Hio overlooks the fact that now GM is actually gearing their cars worth a damn nowadays after learning from Ford to properly gear a car for its ideal powerband. The old days of gear swaps being one of the first change on pony cars is over.

Gearing combined with more power, less weight (than 5G), and a nice size stall make for a good 60 and good performer.

 

This^ torque =squat, weight transfer etc... lol

 

Are you a physicist?

So you think anti squat can't be built into irs?.....lol.....ok

The reality is why irs works better than sra is all about physics.....you wouldn't understand. And I'm not just talking about drag racing here. Traction in general

 

I agree.....edge would go to 5gen if it was geared as hard as 5br0s. Probably wouldn't even have been a drivers race.

 

Did you read my sig man

 

Yes here on SRK all bone stock 6 gens run high 11s AT THE SLOWEST. And GT500s run high 14s. John Force takes them to 13.90s.

 

95% accurate, except the John Force part is a little much.

 

I like my SRA's for strength, but I do understand what you are getting at, if you have any body roll to one side which usually happens in drag racing. You keep the tires planted squarely on the ground, I guess a sra can through weight transfer apply more pressure to a corner causing 1 tire to squat more and cause uneven pressure across a wide tire on the other side. IIRC that's how I read it a while back in article. It sounded legitimate but who knows. You also have more adjustability but that would be needed with all the flex going on. Maby in the future it will be more common to use it instead of going sra?

Edit the article I was reading was talking about street or bracket cars not pro stocks or funny cars etc. If I can find it I'll post up a link

 

Coming from a mostly JDM country, we have not really had LRA cars for 20-30 years here. Only farm utes etc. Even the Holdens moved to IRS yonks ago.

And we have plenty of near stock suspension IRS cars in the 10s and 9s... I'm shooting for high 10s in my LS3 S2000 when it's done. They're IRS and have run in the 8s. Mine has enough power, it's just skill, tyre, setup and surface are main limitations.

And anti squat and all that jazz is easily done on IRS with active/magnetic suspension.
And that suspension is not really any heavier than normal stuff for a larger car, I have one of the first models from an 09' HSV...

 

It seems that IRS cars bottom out around 8s.....that is pretty good for the average "proto-joe".

 

Lower sprung weight center also helps when you have a light car like that with a big motor.

 

Gt 500's have been known to run 12's

 

And they have been 7s for a hero time?

 

And some low to mid 13's at our track

 

Much like the 14 second LS1 cahs and fif gens at my track

 

They have at our track too.... But what kind of power is that gt500 making again?

All joking aside, that is pretty bad performance for what I've seen some of the run. Some due to bad drivers, some drive the hell out of it. Seems like one out of every 5 run decent and I was quite disappointed the first time I lined up against one, I was hoping for a good run

 

If they made auto gt500's you'd see a lot less of these crap times

 

Very true.

 

Still though for what they are, you see better times out of m6 fbody's that you do out of them as far as power to weight with the times. Meaning I'm not saying the fbody runs a faster trap or et, but for what the cars are, they perform better.

I've honestly seen more consistent, better times out of the new coyote's that run. An auto would run better, but I still don't think it would run how they should for being does top mustang.

 

And see less of them bitching about auto's
