Side Mounted Turbo Design
Turbo Mini Forums

i dont really know how these cad things work does it show you tube lenghs and angles. as i think i could potentially get one made or make one myself with help from a friend as he is pretty good with a welder and making stuff like this.

if complete would u be able to share the file?

yeah sure id share the file, once ive got the model correct ill do some drafts of the individual parts (angles and length), which ill be happy to share.

hi chris , id run no4 into the top of the pipe from no1 at an acute angle so it joins as near parallel to no1 as possible , ,middle 3&2 pipe parallel to no 1 pipe .so all the tubes run to the turbo with no pipes curving backwards towards the water pump end .
alternatively , if you have one , id use the mtro turbo manifold and sweep a single pipe from that to the turbo like the hybrid is .

like this (but prettier)


the heat retained by the big cast mani would help response .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Robert, is it wise to have the coil pack mounted almost on top of the Turbo?

sorry rob ,my brain fused at trying to associate the two words ''robert'' and ''wise''

Cheers Rob, so do you mean blend cyl4 and cyl2&3 straight into cyl1 , unequal lengths?

1972 998 TURBO SLEEPER

have 2 pipes going to the turbo flange , 1 from centre port ,and 1 from end ports .just dont turn no 4 towards the nearside , sweep it to the offside and blend into the pipe from no1 . so yes unequal lengths .

this is good stuff, nice cad work!


have you thought about vnt turbos? im looking at getting one, trying to find one about the same size as the t3.

on another note, what type of clutch are you thinking of using? the verto slave sits on the wok, may give you more room for the down pipe. from what i can see, Paul s's turbo sits high giving room for both.

what about a "sidemount" variation of the log mirage manifold, like 1 90 degree bend(for the furthest away port, 2 t pieces (for the other ports) and a bit of pipe to the turbo flange. FUGLY but bet it wouldnt crack lol

cheers wintersurfer, i am going to be running a verto clutch. i havent looked it to vnt turbos, just going to run a T3


Evo i was thinking about a mirage spin off, but i thought the software im using is pretty simple to use so i might as well go the whole hog and model something a little fancy, but as soon as i finish this one ill draw up your suggestion.

ive got my mirage off at the mo if anyone needs to borrow it.....

what diameter tube and wall thickness are the mirage manifold?
Cheers

i am taking note of everyone's input, i just want to get this model finished and then start of other iteration.



As you can see ive merged cyl1&4and used a seperate tube for cyl2&3.
merging the tubes takes ages as they are all on different plane and small changed were needed here and there.

the final model will be exact, notches and bends as they would be when fabricating. at the moment a couple of the tube merge and it look a bit messy

Looks good!

now cut no 4 after the 1st bend ,swing it round and into the no 1 pipe ?

so merge cyl4 straight into tube 1 without the 180Deg bend? Rob why shouldn't cyl4 pipe go back on its self?

its a waste of pipe and available heat to fire up the turbo sooner .

but what about the primary lengths should they be similar?

1972 998 TURBO SLEEPER

I'm not sure that I agree with Robert.

You need to balance the benefits of equally spaced pulses with the heat loss.

I would try to keep the primaries the same length and keep the heat in by lagging if need be.

You may have a space issue though.

i plan to wrap the manifold once finished. space has been on my mind, i vaguely remember the manifold mounting face to bulkhead being roughly 125mm, the model measures 115mm Max
