Building a drag motor for 1500 or less

[JohnZ]

If a guy was to say dump maybe 1500 into a banshee motor for duning, which way would you go?, can a guy reach high 50's in hp? How would you go about building your motor?

[iceman]

do a port and some pipes. youd probably make 50 if you went with a drag port and some inframes.

[rocketboy]

shearers 450$

vforce 200$

dune port 375$

k&N with outerware 50$

cut head 100$

33pwk carbs 325$

-------------------

$1,500

around 60 -70 rwhp depending on who ported it !

another few hundred dollars for a full drag port 350 motor

[switchblade]

Do you have a complete motor to start with?

[AK Rider]

How far do you suggest to mill the head? .030?

You should be able to make around 50 without the drag port or inframes. Toomey shows a dyno run with their T6's making over 50 HP. Of course they don't point out whether that is at the crank or at the rear wheels. But still add some timing, ditch the airbox and jet it right and you should be at or above 50 before you port. (I know we're not talking pipes, but pick something other than T6's if you plan to port).

you can get to high 40's/ 50 with pipes alone...and with little bolt ons/mods 50+. 1500 should be more than enough for building a duner. the way "I" would go is with davemooreracing.com ... a member here has dealt with him I think mp350

before I went with a stroker motor.........I had T5's, port, milled head, 2 k + n cans and bigger carbs..........and it squeezed almost 58 HP............IT RIPPED

Buy a set of cubs $875

Drag Pipes off Ebay $400

Set of 35mm or bigger carbs $300

--------

Total $1575

 

 

 

Not gonna win too many drags with 60hp. Better shoot for 90hp.

This sound like the right idea, but your stock clutch setup will not hold the power of a cub. You will need a lockup or 8 plate setup. You will also need a longer swingarm, some paddles that will handle that kind of power and if your really serious an override.

I've been running a FAST Racing clutch with no lockup, still holding. Don't know how long it will last but its put in 50 or 60 runs so far. You're right on the swinger and tires tho....I'm running a +6 with 10 paddle Haulers.

for 1,500 i can put you in the 75 hp range.easily, reliably.

[blueshee03]

you could shoot "passionre" a pm and talk to him.Jim's a great guy to talk to and he would be more than happy to help with any advice you need .he also builds some great running motors and probally has the best prices you'll find on porting,cubs or what ever you need.

You can easily get into the 60-65 hp range for around $750.00 if you have decent pipes already, port and polish, bore job, piston sets, Noss head. Not really a full tilt drag motor, but you were asking about high 50's so it might interest you..Jim
