im looking at parts already to try and get a rough idea of how much it will cost next year to start builidng my mustang and im wondering a few trhings.

I was looking at the Whipple HO Kit http://www.modernspeedmachines.com/c...roducts_id/485 and was seeing how much power it puts out and im guessing this is prob the best or one of the best superchargers for the Mustang.

But i was wondering if there is a turbo kit out there that puts out just as much or more power....or like a twin turbo kit im sure puts out more. But which would be the better choice....a trubo...twin turbo....or supercharger. The car will be a daily driver but also a track car on the weekends.

Then secondly i was wondering......what am i looking at price wise and parts wise for a suspension to put this power to the ground.
ive been in the lifted suspension scene for the past 2 years so im way behind on my mustang perofrmance parts.

Thanks All
Patrick

turbo will almost always produce more power, and it is alot better on your engine.. only downside is it is so damn expensive

[patshea098]

But that whipple.....10 PSI on 91 Octane does 525 RWHP
and it goes to 12 PSI. i mean id prob never go to 12 PSI cause the stress on the engine, id probably keep it down at like 8 PSI for street driving and then 10 maybe 11 for the track.

What do you think about twin turbo??? is that TOO much for these engines??

The whipple HO kit is very hard to beat! It is the best of all the superchargers out there when you factor in what comes with the supercharger kit. An average whipple HO kit on a stock 05-07 GT will put out 460-475rwhp and you dont really want to go over that on a stock motor/drivetrain mustang...

I am having a Hellion turbo kit put in this week coming up because of the way my engine bay is set up with the shaker ram air kit I have on it.

My dyno shop here in town will Order, Install, and custom tune a whipple HO kit for $8,000 (this includes the taxes and handling as well)

My turbo kit will cost about the same even though the turbo is cheaper, it is harder to install... I'm looking at about a $8,500 price tag for my setup but that is also including some motion delete plates...

[patshea098]

motion delete paltes?? how much power is that Helion suppose to put out?

Well i dont remember what X-M-P was going to do to my engine on top of the pro charger they were going to put on my mustang 2 years back, but they were doing it so the engine could handle 10-12 PSI i remember which is just like what the Whipple does.

So what all do you think id need to do to my engine so i can use my 10-12 PSI???

The tranny i will have rebuilt from the auto, to do a auto clutch ratchet shifter. Kinda like having paddle shift on the steering wheel except it automatically downshifts, and you shift whenevr you want simply by tapping the shifter button.

[Regency 2007]

if you have an auto then I would def. steer away from turbo but you can make it work, it is just hard dealing with the transmission...

The whipple HO kit puts out 10PSI that is a high as you wanna go before you start risking your car...

if your car is still not fast enough for you then.... Just throw in a steeper rear end gear like a 4.10 and throw some sticky tires on

my hellion kit should add the same power as most of the supercharger kits that are out now, just at a lower boost level (8psi) and the delete plates I have been told will add around 8-10rwhp

[patshea098]

O im for sure going to throw in a higher gear ratio in the rear.
and im probably going to throw on some Nitto Drag Radials or something.

Just wondering, but this is one thing ive never heard of, why do you want to steer away from a Turbo when going with a Auto??

I really like that whipple kit...i think its a good price for its power and hwat it comes with compared to the other kits, let alone Whipple is also very reputable.

Do you think it would be dangerous to run the car at 10 PSI as a daily driver? and also would it be dangerous to run it at 11 or 12 PSI just when doing quarter miles at the track??

You are the Josiah of these mustang forums (Josiah is a guy on my F150online forums whose very smart about trucks and mods).

Now that i got a good idea of the direction ill be heading as far as supercharger vs turbo......what am i looking to spend on suspension to keep this power to the ground??

[Regency 2007]

I use to be on f150online I know who josiah is, my name was superfx4 but when they heard that I bought a nice mustang and was going to d some nice work on it they all got pissed/jelous and so I just left...

I am not really smart on turbos and automatics... There is something that has to do wit the torque coverter or something, for instance you will run into problems driveing down the rode and decide you wanna romp on it with and auto/turbo, someone else on here prob. knows better...

If you go supercharger, I would def. go whipple! This is my tuner in town and you can check out his website www.dynospeedracing.com you can call up there and ask for Joe, he will tell you everything you ever wanted to know! One man brought his wifes stock automatic GT i there and had a saleen supercharger kit put on and some slicks/gears, te car went low 11's in the quarter mile so that is knocking off 2.5-3 seconds of your quarter mile time!

12PSI at the track will be a little sketchy, I would not do that on my car, but if you got the money to upgade your internals and want to, then go right ahead...

[Regency 2007]

I dont know a whole lot on suspension... Joe at dyno speed recommended some control arms to me, but I am going to wait to see how it does after this week when I get the turbo on... my car has been lowered 2"s and is on some pretty wide/tall toyo tires... I am hopeing for low 11's my first time at the track!

[patshea098]

oh its you superfx4 .....well my name is the same on here as it is at f150online...

But yea i think ill go ahead with a Whipple when the time comes.
I mean i still have another year haha....maybe some other car will come along....though i like to stick with Ford and have some kick asss plans for my mustang.

My plan so far is:
Whipple HO Kit
3.73 or 4.10 gears
20" rims of some sort.....but probably just 18;s cause there isnt a drag radial in 20's
Custom Auto Clutch Ratchet Tranny.
California Dream front bumper, side skirts and fender flares
3d Carbon Rear Bumper
Replace all interior seats to color match.


thats what i know for sure so far.

But everything i do will take a good 2-3 years.

[Regency 2007]

my vote goes for the 4.10 rear over 3.73, I have 4.10's now and am kinda second guessing as to if I should have got 4.30's but now since I am going from 290rwhp to 480rwhp I think the 4.10's will be perfect, I have 20's on my car and it really makes the car stand out and improve the stance really good!!! I cant tell you how many hundreds of people have commented on my car! If I really get into the drag racing I will just buy some chepo wheels and some M/T' to go on them

[patshea098]

yea i was thinking the same. my truck had 3.73's stock and now i have 4.56's for my big meaty tires......4.10's sounds good for all that power.

My 06 GT was hit while parked infront of my house, New headers and exaust where only 20 days old. I just got a 07 w a few addons. Had to make it new and improved. Got the 3:55 gears. Basicaly its a non registerd Stage 2 Roush +. All the stuff a stage 2 has just assembled for less. The plus is a roush intake, short throw shifter, eddelbrock headers ford racing handeling and lowering kits, and 20in Shelby rims. How hard is it to use a preditor and is it worth it? I had a 98 GT w a Vortec S trim. Was fast and fun, untill it started making a god awfull noise. I sold it got the 06 it was hit and now I'm building my dream. Turbo? Who? How much? I was told I can hit 550HP. Hope to get some good input. I want a 11 sec car one day. One that will eat up all the little euro/ rice-tunes. Damn things sound like lawnmowers.

[patshea098]

your stang now should hand it to those immport guys asses.

and a 11 sec car deff will...unless its a older RX-7 or supra or somehting...than look out.
there some really fast 350Z's and infinitit g35's out there so watch out.

but other than that your good and with all that pwoer youll hand there asses to them.

One is not better than the other. They are just different, and each has their own advantage. Turbos & centrifugal superchargers make better mid to high rpm power, while twin screws (read: Whipple) & roots type blower make better bottom end power. It also depends greatly on picking the proper size unit for your car and needs.

Learn about Twin Screw: Twin Screw

Learn about Roots types: Roots Type

Learn about Centrifugals: Centri S/C's

Learn about Intercoolers: Intercoolers

Learn about Turbos: Turbos

So the bottom line is:

A. Decide what you want to do with your car. 1/4 mile warrior? Stoplight demon? Or highway beast.

B. Decide how your car will be built. Going to strengthen the bottom end? What compression ration will you be running? What cams will it have? Going stick or auto? If auto, what stall converter? Full manual valve body? What gear ratio out back?

C. Decide what fits your car the best. Have a stock engine, and will be doing lots of highway driving? (that's me lol)A single small turbo set at a moderate psi will fit the bill. Going to replace the bottom end with real parts, & assault the 1/4 mile? I'd go with a large displacement Kenne Bell twin screw, intercooled unit.

[patshea098]

well i want to run some good times at the quarter.

but for the most part ill be a stoplight demon.
and it will be auto with 3.73 or 4.10 gears.

[Regency 2007]

I would go 4.10's I almost wish I had gone 4.30's with my taller tires I have on but the turbo kit will fix that!

[patshea098]

almost seems that 4.10;s will break my tires free to easily and for too long.

i dont know about gearing in cars....i mean i have 4.56 gears in my truck but then again i have 38" tires with 18X10 chrome wheels on.
plus its a 6000 pound truck

That's what all your suspension work & a sticky drag tire is for, to make the car hook.

[patshea098]

yea so with the suspension and drag tire...4.10's is low of a gearing, and 3.73 is fine.
