Lot of work gone into that - looks nice. That waterproof megasquirt box is good, I took the easy option and fitted mine where the radio would normally go on a classic (next to ignition key)stirlsilver wrote:Hi Everyone,
Here is a summary video I shot the other day. If you are interested and have 23 minutes spare, check it out. Again, thanks for the advice, it is appreciated.
Would reccomend you brace those hard oil lines to the engine as they will move around too much and break.(i'm sure you realise that)
For my turbo water feed i cut into the heater circuit - which seems to work fine. I was considering an inline pump as well, but never bothered. The coolant is more for stopping the oil cooking/burning up when you stop the engine, rather than keeping them cool whilst driving (the oil keeps them cool)
Not sure if I saw your oil drains from the turbo's - they need to be big and straight down to the sump. I used JIC12's

Hello everyone, I wanted to share some more progress photos with you.
Bonnet modifications undertaken. Amazingly the engine fit without needing to cut any of the structure of the bonnet. I thought I was going to need to do some major surgery!
For the scoop I did some 2D CFD modelling to see where I should place the entrance of the scoop.
This is where I need to capture the free stream air.
My way of achieving a seal between the fans and the bonnet. Some more work is needed to seal some of the gaps but it worked quite well!
Some work done to try one scoop arrangement in CAD.
Here are some data logs from some of the tuning I've been doing. Below was a run I did with the boost controller turned off. Closed loop boost control is something I'm yet to program.
I trialed having the boost controler on an open loop configuration. Basically relying on the springs in the TD04L turbos to regulate boost. Based on the data below, it looks like they are set to 5psi.
One thing I think I need to do is probably look at the ignition map now as I think the engine could do with a fair bit more ignition advance, given it is LPG.
Here is a very short video of an updated run.
