Leon Cupra R25

[POPOV]

How did U put those seats in place? Driver and passenger Sparco seats. Did you use custom made rails or something else? I want proper seat also!

I made my own adapters, no adjustment options at all. The driver seat has been set to fit my driving position only and passenger seat has been moved as far back as possible to fit tal people.

One of my best investments I must say, nothing beats the feeling of being able to really sense how the car is acting on the road.

Performance

During the last couple of days I've been pushing the car too see how fast it really is. I'm really struggling with grip at speeds below 100km/h, first and second gear are thereby an challenge.
In forth gear I can get away without spinning my tires, that's the downside of FWD. This is for sure still a really fun car, especially in higher speeds.

So far I've manged to do 100-200 in 7.37s, VBOX verified.
Conditions:

• 10C ambient temp
• 19" 235/35
• not using NLS
• 98 RON
• WMI on
• 1340Kg
• Manual shift

With better tire traction and a NLS I'm sure I would get below 7.0s .
In the graph attached the green g-force graph line shows my shift .

Mate,its a one fun piece of car thar u made.i agree,that all that horses and torque is hard to handle in lower speed..
700nm is truck torque not car

Again,its a beast on road!respect

VBOX corrected time

It seems as there are many ways of measuring VBOX times. This is what I learned.
The different methods show a big difference in time results, I present the results from the same 100-200 run.

Visual time 7.4s
Visual check of what the display is showing.
Good but not accurate as it doesn't take altitude changes into account
See first Image attached below

Verified time 7.37s
Extract the .DBN file from your VBOX and upload it to: http://vboxverify.com/
This will only accept times with ~2% altitude difference, if larger delta they will be classed invalid
See second Image attached below

Corrected time 7.28s
This is where it get's interesting, if your driving down a large slope your times will always be magic. This method takes the altitude differences of the run into account and corrects it accordingly.
As you can see in the blue graph my run was performed on an increasing altitude.
See second Image attached below

By using the DB Scanner tool the altitude changes are taken into account. In my case that was positive for the end results
See third Image attached bellow


Sure, these margins are smal but in a hobby where 5 hp makes a difference this is as applicable . Yes, it doesn't take wind into account

As always, thank you for the credit =)

There are actually several other 2.5 TFSI engine swaps that inspired me to do this build.

And the one Scirocco RS Quattro building in Russia for my daily use

Love your project Alex!

Photo session

I've enjoyed the R25 the last couple of weeks but as temperature is creeping down due to winter closing up the front wheels are fighting for grip.
The R25 will be put into hibernation soon to spare it from salted roads and bad weather.

I reached out to a car magazine some time ago and they showed interest in my car. I meet up with one of their very cool photographer one day.
This fellow was really passionate about his job, enthusiastic people are rare nowadays. He want beyond expectations during the photo session and even used his personal car in creative ways.

Phase II

It's time to move on and initiate phase II of the Cupra R25 project, all wheel drive!

Several parts need to be sourced before I can get the AWD conversion started.

• Haldex coupling, generation 4
• Rear axle, AWD version
• Fuel tank, AWD version
• Prop shaft
• Rear drive shafts
• Bolts and miscellaneous parts

I've been eager to purchase an Haldex coupling from a trusted Polish seller and could no longer withstand the need. If purchased locally I would have to pay 1500€, I payed including shipping from Poland 330€!
As my ECU is from a TTRS I sourced a gen 4 Haldex coupling, it "should" be plug and play.

Downside of going AWD is the drive-train loss and increased weight due to the heavy Haldex coupling, it weights 36 Kg according to my weight scale. What more can I delete now to compensate for this .
I guess this second phase of the project will be finalized in the end of spring. I should be able to do some more 100-200 VBOX tests before the AWD goes on.
I'll use the results as a guideline of where I want to be after converting to AWD, maybe a Phase III of this project is needed

During the black Friday sale I purchased a full set of Black Powerflex bushings for the rear AWD axle. It should keep the car stiff and improve the road performance.

Nice project. AWD will give the car a much diferent handling.

U should gone awd from start od build.but i still love the build u did.have great respect to people who do engine swap,that in very uncommon!!!!

Thanks !
Due to the complexity (out of my perspective, one man show) of the project, time frame and budget I planned for the AWD to come as a second phase. Now the second phase has been initiated .

Subscribed.............looking forward to the progress.

Rear AWD axle

Moving on with the AWD conversion, slowly gathering the parts needed to complete the conversion.
Manged to source a complete rear axle with the aluminum subframe and hubs, there's a steel subframe and hub version to.

As you might know by now I'm addicted to lowering the overall weight of the car, the AWD conversion unfortunately adds more then 80Kg .

How its going?winter is slowly comming to an end :-D

Hey pal, slowly collecting parts for the AWD conversion, I'll share more soon. I doubt weather will be good enough for another month.

Front-cover featured

Another dream of mine has become reality as my car made it to the front cover of the magazine I wrote about in an earlier post on here.
To see the image of your car in the stores magazine section is really something!

AWD part sourcing

I have now manged to source all the parts for the AWD conversion.
Plan is to have it all fitted and complete the conversion by April month!

For once I don't have any images to share of the last bits I sourced but I've listed them below.

• Fuel tank, AWD version
• Prop shaft
• Rear drive shafts
• Bolts and miscellaneous parts

Amazing build. Congratz on the magazine cover..!
