Guest WICKED ATV Posted September 18, 2006 Report Share Posted September 18, 2006 what do you guys suggest to be the best carbs for a 4mill rdz drag ported cheetah 100% 110 race fuel asphalt dragster. I see alot of guys running 39pwk's but on alky. could i use 38pwk's? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted September 18, 2006 Report Share Posted September 18, 2006 we have had good luck with 33 and 35mm pwk, but i know that a lot of guys are using 38 and 39mm pwk. i dont think you can really go wrong with any of them.

dajogejr Posted September 18, 2006 Report Share Posted September 18, 2006 badassbanshee479 had (has) a drag ported 4 mil cub that was running on gas last year, on 39PWKs...and it was very impressive. Of course this year he switched to alky, etc....but, his drag ported cub on 39's was impressive... I agree...any will be a good choice. I love my 35's. But, I think if alky is in your future, 39's would be the way to go!!! Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 20, 2006 Report Share Posted September 20, 2006 Hey...Wicked. I'm not sure if you got carbs yet, but a guy in the for sale section is selling a pair of 35PWKs AND K&N Filters for 200 bucks. That's a steal....pick 'em up if you can!!

Guest WICKED ATV Posted September 21, 2006 Report Share Posted September 21, 2006 thanks for the heads up on the carbs for sale but im going to take your first piece of advice and go with 38 or 39 pwks. im wanting to run my cub off straight 110 octane but alcohol may come into the picture. you never know. thanks Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 21, 2006 Report Share Posted September 21, 2006 I know what you mean....headed down the same path myself.... Already on 110, and alky is coming very, very soon... I would love to see how much more HP you would get out of 39's vs. 35s.... I got a steal on my 35s...and I'm happy. But, I might end up selling my 35s for 39s...not sure yet.

odaen Posted September 21, 2006 Report Share Posted September 21, 2006 I picked up 3HP going from 36's to 39's on race gas. TQ numbers were pretty similar though between the 2. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 21, 2006 Report Share Posted September 21, 2006 Question, Od.... (and thanks for that input)... Could you tell, seat of pants or by racing the difference? I'm wondering what the difference would be on alky....since we all know how much alky you gotta flow!! Quote Link to comment Share on other sites More sharing options...
odaen Posted September 21, 2006 Report Share Posted September 21, 2006 To be completely honest, I ran my 36's for a bit, then dyno tuned my bike, and with the addition of the carbs and some other stuff, I think I gained about 9HP. Yes, I could definitely tell the difference there. But a 3HP gain when you are talking about 100HP would probably only be noticeable if you had 300ft times to compare.

dajogejr Posted September 21, 2006 Report Share Posted September 21, 2006 Thanks for the reply.... I put on RDZ inframes, 35PWKs, Nology and a Dyna all at the same time...so, I made a big jump from stock carbs, igition and T5 pipes to compliment my cub....
