Please help!the best Bolt on Hp for 3.2

[YermanCars]

I Need HP for my 84 3.2 without taking out the motor. Ive read many post and I just dont know what to do. the only thing I have is a b&B cat back system. I bought a weltmeister chip, returned it because of autothority chip. Almost bought it ,but wanted the Autothority Maf, Ive read post on the MAf, some say not worth the $$$. How about a custom chip is it hard to do. Im lost please help.

[juan ruiz]

It really depends how much HP you wish to have,you could
BOLT ON a Turbocharge !

[Kemo]

You could always unbolt some things and save some weight (ala KurtB).

[ChrisBennet]

You would have more smiles per dollar if you spent the same money on Drive Ed events IMO. Try one before you start hanging parts on you car.

All very good suggestions, but the fact of the matter is, it comes down to what your budget is and what sort of HP you are looking for.

HP costs money and is directly proportional to how deep your pockets go

The easiest & cheapest would be weight savings and a Driver Ed session/events.

Once you do that, you can then start doing performance upgrades. Best BANG for your buck is forced induction, whether it be supercharge or turbocharge.

Good luck...

Don't you mean most buck for the bang

[Bigbartguy]

email Steve W if youre looking for custom chip at a reasonable price.....very similar to the 'A' chip you mentioned. He'll tailor it for your exhaust setup. Chips arent going to turbocharge your car though.

Get a Euro pre-muffler from Fabspeed also. These 2 along with a free-flow muffler will probably get you your best bang for your dollar, w/o breaking the bank.

MAF is not worth the $$$ from what I've heard....but no personal experience.

[RSupdate]

Do you have to smog your '84? I don't know what that requires in yr state, but if you can, try a pair of SSI's. Check out my sig below, other than that it's stock internally. I also had a custom chip mapped out by Autothority after telling them about my car and and engine combo.
As an added bonus after I installed the new all stainless exhaust system, I immediately noticed the rear end rose up a good inch at least, due to the removal of the excess weight from the stock exhaust /cat etc.

I have no complaints about the performance of my 3.2, and still have the stock reliability.

Just my .02

If you've decided your car is not fast enough, you first may want to start looking for a car with more HP, perhaps a turbo. Bolt ons will ad some small amounts of hp here and there, but not enought to change your opinion from what it is originally. Just enough to make you dissapointed. I actually enjoyed the gradual addition of parts and changed to my car and have always thought of the power as being adequate. The changes I have made are: SSI's, Sportmuffler, Huntley Racing programable MAF, bored throttle body, adjustable fuel pressure regulator, Authority chip. How much did this cost? I figure about $3300 without labor . How much did I gain? I figure maybe 20-30hp tops. One way I can estimate the gain is that my car pull evenly with C2's on straights at the track. My car has 60K and alas, the dreaded valve guides are appearing to become and issue. While getting them done, I am contemplating a different crank, larger pistons and possible a different induction system. Fortunately, I can use most of the previously mentioned items. Ramblings aside, bolts ons are not going to transform your engine into a beast.

[juan ruiz]

Well we must go back to the original question how much $ you want to spend and how much hp, thats the only way to really make a good combination .Let us know so we can help!

Early style exhaust and maf kit.

[dickster]

imho and from what i've read - early style exch aren't worth the money on the 3.2. but if anyone wants to provide dyno figures i'd be interested..........

euro premuff/sport muffler first. for about 12hp, thats what i've done and dynoed (see thread).

beyond that, i hope to do the maf thing next (early next year) in combo with chip. i'm hoping for at least 10hp, so i'll have around 242+hp. i'll again get it dynoed. i'm not into the "seat of pants" dynos!

b anderson rates the maf, and he seems to know a thing or two!

i think the main issues are driveability with the maf. i am going to use amd (see website) in the uk. i hope to do the stage 1 promotive turbo one of these days and hope that the maf will compliment it.

beyond that, the skys the limit - but i hope to be happy with that.

again it all comes down to the dosh

Read Bruce Andersons Porsche performance handbook.

In it he states that the unequal lengths of the stock exhaust on the 3.2 is one of the biggest inhibitors of getting the most out of this engine. He also states that the best "chip" for a 3.2 is an exhaust change, and he specifically suggests to use the SSI heat exchangers and a dual outlet sport muffler. There are dyno figures in there as well that that illustrate his findings. The best increase's were found using a 3.0 ltr SC motor where they got something like 20hp more.

H'ver he also goes on to state that the 3.2 is about at the top end of the SSI's ability to expel all the exhaust gases due to the larger dispalcement and any larger disp. would require a bigger diameter of tubing. Thus the gains achieved from SSI's on a 3.2 were a bit less at around 12-13 hp if I remember correctly. I'm typing this at work so I'm going off memory, If I were at home I'd quote directly from the book but I studied this info extensively prior to doing what Bruce suggested to my own 911.

Again, read Bruce's Performance handbook, it's all in there.

[juan ruiz]

What ever you do DO NOT really on figures from ANYONE!
the DYNO is the JUDGE! you be surprise how misleading must of this HP claims really are.

[Milu]

As already posted it depends on what you want to achieve and how much you are prepared to spend. And also what compromises you are prepared to put up with.

However, here's a little food for thought:

Why? If your car is not fast enough, are you sure it's performing as it should? Are you sure you're using it to best effect? A good standard 3.2 is already very fast.

How are you going to be using the car, is it a daily driver or a weekend toy. Lightening the car is cheap and effective but can you live without ac, radio, heater, comfy seats, soundproofing etc? Can you live with whippy fibreglass doors, acryllic side glass that scratches and a fragile fibreglass front that might not offer crash protection on a car you use every day? Similarly a sports exhaust can become boring very quickly when you have to put up with the noise and resonance in stop start traffic as well as a *****ing nagging distaff. A wild camshaft can also lose it's attraction on the daily stop start commute. A car is made up of compromises, before you start adjusting the ones made by the factory understand why they imposed them and the costs of changing them. Some modified cars can be horrible beyond belief to use outside a specific application.

If you want to hit big hp numbers forced induction is the best route. But is reliability and longevity an issue? It might be easier to just get a 930 or transplant a 3.6.

If you're just looking for a little more power and want to keep the car friendly and usable I would suggest MAF, bored throttle body and a custom chip.

[WydRyd]

If you wanna retain the drivability/response of natural aspiration with BIG HP numbers, I can only suggest one solution, which is cost effective compared to any other (engine transplants etc etc).

For $8k, get a Protomotive Stage 1 kit and you'll see north of 275HP AT THE WHEELS, or 320 engine HP. Low boost (7psi) + stock compression + reliability of Protomotive's years of R&D = BAGS OF FUN!!!

If reliability concerns you, Mike, Juan and I can put your mind at rest. If you're still not convinced, have a chat to Todd Knighton (knighton@netquest.net) and he'll address all your concerns.

Talk to someone who REALLY knows turbocharging! Todd is da'man!

Come join the dark side young SkyWalker...

[juan ruiz]

Merv You are killing me! the DARK SIDE LOL
See we see things diferent and we are willing to take chances so I give you a example you go and spend $2,000 in this SO CALL MAF KIT (you can try the one from Authority with the FORD parts on it)which is not what everyone dreams off !you install a Wonder Chip $ , Some brand name exhaust (which 98% of them are junk) $ and what do you really have ? Not much I can assure you this,If you want to install a chip,exhaust and a few things and leave it alone then you be FINE, other wise all that $$ that you invest will be GARBAGE in the next step,
Now for $6,000 or so, you can have a turbo and as Merv point out 320/276rwhp if I did't blow my up mine NO ONE WILL!

But of course it depends on opinions! must people tell you what they read or hear but how many have EXPERIMENT with this set ups?

Again thats the point of view from the DARK SIDE

Hmmmm, the FORCE is strong with this one Juan

Couldn't agree more! If we (Juan, Mike and I) haven't grenaded our engines yet, then no-one will. I've thrashed the living Ewoks out of my car and it hasn't skipped a beat yet.

The main thing is to ensure you service your car at regular intervals and refresh the oil just like any 930 turbo. You have to remember, the 3.2 Carrera has the same internals as the 930 anyway, so strength isn't an issue, AND as long as you don't go over the top with your boost levels, reliability won't be an issue

In the end, it's your money and your decision.

As Morpheus (The Matrix) would say:-

Unfortunately, no-one can tell you what the "Dark-Side" is, you have to see it for yourself.

You take the blue pill and the story ends. You wake in your bed and you believe whatever you want to believe.

You take the RED pill and you stay in Wonderland and I show you how deep the rabbit-hole goes and how much HP you can make

Remember that all we are offering is the truth. Nothing more.

He also states that the best "chip" for a 3.2 is an exhaust change, and he specifically suggests to use the SSI heat exchangers and a dual outlet sport muffler.

like you said the gains are around 12hp - which i got with euro premuff/dual muff. theres a thread around somewhere with a quote from bruce (don't think its in the book, maybe "excellence") saying to use the combo that i have, because the ssi's wouldn't gain much more.

[jyl]

WydRyd & Juan, how would you compare the Protomotive (sp?) Stage 1 turbo kit with a supercharger kit such as the Superchargers of Knoxville Whipple-based system?
