Inliners International Forums General Discussion Hi Performance Induction System for the inlines...

Hi y'all inliners...
From reading some tech Literatures about Induction Systems for the Inline Six Drag Engines,I've seen there are different opinions about the best Induction System for a normally aspirated Inline Six Drag Engine. Some Engine Builders said that three sidedraught Weber assembly be the best one, other said to run two four barrel carbs, other said to use three holleys two barrel carbs or a mechanical fuel injection system, but I'd really like to know what's considered the best one ? I hope y'all experts inliners could give me some answers regarding this issue.Any thoughts would be very appreciated.
Thank you,

All-out racing? My vote is injection. Electronic or mechanical, doesn't matter if it's properly calibrated. Drawbacks? Getting the correct geometry for the fuel spray into the port on a non-crossflow head. That's one reason why carbs are easier to set up and use.

If not useing injection.(injection being #1)
(#2)Webbers would be the best to use Reason being is it is the straights air flow.Or the 3x2 carb setup. I feel my 250 ran better on my intake then it did when i had the dual carb setup. And I feel the reason for this is
That the air flow from carb to head was straighter then the clifford duals. Because the carb sat right over the runners @ straight down to the head/intake port. Hope my 2cents on this helps.}[oooooo]

Ok guys,... but as far as I know, electronic injection system it's best suited for Road Track cars, being mechanical injection the most used in Drag Cars. However I'd like you indicate for me a Mech Fuel Injection Manufacturer specifically for an Inline six Engine, so there's a long time I'm trying to find out one , but until now I've got none reply to that.In the past, Who made that for the inline sixes? Where I can find it ? Just give me some directions about this matter ! Thank you

Maldonado,

Did you ever hear about a guy named Buddy Ingersol? He campaigned a stock-bodied Buick Regal in the 80's with a turbo-EFI v-6. And he stomped everybody until they changed the rules enough to legislate him off the track. He was probably the first to do it successfully, and there are lots of guys now that run EFI and do very well with it.

As far as mechanical injection suppliers, have you talked to Enderle? There is an email address at: http://www.enderlefuel.com
I have great doubts as to ANYBODY offering a bolt-on system for a 6banger. You've got to fabricate most everything except the injectors themselves and the pump.

By the way, have any of you guys seen this webpage? http://www.dragracecanada.com/media/teamprofiles/043.asp
Click on the center photo for an enlarged view. That's an aspirated Deppe engine using EFI running in the low 8's 2 years ago. In a full-bodied car.

Thank you my bud for all. Each and every time I read your posts here in this Forum, make sure that I appreciate your KNOWHOW regarding these engines,...so much. Who's the manufacturer which have made a mechanical fuel injection system for the Kirby's Twin Engine Dragster ? I'd also like to maintain a private conversation with you by email, please email me as soon as you can.Thank you again for the help.

Quite a few Mopar Slant Six racers, use the "Ron's Flying Toilet" mechanical injection, with very good results. http://www.ronsracing.com/
Also there are some articles at http://slantsix.org/articles/articles.htm
on electronic fuel injection. If you go to www.slantsix.org and use the search function, there is a lot of discussion about electronic fuel injection. Search for "Dart270" He has a slant six Dart with Holley Projection, modified with a "megasquirt" home built ECM. This car is a daily driver/road racer/drag racer. http://www.bgsoflex.com/megasquirt.html
