The listed q-mile time for the 89 TTA is the same as for the GNX (of which no more than 499 are in existance), but i'll take your word for it if you owned one.

The reason the TA handles better is because it's got a lower CG, and it's a bit lighter. The 89 TTA's also had 4 wheel discs didn't they?

TTAs were WS6 so they were 4 wheel discs, 16x8 with 245 Gatorbacks, big swaybars, etc. But the GNX did too.

You can buy a well-used TTA for under $10K, where a real GNX is double to quadruple that. Heck, even T-types are getting expensive. The Turbo TA is a bargain really.

The one thing I didn't like about the car was the stock torque converter. It was very loose and a pain in stop and go. And the TC was loud - whirring sound.

Not true.

Shocks, springs, swaybars, exhaust- all different.

I think you're probably off on the retail price of an 89 TTA. I saw one about 5 ago years for close to $20k with high miles...these cars are even more rare now. I can't imagine the price going anywhere but up on them. Though with today's economy, who knows.

GNX's were probably in $50k territory when the economy crashed, they may be much cheaper now too.

SLP only replaced the hood (and air box) for Ram Air, the rear spoiler, and their 17" alloys (chrome optional). They OFFERED a complete suspension package as a Firehawk option and they offered a couple different exhaust options over the years, but a base Firehawk wore standard T/A suspension and exhaust.

I know Ed and Dave Hamburger of SLP personally and have owned many of their cars.

It may be true that MOST Firehawks were opted with those items. Just like the Camaro SS (also by SLP). I owned one that was base, and one that had every SLP option including dual/dual stainless exhaust, Auburn limited slip, chrome ZR1 wheels, KONI Stg II suspension, logo floormats, logo trunkmat, car cover, and plaque. $8000+ in SLP options above the base SS package.

But the 930 was available in the US in the 1986 MY, and Car and Driver tested the detuned US version at 0-60 in 4.6 seconds and 13.1 for the 1/4 mile, according to the Porsche "Rocket Scientist" ad.

I don't think the 930 qualified as a "production car."

It was also probably about 4 times the price...

A GNX was about $26,000 sticker new.

For $1000.00 it can have 400plus horsepower, literally. And run mid-12s.

But whatever, to each their own. And i don't see how the 930 could be considered production given that it's not listed in any of these other 'fastest car' articles that were pasted into this thread.

For many of these same years Porsche was claiming the 928 as the fastest production car sold in America, but based on top end.

So what? The original article quote didn't cite the figures for the Countach because they weren't being delivered, not because they weren't a cheap car.

I forget sticker on the Countach, but when I read a review of it back in the day, you could buy about 16 perfectly good used drivers for the price of the optional rear wing...

Err, so what? For some sum of money (purely nominal, I'm sure), you could have a 962 or 935 transplanted into a standard car shell. Jerry Woods, Protomotive and Cabas (sp?) all did it back in the day. And Bello was running 9.17 at 161mph in his TT six years ago.

All totally irrelevant to a discussion of 1986 MY Production Cars.

As is Ray Williams' NZ two-way averaged NZ Land Speed record of 196.72 MPH in a road-registered (and street-driven daily transport with leather seats, carpet, alarm, electric windows, heater, sunroof and a stereo), modified 1983 930 http://www.williams.co.nz/index.mv?page=landspeed that he's won 116 races, 3 championships and set 8 land speed records in.

(Which also makes 0-60 in 3.8 and a standing kilometer in 20.69 seconds - as compared to a Ferrari F40/F50 = 20.9 seconds. That's roughly a 10.8 1/4 mile.)

If you could buy it off the showroom floor, I don't see how it could not be?

So "fastest" is 0-60, 1/4 mile or top speed now, I'm losing track?

Porsche's advertising for the 928 was true for the US market, until they re-introduced the 930 in 1986:
