twin disscussion

[Rotore]

Blow off valve u kno wit a turbo set up

 

[BriggsTwins]

oh i thought so, but wasnt sure

 

[Rotore]

Lol ok

 

[BriggsTwins]

i am considering a turbo on the twin.... i moves enough pressure to make decent boost. but i look at it and realize im going to keep the RPM low and use the low end.....

 

[Rotore]

You can get up to 5000rpm on your twin dude thats a decent amount of exhaust gases to move a rather small turbo liKe a kp31 maybe a 14b or t25 if you add an emissions pump of a v8 to the exhaust manifold to increase exhaust pressure.

but i dont wanna push her that hard, im leaving the GOV on!!!!! ill take her to 4k at the most

 

[freakboy]

with the gov on you wont get 4000 rpm

Ok? Then youll either need a small as$ turbo or a big as$ smog pump buddy

 

[BriggsTwins]

i can, just needs tweaked.

 

[Rotore]

You can adjust it by moving the govener arm right?

 

[BriggsTwins]

actually by tightening a spring on it, it is actually built to run at what ever speed. the screw can give the governer more spring tension and thus more RPM

 

[Rotore]

So i could set my govener for 6000rpm by using a tighter spring?

Btw the turbo that would fit our engines are kp31 smart car, gt15 saab 9 or mazda 323

I did that with my subaru and it worked. It wasnt a twin though......wish it was.

yes tighter springs fight the governer's pull and keep it low, on the throttle, a spring change will change that

Somehow I don't think a mazda 323 turbo would work. Thats a 1.6L or 1.8L engine (can't remember which) making over 80hp without turbo, and reving to 6,000+. A ~20hp ~750cc twin isn't going to cut it.

Gt15 is exactly used on 30hp rhinos and 600's too dude if it does cut it say hello to a v8 emissions pump

besides 6000rpm is just the start im hoping to be turning over 8500rpm by next summer

 

[modelengineer]

Ooooh, well I've got 11000 rpm, so I win.

 

[Rotore]

Lol ill give you that lol hopefully ill be over 50hp by next summer

 

[freakboy]

i got 20,000 rpm but it aint a twin =( nor a turbo... nor a electric engine lol.

 

[Rotore]

Then what is it?
