Just mocking up the new plenum and intake and just about got the supercharger to fit. Inner wing needed a brief appointment with Mr. Lumphammer, but got about 1/2" clearance on s/c body now.

Worked out how to fit everything apart from the intake pipe. The mismatch between the s/c outlet and the intake elbow is severe. Tried all my bends in metal and silicone but nothing anywhere near close.

The diameter reduces from the intake to the s/c also.

I was wondering if anyone had any ideas on anywhere to search on the net or anywhere for some really tight bends. Could be cast or plastic. Or any cars which have a really tight elbow fitted somewhere as standard. Ta.

 

 

 

 

i know this probably sounds stupid but cant you loop around the back of the charger.

:shock: fook me when do ya wanna do mine, only jokin mate lookin good.

here is one specialist http://www.velocityair.cc/elbows.htm

Can't see a way round the back. That tube place looks good for the future but for this bit I don't think any bent tube is going to be any good. The problem is that the bends have to be so tight that the inside radius of the bend will be zero. Nothing will bend a tube that tight so it's either a cast ally elbow off something, or the only other thought I had was to make a wooden former and get a silicone hose maker to mould a hose round it.

 

would rather not go down the hose route tho', tried that before and it looked w@nk.

Best compromise would be an ally bend welded onto either bit, then a reducer, and then a 90° silicone elbow. So just one ally cast tight elbow could be all I need.

cant you turn the plenum intake facing the other way and you could then use a normal 180 and come back across

Thought of that but there's no way to get a pipe across from the s/c to that side, unless it went right round the back of the plenum.

Can't you use an "S" shaped pipe ? or maybe a G shaped pipe direct from plenum....or even have the plenum pipe more angled towards S/C and use J shape... nice bit of engineering there so i guess you prob already extinguised most possibilities

 

 

Doh !!! just read your other post.......... :slap:

the only other way is to make an ally box from the s/c to the t/b with a matching face consisting of a stub the same size as the facing item and then sleeve them on with say 30mm pieces of silacone tube

Just an idea, but look at cast alu plenum's from cars with SU carbs (classic Mini's etc) - some of that stuff has pretty tight angles, but maybe not big enough diameter.

yea and as above i think this would be a near hit,the pipes off a v8 rover with the su carbs and you get 2 of em ;)

thats some amount of work mate fair play, do ya not know anyone to do a custom pipe to fit???

http://viper-performance.co.uk/index.php

 

This place any use to you Keith?

 

I had some hose from them before and its good stuff, they might be able to do custom stuff, also says they do ally tubing as well.

 

I'll have to pop round again sometime and see your v8 again!

 

Mines not too far off now either!

Thanks everyone so far. That rover v8 pipe looks handy. My mate's into rovers so I'll pop round tomorrow. That viperperformance place looks good too, cheers.

just out of interest what size lump is in that lovely beast and what's it gonna push out with that charger on it? :hyper:

would guess its a 5.7 litre chevy block pushing about 350 as standard with a supercharger add another 100 or so but the tourque will be very good and hence effortless acceleration in any gear ........but thats a guess going on when i ran 60's and 70's striaght line .Americana

on the plenum front where the large oval flexi conection for the air intake pipe is ..can this not be removed and an alloy box made with 4 mounting bolts to connect to the 4 bolting the throttle body to the plenum with a tube inlet on the same side as the throttle body cam and go directly from there onto the supercharger , does the flexi hose need to be there ...as the plenum and supercharger are solid fixed and shouldnt flex if a expansion joint is needed then it will be easy enough to put one in on the run to the charger ?

Having seen the photos of you machining the plenum could you not make something that would suit. I am not sure how you would go about it but if you can make the plenum you must be able to make a 90 degree bend that will fit. It would probably look a lot a better as well.

 

I also found this company online.

Must be frustrating to get all that work done only to be held up by a pipe.

 

Good luck with it.

can the supercharger be clocked like a turbo? then you get it point upwards and use 2 90 degree bends to sort it

If you alter the outlet of the sc to have a 45deg coming out directly from behind the main sc body should give you enough room to get another 45 onto the plenum you would have to get the 45 welded directly onto the sc outlet

 

Side entry plenum would be best have a look at the design of the single turbo vg plenum's, I think the cima set up is what would look best with the TB facing in the direction of the sc outlet, not ideal from a flow point of view

 

Do you not want to run a fmic and take the outlets to either side of the car ?

That engine looks SWWEEEEEEEEEEEEEET......

I think you should be asking santa to get you a petrol station for xmas :)

Thanks again. Some interesting ideas in that lot. Just a few answers in order....engine is 6.3 litres, looking for 500hp and 500torque to start with. Hopefully this will be enough to keep me happy once and for all.

If not I'll probably set it up for say 600+ but would only really be happy with that if I was to put forged internals in, which won't be cheap, so hopefully 500 will do.

 

Pipe issue not exactly holding me up at the mo, just trying to sort things out at the top end and then the engine has got to come out for balancing. Put some different pistons in after Iblew it last time. They are only 7grams heavier so thought they'd be ok but there is a bit of a vibration at 4000+ so going to have a look.

Have made the balancing rig, just waiting for the drive motor to arrive.

 

Ally box method in place of oval bend could work. might try a couple of sketches first. Got to look right tho.

The s/c can be clocked to point upright but will not do it in the 300 engine bay. Nowhere near enough side room. It gets a lot wider as you spin it.

 

45° pipe welded onto the s/c outlet is veeery interesting. Going to measure that one up shortly.

 

Dont want to use an intercooler. Have gone with water/methanol injection instead.

This Emerald K3 ecu looks brilliant. It can store 3 maps which you can switch between while driving. My plan is to have a mild map for normal driving and then a more aggressive map (timing advance mainly) for max hp. The water injection should stop the engine blowing up with more advance but relies on the water keeping flowing.

So I've got a flow meter to measure the water being injected. When the flow is above a set value then the flowmeter can switch the ecu to the other map. if the jets block, or water runs out it will revert to the safe map.

That's the theory anyway. will know in about 3 months...

45deg should work looking at the pic you will need the outlet of the sc cut back so the 45 is as close to the body as possible, cool engine swap keep us updated

looks like it wont fit under the hood, would be cool for the top of the engine to be sticking out of the hood like a muscle car.
