Supercharging/turbocharging

[cyman 1 1 Cars]

hi, how many 205 owners are interested in turbo / supercharging ?

Iv'e had alook at some of your threads regarding the subject.

there are lots of info and books you can get all the info you need.

as long as you are sensible about expected power gains it's fairly easy to do.

here's the link for some pics.

i will add more detailed pics soon.

Hey you sent me some pictures I was the guy on ebay asking about your engine when you were selling an mi exhaust manifold, welcome to the forum, got any new pics/vids?

Whats the spec?

Hello - are you selling something??

[cyman 1 1 Cars]

hi ben, nice to here from you again.

yep, there's some more pic's to come.

have you had alook at the pics on the link.

iv'e still got to finish the mapping, but it feels pretty powerful, and the turbo/supercharge combo works great.

air temps are lower than predicted.

Whats the spec mate?

[cyman 1 1 Cars]

hi, i'm not selling anything !!!.

i'm just telling you what i have done. and if you are fairly handy with a spanner and can do some basic drawings you can do what i have done.

the spec.

 

 

--------------------------------------------------------------------------------

 

 

1900 mi16 low compression engine machined and ceramic coated

std head and cams

new flywheel

twin plate paddle clutch

diesel gearbox std

sds injection system fully programmable 3bar map

550 cc injectors

chevy 70l throttle body

billet trumpets

complete new induction system

opcon screw supercharger

kkk turbo hybrid 360 deg cutback bla bla

s/s turbo manifolds

kkk remote wastgate 2 boost settings 17 & 21 psi

pace intercooler

electric water pump

full aeroquip hoses

2 fuel pumps

remote soliniod reverse linkage

that all the basic stuff, i could go on,

as you can see this is alot of stuff,

but if you were to go the easy way, you get a std mi16, lower the compression ( machine pistons ).

fabricate exhast manifold ( using origanal manifold ).

sort intercooler. you will need to sort extra fueling and maybe boost retard

depending on boost you may need more engine managment !!

very impressive

 

have you got any torque/power graphs?

[cyman 1 1 Cars]

hi, sorry, not had it on the rollers yet.

i'll keep you posted.

can i ask have you lengthened the font of the car at all? cos you look like you have plenty of room to fit the supercharger but i'm sure there wasn't that much space on mine. have you binned the alternator?

[max0 5]

wow

[welshpug 1,657]

love the engineeriong aspect, but it looks fugly to mee!

[cyman 1 1 Cars]

[hi, yes, the front has been extended by about 8 inches.

although i did have the supercharger conversion in the standerd front end before.

i used the alloy sump to hang the alternator under the supercharger.

i also had a modified water radiator made.

cost about £100.00 from serck marsten.

cool, Great technical project

 

I've got a few questions if you dont mind as i've now been thinking about supercharging instead of turbong my mi16 although still undecided but space was my main concern with the supercharger.

 

i used the alloy sump to hang the alternator under the supercharger.

1. So the supercharger was mounted using the holes in the sump in the picture below?

2. If so did it bolt straight on or did you need some sort of bracket?

3. Did the original pulley belt still fit between the crank pulley and alternator?

 

4. How did you mount the supercharger where the alternator was? any pictures?

5. Were you able to use the original mi16 manifold? and if not was it due to the fact that there was not enough room?

6. I assume you attached an addidtional pully onto the crank pulley to drive the supercharger? if so how did you attach it? and did you have any clearance issues between it and the chassis leg/inner wing?

 

Cheers

Hope you dont mind mate

hang on a minute from that picture above the turbocharger is supplying the air intake for the supercharger? But the turbo will be higher lag unlike the supercharger so that doesn't make much sense.

 

Surely running the supercharger into the turbocharger inlet would speed up the turbocharger and produce boost earlier. Or even better to have two boost pipes from each charger into the inlet and using solinoids to shut one off when the pressure becomes greater in either or.

I was thinking that surely that can't be that effcient as when the turbo is boosting properly at higher revs the supercharger will have to be spilling a fair amount of that boost and will also be sapping power off the engine at the same time.

 

I always thought that twincharging e.g golf gt and delta s4 had seperate feeds into the inlet manifold and that when the supercharger had reached a certain boost level it was bypassed and the turbo completely took over higher up the rev range. The new 350Z supercharged concept thingy has a switchable supercharger that "i think" uses a centrifugal clucth to engage and disengage.

Dont think it can be by the way it looks, the inlet of the turbo just goes off to the side somewhere, the pressurised side of the turbo goes straight into the supercharger by the look of it.

 

I am prepared to be told differently though if that isnt the case, though i cant see how it would work currently.

 

Edited to add: arrghh i'm confused now, there must be another pipe of the back of the supercharger that we cant see that snakes round to the inlet of the turbo.

turbo looks like its feeding un-cooled air to the supercharger which will then force it into the intercooler then into the inlet...

how would you bypass the supercharger though as its constant to the engine. you'd have to find a way of shutting down pulley to supercharger after turbo is spooled.

[bales 1]

Nope I am definately being stupid, the turbo must be going into the supercharger as the pressure side doesnt go to the inlet manifold and not even into a intercooler.

 

So I stand by my original post, pheww that was confusing for a bit

[Dream Weaver 2]

Interesting project, and amazing work

 

The turbo is defo supplying the s/c in that pic tho

[madspikes 41 1 Cars]

Very intresting.

 

If my install 1/2 as good I will be chuffed as nuts! The engineering looks fanastic! Its an intresting concept, supercharger and turbo. Talk about having you cake and eat it! Most people are happy with either a charger or turbo!

 

More pics and details...

 

Mad.

Yeah this is done by a centrifugal clutch sometimes, not sure exactly how though.

[welshpug 1,657]

same as an aircon pump, an electronic clutch, just like a Mk1 MR2 charger has

personally its interesting but slightly unneccessary on a lightweight FWD car. for a mid mount or FR car it would be brilliant... hats off for the work though..
