Mats, I am not saying a big single turbo is always the solution. Just that it seems to be the dominant set up for max power on dyno queen imports, and aircraft. You are right, about aircraft. They essentially run a constant rpm and lag just isn't an issue due to the operational nature of these engines.

Barry, your early work looks good. It looks like you thought out of the box to solve fuel issues.

I must say i was taken for a quick spin in a Twin turbo gtv6 last year, fun as it was, it never looked that quick, inside the feeling of boost was strong. But i knew it needed something more, and i know it wasnt running the same rwhp as barry's. Also engine bay was very cluttered, and the turbos very small, IHI's i think. Guy at Garrett said he wouldnt touch an IHI, cos i inquired about them.


He is custom building me a Garrett one instead......for my scooter. :roll:

Just where do i put the bloody thing.....!("Theres some aussie slang for ya!" :oops:

This engine was built in 1993/4 or there abouts..The programmable systems then were horrendously expensive and only available from the big names..
We had to make things work in those days and I must admit that Hugh McInnes`s book "Turbochargers" was a tremendous help in setting up the above car..and a few subsequent ones..
Most L Jet or AFM types had suck through setups..I remember looking at this and thinking that if I could blow through the AFM ,I would get a super rich mixture as soon as The turbo started boosting .This way the low boost would slam the flap wide open and Id get more fuel than if it sucked through.It worked.And the AFM could handle 1 bar boost as long as you did not have a lean mixture that caused a backfire and blew it to shit street!! :wink:
I had a few of those as well.. 8)
Big diameter ally bends were also not available,so it was cut and weld to get that intake bend to work.After every weld it was in with the cirk grinder to clean up the inside weld and then off to get the next one welded..It took a few days to do this as I never had a TIG welder at that stage.

Damn,those were exciting days..
Now I think I might just go farming.. :D

I ommited to add that a suck through AFM also produced significant lag in throttle response... :!:

Greg: I hear you, I just added some notes.

Barry: Blow through AFM? Damn, those things are flimsy as hell. I would have thought it would go lean when blown through though.
Laggy when sucked through? No shit, guess you have driven a 75 turbo? :roll:
