Need more fuel rail/vacuum help please!

I'd bet this had an impact on your dyno numbers after the stroker install? I'd be curious to get the old girl back on the dyno and give it another spin - I'd bet your numbers are better.

Me, too! How much is a typical dyno run? It’s been a minute since my first and only and it was incorporated into one bill with the engine rebuild, etc. So not sure how much they “should” be? Make sure I’m not getting screwed on price ;-)

 

[joemomma]

Probably depends a lot on the area, and how busy they are. Honestly I'm not really sure - with no tuning and just 2-3 pulls, I wouldn't expect more than a couple hundo?

 

[ttocs]

if your getting a tune you can expect to pay some $$$. How ever I know that there are a couple of car shows here in my shitty little town that either have a dyno at a shop or bring a dyno and let people make runs just to see what the power is, who has the most, ect. I have seen those go for $25-50 at one show at a local technical school that has an automotive program.

At FTK (Full Throttle Kustomz) in Fillmore, CA just finishing up.

($400) to reset the timing; pull the chip, run it open loop, step test , set & button it all back up.

With the OE FPR, it was running 15% too lean across the board (1.0 @ WOT for example)
370 hp at flywheel
474 ft lbs @ flywheel

277 RWHP
355 torque

don't you have 24 lb injectors already? They should be able to support that from what I have read.

Your running a 347? If so those numbers are really low. Id step up to ain of 42# and a pump that can handle them.

Yes, 2

24lb injectors

Would that affect my ability to pass the Smog Test? And what kind of impact on mpg??

 

[ttocs]

I think you would need to get a bigger fpr which is where you ran into problems with inspection not being stock wasn't it? I doubt they would notice the different injectors but the fpr would stick out for sure.

Not necessarily. In a nut shell, really simplified, your fuel pressure and injectors together determine your fuel flow. Blah blah blah, I'd imagine a set of FRPP injectors with a stock FPR would be plenty happy. A new tune would once again be needed to get things in check with bigger injectors, but I agree that 277RWHP seems really low for a 347.

What is the rest of the combo?

BBK 75mm throttle body;CAI (fenderwell); Accel 24# injectors; AFR 165 heads; Crane E-cam; Scat rotating assembly; stock FPR; stock fuel pump (as far as I know, anyway)

 

[Daryl]

I’ll contact my tuner and compare what he says and confirm the 42# is his recommendation as well. Might be tough finding a direct source to buy from that’ll ship them to CA.
Any suggestions there?? Anyone??

Re: the low numbers… maybe all the smog stuff on the car limits that? IDK

 

[ttocs]

I don't think the injectors themselves are illegal to ship to ca, just illegal to install. A stock 302 with the heads/cam should be able to do those numbers.

I'm gonna throw a few things at ya.
I don't see an intake listed, are you running the stock intake? If your running stock intake I understand the low numbers. AGR 165s are a good head but to small for a 347 to take advantage of the extra cubes. They will also hold ya back.
I know your in Cali and limited by the communists with that said it's going to be hard to take full advantage of your build.
Consider a really well built efficient motor should hit 1.1 to 1.2hp per cubic inch. With the communist limits you have I don't think that's possible. That said I would think 1hp per cubic inch could be had. It will take some more tweaking and time but I think it's doable.
The tune you posted was this with the lean condition throughout? With what you've posted so far I'm assuming yes. The stock fuel pump would be the first thing I replaced.
As far as going to a 42# injectors your tuner has already told you so. I'm assuming the he has the duty cycle maxed or close to it on your 24s.
The choice as to what you want to do depends on your end goal and money.
Are you satisfied with what you have or do you want a bit more?

Unfortunately, in CA the smog test shops are mandated to ensure the fuel system is untouched OR has CARB stamps/numbers/stickers that allow aftermarket parts, like my fenderwell CAI.

I guess I’m stuck with what I have. I may have a way to get some 42lb injectors to me tho. ;-)

Then there’s the matter of the proper fuel pump for my set up & costs (including labor) to do all

 

[duh09]

Swapping injectors and pump can be done pretty easily if you wanted to dig into it. Dropping the tank is annoying when they’ve got a good bit of fuel in them, but not hard at all. Injectors is easy work.

I am curious what alls involved in their visual inspection. I wouldn’t think they would have the specific colors laid out but I could be wrong.

 

[ttocs]

you just need to find you one of those guys that does not let the government tell them what to do and is willing to buy them and ship them to you. That should be easy to do here. The way they are hidden under the intake I doubt they check the colors to see if you have the proper size injectors in there.

Injectors and fuel pump shouldn’t be a problem for the reasons you stated. It’s the darn FPR

Injectors I’d have a go at; fuel pump most likely too after I YouTube it and see what’s involved and if my skill set can do it!
