Remapping a supercharged car...

2nd November 2009, 20:50

Probably not the best place to ask but i can't seen to find much detail online about it.

Basically (and don't start with the gay jokes) i was thinking of getting a Mini Cooper S as my next car but didn't want the newer turbo'd engine as it's the same as my mates old 207 gti engine and he had no end of problems with it, so has put me off. Plus i love the supercharger whine

Just wondered if you can remap the supercharged engine with decent power gains? and what it compares to the turbo version? Which iirc remaps to about 210bhp

2nd November 2009, 20:53

You'd have to remap it if you supercharged a previously n/a engine.

Edit: Just realised I might have misunderstood, do they come supercharged as standard or were you planning to charge it yourself? I think generally speaking the gains given from remapping a charged car from standard are not going to be as great as a turbo'd car.

Yeah youll be able to remap it with gains, theyre never at their limit from the showroom. How much Im not sure.

If you want a Cooper S though, get the old one. Much better drivers car

Comes as standard. A decent remap will see good power gains.

Dont wory about them being

mate. i would have one over a sax in a heartbeat lol

Yea the cooper s is either supercharged (01-04 plate or something) or turbo'd (04+ plate)

Just seeing if people would know of rough figures compared to the tubby version

i thought it was harder to get any real gains off a supercharger.

2nd November 2009, 21:28

Superchips reckon they can only get 7bhp from the supercharged 1.6 170bhp version?

Not the best of places though.

p-torque do generic remaps for them

2nd November 2009, 21:37

good fun car to drive!! gear ratios are so short!!

2nd November 2009, 21:42

Get the works pack upgrade for them. Think that includes different pulleys and slightly bigger charger, and a remap to adjust fueling etc for the higher boost from the new bits

3rd November 2009, 01:35

and how much would that cost me? lol

seems like maybe the tubby version is the way forward if i wanted big gains

3rd November 2009, 01:41

you will have about 25% to play around with mate. its a case of balancing it out for economy and performance which is basicly what Mini has already tried to optimise so your only option is full open remap so it pushes loads of fuel via the injectors but I cna see you having overfuelling problems straight away and it will run like shite.

best bet is larger injectors, lighter pullies,stronger cam belt & a remap all done at the sametime.

tbh the question is are you used to driving higher powerd cars? thought id mention that as its a totally different driving experince. plus you got to think in the long run. can you afford to keep it on the road.

either package your looking at over 1,500 easily!

Yea i've driven my mates LCR pushing 270bhp quite a lot, but i'm not a fast driver anyways. Just nice to have the power there when needed

And i live at home with the rents and my only bills are insurance and phone which add upto £100 so got rest of my wages to blow on petrol, food, sex etc lol

dont get a tubby then lol if you drive slow.

turbo's hate slow driving. scoobies,evo,skylines all get the same bearing problem within the turbo's so you have to either replace or get rebuilt. which is a waste of money. im lucky where I live there is loads of back roads so im able to open it up when I get the feeling (shame car aint on road at moment tho

..)

turbo cars have loads of problems if not kept upto scratch. oil cooling issues,turbo, wrong fuelling/boost etc etc.

what I laught most about is when People get a boosted car and aint got a clue what boost to set it at, and then they go out driving it on test runs at different boost levels the problem there is your fucking the engine up whilst your doing it hahaha. so what ever you do make sure you get an engine built for say can handle 400 bhp But your only pushing out 250bhp that way there is 150bhp area the engine aint getting which results in less stress on the engine block and componants

.

the Hks intercooler I got for the Liner is one for a 800bhp built engine. il only be pushing out around 400bhp though!

hope thats made sence hahaha.

Yea that makes sense, when i say i don't drive quick, i mean i don't have to over 18 cars on the way to work to be happy. But when the road ahead is clear and safe, i can be persuaded to put my toe down

I'll have to do some more research into it, aslong as i can hit 200 bhp i'd be fairly happy

170bhp standard in a cooper S

honest mate 30bhp will do SFA. you'll have very slightly faster pick up but not much extra top speed due to they have short gear ratio's. if anything you will put just a bit more strain on the clutch,gearbox.

and for what you will have to fork out to get that extra 30bph its not worth it mate

IC, smaller pulley, panel filter and a remap on a mate's old one, gave something like 215bhp on the rollers.

Just watch out for cooling issues, he had to have a rebuild after piston 4 decided to melt. According to him, it's quite common, even on standard engines, due to it being too far away from the water pump or something.

so a larger pump is needed along with a bigger mocal oil cooler.

even then the internals will still melt the rings need to be thicker on the pistons and the cavity wall inside the block would need to be thicker so it can take more heat/friction. even then once you have got that sorted out you will put extra strain on the crankshaft and cams lols.

boosted or superC'd cars are a nightmare unless done 100% correct.

A remap on a S/C engine will not see the gains that it would on a Turbo.

The best thing to do would be to match smaller+lighter pullys with larger injectors and a remap and depending on the power you want a chargecooler.

Hmm then seems like alot of work, kinda being a noob i thought maye you could do simple remaps like on turbo's to get bit more power, seems like the newer turbo version might be best bet

il give you an example mate (which is a real one)

my dad has a superC'd jaguar Xkr 4.2
he spent £345 to get the lighter pullies and it resulted in him getting around 25-30 bhp more. he also changed the belts to thicker ones to. he has told me and I have driven the car myself all you feel is a smother transaction with torque distrobution. in other words the engine runs alot smoother and seems to run easier/tighter. but other then that id have said its £345 wasted

http://cgi.ebay.co.uk/Jaguar-XKR-XJR...item5d23c5ef29

my dad dint need to get his ECU remapped either as the jag ECU automaticly readjusts itself to the changes.

saying that it is a big engine 4.2 so for say a mini cooper s id have said for the same sort of part it would be around £150-200 then there is labour in fitting it correctly and you would need to get a remap aswell so before you know it thats easily £550ish in total.

right, i know quite a bit about these cars as they are on my list of contenders for my new car...
the 1.6 supercharged engines in the mini have HUGE tuning potential, 250bhp+ is considered fairly mild.
You can see over 200bhp with the first stage of tuning. Its not so much in a remap but changing the pully wheel on the supercharger puts the boost up and therefore more power... changing the plugs and such like and getting 1320mini to do a check on the car is advised.
With an upgraded airfilter, exhaust, manifold and the map tweaked slightly 230bhp is possible and then;
with a cam and some headwork, injectors and a further map, 260+ is achievable...

oooo you seem like the guy to talk to! whats the ballpark price for 220-230bhp figure?

3rd November 2009, 17:15

first stage of tuning is around the £300-400 mark for the pully wheel, belts, other bits and pieces.
Around £1200-1400 will get you 220+bhp(and thats with a top mount intercooler, forgot to mention that before).
IIRC someone spent about £1900 on their cooper s which seems like a lot but from the origional 165ishbhp it went up to 250bhp and try to get that kind of power increase from a N/A engine....
