Mythbuster: continuing project thread of my 1303 '75

[kuleinc]

I know you never said it was a DD, I just wanted clarification on how driveable it is, off the track, seems its very much so...

[Wally]

Ah, yes, its remarkably drivable: I can drive in 3rd gear 1100-1200 rpm and power on without hesitation.
That's a bit of EFI tuning as well though I must confess

[kuleinc]

I'm STILL getting together all my EFI bits, and I can't wait to get that kind of driveabillity, my dual kads are the suck... but they were always a stop gap solution until I got the EFI together...

I SO badly want to open the case up do some oil mods, and make the engine bigger...

You're car has always been one of my favorites!

[petevw]

Sweet, 350hp.

LOVE IT.... I'm with daddy
if you want a bigger one then you should put a Coil and a Spark plug in the tailpipe and hook it up you would get a HUGE flame lol

Love all your reactions!

Found a vid of a very fast dutch street-legal dragracer with an Opel Speedster, which I ran 'against' earlier this year. He runs with slicks in unlimited class. I am in a A/Street/Legal which require road legal threaded tires.

In the run of this vid got a little too much smoke from the burn-out....opened the roof, but 'your not allowed to run with open roof'... I know dude, but can't you see the smoke thats blinding me? Maybe thats not safe to run with either huh?
He had to laugh about it then as well fortunately

nice
im sure u said some where already. but what tires are u running they seem to hook up well

[Xellex]

Wally, excuse me for asking, but do you by any chance, have a spare trigger wheel like the one that you are using? Or maybe can have one more of those made? I'll pay for it
Oh, and nice vids, btw!

Its a semi-slick street/trackday tire in 245/35/18 size: Bridgestone SP Super Sport race, threadwear 60 (!), I really like them but they don't make those anymore.

Xellex: sorry, can't help you there..

Something to handle the upgraded power a bit better (I hope) through the corners: 944 M030 25.5mm torsion bars:

[MX67]

Wally, nice job!

I hope those 25.5s will be OK, because I also bought them for my project. I guess, I'm waiting for the update about how they changed Your Bug, meaning driving feeling!

Regarding Your performance, those numbers looks serious. I believe most of us trust Your opinion on turbocharged Type 4 engine subject (I do, because I don't know anybody else who made engine "from schratch" with totaly simple parts, plus modern tehnology like FI and Turbo to get serious numbers). I'm wondering only one thing:

Considering Your today's knowledge, experience and abilities, how much Your engine costs? Roughly. Is it 3000 euros, 5000 euros, or what? I really trust You on this one, because I was thinking about STI (sorry people) because it costs me 2500 euros, has 300 HP and 350+ Nm.

Thank You!

Best regards from chap who said hello on Spa Franchorchamps at Le bug show

2500 euros won´t get you far on an aircooled motor.Depending on what you can do yourself and how good your existing parts are and if you have a complete motor,you may be able to build a longblock without the fan assembly and throttlebodies for that.Fan and throttlebodies can cost up to 1600 Euros alone, a proper engine Management like DTA or KMS will run you another 1000 euros without the wire bundle.Megasquirt is another option and will be a bit cheaper.Proper headwork is pricey if you don´t have the means to do it yourself.Then you have the turbo,wastegate,bov,intercooler,hoses,fittings,etc .it adds up quickly...

This is the reason why I'm asking Wally to elaborate his engine. Because of price, I'm on the STI side, even if it is not old school. But Wally has some interesting cheap solutions that work well...
