My head and cam package from tsp, they said the heads are on backorder for about 2 weeks , but I went with the stage 2.5 5.3l heads with the Texas Speed Torquer v.2 Camshaft (232/234 .595/.598 112 LSA) with MLS head gaskets, do you guys think I will be over 400 rwhp with a tune? Is this a good set up? He said that if I change my mind about the cam I can call back and chage it within the next few days.

*EDIT* I am getteing the tsp 228R cam instead*

 

I got over 400rwhp with Edelbrock heads and a small cam (220/224), so you should be OK.

 

Sweet, you guys think thats too big of a cam? I dont want to get too small of a cam its not daily driver BUT I still want it to drive good with a lopey idle.

 

Also should I have gone with the stage 1 ported ls6 heads instead of the 5.3's?

 

bump

 

Hmm. Interesting.

 

Based on that combo i would think you want low end and mid range power, if so, you hit the nail on the head. Now if top end is more of your cup of tea, try a Magic Stick cam with ported LS6 heads. Best of luck, either way, your goal should easily be achieved.

 

 

I would think you should be around 410-420 , you will love it ! CONGRATS!

 

You should easily clear the 400rwhp mark. I have an A4 and a more mild cam than that and I am at 419rwhp. I would guesstimate closer to 450 with the MN6 and a good tune.

Sry to bring this back from the dead but how much hp/tq do you guys think ill have around 2500 rpms, i saw a dyno graph of the same heads I am getting from tsp and this guy had a MTI X1 cam w/ the 5.3l stg 2.5 heads (pretty much what I will have) and he only had 175 hp/175 tq @ 3000 rpms but he had 315 hp/ 300 tq @ the same rpm before the 5.3L heads but with the MTI X1 cam. If I am going to lose that much bottom end with these heads a TSP 228r cam then I will get nitrous instead or JUST get the heads, I dont know now. Here is the thread I am talking about http://forums.corvetteforum.com/show...ight=tsp+heads

 

Bump!

 

Bump!

 

TTT again

 

Looks like he gained power all through the rev range. It would be almost impossible for a cam only 5.7L to make 315/300 at 3000rpm. You aren't going to lose any power any where with a halfway decent H/C package.

EDIT: I think you have the curves mixed up. The blue lines are his new numbers. After the heads he was making about 175hp and 310tq at 3000rpm.

 

Just call Jim at swtuning.com, he is located in OKC and I am certain that once you talk to him and tell him what you want, he will be able to help you. He also the guy that I would take my car to have it tuned, he rocks, trust me, I drove from Charleston, SC to get him to tune my setup and it was worth the drive.

Best of luck. That cam alone will probably get you around 400 rwhp.

 

Oh boy after your h/c setup you are in for a big suprise. After i did mine it totally turned the car in to a monster. You are creating a definate GRIN machine. Congrats on the setup best of luck on the install. Don't forget after its all done, go drive it like you stole it

 

Oh crap I did, now Ill have to re-evealuate everything

 

Yes, you need to be discussing these things with your tuner. A competent tuner will be knowledgable in all areas, including engine design and modification. This will ensure you get what YOU want. To be disappointed after you go with the average Joe's advice (as well as the myriad of magazine articles and internet info, some of which is accurate), is not the time to be wondering what to do, after you've spent hard-earned money.

Why would you cobble something together, based on opinions of people that hold no responsibility or cost for your situation, when you have the resource of knowledge the tuner "should" have, and not use it to your benefit? This does not infer that no one on the net knows what they are talking about, but they are not responsible for the cost or results of your situation, and that is everything, as far as I'm concerned. Responsibility ensures results.

I cannot comprehend that there are tuners out there that are not highly knowledgable engine builders, because I contend that if you do not not INTIMATELY understand how it goes together and works, you have no business tuning or modifying it for people.

PS: Do not get hung up on peak dyno numbers, but what you want the car to do. This is a fatal mistake on dailiy driven cars.

Does that process?
