While waiting for JK's super vids, here's a vid from Greeceland.

This is from our track weekend. Unfortunately we were never in the track at the same time, it would have been very interesting IF I also had my 1.8T there instead of the 24v 3liter... 8) Maybe next year.

OK, so were you in the 1:33s then?

Apparently this 33 1.7 16V (modded I presume) did it in 132.9!!

Which begs the question, where are your vids?

Power aside, the V6 @ 7800 rpm is a hell of a lot more nicer than 7000 rpm on a 1.8T. All turbos sound almost alike that you just lose interest in them. Not denying the power though...

The 33 driver is very good! The car has ~165whp and slick tires.
My time with the 1.8T was 1.36 with 888's and Bilsteins -next year it will be full RSR like the 24v. Slicks are worth 2.5-3" in this track and this puts the cars miles apart. To analyze/appreciate times, you must compare what each car has in terms of tire size, weight, hp, torque etc. My 1.8T is 1.3" faster than the 24v. Let's see why:
1.8T / 24v
275hp / 272hp
400Nm / 380Nm
1210kg / 1180kg
1.8T gearbox / TS gearbox
205/50-15 888 / 225/45-15 888
306mm discs small 4-pots / 306mm discs big 4-pots
The main difference is torque and the calipers. A I said elsewhere, the big series Brembos have much better deceleration than the small series, enabling later braking. I also noticed better cornering with the fatter tires in spite of V6 understeer.
For next year, I plan :roll: to have the new 1.8T engine, hoping for ~330hp and ~420-430Nm torque. Combine this with slicks, or Dunlop CR311 tires -highly acclaimed here by many- I should be looking at much better lap times. Car weight will not change (its a road car after all) but from what I saw comparing the 24v vs 1.8T, the slingshot acceleration out of corners from the snail, is unmatched by na motors.
I don't have a car camera, maybe I can get one by next year or borrow on for the track. I would like a Gopro with the suction cup mount and the rear monitor pack but hey, these things all cost money you know... :|

I would say yes, probably having to do with the relatively high weight of the 75. Note also that the 205/50-15's are on 7" Compomotives and the 225/45-15's are on 8" ones, same offset, camber, etc. Of course there still is understeer (the kind you can't correct with applying power) but I can only (reasonably?) assume the better balanced 1.8T will do much better around corners with the 225/45-15's.

Thanks.... I have been considering moving from 205 to 225, which would mean going from 7" wheel to 8" wheel.... was Not sure if the difference in performance would be worth the cost and hassle.... my car weighs ~1050Kg at moment but I am running a full RS kit

You can only gain with wider rubber, given the higher percentage of contact patch.

I'm now on Nitto NT01 235/40/17 on 17 x 8 ET30. Cheaper and it more than matches the R888s. I used to have Hoosier slicks 225/45/17 but they don't last and I hate it when they give way, they give way in a big uncontrollable way. Besides slicks have lower life spans, and after 2-3 weekends, they are done. So that's my justification for no longer running slicks.

Now I'm looking for 17 x 9 ET 20 Enkei RPF1 when I get the 3.2 done and make the 17 X 8 my practice tire and fit some 235/40/17 Toyo R1Rs on them.

JK,

I bught a Sony Action Cam AS10 for $50. Should have nought the AS15 the guy wanted to sell me for $50 and send it to you. Cheap as heck. Seriously, if you want it, let's work out a deal on future parts you can send me. If I find a good deal on it, I can get one for you. You don't need any fancy shamcy stuff. Hell if you can get one of those SJ4000 China cameras it would be good, it's one of th better ones out there.

888's are almost at the bottom of the semis performance rating but they are the only ones available in Greeceland. I would love a set of Toyo RR or Hankook Z214 but they are not approved for sale in Europe (!). Must be some agreements between tire makers. I even called Tirerack and they said they are not allowed to ship these types to Europe! I am therefore limited to what I can get locally or from the rest of Europe -hence the Dunlop CR311, as Pirelli/Michelin slicks cost a fortune. Hankook F200 slicks are also available from Germany/France, does anyone have any experience with these?
For the camera, I prefer to find a good used Gopro set as several guys are happy with them here.
