Hi,
I am planning my winter upgrades for the Daytona and the primary goal is getting my cal dynotuned which is already scheduled.
The company I am doing the dynotuning with, is a professional Race Car Builder mainly for Citroen and Renault GT Series and Rally Cars. (This is the type of company that won't let you go on a dyno without beforehand tapping all four runners of the manifold for temp sensors and lot's of other stuff)
My initial goals are conservative 300HP on the wheel (before going there I would have said "ambitious" but they teached me some lessons about what is possible so now I say conservative because I need to stay within a budget).
During the first session, we were discussing my goals which basically are shifting the power curve to a lower RPM Range for obvious reasons (it is no good getting a hell of power at 5000 RPM with only 1000 RPM left to enjoy it). My condition was at stage 1 using my own SMEC and only in stage 2 getting a custom ECU done because for the money I am going to spend I want to learn things. So I am happy to live with some HP less for the benefit of having understood why I am going to have more power with my current configuration.
So the plan goes in 3 stages:
Stage 1: Getting the safe max out of my current configuration using SMEC
(The results out of this I will share with you end of october)
Stage 2: Getting a custom ECU (Magnelli) initial tuned for my current configuration
Stage 3: Building Engine, Going 16V and raising the RPM Range for more serious power
Stage 1 and 2 this year, Stage 3 whenever I have the money
Until here the background.
So we discussed various ways and options for a turbocharged car.
One point they raised is that it would be worth a consideration to complement the Turbocharger with a coupled (via Clutch) Supercharger.
That would allow me to use a bigger (not a monster) Turbocharger developing it's full potential let's say up from 4500 RPM and until then cover my PSI needs to get accelaration and smooth powerband off the line.
They would engage/dissengage a clutch for the supercharger once a pressure limit is exceeded using the MAP and RPM signal to determine the right moment.
Has anyone ever done this yet? I know there are folks that Supercharge N/A cars but I am referring to complementing the Turbo with a Supercharger?
I found this an interesting idea - even though this is not cheap at all and in my case earliest at stage 3. But it has my head working right now.
Any thoughts on this Supercharger+Turbocharger Configuration??
