turbo install, For the 3.0 Options

[iamchappy]

I am at this time considering a turbo install on my 3.0 engine, I would be using the guts of a used bae turbo kit for the 911sc. I know that I will have to do a lot of fabricating and loose some useable storage space in the trunk. I have enough support from those who have had the turbo kit installed on there cars for 20 years, and have sorted all the little problems out.
I now have to justify the need for 300hp, when my car runs great as is, but lacks a little heart pounding thrill.
I like the idea of turbocharging as it is all external, biggest hp gains without internal modifications, and I have the capabilites of fabricating the plumbling. Plus it can be done for less than a pair of carbs.
Someone twist my arm, it's a turbo or it's a new paint job for the car. (IMG:style_emoticons/default/confused24.gif)

The guys who run the bae kits swear by them, I have been talking to a guy who has had one on his 78 SC for 20 years. I think if one rigged a pressure sensor to trigger the cold start valve for fuel enrichment, used an intercooler may be ventilated by electric radiator fans, run the turbo up the right side of the trunk maybe even cutting it open and create a boxed area to bring the turbo closer to the intake to lessen the lag, blah blah blah blah, I think it could be done.

Hey, I bought a turbo 'cause I'm hooked on them -- I ain't gonna say "don't do it" (IMG:style_emoticons/default/laugh.gif). I'm just saying that attention has to be paid.... I'm sure you already knwo that tho...

On a cool MN night 12 lbs of boost! You Go Boy! I was just in the cities for Tues & Wed. I was thinkin I should have dropped you a note.

Be a plumber and go turbo, paint can wait speed can't

I fell the need, the need for speed.

pressure sensor to trigger the cold start valve for fuel enrichment,

IMHO, that is a half-assed way to do it and is a sure way to blow you motor in no time flat.....

Aux. fuel injector moduals are available for a few hundred or use an aftermarket FI such as Megasquirt if you are trying to do this on a budget......

[iamchappy]

I think if I decide to do it, I will stick with the stock proven to be reliable, bae kit running 8-9lbs. Change the mechanical advance in the dizzy and see how it runs.
I maybe satisfied with the performance gains at 8-9lbs., if not then I would make the changes. I do wish to keep my engine in one piece.

Let me know next time you come down to the cities. I may have to make a run up to Lutsen to drop off some stuff next month if i'm up in Duluth I will drop you a note.

That would explain how he has run his engine like that for 20 years.

He is actually using an additional cold start valve piped into the intake system, with a hobbs N.O. pressure switch set to close at around 5 psig and activate the injector.

I happen to personally know someone who is doing the same thinmg to his 911SC with a BAE turbo system (IMG:style_emoticons/default/headbang.gif)

Here's a pic of "my friend's" 911 SC with the turbo installed. 5 psi to start with, gradually creaping up to a target of around 9 psi with intercooler and supplimental fuel injection, should top out at around 320 very driveable hp.

Sammy, been a while. Come back again soon, man!

Sammy,

What have you seen for intercoolers? I'm guessing that when your friend goes to intercool it, he/she'll have to switch to the tea-tray turbo tail, yes? If not, I'd like to hear more about it -- location/etc.

Hey Sammy !!!! Welcome back(?) (IMG:style_emoticons/default/smile.gif)

I was not knocking the BAE kit, I was referring to Chappy "rigging" a sensor to the stock cold start valve...I know it has been done successfully, but if not careful, it can be a costly.....see you at Dunkels (IMG:style_emoticons/default/beer3.gif)

Hi guys. Thanks for the welcome.
i agree that using a cold start injector in the stock location might be a gamble, he's using an injector that's located in the turbo compressor discharge piping so it has time to atomize before going through the throttle body.
it would only be injecting diring periods of boost so the air vewlocities should be adequate to prevent pooling and the air temps would also be high, aiding atomization. As long as all 6 cylinders get the same amount of additional fuel there isn't a problem. If the distribution of fuel is not even it could burn a piston.

I... I mean my "friend" is planning to use a good air/fuel ratio meter to monitor things as he creeps up on the boost. The car already has a turbo whale tail on it so room for an intercooler shouldn't be a problem.

5 psi boost should be good for around 70 additional horsepower which is plenty, for at least a week or two until it gets boring. That's the problem with boost, too much is not enough.

BTW, I prolly won't make dunkel's this year. I'm 23 days into a 35 day, $17 million project with my name on it. I'm putting in 14 hours a day 7 a week so there's not much time for anything else right now, i'll sleep when I'm dead.

I might be able to weasel out for an hour or two but it aint gonna be easy.

Here's some pics of what I'm buried in:

That yellow crane is rated at 275 ton lifting capacity and is over 200 feet tall.
here's one of a 17,000 horsepower gas expander (power end of a gas turbine) that we are installing:

That better be ball bearing! Or else it will take forever to spool up!!!! (IMG:style_emoticons/default/laugh.gif)

Thats big, cool, (IMG:style_emoticons/default/idea.gif)

I agree with Mueller. DO the turbo, and get a real FI that you can tune with a laptop and a wideband sensor. You need the Fuel/Air ratios to be right or else you are going to have a pile of bits on your hands.

MS is pretty easy and cheap, or there are plenty of aftermarket thingos if you don't want to get into the DIY end of it.

Ok, I went and sprung (IMG:style_emoticons/default/boldblue.gif) for it. The bae turbo kit will be on it's way soon. The paint will have to wait a little longer, now comes the fun part figuring out the best place to put it, and how. I always wanted to have a 914 turbo Porsche. Yeee Haaa. I will post as I progress through it as a record to all who may wish to do it in the future.
