Activa 0-60

The finnish Citroën club arranged it's yearly track day couple of weeks ago, and we did some "drag racing" at the start/finish straight of Kemora race track. There was no official timing, it was just for fun... but I had Dynolicious running, and got 0-100km/h down to 7.63 seconds.

I ran twice against a tuned TCT Activa, and it was quite even. After the event the TCT was put to a dyno, and came out with 204hp/263Nm, giving max power just when rpm limiter kicked in.

You can see us going at it starting from 1:29 on this vid:

And yes, there's something wrong with this TCT Activa's roll correction...

Do you know how much tuning was applied to the TCT? The big intercooler is obvious and must make a big difference on its own. You can also hear the gearing on the TCT is a bit shorter than the V6.

Both cars sound very good, i love a turbo burble, on par with a singing V6 imo....

I can hear a Wheelspin quite bad in one of the sprints, sounds like it needs a bit more traction or a longer first gear, have read somewhere on here that the gearbox and clutchs are different from V6's to TCT's though.. maybe the box from a 2.1td would suit the user better?

Don't fancy fitting an IC that big to my xantia myself, loses the Q car sleeper-ness then

Maybe som CO2 over the std IC would do the same trick

Wheelspin is a problem for sure, for both cars. AFAIK both TCT and V6 have the same gearbox with same gearing. Afterwards we found out that I was just shifting at a bit higher rpm.

The TCT has a Mitsubishi TD04HL-15G turbo, 663cc Siemens injectors and 3" exhaust with cat removed (yeah, it sounds pretty good

). It's still limited to <1bar by the ECU, but from what I hear that is about to change soon... he's aiming for ~250hp.

The huge intercooler is quite visible now, but the bumper that is being made for it covers it quite nicely IMO. Here's the project thread at the finnish forum with some pics and videos:

Hehe, guess I'll need to report here aswell

That tuned TCT is mine actually. Here's a list of mods done to the engine:

TD04HL-15G turbo (good for 280hp in 2.3l Volvo 850T5R)
600x300x76mm intercooler
663cc Siemens Deka injectors
VEMS ECU (DP-Engineering "plug'n'play")
3" downpipe continuing with 2,5" pipe with one silencer, without catalysator
Raid HP freeflow airfilter
Pate Racing dump-valve

Haven't dynoed it with Vems, but it has lot's of more power now than when we raced with Koukku

Still needs lots of work..

Few pics:

and here's a link for a quite crappy acceleration video..

Nice, and shows what can be done with a bit of effort. For me, i didnt want to take away the originality too much and reckon i just about struck the right balance.

Managed to get mine in the mid 7's 0-60's, and quicker than a BMW 325ci, which is fast enough for an otherwise standard road car with great roadholding and 5 seats

I had a little race against e46 328 BMW, he had no chance, and it was with stock ecu, fuel cut ruined all the fun!

That new air intake setup looks quite good and i bet it helps bring down the spoolup time as well

Got me thinking now that would make my life easier relocating the air filter to there and just needs a silicone pipe that would fit the job.... hmmm

looking good though, cant wait to see what it does when you have some super sticky track tyres on the front wheels as well
