Things haven’t quite panned out as I had envisaged, but that’s always the risk when not going down the “off the shelf” route……
Putting it bluntly there have been some issues with being able to progress with the pre-production big turbo kit. It has been suggested that the current manifold design may need some alterations made around the collector (which is where the five tubes from each exhaust port meet the turbo exhaust side). This will take at least 5 weeks to redesign and fabricate. Due to this, other competing workload and not enough hours in the day, I have been informed that it will be unrealistic to expect any real progress to be made on this until the Autumn.
Believe me, this is disappointing but it is what is it.
So I had a decision to make…… wait until the Autumn to start, and let’s be honest that could drift again, or take a different direction now. I chose the latter.
I don’t know how this will pan out, but until I try then I won’t know.
I have now decided to have a hybrid turbo created based on the OEM housing and manifold, so I have commissioned Litchfield and Turbo Dynamics to “crack on” with this.
I have done a fair amount of work with both of these companies in the past with hybrid turbos with really good results, so it will be interesting to see how this goes.
Ideally I never wanted to go down this route as this will fall well short of where I wanted the car to be powerwise, however, it’s more about the journey for me than any single result at any single point in time.
In some respects it fits better now into the Staged approach I prefer to take, being more of a Stage 3 conversion utilising the stock turbo frame.
Whilst I fully appreciate this has been done before by others, there are some ideas we’ve discussed to look at trying something slightly different to what is currently available.
I’ll still be keeping one eye on the big turbo development, but I won’t expect to be up and running properly with that until the next drag strip season. In the meantime I’m hopeful we can make positive progress with a hybrid unit.
I’ll update as soon as I start getting pictures and details back from Litchfield and TD.
