Mythbuster: continuing project thread of my 1303 '75

[evilC]

Maybe it's that your in a different space/time continuem? Personally, I go with Einstein that as you approach the speed of light you get longer. If you get longer it stands to reason that it will take lomnger to get round

[Humble]

I'll take your bug for a spin after you and we could compare telemetry I just need to get over there... Ideally though, that's the best way to measure improvements accurately, to use a telemetry box and compare overlays with other drivers.

That´s alright Wally...don´t push it! Speed comes with confidence.Like TSAF said,you´ve made a lot of changes and you´ve invested a lot of time and money in that project.It´s a hobby and it´s built to have fun.As long as you´re having fun and constantly improving,who cares what the other drivers are running.

Well said

Thanks for the encouragement guys!

The rear wing is ugly from the sides, but I already knew I need to make nicer stands or buy something:

I've just lost all respect for Wally's accomplishments now ... is that a BBQ sitting just over your intercooler ?

Just Kidding ... you kick ass as usual, glad to see you finally got a prize

Congrats.

Wally I will agree with you that the wing is extremely ugly. Have you ever thought to start your own turbocharged type iv engine shop? Well you should because after this reading this thread again I honestly believe that you have more experience on turbocharged type iv engines than anybody else. Seriously give a little thought to this idea!!!!!!!!!!!!!!!!!!!!!!!!!!!. You have built an extremely powerful engine and you have "test" it on "real" circumstances. By that I mean the tracks. You are not just words like most builders. Think about that and forget about the track times.

Thanks mate! I do know what works and what helps by now and I help in writing some articles for a (dutch) magazine and maybe a rebuild and/or tuning book might appear sometime from that same mag, but I will definitely not build engines for others. I really encourage others to build their own blocks as I think that is/should be part of the fun (hence the writing ).

And yeah, I need to make or buy something more fancy as a rear wing ;-)

Of course there were again a few people that asked if there was a subaru engine in there...I told one of them to come close so I could smack him!

Hi Wally

Did the picnic table have any effect on the intercooler?

Yeah, yeah, yeah, I know, Iknow

But no, it doesn't as I did deliberately positioned the wing so the gap was big enough that the air following the roof line flows uninterrupted towards the intercooler.
It IS functional in that respect. Any roof lips or other roof spoilers however WILL effect intercooler efficiency imo.





Wrt 'looks' of the rear wing: its also depending on the angle how you look at it I think:

The wing doesn't bother me. Form follows function, until optimum function is figured out...then yes, make it look good ;-)

Yeah,stab ém with a chop stick Awesome pics Wally! Are these photographers scheduled at these events? Or do they just randomly take the pics and you download them from a website or sth? As professional as they are,I would guess that they are hired by the event organizer? Keep ém coming Wally! They keep me motivated!! A big thanks for that!

Its a pretty big event in our little country, so lots of photographers are interested, either hired by publishers or independant ones where you can buy your pics for a reasonable (debatable, I know) fee. I was offered to share a pit box with one of the publishing parties. But rest assured, they took plenty pics of all cars present :

I know Clive, don't worry
Bruce: I really wouldn't want any bigger. I also think it makes the whole construction less stable if its wider then this. As Rob experienced, if the wing gives too much down force, the metal under the rear wing can give in (and probably gives more drag also), so too much wing is not wanted either I feel.

The center pod on the wing is already my own addition, which I found necessary (even when the wing was in its original low position, that was needed to make it stable) as well as the extra diagonal rod to the intercooler top.
As it is now, its very stable and I don't see it move or shake at all at any speed or surface conditions. Better stands and stronger material (steel plate instead of the alu now) should make it able to do without the extra horizontal/diagonal rod (I hope).
Maybe sometime next year

Thanks for the nice comments guys!

ha ha, nope doesn't look good from any angle.
However the car still looks fantastic and more importantly, totally under control on the track.

You might want to consider a much wider wing, that extends to over the rear wheel arches and out from behind the main cabin. This would get it right into the air flow and increase the effect a fair amount.
