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

knockout_tx 01-08-2013 12:02 PM

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

avenger88 01-08-2013 12:48 PM

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

avenger88 01-08-2013 12:50 PM

Also the headers are 1 7/8 right?

knockout_tx 01-08-2013 12:51 PM

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.

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.

knockout_tx 01-08-2013 12:58 PM

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

knockout_tx 01-08-2013 01:01 PM

I did my G37s there and thought the number were good.

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.

FRChilln 01-08-2013 01:16 PM

On a Mustang dyno I'm going with 562whp:lurk:

knockout_tx 01-08-2013 01:29 PM

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:

wow greta numbers so far!!:thumbs: . . on a smaller cam'd ls7 with stock heads and intake going from a k&n to a halltech picked up 10rwhp with no other mods/tuning. Id imagine on your combo it would be good for at least that. . .If your knocking on 600rw i wouldn't even bother thou, your numbers are great as is. What kinda torque are we talking so far?

justinlamanna 01-08-2013 03:20 PM

tigertank 01-08-2013 03:24 PM
