2276 build

I believe you could make more. Although I'd be plenty happy with that. I seem to remember that article but I thought it was on cast Mahle cylinders.

[Schweg]

Can’t find the article but found a samba thread it was 360hp at 28 psi. Which on a four barrel draw through is super impressive.

I’m still sold on a 2L+ as a large draw of a 2L+ build is not having to run 20+ lbs to get equal performance to what we have now. But also knowing that if / when you go high boost that it’s going to haul!

[Chip Birks]

Yeah I have the same dilemma. I need brakes too. I go back and fourth on the heads for the 1915. Buy cheap ones to throw on, or buy the ones I want for the stroker. I'm just worried I'd be bummed to build a nice big shiny stroker only to put used heads on it.
And yes. I just couldn't bring myself to buy a CW 69mm crank when they are the same price as an 82 mm.
I guess I won't know how I feel about the 1915 compared to a stroker until I actually have a stroker. I have a feeling I will like it just fine. As long as I get a little of that low end back. Also hope I can turn a few more revs than the 1600. Seems to fall off around 5700 or so now. I'd like to turn it more like 6500.

Just remember, they are only new the first time you bolt them on

Schweg, when I was building my last VW engine (a long time ago) I talked to several different VW engine machinists and, at the time, it was thought that boring the case to accommodate the 1915 cylinders was iffy, especially with certain (year?) engine blocks, which is one of the reasons why I stopped at a 1776. This allowed me room to go to an 1835 (assuming I didn't mess up the block during using it) if I needed to... at some later date (so far I have not needed to for how I use it also based on how I built the engine).

Stroking also has advantages unless your crank is bouncing off the road from too long of a stroke.

I was brought up, in the car neighborhood, that you did it right the first time then live with it but since then things have changed so much in the last few year... and are still changing that it is hard to know what you will need... later on in the day .

94s are extremely common place now.

[buguy]

It would probably be smart to run thick wall 92mm, especially running big boost. But I never claimed to be smart.

I can't even imagine running big boost on a big 2L+. Mine feels stupid enough at high boost now. Going to be scary for sure.
The off boost performance is really what will be super nice. Although I don't recall ever having any trouble keeping up with traffic the way it is

[Ol'fogasaurus]

As I said, it was the engine case itself that was the biggest problem according to them. I think it may have been a '68 (H+something) but not positive.

Correction: it was the 94 cylinders that were the problem (87s and 88s while they work are not recommended either) I also understand, after doing some looking around that there is/was a 93 that may be better.

We aren't dealing with the super thin walls 88s of the 80s anymore. They have retooled and made them crazy thick. The 92s of that era were bad too. But again, there is a thick wall replacement now. 94s are a little thin, but again, many many in service working just fine. People also used to say you couldn't reliably drive a stroker on the street, or that you can't run more than 8psi of boost on pump gas, or that 200hp NA with pump gas is impossible. All of this stuff is happening now. That's the beauty of adding a little technology into the mix.
It's fun proving people wrong.

[Schweg]

Lee- I think that there is knowledge to get from prior guys and what worked. But also agree with Chip in that a little technology goes a long way.

Which leads to a bunch unknowns for guys looking for information. I can find 100 threads about how you have to run H-beam rods. But you look for hp numbers or a dyno run to back things up and there isn’t a lot. It’s frustrating.

[madmike]

The reason for the H-beam is for clearance also not just strength, check them new I -beams ,Jaycee's make a $trong one too,lol
never would I use a stock rod that been 'clearanced' , seen a few 'vetelated' cases from that

The cylinder walls of the 94s isn't what I was talking about as much as it was the machining of the VW engine block so they could be installed... things were getting thin there was what I had been told about. That is why I mentioned the blocks from a certain year.

Most of the rest I pretty much agree with as electronics have made some of that more possible. I had never heard the "stroker" problem before as strokers' have long been built and just not in ACVWs. More grunt but the RPM limitations part has of some concern by some.

Lying from ersatz engine builders or part makers are still a problem from what I understand. I bought an engine from one of my late stepsons friends that when it failed, almost immediately, and torn back down... nothing was there that the guy had paid big bucks for.

I agree that the H-beams are for strength, clearance, and they are lightweight. 94's are a bit of a concern for me, but sometimes you just have to roll the dice. But as was said, they also said you can't boost stock p&c much either, and stock rocker shafts will break, and you can't boost to 30 psi on stock studs... Etc... Etc..
Every single person I called when I was looking to buy a part (Tims, CB, trans shops) all laughed at me when I told them what I was doing and wanted to do. I heard a lot of "I hope you plan to.." and "You can't do that..." Who's laughing now?!
It will be a year in July since my first start on this set up, and no catastrophes yet. In fact, I think I will go get it now and take it for a rip!

[Ol'fogasaurus]

Laughing at others is not couth! If one has an opinion about something or an idea about doing something it is OK to state but the response back should be in a civil manner. New, fresh ideas are good and even better if proved correct. Seen a lot of "wrong" by repliers in my life time.

As I try to say most of the time: "my opinion is worth slightly less than you paid for it." It's supposed to come up with my signature but never has so I have to do it... when I remember.

Lee

[buguy]

Sure. And maybe it's silly what I'm doing.... But then again... Maybe it's not! I mean I certainly didn't reinvent the wheel here. I think it was the stock parts that got everyone.
