fancy the idea of a supercharger kit... dont need any silly horsepower numbers, but as we all know, keeping n/a comes at a cost if you want even 50 hp more...
my honda engine is in my kit car (weighs 600kg), which is why massive power like 400hp+ would be a waste.. 300 at the wheels would be rather nice tho ;-)
thing is I need to keep the stock ecu, as the mot over in germany test using the obd port, and if i use any other standalone ecus will mean a fail..
i realize that when you apply a supercharger the air/fuel ratios need adjusting, so Im thinking whether or not its even poss to run a supercharger with stock ecu????
a turbo would be ok, but im not sure thats what I want for the car, as the turbo power delivery in such a light car, would send me all over the place!
anyone heard of a s.charger kit for standard setup?

science of speed stage 1 kit comes with a pre-tuned fmu thing (for ap1's atleast). i dont think that would affect the test your talking about? maybe im wrong just a suggestion to look into

 

not like this helps or anything about your questions, but just b/c it's a turbo doesn't mean you'll get a crazy amount of power. there are some kits that give you 300 at the wheels just like some superchargers. it just depends on your tune, turbo size, and psi you're running, like for example the greddy turbo kit is a pretty small turbo and usually gets you at around 320 at the wheels (still dependent on your tune and supporting mods)

 

its not the amount of power from a turbo that worries me. its more the delivery. in a normal sized car, you can normally handle the massive increase of power when the turbo kicks in as the cars weight is holding it back, and also keeping the wheels on the ground...
my car weighs about 600kgs, as soon as the turbo kicks in its going to spin the wheels in pretty much any gear, and going through and out of corners will take some very experienced foot work!
its just too much power in one go with a turbo... bmws twin turbo is a stroke of genius, a little turbo to bring you up to speed, and then the bigger one kicks in.. not sure I could afford this setup tho!

 

i feel like a supercharger will give you the power instantaneously because it gets its turbine turning from the crank. so i feel like that would more likely cause your wheels to spin than a turbo, since turbos use exhaust gases to turn the turbine, but small turbos don't really lag they just don't give out much on the high end.
but your right in the part that your car weighs considerably less than a normal car, so i have no idea how turbos and superchargers would affect your car, just basing my opinions off the cars i've driven with turbos and superchargers.
but if i were to go FI, it would be supercharger cause it's more reliable and easier to maintain, i wouldn't be worried about making a crap ton of power, which turbos are good for that.

do you have a build thread? i'm interested in your lil project car
and have you heard of the v8 ariel atom? it's ridiculous to have so much power in a tiny car haha

 

damn that atom looks good dunnit!!!
have you seen what they cost tho! the engine is a thing of beauty..
Ive seen a few westy with cosworth turbo engines, and not really liking how they handle/react to the power delivery.. dont think a supercharger is going to be particularly easy going either!
Im already considering selling my project when its finished, so that I can do it again! only next time Id buy a westy thats 2000 registered or older, as the german emissions are a lot easier then, and would mean that I could install a standalone ecu, and supercharger!!!!

 

I dont know the specifics of German emissions inspections, but you can leave the belt off the SC (not make any boost) and run the stock ECU while being inspected.. that would allow you to run a standalone EMS the other 364 days of the year.
Since you have a kit car I'm guessing the normal visual inspection does not apply since you built the car yourself.
