Time attack beetle

[volkdent]

Oh NO Will!!!! Oh that just SUCKS. I was hoping to hear glowing stories, not that it blew. You know, water isn't as bad as you might think...(said the snake from the tree)

Thanks so much for coming up, sorry that the logger wasn't working, I'm going to call them today and see if I can get to the bottom of it. I did work on the intake boot, turns out it was being squashed by it's position, so I cut it and am trying a new angle that I hope will work. It's all sort of in a holding pattern till the gt28rs goes in, but some air will probably make it work better. I doubt it will help too much with cold running, I'll just have to keep plugging on that.

That's a rather cheap shot...

...and yes it IS bad in a beetle .

Really sorry to hear that humble, I was hoping to make it out to BLTN and see your car...

Where and when do they meet anyways? I work in Fremont, and always see a lot of VW's on random Thursdays on my way home from work LOL

Heh, I was using water (injection) and it helped quite a bit but it wasn't enough.

I got video and pictures up today, and the video will be a good carrot on a stick to get the motor back together. The dyno was at Blacktrax and Jei is the man trying to work his dyno majic but Lucy didn't want to play along.

Why can't I hear any devastating engine noises?

Man that just sux. Always hate to hear this kind of stuff.

Keep the chin up.

Any chance your cam timing is off a tooth? That would kinda explain the 5k rev range, and possibly the kaboom? It just doesn't sound like the timing is right to me, like it's retarded.

I do agree that it sounds very wrong to begin with. Just doesn't run smooth, but kinda like its on 3 cylinders or something. Timing way off could also sound like that maybe.

Maybe flat cam?

Turbo does spool nicely on a positive note.

The cam timing was spot on 0* not advanced or retarded. The motor did start winding up up to 7500 on the dyno after some tuning. In the video he was tuning 2000-5500 pulls and loading up different amounts of boost so he wasn't takingit to redline.

He did have the timing advanced quite a bit looking at the maps, up to 50* of advance, which tells me the mechanical timing is off quite a bit. When he was tuning he was pushing for max torque by adjusting the timing but 50*of advance is unreal. But even so, since it's electronic the timing would work out correctly at the crank (or so i'm thinking).

The only things I can think of for possibly causing such extremely low numbers are flat cam or possibly the manifolds. I remembered last night I never swapped the manifolds for the correctly ported ones, so the intake manifolds on the car have stock sized ports where they meet the head. Do you think that flow restriction alone would limit to 120hp?

Looks like I'll be able to get the car home today or tomorrow and tear the motor out on sunday possibly. Hopefully by sunday night, or midway through next week we'll know the failure points.
