Pistons for supercharger

[Peter.K]

What would be a good compression ratio for a supercharger?


Car is a Clio 182.

 

[Jonny1*2]

didn't know you could get a supercharger for the F4R. How much that setting you back?

 

[A18XHO]

you can charge/turbo anything. Just needs customs parts and stuff and alot of money. don't know about the pistons or anything, would have though low comp 1's

 

[Mark One]

I would estimate about 9:1

 

[Andyman]

Contact pmurray or Ben R.

Supercharger kit is well under development now.

Feature in next months French car mag too

 

[Peter.K]

Thanks for the replies, Ben is on holiday so they'll have to get there skates on if they are going to be in the mag.

Nobody is giving any prices out yet.

Feature will probably have been done already im guessing.
Mags out this Friday lol

depends entirely on the power you ultimately want

 

[darinius maximus]

What about a stacked head gasket ? I imagine the 182 bottom end can take some greif before blowing up, unlike my Dci

 

[Andyman]

If your gonna run massive amounts of power over stock or high boost etc components are going to be pushed nearer their limits.

Common sense is to have over strenghend parts, rather than parts working towards their limits

 

[stan*]

Wossner make 8.5:1 off the shelf, so that would be the obvious choice.

thicker headgaskets/spacers are never a good idea...

agree

 

[Andyman]

Out of interest, does anyone do a uprated crank for the F4r ?

 

[mini-valver]

No need, the crank is pretty good apparently.

 

[shumoboi]

try farndon...they do parts for most things.

 

[ditz]

such a vague question depends on what you are after really ideally you want to keep the cr as high as poss it depends what final outcome you want

 

[Peter.K]

I would be wanting around 280 at atw

 

[Andyman]

280 ATW

This way to planet earth ------------>

maybe you misunderstood, looking at the above reply you seem to think i was on about suspension.


ideally i would like to fit new uprated pistons/conrods into a F4R engine that could possibly have a supercharger strapped to it, so if i was to change the pistons what would be the ideal compression ratio for the F4R, i'd like around 280 ATW.

if thats nocked you of your perch make sure your sitting on the ground when you hear what figures are being made.

 

[Peter.K]

yes i know the clutch will have to be uprated.

 

[RSTuning]

I went for 10:1

8.5 is too low, it only makes 0.2 bar at 4k so it would be crap to drive.

Ours is about 265atw now, still stock.....


BOOOOOOM lol

 

[lewisredfern001]

y dont you buy a supercharged v6 in mars red????

see for sale section

 

[Andyman]

if thats nocked you of your perch make sure your sitting on the ground when you hear what figures are being made.

AWT are developing a s/charger kit. Current bhp figure i last read on here after lots of mapping and testing was something like 270 ''at the fly''.

You come on here asking questions about pistons and claims of 280 ''ATW's'' seems a bit optimistic to say the least.

Good luck to you though

who makes the pistons, where from and how much?


Keep on mapping.

nah he's right, you dont want to lower CR just for the sake of it, too low and you'll lose power, but not low enough and you wont be able to carry enough ignition timing, and thus power.

ideally i would like to fit new uprated pistons/conrods into a F4R engine that could possibly have a supercharger strapped to it, so if i was to change the pistons what would be the ideal compression ratio for the F4R, i'd like around 280 ATW.

280 at the wheels is a lot but it's not out of the relms of posibility if the engine is built right. Would certainly need be a very carefully built engine rather than just throwing a few parts in though, 8.5:1 would probably work quite well and as said they are available already for turbo conversions.

We all like to dream don't we.

 

[deltav]

ohh for a supercharger kit that keeps the aircon though. cough cough

 

[sideways danny]

ohh for a supercharger kit that keeps the aircon though. cough cough

yeah, wonder who could do that

 

[kpowell911]

lolk @ running 280bhp through the front wheels of a Clio!

Just put your Clio on ITB's witha a nice 220bhp, Or buy an Evo.

 

[deltav]

yeah, wonder who could do that

nobody. im sure it cant be done

come on girls don't be shy, you now you want to tell us.

haha I've giggled the bait.

 

[deltav]

im thinking you already know peter. ive never met you but i know you know. thats all im saying on here.

How do you know i know and what do you know that i know:rasp:

 

[deltav]

cause i know everything :rasp:

Keep on mapping.

JE custom, 83.5mm due to my bores needing a fair bit off.

Pistons will be approx 450-500 quid
