200 206 grind question?

[The_Unforgiven]

I'm pretty sure I'm going w/ the 200/206 COMP cam. Why exactly should I go w/ an IC of 113 as opposed to the 108?

[Dominic]

Without going into all the detail... retarding the camshaft (larger IC) opens the intake valve sooner, and this change in the cam timing makes the little 200/206 grind act like a much larger grind without the inherant problems with too much duration.

Its used a lot in many applications, including the C5 corvette LS1 and LS6 Z06 cams, to get more power out of smaller camshafts than would normally be expected [img]smile.gif[/img] It moves the powerband up, but the sacrifice made in the low end isn't much of one.

with a 113IC, you're only retarding it 1°... its not a lot but its a lot better than advancing it 4° as comp specs it IMO.

Just for the record, Magnus doesn't agree with me on my lift values and IC.

[JAM]

Thanks for the input Dom! From everthing I have read it seems this would be a very good cam, and shouldn't trip any computer codes.

Is anyone else running this cam?

The really nice thing about this cam is it doesn't sacrifice anything below 4,000RPM. Its a very durable cam given the low lift and should perform well if I'm right [img]smile.gif[/img] . I wouldn't mind having one (only I want a 113LS please). ;)

dominic, i have a .507 220/224 114 ls cam 110 ic. tom at ssm recommended this. i also have stiffer valve springs i think thats for the higher lift, my pcm is programmed so the rev limiter is higher than stock, i think this is so i can take advantage of the power that got pushed higher up in the rpm?? since i have all this done do you think this is a good cam for my car? what cam , in your opinion would make my car have a better n/a 1/4 et?

[Dominic]

Slow, thats actually a good cam design. The overlap is about like camaro zachs and even though the duration seems like a lot, it works out well. Due to the extreme duration, the IC is almost right on and I can't find much improvement.

Nice design.

The actual duration is 255/262 btw, and those are the numbers needed to get accurate results in most camshaft equations.

I wonder how Tom is coming up with his cam designs?

cool, thanks dominic, i dont quite understand how you get my 220/224 is 255/262 i trust you and i know you know your stuff when it comes to this, please explain thanks again. i just told tom what my car has done and he said with programming, that is the best cam for me, im glad you think it is a good cam :D

220/224 is measured at .050" lift and up. 255/262 is the measurement from .000" lift.

The next time you talk with him, ask what values he intends to change to "reprogram it" to work with this cam. Im only aware of a few things that can be altered and I'm just curious about what he intends to change.

Getting back to the cam at hand....

Is anyone running this cam?

I have read that a MAFT will help optimize a cam install. Would that be recomended for this cam?

As this is under .500 lift and not an extreme cam as most have stated, would it be safe to use the SLP aluminum roller rockers with this cam?

Nobody is running this cam just yet.

The MAFT is not a cam tuner, its for timing and fuel adjustments. If you're having a timing or fuel problem, then there you go.

I would not run SLP high-ratio rockers with this cam. WASTE-O-MONAY

Tom didnt do the programming, dave buckshaw did it. as far as i know dave raised the idle some since the cam would have slowed it down, im not sure what else he did for the cam, i think he may have leaned it out a little so it doesnt run way to rich with the injectors walbro and cam. i just told dave what i had done and what my goals were and he programmed my pcm, i know he raised the rev limiter adjusted shift points, something about the correct values or something for the 26 lb injectors, took the governer off, adjusted fan temps and so on.

Earlier in this thread the following cam was mentioned from:

the grandprix store 206/212 113LS 110IC grind

How does this stack up to the cam in this thread?

What are some pros?

What are some cons?

[JAM]

anybody? [img]graemlins/burnout.gif[/img]
