Sorry to be critical,

The switch you are using for I assume selecting the 8 different setting is a very cheap RS part by the look of it. wink

I had exactly this for by variable boost so changed it to a nice Ally one. looks much better.

Other than that great work and what a result.

Still waiting for an answer about the lamina flow oil cooler though coffee

Craig - can we see the RR graph

40 hp loss seems a bit low, what gear was the test done in ?

My losses were measured as 50bhp so its nice for them to be confirmed as realistic.

Can you tell me what the latest situation is with the strengthened gearbox?

Thanks

It was done at Abbey's hub dyno.

Mr Bond I'm sure I answered on page 10 and may of left a link for you, the one that I have fitted smile
I like that switch, its unassuming, wasn't cheap with the connectors, the light was extra. wink

He he, a link you did leave but then I asked this:

"Where have you plumbed it from the water side and did I here that Pro alloy are going to do a kit?

I've always liked this idea and as I don't track mine that much it seems ideal as it does take a while to get the oil up to temp.

And I suppose you could have one in the other pod for the gearbox right? Or even better that pro alloy do a twin core so you can have box and engine in the same system?

I only commented on the switch because I see them all the time on cheap electronics and in house test equipment.

Each to their on on that one then smile

Mate after today, don't wast your time or money on changing oil cooler, stick to what's proven, Motec front mounted.

Hi Duncun, nice to meet you today, just a couple of stupid things that cost me 90% of my track time,
The first was the safety setting on the oil pressure sensor which was set to high, so the ecu kept shutting the car down after Woodcote, we then fixed that and I finally got some track time, then the coil burnt out due to oil pipe getting so hot through the oil cooler not cooling and it runs by the first coil and the heat burn the coil, not having a spare meant that was the end of the day, which was a real shame as she was really going well at that time and we had only just got to number 3 setting of 8.
Thankfully it's all a simple fix that even I can do, But back to Bespoke for the oil cooler being changed.

Morning Craig , very disappointing the problem you encountered but I guess it's all part of the development !!
140 degree oil temps on such a cold day was very high and I would get bespoke to check to see if the lamnova is working at all !!!!
After you coil breakdown I'm going to buy a spare to carry in my spares kit !!

Hope you get it sorted .

Agree with Tux that it's part of development but pleased the issues aren't too serious, hats off to you in giving the car it's first running in public.

Sorry to hear of the problems, hope that's the worst of it past now.

Deffo agree with front mounting the cooler, those temps are high, as if the cooler isn't working.

On trevs rollers my losses were 60bhp, so if there are 40,50 and 60bhp being quoted it must be somewhere in the middle.

most Dyno's do a coast down to measure the transmission losses

the problem is the engine is disconnected from the gearbox and there is no power transmitted through the gearbox !!

if you measured 100 or 1000hp on the power run the the loss is the same every time LOL

the only real way to find out the losses is to take the engine out and test it on an engine dyno at different loads, then perform the same test on a load bearing chassis dyno - the real result will be much higher than 50 hp at full load and much less than 50 hp at light load

FWIW I have a smaller Laminova on my 3.0, and oil temps have never gone beyond 90C on the hottest days with a/c on. No track time yet, though.





Edit: Mine is a single turbo conversion, so there is no red hot cantaloupe next to the cooler.

That looks cool (excuse the pun). Will it work with the twin turbo. Don't see why not. How does it connect up?

Details please.

It might look good but it did NOT work for Sundance yesterday !!!! He was very lucky not to kill his engine !!!

It will be interesting to see what bespoke say thought .
