I have a Lycoming TV0-435B1a helicopter engine (Bell 47) which is fitted with a Garrett AiResearch TK-0659 turbocharger. The heli engine is 435 cubic inch and the engines max rpm is 3,200rpm

I want to try and put it on a 258 cu in Jeep I-6

A couple of issues

1. I've been looking for a turbo map for the TK-0659 turbo and can't find one

2. This turbo is sized for a 435 cu in engine at 3,200rpm in it's normal application , I want to try and put it on a 258 cu in Jeep I-6 which means in this application it should be good for airflow up to 5,500rpm

Anyone tried using an aircraft turbo ?

Would it work ?

Would it be a turbo lag dog ?

Thanks

Tony

that is a HUGE turbine housing. if its a split design, you could block off one side to spool it faster.

Yes , it is big , is it because turbo aircraft engines are generally operated at constant boost ?

As I said though it was designed for a 435 cu in engine at 3,200rpm

Using a CFM calculator this comes in at 335cfm and a 258 cube at 5,500rpm would be pretty close.

It's a lot of work to fabricate manifolds etc if it's just not going to work so hence the post to see what the experts think.

Turbo lag is going to be an issue, but are you in a time dependant situation (racing) or cruising? If cruising who cars how long it takes to spin up so long as you are building power and not restricting the normally aspirated air flow.

The other side of the coin to turbo lag is over boost on throttle close, because of the mass of the turbo it is going to take as long to spool down as it does to turn up. You are going to sound like a truck with air brakes when you pull up to a traffic light.

Hey Big Dave, been a while since I've been on here

I have a Jeep J-20 pick up which I use for work and occassional off road use so I can live with a bit of lag

A bit of noise at the lights may be a bit of fun and to control the overboost I'm using an aircraft blow through carb so I can put some sort of over-boost relief valve in before the carb.

pull that turbo off, take a look at that housing and see if its divided. if not then you most likely wont be able to make it work.
