After some financial setbacks and other hurdles (battery, alternator, school, computer,etc..) behind me the car finally made it back to the shop. The first order of business was to replace all the Comptech springs with Comptech's upgraded pieces(I've been told that these are Eibacks-sorry if I miss spelled ). Then new camber kits were installed, which were the entire upper control arm. Lower spindles/ball joints were also replaced(both were bad-especially the drivers side-maybe due to all the wheel hop in its prior life).

Now for the injectors. When we called RC Eng. they suggested we go with the 440cc pieces, after all they were the same price as the 370/310s, if I'm not mistaken. They were ordered but RC shipped the wrong 440s. They were actualy 5mm too long. We were billed for the right ones but received/shipped the wrong ones. We actually received the correct ones yesterday.
In order to accomodate the bigger injectors the fuel rail had to be ground down where the injectors are located. We decided instead of using a dremmel tool to send it out to a machine shop to be drill pressed. The shop made them look very good and all grinding is now uniform.

Before any one says it: "THIS THREAD IS WORTHLESS WITHOUT PICTURES".
They will be taking pictures of the completed work along with the work in progress. So far this is all guinea pig material.

BTW: the injectors look awsome with RCs logo on them and they will be fully visible when comlpete.

We are also going to install a FP gauge(curently on back order-almost 2 weeks)on the the A piller just behind the mirror. My other gauges(boost and A/F are on the steering column) picures of the new and current gauge setup will also be taken.

There is also an oil leak that needs to be fixed. We took off the SC some time ago to replace the plugs and after reinstall I noticed an oil leak.

Once all projects are compete, the car goes to get an alignment and then its final tuning with E-manage. We're curious to find out how these injectors will act with the Comptech FPR. We are hoping to remove the FPR. Our goal is to keep peak fuel pressure below 55-60 if possible. We're hoping the 440s(sounds like a MOPAR ) will help us accomplish that.

The tuner has access to a very sophisticated dyno and the plan is to do 3 runs. 2 back to back and one with perhaps dry ice in the reservoir. If all goes well maybe we'll see 350-365 whp #s
The transmission also needs to cooperate as well.

That is all for now.

 

Sounds like your close, been wondering what happened to your project. Love those old mopar 440's, had a few of those in my time.

anyway, I'd be curious to know how the 440's work in your setup. I'm guessing that it may run a little rich at idle just due to the shear size. I may have gone with the 370's and made them work a little harder, but nonetheless, it's a good mod. Keep us posted on progress.

 

Will the use of a tuned emanage fix the A/F at all rpm's?

 

It should.

Right now the E-manage was set up to max-out the stock 270s. I'm at the shop right now and they were able to install the injectors. Thinjim your right about it being rich, so we don't even want to start the car with fear that the programing would want to max the 440s and cause some engine damage(possible hydro lock, etc..).

The other bit of good news that the gauge will be in tomorow.

So at this point just waiting for the tuning.

 

Sounds great. I really wish there was some injectors that fit without modification. Scalbert never did try and fit the Bosch slim line injector. It closely resembles the size of the stock injector.

 

lets see some 12 sec slips!!

 

It snowed here all day yesterday, I don't think the track is going to open tonight like they were planning on.

 

If the Boschs would fit that would be great. But the actual modification of the fuel rail is a minor job because there is so much material that can be taken off. The real benefit of the 440s is that you can back of the fuel pressure alot and if you ever wanted 750 HP TL/CL....Well there you have it.

 

If all goes well(engine not blowing, tranny not blowing, etc..) high 12s are in the forcast.

 

Hmm the tax return might be purchasing 370s...

 

Anyone know where I can get the Bosch injectors?

 

Oh and as for starting the car up with the new injectors. Turn the car to the "ON" posistion, hook the computer up to the E-Manage, go into the function that allows you to select your new injector size. It should automatically compensate for the new injector size. You enter the stock size, then the new size, and it will compensate for the larger injector.

 

From Bosch?

 

:troutslap

 

Thanks for the info. I'll forward this to the shop.

As for the Bosch injectors I don't know. One thing that I learned that is very impressive is that RC calibrates each injector. The bench test sheet that I looked at showed all 6 injectors within 2 points of each other ex: 440,441,440,442,etc.. OEM versions, like ours for example, might read 270,268,276,279, etc.. That is something RC is famous for. Bosch might be similar, but then again I don't know.

 

Those RC injectors are pricey! Plus the cost to have the rails modified.

Hopefully the Bosch units would fit.

 

Apparently Bosch electronics have not always been the best(at least they were not suggested but discouraged for my application). You might want to even consider getting a set from Ford Motorsports and maybe having them modified. they usually go for $150 a set +/-.
Even though other units, like RCs, are bigger the benefit is that they wont work as hard and as result there will be less chance of failure.

As for the fuel rails you really don't need to have a machine shop do it. If you have a good dremmel tool your good to go.

IMO Since injectors are a very precise and critical part selecting the best is a must even if in this case it cost you. Just hold on to your tax refund just a little longer. :nj:

 

Yeah... i'm just afraid of fucking up the fuel rails, even though they are only like $40 each.

Decisions, decisions... Injectors or wheels....

 

Both the wheels and injectors(SSR Comps, G.Y. GSD-3s, RC ENG.) They all got there long arm in my short pocket...and then some.
