i have installed the cam setup suprf1y sold me,200-335 intake 210 340 exhaust ... i don't know if its the cams, or the gear ratio that i have installed, but now i have some wheelspin when i floor it in third gear!!! :lol: 8)

great midrange power, great match with td05h 14b or small 16g mitsu turbos!!!

1.3/1.6 16V SOHC
340/200
355/204
365/210

you reccomended the 340/200 (i assume) to me in PM. thoughts on the 355/204 in my setup?



you say these are the stock durations. is this for all G16 or truck G16 or ????? i find it hard to believe the esteem and sidekick G16 use the same cam duration numbers.

1.3 16V SOHC 308L/184D
1.6 16V In 308L/192D Ex308L/198D

according to this the stock G16 cam would be a halfway decent upgrade to a G13.

I looked for that PM, but couldn't find it. I don't recall what profile I recommended.

Those are the correct lift and duration numbers. for the ones I checked. I did not check a later COP Esteem cam.

Mike the new cams are hauling arse, ran a 14.75@94.5mph on Sat and won my class in the circuit sprints too. :thumbsup:

Somehow I missed this.

That's great news. Thanks for the update.
Same profile I'm using in my own GT

I need a cam for my Turbocharged F8B (fuel injected). Do you have ready made grinds/specs for F8B.

What would be a good lift/duration combo that works well for fuel injected F8B NA cam. I need good idle and needs to rev upto 7K. Its running a MHI TD025 turbo with a log manifold.

How much would it cost? Do you need the core to be shipped to you?

Thanks,

Joe

I have nothing for the F8. We don't have those here. This is a 2V per cylinder motor? You're not going to get smooth idle and power to 7000 RPM.
A pic of the cam, or head with valve cover off would be good so I know what I'm working with.

Post subject:  Re: Cam profiles for all models [3 Tech]

Yes, its a 2V motor. Will try to take a pic of the head without valve cover.
Hope you can come up with some cam spec that will deliver power till 5000-5500 rpm. thanks much.

Hi, I'm going to search a cam for my G13b Gti installed on a Fury Kit car.

Actual engine profile is with a modify ECU and custom exhaust profile...

Without substituting other parts do you think I can have a better response from engine with wich kind of profile?

What will the weight of your kit car be?

Post subject:  Re: Cam profiles for all models [3 Tech]

Now should be around 530/550, but my aim is to be near 490kg

Author:  suprf1y [ Fri Feb 01, 2013 6:31 pm ]
Post subject:  Re: Cam profiles for all models [3 Tech]

210/340.
It will give you a rough idle, and power past 8500 RPM.
If you won't rev that high, then 200/335 intake and 210/340 exhaust profiles are also good for 8000+ RPM

Post subject:  Re: Cam profiles for all models [3 Tech]

The second option has a lower rpm torque peak?? (Sorry for my English not always correct :P )

Author:  suprf1y [ Sat Feb 02, 2013 9:52 am ]
Post subject:  Re: Cam profiles for all models [3 Tech]

Yes. It is less aggressive, and power starts sooner.
These are the profiles I use in my own car.

I have a can that I need help with. Its supposes to be the 192/8° with 340 lift. Its it excellent shape. I wanted to measure it and compare to stock. I have a good pair of mitutoyo calipers. I measured the two first lobes from cam gear for consistency. Now keep in mind the numbers I write are not gross lift and don't include rocker ratios. Simply for comparison.

For a base percentage stock lift is .308 and cam x is supposed to be .340 giving a 10.3% gain on both I & E

Exhaust lobe:
Stock base circle 1.217
Stock lobe lift. 1.413
Stock net lift. 0.196

Cam x base circle 1.147
Cam x lobe lift. 1.377
Cam x net lift. 0.230

Based on net lift there is a 17.3% gain. :huh:

Intake lobe:
Stock base circle 1.217
Stock lobe lift. 1.423
Stock net lift. 0.206

Cam x base circle 1.180
Cam x lobe lift. 1.383
Cam x net lift. 0.203


Based on net lift there is a 1.4% loss. :huh:

Neither are correct to my calculations. Especially a loss.


Can anyone explain these?

Post subject:  Re: Cam profiles for all models [3 Tech]

i think you can't measure base circle diameter with a caliper, because of the valve lift is present for more than 180degres, to accurately compare a stock vs regrind, you may need a dial indicator set to 0" on base circle rotate to get full lift and a degree wheel to get the valve timming numbers

Ah. That's the missing piece. Didn't even think about that. Thanks

Post subject:  Re: Cam profiles for all models [3 Tech]

No that's not it.
What you did is correct, except your measurements are a little off. The intake lobe and base circle should be a little different than what you measured. I would consider (especially with calipers) a few thousands difference to be normal. Even with a dial indicator, unless it's in the head, (and even then...) it's impossible to be exact.

So what's the difference?
That's why my cams for this application work, and some others don't. Altering the base circle for this application has a big influence on rocker ratio. Unless you actually degree the lobe in the head, there's no way to know what it will be. If you know the effect, you can calculate it and get close, but measuring it in the head is the only way to know what you really have. The intake side is especially troublesome on this cam, and putting a known excellent profile on the intake that would work beautifully on the exhaust would be a disaster in this application.
For reference, cam numbers are typically nominal. It's not out of the ordinary to get slightly different numbers installed than what the spec is supposed to be. There are a few reasons for that, but it's basically tolerance stack up.


Now stop looking for trouble, put the damn cam in and enjoy it :lol:

I plan on it. Now if I could just run 8psi with it is be happy.

Just popping in here to give a little review of the work Mike did for me.

A couple months ago I decided to resurrect my 87 sprint, and being the gearhead that I am, I couldn't leave everything stock. After deciding to swap the stock carb for a weber dgv, I got the wild idea that a bigger cam could really wake things up. After doing some searching I found Mike's page here, so contacted him with nothing more to tell him than 'I want a big, street-friendly cam for my daily driver'.

After answering a few questions for him, Mike suggested that his 226/395 grind would likely be the best for what I was looking for. Unfortunately he did not have a core to grind, so I had to ship my cam to him to be ground, but the wait actually gave me time to get the engine cleaned up and re-built.

When I received the cam I compared it to some pictures of the cam be!fore shipping and could definitely see a difference. Once I got the cam in the head and got the lash adjusted on the valves the difference was even more apparent as the adjusters were almost at the max adjustment!
Q
When I finally got the engine started the first thing that happened was my wife asked 'is it supposed to sound like that and shake so much?':twisted:

The difference between the stock setup and now was immediately evident on the first drive, and I hadn't even gotten the weber properly jetted yet. Very good power throughout the powerband, definitely put a smile on my face. As the rings seated and the compression came up a little even more poop showed up, and once I got the weber dialed in I have to say I am VERY pleased with the results.

Throughout the entire process Mike was quick to answer my questions and was a great help, all in all I would have to give him five stars out of five, for excellent service and product.

for SOHC 16 motor. can u do a 286D 9.6mm lift cam?? Duration is advertised duration, dont know the actual duration. Had a set of those cams done for a Toyota 4afe and it pulls hard.

That's like comparing apples to oranges

Post subject:  Re: Cam profiles for all models [3 Tech]

yes, but i would like the same spec to try for myself.

Author:  suprf1y [ Sun Oct 27, 2013 8:35 am ]
Post subject:  Re: Cam profiles for all models [3 Tech]

The advertised duration number doesn't really describe the amount of duration in a way that is meaningful for me. I don't have a grind like that now, but I do have some profiles that will probably work. It would take some work to develop into a useable cam. If you're interested in paying for that, I'd be happy to do it.

The problem with this application is that there is very little interest in a serious performance cam, and you are limited in your use because of the short valves, and little springs. I used to get a lot of interest from India, but they didn't want to pay for anything.
