2001 camaro ss. Stage2 Lq9 Heads. 226/226 .585/.585 on a 112.
Slp longtubes, Slp y-pipe, Gutted Random cats, Loudmouth, Pulley, Mti air lid, 12bolt with 4.10's, Mti tune, Mti polished throttle body.
The hp seems a bit low to me. What do you guys think? Seems like i could have made this much power with just a cam. I'm thinking of throwing out the Slp junk and replacing it with kooks. Hopefully you can see this dyno chart.

Your numbers aren't great, but they aren't terrible either. Keep in mind your 12 bolt is eating up some power, so pretend they're 420 if you're comparing to the usual 10 bolt dynos you see. I'd expect that cam to do 385-395 by itself, so a gain of 25-35 rwhp through heads is not bad. I've seen dyno sheets that showed a 10-15rwhp diff by getting rid of SLP headers btw.

While I agree the numbers arent horrible, they are just a bit low. I'm just looking for suggestions on how to improve it by about 20 rwhp. If i can be in the 420rwhp range with a 12bolt, i wont complain. I'm going to try kooks headers for one... Any other suggestions? I know its hard to see but does the afr seem ok?

retune, your leaning out alot on the top end. like blake said, your gears and 12 bolt are sucking up power as well. your tq curve looks great, if im reading it right you havee 350rwtq @ 2500! also, from what i've seen of PP heads they really need a bigger cam due to the large port volumes and top end flow. mid lifts suffer a bit. what chamber size did you go with and whats your compression.

Sorry i forgot to post cc and compression... Its 59cc and should be at 11.2/1...
With valves 2.05/1.60

Like Jerami said, you need a bigger cam. Those heads like to breathe especially up top. Your cam might be peaking too low for those heads.

any suggestions on a better cam? dont want to fly cut.

Why not go with a TSP 231/237 or 233/239 cam's.

the 2.055" valves are killing you especially with a cam that small.I have lost all hope in patriot since the last set i got looked like it was ported with jagged rocks..the cnc tooling is insane..but yeah try a bigger cam..but with the 2.05 valves your gunna need to flycut for anything worth while.

There is NOTHING wrong with that cam. That is essentially the same cam as the TSP and PRC 225 cam. I used that cam and made over 450rwhp and 415rwtq.... with a good set of heads. I've installed that same cam on stock headed 01 and 02 cars and made 385 to 395 rwhp with all the bolt ons. If you decide you want to go to a bigger cam, I'll buy that one from you.

then why would my numbers be so low? 408rwhp is kinda week for a h/c car in my opinion.

gomer

iTrader: (13)

You have a Pulley, A loudmouth..which is almost as good as a cutout, a ported TB, longtube headers with no cats, LS6 intake, and tuning. I did a before and after with my 12 bolt and lost around 10rwhp. Pretty much the only difference between your 409rwhp combo and my 450rwhp combo is the choice in heads.

hence the bigger cam to compensate for the lack of flow

Im not arguing that I should make 450 rwhp. I did buy budget heads...Not disputing that. They are better than stock though, and i see cam only cars make what i make with close to the same cam specs..

gomer

iTrader: (13)

The heads on my car cost less than $200 more than yours and came with Manley 2.04/1.58 valves. They are budget heads too. Some budget heads are more CONSISTANT than others. FFHP, MTI, and PRC all make good heads in the $1,500 range that won't leave you hanging.

Your tune is very lean,its starts out around 13.1 and continues to climb.
I'd retune the car....

FWIW my car is tuned with 26 to 28 degrees timing and never goes above 12.8 A/F,Check the sig as u can see my car traps really well for an A4.

abate1224

get the 231/237, you will see a hp increase. i made 435rwhp with those heads and a 231/237 cam through a 12bolt.

as stated before,the patriots have big ports,which is hurting the velocity of the airflow a little.a bigger cam that peaks a little higher would better match the heads,IMO.

leeluther252

It was tuned with the tps falling off, and with 1 wire problem.. (THANKS MTI)

stone4779

iTrader: (2)

what wire?

And you should fix that TPS....could cost you a little hp if its not getting the right reading...of course Im sure MTI checked to see if it was getting close to a 100% open reading....didnt they?
