Quick update My new mid exhaust box turned up yesterday, going to fit it soon and see if it still quieten's it down enough, this one is 4" in diameter, the first one i bought was 6" in diameter but is touching the floor, it's not nice to drive like that the replacement IMG_20200528_101105 by Ian Austin, on Flickr IMG_20200528_101128 by Ian Austin, on Flickr
Sure this one won't need the alteration, might have to alter the other one even more if this one is to loud
you seen my system ian...thats a 3",and has a center box about the same diameter as the one you have on it now.This was designed to be under 90db for racetracks...so maybe this skinny pipe might be a little on the small side.
mines 3" dump, no cats full mandrel 3" system jus back box . ktec i believe 87db at cadwell lovely and quiet too
I have to be there for 15.30, but i will be there early, need to get it done asap as i have a six hour drive home, i will aim t be there for 14.30 the latest.
Hi Guys A bit of an update My exhaust not banging against the floor anymore Its a lot better to drive on the road now, not sure if it is louder of=r not as the 6" box was making such a noise rattling against the bottom, its definitely quieter inside.
I visited a forum member on Saturday, trying to find out why his car was smoking and making a strange noise when hot. Good steady drive up to Shaftesbury, carried out some work, then we went off to collect me some tyres . Then on the drive home it sounded like the exhaust was blowing, well it sounded like a spark plug was on its way out, it didn't seem to get any worse so kept going, i also knew i had a slight oil leak on the back of the engine somewhere. as this has this big turbo fitted, there is very little chance it can be removed with the engine in the car, so once again the engine has to come out. IMG_20200615_161409 by Ian Austin, on Flickr Started to look around and all the nuts that were holding the turbo on had come loose, a bit strange as i used some wedge ramp washers, anyway so i removed the turbo and this is whats left of the gasket.

you,ll need fire nuts on that flange ian,there specifically for extreme heat. tighten as they get hotter
Ian, in my experience, that kind of gasket are shit, it cost to me a track day. Since that, I ever use metallic or multi-lamin gaskets for the exhaust system. Cheer up master!
Ha ha ha i'm good, i have two weeks to go till remapping, so i have nothing to do very much on the car so whet the hell pull it out I have now fitted a thin metal gasket I also had an oil leak and couldn't see where it was coming from, plus i had a really good look around everything to see if there were any pipes rubbing etc, all looks great. Would have got it all back together today but i'm waiting for a oil temperature sender to arrive, fitting it with the radiator in is neigh on impossible
The ones on the flange i made haven't shifted, its the ones holding the Borg Warner on, there M10's with Nord lock washers and they still came loose
Looking forward to it for sure, i have done a good few miles now and it all seems good. It feels quite quick now, it definitely needs tuning, the mid range is a bit flat, but once it goes over that all hell breaks out In preparation i have done an oil and filter change, new plugs and coils, new tyres all round, new CL8 pads, caliper seal kit, also replaced the two track control arms today. So all should be good to go
Silverstone on the 15th of December and then i did one on the 17th at Oulton Park they were the last ones
Not the figure we were thinking of, there seems to be a problem with the actuator that came with the turbo, going to have to get another maybe something like the Turbosmart one, hope it's not an engine out job again this is the final two runs you can see the fluctuation and the boost falling off due to the actuator problem. More to come by Ian Austin, on Flickr
That was the one i was told NOT to get as they are also unreliable Drive home was very interesting, so easy to get into 3 figures without even trying, still about 50hp short by all accounts
Hi Guys A bit of an update I ordered a Turbosmart actuator last weekend and it arrived during the week, it looks a good bit of kit well it should be for what it cost IMG_20200709_192805 by Ian Austin, on Flickr
i tried to fit it where the other one was but as its larger in diameter it wasn't going to happen. So after a lot of trying different locations, the best option was found, so on Friday i started to make a bracket, finished it off Saturday. IMG_20200711_133707 by Ian Austin, on Flickr
