It seems odd to me that a Trans Am would be slower than a Porsche on the straights, yet faster through the corners. That 935 has crazy aero, I am betting at least 10 times the downforce of the T/A. Seems to me like a case of too much Porsche for the driver...
Still a really cool T/A, but I would MUCH rather have the 935 K3...
Oh, and to answer your question....ALOT!
Vintage racing is rarely about which is the fastest car.
That T/A has almost nothing in common with a real Trans Am car...

What do you mean? It's a replica of the car Jerry Titus drove in the 1971 Trans Am series.
I don't think the Porsche was faster on the straights, it just put the power down better getting out of corners, which is the whole point of the rear-engine layout.
If my transmission sounded like the Camaro's, I'd head straight to the shop! Straight cut gears and a big BANG every shift is weird.
No one wants to consider that the Porsche lost power (or had other mechanical problems) that allowed the T/A to go by so easily?
Under normal circumstances, a 935 will turn faster laps than a Trans-Am car built to a five-years-older, more restrictive ruleset. Which is exactly what the video shows right up until the Poncho went by the Porsche.

Nitpicky, but it was a Pontiac Trans Am, not a Camaro.
I also think the Porsche lacked a qualified driver. He looked squirrely on the brakes, twitchy, and almost nailed the TA coming out of a corner. TA tranny sounded weird, any ideas about that?
The P-car was killing the T/A down that exact straight. The pass was obviously the P-car driver letting the T/A by, or having issues. Love the T/A, though!
The owner of the Trans Am occasionally posts over on the Performance Years Pontiac board - it's a killer car.

That was pretty much normal behaviour for a 935, regardless of who was/is behind the wheel.

I remember reading that at least some of the 935's had spools instead of differentials. This made them a hop around a lot in tighter corners. I could be wrong.

It was in a recent issue of Excellence. 934 Vs. 935 at Laguna Seca. April 2011 issue.
Johannes Van Overbeek and George Follmer drive them around for a day. God, what I wouldn't give for that opportunity!

That's correct. I believe they used a 930 4 speed transaxle which was mounted upside down. The 935 put out 750hp normally and they could crank up the boost for qualifying, so there is no way that trans am was getting past him unless he had a problem.

No, it's not. It vaguely resembles Titus' T/A. In 71 flares were not allowed. Neither were wheels that wide. Or dog boxes. Or engines larger than 305ci. That car is a no-rules almost-a-GT1 car with a historic paint scheme.

If you scroll down a little on the page in this link, you see a pic of his '71, and it has flares on it. Maybe the pic description is incorrect, but nevertheless, the car resembles Titus' '70 Trans Am. Maybe they just got the year wrong. And where did it say the engine size? I know it's unlikely that they got 700hp out of a 305, but I also didn't see where the engine was not a 305.
Edit - The link must have the year wrong, as he did die in 1970. But I still say the tribute car looks a lot like his '70 T/A. They didn't say it was identical, just a tribute. In any case, I think it's a cool car.
Edit 2 - I looked the car up, and it has a Butler all aluminum 496 Pontiac in it. That's okay in my book.

Speaking of which, Jerry Titus died in 1970.

BIG difference between a 305 and a 496! Like I said, it's not a Trans Am car at all. It's a GT1-style car with a T/A body and historic paint scheme. Way cool, but so not a Trans Am.
Also, the "research" link was crap. Forza forums where they claim GT-1 'Vette's raced in T/A? 
Real resources:

The Titus 70 T/A today:
Notice how small the flares are. Another shot:
sounds like a spaceship.
I think we're picking nits, here, Jav. All I was saying is that it is a tribute to the original. My definition of a tribute is something that is based, maybe loosely, on the original. Otherwise it would be recreation or clone or....
It looks a lot like Titus's car, IMO. The fact that it has a different engine doesn't really bother me, because I don't think it was intended to be an identical copy of his car. But whatever.

How would you respond if someone said Michael Pinto is a god?
