Being previous Porsche owners it was a great opportunity to use the membership for once and take the R35 GTR out to the Porsche Owners Club of SA Sprint Series Round 1 and test our new updates to the car. It was a punishing 36 degree day here today, so the heat was on, but the new E85 tune, wing and suspension helped us win the day overall in our GTR with the our new PB (1:13.58) being the fastest of any car by around 4 seconds per lap, and there was some fair competition, numerous GT3/911/GT2/Cup style Sports Cars etc. :)

This is the grid for 'Group 1' which is the 'fast class', with the cars lined up in qualifying order. We put the GTR on pole, and then posted fastest time of the day, so we are happy. Here is the GTR jumping off the line and into the lead :cool:

There is still plenty of development left to get another second or so out of this car, but the trap speeds are now impressive being up 10km/h at the 'kink' for a validated 221km/h speed trap figure. The only thing holding us back was a set of tyres that already had a session under their belt.....we wont make this mistake again. Great test for the car, easy win for GTR where it counts :happy:

Great result Martin !

"new PB (1:13.58) being the fastest of any car by around 4 seconds per lap" with "tyres that already had a session under their belt" is an awesome result.

Awesome :) The Aeromotions wing looks great on the car and the "downforce when you need it, low drag when you don't" effect of the wing will definitely be having a positive effect on trap speeds.

What was your previous personal best lap time before this event ?

Posting such high trap speeds on a 36 degree C day is extremely impressive.

awesome top work Martin and Willall Racing

Thanks....and yes we were running E85 today :cool:

Engine temperatures were around 5 -7c cooler than on conventional gasoline, its like having a big radiator. In fact even at the 13 pace we never logged over 98C in 36 deg ambient, which was pretty cool :happy:

The amount of downforce it generated did bend the factory aluminium bootlid though - so we have to work on a 'fix' for that :happy:

Yep the Aeromotions wing generates a lot of downforce :cool:

This thread ... http://www.nagtroc.org/forums/index.php?sh...st&p=478182 ... has a photo and some info on a modification that Aeromotions did to a carbon bootlid and that post reads ...

"... sent it to the wing guys so they could do a couple mods as you can see down the middle of the interior side of the trunk they reinforced it for high downforce loads that the wing will generate."

There is a photo here ...

Are you looking to keep the factory alumnium bootlid or are you going to fit a carbon bootlid long term ?

sounds like a great result Martin, well done. A bit odd the wing bent the stocker boot lid, hmm. I wonder why aeromotions havent figured this would happen- given the apparent testing?

can you give us some feedback on the wing, did you get any data and do you have any conclusions on that?

Hey Martin, Roger, (next to you on the grid), mustve been off his game if you were 4 seconds quicker... Hes usually in the low 16s. Was he really going that slow today? :happy:

Nasty conditions out there today, like an oven

I believe his best was 16.9 in the GT3, vs 13.5 for the GTR, so 3.4 seconds. Mainly it looked to be in the 17s from the lap scoring :P

All the more impressive time Martin! 12s will be a walk in the park on a good day....

wouldnt a wing be more affective if it was attached to a more solid bit of the car. like having some stands underneath the boot lid so the force is pushing down on the floor and not on the boot lid? i dunno im just guessing here?

otherwise that is very immpressive results that im sure will make a few porsche owners red in the face.

We have answered that question at the link below, as we don't want to clog up Martin's thread about his car with info about the Aeromotions Dynamic Wing ...

http://www.tunersgroup.com/Aeromotions_mounting.html

There is already a thread about the Aeromotions Wings on SAU, so please post any questions specifically about the Aeromotions Wing in that thread which you can find here ...

Thats a fair effort Martin,

I cannot help but think that the whole combo is now a good thing and that your trans enhancements are making a substancial contribution to the result!

221 @ the kink is the fastest speed I have ever heard of for a streeter with doors . . . or am I behind the times on this point!

Are you planning to venture accross the borders to WA & NSW with "Triple R" this year?

      WTB R34 GTR Guard Liners

      By Kinkstaah · Posted

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up

      You have a knack for photography my friend. It makes the 86 look like a complete bucket. The 34 went with you to Europe and back. It's special. (we all feel the same about our 'shitboxes' that every bystander seems to absolutely love)
