    Well look at you!

    I have a SV 85B for doing my heads. It'a a were one with variable speed feed drive. The best thing I did was to put a VFD on the spindle. I over clock it at 120hz and it does just fine.

    Yea Max is still arguing the problems with my doors was due to the amount of bodywork on my car. Yet he always goes silent when I post pictures of the holes being in the wrong place for the latch and pictures of the top ledge being too wide to let the door panel fit over it. Really weird situation but based on how successful his business seems to be doing I would say it's the correct business model to have in these modern times. I'm old and have this quaint idea that you should stand behind your product if you want to have a successful business. He's starting to push back on me posting my well documented problems with his doors and his lack of standing behind his product but based on the fact that the doors are unusable  I'm going to get my pound of flesh :)

    Might be a good project for someone that could adapt this to an L6 easily....Derek?

    NO!!!  :)

    Actually it seems well suited to a billet solution and I can't compete with billet solutions. The only reason I can play in this arena with my equipment is leveraging my pattern making abilities.

    I'm in Florida and I use 2 smaller fans in puller config an a single larger fan in front of the condenser in pusher mode that comes on with the AC clutch. Sitting still you really need air passing through that condenser. I have the radiator fans controlled by my Megasquirt.

    Some of their stuff is good and some is hot garbage. Max the owner doesn't stand behind his product and has a tendency to try and blame "modifications" to your car as the reason. I have a lengthly (4 page) post on classic z car about my problems with his door assemblies. 

     

    Resurrected Classics door problems

     

    I have their door weather strips and their fuel filler neck and the are excellent. My advice is no matter what you buy test fit as soon as it arrives and go from there.

     

    The doors were so bad that I ended up not using them. Max refuses to refund my money so I make sure to take the time to tell people about my experience. Do not trust what he says as he says whatever he needs to to get out of doing the right thing.  Caveat Emptor with this guy for sure.

    Forums dying, can they be saved?

    in Non Tech Board

    I've been doing the best I can on FB to try and encourage people the return to the forums to no avail. The general attitude is, and I quote, "too cumbersome".  People would rather have the wrong answer in a hurry than the right answer that takes a little work. There are so many FB groups for the S30 that there is no way to get any kind of quality answers.  I don't know how many times I could of contributed to someones question but didn't because I knew the answer was easily found on one of the three forums.

     

    You are starting to see that AI is burrowing its way into the FB groups as well. Sad times these are.

    All I’ve read in my adventure is that there is no way to run ITBS with speed density correctly

    I agree and I brought that up with him. He had a ton of ITB experience with Megasquirt so I deferred to his expertise. The only complaint I have is when I'm low speed lugging through my neighborhood it really starts lugging. Other than that it runs great as far as I'm concerned. I tend to have my foot in it most of the time though. DOHC and ITBs under load makes for some sweet music :)

    Don't worry PAMS is already testing a real DOHC head on cars and you will actually be able to buy it. I expect prices to be better and unlike this head it will install without a headache and an engineering team.

    I have two heads in stock as I type this so the head can actually be purchased. I can't help that you can't afford it.

    That's a feature not a bug. For the very beginning my goal was to provide the components so that talented engine builders could make the decisions on the types of components they wanted to use.

    Based on what I've seen and taking the pricing of the relatively simple L6 head as the baseline I highly doubt it.

     

    I'm not really sure what I did to put a burr under your saddle but you remind me of the guy that starts a fight in the line to get into the club because he can't afford the cover charge.  Just get out of line and go somewhere else.

    Are you running the ITB or Alpha N ? 

    My tuner has me setup with speed density and a separate idle table. All in all it does fine but the reality is until I build my stroker I have way too much induction for the displacement.

    I’m so tired of the FB shit 

    I commented on a post about scammer groups and said that if we were still on forums there would be better control of this. Since there are 9 bazillion S30 groups it hardly got seen and the one comment was "forums are too cumbersome" 

     

    I go there because that's where the customers are but I'll be dammed if I'm going to answer stuff that I know for a fact has been documented in detail on one of the three forums.  The answer to every question I see should be "google it" :)

    Poly tank from Vintage Tank Solutions install discussion.

    Are you still having fuel tank backpressure issues? 

    On the stock tank? Yes. I haven't started the poly tank install yet. I'm convinced Nissan added the vent on the left side of the tank to deal with the situation. There is no other reason for it to be there. You have to be in just the right climate and usage for it to be a problem. Cool morning fill up, and then parked in the sun all day. There is a real potential to form a vapor bubble there and it expands at a greater rate than liquid. Since I have that plugged the vapors path to release is to force all of the gas that is in the upper section of the tank out if it can. A proper check valve system in the vent line to atmosphere would probably solve it but I'm not crazy about having a pressurized tank.

     

    I've just finished testing some polyurethane tubing submerged in gasoline for a few weeks with no sign of degradation. I have a plan to use that as an in-tank vent line. I'll post pictures when I finish it. I also ordered a Tanks Inc. 6" backing ring and I'm going to machine my own custom top plate to provide the inlets and outlets I want.
