Nature of the beast??

WS6

Stay thirsty my friends
Being my first turbo car, I've noticed something different about my TTA that isn't the same as other 3rd gen cars I've owned or ridden in. It seems extra harsh out on the road and even idling. I mean you can really feel and hear the engine running in the interior. A couple of those articles posted here make veiled references to the "burbling" engine noise and crudness of the drivetrain feel and I was wondering is this the same for all you guys? Is it just the firing order and maybe engine mounts that transmit the noise and rumble throughout the car?

I know they have the WS6 package, but so does my '92 TPI car and it's much more mild mannered on the road. I mean they are both stiff cars but the TTA seems much more beastly in all aspects.

Are GN's this way??

You are correct. The TTA is different. That is what I like about it. The suspension is stiffer, I beleive it has to do with 1LE options or something.

The GN's ride very nice but the engines do idle rough. That is with the stock chip anyways. I still can't beleive how each car will smooth out with a different chip. My rough idle turned much smoother with a chip I got from precision turbo and got even smoother yet with my turbo tweak chip. Sometimes programming can make a huge difference with computer cars.

Enjoy your harsh ride and rough idle! It makes our cars unique. :-)
 
Thanks, that's reassuring to read. But do you hear more engine noise inside the cabin than other 3rd gen F-bodies?

Completely normal as 1 quik6 said. It is weird driving the GN because it is so quiet and soft. The tta rides like a damn tractor. I like it though.
 
Try and compare another 80's third gen. The '91-92 were constructed differently. they were a test bead for the 4th gen cars and used different sound deadening materials, better body joints and 130 some odd less separate interior components. I had an '83 Daytona T/A, and my parents had '85-86 tpi T/A's and they were similar in ride Quality, lots of squeaks and rattles:)
 
I had my buddy's '89 IROC for a couple days last summer,with similiar mileage as mine and it's a T-top. It was much quieter than either the TTA or my '92,but it's convertible so they are noisy by design.

It's not really squeaky or rattling I hear, but rather this sense that the engine is really a jet engine with solid mounts. Maybe you're right about sound deadening material and that the IROC having a V8 is just a smoother running engine than the LC2.

I can tell you that the TTA will out handle either one of the other 3rd gens I've driven. It's "right there" and has much better brakes than the others too.

The turbotweak chip made a big difference with mine as far as feeling the engine inside the car. It smoothed it out big time by just putting one of his chips in a stock car. My struts and shocks are still original and they have become slightly soft as they are coming up on 20 years old and I think that helps. I was going to replace them but I've bought several IROC's new back in the late 80's and my back still hurts from that ride. I also don't have one squeak or rattle inside my car. I find that strange. I remember coming home from the dealer in my 89 IROC thinking man this thing rides like crap. That car squeaked and rattled as soon as it hit about 10K. I still think the TTA was the best design ever. It was the best platform for that engine by far. Those IROC's I had were pigs! At least when you push down on the pedal in a TTA all that harshness goes away and turns into a smile :)
 
I am going to have to agree with the TTA's being a much stiffer ride than say my 87 GTA. But i happen to love the ride... Course its not like im driving it everyday either.
 
I had a 88 Iroc, 89 GTA 305 TPI and this TTA,
I've rode in several Irocs and 3rd gen f-bodys. They still aren't as harsh as Mom's vette. T-tops are gonna make noise. None of the TTA's odd behaviors bother me though cause I know how it feels when she brings on the noise.
So all is forgiven. If it were a new Buick enclave or whatever luxury liner they have then I'd be upset.
 
This is all reassuring to me, just as long as it's suppose to be this way. Those articles all said about the same thing. "rough ride, but all is forgiven once the pedal is mashed down"

As a side bar discussion, concerning PAS's involvement with the conversion. Since spending quality time under the car, I've noticed what looks like extra, or redone welding here and there. Especially in the K-member area. I was wondering if PAS went over these cars and fixed any poor welds and missing spot welds. That may account for the extra rough ride.

?? thoughts??

As a cross related post about pitbull chips and this thread. When I swapped in the factory chip to diganose the fan problem I also realized the car ran much smoother at idle,started with just a blip of the key and not cranking for 2-3 seconds till it fired. AND! the lifter ticking noise seems almost gone too...very strange.

Now I wonder how it will be when I put the TT chip in?

10 times better! I had the stock chip till 2004, then had a casper's 7 postition chip, then got 2 TT chips last spring and summer. My car for years had terrible idle characteristics, it would idle weird and surge and all kinds of weird things. after the chip install all the weirdness went away, it is such a pleasure to drive now.

The Pitbull chip was made by ATR (Applied technologies and research) I have since learned that ATR stands for Absolutely No Technology and No Research:) Any chip will be better than the ATR. TT has been the best so far and I've used the Pitbull, Red Armstrong and Jet performance (GN chip).
 
x2. I also did not like the ATR chip. I did find somebody on one of these message boards who wanted it though. Said his TTA was tuned for it and really liked it. IMO the TT chip is MUCH better but it is good to see when old parts find new homes!
