Ok, the go kart project has decided that it wants to be turbo.

The kart is carbureted right now, but I've ordered megasquirt so it will be fuel injected here soon.

Engine is a 500cc kawasaki EX500.

I've been looking at the IHI RHB3/RHB5 but I can't seem to find any compressor maps for these bad boys. I was also pointed towards a Garrett T12 but I can't find those maps either. I'd also like to know the boost level of the internal wastegates these turbos have off their respective OEM vehicles (Chevy Sprint, VW TDI I think respectively).

Any suggestions as to a turbo to use? The engine has a 10.8:1 CR so I'll probably have to keep boost at a reasonably low level. (8-10psi with race fuel).

Last I heard the VW TDIs run 17psi...but I will try to verify that at work tommorow.

 

I've never fooled with internal wastegates... but I would assume there is no good way to lower their boost level?

here is a site that has a few GT compressor maps.

Cool, the GT12 looks about right.. but they are $$$ new...

 

I wonder if something like this:

Would even make boost... hehe. Good deal though.

 

what are you planning, something crazy like 100whp pushing 300lbs or something

 

since your on the topic.....Does anyone have an airflow calculator. I have searched for a bit an I can't find it.

 

what about those k03's in the GTIs? those are small, and u could probably find one of those cheaps due to many VW owners upgrading them....

 

this might help

you sure that is what comes on the TDI's is a GT12 cause i don't think it is

a ko3 from a AWD engine code would probably work very well in 4 th gear with a slightly larger version of this turbo i can hit 10 psi by 2500 rpm's

and you could get one for like 100 bucks and they are very durable just make sure to get 2000 or up

I got the perfect turbo you got pm

 

I was just reading up on Vesis (VW dealer tech program).

The 99+ TDIs use variable vane turbochargers, and don't have wastgates.

I'm not sure about the pre 99 TDIs.

 

Ok, it may be the European TDIs have the variable vane turbos, and we got turbos with normal WGs.

Manual and Vesis says the turbo runs 1700 to 2200 Mbar...you can convert that...I get something like 2.2 bar, which seems an awful lot.

 

gt12=standard internal wg config

gt15=variable vane

 

well heres the turbo for you project

IHI Turbo RHB5
Turbo Spec VA57A 9503
Serial No. RHB5 17 258A
Parts no. 35242058f

 

Cool, I'm trying to find compressor maps for that turbo ... to no avail...
