1999 SS

iTrader: (3)

i am currently running a 224/224 cam in my m6 99 SS with 3:73's and want to go bigger but still be streatable. what i mean by streatable is A/C on hot days in traffic without stalling decent powerband down low so i can cruise and rough idle would not be a problem.
i was recommended a .228 .230 112 lsa, how would this cam compare to my .224. do you guys have any other recomendations and how would they compare to what i already have.
this car is only gonna see the drg strip maybe 2-3 times a year so i need a cam that is not very peaky and have some good streat manores(?).

i am currently running a ls-6, ported TB, 85mm MAF, decked and ported heads, and custom LT's with no cats and dynoed at 372rwhp and would like to be at least 400rwhp with just the cam being upgraded.

Go even bigger. I really like my MS3 (237/242 .603/.609 113)

I can turn the A/C all the way up on a cold or hot start and it doesn't miss a beat. It does a little surging and stumbling from time to time but NEVER stalls and the idle is very constant.

I'd go at least mid 230's.

F13 230-232, 595-585 112LSA and you will hit 400 plus no problem. Also you can still have AC on and the idle is great

I picked up about 25 rwhp going from a TR 224 to a Comp 228/230 112+2.

Wow. Any other mods changed? Were they both tuned? Were they on the same dyno?

The F 13 from what I have seen and read is great for the power+streetable combo's.

BTW in my oponion these is something wrong with your combo.
You either have heads done by someone with no porting skills, a awful exhaust, or maybe your car isn't tuned.
If the numbers listed were on a dynojet with a 224TR cam, ported heads, and all the other mods you have in a M6 your at least 20-25 HP low.

Damn near every M6 with a mild set of ported heads, 224 cam, LT's, tune, LS6 intake, and ported TB makes 400+.

I have a TSP 233/239 .603/.600" lift cam on a 112LSA I'd be interested in selling. It pulls to 7100rpm no problem and has excellent driveability.

I'm thing about putting in a 224/228 cam for more low end torque.

AMEN brother! thats exactly what i told the speed shop that did the work almost 2 years ago now and they told me that every dyno is different and not to beleive everything you hear/read and this is on a mustang dyno etc etc ive had them retune the ecm twice since that dyno run because i wasnt satisfied.

Hey 99.. whats the LSA on the 224. I might buy it from you.

i honestly dont remember and the cam card is buried away some where in the garage. i wasnt gonna sell the cam, i have plans on putting it in another ls1 and then dropping that into a vert third gen.

i went from the 224 cam to the F11 228/230 in mine and love it.. i'd say you might wee 12-15hp maybe? Some say more but 10 throughout the powerband would make me happy lol..

The F13 would be a nice choice for a M6 though.. wish i had gotten that now im a A4 also and idle is very good

Oh well... was worth a shot. I just spent 2500 today so I guess another 400 aint gonna matter now.

Both were tuned and run on the same dyno. From dyno run to dyno run I only picked up 3 rwhp, however I went from a 10 bolt to a 9" Detroit locker and from a 12 lb aluminum DS to a 19 lb Denny's Nitrous DS. I figure those 2 mods cost me a little over 20 rwhp conservatively. So all things considered I think I gained about 25 rwhp easily.

No offense, but that does NOT count as saying that you gained 25 rwhp. You gained 3 rwhp. If you are going to claim more you need to let people know the whole story.

For starters thats why I explained the whole situation. I think it's a pretty well known fact that there is a 4-5% loss going from a 10 bolt to a 9". The weight of the drive shaft was increased by 50%. Also there was an additional mod MT DR's weighing in at 28lbs each. Trust me when I say these mods cost me over 20 rwhp.

That's why you dyno'd low. On a dynojet you'll probably dyno about 25-30 rwhp higher (from what I've read in SEVERAL previous threads).

I just installed F14 and am driving it on stock tuning. I AM VERY SUPRISED on how well it drives on stock tuning. And the power increase is amazing! Looking for about 380-390 on stock ls1 intake after tune.
I recomend the F14 and you'd prolly pick up 20 rwhp easy. Just a guess though.

Dude you should go get tuned, you'll probably squeek another 15 horses out of it. Not to mention your probably running lean as hell.

i asked around and got the same resonse in regards to the mustand dyno #'s ,so i feel fine about the HP #'s it's the torque that is on the low side for me at alittle under 325 ft lbs to the rear. and since i dropped the idea of putting a turbo on the car and plan on spraying instead (using it rarely) i want to put a bigger cam in it but dont want to go overboard but am willing to put up with alot for the satisfaction of the gain but dont want something tempermental to make me regret the change.
after saying that, i must add that the f13 cam sounds really interesting. who makes this cam?
