Worth It?

Sherwin · Jul 7, 2012

I'm enjoying my first Mustang 100%, don't know why I waited this long to get it. Its a 1996 GT Convertible with 160k kms on it (about 100k miles). Manual trans. Has a nice sounding magnaflow exhaust with O/R "H" pipe, CAI, and SCT tuner to boot. The car has some rattles and collected "character", but isn't too bad for a 16 year old car I suppose.

I'm considering doing a few things that I've read are a good idea from this site. Subframe Connectors seem to be a must, I'd like to change the rear end to 3.73 or 4.10, and I'm tossing the idea of a Kenne Bell S/C. I'm hesitant with the KB because of the miles on the car. For a daily driver would it be fine or is it possible the motor is spent past safely running a blower?

Thanks in advance for your input...

Do a compression test. Should be fine with a safe tune.

If your dead set on a Twin Screw blower stay with 3.55's or 3.73's. 4.10's will be too much for stock 245 sized tires. If the car is properly maintained and tuned, you can supercharge or turbo anything. I put a Vortech on my car at 132k miles. I'm at 154k now..non intercooled and in FL. I run 3.73's with the Vortech too, plus it is my only vehicle. I've had my timing replaced, water pump and idler pulleys all fixed to make sure nothing bad happens. Just always run 93 octane and be sure to get a wideband just in case too.

Thanks for the replies. I wouldn't say I'm dead set on a Twin Screw type blower, but they have the most gains per $ spent from my research. I have a great deal on a full set of PI parts for the PI head swap as well.

What should PSI be on a car like this if I check the compression?

usaf_branham · Jul 8, 2012

if you dont plan on using it as a quarter mile car, 4.10's and a KB is fun as hell on the street. if you run the quarter, you will hit the rev limiter in 4th.

Sherwin · Jul 8, 2012

I don't get into the formal racing thing. Its more of a goof off car with my kids, cruise the local Broadway and to the lake sort of thing. Occasional highway run...leaning more towards 3.73 to keep revs down on the highway, but it would still be a huge improvement over the 2.73 in it now for fooling around...

if you cant do the gears and SFCs at the same time, id personally do the gears before the SFC's...gears have much more of a fun factor IMHO

Sherwin · Jul 8, 2012

I agree with the gears, and being as they're relatively cheap and "quick" to do, I'll be doing gears and the subframe connectors pretty quick. Does anyone have anything to say about the bolt on connectors vs the weld in style? I can easily install the bolt in ones myself, but they cost more. Weld ones are cheap but by the time I have a shop install them would be a wash likely...

Opinions? Educated thoughts?

If your going with subframes go with the weld in. It will be much more structurally sound...

I read somewhere that you should pull the floor carpet up to avoid burning it when welding. Is this BS, or a legitimate concern?

AZmustang98 · Jul 8, 2012

Does Kenne Bell even make the manifold for NPI heads anymore?

Sherwin · Jul 9, 2012

according to their website yes, a non-intercooled 6-14psi kit...

Thanks this is good to know! I was wanting to order some, and I saw his comment about the carpet and I was like but then you saved the day.

Definitely full length weld in SFCs, and upgrade your suspension & tires if you're planning to KB supercharge it. The KBs make a ton of torque, so you'll have a lot of fun tooling around town with it. I'm a ProCharger man myself, but my dad has a KB on one of his Mustangs and an Eaton on the other. They're both a lot of fun to powerslide around in.

Sherwin · Jul 11, 2012

Is there pro's/con's to either one? The pricing seems similar, yet the gains seem much more impressive with the twin screw style vs the centrifuge style...Ease of install on either? Has anyone worked wit both?

Right now the car sits on Sumitomo's, and I've recently put an Eibach Lowering spring kit in it...

N8Dogg98 · Jul 11, 2012

KB > centri IMO. I prefer the flat torque curve though.

Guy I know locally had a KB on his '04 GT and it put down around 430 RWHP (car has a forged MMR 4.6). He sold the KB last year and installed a on3 turbo kit. Car now makes 560+ RWHP.

It's funny, the KB felt faster because it slams you in the seat right off idle, but the turbo has this OMG rush of acceleration once it spools up (similar to the vortech just more aggressive).

You decide what you prefer. Flat torque that's available at any RPM (more fun on the street IMO), or a rush of top end power that pulls harder and harder all the way to redline.

The KB is a "twin screw" style of supercharger, also refered to as a "positive displacement supercharger... Centrifuge superchargers would be that of Vortech, Paxton, and others that resemble a turbo assembly but they're belt driven instead of spooled by exhaust pressure...

Uhhh, no kidding.....

We're not a bunch of car noobz (well most of us).

^ what these guys said, re positive displacement vs. centrifugal.

A lot of low end torque is fun screwing around in town, but when you shift at 6000 rpms and land at 4000 in the next gear, torque at 2500 rpms is not useful. I prefer high rpm power, but plenty of people see more fun burning the tires from stoplights than winding out a motor. I'd choose a turbo or centrifugal every time, but that's not the right choice for everyone.

You'd enjoy both, so I wouldn't make a decision based purely on cost.

Sharad · Jul 12, 2012

There's no right or wrong answer, but I choose ATI ProCharger.
