi. No comparison. Not to mention that the LS1 heads flow better than the 396-325 heads and the intake tract is shorter.

Not even apples and oranges; more like rocks and monkeys.

oh yay...

i get to run a 350 cid caddy which weighs 500lbs less and has a 3 speed tranny and a 500cfm throttle body...

seems overmatched against my 283, 4470lbs, 2speed trans and 435 cfm 4gc

oh what a great enhancement...

dear bob, please post your race schedule so i can hide out
