cams are here, webcams - pics and dyno pics yay Options

I got the 294 grind, which is an overall preformance grind. The other grind they do (the 101) is more for non-stock internals, lower compression, ect., not really what is best for my situation.

the plan

First I need to dyno the GT for the control. Then install, re-shim the valves, new valve seals since we're in there, and then dyno again with some tuning. Then compare the results.

From what I understand (on a 5th gen 5s) this should fatten my power band pretty nice. The mr2 guys get about +20 hp to the wheels with these. Now if I can get at least that with these, it should make a big difference when I turbo...

comments are welcome.

very nice, keep us posted

[Rayme]

Is there a link to those MR2 guy's dyno with those cams? 20 Hp to the wheel sounds almost too good to be true without exhaust, header etc...
These are interesting

dustin those looks sexy has all get out nice job i can't wait to see the dyno from them..also check your PM i sent something to you

[blckcelica95]

where you get the them ,and how much? becuase i could really use the "101" style on my car

[jcbass7]

awesome dustin, those look great, where are you going to dyno it?

[x_itchy_b_x]

wow, this will be cool. new power band woo woo!

[Defgeph]

Very nice. I can't wait to see the results.

[presure2]

hehe SWEEEET D cant wait to get these installed and see the results !!!
then its onto BOOOOOOST!!!!!!!!

Dustin, get some assembly lube before you put those in.

NOT engine oil.
Or Lucas stuff.
Or heavy oil.

Engine assy lube. It's moly based, and will not squeeze out the way oil will.
Will help keep those cam lobes undamaged for break in.

Federal Mogul makes some good stuff.

[Batman722]

here's a side by side comparison with stock cams and the webcams weld and regrind







The lobes are fatter and less pointy as before, allowing more air in and out with each duration.

Rayme, check the stickies on mr2oc in the n/a forum, also, I already have a header, cat back exhaust, and a neo for some light tuning. The more I read about them the more I think I should get 20ish to the wheels from stock.

mad props for being a pioneer with these.

[x_itchy_b_x]

less lift, more duration. sweet.

[Defgeph]

Thats freaking sweet man. I can't wait to see this running.

[6strngs]

less lift, more duration. sweet.

how does less lift help? I would think more lift, or at least the same amount, would be better for flowing air in. I suppose less lift would be easier on the valve train... would that make for a higher revving engine?

[NuclearHappineS]

it looks like more lift, look at the base circle on the web cam, it's smaller/narrower

lift is going to be the difference between the distance on both sides of the cam... so if you grind the base circle down, you need to use larger shims, and that will make the lift higher without having to extend the cam lobe's other side that much ...

Yeah I wanted to say moly lube/assembly lube when you put those in, but alltracman beat me to it...

enjoy the cams !!!

good luck, and with a turbo it will make a difference. if it does make 20hp N/A then that means that say at 12psi when boosted you will be making the same power as someone running 15psi on an uncammed 5sfe with the same turbo.

oh also, if you have some money, this is a good time to buy a 2jzge cam gear (only need 1) and get it machined to fit the end of the stock 5sfe cam...

this way you can install it with the cams at the same time...and when you go to redyno you can optimize your power band (i'm guessing optimum will be around 3-5* of retard) that is if the web cam is timed exactly where the stock cam is...

Less lift would make for lower RPMs, not higher.

Less lift means less air.
The higher the RPMs the more critical each bit of air becomes, because things move so fast.

Dustin, I was wondering about the base circle.....

Do you have a micrometer so you can measure the 2?

If they did make it smaller, that's going to make the job a bit harder.....

[94celicadude]

wow..looks sweet! let us know if these are worth it because i have always been afraid to pioneer these on my 5s...good luck

[x_itchy_b_x]

I assumed it was less lift only because I didnt realize they required larger shims. I see now though, the base circle is definitely smaller.

Any updates???
