New ProStock rules

Looks like the 4 valve heads are legal for all cc's again plus you can build a current on the showroom floor dragbike with fuel injection. I guess we can say good bye to the old GS platform. With any luck maybe some of those out date parts will make there way down here at rock bottom prices.
 
I would have guessed they were running all custom stuff based around the Busa by now. I don't really follow NHRA. But hope your right!
 
Oh Ya! I hope they all switch over and flood ebay with all sorts of goodies.

Ive noticed alot of the racing efforts already have a Busa based bike waiting in the wings ready to go.
 
I wonder how well a plain bearing crank would hold up to prostock abuse. I've heard alot of guys who build big high horsepower busa motors wipe the bearings out. the roller crank has an advantage.
 
I guess we can thank those's HarlyDavidsons for this rule change :-k 3 years in a roll :lol:

Maybe they'll put a roller crank in Busa?? Just do all the mods and one offs and get JMC to give you part number and your legal.

Just a few weeks ago I look at a friend Bandit cases's and freak out at the size of the main bearings. Then I remember they don't have roller cranks but boy did they look small.
 
I just read about the new rules. Can you say an all 6 second field. You can make way more power with a 4 valve head than a 2 valve head. Should make for an interesting year.
 
I'm not so sure that the GS platform is going to go away because of these rules. What it might do is make it hard for us to find good 4-valve heads. The fuel injection stuff will be a wash I believe...I'm not so sure that it will really give a HP advantage. At the displacements and RPM ranges these motors run at, it's a matter of how much fuel you can dump, not meter, into the cylinders for max HP. If they have an advantage it will be in atomization of the fuel. That roller bearing bottom end on the KZ Kawasakis and GS Suzukis will be hard to beat.

Then again, there are Pro Street Hondas (Kent Stotz's for example, which has run 7.27 @202MPH) that are putting out HP numbers that are not that far off from the Pro Stock numbers and they are using plain bearings.


Actually this should be a good thing...put the "Stock" back into Pro Stock. Now they need to get rid of motorcycles with motors that are designed specifically for the Pro Stock Class (*cough* Harley V-Rod *cough*).


Hap
 
Forgetting about what the top of the engine is & size advantage given to the HD croud IF the HD guys had to use
stock lower end they would never make a complete pass
 
I wouldn't have guessed that anyone ran a stock bottom end in any PS bike. I would think that even the old Suzuki used a lot of billet parts in the transmission, clutch, crank, after market rods, stronger bearings, etc. I figured the new Suzukis ran all billet cranks plus the other stuff. I really have no idea.

I bet they used to use the stock GS cases though....

Anyone watch that last eBay head go over $400. I paid $250 for my last one. Prices seem to be going the wrong way.
 
There's a 1100 head with 31 intakes that look like they could touch each other. No times on the head so who knows what it would run??
 
All they got to do is make all the bikes the same cc's and put them all on the rev-limit say 8K too, then it would be fair to the HD's :-({|= then again maybe in a few years they'll have the BOT (bike of tormorrow) like NASCAR

heck maybe I can get a roller crank in my Sporty and run them numbers too

LOL!! I don't know anyone who wanted to see Theyoda or the standard car. I never cared for IROC.

Was looking for a second 1150 head. I still havn't sent out my 1100 head. Was holding off to see if one would show up. Just wanted it for the strength, not the bigger valves.

Bump goes to a record 7.05? Hector Arana

11 bikes in the 6 second range............
 
Finally read the article on db.com. I had no idea they were still running these old heaps. They talk about 20 years old but I was thinking with the 2 valves, it was going back a bit further. Very insightful.

I'm 2 seconds off the pace and shy 50MPH. Put's what the pro's do into perspective.

BTW, u get the clutch info I sent? Let me know if u need weight numbers.
 
Crap I can't remember what the rule was before but was it 80 cu. in. for the 4 valve heads and 101 for the 2 valve and now they are the same? The weights are all the same but the H.D.'s get 160 cu. in.?
 
Quickest field ever......
GT Tonglet bumps in with a 7.04.
Karen stoffer bumps in with a 7.033
steve johnson current bump with a 7.046
Steve Johnson runs a 7.002
Karen on the bump with a 7.033, GT gets bumped out, Looks like the field is set.

Crazy. So close to a 6 second field. Awesome to listen to. Looking forward to a very exciting season.
