JohnSyn Posted May 16, 2020 Report Share Posted May 16, 2020 I'm a bit confused, which realistically isn't difficult! There appears to be two very different and firmly held views as to this upgrade; its not worth doing or it really is worth doing! Has anyone undertaken this and have they felt it made a difference?

map Posted May 16, 2020 Report Share Posted May 16, 2020 @JohnSyn you know where I stand on his from a 986 perspective - genuinely interested to see what responses you get from those who’ve actually applied it to a 981. Link to comment Share on other sites More sharing options...

Hi Matthew Yes and it really helpful to chat through with you to get some understanding of the journey, although mine if I do it won’t be as extensive as what you have done!

daz05 Posted May 16, 2020 Report Share Posted May 16, 2020 I'm keen to understand this too, I think the best bang for buck is a tune. Link to comment Share on other sites More sharing options...

I’m sure you are right, in terms of bhp etc. Very little difference. I think the mods are more about increasing the responsiveness of the car, that is sharper throttle response etc. Link to comment Share on other sites More sharing options...

daz05 Posted May 16, 2020 Report Share Posted May 16, 2020 I'd like a slightly sweeter top end, and more mid range like the 3.6 in the 997.2. Link to comment Share on other sites More sharing options...
daz05 Posted May 16, 2020 Report Share Posted May 16, 2020 This is probably where my money would go. Ehresmann in Germany. https://m.facebook.com/story.php?story_fbid=511341752400375&id=325484277652791 Link to comment Share on other sites More sharing options...
edc Posted May 16, 2020 Report Share Posted May 16, 2020 @Mark Shead can do the Cobb for you. Who was the German guy who came to Blackbushe with the Ehresmann modded 981? I would look at the Ehresmann website as he shows a lot of dynos and results for the 981. Link to comment Share on other sites More sharing options...

I agree the Ehresmann mods look interesting, particularly the larger engine conversions. Patt has mentioned @Mark Shead and it is something that I'd consider if I go down the improvement route.

mneil Posted May 16, 2020 Report Share Posted May 16, 2020 Having equal length headers with 200 cell sports cats fitted this Wednesday. Had the car mapped at AET Motorsport couple of years back and that put a smile on face , +10%extra torque very noticeable. Have got Tony Banks exhaust Leeds, lined up to make me a custom cat back system later. Link to comment Share on other sites More sharing options...

Mark is highly regarded in the Cosworth tuning field and would have been in my top two go to guys back in the day,never used him tho as my buddy was the other guy lol.Mapping is an art and hes also a Porsche enthusiast..

I think the mods are more about increasing the responsiveness of the car, that is sharper throttle response etc. I suspect it’s this. People are talking about how many extra horses; with these cars I don’t see that as the discussion, it is more about where the horses appear through the power band and how that improves real world drivability. When was the last few times anyone set a 0-60 time? Stronger 40-60 or 20-50 far more useful on a daily basis. Link to comment Share on other sites More sharing options...
Patt Posted May 18, 2020 Report Share Posted May 18, 2020 I've also seen a few Youtube videos on the dyno with zero gains for the IPD (although no tune added) I have heard it improves the induction sound, but that's an expensive gain that could probably be emulated by removing sound deadening material. I have used Mark in my Evo days and will always recommend him. The beauty of the Cobb is you can chose which map you want, ie turn it back to normal if required. Also you can get a bespoke "pro tune" done if you so wish. The annoying part is no-one knows how to put the PDK into "dyno mode" like they do for every other car.

mneil Posted May 20, 2020 Report Share Posted May 20, 2020 Had the new headers with the 200 cell sports cats fitted today. Posted in the"what have you done to your 981 today" With hindsight, it feels as if the new headers etc has enhanced the previous remap, whatever the reason the car had certainly come alive!

I read your post on the other thread, its interesting you feel the new headers have enhanced the remap. Logic would suggest the other way round, headers then remap, should work very well but it looks like its the same the other way! Link to comment Share on other sites More sharing options...

The changed map and headers are essentially sub-systems of a larger machine - improvements to one area will produce gains, improve a second, connected area and you often see gains where "the whole is greater than the sum of the parts". It maybe that a further tweak of the map now would yield additional improvements. Regardless it's great to see folk modifying their cars to their own taste 👍 Link to comment Share on other sites More sharing options...
