Finally got the video uploaded of the last few laps of the very last race of this season for #77. Full story is in the Racing forum, but it was an extremely close, well-contested finish, very exciting! Here's the direct link to the video, file size is 32Mb.

EXCELENT RACING !

This is nobody throwing these words but.... i feel that your 924 is a WAY MORE advanced and fast vehicle than that BMW....and if you only would dare more and push the other driver a bit more to be able to close his way after you've past him...he would never catch you...Maby what i'm saying is not legal...or just pure crap...but...i had to say it

good luck in future events and please keep us up to date with your great racing and videos !

I felt that his line was off for a few of the corners, and I do yes feel that if Vaughan did get infront of him that he would gain time on him, and possibly produce slightly faster lap times.

Can't check out the footage yet (crumby unix work computers...), but I'm curious just how the bimmer stacks up. If he's pushing 143hp, then you're definitely at a huge power disadvantage (maybe he's heavy?). If all things are relatively equal besides suspension, them I'm curious what the bimmer has under it in design that gives him an edge?

ps - I read your recount of the day and sounds like great racing! Nothing like having great competition. If you won by seconds all the time, it would be boring

Thanks all!

The Bimmer is a '76 (IIRC) 320i with a 1.8L engine - but yes, they're very similar on paper and to watch on the track. Vastly different to drive, as you can see in my summary (see my Fun Run post in Racing) and can get an idea of in the video.

With our current setups, his car is far superior in corner entry - my car just pushes (understeers), which is why you see me back off going into every corner. But I've got more torque, and can put the power down far better when he's just sliding around at the apex, which allows me to get all those big runs on him.

I wish it were a matter of pushing harder, but we were both pushing as hard as our cars and tires allowed. That said, just because you're behind someone doesn't mean you're slower: I turned a faster lap than he did during that race, by 0.40 seconds, in spite of chasing him. You are correct, Morghen, in that if I'd gotten by him, I once again would have been able to pull away (as I did during the preceding race). However with all of that traffic, there is again the possibility that I might've gotten caught up at some point and again at jeapoardy of losing the spot (as I did in the previous race).

We both have 5-speed trannys, but I've the one with the 4-wheel disc brakes, not him, and it shows - though on a track like this, it doesn't matter. His pedal feel is crap, but the cars are on equal footing here.

Not sure what his weight is, but my car's at about 2650, and I do have the torque/acceleration advantage as noted, not just in a straight line but especially out of corners.

So his advantage here is only in corner entry speed; mine is in corner exit. We'll both be doing some tuning over the winter, I'm sure, to try and level the field...

Nice racing !

Whos on your bonnet ?

It was fun to se the difference in racing line. Of course he had to take a more defensive line but it looked like the biggest difference in speed came from you choosing a better line. And acceleration out of the turns like tou said..

What are you planning to do about the not so sharp turn in?. have tried a 931 with racing suspension, and the turn in was super sharp. A very well balanced and stiff car. Lots of the racier front motored porsches i´ve came in touch with do have that kind of really sharp turn in. seems strange that your doesnt. What spring setup do you have ?

There are a coulple of e21´s racing over here. I´ve heard that they do tend to have som not so wanted handling abilites sometimes. What i have heard its much "thanks" to the rear end. And a friend of mine if mine who used to race an e30 said that those cars felt a bit of front heavy, even the ones with the fours..Maybe its the same on the e21, i dont know..

What track was that ? Looked fun but not very wide. Even compared to our swedish tracks..=)

Thumbs up for your racing, and videos !!

It's definitely a 320, then, as it's got dual headlights. I'll have another video of him behind me, will show that.

I guarantee the Bimmers were hobbled for the US market just the same as any other Euro cars. And yes, he chose to run a 1.8. Thought the lighter weight would help him. How much you wanna bet he's reconsidering that this winter!!!

Here's another look at his car:

On the bonnet - Jim Hawkins, a fellow ITB racer who passed away last year from lung cancer:

Track is Waterford Hills, near Detroit MI, and my home track:

There's a few things I can do to improve grip up front; I have some 550# springs I may well try (current spring setting is 660#) that should help. Not sure where the balance needs to be, though. It's really on a knife-edge now, we're that close to where the car needs to be.

Sorry to hear about Jim...

seems like a nice track. Not so many boring straights

It would be intressting to know wich tires you have, does everybode need to have the same ?

I think he runs on 700# springs up front, with 911turbo torsion bars..Works nice. What do you have at the rear. Maybe stiffening it up a bit ? instead of softening the front.

Khal, m8

if you read carefully i wrote:

"...i feel that your 924 is a WAY MORE advanced and fast vehicle than that BMW..."

this means that i felt that HIS 924 is faster than THAT bmw....not that the 924 is better than the bmw...wich i dont know if it is or not...it may have 4 disk braking but is just CRAP...as you know...and everybody knows that bmws never had performant brakes(you can even see that in the video...the bmw is always early on the brakes..) compared to the 924 drums that are usable even in races ! but...i dont care about that...

All i'm saying is that the bmw is holding him down and he could produce faster laps without the bmw infront of him...

on a later edit:

The BMWs that Khal is speaking about are not faster..nor more advanced than our euro 924s...i personaly know a guy that owns a BMW produced in 198x wich is a 2.0L and has 125 HP...so when you are quoted 125 HP for older 2.0L bmws..they are probably right... the 1983 2.3i models had 148 BHP and 205 Nm of torqe and had the weight of the 924...they were faster on 0-100kmph but on the 1000m the 924 would cach up...not to mention about the weight distribution....

LOL... brakes don't matter at this track, it's too short, we don't go fast enough. Do you know I don't even have cooling ducts on my brakes???

We don't need to all run the same tires, but all the fast guys do: Hoosier road race radials, R6's this season. He's on 14's, I'm on 225/45/15s. But it all ends up working out about the same, we all have the same grip level, and therefore the same cornering and braking potential.

I can't make the rear any stiffer, I've already got 36mm hollow torsion bars! Though a more adjustable rear swaybar would be nice, springs are cheaper and I prefer them.
