I got a Walbro FRB 11 from here , working well, long life and low power consumption.
I'm curious, where did you mount it?
PM on its way.

The Black Widow is alive :twisted:
Just fired her up, lift pump did the trick. 8 psi at 32 gph. Still need to get my clutch deal figured out, fab up the charge piping and downpipe, and wire the gauges. Mounted the intercooler this morning, after dinner now I will go fab the charge pipes and hopefully the downpipe as well before 1 am, than in the morning do the gauges and pull the end cone of the tranny and see whats up. Hopefully get it on the street tomorrow and see how she rips.
LOVE the sound of the franken motor.

Nice job! I was just looking at your clutch pressure plate, the picture where it shows the welded strap, I was just wondering if it is the bolt head
on the underside of the strap that is just hitting the cast part.
Once the flywheel is bolted on, it is being compressed and won't have enough clearance to let the friction plate release.
Just a thought,
Have a great Christmas and a happy new year.

Herman, I cut off the bolt heads and ends after they were all welded up, which isn't shown in that picture. I just pulled the cap off the 5th gear end cone, the throwout bearing is sitting way too far down in there, the push rod finger is fine. So something is wrong with my pressure plate, not sure what, I've done this before without ill effect. :?

Hi Dave, in the exitement to get it running could you have forgotten to put the pushrod in or the little push plate?
Happened to me once replacing the clutch, had the car jacked up and the push plate and spring ended up under the front tire, never saw it.:oops:
Sure a pain to have to pull it back out

No the pushrod and push plate are both in there, I pulled the rod out, looks fine, throwout bearing is brand new and in good shape. Something about the the push plates position is wack, with the end cap off I can get the pushrod to bottom out on the push plate, but its too far down the throwout bearings bore. The pushrod finger is fine and on the correct spline. Tranny has to come out :x I would have pulled it out tonight but because of my recent appendix removal my gut isn't quite ready for the rest of my body to be a tranny jack all by itself, that and I burnt the back of my hand pretty good about 2 hours ago
I'm having all the luck around here :lol:
I'll get the tranny out in the morning and try and solve the problem. I have a wedding to go to tomorrow as well as finish christmas shopping so I don;t have much time, and my sunday is booked as well. All day monday and tuesday though, can't wait to get this thing ripping down the road :twisted:

Oh and I've seen one of my friends do the push plate mistake as well. He was doing it my shop on the hoist, and I was sick as a dog so I was laying on the fab table just makin sure no one was getting hurt, a while after he got the tranny back in I got up to answer a question he had, looked at his parts pile and noticed the push plate... Poor guy had to pull it all apart again.

just coming here in the trailing end of this thread, but have you swapped the pushrod for another? I know this is a long shot, but I know 4sp rods are shorter than 5sp and I have even seen 5sp rods worn to the point that they dont work right. Maybe as simple as a pushrod swap?

Already pulled the pushrod out and compared to another from the same code gearbox. :wink: I don't see how it could be anything else, somethin with the pressure plate center plate is not right. The weird thing is seems like quite a bit, the throwout bearing seems to be about 3/4" too deep in its bore, unfortunately I don't have any other cars here with o2o gearboxes to check to get a more accurate measurement.

Another thought then is the possiblity of a cracked pushrod finger. I just replaced one of those yesterday and another one a week ago. Still trying to save you here
If it makes you feel any better, I get to replace my clutch on the Scirocco tomorrow. I dont know your setup (tl,dr) but I used a new "used" 210mm clutch off the shelf when I put it together and from my experience, Sachs had a bad run of pressure plates/release plates about a year ago. That would date my clutch to that time. For some reason the three retainer fingers were not close enough to the crank to retain the release plate :roll: on top of that, I also saw multiple failures of the release plate ripping one of the three alignment fingers off. Now I dont know if it was one or the other but it seemed that it all happened in the same time span of the new clutches we were doing at the time.
HTH.

Yeah as mentioned above I already checked the clutch pushrod finger. I am wondering if the push plate center has kinda moved out a bit or something... I don't know, but I will in a couple hours as soon as one of my buddys half way recovers from last night and makes it out here to help me.

Ok so tranny is out, clutch is apart, new pressure plate arrived this morning...
Everything measures the same, between my pressure plate and a brand new sachs pressure plate. And this is with the thrust plate, clutch disk and flywheel installed. So its not the pressure plate. I think something is up with the thrust plate itself. I think I am just going to extend the little center rivet of the thrust plate out more and weld it in place... First I'll do some more digging around the shop thrust plates.
