I think you are going to be surprised with how fast people are going to go with the rules the way they are!

This will be run on the 3rd Saturday of the month correct?

Probably no big chiefs or canted valve small block stuff.
 
#25 ·
So is a canted valve head allowed. At least on a small block N/A motor.
I don't wanna spray but wanna run in radial and I know I can't keep up with the outlaw radial guys N/A But I will try.

Don't think I can stretch a 275 on the beadlocks though.

We will have to see. The 295's just barely fit on them with the 6inch BS.

Just talked to Dave-Yes a canted valve is OK for a SB, He was saying"conventional head"only for BB's.

This is gonna be fun!!!!!!!!:-D:-D:-D

I just don't see a 76mm turbo car keeping up with an F1R or a 400+ inch small block on 2 kits. F1R cars will be in the 20's,nitrous cars might be in the teens,and a 76mm is gonna go 50's if the combo is built for a turbo that small.
 
#32 ·
If you run a small block with one kit instead of two will you still have to weigh in at the 3100lbs.

Still kicking around the idea of trying to get 275's on it.

Then we can run our Outlaw 10.5 car on the first Saturday and the radial 275 class on the third saturday.

Thanks Dan Smith

Looks pretty good to me. Was talking to a few racers that inquired if maybe a larger turbo could fall in at a heavier weight (say an 88MM at 3400lbs.)?
If that's the case, then why not let the guys with BBC w/ XX-trim and Pontiacs w/ F-2's in at 3450lbs? Ya gotta stop somewhere. I don't like it because my stuff is not a max effort, but we all know how it goes and someone will come into the class with cubic dollars backing them and kill the class with either combo...more than likely a BBC! LOL:)

the rules gotta go 1 way or the other if a f1r is not allowed the f1 wont run with a ysi or x so they cant be allowed gotta decide if you want a 5.20 or 30 class or a 5.60 or 70 class i just wanna race
 
#47 ·
ok didnt know fratena stepped up hi turbo the nos rules aint the problem everyone is complaining about the f1r but the ysi is ok a regular f1 will not run with a ysi period like i said just wanna support you guys and come run i have 3 cars legal to race so lets just race
 
#49 ·
I'm with ya let's just race and as the rules state things are subject to change at the discretion of the track officials
