Heads and big cam....RWHP???( Video on Last page)
I own a 2009 Z06 and just finished heads and big cam. It should be Dynoed tomorrowed, and I was wondering what should the norm be.
I have 102 fast air, 102 throttle body, BB long tubes, no Cats, BB exhuast, and a cold air system. |
What are the cam specs?
What kinda heads & compression? Which cold air intake? Pump or race gas? With a big street-able cam on 93 I'd say between 600-610rwhp is tops. The norm with a moderate - big cam and all other mods is 580-590rwhp |
Cam is Comp 246/259 624 116
Basically a 293lrrComp cam with more LSA K&N Cold air Heads has been reworked, ported & polished Pump gas Checking on compression |
560-610rwhp. Depends on dyno, tuning, etc. Should run good.

Hard to say but probably 580+ id say.
What dyno? What shop? Check your PM's |
I'd say low to mid 580ish rwhp . You should really look into a halltech intake, the k&n is one of the more restrictive on the market. A halltech / beehive would be good for another 10- possibly 15hp
|
Also the headers are 1 7/8 right?
|
Z is at Jtran in Houston Texas( damn rain won't stop)and he has just started the tuning.
He has a Mustang Dyno so I am not sure it going to convert to Dyno Jet numbers. The 2nd feel out run was 585 RWHP and 535 Tq No hard pulls yet. |

Do you think that there would be that big a difference??????

I would get a second dyno opinion if I were you. I have had my 350z dyno'ed 5+ times, the only time it was off about 30 hp (read way too high) was at Jtran. This was in December 2012.

Yes that is correct.

I didn't say anything because on the my350z.com forums they are very respected for some reason (even though they are less than two years old). I knew I would get blacklisted if I spoke up.
My car is basically stock with an intake plenum, JWT popcharger, and underdrive pulleys. The curve that they gave me is totally off from what a normal VQ35DE curve should be. I can send you a scan of the first dyno run (before I complained about the accuracy). Then they showed me a second dyno run that looked normal, but I suspect that was from another car since they never bothered emailing me that sheet. I smell BS in that shop. |
On a Mustang dyno I'm going with 562whp:lurk:
|
My friend did his Corvette at a Dyno jet shop and then went there and he made less RWHP.....and we are talking about a Procharger setup.
My Fin makes 300 RWHP on a tuff Dyno jet i used for my Cobra and lightning. I like the shop and all the new people there, a nice professional atmosphere, They may have gone through some growing pains in the beginning, but I feel they have turned the corner now,and I see nothing but good in the future. However I will double check all my stuff, and thank you for your input.:thumbs:
