not yet , still speaking to a few different possible dealers.

Few pictures from Friday test session; car looks pretty good, front bumper is now a slightly different shape thou.

Bennett , we was running Syvecs not the stock ECU for the race. Will get the ECU sent tomorrow. Once you have paid the deposit.

3 gears limiter removal is done on a Uprev remap. The limiter isn't an opening restriction it is a response limiter in the lower gears the response between the throttle pedal being pressed and the throttle butterfly opening is slowed in the lower gears to make the car more "soft" to drive. When we remap we remove this restriction so making the throttle response "sharper".

Yes thats correct.

Euro and JDM cruise switches are different. Cipher wont work as it is only Diagnostic you need to upload a cruise map with Osiris Standard/Tuner or a Pro dealer to load the correct map.

Getting the new motor running and talk to the stock can bus system is easy. Use a Syvecs S8 ECU configure the custom can from the Syvecs to talk to the stock ambush circuit via canbus box and your dash/heater BCM will all work like a stock car. Full traction control as well.

Did the O ring get fitted this time?í ½í¸€

We could sort the problem without ordering any parts from the US. Either leave the car with us or pull the SC main bracket off and drop it to us, sime job to add the extra If you drop the car to us we can check the tune after sorting the belt slippage issues.

AFR figures look strange as the flow from the exhaust swapped over during the run. Adrian/Sam can I lay your dyno plots over each other?

Adrian, what do you think of the car now? Power delivery nice and smooth , throttle response good? Sam, yes we can get these nailed quite nicely now , I think 360lb/ft is the safe limit for the motor torque wise , SC is far safer than Turbo charging as Turbo makes a lot of torque even at low RPM conditions this is what kills the stock rods. Sc makes boost in relation to RPM so you never get the big wave of torque like a turbo motor. I have tuned a few to 420+ hub bhp with no issue s on the stock ECU, we tune the torque/power out of the mid range with cam work not retarding the ignition timing so not causing any high Exhaust gas temperature's which Is can/will cause issues. Cant wait to tune a motor with Syvecs S6 thou think we could go for 450+ hub bhp and limit the torque mid-range torque by not opening the throttle fully until over a certain rpm. This will help keep the motor in one piece.

On a FI car we have found from testing a thicker plenums spacers works.

They do fit but they take time to get aligned nicely.

they are the correct length you just need to make sure the pipe are aligned all okay.

copper slip or white grease on the threads will and does stop corrosion, spent a few years in the Motorsport game building cars, my forte was plumbing hard lines/flexible, re usable/crimped fittings. when I had to remove the alloy fuel adaptor to fit my fuel pressure gauge, found PTFE in the fuel lines not good, manage to pick this out.

Sam he is running another 0.2bar boost over you. I tuned car back to 400hub 350lb/ft with the belt slipping. Still good numbers few issues to sort out during the day. And WHO likes the PTFE tape on the JIC unions IT IS NOT NEEDED the connectors seal on the taper on the ends not the THREADS :teeth: :teeth:

Main issue we have seen is that the top of the block is open deck. Top of sleeves aren't supported. But I agree running liners is a pain as they sometimes move after fitment. we have motors running 600bhp with no liners without any issue. If your going to run liners use Darton closed deck liners , just get a new block shipped to Darton in the US get them to fit the liners and get it shipped to you. That's what we ran in project Zed , liners where never the issue we just used to pull the top out of the blocks but we was running nearly triple the power you want to run. Just fit a HR motor will run 550bhp stock.

Base map good?

Far far too young to be taken from this world. RIP Mark. Our thoughts go out for his family and friends

Could be detonation, are you running 95 or 98 octane fuel?

Did Jez reload a stock MAP into the ECU prior to trying the car again on the MOT emission test? I very much doubt the MOT emission test machine will be out of calibration. The rear lambda's don't need syncing to the ECU, just bolt them in and they are all okay normally.

Gary, have you got the emission sheet? can you scan it and post it up on here? after you drove the car t warm the cats was the car tested quickly or did you have to wait before having the emission test?

All the track-day people will have instructors. Well worth the cost.

Awesome place done many a lap @ Spa, both in a Fun Cup beetle in the 25 hour race and in a pretty trick Nissan 32GTR; This is a short video from last year in the wet Get an instructor for 30 mins it will help and if it wet stay off the racing line normally very slippery on the racing line in the wet. we are going twice this year hopefully the 2nd time with our 350Z track car.

Stock Vortech system in my eyes isnt very good; The extra pump in the fuel line just boost the fuel pressure to an un-controlled pressure as there isn't a pressure reg after the in line fuel pump; The stock dead end fuel system run the fuel pressure regulator in the fuel tank. The split fire system is a piggy back system and the 350Z ECU doesn't like having the input/output signals adjusted. And as Sam says if the boost ID pipe to the piggy back controller splits or is blocked instant engine melt down ( a lot of engine use this idea of measuring boost pressure for map sensors/boost controllers without any issues thou so Sam is just being super safe) So when the 2nd fuel pump is triggered it increases the fuel pressure too the injectors to increase fuelling. What we advise people to do with existing fitted Vortech SC kits or kits we fit when we do an install. fuel return system and uprated fuel pump in the tank UPREV uprated AFM larger sized injectors Uprev license and remap allows the ECU to work like stock with full closed loop fueling and knock control up to 5000rpm like a stock car. If you car isn't a UK DE you can even have multi maps switched by the cruise control switch. We have the tune sorted now the car drive like a stock car including cold/hot starting.
