Thought I`d share this video from last week.
Enjoy. :smiley:

Brilliant time. I was down to around 8.45 in my S3, but was at a pace that I was relieved it was all over.
What is the spec of your mark 2?

2.0 ABF engine, DIY GSXR 750 Throttle bodies with Megasquirt 1 V3 ECU. Was on the rollers a couple of weeks ago and gave 149HP at the hubs.
02a Gearbox, with Quaife LSD. 288mm Brakes, SPAX RSX suspension, standard front ARB, no rear one.
Car has been built and tweaked over the last 4 years and I`m really pleased with how it is going now. I stopped timing after that lap, there are a few corners where I carry more speed on some laps, but overall, thats easily the quickest lap I`ve recorded. Did an 8.28 and 8.26 the day before, both those were with passenger too.
I`ve done about 1,200 laps of the ring, that definately helps :grin:

how much ?! jesus what do you do?

That has been done over the last 6 years and many ring trips :wink:

The legend that is Nige Pinder.
The car is epic, the build thread is epic and the driving always seems to be bob-on, too. :grin:
All I need to do it make up another 30 seconds per lap and I'll be all over you like a rash - how hard can it be? :shocked:

a post , a build and person that DH likes - miracles do happen :laugh: :grin:

Not only that, it was all said in one post! :shocked: :grin:

I know Nige and his work from another forum I frequent.
Bloke's got skills.
-
Good power from those mods. That will be circa 185 at the flywheel will it not. That time though is still fantastic. I was expecting a much more exotic car to be honest.
For people who have not been thatis time will not mean much. For people who have....wow!!

Just watched lap again. Your car does not seem that fast if the speedo is accurate. I got to 140 on the stretch before the right hander that drops into foxholes. Yours looked like 110ish. You must have some awesome lines, because you are not doing those times with power. Big respect :smiley:
-
hello Nige impressive lap that, good to meet you over there at the weekend thanks for the suggestions were to try for parts etc i'm one of the Andy's with the broken silver mk4 ,we managed to get a coil pack tuesday afternoon and some laps in tuesday evening ,i'll be over to northloop to say hello and thanks in the week all the best andy
-
8pot, my speedo is almost spot on. VMax is 126 on the way downhill towards Schwedencreuz and 125 in the foxhole. I manage the heady heights of 105 going up kesselchen :grin:
Its all about momentum and being smooth for me, as you say, I don`t have the power to make up time on the straights.
Andy, really pleased to hear you got the coilpack sorted and managed to get some laps in before coming home !
-
any chance of a link to the cars build thread? Always a treat to flick through someones hard labour!

Yeah, here you go, a cup of coffee and a spare hour or 2 may be handy :grin:. http://www.northloop.co.uk/forum/showthread.php?4332-Nigels-2nd-Golf-MK2-Trackcar. (http://www.northloop.co.uk/forum/showthread.php?4332-Nigels-2nd-Golf-MK2-Trackcar.)
The latest Aero improvements had made a noticeable difference. :smiley:
Here is a `chase` lap from my mates M3 following me from my trip the other week.

had a quick read through the aero bits you put on, good to see it all works! if you are running a tall block you can use a short block manifold to your advantage to tuck the exhaust up into the tunnel if you ever wanted to go lower and raise the floor a bit. but i suppose the fuel tank would be in the way then!
-
Didn`t know about the short block manifold. Good info.
However, if I raised the floor, it would mean raising the splitter and (within reason), the lower that is to the ground, the better, so raising the floor would be counter productive :wink:
The diffuser is as close as possible to the fuel tank already too.
-
next step has to be fuel cell i'm thinking and brig it inside the car or under where the rear bench once was.
allows the back of the car to be chopped about a bit more as well as bringing weight in between the wheels
-
the next step after that is sprung loaded skirts, ground effect baby :laugh:
-
DH linked me to your project thread the other day and in all honesty I thought you were taking the piss out of someone or was a wind up with the aero stuff but glad it does work for you.
loving the chat between your mate and his kid :grin: "whats that smell?" :grin:

I would remove it if it didn`t work :wink:
I`m not blazing a trail here, the theory and application is well proven, the difference is, a lot of race series have limits on ground clearance / silhouette etc, so they can`t do as much as I do, but it genuinely DOES work. I need to get a photo of it on track, the amount of spray the diffuser sucks up is amazing !
Fuel cell is more effort than its worth TBH. As I said earlier, there is no benefit to raising the flat floor height.

Northloop is worth the log in.

Joined northloop just to read the thread, well worth it imo :cool:
Funny I had been pondering what difference if any a flat floor would make to my mk2. A fair bit it would seem, but I'm a long way off doing anything that drastic.
Good video, as for how fast you would have gone without passenger I recall a conversation with a drag racer who advised that 10kg = 0.1sec approx. So for every 10kg you remove you shave a tenth off your quarter mile time. So say your passenger weighs 90kgs that equals .9 sec each quarter mile, which would equate very roughly to +3.6sec per mile. So if the 'ring is 3.2(?) miles long that would make you around 11.52sec slower over a lap with a passenger. So without a passenger would have brought your time down to 8min09sec (ish).
Given that I have no idea how much your passenger weighs but the maths is simple enough.

Sorry but your level of understanding is somewhat off here :embarassed:. The 1/4 mile guy would have been on about losing time during pure acceleration from rest, the ring is not all full bore acceleration from zero speed. Its also rather longer than 3.2 miles so assuming your maths is correct and assuming approximately 13 miles (dont know the precise B2G length) he would be about 45 seconds faster a lap which I think even the OP would agree is stretching things a touch lol :grin:.
-
IIRC the yardstick is that you'll be about 10 seconds faster without a passenger.
Always much more fun to have a victim though. :grin:
-
I wish it was 45 seconds ! :grin:
Some say its worth 10 seconds per lap. Honestly ? I dunno. I can tell the car is accelerating quicker with no passenger, I need to change gear before certain corners, where with a passenger, I don`t.
However, the car is also a bit more stable with a passenger, so its a trade off really.
-
:grin: Aye, fair point. I hadn't considered it wasn't pure acceleration, but that may have more to do with my driving style than anything else.
Epic time none the less, and have to say Nige what a build thread!
And I thought I was committed. Nasty things those exhaust valves when they get loose in you engine and I truly felt for you when that nut disappeared at the 'ring too. Still, kudos for getting stuck in about it, no point in bleating about it just get it fixed, man after my own heart :cool: :cool:
-
Cracking car and cracking lap... Great Video to watch. Not very often have I seen the ring that clear!
-

Yeah, the nut was a pain, but it was my mistake that caused it.
The valve, well, that was just a PITA. :angry: I`m just pleased I took it for a test drive, otherwise it would have happened at knockhill. Imagine, driving all that way then it blowing up on the first few laps ! :shocked: At least I had time (just) to fix it when it went.

Yup that would have been an absolute 'mare, and they do seem to get a bit shirty when pistons get spat out on their nice clean track.
Fortunately though, you seem to be a bit of spanner twirling ninja. :smiley:
-
I read your build thread, that mk2 is a bit of a beast, and its no suprise about the time round the ring. Got some driving skills
-
amazing stuff just read through some of your build thread, top work Nige and what an effort at the ring for that time! fair play :smiley:
