making 381RWHP should i be making more?
2000 camaro z28

 

I would think. I am making 381 with a Hotcam, no heads, and untuned.

 

Considering the specs on your cam, your hp sounds about right. Heads won't make much difference with mild cams. Also you are running through cats and are not using an LS6 intake. But I'll bet your car drives as easy as a stocker, will pass emmision testing, still gets great gas mileage, starts and idles easy, and runs great........it sounds like a good combination to me.

 

Sounds right to me. Can't wait to get my new cam Thunder Racing 224-112. Along with long tubes, ASP pulley and LS1Edit I should be making around 390rwhp or more. Snake meat is beginning to look very appetizing

 

Was this on a dynojet or mustang dyno. Dynojet normaly will give higher numbers. I have basicaly the same setup and I pulled 408 corrected to the wheels and 416 uncorrected on a dynojet. Did you have your exhaust open or closed? I have flowmasters on my car and a cutout. With the cutout closed I pulled 383 hp but when we opened the cutout we were suprised with the 408. Make sure you are running open exhaust.

 

Oh yeh, I also agree with Goldz. You need to get a ls6 intake if you do not have one.

 

If u are running the cats on the FLP's take them out and u will see some gains there. Look at sig before and after the cats on the FLP's. LS6 intake manifold will help alot too. Although, i think ur car should be making close to 400rwhp even with the small cam.

 

That cam and good tuning alone should net you that kind of HP . There is definitly something up with those numbers .

 

what cam should i get that would make the most rwhp. what kind of hp gains should u see from that kind of cam. I want a stout cam. Should i get a custom grind?

 

Depends on what u want. Are u planning to run NOS or Boost? Are u going to keep ur car N/A? Do u mind if the car lopes or do u want a smooth idle? Do u want to rev above 6K to make the power or u want it before 6K? If u want to go crazy, i would go with GX5-2 on 110-111LSA. U will make crazy power with that cam, but u will need to drill a hole on the TB and good tunning.

 

i am not planning on running boost or spray. keeping it n/a. dont really car about the idle, and w/e rev makes the best power

 

Then go with either the LG G5X-2 with 111LSA or the new TR cam that made 450rwhp with stock heads.

 

MTI was the first problem there.. should ask around.. many people here in Houston do not trust MTI.. Sure some do but I know way too many that dont and that MTI has done wrong..
I wont even dyno at their shop since I have known of them doctoring their dyno numbers..

anyways... I would think you could be making more with your mods but the MTI part messes with the facts IMO... Maybe get another dyno done at another shop...

Or get to the track and see what it does..
