Supercharging the 4.7 Gran Turismo or MC Stradale

[mischaRS]

Guys, I contacted Novitec in Germany re their Supercharger conversion and they have ceased offering the kit, presumably as it was extremely expensive@approx £35,000!
My 993RS is supercharged by Ninemeister with a TPS kit, at a fraction of Novitecs cost !
This got me thinking, so I contacted Richard Albans at TTS Performance, and he was helpful.
In short, it is possible, but he would not start building a Rotrex kit unless all the development costs are paid , basically up front.
Richard thinks a fully fitted , remapped kit, would be somewhere around the £11,000-£13,000 mark, but he would need at least 10 people to show interest.
In black and white,to start the ball rolling, we need enough interested members to make the project worthwhile.
Methinks a 600 bhp Gran Turismo would certainly see the ridiculousy cheap selling prices suddenly start escalating ?
And I am certain, given time, at a fair price, a lot of kits would be sold

Wow, £35k seems a lot. I know the previous owner on my Chimaera had quite a large a Rotrex Supercharger added with engine upgrades/rebuild done and the cost was about £18k I understand. Which seems decent value in comparison.

A stock Chimaera 450 was allegedly 280bhp from the factory although most suggest the factory claims were often never realised on most cars. With the Supercharger added and engine upgrades/rebuild it has been rolling road tested at circa 490bhp so seems a good bang for buck in comparison.

Can't see 10 people in the UK interested unfortunately.
These projects only seem viable in the US simply because the population is 5 times bigger and many more cars sold as a result.
So its the equivalent of just 2 people being interested in the UK, not 10.

Been working with another firm and finally have an Ecu remap that is not purely guess work. The coding has been cracked to get to the actual setting that make a real difference and the conservative limitations removed which results in dramatic low Rev torque increase.

I have yet to get my ECU back for my Strad but expecting an actual real world difference and not just a pretty graph telling me I have more power.

remapping can certainly make a huge difference, even on NA engines.
AV Engineering recently remapped the ECU’s on my 360 following an engine rebuild. It simply is not the same car to drive. It isn’t just a pretty graph, I drove that car for 19 years before the remap so I reckon I’m fairly qualified to comment on it.

Oooh this sounds exciting. Will the remap help us hear your pretty silent car any more too?

 

[Ewan]

I’d say the chance of finding 10 people who want to spend a five figure sum supercharging their GT is next to zero. I suspect you’d be doing well to find just one other person to actually commit.

 

[Ewan]

The ECU remap, on the other hand, at presumably a few Pounds, could well have plenty of takers.

 

[conaero]

I’ll crack in and get mine done and give an honest opinion

 

[mischaRS]

Matt, please book me in for the remap, that might save a lot of money !! Thanks

 

[conaero]

It’s not passed development test yet. When it does, you will know on here.

Presumably the limitations on low rev torque are there to look after the transmission?

 

[Ebenezer]

What about the 4.2.QP?

Dunno whether this map would only do for the MC, but the ZF can take more torque. As I've found out

Sounds promising

 

[Gazcw]

Sign me up when done if it works on qp too.

You know the only true test is a side by side with a non-mapped car don't you

You think any similar decelopments with the ECU tuning would apply to the 4200? I feel like those cars are potentially comprised in terms of ECU tuning, judging by other things like the very restrictive exhaust.

It’s a different architecture, Gransport is Bosch ME5.1.2 and the Stradale is ME7.1.1. The same principles apply, but the maps will be different so not applicable.

Would the car have to be in the UK for either alternative (supercharger kit or just ECU)?? I'm assuming any local tuner could fit a complete parts kit. Regarding the ECU, I'm pretty sure that it could either be sent off, or connected to a PC and flashed remotely from anywhere?

Certainly interested, especially if it can be done remotely, and is reversible. Well done to those playing with this!
