My water temps at the highest before this work were 90 .
have your fans never cut in? they come on at 96 and the stat only starts to let water into the rad at 88 and isn't even fully open at a genuine 90.The old MBE used to sit the guage at 90 regardless if it went higher, thats the point Chris was making.
but your point is you now have full visability so will know exactly what is happening in future and it will be recorded ... i dont think having water cooled oil is going to be an issue.

You could replace the gauge with 2 lights. One to say it's warm enough (although of course that should run off the oil really) and another to say it's all going wrong.....I thought the fans didnt cut in until 98?
Optimal running temp is 96, gauge shows 90 at all times until it gets up to 106 then the needle jumps round to 120, but i suppose your new ECU will be controlling this signal to the gauge now? So in theory the gauge should show your accurate temps?
I understand what you are saying about airflow, it will get forced out, but that is the problem that is exactly what you do not want, because to force out it means a pressure build up at the rear of the clam, this stalls airflwo from front of engine and also stall air passing through IC, because the air pressure builds upin the whale tail and go round the back of the IC to escape this stalling air passing through the IC, plus you are creating even more drag on a car that was already bad...think about what i have said some more.. running optimally and cool and efficiently are completely different things to just monitoring for hot spots..

Have given lots of thought to creating better airflow, and you could be right, but I am trying to solve this problem without changing the look of the car to much, so by monitoring where the hotspots are I'm hoping to only change what is totally needed. so hopefully all the info we collect will show us what and where any probs are, then we can decide how to solve them, and what changes are needed.

What!!! skip giving my secrets away already;), Hi Rob, cool is def the way forward, have you done the tunnel mod? And some cleverly placed vents under engine compartment should help in a big way. New Ecu is a must IMO when you running non standard power, MBE is far to slow to keep up with our cars.
700 seems pretty mad cant wait to see what it feels like but it's not really about power at this point, it's more about control to help with reliability, the system they have designed and built is amazing, I'm already using it in my Caterham R600 superlight, R, only with different software inside the F88 , it's been faultless, the car hasn't missed a beat and is prob as quick as the Noble, so I know it works.
Can't wait to have a go now, if your around when I collect it, come and have a passenger ride no doubt it will scare us both silly..
Thanks Craig, being scared silly is a very generous offer. My car is at bespoke at the mo, so maybe our paths will cross in a timely fashion....I'll no doubt talk myself into a new ECU sooner or later!! Tunnel cooling mod plus vents does seem like a sensible way forward. It's great having your car blaze a trail or two on some of what can be done!700 seems pretty mad cant wait to see what it feels like but it's not really about power at this point, it's more about control to help with reliability, the system they have designed and built is amazing, I'm already using it in my Caterham R600 superlight, R, only with different software inside the F88 , it's been faultless, the car hasn't missed a beat and is prob as quick as the Noble, so I know it works.

Well started her up tonight, and she sounded completely different a lot more throaty, I was amazed you could hear the diff of how sweet she running now to before, the engine is so smooth, the response is instant, they made a few adjustments to the idle ie tick over, it was set at 1200 rpm , great for track not for road,so we agreed on 1050 rpm.
They also re gapped the plugs so now it doesn't blow the spark out at high boost, so now ready for the rolling road,
At a later point I have been told its better to change the plugs and coils to a higher spec but at 160 each coil they can wait till the first service.
So now Skip is finishing off all the new wiring and power cut off switch assembly, plus after moving all the important electrics to inside the car is inc the ecu, Skip is boxing it all in and covering with the same carpet so will not be seen, just means I've lost some storage space.
Should be on the rolling road in a couple of weeks, I will take a video of the session, and show all the final results results and the final settings that we have mapped in all 9 cals.

Hi gents, an update on progress, and a few more pics.
The rolling road went great, she did still blow the spark out on the top power run with max boost,
but that was fixed today by replacing the plugs with a new type then having them machined.
she now has 8 settings, starting at 460bhp the last one being 690bhp, calculations showed that 716bhp was the max, the next thing at a later date will be the coil as that really isn't up to it. The rev lmtr has been set at 7200 rpm except for the last 2 wich have been set to 7600rpm.
here's a few pics of the new dash layout and cal switch.
The ecu and fuses, relays ect have been moved behind drivers seat,.
Few more pics of Skips great handy work.
Would like to say thanks to Skip at Bespoke, for all his hard work and great craftsmanship, his standard is exceptional, he has put everything together and helped with the development, also thanks to Terry Radbourne, Bourne Racing , for all the help in the new life system, and in bringing his race technology and putting it in my car and also helping in the development the results have been outstanding.
Picking her up tomorrow, and weather permitting, will hope to be at Silverstone on Sat 17th, you know might even go in the wet, just to see what it feels like, and how she handles in tough conditions, will be a good learning curve, of course I'm not going out if there to much standing water, damp to wet I'm thinking. track conditions.

Thanks guys its been long and stressful, now to see if its been worth it.
Hi Andy, It showed that on the high power map the loss was just over 40hp to the wheels, which really ain't bad when you consider that most cars will lose 70 or 80.
How's your beast coming along?
Hi Graham, I thought I would wait and see what the car felt like without the traction control on track, then I can decide what level to have if any, as I really prefer to feel the limit rather than having it controlled, it makes me feel like I never really sure where the limit is, maybe because I'm not used to it as all my cars have been lucky even to have abs.
Hi Chriss, Sorry not got pics of the rear clam yet, as I'm having a spare made with these air scoops in, and rear arch vents with some other changes too, my idea is to put this one on for track days and the standard one for the road.
Cheers guys
Craig
