So you're saying I can run over fenders to fit the tire?

[evil8]

Throw together whatever you want Dave.

[DOZZER]

Count me in for this. Pm me more info. Thanks.

[evil8]

What info do you want?

[DavidBaustert]

Whats the average times for these classes?

[Mattsv8]

If the payout is thereand a track preped for 275. Then at a min 5.0 to be competitive. But if there's no payouts I can't see many doing it for long. Id have to guess a competitive 275 car will run upwards of 60000 and I'm shure there are more expensive ones than this. Its a damn tuff class ask ray about what he's spending and ets expected. He would be the closest to it on this forum to ask.

[DavidBaustert]

Yah I'm out. lol. Is one of these classes good for a ~10sec car?

Those are 1/8 mile times.....

[TurboNova]

No e85=gay

[rl]

Why no E85?

[schmuckingham]

I really need to learn drag racing classes better all this talk of x275 makes me thing I am reading a drug manual

[evil8]

Any 10 second quarter mile cars are gonna be back markers even in the Limited 8.5 field.

This has been beat to death.

John Sears's answer is it is to hard to test, and he tries to make as few changes as possible.

My take on it is VP is to large of a sponsor to cross.

I loved and ran the ethanol for years, It killed me to spend $780 for a barrel of c16 last year. After running it and looking at the big picture I found my car makes more power with gas. The difference in fuel is almost covered by the smaller fuel system that is needed. The amount I spend on fuel is NOTHING compaired to the costs of fielding a car that is competitive in this class. At the Ducks race in Georgia the bump was 5.01 on a 32 car field.

I would expect anybody that could run a 5.30 to go rounds and have a shot at winning depending on who shows up. Remember in these little tire classes people dont get down the track alot.

Piss. I'll let the big boys play in this one then :-)

[DOZZER]

What info do you want?

I found what I was looking for. Thanks.

[Mattsv8]

Why no E85?

 

cause the shits that good its treated like methanol. evan thought its only 30 percent more fuel not double.

[TurboNova]

With those rules here in the area I bet they don't field that many cars.

If the only thing stopping you is the E-85 issue then petition for a rules change. If you really want to be effective find another in the same position and commit to coming to the races. Nobody will look at a rule change for one person that may or may not show up.

[99BlownYellowGT]

How many of these cars are in this area and are going to want to come there...i hope it works out id like to see it

[Mattsv8]

i think its going to come down to payout and the track. if kilkare will actually prep the track to what a x275 tire and 8.5" slick need then id say a few will show up. rest is up to the payout. nobody will spend 60k to race this class if the payout sucks.

[Mattsv8]

Here is a thread on yellow bullet about a lil v6 s10 with leafs. Check the et and mph u better have big wallets guys.

i guess I will, I am not going to spend 19 bucks a gallon for fuel when I can make the same or more power on 3 dollar e85 and drive the car to the track.

 

wish nhra was not gay and wasn't in bed with vp fuels

[Mattsv8]

Racing for the most part sucks. We all wana go fast but u have to be big budget to evan compete in a lower level bs class. The payouts aren't ever enuf to coer the cost of feilding a car and wanting to be competitive. If your like most racers your budget don't allow much but if you wana run in a class for money then u better double ur budget. I've never competed in the s10 outside of some weekend brackets cause I simply can't afford to be competitive. I love heads up racing but my truck dosent fit in a single class except nmca open comp maybe. Or just bs weekend brackets. So all that's left is to build a car for fun and enjoy it. I will deff come see the racing and will proably make a few in the s10 but not in any class just tnt.!

[TurboNova]

yeah same here I did not build my car for class racing, and I could care less about winning money racing. I just wish the rules would be simple for some class racing. It sucks when your car fits into 90% of the class and then there is something stupid that holds you back.
