lt1bird Posted December 17, 2010 Report Share Posted December 17, 2010 (edited) I am about to build a big banshee engine. Ive got a bunch of 535 engines but need a whole lot more. What is the best engine for drag racing? Im looking to stick to 2 cyl... whats the largest going 2 cyl right now and about how much hp are they making? Whats the hot ticket....It will be getting nitrous as well... Thanks for any info or opinions you have to offer.

sheefreak Posted December 18, 2010 Report Share Posted December 18, 2010 There is much larger than the DMX. Scimitar and Caracel. I have heard up to a 105mm bore. You would prolly be looking in the 200ish HP range. Quote Link to comment Share on other sites More sharing options...

The 1st consideration you should worry about is getting the motor to stay alive that long. I recommend staying with one of your 535 engines to learn the set-up.

kdaddy Posted December 18, 2010 Report Share Posted December 18, 2010 well the will all last if there built right and im sure all you would have to do is build urf 535 and do a turbo set up with nx...im sure it will be plenty fast enough Quote Link to comment Share on other sites More sharing options...
lt1bird Posted December 18, 2010 Author Report Share Posted December 18, 2010 I was thinking of doing a turbo with the 535 but I really dont like the idea of the added weight, complexity etc. So the big engines do not last long? Quote Link to comment Share on other sites More sharing options...

You will have pros & cons with any motor size. A few quick concerns about these larger motors is the piston weight & depending on the stoke, the piston speed.

lt1bird Posted December 18, 2010 Author Report Share Posted December 18, 2010 What about a big shot of nitrous. Whats the concensus on max nitrous shot for a 535? I have forged crank and matoon cases. Quote Link to comment Share on other sites More sharing options...
Blewbyu Posted December 18, 2010 Report Share Posted December 18, 2010 The thing with additives, such as turbo's, nitrous is there not always going to be consistant. Are you looking to set records, or be consistant? bracket racing, or heads up? Look on cpindustries.com there is a list of all the cylinder setups your heart desires. Sky's the limit, or I should say $$$$$. lol Quote Link to comment Share on other sites More sharing options...
lt1bird Posted December 18, 2010 Author Report Share Posted December 18, 2010 Im really looking to make a very fun, fast bike. Its not a quad, its a street bike. I have a few of them. I want a high 8 second street bike via 2 cyl 2 stroke. Bike should weigh in at about 275lb. Im thinking I will need 150 plus hp to do it.

kdaddy Posted December 19, 2010 Report Share Posted December 19, 2010 usually a really big shot of nitrous will freeze tha reeds in tha 1/4 mile....turbo is tha way to go... tha whole set up adds 20 lbs maybe and ya could make 200+ hp with about 18lbs of boost.....

lt1bird Posted December 19, 2010 Author Report Share Posted December 19, 2010 On a drag bike the room might be tough....for intercooler etc... Guess I could mount it in front and mount the radiator out back. Guess Ill have to do more reaserch on the turbo stuff. Ill check out cp as well...

I thought I found info somewhere else that the motor is a 535. I think they mention it as a 500 in the coments section. Quote Link to comment Share on other sites More sharing options...
