Yfz 450 Dyno

[jim_beam_racer]

im lookin at gettin my motor rebuilt and i want it for fully flat track tt balls to the wall horse power so what would you guys recommend for an engine builder if maybe you could post your dyno sheets and all the mods you got that would be great

[Ryan Plaugher]

If your going for all out power i would contact curtis sparks. Im not sure what your limits are for displacement. I would go for a stroker engine because of the high torque they put out since your doing tt.

[jim_beam_racer]

i gotta stay at 450 but if i could go over id have a stroker big bore
who do you think i should go for with cams

[Ryan Plaugher]

i would go with what your engine builder recomends. I have hot cams and they pull realy well but you may want custom cams.

[jim_beam_racer]

i was thinkin web or ron woods but ya what ever they want

[honda4life72]

you can run open a,b,c if you want to do a stroker .

for tt u want a huge cam, like a web cam . tt is all mid to top rpms.

[jim_beam_racer]

i run in open and but i also like to run in 450b and ya i know i want a bigger one but i got bottom and mid power now cause im usually in firs when i come off the line but they get me with top end

yo man I would take it to dave gibson at East Coat ATV...I not sure where you live but...give him a shot..

[jim_beam_racer]

do you got your motor built by him

[jim_beam_racer]

i was thinkin rossier because then i could keep it at 450 cc but thanx anyways i can get discounts on my own

[WOLFPACK]

Rossier would be a good choice and they have a dyno in house to tune it.

Just so everyone knows MaxPower does much more than just super Big Bores. They are a good choice for any motor build.

talk to james at jms performance. hes in new carlisle indiana but its worth it. i have an internship there so tell him matt sent you. he has an in house dyno and anything else you can think of. he is sick with tuning motors. in 2001 he helped mike larocco with his championship. hes also helped chris gosseler, travis preston, and other big names. the # is (219)-654-8589 . hes got great prices.

joe at rossier builds fast reliable motor i know him personally he is a great guy that make very good hp numbers i know several people that run his motors and they rip. as for max power i know one of the engine builders there rich and they make some nasty motors. my buddy had them build a full yfz523 and it rips hard. i am not sure about 450cc motors but i am sure they can turn it loose. another very good builder is dasa they are top of the line too. you would be happy with any of them.
