After seeing a couple cars at this years WOS running motorcycle tires, I have had a hard time getting this out of my head. Clearly my staggered 6.5"/8" wheels with their corresponding 205/235 tires, while great on the street/track, are NOT optimal for the salt. :lol:
So I contacted my buddy who can narrow a set of Porsche wheels for me in hopes of running 17" motorcycle tires and he mentioned that motorcycles use a different bead seat on the wheels/tires. :? Huh?? So how did those of you that ran the motorcycle tires accomplish this on stock rims??
I've got a set of base model Boxster twist wheels that have the perfect offset to the outer rim lip that could be narrowed easily but why bother if tires won't safely mount. . .

We run 15x6 VW Passat steel wheels. We've used 23", 24" and 26" Goodyear Frontrunners up to 220 mph on a 3200 lb. FWD car with ~1000 lb on each drive tire with no issues whatsover.
-
Abe--Make sure you really look at those Frontrunners each time you have run them. I Inspected a pair that came from a front wheel drive turbo car that runs in the 230 range, and they were not nice. Tread chunking, deformation and a case of Driver Shorts Fill....The better bet would be the correct Goodyears if you get the Passat going a bit quicker. By the way--I think I Inspected your car when you first bought it out. Nice Job..

Dewey and Abe run the worlds fastest four cylinder VW, their 2000 Passat. Like Kiwi said, it's nice.

That car is faster than Rick Yacoucci's 'Busa streamliner?

Dan, He said VW :-D

Whoops, you are right John - I read too fast.

When I started my Bonneville build with my 1968 VW Bug, I couldn't find tires rated for the USFRA 130/150 classes. Ended up talking to BJ Burkdoll, the USFRA tech inspector. I'm using Hoosier drag racing front tires on both ends of my car...23" on the front to help drop the front end, and 25" for the rear.
Another racer uses motorcycle tires.
BUT, in both cases we are both using narrow VW rims...4.5".
Don't even think about using wide tires on the salt...Narrow is required/desired/the way to go.

oboy here we go!! :dhorse:

Isn't Das Bullet the fastest 4cyl. VW @ 246.xxx?
Love the Passat, BTW.
-
Thanks for saying that, Fred. I was going to say it -- but thought I'd let you lead the band this time. :evil: :evil:
-
I thought Das Bullet t a powered by Audi? Or are they the same company?

VW/Audi use the same (in Cosgrove's case) 1.8T motor... the only difference in
application use is sometimes Audi will put one in longitudinally for an AWD car...
I've had that motor in cars from each manufacturer; same thing... They can take
an outstanding amount of boost. A friend in upper NY has one sitting at 600awhp
in his 2001 Audi A4 Avant (WAGON)--- Talk about a sleeper!
DW- You guys are running a turbo VR6 in your MMP, right? Another solid motor... :mrgreen:
-

Dan- I was wondering if this sort of name swapping in any way runs afoul of engine swap rules? Same engine but Audi and VW are clearly different critters, a least in some ways. Of course same problem with Honda/Accura and Nissan/Infiniti etc.
-
These are the exact same engine; like Honda/Acura and Nissan/Infiniti, they generally start with the same engine for a given unibody, then may change airbox design, injectors, etc. depending on model and trim... Other than the plastic on top of the 1.8T (now a DI 2.0T), they are all serialized as VAG (VW Audi Group).

Two answers:
Yes we are using the VR6 with turbo, had the record at 189.6 record is now standing at 190.5. We have gone faster w/G class blown 2 liter, 194.5. Lots of potential in the VR6 to take record from the Toyota in F class.
The name difference does not violate the engine swap rule if YOU can prove that is is the same engine w/a different name on the cam cover.
DW
-
Thanks, Dan and Luke. I am aware the basic engines are the same. But there are those- I am not one of them- who might take exception calling it a swap. Especially right after they lost a record :cheers: Just wanted some horses mouth clarification. End of :dhorse: :dhorse: :dhorse:

Indeed, the VR6 has plenty of potential, as do most of the VAG engines. I assume the "Toyota" is a 2JZ?

You can get forged aluminum 17 inch motorcycle wheels from All American Wheels, http://www.allamericanwheel.com/wheels.html, They are 3.5 wide and have a blank center that you can machine to fit your requirements and they are made for motorcycle tires.

I just reread this post. Confused to say the least. Rule 2.F specifically forbids motorcycle tires on cars, especially over 200 MPH. I don't know why these cars have been passed by tech and why are these tires encouraged by 36 HP Challenge?
DW
-
Dan, I think the MC tires they are talking about are the Goodyears 17x3 LSR tires, they are not really MC tires. I think Sparky has them on the front of his Lakester
-
way more people than me!!!!!!!!!! They are Goodyear LSR 400 mph rated tires just happen to mount on MC spec wheels because that's what the dragsters run---
they are triple purpose tires Drag :-D , LSR :-D MC :-D
-
Dan is right about motorcycle tires in the VW 36 HP Challenge.
They are not the 17s.
-
Guess I didn't pay that much attention to the Vdubs.... they have their own set of rules, like the other speed clubs, but I would guess that most of them weigh less than 2 LSR motorcycles :|

hard core chuckle :-D

I can't speak to the topic of motorcycle tires, but I did notice that at least one successful Karmann Ghia was running on Formula Vee tires, which are available in a couple of different diameters (21.5" and 22" at a minimum"
http://www.americanraceronline.com/tires/formula-v-pro-four/
They are legitimate "racing" tires, but I was not able to see a weight rating for them.
