426 and 440 time's at the track

[400exshop]

Some of you guy's ask me to post a up date on the 426 and 440 time's at the track, 1/8 mile.

Befor some of you guy's read to fare and start in on me or report me... Stop reading now, so that you all dont start any prob's.....

For the guy's that ask for the up date's, We went to the track to day with the 426 and 440.

The 426 went 7.93 at 80.50 mph, The 440 went 8.10 at 78.89mph .

426 set up is 11.1.0 comp, stage 2 hot cam, p&p head, 450fcr carb, monster drag pipe's, 16/34 gearing.

440 is 12.5.1 comp hmf full pipe with out cap or packing, 450 fcr carb, p&p head stage 3 hot cam, 16/32 gearing.

we do have nos on both bike, but the nos was not working right. We will pull the jets out to see what was going on.

If we get the nos to work like it did last year with the numbers we got to day, We will be the first to ever make a 400ex go in the 6's in the 1/8 mile.

As of right now we have not found any one that has gone faster then a 7.80 other then us with the 7.20..... Looking for the 6's , If we pull it off we will contact the Gennis Book of World record's to see if we can get our name in there....

sounds awesome man! them things go pretty good eh.

[bryan1984]

Just curious but why do you think the 440 was the slower of the 2?

[Thumpin440ex]

Thats pretty damn good. I would like to see the 440 bike geared the same as the 26 bike.

If you put the packing and endcap back on the hmf itll probably be even better

I don't know why people should be upset with you sharing your times .
As long as you don't try to turn this into a drag forum .I personally like to see what you can do with your bikes .
It's not my cup of tea but I find it interesting.

P.S. Good luck on the world record attempt.

Not true, 4 strokes gain power and speed with the more air flow you give them. Thats why drag cars and drag bikes all use straight pipes or only headers.

I remember 400exshop thought the same thing until he went to the dyno and pulled his slipon off and gained some HP.

lol it wasn't a slip-on it was the can,,,,, hahaha but you are right we gain hp on the built bike, when we pull'd the can off.

So that's why we gutted the can,,,, ill post pick later, the 426 is lighter.

[Thumpin440ex]

Whats diff on the 26 bike to make it lighter?

Just because its made from Chrome moly doesn't always mean its lighter in weight.

If you take the same wall thickness DOM tubing and Chrome Moly The weight difference is virtually zero. Chrome Moly is stronger and allows you to run a thinner wall thickness and still have the strength of a thicker piece of DOM, thats where you save the weight.

By going to the set we have now, we save 25 lbs just on the front. Then we took the oil tank off of the bike, that alone ( as in the oil tank and tank kooler, line's - the oil that the tank holds ) was another 10 lbs we took off the bike. So that is a saving's of 35 lbs off the bike. We built our own drag steam and gutted the fram. All and all we took off around 60 or a lil more off the bike.

where can I find some spindles and a-arms like that?

[400exshop]

I built them in my shop. the out of fram drag pipe are for a 700 Raptor. With the right tools and a lil know how you can do what ever you set your mind to.....

If you look at the other pic's you will see we are doing the same to the Raptor. There are other pic's if you look to the right it has names of other file's.
