Supercharged Chim 4.0
Discussion
I have been thinking recently about embarking on a little project to make my chimaera a bit quicker.
This would be almost completely a diy project and it would be on a limited budget.
I have seen a few superchargers for reasonable money and wondered if it would be feasible. Normal "tuning" is too expensive and will not yield the same kind of results for cash spent, so forced induction is the way to go.
And before anyone says Buy a 5.0, it would cost to much to upgrade. Also, chimaeras seem to be hard to sell currently.
So what issues are there to consider? Am i thinking along the right lines?
Has anyone else gone down this route before ?
Supercharger type - Likely to be a roots type blower, probably Eaton M90 or M112? I would prefer a twin screw type compressor but they don’t seem to be readily available.
Fueling - Bigger injectors will be needed as well as higher flow fuel pump.
What are the options for these? Would 5.0 injectors flow enough fuel?
Boost - about 5-6 psi should be ok without any changes to compression ratio or any intercooling ?
Ignition system - should be ok standard as long as its in good working order.
ECU - remap by Mark Adams or piggy back system such as a Unichip or similar.
Would i need to change the air flow meter ?
what other parts would i need to change/improve ?
What other factors are there to consider ?
cheers

Peter,
What kind of blower do you have on the V8S ?
what pressure is it running ?
where is the throttle ? filter or engine side of compressor ?
Have you got any kind of write up detailing the system and what components have been used ?
I’m no expert, so im trying to gather as much info as possible before committing to the project.
On the subject of cost, I will be aiming towards 280bhp and 280lbft (flywheel)to start with. From what i have read it would take a good standard 5.0 or tuned 4.5 to get to this level, and at a cost of over £3,000 to change my engine. My budget for this project would be half that (hopefully less), this would be done over a period of time to spread the cost and minimize the time my car is off the road.
Am i being realistic with my budget ?
