Seeing as a 1/4 heat soaks the engine, would it affect the aerodynamics to do the runs w/o a hood? and would it help at all with the wind on the s/c? usually aerodynamics are important around what, like 100+? and only doing 115-125 mph tops a run wheres the real loss?

i think this will be a positive -- you will gain in cooling -- and you can set up a simple RAM air setup by removing the snorkels ---

You could lose a tad in aero and looks-- but you will also gain in weigh reduction --

So - that is 2 big pluses in the performance area -- maybe the slightest negative for wind drag -- and a minus for not looking so good --

Also - a big plus in sound because that Supercharger will whine like crazy.

would nhra rules allow it?

skratch77

does anyone know the 2011 rules for when you need a cage?

AKnight55

12.5 @ NED I believe

skratch77

Has it been posted officially anywhere?

AKnight55

The following infractions shall result in immediate disqualificatin and competitiors shall not be permitted to race until the discrepancy is corrected:

Convertible running 13.49 or quicker without a roll bar
Motorcycle or snowmobile riders running 10.99 or quicker without leather pants and/or a lanyard
Hardtop vehicles running 11.49 or quicker without a roll bar
Drivers/riders running 9.99 seconds or quicker without a valid IHRA credential
Drivers running 13.99 seconds or quicker without a helmet meeting Snell or SFI specifications
Drivers/riders running 13.99 seconds or quicker with a co-drive

This was taken directly from NEDs site.. I thought I had read 12.5, but it seems to be 11.5...??

I just went threw the pdf manual also and no where does it say 12.5 needing a roll cage.I heard this rumor a few times and was worried that most cars would get kicked out.ill be there april second

Sacto you could drag while having sex with the ole lady, but that's the freak show known as Sacto

wouldnt the steel tubing that comes with the E55 count as a roll cage?? maybe just ad a 5 point harness and youd think thatd be enough in the all mighty life saving 55

Umm,no

Limen

Wow....very strict!!

skratch77

not really nhra has been like this for years,there was a stupid rumor saying anycar under 12.5 needed a roll bar.

They usually let you slide with a few 11-11.3 passes without a bar and if its a busy night they wont even notice.

In a word, NO.
At least not at these speeds my friend.

DRAG FORCE ON A ONE-SQUARE FOOT SQUARE PLATE

Speed

0 mph 0 pounds 0 hp
100 mph 33 pounds 9 hp
200 mph 133 pounds 71 hp
300 mph 299 pounds 239 hp



Basically, areo dynamics do not mean much below 150MPH. A quick history lesson is from NASCAR when they would trade hoods and front fenders on the super-speedways and still win. Talk about drag

Thats 2007 they have new rules every year

E55Bullet

Someone needs to make us a rollbar.

pearlpower

There go my hopes of having a race snowmobile.

AKnight55

Ha you joke, but not up here in the Northeast.. I know people who take their sleds to the track lolll

118E63

Yup&Ive seen plenty at Englishtown running 8's in the 1/4

LOCO 05' E55

I've seen a 55 with a removable roll cage in it, but seriously if you can get your fastest passes at a track rental why go and slaughter our cars even more just to be allowed to run below 11.49 as much as i like drag racing, no more test and tunes for me..And i was planning to make a NED appearance this summer but with those new rules no way

AKnight55

Damn, would have been sick to see a 55 make a ten second pass.. Maybe skratch will get into the tens this year though, before he gets kicked out haha

03'55AMG

E55s have already achieved 10's
