Blower On Stock 302

[j0rd4n]

So right now I am just putting on my gt40 intake. I want to put the upgraded injectors in now while it's apart but I've read that this can be a bad idea because they will make it run rich. I don't have the money to buy everything at once but while I was putting on the Intake I was gonna do injectors so I don't have to rip it back apart.

If I have to do it twice then so be it....

Also does anyone know of any more kits that include the fuel pump, injectors, maf etc ?

If I can save a lot of money not piecing it together and buying a full kit then I'll do it that way and leave the injectors stock for now

Before continuing any further I think you need a better understanding about how our engines work and how components need to match each other. You also need to have patience and wait till you have all the pieces together and ready for install. Installing injectors and that intake right now is a big mistake. If you do injectors you have to have a calibrated MAF to go with them or your car will not run correctly. Fuel supports horsepower, it does not create it FYI. It's not hard to remove the upper intake in the future to replace the injectors. You can go ahead (if you can't wait) and install the Explorer intake and retain the stock injectors.

Look in the Mustang classified for some good deals.

...or a tune... or in the case of injectors 42# or larger, you need both if you're planning to drive it to the dyno.

Well I was going to go with the maf as welll, and maybe the throttle body. Basically everything but the blower and pump for now

A larger pump does not alleviate the need for a boost-a-pump any more than a larger fan alleviates the need for a fan controller.

A boost-a-pump is not a pump. It is a voltage controller. It has a rheostat that varies voltage going to the pump from about 12 to 17 volts. What it is good at doing is keeping voltage constant as it powers the fuel pump. If the electrical system gets a draw or a spike then fuel pump pressure and flow stay the same. It regulates vehicle power to the fuel pump and eliminates surges.

I've attached an article that may help explain a bit more:

Noobz no disrespect I know what a BAP is , for some reason I was thinking T rex in line in my head and not thinking of the voltage controller . Either way a 340 will be perfectly fine with no BAP . I ran it with no issue . Many others have as well . No lean conditions , no super heating the fuel .

If you look carefully at the article, having one does not mean the other. As for "a 340 will be perfectly fine with no BAP": That is on "your" electrical system (whatever that may be).

So what tb and maf should I buy with my 42# injectors so that it will run correctly for the time being until I install everything else ? I understand this isn't ideal but wouldn't putting my stock tb back on the gt40 intake defeat the purpose of installing a higher flowing intake?

Your heads are going to be the next bottle-neck. Planning it out will def save you some time and cash.

I doubt you'll find anyone here on Stangnet that'll approve of you running 42# injectors, a calibrated MAF, bigger TB, and an explorer intake for the time being until, at some later date, you get your blower kit. Like others have said you have gotten really good advice but I think you're looking for instant gratification of installing only pieces of a combo that need to be all present together to work correctly.

Go ahead and install the intake if you can't wait, get a larger TB if you want as well. You won't gain much. Just please, for crying out loud, leave the MAF and injectors alone until you're making the power that justifies it.

 

[Noobz347]

You can install that intake and even a larger throttle body if you like. You don't need larger injectors for that. You can pretty much do all of your bolt-on upgrades with the stock injectors until it's time to run the blower.

Depending on what blower kit you're looking at, you may not even need to change the MAF even then.

Putting 42# injectors on a n/a stockish motor is going to either wash down your cylinders and ruin your engine, or at best run like a pig. Look, Ive been working on Mustangs since before you were born. Many people here have built probably anything you could imagine- the advice has been given. I advise you to go back and read what has been given to you until it sinks in, but it is your money and your car.

Just do it once and do it right. Either wait until you install the blower and then do the injectors, MAF, intake, TB, or do what most people do, end paying and installing the same parts multiple times.

Yeah I'm going to leave the maf and injectors alone. I figure taking the intake off again for the injectors isn't too bad. I was just thinking the stock tb would be choking the bigger intake but I'm sure the gains would be next to none anyway so I'm just going to start buying pieces but not installing them

No you're right I'm going to just enjoy it being slow for the time being and piece together everything I need.

42 lb injectors
75 mm maf tuned for 42 lb injectors
75mm throttle body
255 lph fuel pump
And a blower, I have no clue which to get tho

Besides these things all being installed at once I just need a tune then correct ?

The parts list looks pretty good however the 75mm TB should either be a 70mm or 65mm. The Explorer upper intake opening I think is only 65mm unless you port it to match a larger throttle body.

 

[JD1964]

Explorer upper is 68mm. The only TB that fits properly without porting the intake is the 65mm. Also check the TB gasket too. Some are smaller than the TB bore and need to be trimmed.

 

[JD1964]

BTW, blower kits and supporting stuff can run up to 4k. Slapping that on a motor that isnt able to make the best of it is questionable IMO. Build an engine for boost, then boost it. Not the other way around.

I do not agree that you cannot run 42lb injectors on a NA engine such as his. We have been running 80lb injectors on a GT40 engine package in it's NA state prior to boosting. It's all in how you tune it. We used a Moates/Quarterhorse and BE to do this. No biggie.

It is all up to the OP if he can tune it. Sounds like he cannot and relies on a tuner instead. If that is the case then do not run the larger injectors as stated by others.

To put a blanket statement that you cannot run large injectors such as the 42lb injectors is a bit misleading.

It's not can't, it's shouldn't. There is not a good reason for the OP to put them on until he's ready to install the supercharger.

and what exactly is the benefit of running 42# injectors on a stock motor. enlighten me

 

[TurboDude]

I do not recall stating a benefit of running a big injector on a stock engine. But it does achieve the "Just do it once and do it right". And with today's ECU tuning selections that are available, accomplishes it just fine.

In the case of the OP, keeping it stock is the logical procedure until ready to boost. Not everyone can tune on their own or can afford multiple trips to the dyno for such changes and I understand that.
