In my opinion there will be no LSX cars there again this years. The rules 100% do not favor or even compare to the honda rules... You can not run with the all motor honda guys under the rules. COULD the LSX rules run in the 9.7 range the honda guys run? Sure but 1 MAYBE 2 cars can run those numbers that i know of being 100% legal.

You're very likely correct, Fran. But if we don't show, Jason won't know.
If we get 4-5 LS powered cars and the quickest one goes 9.9s, he'll see we need more help next year.
I figure, it's a start. At least he's doing something to help us be competitive.

I tend to agree, 2 years ago I raced this event with my gto. With my cubes I could only run my d1dc p/c....car was basically well wihin the rules....the imports in the same class were gutted race cars with 2 power adders running low 8's. I respect this event(been going to it since it started) and all the hard work put into it, however I would have had to of made over 1000rwhp to compete with the imports(et wise) in the class. Not gonna happen with a stock headed ls1/ d1sc lol full weight 'street car" as this was supposed to be.

Looks like Jason is trying to help the LS cars out to me, hell some combos got 300lbs taken off of them.
You cant expect the rule makers to write the rules for street cars, what happens when a well thought out race car shows up under those same rules?
Been there done that with racing my street car and its very hard to be competitive.
See everyone there !

And I'm 250lbs... but I agree its insane... lol
If you cant get light you need to make more power.
Build bigger motor?
I would say get as light as you can and run as fast as you can this year.
Jason seems to be pretty good about making changes to get racers what they need to be competitive.
Just wondering what you think needs to be different rule wise?

Ill be racing street fighter but still... Yes jason is a great dude and does do good with rule changes
I was trying to think og how you can limit how fast they go if you allow someone to build an engine... Compression for sure would have to be one of them. Or maybe a max compression for certain cubic inch maybe. Like 347 is allowed 13:1 but a 427 is allowed 11:1
