i have a 1999 banshee with: mild port,polish,cut head,hot rod crank,v force,+4 timing,boost bottle,lightened flywheel and .020 over bore. i want to make it faster with out spending to much. i was thinking about making it a 4mill stroker or bigger carbs. i am also running pt mid's. any good suggestions? :headbang:

enhance your portwork. itll be way cheaper than stroking cause you need virgin jugs to stroke it. just take it to the original porter and have him remove a little more. that should make a modest increase. dont have to go wild just maybe get some more topend. maybe some diff pipes also. like t-5s or cpi's. something that will respond to the porting a lil better.

what about carb's

don't worry about carbs until you get into a stroker or really agressive porting. dynos have shown that the stock carbs can outperform larger carbs overall and with your mild port, I'd wait.

 

If your looking for more top end for a drag or dune setup, then some 28's would be fine or have your stockers bored to 28. See, the larger carbs you get, the more the powerband moves up in rpms. If you were to stick a pair of 35's, then you'd have a lot more top, but your low and mid would have left the building.

 

If your looking for some more low end, switch to a single 35mm from Trinity, and actually, the single carb setup will give you a lot more low and mid as well as more top end than the stockers will give you. Also, the single carb will go hand in hand with the PT Mids.

 

If it were me, I'd either get the single, or stick with the stockers and get a TORS eliminator kit.

 

On a sidenote, you can get your crank rebuilt with long rods, cheaper than you can buy a long rod crank, then throw in some Wiseco 795 pistons and wallah..... one long rod banshee, although, depending on your present porting, you might have to have someone do some port timing adjustments.

depends on how far they were ported before.

he said midly, but youd really habe to look and see.

i l ike mt pt's they pull hard from mid all the way through. i dont think that is really a problem. But i was wondering why you need a set of non ported jug's for a 4 mill stroke?

because when you do a stroker you have to adjust the transfers to correct port timing for the longer stroke. im not a stroker expert so i dont know the exact reasoning, but thats what i was told when i asked about having my ported jugs turned stroker.

This is the case when you have a motor that doesn't pull enough fuel in. If you had a stroker, you'd gain bottom and top with 35mm. It's been done on the dyno. That why sredish said "don't worry about carbs until you get into a stroker or really agressive porting. dynos have shown that the stock carbs can outperform larger carbs overall and with your mild port, I'd wait."

 

I totally agree with the porting. You can get so much power out of a standard 350 crank with porting... it's insane. You... in theory... should be able to get even more out of a stroker, but it all depends on the builder.

 

The reason they are saying you may not be able to use those cylinders for the stroker is because some builders take a lot from the transfers and those can't be used on a stroker. So builders don't take much out though.

i am not really sure what size are stock banshee carbs. i thought 26's. so you saying to go to 28's. i have also had the tors kit removed from day one. maybe i should just go with a full race port.

I got a dune style port from passionRE, you can see all my mods in signature and i pulled 68hp on the dyno week befor last.

I didn't see what your air filter setup was but if water isn't an issue maybe try some K&N pod style filters for some more air flow. If you want bigger carbs motocarrera.com has 28mm flat slides for about $100 ea. Maybe a prodesign or boss intake manifold designed to go with your V-force reeds. I'd also say chances are good that you could still use your stock jugs for a stroker, maybe send them to a builder just to find out. But you said less expensive mods, strokers don't fall in the cheap category.

its not entirely true to need virgin jugs to port. in fact if they havent been touched much he san still use them for a 4 mm set up, thats how mine were. i would go ahead and enhance the porting. thats gonna be the best way to get more power the cheapest.
