Peugeot 207

Hi,

I want to supercharge my 207 is this do-able and what supercharger would you reccomend?

 

[pgarner]

Yes but if theres no off the shelf kit avalible then it may have to be a custom build.
just remember to keep the boost levels really low prob stay below 7psi ,compared to a normally forced induction running around 18psi (just over 1 bar), as youll just end up blowing the engine due to higher compressions in the chambers

 

[nitroangel]

okay interesting and to sort out the compression I need too????

 

[pgarner]

well if you keep the boost low nothing but youll only gain about 20bhp
to adjust the compression ether use

1. a stroker kit, mainly used to increase the displacement but lower the compression but lower the compression as a side effect
2. fit low compression connecting rods ( often shortened to conrod)
3. of your not already doing so use super unleaded ,highest ron possible, as this will help against knocking due to the higher compression

i see your looking at adding nos to the car why not just use the nitrous rather than supercharging the engine itll save you around £2k

if your going down the road of supercharging and adding nitrous are you looking at keeing the car for a good few years if so look at adding forged pistons while the blocks apart when fitting the shorter conrods

the problem with doing a lot of under bonnet work is that the compression will get too high ( way to much air fuel going into each cylinder then being compressed read the article on turbo / super chargers) ie running with the charger at even 1 bar along with the nos may be too much for the engine to take and end up with you requiring a new engine bit of a pain if your using the car daily

And a base plate wont that work?????

 

[pgarner]

what do you mean base plate ?
the only thing i can think you mean is the head gasket. yeah a thicker one will lower it slightly

your best idea would be to try and find a company that specialises in supercharging and see if theyve ever done a pug engine before they might be able to tell you what the max boost you could run without having to open the engine up. it still would give you a increase in power

 

[nitroangel]

lol it must be an SA thing thing

yeah that the problem I am the first one doing mods and no one has a clue and it alot of money to just experiment on

 

[pgarner]

yeah your lookin gat a good couple of grand for the charger then theres the intercooler pipework

have you thought about leaving the charger for another car and looking at adding nitrous it will give you around the same gains but not as much hardwork

 

[nitroangel]

yeah the custom branches come in feb then the management with programable nos then she goes on dyno to see what the result is


I think i found a solution for the supercharger

an electric one!!! it goes in my car and our pressure level is 1.256 PSI only it will never put any strain on my engine happy days *grins*

 

[pgarner]

sorry to sound down but 1.2 psi aint a lot less than 0.1 bar

i did look at these for my old civic as seen claims of around 35bhp on most cars however the rotational speed that is required to gain boost, remember as your car goes ups the rpm the vacum that it produces increases as well this means that the electric charger would have to work very hard, would have to be at a stupid speed remember that a turbo can spool at 200k rpm

 

[nitroangel]

nope I dont think you sound down..... I appreciate your imput and am finding this information very informative as a matter of fact, besides it is helping me make my decision
