If I happened to have the chance of vidoeing/photographing and interviewing the owner of a UK supercharged Gen4, what specific points/questions would you like me to ask. 

I know what a supercharger is but my knowledge ends there and I would want to make it something that people want to see.

Give me a list.... 


 


1. What kit and type of supercharger is it?
1a. What was included in the kit, intercooler/charge cooler, cold air intake, etc
1b. Who supplied it/where can others buy it?
2. What boost are they running?
3. Are they running on high octane fuel, i.e. superunleaded?
4. Did they install themselves?
5. Who/how was the ECU mapped?
6. What sort of MPG are they getting (OBC and/or real world calculated)?
7. How is the throttle response?
8. Have they used it off road, if so how did they get on?
9. Any negatives or things they don't like about it?
10. What sort of noise does the blower make, is it loud?
11. How do the factory standard brakes cope with the extra power?
12. Where do they feel the biggest gains are? e.g. part throttle or wide open throttle. Low/mid range punch or top end power?

l think the benefit of a supercharger (over turbocharged) is the more immediate pickup and low RPM power.
So l would expect to see the Jimny feeling much more lively.
Joking aside, l am genuinely interested as to how it will handle the considerable extra power from
the supercharger, particularly under conditions of reduced grip on the road, being a lightweight effectively RWD live axle vehicle with fairly narrow high profile tyres.

I'd be interested in seeing a before and after dynograph.

Interesting. Not a lot gained at the bottom end, but the supercharger keeps the torque rising where the standard engine plateaus at 3,500rpm, leading to a big difference at the red line. This will really change how the engine feels above 3,500rpm. Worthwhile for people that are finding the engine a bit flat at higher RPM.
