i was talkin to a 30 yr rotary expert and i was telling him that i was putting a 48 MM Dell on my 13B and he was telling me that it wont do much for for my 84 SE and that i wont get any gains out of it and that a 52 mm is that only way i would get gains from how true is this? i was told a few different things by this person like a S5 intake will not bolt up to and SE and the an S4 intake would nothing for any HP gains how true os any of this? im not going to name any names here

 

Everyone Has There Own Different Coments Even If They Are Wrong They Swear They Know It All. Look Around For Some More Opinions. I Never Take 1 Look Around 1st

 

yeah im going to wait for somemore ppl to respond to this. he just doesnt make sense bc there is a soldier on here that is using a S5 turbo intake on his turbo SE engine, and this guys tells me it doesnt fit bc he has tried it, and everything else that i have learned on this forum he pretty much pulls out a B.S. flag on me. he also tells me that runnin it hard and at higher rpms it doesnt clean out the carbon and the ONLY way to clean it is to pull the engine apart.

 

first of all, find a new "expert".

secondly, if tuned right, you can get significant gains from a Dell - provided you have an exhaust system, too.

as for the differences between the S3, S4 and S5 6-port intakes, i'm very tempted to say it won't mean much since you're only the lower half with the Dell anyway. i think whatever gains you'd get from one year over another is limited to your keeping the fuel injection in place.

 

You Need To Stop Talking To That 30 Year Expert. He Probably Wants To Convince You Not To So You Can Give Or Sell Him That Carb Set Up. It Happen To Me Once. But Now I Know Too Much Jejejejeje

 

when i was talkin to him i was askin to get a S5 complete intake from him if i decieded to hold off on the carb setup for a while. i was by no means thinking about about using a S4 or 5 LIM and the sidedraft UIM. im alil slow some time when you say " i think whatever gains you'd get from one year over another is limited to your keeping the fuel injection in place" what do you mean by that sorry i am alil slow at catching on sometimes and it has to be broke down alil!?

i was on the TWM website and i was reading an artical about carb vs. throttle body and the Dell on a 6port was put down 211.4

 

You just have to rejet the Dellorto for a 13B and have a tuned exhaust and you'll see plenty of gains. The carb by itself on an otherwise stock 13b or 12a setup won't net you that much because you need the free flowing exhaust to really see the gains.

See www.gruntled.com for info on jetting for a 13B.

 

i searched cumberland rotary here on the forums and keep hearing the same thing so im turnin my back and never lookin back!!!!

 

think more along the lines of roughly 180 HP (if everything else is perfect) for a stockported 6-port with a Dell. For someone to quote 211, i'm fairly sure something else is going on (streetport or something).

all i'm saying is that unless you plan to run the stock fuel injection system from any one of the generations of 6-port engines, the year manifold won't matter much with a Dell. as far as i know, most of the changes made over the years were in the upper part of the manifold systems. you'd only be using the lower part with a Dell'Orto.

 

oh ok i got you now thank you! now i ve seen and heard from other guys on here that they changed the whole manifold and got gains that is true thought correct? i got a question about the chokes on the dell mine are i beleive 36 or something like that does the size of the choke matter and if i need a bigger size is it posaable to take them to a machine shop and have them mill them out?

 

well ... they have to either be 36 or not 36. you probably don't want to guess or approximate when it comes to tuning a carbie.

what i'll try to do is go back and find the specs on my old Dell system and see if i can post them for you as a base-point.

EDIT:

actually, you can get that info on www.gruntled.com

also, i put a compilation thread together a while back so that you can access relevant Dell'Orto information on this board. just do a search using Dell and my username.

 

cool will do! many thnaks !!!
