Hi, i have a hyper 7...8-Port and i can't seem to tune it correctaly, my mate's hyper 4-poprt is whooping my ass...please guys help me! (btw i need help tuning not advice on hop ups...cheers!)

I was going to say OS 20E carb but never mind.

the problem is the carb, and that the 4 port is a superior motor anyway. SMan was right , get another carb, any Rossi carb will do the trick too.. Failing that. tell me what pipe, fuel and plug you are using also ambient temps.. and ill tell you what to do..

hey, thanks for the replys, i am running the stock black "thing" that comes with it, i am using 20% big bang modeltechnics and i don't know the ambient temperature. i hope you cna give me some advice from this info i have given you

i have a 20e carb for sale if you want it, i will give you a really good deal on it.

Hey dude, yeah how much, i live in the UK so would you be willing to ship?

hi, can i just ask or makesure, the 8-port engine, the only physical diffrence is the fact it has 4more exhause ports, this make the engine faster because it allows the exhause gasses to be expelled faster than on a standard engine. this is in the same way like a 16v engine on a 1:1 scale car or a 20v engine?! the exhause fumes go faster there by making the time taken for the piston to move back up alot faster, thereby making the momentum of the engine generaly faster.

well in my experience I find the 8 port faster but the 4 port is a hell of a lot easier to tune and keep it and more reliable

btw benny2k to you go 2 consett

The exhaust port is no different between the 8p and the 4p
the 8 port engine just has more intake ports,

had enough is right. 8 port is really a 4 port but with 4 extra lube ports. 2 smaller boost ports at the front with extra lube ports and same on the sides..

here are some pics of a stock 4 port then a mod 4 port, i don thave an 8 port pic on hand...

hey browney, erm consett, nope is there a track there likie, the only problem with most of the tracks around the north east is they all operate on a weekend, and i work both saturday and sunday, i wish there was a place that did a session on a weeknight, that would be cool!...my e-mail is [email protected] (i made it about 10 years ago...lol..don't laugh) add me to msn if ya have it and well talk more mate! thank you everyone for posting about the engine i am still havin a little trouble undertanding it but i am sure in time i will figure it out!...lol...talk later guys!
