Anybody ever seen this turbo setup before?

That looks suspiciously like a Weber side-draft carb.

Maybe I'm wrong, but at first glance, it doen't look like anything on my car.

 

If anyone can confirm if it can be modified for a Qv engine I will definitely be tempted

 

OK, it looks like this kit replaces the carbs with the airboxes. The other carb then feeds both boxes? If this is how it works, that would be strange?

 

You'd be mostly starting over. You could use the OEM plenum instead of the air boxes that won't fit, but the exahaust manifold will take some work...you'd need to weld on a new flange or make an adapter plate I think.

 

These types of set-up tend not to work very well. The carb ends up basically as an up-draft set-up so the fuel settles out until it's all warmed up, making it hard starting and not very drivable until it's completely up to temp. Once it's warm though, it should be fine.

 

Looks like an example of Koenigs first Turbo setup for 2 valve 308's, we had one in a few months ago....never again absolute bugger to start and drive at anything other than full throttle

Pete if you really want more power play with Motec and a supercharger

 

That system is a draw through system. There are only certain turbochargers that can be used for that kind of system. This is becourse there needs to be a special seal in the turbo becourse both fuel and air is drawn through the carb and into the turbo were its pumped into the engine. An intercooler can not beused on this type of system becourse if there is ever a back fire the whole thing will blow up like a bomb. The only way of intercooling these set ups were to use methonal and warter injection. These systems were popular during the early 80s. And companys like Jan speed and Koning pioneered the systems for the road car.
The Picture bellow is a 5 ltr rover V8 engine that i built for a TR8 during the 90s, based on the Janspeed system. It also was a twin turbo draw through unit,drawing through two SU carbs and entering two TO4B turbo units, and also had methonal injected along with a shot of nitrous The engine was running at 17psi and was giving 400+ bhp at the wheels with out nos. The whole block was rebuilt with forged pistons and group A rods ect, ect.An EMS ignition retard untit was also used and a Mallary Dizzy was also used.
This engine was built by my self and eventually went to fuel injection. The car was also featured in a few UK custum car magazines. There was no problems with "puddling" problems with fuel on this particular system, but some others in the 80s did becourse they used webber carbs.A dam good good engine

Chas why mess around with TR8 when we all know you want one of these (although god know's how you'd fit )

I do indeed And i would remove my legs

 

Darn, chaa...you ARE pretty handy!

Hat's off....(cowboy hat, of course)....LOL!

Looks like you kept stuffing things under the hood, 'till it was FULL!

 

Cheers Andrew, I was just keeping my options open for future mods to the car ;-)

 

Pete

When you've got a few minutes (hours maybe ) give me a call........would love to help out with your project

 

Sorry Chas meant the Mondial QV not the Dino ....plenty of leg room (you'll fit in the Dino if I do )

 

Isn't it a bit odd that this turbo system is a single turbo, mounted to only one of the headers. I also wonder if that header (it must be the rear bank header) mounts with the turbo's flange up? Otherwise, the turbo would be very low and the carb would be very low, like oil pan level. I have a turbo book right here written by Corky Bell (a turbo "expert") and he says "Weighing the merits (speaking of draw through versus blow through turbo systems), there is virtually no reason to build a draw through system unless one lives in a year round hot climate and never intends to produce serious power". Further when suming up the benefits of a blow through versus a draw through system, he says "The draw through system is a dead fish". The only reason I can see to buy that system, would be for fun just to see how it worked during the hot summers. If the bidding goes over $500, it's a waste of money.

 

i might be relatively new to this forum but not to turbos. Maybe you could clarify why is that kit is so cheap? I would think the turbo is shot and in dire need of a rebuild.... who knows what else. I don't know much but for a custom set-up, the fairly recently introduced Garrett GT2871R turbo would be great (small w/a larger powerband, can hold up to 440hp with very quick spool up time.)

 

You must remember that the Corky Bell book was writen in the mid 90s when there was a better understanding of road turbos systems. So thats why he said there was no reason to build one of these systems (in this day and age). I also have that book as well as books writen on the subject from the late 70s were they raved about this kind of system.
It was also not unusual to build a system with one turbo. But now that you mention it and looking at the picture there is a manifold missing!!!! How a single turbo system works is it is connected from one manifold to the other manifold via a steel link/ballance pipe. So there for working from the exhaust from both manifolds. So in a nut shell the system wont work with whats in the picture. And as some of you will know the key to any turbo install is the manifolds. So now you all know how a single turbo system works........please....thank me later

 

Cheep becourse there is a manifold and link pipe missing. Also if you look at the top of the pictured manifols you will see the take of flange for the link pipe to the other manifold. Also there is the old type BPM waist gate on it. If this has a hole in it.....then ya f**ed becourse they dont make them any more.
Also that turbo that you mention could not work on a system like this becourse it has no fuel seal in it The one you mention is designed for a "blow through" set up.

 

Thanks Andrew, My finances are bad at the mo due to other projects etc..., I was interested in this turbo setup if it would fit and sold fairly cheap, I will defo ring you, I still need to know how much fibreglass/resin/bonding i need to order, Regards Pete

 

LOL!! not with out the second manifold ya wont

 

waxing poetic.........beacuase TR8s are Great!

 

Yep, I realise that now, I would be better starting from scratch

 

My experience with boosting 308s is that they are ari pigs and dump about 1/3 of what goes in right back out the exhaust. So to get 440hp, a gt30 or 35 is probably in order.

I'm playing with heads and cam timing on my QV now trying to get the air pig thing solved, but as is I'm flowing about 80 lb/min to make 500hp. The set-up I had befroe this one flowed about 55 lb/min to make 360 hp (non intercooled)

 

With all these extra Hp mods, how will the crank fair up, can it be left standard or will it need to be uprated, or is there a risk of big end bearings/shells going
