Nismo, who did the reflash, sounds like a good gain.

 

I want to break or at least come close to the 300 mark. I wanna hang with c5's. I think I should be able to do this with cams.

any thoughts on this? I know alot of you guys think it can't be done but I'm an optimist.

 

You will get close, but I doubt you'll literally break 300whp on a dyno jet.

It's not all about the number though.

cams, cats, and tuning, you'll be pretty close...

 

what do you think without the cams?

 

assuming you get a good tune, probably about 265rwhp (dynojet) ... it seems cams can add about 20hp roughly, which is not much for how much they cost to get installed

 

Yea...cams will get you about 15HP actually - unless you do fuel system mods with them and tune appropriately.

Put gears in the car as well - 3.92's if you want to pick up on vettes....

thanks rick. Everyone seems to shy away from cams though. I know they're expensive in themselves and then expensive to install as well. But, these issues aside, do they cause reliability or driveability issues? and if so, in what way?

 

Well - it really depends on the cams you put in. Your general Nismo cams or JWT cams, usually do not cause much issue for driveability. It is really advisable that you get at least a UTEC though, if going with cams and a great qualified tune.

The real driveability issues come into play with idle quality, which is fixable, and gas mileage issues - if you go somewhat radical other than the standards.

I think cams are a great addition to our cars, especially if your going FI.

I've added headers, intake and exhaust and pulled less than a stock Z on the same dyno on the same day. I know some folks argued for a reflash over a UTEC but since I don't know what else I might do in the future I'm probably going to invest in the UTEC. Look for my post I put here a few minutes ago for more details.

you must've just been in the presence of one of the highest hp stock z's out there...

 

From what I have seen the 06 Rev-Ups are in the mid to high 250's stock

I think he needs a tune to be at 270 or so whp with his mods

Of course the exhaust may be more restrictive than say an HKS unit

If I had the cash burning a hole in my pocket

Rev-Up motor
MREV2 + spacer - 10whp $700
Pop charger w/ air box (cut down the heat soak) - 5whp $100
Longtube headers (Used if you can find them) - 10whp $800
Dual exhaust --- Probably the HKS setup - 12-15whp $1200
Cams 272 or so nothing too crazy (Have a friend help with install) 15whp $1000
100 Shot $700
UTEC (USED) 1100 w/tuning

Figure 290-300whp NA and 400whp or so whp on the bottle (track days) That comes to $5600 total with at least $1300 coming back when you sell to go FI

I think those mods would be a nice setup for a street Z while giving you a "one bite a time" mod list instead of all at once turbo setup IMHO

 

your numbers are high on everything except the cams i think. You would want a HFC or test pipe too.

 

I picked up 19 peak just from the UTEC.....after all my other mods. As far as the whole pro/con with the UTEC....much of it depends on the tuner. Iam very pleased with mine and it made the biggest noticeable difference in the performance of the car. The low/mid range torque gain was significant.

 

I think I'm going to go with the aam reflash on the dyno. I'm hoping they can get me within 1 or 2 hp of what i could get with the utec

 

I see. I have a pop charger, rev-up lower plenum, ur pulley, dc headers, crawford high flow cats, nismo cat-back, JWT clutch/flywheel, TS reflash. I dyno'd a while back and was at 272whp 251wtq after the reflash. I am thinking of swappwing out the rev-up lower plenum for a mrev2/spacer and then reflash again and probaly set the A/F between 12.8-13 and then re-dyno. Then maybe the SAFC-2 will be a good purchase. Thanks alot.

 

Technosqaure. I want to reflash again for a more agressive map. 13.3 is safe but I want to drop it down to 12.8-13.

 

Impressive #'s.

 

Can you use the stock valve springs with the JWT S1 cams? I know the Nismo uses them. I am thinking of doing cams in the near future.

 

I have all the AAM bolt-ons and ECU reflash and love it. You say you are a newb and already getting a lot of mods so if I were you I would probably go for the UTEC and just get Mike(if you're going with AAM) or Shariff (closer to you) to tune the car. I would be willing to bet that you will get cams and/or go FI someday and buying the UTEC now will just save money down the road.

 

I would like to do cams and a SC but I'm just to worried about (and in need of) reliability, so unfortunately I think my modding has to stop after headers.
