I am not biased in this comparsion, I have owned, and do own both of the afore mentioned quads, so here goes. My Raptor was set up with complete Big Gun exhaust, Pro design filter kit, JTM +4.5 swingarm extension and a 14 tooth front, at the time it would run 81 mph at 14.66 in the quarter mile. 89 Zilla, bone stock down to the air filter, pipe, carb, ext, stock gearing, but with a new clutch. race was run on asphalt, this eliminates tirespin and gives a more acurate comparison than dirt or sand. As anyone with a piped Raptor knows all to well it is almost impossiable to keep the front end down on any surface that gives any traction, the swingarm extension allowed me to dump the clutch and spin the back tires,while keeping the front end down, the Zilla will spin because of the nature of the 2-stroke, and the greater front end weight. After about 5 races, switching riders, holding my mouth different, ect, the results were always the same. Both quads would leave equally out of the hole, the Zilla would put about 6 bike lengths on the Raptor through the gears, but after the bikes topped out they were running almost identical MPH, this was confermed when the stock Zilla ran a 14.34 at 80 mph at the drag strip, so the Zilla is quicker, not necesseraly faster. We did numerous test, 1st gear roll on, in which the Zilla murdered the Raptor, and 5th gear roll on where both bikes hung right beside each other, so In summary, a piped Raptor will not out accelerate a stock Zilla, but will run top end with one, considering you have a 14 tooth front, few months later the Zilla was equiped with a CT pipe, K@N filter, Boyseen reeds and 1 tooth larger front, and, well, Im not going to even go into that one, you educated riders out there make your own decision.
hope that helped guys


oh yeah, I dont wanna hear no B.S about how quads are not intended to be run on paved roads

 

****- do you know what the 1/8 mile times were? My slightly modded raptor's best 1/8 was 9.02. Just looking to compare and see. Thanks for the info. I am headed back to the track in a few weeks to see what the Trinity 686 can do. Thanks

 

1/8 th mile times were 8.89 at 71.2 mph, kinda fell on its face after that

No2StrokeB's that was a good post, very interesting. I have never even seen a zilla with a stock pipe in my life tho, prolly with a pipe it would murder the raptor. My 90 has never been beat by a raptor, I wish i could get mine to a drag strip and dyno. I wonder if I could run 12's, i kno i could get 13's.

 

Fast- you quad looks to have all the goodies. Any dyno runs? Run against any 686,720's etc? Thanks

 

I have seen a 89 Zilla with LRD pipe, 41.5 carb, Boyseen reeds, cool head with extensive cylinder porting, and 1 tooth larger front run a 13.39 at 88 mph, with a 8.02 1/8th mile time with a mph of 77. The Zilla was lightened quite a bit, something around 350 wet, but with a 195lb rider, so it was ******** a$$ nontheless. SO with your mods,lighten the Zilla up a bit and pray for a hell of a tailwind the 12s may be possiable

Yes I have a few 600 ft grass drag trophies from mine. It runs perfect, the only quad i've ever been beat by is another quadzilla. I am 250 which doesn;t help anyhting except traction. I actually drag with -2 swingarm, figure that out! Everybody else stretches theirs out and mine is shorter, it works good fer me because i guess my fat a$$ holds that front down, it will easily come up in fifth without a tug if i want it to. You wanna know whats really wild is I put my 14/28 gears on and go for a highway ride, that thing sails faster than any quad should, it is scary and it used to fold the maier plastics up to the handle bars!!
