True, that car has long owned the record and agreed it deserves it. Period. Nice job, very impressive. At that time I remember what that white car meant in my mind, and that has drastically changed from forefront of 928 development to but one of many. There are MANY other good reasons for this too and I refuse for the time being to get into that, but I have nothing against the white car.

Is it the fastest 928 on the planet? Not.

I'd say that today the margin has shrunk incredibly. For instance, could one of Mark, Joseph or Marc or Mark's race cars stand up to Shane or Tony's cars? Certainly. How about Rob's (is it 550RWHP?) BEAST .... Somehow I think in a straight line, on the Salt Flats ... no bloody chance.

Will we ever know? If it were up to Mark Anderson, I would bet money he'd say "sure let's do it, sounds like fun".

Sorry, but not everyone can have a brother that's intelligent and good looking.

Carl,

At least with Michael Jordan you could make comparisons of him playing the same game, on the same court as many, many other players. It's very easy to win or claim to be the best at something if you're the only one competeing. I mean I could accurately call myself the greatest basketball player of all time if I was the only one who ever played it. How many 928s besides Marc's have ever attempted to get an official speed measurement of 200+mph? I was hoping that Marc would be at Road America when a number of 928 racers, including Mark Anderson, Joseph Fan, Don Hanson, and others were there from across the country to make some comparisons, but he wasn't there. I mean a lot more 928s participate in track events than any sort of documented top speed event, so it would seem like a much more realistic comparison could be made to how a lot more 928 owners actually drive their car. Maybe Marc could post some of his track times so that we could compare them to other 928s that have been on those same tracks?

Heinrich,

Cars like Mark's or, Joseph's would not be able to go that fast because of the gearing that they currently have. They each have more than enough horsepower to go more than 210mph, but with the gearing that they have in their cars they'd just be bouncing off the rev limiter before they got to that speed, no matter how much power they had. The same goes for George's supercharged car, and Marc is well aware of that. He's also well aware that in order for a car to be able to compete in any sort of offical event that would document a speed that high it would have to have a number of safety modifications that would require cutting and drilling of the car, previous event experience, and a special license for the driver. If cars geared like Mark's or Joseph's had a higher rev limit, they still might not be able to go that fast with their current gearing because their engines might not be capable of reving high enough to get to that mph speed. The high piston speeds that all stroker motors have will limit the maximum RPM that they can go before they blow up to lower than the RPM that a similarly built engine with a shorter stroke, and the lower piston speeds that result from that shorter stroke, could go to.

If anybody wants to see what sort of a top speed a 928 properly geared for top speed should have based on it's horsepower, there's a calcultator at:

Aerodynamic drag calculator

For an S4, the drag coefficient is .34 and the frontal area is 22 sq ft. Those are the values without the mirrors being removed and the car taped up to reduce drag, like Marc's was.

Gosh, if only there was a 928 engine with much higher power than Marc's when he did his 200+mph, with a shorter stroke and higher RPM capabilty than his engine, and also with gearing that would be even more suitable for even higher speeds than just that. I wonder where somebody would find a car like that?

John..

Tim, I respect what you have done, but please get us some real performance numbers on your car. Until we see this, Andy has the quickest documented boosted 928 out there. Big deal, a dyno run is just that, a dyno run. To me that is talk, and talk is cheap. There are variances between dynojets and I have said all along, they don't load the car like the road does. You guys keep quoting peak HP numbers over the last 400 RPM, but how long does your tach stay at the redline? Not very long.

You call my claims "unsubstantiated"...take a good look at that graph one more time....350+ft-lbs on just 8 lbs of boost Tim. 4.5 liters, no trick cams, just a M28.15 with good pistons. And that run was with 2 degrees of timing out of it with a bad fuel mixture...that same 2 degrees added 20 HP on the 12 lb pull. Everybody has seen the photos of the Goldmember's engine and you all know I am not BSing on this. The manifolds are getting fixtured this week to allow for reproduction. However, there is one thing that is unsubstantiated, that is how big of an ***-chewing the TT car gives to the equal CS car on the track or street. The other unsubstantiated claim is how fast a Super Shark actually is....prove it to us and we shut our pie holes. I don't care if it is a Civic or a Ferrari, the same rules apply and superior technology will always win. Mercedes, Saab, Porsche, Audi, VW and the rest use this superior technology today. My goal was to integrate it into the 928 with good results, which I have done. For the record the Bastard squeezed off a 5.4 second 0-60 and a 13.6 @110+ MPH 1/4 mile before I ever touched the engine. Should I send my G-Tech up there so you guys can use it?

Isn't it great, we are all getting along just like we used to. If you ask me, we all need to get a life.

bcdavis

No way!

I want you to be pestered into doing a TT s4!

Hahahaha!

But I also would like to see your goldmember OB up against Carl's CS OB...

Until you have a TT s4 that we can put against Tim and Marc and Andy...

Fastest928

Tony,
Mark A or Joe F 928 might get to over 200 mph, and, might not for a number for reasons. The largest being the fact that Mark A "928" is about 1.5-2" wider than a stock bodied 928, and J fans is way toooo wide.

There are no SC vehicles in the 200 mph club in ORR...yet. For a reason. running these races is not like running on the salt flats, or the dyno...the vehicle must remain capable for the "whole" event and maintain speed....and some of those events are 130 miles with radar traps positioned in various spots....not as easy as one might think.

Realisticly, having another 928 on the 200 mph board is a excellent goal, and acheivable.

Rob, you get it! And the best part is for the next 50-60K miles, the only thing to do is change the oil and enjoy the feeling of hammer it whenever and it is not going to break, only applicable for street tires. Oh, plus the improved fuel economy with be a big plus these days!

Thanks for the thought but the problem exists with the oil cooler being under the radiator on the 90+MY cars. I have instructions on modifying the belly pan support which gives the room for unrestricted intake plumbing. Pretty simple acutally, but then again, it all looks pretty simple after you have it figured it out.

Old & New

BlownBeast's setup, then...

Tim Murphy

He has a very nice setup, but it is not cost effectve for a kit. If someone wanted to do that to their car they could and I'm sure Rob would help them out. Not an easy job though.

We got the air routing figured out, proven on 3 cars already, and it's easy.

I am running 14psi with the same setup so I know it works.

Thanks for the ideas though.
