And back on subject, the real 944 GTR made ~525rwhp and blew the competition out of the water in the 80's.

Now that we live in the 2010's you can get a Z06 and make that much power with a mild cam and an exhaust, or upgrade to a ZR1 for another 100hp in stock trim.

I'm not saying there weren't high powered cars at the time, i'm just saying the competition back then was a lot different than it is now.

Without doubt...however as we also know, it's not just the ponies that get you round the track the fastest.

For sure.

minho78

Absolutely. Actually making 1500 hp out of the 5.0 engines if I,m not mistaken.

Yeah... but the only thing in the car that was Porsche was the engine. The block and head weren't production pieces either and neither was the crank, rods, or pistons, intake, exhaust, or turbo. I think the valve cover was the only production piece I can think of and even it was modified.

The car was a tube frame hand built race car that had body panels that looked 944. That's about as much 944 as it was.

I am not trying to come as a jerk here but you guys realize we are not talking about a original GTR nor a replica, it's a 944 turbo who some Germans decided to name GTR for unknown reasons it's has the original body and it looks a bit stockishhh.

Turbo is an modified K27/9 with 23 PSI Boost, no Overboost, we still run 23 PSI and the Turbo hold it up to 7400 rpm !!! Fuel is Standard 98 ROZ, The ECU is an modified 968 with an Extern Manifold Air pressure unit. but we can also use now an Stock ECU with an 997 Turbo Pressure Unit !! we will do this with my Engine, in my Street Car. Same Engine, same Turbo :-D

The Gearbox is an Manual 6-Speed, with 1st and 2nd Gear are Stock 968 Turbo RS and 3rd, 4th, 5th and 6th Gear are straight teeth with Top Speed in 6th Gear 265 KM/H @ 7400 rpm.

No it's not the original factory GTR, here is a video from the rear cam

That's closer to your car than a 944.

Bit confused about this? I guess he means he's got RS 1st & 2nd and then some short ratio straight cuts. Bringing top speed down to only 265kmh is a huge drop from the RS gearing which at 7400rpm would be approx 320kmh. As some of us have wondered on gearing for bigger bore turbo cars, this sure makes an argument for closer ratio working well for a blown motor as well as the traditional close ratio n/a race cars. Shifting is quick with the straight cuts too.

The GTR wasn't built by Porsche. And it's not built on a Porsche tub. There is literally zero on the car that's Porsche except some of the engine (and of that... none of it was production pieces).

The GTR's were hand built race cars that had a body that resembled a 944. That's it.

And if there were to race today... they would be automatically put in the fastest class because of their tube frame. That puts them against 997 RSR's and a bunch of other very expensive company. How would they do? Probably very well since their suspension isn't based off of a 944 and the car, and being a tube frame car, is very light and very stiff. I'd love to own one...but not at $215k.

My car, conversely, is based of of a 944 tub and in fact uses all Porsche suspension, brakes, trans (yes.. made by Audi... but it's the same trans that came in a 944). That's a huge difference.

The only thing on my car that's not Porsche is the engine. And that's just temporary as I fully intend to install a Panamera 2013 V6 Twin Turbo. At that point, the car will be a full true Porsche.

Yes, but a Porsche what? lol. Your car will need it's own unique model number!

From what I can see in the video, this is not a real 944 GTR. The dash appears to be a stock 951 dash - nothing like the real GTR. I suspect that the car in the video is a heavily modified 951 - nothing more.

I have a friend who owns one of the 7 GTR's made. His is chassis number 5 and it has significant race history. I was fortunate to drive his car at Willow Springs race track some years ago - an awesome experience.

Some photos attached show the car and the interior.

Slivel, did you bother to read post 67? Iam pretty sure most of the guys here knew it wasn't a factory GTR, but the point is that the car in question is an example of a well built 951

slivel

Guilty.
