I use those on my beetle. Comments above on damping based on a stock weight shell.

So the have different valving...

Guess they´ll be good then?

That the code for the rear set I have. I imagine the front damper will have lower damping than the rear. Although in my experience (on a stock shell) the front damper is ideal at the lowest setting (firmer than stock).

I’m not expert on suspension but it you have the original torsion spring pack & a lower mass, the suspension frequency will be higher. That is the same effect as having a stronger spring on a stock weight body. So perhaps (in theory) the damping needs to be higher to manage the higher suspension frequency?

GT6-2302 are the fronts
GT6-2303 are the rears.

So as I understand it they will re-valve the fronts ti compensate for my lower weight, as they say it´s a 4 week deliverytime to make them

Yes, mine took a month from order to shipping as they are made to order

yeah nice ride I had one 15 years ago..

[rubenski]

Yeah it´s a big project. I estimate 1 to 2 years to get it going.

My girlfriend and I bought it together.







It´s 90% empty now, making it ready for some welding. Front window area, driver floor, battery plate and rear beam under engine lid.

Chassis is like new.

But i´ll better make a topic in the bus forums.

Went dragracing about 2 weeks ago.

After the dyno not much was done to the buggy. It just ran like a champ.
Removed the passenger seat and front window.

Got tagged for 10sec.
Did 5 runs, first run again a 12.7 like last time.

Next run a 12.24 wich is now my PB.

Could not get it faster, unless i make more mods.

That would have to be: heavier torsion springs, different gearbox ratio´s, solid engine & gearbox mounts.

But since this is a street car with maybe 1 drag event/year it will stay as it is beacause I would have to sacrifice street comfort.

I know the engine will get this car in the 11´s but not with how the chassis is now and the mods needed as I said above.

On my last run I had a perfect start an wheelie, tried to powershift into 2nd but could´nt... probbl because the box tilted making it impossible to get it into 2nd.

Overall, this 1641cc turbo buggy performed perfect, not a single error or break.
I can measure with drag-spec built 2L-2.5L NA cars. Some wich broke down after 2 runs.
So maybe i´m lucky, or maybe this is just a well built relaiable street-drag-fun-car.

Btw, managed to have a photographer shoot my buggy and get into a UK magazine. More on that soon.

My friend took alot of photo´s on the strip. But the pictures are to large to upload here...

Congrats! Clustres seams to be fun. What's your best 60ft so far. There is another solution to go easy way faster without making it less streetable. But like you said it's a cool working concept.
There will be another Race Event in crastres soon right?

Enlighten me please!

I see my picture of timeslipp is not readable in my photo, is this better?

Hard to ready. 1,7x s? Os that your best 60ft.

Simple as i told you when your Turbine housing cracked. Switch over to holset he221w 7cm. As you can See in your recent and old dyno graphs the more in boost steals your rpm . With that tiny holset it will come back and even more rpm usable as in your low boost graphs. And you will have +2,5bar usable boost and about 100hp more without loosing Low end. Just the turbo and the Pipe from your Header ( would change the whole Pipe, yours have way too much Volume , steals efficency and spool time)
Your Car will have more rpm in every Gear with the Same Setup, your top Speed will rise and you have 1 bar more boost to use. I can send you Pictures of logfiles when i used it on my 1584cc.
Earlier boost than in your build and about twice as much under the Graph even with tiny less boost than in your setup. Hard to compare both engines but it's a very fast spooling cheap turbo that is in quality unbeatable and a torquemonster and is moste Happy in the 1,5-2,2 bar range.
It's btw a td04hl size to compare with your turbo.

1.736.

But i have 4 more timeslips, I´ll compare them when i´m home.

Yeah i agree with you on the turbo and pipe work.

Maybe if my current turbo grenades....
