smallest turbo?
 

what is the smallest factory turbo out there?

and do you think it would spool at all on a 400cc 2 stroke motor??

has anyone here ever turboed a carb motor, and is there any problems turboing a 2 stroke?

Re:smallest turbo?
 

smallest turbo??? try a Daihatsu Charade turbo.
They look like a donut. I think it would be ok for the 400 cc it is in a 600cc engine so. uhmm carb hmmm that you need a special carb for turboing. do some research.
turboing a carbed is more diffiicult then turboing a fuel in jected car

Re:smallest turbo?
 

well, that depends on the carb. you can use a stock carb if if you it on the intake before the turbo, since carbs have to work on vacuum. if you force INTO a carb, instead of PULLING air through a carb, it's going to spit fuel everywhere and the carb is going to have about a 30 minute life span. but yes, you do need special carb if your going to be forceing air into a carb, instead of pulling it through. so if you want to turbo a carb, stick the intake of the turbo to the bottom of a carb, and an air cleaner on the top of a carb, and run the boost side of the turbo straight into the manifold. on the up side, doing it this way, you get GREAT air/fuel mix since the turbo is sitrring up the air/fuel in the turbo itself.

Blow thru apps aren't hard on the carb, depending on carb design.

Any Holley with brass or nitrophyl floats and mechanical secondaries are pretty much ready to go, you just boost referrence your float bowl and mechanical fuel pump (if applicable).

If the carb spits fuel everywhere, then the throttle shafts are worn or the carb isn't quite up to it. You can seal the shafts, or stick the carb in a pressurized enclosure.

Honestly, turbo carbs are easier for the DIYer than EFI, unless you have a chip burner and a pile of electronics ---- on your floor like I do.

Chevy sprint turbos are really small..

Re:smallest turbo?
 

I've heard the Sprint turbos described as "chihuahua head sized turbos."

That should run anything from a Briggs + Stratton to a medium sized motorcycle, IMO.

Re:smallest turbo?
 

I have not seen the sprint turbo yet. The smallest turbo I ever saw was from a dodge stealth rt. That thing was tiny. On the turbine inlet I bet a golf ball would not fit in. Probably litterally half the size of a t3.

Re:smallest turbo?
 

uhm dont they make tiny turbos for RC cars?

i saw a pic on the net and it was like the size of a loonie. :)

Re:smallest turbo?
 

yeah try the sprint turbo, but I think the chaade turbo is smaller, smaller than a Garret TBO15

Re:smallest turbo?
 

yeah the sprint is like a 1.1L engine. i want one of those turbos, so i can turbo a moped or something :P
