N/A 2v guys

[scott5]

Well lately alot of people are coming onto here and wanting to make big numbers out of 2vs n/a. And i never could help cause i dont know too much about these motors, so i went and started doing some reading when i found an article in the new Mustangs and fast fords magazine. It explains how to get 435 hp n/a.. It was a pretty good read and a great starting point for you guys looking to stay n/a and still get power out of your 2v's. I just figured i would throw this out there to help some friends out:goodidea:

i read this article too....very nice article an i was pretty damn impressed with the numbers for having no bolt ons at all except kooks lt headers...makes me re think the numbers people said i would make

You need to get that thing on a dyno!

[Killercanary]

Did you see the RPM's at which it made its peak HP and TQ at though? It'd be good for the track but I would go another route for a car that sees street duty.

yea i noticed that too, 7k rpms is pretty high to be shifting, as i would think on these motors

[PunisherStang]

true the real power was made at 7k but the power was pretty good also up to 7k....an scott i know i need to get my machine to a dyno...just a few odds an ends i wanna add to get the most out of the dyno tune b4 i go an waste all that dyno money

If you just want your car dyno'd to see what it does, i know someone who you can do that with for pretty cheap, just to get you an idea

[PunisherStang]

pm me some details scott....i always heard wait til you are complete with your car to get a dyno tune...i mean obviously if you get a turbo etc get one right away but im just saying in general.


i would def be interested in seein what it makes scott

[blkp42e]

you dont need to get tuned to use a dyno

[PunisherStang]

oh i know...i was on the dyno when i had full bolt ons.

[blkp42e]

what's acctually done to that thing again?

[PunisherStang]

what's acctually done to that thing again?


block bored an honed .30 over...forged pistons rods, ported heads w/new valves, stg2 cams,valve springs,full bolt ons, full exhaust,4.10s,sct2 programmer w/custom tune by 383taman.

[2001GTTT]

what did it make with full bolt-ons? and what kind of parts were they?

[PunisherStang]

well i went to the beatest dyno ever bc my buddy got us a deal there...speed nation.....it made 264hp an 288lbs tq. an i think im suppose to add 20 percent or something some people told me cuz it was a mustang dynometer or something i cant remember an when you say what kind of parts do you mean bolt ons or the motor parts?

like the brand of all the parts you used. I thought stock gt's made 302 tq?

[PunisherStang]

like the brand of all the parts you used. I thought stock gt's made 302 tq?
ya they do 260hp an 302tq but i dunno could someone clarify for me on speed nation? i was told the dyno is off an you add .20 percent to find the real dyno numbers.

the parts were mac cai, accufab 70mm tb an plenium, 1.5in intake spacer,bbk u/d pullies,frpp shorty headers, magnaflow catted xpipe,slp 1 catback, 4.10s,sct2 canned tune.

my exhaust is lts o/r x an still the slp1 now an i have of course the motor built an a custom tune instead of a sent canned tune.

[PunisherStang]

that 264 an 288 is to the wheels

[scott5]

yea i was getting ready to say that.. those numbers are at fly wheel

[SonofaBish]

Mustangs make over 200 flywheel horsepower?


.... hmm.... news to me....


:D

[PunisherStang]

with the bolt on numbers what would my numbers be for the crank? i know its diffrent now but im saying back then what would my crank numbers be

hehehe.. stock camaro in 95 made 300:eek:

oh come on now bish

[SonofaBish]

hp/.85 will give you the flywheel horsepower... that's using 15% drivetrain loss... so that'll be +/- a little

[PunisherStang]

319hp an 339tq to the fly? im so confused....ok so i made the 264hp with just bolt ons...now i have heads cams an full motor w/diffrent exhaust and everyone on every forum says when i dyno ill be in the 320-330 range to the wheels at the most....how is this?

[scott5]

now do that same thing to the 320 to 300 as you did to your first one

[SonofaBish]

264/.85 = 310.59
288/.85 = 338.82

320rwhp equates to 376.47 fhp

so, i don't know fords so much, but you don't think that 60rwhp for cams/heads isn't very good? built motor may mean something, and may not.... did you change the compression ratio?

[PunisherStang]

damn with 320 calculated it would be 376 an with 300 calculated it would be 352.........those are pretty good numbers....would my torque numbers be pretty wicked then?

[SonofaBish]

where is the 300 coming from? i don't remember it being mentioned?

As far as your torque, that all depends on what those cams were made to do. Depending on valve events, they could make some mean torque nubmers and leave a little hp on the table, or they might rev well and make good hp, but the tq curve isn't as nice...

only way to know is to get a dyno graph

[blkp42e]

a mustang dyno gives true numbers because it puts a load on the rollers to simulate the friction between the weight of your car and the road.

what do you consider full bolt on's?

an intake manifold is a bolt on and you didnt mention one of those.

true, but the newer dyno jets are able to do the same thing....

The dynojet that my car was tuned on actually loaded the car a little too much... The car spooled the turbos on the dyno quicker than on the street, and therefore my tune is way to rich right before boost hits (on the street)... but that's a whole different story... just saying that apparently DynoJet has addressed this

at the time i did the dyno they only had the bullit intake manifold out on the market for the 2vs.

where is the 300 coming from? i don't remember it being mentioned?

the 300-320 number is coming from people on about 4 forums...i posted threads on the 4 forums i belong to an asked what they think i will make an the majority said 300-320-330hp..thats where the number came from.


so, i don't know fords so much, but you don't think that 60rwhp for cams/heads isn't very good? built motor may mean something, and may not.... did you change the compression ratio?
oh i think thats very good, i was just confused on the dynoing calculations, etc....yes the compression ratio is change to a little higher than 10:5:1.
the cams are crower stg 2s

i dunno what stock 2v's have for CR, but the higher CR will help make a few more ponies, as well as help w/ efficiency...

[PunisherStang]

i believe its 9 to something for the stock compression

[SonofaBish]

i believe its 9 to something for the stock compression
silly Ford owners... my engine has a CR of 9.0:1 and makes 360rwhp WITHOUT boost! lol... so buy it!

Good luck man... i'm sure you're car is running just fine. Also remember, when you go to the dyno, there are all kinds of factors in the weather that day that can skew your results... so don't get all worked up if you go on a humid 90* day and don't make crazy good numbers

[PunisherStang]

oh i def understand the weather factors completely...a shame tho mother nature has to ruin fun....but im sure it will turn out great when i go.

[PunisherStang]

what dyno did you go to bish?

[SonofaBish]

what dyno did you go to bish?

AWD dyno at Wyotech....

That dyno reads very low (I think its out of business, so I suppose you could say "read")

My friend's stock LS2 GTO put down, iirc, 312rwhp. A friend's stage 2 SRT4 put down something like 240whp. I had nothing 2wd to dyno at the time, but would have been heart broken with the numbers I'm sure.

So if you take that as your standard for that dyno, 312rwhp/.78 = 400 crank hp. Using the same math 264rwhp/.78 = 338.5 crank hp.

[Troll]

Scott... thanks for the info. In my stupid opinion, any time you get over 1hp per ci at the wheels n/a, you have to spin the piss out of it and you're going to lose low-end and streetability. :innocent:

Punisher... please post that original dyno graph. If you got 264hp with bolt-ons on the stock motor (on a low-reading dyno) you got some kinda freak or you transposed the last two numbers. I'm not trying to break your balls, but there are about 3 million bolt-on 2V 4.6 dyno graphs flying around the internet and most dyno ~245hp / ~290tq max. I had two 2V PI 4.6s with cai, tb, upper plenum, underdrives, o/r mid-pipe, catback and they were both 240-250hp and 285-290tq. :rolleyes:

Now, with the heads, cams and longtubes, I think you should be about 300-320hp at the wheels. The built bottom doesn't really make hp. If it's 10/20/30/40 over, you'll pick up some cubic inches and maybe 5hp. Those forged bits don't really add more hp, they just make it stronger so you can throw some boost at it later. :goodidea:

Look for the next dyno day at Big Shot dyno or Hybrid. They're both not more than about an hour away from you and it's fairly cheap. :thmbsup:

[PunisherStang]

troll ill look through my big book of recipes an stuff an find the dyno graph an take a pic of it an post it...my car is .30 over.....maybe i have a factory freak lol jk. i dunno

bo- why are you using .78 for the calculation? this is the part where i get so confused on how you guys come up with the number to divide by etc.

[SonofaBish]

Scott... thanks for the info. In my stupid opinion, any time you get over 1hp per ci at the wheels n/a, you have to spin the piss out of it and you're going to lose low-end and streetability. :innocent:


Are you talking about only 2V cars?? I hope so, b/c thats crazy... before i built the motor in my car, it made 398/402 with just a cam/different factory head, and 7 crushed piston skirts... on 346 c.i.

The built bottom doesn't really make hp. If it's 10/20/30/40 over, you'll pick up some cubic inches and maybe 5hp. Those forged bits don't really add more hp, they just make it stronger so you can throw some boost at it later.
Agreed... a few horses for the CR, a few for the cubes, and maybe a few if the forged internals are lighter...




bo- why are you using .78 for the calculation? this is the part where i get so confused on how you guys come up with the number to divide by etc.

312/400 = .78 .... He's using that number because his friend's LS2 GTO, which is factory rated at 400hp, made 312rwhp on the dyno... so he's saying that dyno reads a little bit low, since its extremely unlikely that the GTO lost 22% through the drivetrain. So he's saying that you should use .78 for that dyno, instead of .85 - which could possibly be a little bit off yet, b/c LSx motors are usually a little underrated the same way the 03/04 cobras were - but i don't keep up on the Goat's, so i can't be positive on that...

[blkp42e]

troll ill look through my big book of recipes an stuff an find the dyno graph an take a pic of it an post it...


you have a book of recipes for your car?!?!?!

:D

[PunisherStang]

Ya i have every recipe for everything i bought or was done to the car. its good to keep all recipes etc i think....why does noone else save recipes?

[blkp42e]

i have a good recipe for chicken.

and all the receipts for my car too!

[Steve-0]

i have a good recipe for chicken.

and all the receipts for my car too!


:rofl: made me chuckle.

[SonofaBish]

hahahaha....

I had no idea that's what he was going for... i just figured a "recipie" was what he called his plans for what all he did to his car...

Sorry Punisher, you gotta admit, that's some funny shit

[PunisherStang]

wow i didnt even realize that i wrote that lol haha....i was reading it at 7am in class an didnt even cross my mind for a second that i was cookin lol....i meant recipts or how ever you spell it....i got a good recipe for grill chicken tho lol:goodidea:

A lot of the mod motors they dyno dont have all the accesories on them either...gota take that into account.

thats a very good point. didnt even pay attention to that
