Supercharging Willified Valver

[Smokey]

Just toying with a couple of ideas at the moment and was after some comments and opinions on Charging.

Has anyone charged there Hybrid/Williams or Valver? If so what sort of BHP/Torque increases can be expected?

How much am i looking at for the Kit?

How much to fit the kit and set up on RR?

Is there enough space in the engine bay to fit?

How reliable are these kits?

Thats about it for now, will no doubt have some more questions later.

Thanks

All i know is that you best have deep pockets for the fuel bill ;-) Would be cool tho!

 

[Smokey]

Fuel bill..............Pah, thats the least of my problems

 

[Winston]

I wrote a big reply out and my computer crashed lol

To sum it up.....speak to BenR

Superchargers rule imo

dont know if theres a kit commonly available, there prolly will be just ive never heard of one.

to be honest I would like to see it done, but I wouldnt recommend anything like that, it would totally change the characteristics of the car (although not as bad as a turbo im sure...). id stick to N/A tuning and take it to Ben and Andy for some TB action... its worth it for the sound alone Smokey... it really is something else

 

[6secClio]

wow thats what i was thinking of getting done

god that would said well nice

 

[Smokey]

That is a minter Winston, but how bigs that SC

Im looking at a Rotrex SP30 74 http://www.rotrex.eu.com/files/SP30_installation_instructions.pdfhttp://www.rotrex.eu.com/files/SP30_installation_instructions.pdf

I know what you mean Jesus, but the cost implications are a bit high on the TBs to be honest.

I will speak to Ben later see what he thinks

 

[Winston]

Lmao @ the bonnet

CooperS chargers are cheap as chips.....eaton M45 iirc......Just need to blag ben to make a manifold lol

 

[unofficialPete]

I seem to remember seeing a supercharged valver on autotrader a year ago, they sent the engine over to Sweden or thereabouts for the work!

 

[TheJesus]

i dont really know a lot about charging, what exactly would be needed to get one to fit and work?

we talking stand alone engine management too? Craigs car would be able to fit a huge charger in it

 

[Daz]

Theres a supercharged Dimma around - that silver one!

Didnt Dimma do a couple?

 

[BenR]

Smokey, charging is expensive IF you go for new chargers or fancy chargers.

Rotrex and any other type of centrifugal charger will require an intercooler setup, adiabatic efficiency isnt great. And cost a bomb.

Id plump for a positive displacement charger, a sprintex screw or a Lysholm.

However, you can get the OE cooper S 5th gen chargers for very little now, £400. Giving you more than enough for 200+, earlier ones are limited to slightly less but cheaper. Would require fabbing up a manifold, no intercooler needed. Management wise id have to reel off a few options to you.

 

[Alan_C]

I was considering a charger for my 172 aswell would it be possible for that engine too?

 

[BenR]

certainly.

The major problem is the belt drive assembly as there is a total lack of space on both cars, but nothing that cant be sorted.

 

[Ben j]

easy! cost about £5000 at least tho. remove the power steering! get a rotrex c30 74. (sps are old spec now... but i do know of an sp30 74 for sale tho for about £600) same as on mine!

put the charger unit where ya powersteering pump was. ud need low pistons inserted.extra injector or 2. mf2 unit to drive them. custom intercooler and rad made up. some samco and some chrone straight bits. and an adaptor to fit ya intake...

5 grand!!!!

if you went ofr a budget build then nowhere near that much.

Like i said, wouldnt do a rotrex.

Wouldnt have an intercooler.

Wouldnt have extra injectors

wouldnt dump PAS!!!!!!

No need for low comp pistons.

 

[Ben j]

y budget build it? u want BIG power!
i know they didnt have the best name but the new rotrexs are used on the kossenigggnenngoiiiggg thingy arnt they? so cant be bad?

 

[BenR]

doubt he wants to spend 5K!

And if you want BIG power its going to cost more than that.

And top fuelers dont run centrifugals...

intercoolers and all that, whats the point.....if you dont heatup the charge than you dont need to cool it again.

 

[Ben j]

how can u not heat up pressurised air?

 

[Smokey]

I was bidding on a Rotrex SP30 74 on ebay which went for £625 as i missed the end of the auction grrrrrrrrrrrrrrrrrrr..............................

Anyway, I will catch up with you soon ben to discuss the Mini charger option.

I will be happy with 200 ponies

Oh and i dont wanna lose my PAS as im a girly

by not compressing it in the charger.

They are called positive displacement chargers.

 

[Ben j]

and wats that do then?

 

[BenR]

move air, not compress it.

 

[Ben j]

explain in a non technical simple person way for the likes of me......

surley it must compress it?

 

[Alan_C]

BenR if its not too much trouble is there any chance you could pm me a list of parts id be looking for to supercharge a mk2 172. cheers

 

[BenR]

ben.......try google.

But in laymans, a positive displacement draws in air and moves it to another place, it supercharges because it moves more than the engine can consume naturally, so therefor there is boost on the otherside of the charger. They are generally called roots or screw chargers.....they literally just move it.

A compressor type like you have or like turbos, the compressor wheel inside the housing compresses the air, adding heat, before it exits the housing.

 

[Ben j]

i seeeee.. can u get as good power out of them then?

 

[BenR]

yup........8000bhp if you go for one big enough.

 

[dannyboy]

lol 8,000 BHP, would have to be soo big it went in the boot!!!!

 

[Ben j]

can i have a 7000 bhp clio then please?


-(see im not ott and wanting 8000)

 

[BenR]

got the cash?

 

[Ben j]

ummm .. no can u pay? and ill tell everyone you did it and get you lots more business.... also i no longer have my 16v so ud need to buy me one of them too

 

[BenR]

hmmmmmmmm.................................ok........in my mind.
