What gives with this post, it is now 2 day old, and keeps coming up as a new post, but when you go to it it comes up the same old post, just sayin! Post # 60, right above my latest! Bob

No matter what you do the guy with more resources wull always be faster... If people would stop whining about national motors and did some research instead they could build a killer ecotec for under $10k... I know of an ecotec in California making 350 hp and the guy has under 10k in it...

LE, what I don't understand is why Jims post has preceded it for 2 days, and, it does seem odd, that any one just wondering by, could "vote" on something they have no investment in, looks like they take more interest in something like this, than who in the hell is going to be our next President, or POTUS if that fits better, again, beats me! Bob

Just messing with you. Every time somebody votes or changes their vote the thing goes back to the top. It seems to be pretty legit poll so far. People are voting basically to keep these things pretty low budget, and close to stock and that is a good thing. The things that stand out is the large percent that voted for HD valve springs vs bigger valve and the same holds true with HD rods vs high comp aftermarket pistons. They seem to be voting for lower cost vs deep pockets.



The DII people are putting forth an effort with racing groups such as the BMARA. I also understand PowerI will have groups in several states for this coming season. This should be a good year for Midget racing. I hear that they are planing a few indoor shows at Duquoin already.

Sure wish I was younger>>nothing fun about this Old Age Stuff.

LRP


350 HP won't make it but to about 5th place or so in National Midgets now days.

And then you got to ask your self does that rich man also hire the best drivers out there or is his kid doing the driving for him?

There is no midget motor making over 375-380 hp... It is impossible to do on straight methanol... There is a formula for per cubic inch how much methanol will make hp... I forget the name of it but all these guys says they have a 400 hp motor there is three things either it is "big" or whatever dyno it was ran on isnt reading true numbers or they are putting some stuff in the fuel

Here is a link to some charts for injector sizing.

https://www.injector.com/injector_selection_guide.html

We use 4 x 60 pound injectors in our 1000cc mini sprints making around 200 HP and back them up with 4 x 30 pound shower injectors to help cool the charge down a little.

For a 4 cylinder motor shooting for 400HP would require 4 x 150 pound per hour injectors.

The problem is not getting enough fuel in there>>>> the problem is getting enough air in there to burn the fuel. That is why intake valves and ports keep getting bigger and bigger. To the point they have to spread out the bores center and increase piston size to accommodate even larger intake valve. Essslinger raised their ports to get better air flow but they got stuck on valve size.

Now back to these little four valve heads. They flow much much better than a single valve cylinder head thus more horsepower is available. That is the reason we can get so much power out of the motorcycle motors. If we could put 2.6 motorcycle motors in a midget we would have 520 Horsepower on hand.

what i know of the new badger rule is you are not allowed to port and polish the head. you can buy after market parts like valves, springs, cams, rods and pistons. no titanium.

Would you please read the rule book for the BMARA before commenting on their rules. All you do is embarrass yourself and spread incorrect information.
