what would win between the three

BLASTER 240 KIT FMF PIPE AND SILENCER

300EX 320 KIT SUPERTRAPP FULL EXHAUST k&N AIRFILTER NO AIR BOX LID

400EX WHITE BROS FULL EXHUAST K&N AIRFILTER NO AIRBOX LID

 

My paycheck would be on the Blaster, just because a properly built 240 will put just over 40 hp to the ground and with it weighing 320lbs has an advantage. Never seen a 300ex with a big bore kit so i'm not sure. Looking at the power to weight ratios the blaster wins easily.


320 lbs 40 hp = 8lbs per hp on the blaster
377lbs 30 hp = 12.3 lbs per hp on the 400ex
380lbs 27 hp = 14lbs per hp on the 300ex

but thats just guessing on the 300 ex

So I dunno, depends on gearing and stuff like that. Looks like blaster all the way.

 

the blaster has about 16rwhp stock I highly doubt a 240 kit is going to add 24+ hp because my friends 240 blaster still can't keep up with my friends stock raptor.

 

I would put my money on the 400, if the rider knows what he is doing.

 

There are alot of places that claim a 240 blaster makes 40hp. Given its not just throw this piston and cylinder on your bone stock blaster and you have 40 hp.

If you had that kit with mild port work, a bigger carb, aftermarket reeds, air filter, and aftermarket exhaust and a few other little things it's totally possible.

Most of the stuff I mentioned above is part of the usual 240 kit.

Consider that a 250r with just mild mods can make 40-50 hp its entirely possible.

One more thing, stock raptors are extremely anemic.

Modified are fun!

At Haspin Acres some kid had a 240 blaster that was eating piped banshees, 250r's, all 400's, predators and most every raptor.

Took a beefy 370 long rod banshee and a built raptor to even beat the kid. YZ426f put a hurt on him too.

Light weight and big power = fast


It takes a Yamaha to beat a Yamaha

 

I'd take the 400EX most of the time - but agree if the Blaster was built just right it could pull it off.

 

If the blaster has a real 240 cylinder kit, it will blow away a 400ex and a 320ex. Blasters are not to be taken lightly when they have an aftermarket cylinder and a 35mm carb. If the blaster just has a 240 sleeve, the 400 would win the race.

 

400 250 320 in that order

 

Tell ya what, I just put my kid's Blaster together, a stock bore with wiseco piston, ported & head mod by Eric Gorr, FMF pipe, reeds, aftermarket air filter, jetted properly etc. That little thing rips. I would not be surprised if a properly set up 240 with carb to flow enough air would eat up a piped 400EX. Heck our stock bore Blaster would be close if not pull it out.

 

well the reason i was asking was cause we went ridin today!drag racing my 300ex won but by about 1/4 length to the 400ex.and the blaster was right behind about 1 length we draged on a gravel road and a concrete road
