how can I make an 86 faster?

[mm86911]

Assuming you're keeping the 3.2 then think seriously about changing the ring / pinion to 7.31 ratio - instant acceleration improvement for street, track and autox.

Jeff:

I have an 87 Carrera. All it took was a handfull of laps around a road course circuit to conclude:

(1) My car has more than enough acceleration, (2) My brakes are great, (3) Every $ I spend on performance will go into suspension, seat time, and adding less weight. I do not want a dedicated track car, so a roll cage, harness, and race buckets are a no no for me.

If you want a crisper throttle response, a Steve W chip may be worthwhile for you too. I have had one for a year and it is great.


Finally, I just got back from a 700 mile trip up Hwy 1 in California. It is a lot of high speed mixed with a gaggle of tight twisties. I was NEVER wanting for more hp. A more balanced and grippy chasis would have been nice though.

Good luck.

Concur with the guys on getting DE time. I've done it in my Carrera and in my 993 and have had my a$s handed to me by older, slower cars with great suspension and more experienced drivers. After my first DE in the 993 I swore I wouldn't spend another dime on HP until I had upgraded suspension and done a few more DE's.

Well, now I'm there. My Bilstein HD's and H&R springs are about as good as it gets, so I'm spending money on another DE and will start planning an engine drop for light-weight flyhweel and RS clutch kit, maybe even a Euro G50/21 gearbox. But this is gratuitous stuff mainly for street driving. A stock Carrera does just fine on the track and you'd be amazed how much you can get out of the car with just more seat time.

To really make it go faster, toss it out of an airplane at about 30,000 feet!

The usual way is

• cams
• compression
• displacement
• gearing

[jeff1hughes]

OK, I'll do some DEs, get the chip, then work over the suspension. Once all that's done I'll drop it out of an airplane at 30,000 feet. Anyone have access to a C-30 that I can borrow?

What can be done for cams on the Carreras? I haven't heard too much about a better profile on the 3.2s. But, that is why I posted the question!

First and number 1 upgrade is the nut behind the wheel (you). Do at least one DE - I found I had plenty of power.

from there - Steve Wong chip, Dansk premuffler, Sport muffler. - you won't gain much for the $$ from SSI's.

From there do a search on Stage II Turbo from Promotive.

[Bill Verburg]

I suggest that a search is in order. There are a whole bunch of guys that have used different cams w/ good results. The main caveat is that the Motronic metering system limits the lumpiness that can be used.

[Randy Webb]

"lumpiness'

- a good term -- not just for cams but for many of the answers posted on this and other BBS's

BTW, you need to think about what is legal, and what is affordable. It is a lot cheaper to do thought experiments than to rush in with a wallet and a wrench. good luck.

[Shaun @ Tru6]

I second everyone who said spend some time on DE.

My 84 is plenty fast with just a weight reduction plan and a SteveW chip, but what made it a great car to drive fast was a complete suspension R&R wtih bigger T bars, Elephant Racing bushings, Bilstein Sports, turbo tierods, lowered and corner balanced.

For weight reduction, I
pulled entire AC
Momo Corse's for driver and passenger
Minimal interior... no back seats, no carpet, console
No spare tire, but a can of fix-a-flat and tire repair kit

[Randy Webb]

SUre a DE helps you drive faster on the track. But reread his comments - he is looking for certain things -- and they aren't particularly well correlated with DE experience.

[jeff1hughes]

Thanks for understanding Randy. But I did get plenty of help from everyone, and I do understand the importance of DE events.

[WydRyd]

Do a search for "Juan Ruiz" on this Forum and you'll see how to make a 3.2 FAAAASSSSSSSSSTTTTTTTTTT!!!!

Red: stock chip
Blue: performance chip (that you can purchase everyday at Pelican)



From Tomturtle's '88 Clubsport.

When I first got my SC it had ok power. But I am a turbo guy so I put a 930 motor in my car. That was the single best thing that I did to my car. It made my Porsche go like it should.

Dean, lets keep it real. I would not put a engine transplant in the same catagory as a chip and exhaust modifications. I would hope your car is faster. Not everyone wants to dump the engine they just got with their car and then spend another $10,000 for engine work. I think they would of just bought a turbo instead.

[dean]

Jeeze I was just telling the original poster what I did to my car to make it faster. I don't think I implied that a turbo is in the same catagory as a chip and exhaust.

Any particular reason the dyno graph is scored at a 6200rpm instead of a more realistic chip comparison at 6K?

[Steve W]

Basically with the stock chip, peak hp is attained at 5900 rpm, as shown the owner's manual and multiple dyno charts, as can be seen here:

http://www.911chips.com/dyno.html

With the performance chip, the hp contines to rise past 5900 and a new peak is reached at around 6200 rpm. As you can see, at 6200 rpm, the engine has gained 22 rear wheel hp, an equivalent of 26 crank hp. That is a 12% gain in power. Past 6000 rpm, the engine power seemingly continues to rise and pull until the rev limiter hits, whereas with the stock chip, the engine seems like it hits a wall after 6200.
