I was originally supposed to get 58cc AFR 165's, but they sent me the 61cc ones instead. Will there be any HP loss or gains, or there really isn't a differnece? Is there a way I can make the compensate for it?

You may lose a tad bit of power because your compression ratio will be slightly less now. If you really want to get back to 58cc's you can have the heads milled.

send 'em back, not your fuck up.

will it be a noticeable lost?

You plan on a Turbo system later right?
The 61cc's will be fine. You'll lose a bit of N/A power, but trust me....you won't notice it. [Smile]

I agree with Shaun. You won't notice that much of a difference.

Yeah, for boost you're better off, but not for NA. The difference is probably less than 0.5 MPH, but I don't know how 'picky' you're being with this combo. Your cam may have been ground with for a specific compression ratio as well, but I doubt 3cc will affect it much.

The cam will make plenty of cylinder pressure reguarless.
The cam is.....well....
Lets just say it's about the size of the AFM N41, but will FAR out-perform it on this combo. [Big Grin]

Hey, what do you know about my cam??? [Wink]

Cams....Shaun doesn't know anything about cams does he??? You don't know anything about my cam do ya? [Wink] [Big Grin]

so we'll be going *against* the precedent with this cam 'eh?

The basics of the cam has already been proven in a local's AFR165 combo....I just added a 'touch' more overlap. Unfortunately, the rest of the combo will not be as stout as the local example....but I'm sure Glen will be happy with the results. [dance]

Joe....Imagine if you will, your cam basically reveresed & set on a 111ICL. It's very similar....perhaps a touch smaller at .006 & a touch larger at .200. [patriot]

Shall we call it 'weak nuts #2'??? [Wink]

What other local AFR165 combo? [Confused]
 
Posted by shade-tree (Member # 298) on :
 
I don't think a 230/222 on my car would do anything but hurt power...

edit: I also expect my little cam to come alive with a 150 shot so to speak (as in nice exhaust flow for N20). have to wait and see on that one, not tomorrow but maybe next week.

my next step up is a little port work and some milling.

good luck with the results of course.

dyno it head to head with a B-303 if you want to see what it does for ya vs. a $50 used cam [Big Grin]

Close....it's a 228/222 110LSA 111ICL
The intake lobe is ~15 degrees larger then the B303's lobes @.200. [Big Grin]

It's based on AaronC's first cam. Exact same intake closing & exhaust opening, but with 5 degrees of overlap instead of 1.
His motor put out 340/340, but it had more compression, 1 3/4 longtubes & 2.02 intake valves.

shaun check your pm's and e-mail quick.

Cool, I can't wait to see the dyno&track results in a few months. What are you trying to achieve with the 5^ vs 1^ that hi-tech went with?
 
Posted by Glenn (Member # 520) on :
 
do you think this cam will work well with my heads?

Posted by 93PONY (Member # 60) on :
 
....well that just sucks!
That's the cam I speced for Edelbrock heads.
Send it back. It will not give you what you want.
 
Posted by 93PONY (Member # 60) on :
 
On second thought.....let me do some digging/research & I'll get back to you.

That's an Ed C. style cam....it may get you what you want. I'll get back to you after I speak with the man himself.
 
Posted by st5150 (Member # 51) on :
 
Might as well send back the heads while you're at it and get the ones you really want.

Alright Glen, you're gonna run this cam!
But, it's going to peak a little lower then the other cam & because your car is a pig you're going to have to make a few modifications.
Here's your choices:
1. Get rid of the RPM upper & get a performer.
or....
2. Keep the RPM & get 4.10 gears.

Also, a 70MM TB is a bit big for the setup/weight.....a 65MM will be fine.
One more thing....this is not a good turbo cam for later on. Good SC cam though!

I am sending it back, and getting the original one. It should be here by thursday at the latest. I don't want to change anyhthing anymore. It has been too long of a wait already. I don't want to have to go through the run around with wynnespeed again. Which cam would make more power though?

pick up a B-cam on the corral auction block for $50 yo!

I am going to try this custom cam first.
 
Posted by 93PONY (Member # 60) on :
 
Both cams will make impressive power. The Ed style cam will make more torque & the other will make more HP. AVG power will be very similar. The powerbands will be within 200rpm of each other.

The lobe on that 224 is the same lobe on the other cam...just in a Ford form, not Small-block chevy so it's 4 degrees smaller.

Whatever you want dude. You bring it to me, I'll install it.

Go smoke that B cam.
Better yet, throw it in your setup & see what happens.

I am gonna see if it is too late to cancel the other cam, or when exaclty it will get here. Wouldn't more torque be good for my pig? Also I plan on sticking with the 70 mm and RPM, I might just have to get a super charger later [Wink]
