If you go with an injector hat with mechanical injection good luck getting it to idle low enough to get in gear.

Mechanical inj is not a real "lakable" setup I have a 523" chevy with an inj hat and it runs great but is also a dragboat so like I said it is not real lakable.

INJECTION HAT
I RUN A BIRDCATCHER.NO PROBLEMS.ITS BEEN ON MY LAKE BOAT FOR 2 YEARS NOW.IDLE GETS DOWN TO ABOUT 750RPM ON LOPE.I'VE RAN FROM AVI TO SANDBAR WITH IT NO PROBLEMS.ON OR OFF GAS IS A WIVES TAIL.I CRUISE BETWEEN 3000 AND 4000 RPM.YOU ALSO GOT TO TAKE IN TO EFFECT THE COOL FACTOR.10+ ON COOL FACTOR.

Get the best of both worlds, get the hat that's set up for EFI. Course it'll cost you an arm and a leg :D For cost and simplicity, I'd go with the carbs! http://www.blowerdriveservice.com/ph2.jpg

You better catch that lope just right before you drop that bravo in gear. It could get real expensive if you're already breaking shit at idle. Those drives don't like shifing at fast idles.

Everyone here has good points, that's what I love about this end of the boards. :cool:
I was waiting for some of these guys to jump in and help out, lots of real knowledge right here.
I put my vote in for the injected set up, this was based on a number of things, simplicity being at the top of the list. A lot of people are afraid of mechanical injection because it is alien to them, that's understandable but not necessarily a good reason to not consider it as a viable system.
T-bag uses it to good effect in his drag boat, revndave has had nothing but good luck with it in his application, MAXIMUS agrees. GofastRacer has also loves it in his v drive.
superdave013 is correct in that it can be detrimental to an outdrive if the idle is too high, all of this comes down to setup, just as it does with carbs. craig, like me, would love to have the combination of efi efficiency and the ultra mega cool of the hat.
You can guarantee that there are far more carbed versions out there than injected, probably for a reason, personally, I'm not so sure that reason is justified. :p
No matter what you choose, it is all in the set up and I think all of us would love to hear about your progress regardless of which choice you make.

I usually go to the river but sometimes i just want to get it wet and i,ll shoot over to one of the lakes close to the pad. The engine builder plans to use a primer. its going in a 2600 american offshore.

As far as I'm concerned a supercharger is about the best "flame arrester" you can buy. You pretty much have to blow it off the motor to make fire. Just my .02

GO injection get a Birdcatcher not a Bugcatcher. The Birdcatcher has a better machined surface around the butterflies witch makes it easier to keep at different RPM’s. I have a bug catcher just touch the throttle and it is at red line. eek! If you know how they work they are simple, if you don’t be ready for a learning curve. Unlike carbs, injection has no accelerator pump, so you have to run the idle a little rich to keep it from going lean when you first give it gas. This means if you like to idle around a lot, bring lots of spark plugs with you. :)

You guys crack me up. I love my injector hat too. But I would like to see one pic of a mechanical injection set up that is inside the engine hatch of a 26' cat with a bravo outdrive.
Yeah they are great on v drives and jet boats. Even if you had a #6 drive. But having one in the type of boat this guy's building I don't know about that. Now if it's converted to efi I could see it.

MAXIMUS
08-05-2003, 06:40 AM
Dave I agree with you. Not outdrive friendly. My boat idles from 1000 to 2800 on the surge. I could emagine dropping it in gear! I think it would tear the damn thing off the back of the boat! If not the idling around would be enough to tear out the u joints etc...

So how does mechanical injection work differently then a carb?
I am very familiar with EFI since thats all I have worked on. Carburetors are foreign language to me. I assume that the mechanical injection works similar to electrical but how do you monitor injector pulse width and duty cycles and all that other good stuff with mechanical like you do with efi?

Boozer
08-05-2003, 03:35 PM
Also, with the mechanical how many injectors do you run? Is it like a carburated injection type of deal or does each cylinder get it's own injector?

A/OAL
08-05-2003, 08:04 PM
okay found my pass word :) . what happen I was pretty convinced that injection was the way to go. First of all no COLE I dont want to bring extra spark plugs lol and Superdave youre right I havent seen a 26' cat with a inj. second one of the only reasons I even thought about inj was because the engine builder wanted to use it and after spending all the money for everything so far (building motor from scratch) it would have been cheeper (okay just alittle) to go inj. I guess i'll wait alittle longer and see what the out come is on this site.

I assume that the mechanical injection works similar to electrical but how do you monitor injector pulse width and duty cycles and all that other good stuff with mechanical like you do with efi? It works nothing like EFI. No pulses, just fixed nozzles (above the blower, at the ports or both), a constant flow pump, a barrel valve and a few bypasses. Pretty much in a nut shell it's one step above cave man when you compare it to EFI. But if you race NHRA, IHRA, IHBA or out here the NJBA you can't run EFI so they've gotten pretty good at getting the flow right by using bypass systems that are all controlled off of throttle position and fuel pressure.
In closing in a drag race application I have never seen any other system have better throttle response then an injector hat. But boy will they fowl plugs if you idle them around.

I was planning on racing the new shingle soon but I guess it'll have to be local stuff like Blarney island.
It's been quite a learning curve for me tuning the new EFI setup. You never realize how many parameters an engine runs on until you have the ability to adjust them all yourself, while driving, with a computer in the seat next to you.

Mark [/QB]Turbo imports run under IDRC sanctioning so it's a little bit different. I use to race my car in IDRC events. They are leanient to some things but very strict towards others. Like the fact that you can no longer use street legal slicks in a street class race (one of the reasons I stopped racing).

Ya know I use mine like a regular ski boat & idle through the keys etc... I have never fowled a plug in the last year & a half! I don't know why this has to be. I spent a short time dialing in my set up & I wouldn't trade it for carbs if you paid me! Not sure what the myth is but whatever... :confused:

I'm sure I could have leaned out the idle a bit on mine too. But I had the blower set to kill (35% over) and wanted to have plenty of fuel in there when those butterflys were mashed opened. I did play with it quite a bit and it launched best when it was pretty fat at idle. Was not a big deal as it was pretty much race only. I did run it at the river too but with only a 5 gal fuel tank I wasn't driving around like a ski boat.

Nope, when you slam the throttle open, you are immediately into the main system, the idle part is closed, when you hit 30lbs you're you are on the main pill. You only need it fat enough not to stumble when you ease on the throttle. I see alot of guys that don't like the surge and run them smoothe and don't lean out. :)

Well I don't know about alot of other guys I just know about the set up that I ran. It left much harder when it had some fuel at idle. I still have all the stuff from when Gorr flowed it. At 1,000 rpm the fuel pressure was pretty low. At 7,500 it was around 300psi. It would build blower boost must faster then fuel pressure. That's why I had it fat at idle.
With the barrel set at 30% leak it did idle better. At 40%+ leak I had better time slips.

I had to do just a little more than adjust the barrel valve to make mine a driver. Springs & shims in the bypass, finess the throttle linkage so I didn't get whiplash every time I hit the gas, & very good priming system that was dialed in with home made jets & psi adjustments. Like I said it starts with out any effort & runs like a dream. Nice surge & excellerates ok too! wink

Well that explains why the fat idle, with the low pressure at idle you had to have more volume and depending on how quick the pump built up pressure as rpm came up, you had to have enough volume to compensate. He probably set it up that way to be on the safe side and you wouldn't have to worry about leaning out on different weather conditions since you were using it for a river toy too!..

Anyone know which EFI kit would work good for an outdrive setup with a big blower, say 1071 +?
Superdave. you said $6,000 for EFI kit? is that right? If so, sounds good to me.
so far I haven't had any luck. I have looked at Delco, Holley, etc. I don't want mechanical.
I was looking at the Delco MPI but that tops out at 800 hp. (may not be enough room to grow!) It doesn't look like that was engineered for big blowers.

I was looking at the Delco MPI but that tops out at 800 hp. (may not be enough room to grow!) It doesn't look like that was engineered for big blowers. Talk to Gary Teauge @ GT mairne. I think they are in Upland, CA
Also Chief Engines in Fla has some bad ass EFI systems that go to 1,400 hp.

Here's what you do Bro. I can see your kind of sittin on the fence with this one. Swing by BAE and ask for whoever, then get your ckbook out and write one that will have a lot of zero's on it. Make sure you bring at least a 3/4 ton truck as those 565 hemi's are heavy with the billet heads. Then get your buddy Darrin to help you adapting it to the Bravo drive. No need for anodizing cause it aint goin to be in there long. Make sure the hat and lines are tight and go up river. It should be fine.

Anyone know which EFI kit would work good for an outdrive setup with a big blower, say 1071 +?
Superdave. you said $6,000 for EFI kit? is that right? If so, sounds good to me.
Here's what I got into my "do it yourself EFI system"
************************************************
HALTECH E6K ECU 973.00
TERMINATED HARNESS 128.00
CONNECTOR KIT 66.00
3 BAR MAP SENSOR 96.00
TRIM POT 48.00
TAX 78.66
______
TOTAL 1389.66
*************************************************
Add to this the eight 160 lb injectors that I paid $750 for.
Two throttle bodies that I paid $ 100 / ea for.
One TPS that cost me $ 45.
Aeromotive belt driven fuel pump $ 409.00
Fuel pressure regulator $ 125.00
I had to machine the holes in the intake manifold and weld in the injector bungs and make two fuel rails.

And add to that the weeks I spent learning how to use the fuel maps.

NOW thats what iam talk'n about.get them ball's of the mantel and GO BRO, there's a post,a few back showing that cat with efi,yes GT,perf,set it up.I sold him the blower 14-71 and made an adapter plate for injector and sold him one of my intercoolers.this this efi in this boat works unbelievably awesome. it was 7000.for the EFI, not alot for what he got.yes you can do alot your self,to save a little.but when you get it put together take it to some one like GT to get it going. ok 6000 to get all parts.and still have to beat your head on the wall putting it together. when for an extra 1000.all said'n done.an working idea

Thanks Unchained.
I was looking at the autronic system.
You parts look like about $3,000.
It looks likes its worth the money.
You got a bad-ass project by the way!
