See first post. I never had the car back while the cobra HFCs where fitted Sent from my HTC One M9 using Tapatalk

Tempted to get in on this too. Me and scottdky are coming down but I just to find out if he wants to join the convoy

If my experience with body shops is anything to go by you are a very brave man

I'm with you now. Cheers Sent from my HTC One M9 using Tapatalk

Hey Alex, just realised that -2.5% would be 0.2% difference between front and rear. Would that really work? Or have I miss understood what you mean Sent from my HTC One M9 using Tapatalk

I've used that one before, this is my favourite though tbh http://www.kouki.co.uk/utilities/visual-tyre-size-calculator Sent from my HTC One M9 using Tapatalk

Just a quick one as I've not been able to find a straight answer online. forgetting about alloy size for a moment, am I right in thinking that as long as the rear tyres are a certain % larger than the fronts, traction control will be happy? Does anyone know that the difference threshold is before it gets upset? There is a 2.7% difference between the stock tyres 225/45/18 front and 245/45/18 rear. I know, as I'm currently running, 255/35/19 fr, 275/35/19 rr (2.1% diff.) cause no issues, and I've seen suggestions of running 245/35/19 fr, 275/35/19 rr (3.2% diff.) so assuming that no issue either or even 225/40/18 fr, 245/40/18 rr (2.5% diff.) is also fine for some. So if I change my wheels and tyres to fit 245/40/18 fr, 265/40/18 rr, (2.4% diff.) I assume TC will still be happy? So if anyone knows, what is the threshold? 2.7% dfference -/+ 1%?

Only standard stuff. HKS Panel Filter, Plenum Spacer, Milltek Cat Back and a RevUp

Well the car has its MOT but has gone back to stock cats. Also had a P2 while it was with Japex. Thinking of selling my LMGT4's after Japshow to fund a nice set of Work T7R's in Matt gunmetal. What do you reckon?

Posted - have added that on. Thanks for telling me, it was in the first draft I promise

Cobra and Berk HFC's for DE engine - £275 each pair posted Please note that the reason for sale is that my car will not pass an MOT emissions test with either of the HFC's fitted. The Cobras HAVE passed MOT's on the previous owners car but would not go through while on mine so I have switched back to stock cats. Cobra HFC's - SOLD Berk HFC's - SOLD Berk HFC's were purchased new from Tarmac in late 2013, fitted to the car in April/May 2014, and have been removed this month. The Berks were wrapped in the hope that they might retain enough heat to bring the numbers down however since seeing the report, this isn't going to work. Will be sold wrapped but its easy enough to remove.They have not been back on the car since being wrapped so the wrap will smoke slightly after fitting. Also to note that the Berks come with O2 sensor spacers hence the longer O2 ports.

Right well having seen the numbers looks like back to stock cats it is... Neither the Berks or the second hand Cobra HFCs are anything like close to passing :\

Not been an update on this for a while! Currently my car is with Japex having its P2 service and an MOT. I've been having trouble with emissions with the Berk HFCs so I brought a pair of cobra HFCs second hand but no improvement . Currently I've got Ross putting the stock cats back on to get it through the MOT but I would like to keep running the Berks if possible. They are very very close to passing and both I and Mark at Abbey think it's down to the cats not being hot enough. I've got some exhaust wrap so as the Berks are off I'm going to wrap them and hope that keeps them just hot enough to pass. Anyone else done this? Would be good to know if my thinking works or is at least accurate.

Mods this can be closed. Sold elsewhere recently.

Bump - Lights still available

Good to know, cheers Mark

dyno plot of DE (green plot) with Plenum spacer/drop in filter/stock cats and cat back exhaust and tuned with UPREV and our HR cat back exhaust/stock cats /drop in filters and UPREV tune DE is pretty close in midrange torque but once your up in the revs the HR romps away. below is a dyno plot of a DE with headers (not long tube) and HKS step 1 cams and it isn't far away from the HR just is held back RPM wise. I think a DE is a very good track car a lot cheaper to buy than a HR car as well. Reason our car has a HR was the DE was using oil and we needed to do some development ECU wise on the HR motors. So if the motor goes its worth changing up go a HR then otherwise both are pretty close? I seem to remember you saying somewhere that swapping the HR into the DE was a massive pain.

Out of curiosity more than anything, would you say the HR motor is a better base for a track car than the DE or RevUp? I remember you saying the RevUp is kind of the 'ugly duckling' of the three when I came in for my UpRev tune.

Only done the national circuit in my own car but have driven the International when I did my ARDS and on the GTR experiences I've done. I can see the International or GP circuit being a bit dull without a quick car but the National is pretty short with a couple of decent complexes so I enjoy it.
