Supercharging Headaches... Before Purchase!

[HGFireHazard]

I've been doing tons and tons of reading forum posts and pages about product reviews and still have questions. At first I thought that 42# injectors would be perfect, based on what people here said, but I've read several posts that have said it's just too much for the mods that I have. For reference I am purchasing a Kirban FPR and the car will be on a Dyno immediately after the S-trim is put on. Has anyone put a S-trim on and purchased a Power Pipe from AFM? What size is the pipe so I know what size to order my MAF. For those of you that didn't use a Power Pipe, what size MAF did you order and did you just need to purchase an install kit to make it fit/install/work after the Supercharger was installed? Finally, on my MAF order form at the bottom it asks if the car has the stock computer, which it does, but it also asks if the vehicle has a chip, and if so what was done to it? Now isn't a dyno tune supposed to be done with a MAF already on it? How am I supposed to tell them what's on the chip if I need the MAF for the tune itself? I've got a massive headache from all this, and if anyone can shed some light on these questions for me I would greatly appreciate it, thanks.

just tell them its a stock computer and then the dyno tuner guy will tune the maf for you.

The powerpipe is 4 inches. When you get it tune, they should be able to tune it with the chip if you have one. You have to tune with the MAF. I dont think you really needed the 42lb injectors, but since you already have them get it tune you'll be alright and they'll give you room to grow. I have a 95 cobra with the stock 24lb injectors and my car runs great.

Your on borrowed time. Tell me it has an FMU. What other fuel mods do you have?

i have an s-trim on my car with a powerpipe and an 80mm maf sensor, that is the best way to go. you'll be fine with those injectors, u could ditch the fmu that comes in the blower kit. your better off having 2 much injector than 2 little, if your tuner knows what he's doing he'll know when 2 add the fuel and when not 2.

Of those who have a custom tune .....................

More run 42's than 36's ... there has to be a reason

The tuner can make 42's work same as 36's!

For a blown combo ... enough and a bit more fuel is a good thing

Lately, lots of peeps on the tuner sites have moved to the Lightning Maf and have had good things to say about it.

I suggest you talk to several Pro Tuners about your maf/inj concerns and see what they have to say

I am running a fmu, with a 190 in tank and a t-rex. As far as mods go not much 70mm bbk throttle body,afm powerpipe and 77mas air meter.

I'm gonna have to throw in with Mr. Penguin Smacker on this one

I don't think you got enough fuel to be safe

I dont see why not, votech makes their kit to work with a stock Gt with 19lb injectors.

If you are buying the Powerpipe from Anderson Ford, then call them as one more speed shop to run your questions by. I can't remember if its Rick or Andy or who the tech guy was that I talked with when doing my HCI this summer, but he was very helpful. They do a bunch of Mustang dyno tuning too, so they have experience.

My Bad

Missed that fact about the fmu not only in your original post
but
when I used the quote as well

Getting blind in my old age

Never the less ... I still prefer suitable size inj's/maf as opposed to the mechanical fmu method of relying upon mega elevated fuel pressures.

I agree. IMHO using an FMU is like putting a bandaid on a severed limb. It might not help as much as you think, lol.

Grady, FWIW, I must have missed the part where he mentioned he had a blower. I kept thinking, why aren't 24's good enough for a stock motor with a throttle body, cai, and maf? lol
