SPANKY LS1

Current parts waiting to be installed:

AFR 205s milled .030 (61cc chambers)
Cometic .045 gaskets (~.036-.037 quench)
Comp XE-R 224/228 .581 .588 114+1
FAST LSX 90mm intake and tb

Been doing some figuring, and to upgrade my valvesprings, flycut, and go with a bigger cam (G5X3, G5X4, etc) would only cost me ~$400-$500 more at this point. How much would I be giving up in staying with the above parts versus a larger camshaft? If the difference is 430 rwhp -vs- 450 rwhp or a similar gain, it certainly seems worth it, doesn't it? Just thinking out loud....

Let me know your input/thoughts, Shawn

whats the application and intended powerband.

Fast car, driveable, and fun. Nothing more, nothing less. Not looking to set the world on fire, just want a driveable setup (car is a weekend/sunny day driver only, NO daily driving) that sounds and performs well (both on the dyno and the track).

are you willing to sacrifice some bottom end for top end? thats the question your really asking.

If your thinking of stepping up to the "big" cam (or certainly a solid "middleweight"), and your considering flycutting, (which would allow you to do so), why not go 225's and be done with it.....that is if you could wait

My air dyno on that combo has you up an easy 25 RWHP....(call it 10-15 EACH for the larger cam and the larger AFR 225).

Don't get me wrong....a 205 with the larger cam will still be a great all around player and would narrow the gap from your initial set-up to what I'm proposing, but if you've got the room and have the static compression to make it a viable option, I'm confident the 225's will be worth an additional 10+ RWHP, all things being equal....maybe more, but I will reserve any additional "optimism" till I've strapped my car on the rollers or get to an engine dyno....whichever happens sooner.

I know your probably all set with your 205's and I'm not looking to throw a monkey wrench into your plans, but I think for some of the others reading, what I proposed might get a few people thinking.

One last piece of "general" advice....spend the time and money do to it right the first time (it seems you are already considering "upgrading" and you haven't even fired the first combination to life)....Its cheaper in the long run and you won't have any regrets....hopefully.

Keep us posted...

PS Nice "224" gragh....looks familiar

I bought the 205s for a GREAT price, so upgrading to the 225s isn't really an option, between the $$$ and the wait. I guess what I'm asking is this: I'd probably be happy with the power of the 224/228, and would LOVE the driveability. But at the same time, if there is say 20 rwhp/20 rwtq to be gained with just a larger cam, thats a STEAL for the few hundred dollar difference. All else being equal, I'd prefer to keep the 224/228, but don't wanna lose out on some cheap HP.

I'd be curious to see what you would dyno Shawn.

****, the way things are going shawn will have his car running before mine.

SPANKY LS1

iTrader: (24)

With what, the 224/228 or the G5X3?

I'm still trying to catch up to your year old numbers

Either way, it should be running in the next week or two.

**** man, my head port is almost 3 YEARS OLD now. Hopefully you can catch my lil ole Stg 1.5 dyno #'s with the big bad AFR's

jk man, just bustin your ***** a lil. How bout putting this together for once

SPANKY LS1

iTrader: (24)

Its going together, or my wife may very well kill me. Seriously, I'm 99% sure I'm keeping the 224/228. I have a LSX 90mm intake and TB, full boltons, etc. If I could hit 440/400+ legitimately through my exhaust (Hooker LTs, ORP, and catback), full belts, and through my 4.30 geared 12 bolt I'd honestly be happy, especially with the driveability of the cam. Anything over 440/400 would be icing on the cake as far as I am concerned.

This thread was more of a hypothetical situation, I'm just thinking of how much (potentially) I'd be leaving on the table. Like I said, if I'd gain an honest 20/20, I'd be foolish IMO not to do it, especially for the $400-$500 it'd cost me....

One of these days I'll keep a setup and prove all of you wrong

how about you get the x3, then call up your ol' pal ed curtis and see what he can do

SPANKY LS1

iTrader: (24)

Believe it or not, I've actualy thought about that. Trying the 224/228, then getting him to grind me a cam that will work with my combo using all the perameters that he uses and see if his cam does any better. I'd really really really really really like to see a back to back cam swap and dyno of a shelf cam versus a custom cam, and like you, it'd be interesting to see what the cam specs looked like.

im hoping to fire my **** up next week so well see how a custom cam does in my application. maybe i'll talk to louis and see if he'd loan me an x3 to compare and dyno wiith :hmm:

iTrader: (12)

The first thing is to forget about dyno #'s The 224 Cam you have is excellent for all around power.I've seen way to many big Cams give up alot of midrange which makes the car a dog from a roll.Your going to be happy with the setup you list
