Horsepower guesstimate

[04-SVT]

Hey guys. I need some input on some guesstimates..
Im thinking of De-tuning my car abit.. Making it more street, driver friendly
My car is to powerful for everyday driving and no Im not bragging,.. It just has to much torque I think. But I was thinking of removing the turbo kit and keeping it N/A
Here is what I would have without the turbo kit:

AFR Heads 185's, 68cc chamber if I remember correctly
331 cubic inches.
SRP dished pistons
8.8 compression ratio
Crane 2031 cam (im pretty sure that was the number)
Holley systemax intake
Lightning 90mm air meter, 42# injectors

Ok, so here is the deal.. I would keep most mods, except remove the turbo and get a slightly more agressive cam, but I would be putting in flat top pistons that will increase my compression ratio to 9.7...
So with that in mind, I will have these mods:

heads as listed above
still 331 cubic inches
SRP flat top pistons
9.7 compression ratio
"stage 2"? cam.. more agressive then what I have but not outragous
same intake and lightning meter and injectors, headers, xpipe, exhaust obviously

So my question is.. With it normally aspirated, what kind of power would I be making? estimates.. How much of a jump is from N/A 8.8 to 9.7 compression ratio?
Im thinking very seriously of tearing the car down again and starting from scratch. Mostly because Im not driving it much anymore and my girl is scared of driving it cause its to fast... And I think if I de-tune it, I would drive it more frequently too.. kinda be able to "cruise" it more
Also I should mention I was thinking of cutting the heads to increase compression too, but first wanted to see whereabouts I would be by pretty much just swapping the dished to flat top pistons and a different cam.. so yeah

just get a smaller turbo or turn down the boost, that's easy and cheap

this could be the dumbest thing I have ever heard.

My car made 700 something to the wheels, 1 month ago I went and had it tuned to make around 550hp, and i am very happy with the way it is now. You have a turbo turning down the boost is as simple as adjusting the BOV.

you will regret taking everything off, now if nothing is working right, and after 20 min of driving your whold car is heat soaked from turbo then I could understand this.

What kind of numbers were you making with the turbo?
I think Mid 500 hp is very streetable

 

[SMOKEDYA]

I'm thinking you will love the driveability you get from removing the turbo kit! And i also feel that you need to sell me that turbo kit for my 351! peace

lol, just worry about getting the 351 tuned and running good first john

this thread reminds me of a quote from super bad... "a breast reduction is like slapping God across the face for giving you a beautiful gift"

tearing down a turbo 331 because your girlfriend can't handle it is pretty much the same thing... don't you have a boost controller?? it's easy and cheap enough to just turn down the wick on the boost numbers withou spending a huge amount of time and cash on a teardown you WILL regret eventually

PS- what was your logic in picking up a 331 turbo fox for a daily driver anyhow? how about a $500 4-banger honda POS?

i say ditch the girfriend and keep the turbo.

i say ditch the girfriend and keep the turbo.

HA HA HA!!! +1 no im wit S&B detune a little boost dont declaw dat beast

 

[bentley429]

Buy a pinto, clearly thats what you should be driving.

So much for some civilized answers,, lol but whatever.. You have your opinions..
The car puts down 550hp and 680tq to the tires on a dynojet on a 90 degree day
I guess I should of also put down that the car overheats.. I live in Vegas and 110 plus degree weather is an everyday thing here in the summer time and quiet frankly, Im tired of driving around cause if I turn the A/C on it over heats and without the A/C its always around 230 degrees..
And before anyone says anything, the radiator is the biggest I can get to fit, 2 row aluminun, the fan is the biggest I could get and its controlled by the DCC controler. I even added an engine oil cooler with an electric fan.. Still gets hot. the whole A/C system has been looked over and everything is fine. I tried spacing the radiator and the condenser away so there is spcae, but nothing seems to cool this beast down in the summer time. So, yeah, Im pretty much tired of overheating.. And the lowest I can turn the turbo down is to 9 psi and yeah it still over heats..
So I figured if I "de-tuned" it abit and make it N/A and just pack a mild punch, it would help...

 

[S&B]

now dont jump on me, opinions are like a holes and there is a ton of them on here and Im one of them.

But I was having an overheating problem for a year, and It ended up to be the DCC controler (IM NOT SAYING THEY ARE BAD THEY ARE GREAT DONT FLAME ME) So i ditched it and went with a simple switch and now I cool fine. For some reason the DCC controller was not sending enough power to the fan and i even ordered the 60 amp one. Just ry hooking it up with a switch to see if that help you. I didnt drive my car for a whole year battling that problem.

#2 It looks like you dont have any special block, looking at your specs. I split my stock 331 block in half at 20 more hp than your at right now, and less tourque, the block was fully girdled and personally blessed by the pope level 37. Your are dancing with the devil where your at. I would have the car retuned a bit lower. I dont see what style of engine mang. you are using. FOr a boosted car to run at the right temp its very imp that your not pig rich all the time. some tuners who are unsure when tuning want to give you a rich setup so you dont lean out and blame a blow up on them.

I know exactly where your at ive been there many times pissed off that you have the right setup but nothing seems to work ever. if you woman is like mine she teases you about your car never running right and that gets you going even more.

If I were you (and Im not because im way sechsier) and I just can get this heat thing figured out I would first pull the turbo and run N/a with what you got right now and see if the heating situation is really from the turbos or if its from something else. If you could post some pix of your setup under the hood we might be able to see some of your issues that your addressing.

good luck buddy and stick with someday it will all be figured out, a hoped up 5.0 is like Hooker you have to dump a bunch of money into it and at the end of the day you get about 5 min of enjoyment.

Ohh btw what fan are you running?

 

[bentley429]

Just buy a daily driver and leave the fox alone, case closed.

 

[white 89 GT]

I would sell it to one of those turbo lovers and let them deal with all the problems and take the bucks and get something n/a and pleasurable to drive.

 

[90lxcoupe]

theres always bugs to work out with any car thats making alot of power, if you cant handle wrenching on the car and having problems than maybe you should just detune it. Dosent sound like a fast car is what you want. If it were me i'd get the car running right, once you have the power, you wont want to lose it.

Just a heads up, there was no tone in this post, im not trying to be a dick, just stating the facts

 

[04-SVT]

See thats the thing.. I know I will miss the power, but I guess Im starting to feel "responsible" and been slowing down abit and having this overheating issue for so long really makes me think things over..
I also have 2 other "daily drivers" an 05 F150 and a 08 Honda CBR600RR, and in neither does my family ride in cause we dont fit.. So the mustang is my "family" car.. So buying another driver is out of the question. Besides, a car that looks this clean, I would want to drive more often, not park it and drive around once a week.
I have been working for Ford service department for over 10 years, so its not like I dont know what Im doing. I built that drivetrain from bare block to what it is now.. And I dont mind wrenching on it one bit, but it only gets you so far cause I have had this problem for about 5 years and everytime I upgrade something in the cooling system to findout in the summer that it still overheats, really gets to me, cause I have dumped tons of money on this car.
I had a supercharger on it before and it overheated, went turbo and overheated, so I have never driven this car without a power adder to find out if it overheats or not.

And regarding the controller, I have tried installing a relay so I had a switch feed it full power, but it didnt help either. I have tried higher flowing water pumps and different t-stats with different temps aswell.

 

[04-SVT]

oh and to answer the which fan am I running..
I bought the 18" fan (i think it was 18") from the same DCC control website.. It was cut to be abit slimmer so it would fit on my car.. but its not the Mark VIII fan.. but the fan is huge and pulls tons of CFM..

 

[mob]

I agree with buying a daily driver. Instead of spending thousands tearing the motor apart and rebuilding it, just buy a new car, and then spend money to make it faster instead of slower

 

[S&B]

IMO w/ what your telling me, I would sell your setup on ebay, in 1 week you'll have your cash, hell PM me what you have and some pix, and if I can keep my stock K member and I might buy your turbo setup.

You obviously know the right people b/c of were you work so maybe you can do a 408 buildup N/A thats what IM doing for my T top coupe, then you'll be able to run 500 NA hp and have a real streetable hp car. No matter what before you even think about doing anything I would just take the turbo's off and see if you still overheat, that will tell you alot.

good luck buddy i know how it is to be frustrated with the fing car

Tell me about it, it just got to the point where Im like F this! Im going to "start" over.. So thats where I am at.
Regarding the turbo set up, its the Hellion 62mm kit. I have the upgraded ceramic ball bearing turbo head and I didnt have to modify the K member at all.

 

[KamiKaziDK]

what radiator do you have in it?
