Had my car on the dyno yesterday thought I'd share the result...

And a much higher result than expected!!

476hp at the wheels.

Hopefully the link to the video works...

Garrett GT3076 .64 rear housing, 1.6 bar boost on pump gas. Surprisingly responsive turbo.

Vvti really helps spool it up, my charger makes 398 whp at 1 bar and 7950 rpm but nowhere near your torque. I'm tempted to go with a gt30 or a similar turbonetic setup now

Have low boost (actuator pressure) of 1 bar and make 310kw too, so very similar result at same boost.

Big advantage you'd have with the supercharger is the engine bay temps are waaaaay lower with a supercharger.

I'm at the limit of the charger now, at 14 psi I'm spinning the charger at 52000 rpm and the next step will be swapping to a more aggressive impellor, I'm using a chargecooler setup and 3" pipework because I lost 4/5 psi with a front mount setup.

Wow, must've been a big intercooler. I lose 2psi over mine, only 2" pipework though.

Would be cool to see a few pics of your different cooling set ups!

I though superchargers always produce more torque than turbo's, I know they do lower as no/little spool/lag
how come you running a 3" pipe not 2" or 2.5? as would give a lower boost drop as supercharger don't really need intercoolers not like turbo's

you running the chargecooler constantly?

Air getting compressed causes heat, so both require some level of cooling.

I realise they do need to spool up and depends on the size of the supercharger, that what I put in post no/little spool/lag
as all depends what you are running, and same on intercooler depends what size you are running but unlike turbo's which are on the manifold which can get red hot they need an intercooler no question, supercharger don't need one as very little heat produced but again just depends what you run as some are more efficient than others
try reading post's a little better

Sigh. :roll:

I know that a supercharger has lag, read my post you can see just depends what you use, a small charger will have little lag, same as small turbo, big turbo is going to have a fair bit of lag same as a larger supercharger that's why I said depending what you use :roll:

and as for intercooler a small or large turbo will need one no matter what
a small centrifugal supercharger produces very little heat a so doesn't specifically need an intercooler unlike turbo's which always need one :roll:

Il try and upload a pic from my phone but I'm on holiday so not got access to a pc, there are pics of my original setup in my supercharger build thread, I originally used a spearco front mount with 2.5" pipework. I'm now using a chargecooler which loses about 1.5 psi across the cooler and pipework. UN cooled at 7 psi intake temps were 35 deg, at 11 psi UN cooled temps reached 58 deg, now charge cooled at 14 psi max intake temp is 27/28 deg.
