Thoughts? Cam combos?

[buguy]

Here is what I did to my heads. The intake ports weren't quite finished in that pic, but that's what I already had loaded on the samba. It was close enough to done to see what I did. Keep in mind I did very little research on it, just did what I thought was right. Check out how all of my valves are different! Quality units!

[Schweg]

Yeah. I’m not finding a ton of great cost effective and time effective things. I’m going to have to mull this over for a while.

My other big item I thought of tonight is the spark plugs. My manifolds don’t let me swap them with out pulling them so some moved plug holes would solve that.

I’m he more I think about heads and things I still debate a big bore cause torque is king.

Those ID injectors would hold me for a fair amount if I go with the 1300x they will cover a ton and as far as I can tell still have good idle manners.

Don't think your gonna get 40-50 PSI the heads will 'Lift' unless u add four more head studs

[Schweg]

We will see, that’s what half this is about playing and learning . At 30 psi I’m hitting a decent pressure ratio for sequential operation for the turbos I have.

[madmike]

It's all fun until It starts co$ting you guys are trying to get 'power/torque H.P' whatever you want to call it from a 1600cc mouse by adding boost , that my stroker does this with only 6 -10 lbs and 5000 rpm but it's fun to learn like said

[Schweg]

I’m sure there is a stroker in my future. Just not in the cards for now. A big engine is more expensive then the one that came with the car and turbos I have laying around

[madmike]

took me around 5 years to collect parts for my 2276cc,swap meets, mostly good used parts except bearings ,rings, cam,cylinders I have less then 2k invested

[buguy]

I don't know if I agree with that at all. I bet at 6 psi your 2275 would be lucky to make 170hp. 30 psi on a mouse motor should be around 235 hp. Unfortunately for us, you are probably making close to 200 ft LBS of torque at 2500 rpm! Mouse motor probably would never make that tq ever.

[GARRICK.CLARK1]

schweg, best plugs on a turbo motor are the non projected tip ones, projected tip plugs can promote pinging

[madmike]

Ok 10 lbs.

[buguy]

Still only looking at around 185 hp @ 10 psi from what I've seen. You'd be looking at 16-17 psi to make that same 235 hp of a 30 psi mouse. But that wasn't really the point. Boost is a good equalizer! But it's that big low rpm torque of a stroker that's hard to match. I'd have to figure out how to keep mine at 20+ psi all the time to make it close to even. Which I could do. Just saying there are many ways to skin a cat. And if you think your carbed stroker is good on gas, try an efi mouse motor!
Me... I'll take a big stroker AND big boost please!

[Clonebug]

Most strokers are never dynoed at low rpm.....they always start at 3000 rpm or higher and they aren't that much more torquey than a small engine with close to stock cam and boost coming on at 2200-2400 rpm.
As soon as you cam it for high rpm power your low end suffers. As Smokey Unick said in his book...most cams are only perfect for a 300 rpm area.....which 300 rpm do you pick????

Go compare the dyno graphs in the Engine/combos thread on that other site to a turbo engine that has a well sized turbo for street use.
Any time you increase your intake size to gain power up top you give up power down low.
My big valve heads changed my lower torque values I'm quite sure. I'll bet the bigger intakes have some effect on it too. It's all about trade offs.

The Swede's 1641 makes 400 plus hp but if you don't drive it just right you ain't going anywhere fast and you certainly won't do much on the street at a stop light when you have to put it on the 2 step for 4 seconds to build boost before it will launch.
Popping and banging ain't going to cut it too many times before you are up to your **S in blue lights.

[Schweg]

We have gone well past the initial question but I’m loving this thread. It has a fair amount of information that I’m sure guys newer to VW like me have a lot. Though I know most of these items are all engine specific not just VW.

As for the 400 hp, and torque claims and etc etc.

Everyone has there thing they enjoy / want. They are all trade off items.

I get torn about how to use my time and money effectively. So this thread has helped get me looking at things in a new light. I want stop light to stop light power. So I’m looking to build something awesome 0-100.

Thanks everyone for the responses

[buguy]

It's fun huh?! I wish I could be more help. To be honest I don't know why I even bothered messing with mine. At these big (ish) boost levels I feel like there isn't a car on the road that could outrun me. Not true at all, but the damn thing feels super fast!
You will probably find the same sort of thing I did when I was asking around. Most everyone just laughed at me. You know, you can't run 30 psi on a stock engine right?! It will never hold up! Your really doing some stuff that just has never really been done so the info just isn't out there. There are some guys that have a ton of experience, and can give you their opinions, but they have little to no real knowledge on running a ton of boost on a stock engine.
I personally really feel like stock, or nearly stock engine with MS, intercooling, E85 or meth Injection, and a TD04 is about as good as it's going to be for the street. Maybe a little bump in the cam and some port work on the heads by someone that knows what they are doing might help some. If you saw the turbo map Mario did for me, I'm already pretty far out of range at 28 psi. So more boost for me is just going to create more heat. On that turbo anyway!
I'd love to see what you come up with on the compounds though! With those, you might get away with a little more. Only one way to find out!

[Schweg]

So the compounds get crazier! In that the high pressure turbo gets hyper efficient as the low pressure turbo comes on line. So let’s say you run 15 lbs on the high pressure(small) turbo then as your low pressure (big) turbo spools and starts to force pressurized air in shaft speed drops on the high pressure turbo and this is a super simple explanation but the pressures compound so 15 and 15 on each turbo but also at some point you have to add atmospheric pressure back in.

I’m working on that project but it’s slow for sure. The wife and I just had our second baby girl last week so I’m super slim on sleep and garage time. But I have some good research time being on new born hours.
I’ll be back on it in a few months maybe.
