Time to go stage 3

Mapping started last Friday at Devil with Romain from RaceCal.
First couple of hours were spend do checks and generally setting up the Syvecs before starting runs. Managed to get up to 634 on low boost and no additional timing but it started getting a bit heat soaked.
The plan is still to get the best power on fuel only and run the WMI as a back up only on the high maps, still using the 3D controller.

I’m booked back in for August as nd currently running a very safe 300hp map. The stage 4 DSG map goes in this week and I’ve decided to swap out the Forge intercooler. It was great even in the heat up to 600hp but then the temp rose too quickly. Shame as it’s only been on the car for 3000 miles, but I’m sure someone will be happy with it at a reduced price. The Eventuri RS3 that did 211mph was running a one off CFS intercooler and luckily Regal have got them to agree to make us another one. Eventuri tried other ICs which weren’t good enough and settled on this one. One issue is it’s too big to have a crash bar but I guess the answer is don’t crash lol.

In the meantime I’m happily driving around with 600hp and drivability as good as oem without even getting the DSG map yet. Plenty more to come but no rush.

Do you have a vid of you launching it? Everytime I launch mine its bonkers and that's on a standard car. Yours must be insane.

When I was stage 2+ with about 530hp it was brutal but as yet I’ve not launched with 600hp. I waiting till it’s all finished and the TVS stage 4 DSG map is done. This will be bespoke to match the final logs and should make it safer. Also I didn’t have a Wavetrack or the subframe & suspension before.

I spoke to someone with a Golf R who ended up stuffing his engine due to a WMI failure. 100% made up my mind I will not run a WMI dependent map for more power. Whatever I get to on a reasonable boost lvl will be it and the WMI will be there as a back up only for cooling with no additional timing added. This build is for more power but I’m also doing everything possible to make it more reliable.

The CFS intercooler will be getting shipped next week so when it arrives I will take photos of it next to the oem and Forge ones.

CFS intercooler on route. First picture I have when completed. I am looking forward to comparing to the OEM and Forge ones and will post the pictures with measurements.

Shiny, shiny. Looks very much like the ones they use in the states from IROZ and RACE3. Should work really well.

Probably a similar size because I know the IROZ 1000hp core is also too big to have a crash bar. Really interested to size it against the oem and Forge ones.

The iroz 1000 core, race 3 core and stm core all work with the Audi USDM  Crash Bar (8V5-807-109-D)as it has a little extra clearance compared to the UK variant. The US bar can be purchased for TPS with above part number and costs around £200-250, If you go above 3.8" thickness on the core then you need a skinny bar which is offered by race 3. SRM which uses a CSF core rated to 1000bhp also fits with the US bar. Left a few links below

Thanks for the information. I think the one I’m getting is the CFS core with the SRM tanks, but as yet not sure if it is exactly the same core or not. The only thing I know is it’s the exact same core as the prototype one used on the Eventuri RS3. Either way it’s going to be at least 1000hp rated and better than the Forge one I have currently.

It has arrived but I’m not able to see it for 2 weeks due to work. Being fitted on the 5th ready for driving to Eddy Brooke Racing on the 8th.

1000hp IC in after a new bracket being made to raise the oil cooler up. The SRM end tanks are way bigger and better shaped than the Forge ones, so should help keep the IATs down.



Hopefully I will be collecting my car from EBR tomorrow after fitting the inconel exhaust system. I can’t wait to hear what it sounds like because I’ve not found any done previously on the internet.

Nice progress!

When’s D Day for the mapping? I bet you can’t wait.

Mapping nearly completed. Runs 650 at 2 bar which was my target as I want reliability. Stage 4 gearbox map done and works really well. With all the suspension and chassis work it really shifts. I will be going back to have the E85 map and will go a bit higher on the boost. Also the 2 bar map (map 4) will have WMI but it couldn’t be done this time because it needed to be wired in directly to the Syvecs.

Exhaust is really good but way too loud for the street. Louder than any RS3 I’ve ever heard and it’s setting off my neighbours car alarms, so BRE are making new silencers for the rear which hopefully will be fitted in the next couple of weeks.

Now I’ve done a couple of rolling road days I’m going to get another oil change soon. Getting there.

Now your fully mapped @ 2bar & with a stage 4 gearbox map to boot it be nice to see some draggy times before it's remapped for WMI especially with all the weight saving you've done.

Do you have any Dyno graphs/print outs of your latest remapping.

Got to ask and no this isn't a dig, just genuinely interested.

Who advised an intercooler that supports 1000hp but running 650hp? Your cooler will be way to big and create pressure drop, secondly ali end caps with an intercooler that isn't coated will be a heat pump on its own. Black deflects radiation, heat is radiation.

I noticed you was at 635hp on low boost but now 625hp@2bar which doesn't add up.

Are you running a SRM turbo ?

Believe it is a TTE855

It was just over 1.9 bar. I will be going back in November for some further mapping once I get the exhaust back boxes sorted and will be running race fuel map.
Yes it’s a TTE855 turbo. To be honest I think on race fuel it will run more than the TTE777 could but not convinced on pump without WMI. On pump it’s still a hybrid turbo which produces more heat than a full frame. Yes you can cool with WMI or run race fuel but mainly it will be a street car.

Ben - yes I hear you on the intercooler colour and something I will sort at some point. I’d like to see some test done on the same ICs in black and metal. The old IC was getting heat soaked at the 650 point but perfect at 600 so probably perfect for stage 2+. I now have a surplus Forge IC and crash bar that only did 2k miles. Doesn’t seem any laggier but hard to say because I’d not driven it much with the 855 after initial map. Feels similar to the 777 with main boost in at 3800 rpm.

I know Buchrs fitted an IMS 650 which could be better but I’ve never seen maps showing the power curves apart from the US which always show higher. Would be nice to see if a UK pump car is or is not laggy on that set up because they have a better manifold design than the oem.

The one thing about running Syvecs is it’s more cautious than the oem ecu in regards to when it thinks something is potentially on the edge. I saw a Golf R that was tuned with and without Syvecs and on oem it was tuned right to the edge before anything flagged where the Syvecs had safer limits by what I’m guessing is better prediction and quicker response.
It’s a work in progress and I will be doing more weight saving for sure. Front seats, battery and brakes are in the list for early next year and I’d like to swap the rear subframe late this year for the lighter drag version.

That makes no sense, promoters are set by tuner. Sensors being used are oem. Ecu stock or aftermarket is only an input and output. I can tell you now syvecs has nothing on stock ecu. Syvecs is used to make tuning easy for tuners with less experience with stock management. Once you patch in a ram logger to stock ecu logging data is unreal. My experience syvecs is a waste of money on the FL and doesn't have any gains over stock ecu.

Hi Ben

 

Where syvecs is ahead is that it allows you to add additional sensors like EGT, coolant pressure and such a lot easier than the oem ecu but you're correct it is easier to tune than the oem ecu for someone less experienced on this platform. The logger for the DS1 is just as good if not better than the Syvecs.
