I talked to BlackMagic Performance today and they said with swaping out the jugs and head the kit comes complete with gaskets and all and gives you 160hp's!!! if you add Reeds and pipe loooooooookout he said... So I am taking apart my sled this weekend to send them my core and they will then send me the complete kit with the upgraded computer as well for the EFI..I will post results as I get them...



let us all pray for lots of snow....

It was 1500.00 , and you needed to send them your jugs and head first..If you wanted to keep your efi you need to buy an upgraded computer which was 250.00...

Check out blackmagic.com they do have alot of the answers you are looking for.. I do also think that 1500.00 for the kit is a bit high, I mean all it really is are a couple of pistons,new cyclinders,new head and some gaskets...right ? does any one know if you can just buy your ouw pistons anf have the jugs boredout yourself?

Yeah, If you haven't already purchased the F8 kit, I would go the other route. You probably wont be able to bore the cylinders up tp 800cc, But you could see what the biggest piston Wiseco makes for your sled, purchase the pistons and rings and have the cylinders bored to the piston size (don't let anyone bore without having the pistons first, they need to be measured for tolerance). You might be able to get up to approximately 750cc from your 700. I had the cylinder on my quad (single 250cc) bored .80 over, which is the max and it brought it up to about 270cc. Wiseco piston was $90.00 (a piece) and bore for one cylinder was $30.00, done by a friend who also trail ported while he had the cylinder. Regardless this is alot less than the F8 kit, which leaves you plenty of money for other mods that could probably bring you up to the same horsepower ratings. You could probably do this and still get the computer module for the EFI through blacmagics which probably just ups the amount of fuel/air and advances the timing. Just a thought. Hope this helps with your decisions.

but if you have the money to spend the f8 kit is definetely what you want, because after that you can then pipe/clutch/reeds/etc and have extreme gains, that woiuld only equal the f8 kit if you just added wisecos and had a bigger bore.

You would have to call Wiseco. ( 1-440-951-6600 ). They will tell you the available sizes for your sled. They generally make pistons up to the maximum bore of the cylinder. So whatever they say is the biggest piston will be the max you can bore before resleeving. They should be able to tell you what the displacement of your engine will be with the bore.

don't get a 711 motor they are junk. go with d&d or speedwerx. as for the f8 kit. my buddy i race with put one on his f6 nightfire and it's strong but still can't beat his f7 in a drag race. alot of money to spend for that kit. just clutch and gear your sled and it helps a ton. i heard the stock pipe is pretty good and you could add reeds if you want a little more out of the motor. or just wait. cat unveils the 2005 sleds to the dealers on feb. 10th. they could have something big in the firecat chassis.
