THE worst day ever since I started racing..........
Failed the noise test going out to qualify, fitted a baffle to one side and all clear to go. 8/15
Decided to take the baffle out as restricting the car, queuing up in assembly and the scrutineer is upset we took the baffle out, if we put it back you can race.
Just as we were going onto track he stops us and says you have nothing on the other side " your not racing"
I tried to explain how quiet the car is on track compared to all the throttle bodied cars, not interested as it must be 105db static......
We make a baffle for the other side from a can with loads of holes, he measures the noise and 100db so we can race . Wait the 3 hours for the next race.
Started last and got to 4th on 1st lap, car was flying then she gave up as struggling to breathe through the tiny exhaust baffles.
Compression test tonight and 1 and 4 cylinders 70 and 90 psi.

Sorry to hear that Dave, hope it gets sorted soon mate.
How did the baffles bugger up the engine? :bw:

Try running up the road Steve breathing through a straw and see how far you get

Jeez, that sucks ball man. What a downer. I remember trailering the Fuego to Silverstone and only made one warm up lap because of (what turned out to be) stretched wheel nuts! Its a kick in the teeth alright, but you just gotta suck it up and pick yourself back up

Pretty sure as it couldn't breathe properly.
Will be taking engine out soon and taking a look,

As stated on FB Dave - R&D all the way fella. You've got the right attitude, and your car is more than up to it. Get sorted - move on.
It's really great to see the results you have got on the RR, I was wondering how you got on, but having read above, it's all good.
Keep it up buddy, you have a lot of support and keen followers out here.

Restricting gas flow wouldnt kill an engine....running lean would, but this would be in issue with the inlet NOT exhaust side
I disagree with that. If the gasses cannot escape as efficiently , even with the aid of the turbo then the engine will have to work harder to compress what it cannot get rid of therefore increasing the cylinder pressures

Why would this lead to a loss of compression? Not being able to get rid of the gasses would simply 'choke' the engine and effectively stall the turbo...only possibilty would be an increase in temps which could potentially melt a piston.
Best thing to do....remove your head and have a look at your piston crowns and bores. Could be a failed headgasket due to overheating if its run hot

I disagree with you disagreeing, I think you would see cracked liners and head gaskets going before rings start dissolving, Blown rings is usually too hot in my books, if you bung up the exhaust, the turbo won't work efficiently therefore not making as much power. Cars with too smaller exhaust don't blow engines, they just become asthmatic.
Ha , laughed at the disagree with disagree
I think the increased temps will have caused the ring , or possibly even liner distortion due to the thermal stress.
I disagree with everyone because I'm busy running up the road with a straw in my mouth..
