3.2 performance upgrades

[yama1]

What simple performance options are available for the 3.2.

Increase in HP, but at this time cannot incur too much cost

Air filter, exhaust, manifold mods. Don't want to pull engine now, I'll save that for the rebuild.

thanks for the info

premuffler / muffler - Steve W chip

What gains do you get with the dansk pre-muffler and 2 out

How good is the steve chip on the us model - I read another forum going round and round about the dyno

thanks,

Any Motronic Experts out there?

On my car the difference was nothing short of amazing. To think that people are charging 100 bucks for cone filters and fancy air filters that make alot more noise than hp, Steve's chip is a bargin.

IMHO

SteveW chip all the way. That's currently the only upgrade I have and it was well worth the money. Made the car much more fun to drive, and generally more drivable around town.

Exhaust = good. Chip = good. Air filter = almost useless.

at last dyno figures for 1986 3.2 with dansk premuffler/sport 2 out muffler

Chip?
Read the FAQ page Question 2 on the Andial web site (www.andial.com).

Don't get sucked into buying junk chips which do little to nothing!

Good Luck

Andial is saying exactly what everyone with sanity has been saying here for a long while-exhaust mods + an appropriate, conservative chip will give you a minor hp increase, and maybe some subtle drivablility increase as well.

[RickM]

Adding an additional exhaust tip to my stock muff was the best bang for the buck. Not huge but worth it.

A search will yield plenty of direction.

From the Andial web site:

"If you do nothing else to the engine but install a chip from a reputable
company, you can expect, on average an approximate 5 % horsepower
increase. "

They say REPUTABLE!

Also, remember: HP = Torque X RPMs

Assuming a fairly flat torque curve, then

At 6000 RPMs, HP for 3.2 is about 210 @ 5% that's about 10 hp increase
At 3000 RPMs, Hp for 3.2 is about 105 @ 5% that's about 5 hp increase

Not much to write home about, since most driving occurs at <<6000RPMs.
Plus, the problems with potential pinging, idling, & driveability.

Have Fun

'88 3.2, no chip

[RickM]

Don't you have to deduct 15% for drive train loss?

[Lorenfb]

The numbers make the point. Using RWHP the gain is even less!

OK so let's assume 10 hp on the 3.2 - Steve charges what? $280? - $28 per HP has to be some of the cheapest PORSCHE hp ever!

[RSupdate]

Depending on the smog regs in your state you can be limited to just a chip or various stages of intake & exhaust improvements.

In order to improve the engines ability to function as an air pump, which is all internal combution engines are, really, you can use the going hot chip, int his case Steve Wong's, to improve the fuel mapping.

Next you want to open up the intake side with a cone style K&N airfilter(not a H.P. inducing addition in itself) then a set of SSI's and then a dual out sport muffler.

If you have smog law considerstions and or a slimmer budget, you'll have to go the pre-muff/bypass route, which is almost as good as the SSI's, but still a compromise.

Everything above, together working as a "system" will give you a good amount of add'l punch when you put your foot into it.

Just my.02 ...good luck!!!

So who, in your mind, is reputable?

I've got a SteveW chip and cat bypass. I think it's totally worth the money. There are just not a lot of cheap upgrades for these cars, but this is one of them. Don't expect miracles, but there is a difference.

I don't think the power is up so much as the responsiveness and torque are better, especially in the low rev range. I find myself cruising around at lower RPMs. I did have the bypass pipe on without the chip for several months, and it is the chip making the difference. I did have the "more aggressive" of the two factory chips that Porsche put in the '88 cars to start with, so I'm probably seeing the least dramatic increase of anyone. But it was still worth it.

I agree with Wayne, Chip + exhaust (pre-muffler & Sport Muffler) make the car a pleasure and more sporting to drive. Made a nice difference in my 87, engine pulls much stronger above 1500 rpm. Put chip in first - that made a nice improvement. Once the pre-muffler and sport muffler went on, the improvement was very noticeable, nice sound to boot. I went with the Steve Wong chip, great people to deal with and will answer any questions you have.

[jakermc]

5% isn't significant? What car manufacturer consistently produces better results than 5% annual improvements? In 1987 the 911 had 217hp. In 1997 is had 285hp. Thats a 31% improvement that took 10 years to achieve. Pick other years and models and you'll see similar numbers. Now factor in weight. The 993 is a lot heavier than a 911 Carrera. The improvment in hp/lb ratio isn't nearly as good as just hp.

So you are telling me I can gain 5% hp without any weight gain for $280 and 30 minutes of my time? Sign me up!
