What kinda hp
 

Got a 87 lx. here's all the mods. Mass air conv.,76mmair meterTyphoon intake, 65 TB/spacer, 30 lb inj, underdrives, electric fan, smog delete, b cam, and i think i'm probably gonna order some tfs track heat heads(still debatin on which heads but am leaning towards them) Any guesses on what horsepower and torque at the flywheel is gonna be.

RE: What kinda hp
 

Around 265 before the heads

RE: What kinda hp
 

+1

RE: What kinda hp
 

Have full mac long tube, h pipe, mufflers also

RE: What kinda hp
 

gonna buy either the twisted wedge or track heat

RE: What kinda hp
 

235-240rwhp tops. you have basically a stock motor with a couple bolt ons. and those injectors are WAY to big. even after h/c/i those injectors are too big

RE: What kinda hp
 

ok well ford motorsports told me to run 30lb injectors. I would think ford knows what their talkin about but idn

RE: What kinda hp
 

its a hit or miss with them, they said that no aftermarket heads would fit a 86 block and that wasnt true. so really i wouldnt rely on ford racing. but what he said would be good guess, that cam will do little with stock heads, and the rest is just bolt ons, maybe 240 wheel.

RE: What kinda hp
 

235-240rwhp. hell stock 5.0 are 225hp at the flywheel. So what your sayin is with all that i'm gonna do i'm just gonna gain 20hp or so. I personally dont believe that. the intake alone should gain 20 hp. the exhaust oughta gain 15 or so. Heads 30-50 hp. Your calculations dont ad up in my opinion. I aint sayin your wrong but i think it'll be way better than that. When i finish it i'm gonna try and take it straight to the dyno. That will determine it all.

RE: What kinda hp
 

Well if thats true, i can always put a regulator on it. I dont like using them but it serves the purpose. Plus if what ya'll say is true, then i'll have plenty of injector for any other mods i do in the future. i still dont believe 240rwhp. but i'm new in efi, but not in carb. I know there two different worlds.

RE: What kinda hp
 

hey i think your forgettin i AM puttin trickflow heads on it

RE: What kinda hp
 

well a stock mustang dynos at about 191rwhp so i would say that 235-240rwhp isn't that bad with out aftermarket heads. so fo rthe injectors... way over kill. your stock 19s will handle about 275- 300 rwhp and after that 24's will be just fine for about 350rwhp - which is well enough for any mustang with aftermarket HCI

RE: What kinda hp
 

Ok well would it help me if i just drop back down to 24 inj. i already got my 30 lb but can exchange them. If i did that and put the heads on what do you estimate

RE: What kinda hp
 

Well whoever you talked to at Ford.....they didn't know what they were talking about. 30lbs are too big. Unless you decide to run nitrous or an FI setup.....I would buy the 24 lbers......plus your gas mileage will improve.

RE: What kinda hp
 

Maybe they didnt... This guy that i talked to said that with the setup i'm doing i'd need to go with 30lbcause he said i should be close around the 340-350 hp region and you don't wanna run the injectors up to the maximum hp there rated at and thats how he convinced me to buy 30lb inj. otherwise i was gonna run 24's like ya'll are all sayin. Idk but that kinda ticks me off if he was talkin out his @&&

RE: What kinda hp
 

Your stockheads are a big restriction. Just because the part mfg. adverstises a 20 hp gain with their part does not mean your going to get that. Also say you have 5 different bolt ons that claim a hp increase, does not mean your gonna get the total sum of that. All these parts work together to make the power. Matching the right combination of parts is what it's about. It sounds like your going in the right direction here, but I would drop down to the 24lb. injectors if this engine is going to stay normally aspirated.

RE: What kinda hp
 

c/a/i =2hp
underdrive pulleys=1hp
throtle body=3 hp

RE: What kinda hp
 

I am running boost with a small shot of nitrous and only run 24 pounders. I have no problems with them yet, so 24lbs should be plenty for your set up. Chillerman is right, 10hp from one bolt and 10 from another doesn't hardly ever equal 20hp.

RE: What kinda hp
 

well i just thought about something. i already ordered and have the 30lb injectors that i ordered from blue oval industries and i'm sure i aint gonna be able to return them cause they are a electrical part. Now can i buy a regulator and get away with runnin the 30lbers. My plans for next winter is buildin a 347 stroker, bigger cam, etc........

RE: What kinda hp
 

I realize that all bolt ons will not be exactly the horsepower they say everytime. just like trick flow has a ad. with a gt40 intake, e cam, the wedge heads made 78 more hp and 54 ft. lbs more torque than the same engine with stock heads..... I know this doesn't apply to every app. and they probably fine tuned on it for a while. i'm just makin a statement when i'm talkin bout hp on bolt ons.

RE: What kinda hp
 

your intake wont get you 20hp with the stock heads. mustangs dyno about 191rwhp so if you do have 230rwhp thats 40rwhp improvement.

no you cant just crank down the fuel pressure to make your huge injectors work. injectors require a minimum pressure to work properly. if you go too long on the fuel pressure the fuel will not atomize correctly. i want to say 34psi is the lowest you can go without issues but i cant remember off the top of my head. either way, youd have to crank down the fuel pressure to around 20 to get those injectors to work correctly. with the hp your making now, you should run 19# injectors. not untill you have h/c/i will you need 24's. the ford tech was right in one way, you dont want to run an injector at its maximum duty cycle. 80% duty cycle is the max you should run them at. that means for any given amount of time, the injectors should not be open more then 80% of the time (ex. 8ms of spraying time for every 10ms that pass by)

RE: What kinda hp
 

I think the guy is getting frustrated because he is confused. All the numbers that they are giving you are before you install the trick flow track heat heads. After you install them with a good tune you should have 290-300rwhp.

RE: What kinda hp
 

Thanks 94fiveliter. I have'nt installed anything on my motor but i have everything except for the heads which i'll probably order this week sometime. I don't have much choice but to run those injectors cause i already have them and already have the meter thats calibrated for them. I guess it'll run like crap, then i strip it back down and order a rotatin assembly with a much bigger cam. Now you said after i bolt on heads i'll be in the 290-300rwhp!!! Now thats probably close to 320-330 at the flywheel. And i'd be runnin them injectors to their peak.... I dont know. (i'm startin to hate efi)

RE: What kinda hp
 

running a fuel pressure regulator will not help with the fact that your injectors are too friggin big.

you need 24# injectors and nothing bigger.

hell, th 95 cobra R ran 24# injectors on a 351w making 300hp...
The person at ford who told you that youll make 350hp is on drugs

RE: What kinda hp
 

Well i already got the injectors and the meterthat havent been installedand probablynon returnable due to their a electrical part.So now what. I only have enough money to order the heads and the nickel, and dime stuff to finish it up.Maybe they'll make a exception(i hope)

RE: What kinda hp
 

has anybody ever been able to send a set of injectors and meter and they switch you out with what you needed?

RE: What kinda hp
 

i had 30's on my old 347 with a cam and was going to run a 125 shot. when the car was driving around it was loading up all the time because of how big the injectors were. we had to set my intial timing up to 18* just to lean out some.

RE: What kinda hp
 

if you cant return it, get an a/f ratio meter w/adj. fuel pressure
regulator w/gauge and go from there. you might be a little rich
w/stock heads, but if you upgrade you should be able to tune it
just right. if its way rich w/stock heads just use youre 19lb'ers till
you get some bigger mods.

RE: What kinda hp
 

before you buy anything else, do alot of research

RE: What kinda hp
 

I got a H/C/I making 305rwhp with 24# injectors the pressure is set at 30psi for a 12-1 A/F ratio, I think I would have made more power with the 19#ers

RE: What kinda hp
 

ok well i'll try to see if they'll let me exchange them for the smaller injectors and meter. I'm takin ya'lls word on this subject. I'll call em up tommorrow and see what happens. I'll post when i figure out whats up. Thanks for all the help

RE: What kinda hp
 

Ok.will do. Now when i order my trick flow heads(either the tw or the th) will that help with the injectors i got right now and like you said get a a/f gauge and reg. w/ gauge. ya think it'll be ok if they won't take them back?

RE: What kinda hp
 

they will be ok later with lots more mods, but for now stick with the stock ones, you wont be dissapointed

RE: What kinda hp
 

ok thanks

RE: What kinda hp
 

Which trick flow head do yall reccomend? I don't wanna run the o-ringgroove style.I have removed all emmisions. The twisted wedges that'll work for a cam up to .540 lift? or the tw's that'll take a cam with .600 lift or the track heat'?. I gotta bcam but i don't wanna befly cuttin the pistons causeIplan on tearingdown this next winter and strokin it with a bigger cam so i'm kinda tryin to think ahead and not buy heads that won't work later. Any suggestion will be greatly appreciated. Thanks

RE: What kinda hp
 

bump

RE: What kinda hp
 

didnt me and adder just say that wont work??:(

you cant tune 30# injectors to run like 19# injectors by lowering the fuel pressure

RE: What kinda hp
 

Are 100% sure that it won't work or just pretty sure

RE: What kinda hp
 

i would'nt think you could make that inj. drop down to a 19 but maybe a 24?

RE: What kinda hp
 

Well like i figured they wouldn't take the inj. or the meter. So i'm gonna order a set of aluminum heads and hope for the best. If it runs like crap i'll just get another set of injectors and meter. I'm pretty much stuck with em so i'm gonna give it a shot. I thank everybody for puittin your input on this drug out subject.
