engine upgrades adding a little more power?
Stock ZR! , was just wondering what upgrades to the engine I could add without tearing into the engine maybe just some minor alterations or ad ons to give me a little extra power?

Theres a guy on here that did only the K&N with AHR headers ~ 600 rwhp.
LPE 710 kit should get you 630 or so with an easier installation than the headers.
It is harder to search out results of various combinations now that the ZR1 has been merged with the Z06.

This has been my path:
Bone stock: 510 RWHP
Tuned: 560 RWHP
Tuned & LT Headers (Pfadt): 570 RWHP (small gain because stock manifold flows great, but good sound quality)
Tuned, LT Headers, 2.6" upper pulley, 14% lower pulley, E85 Flex conversion: 675 RWHP
Currently porting snout & blower and moving up to 102MM Throttle Body: Horsepower not measured yet.

My advice, forget headers all together, for the price of headers you could get a ported LPE snout and make 30-40 hp, whereas with the headers you gain virtually nothing.
Two things you said, "minor alterations" and "a little extra power". So a K&N intake and tune are minor alterations and will get you 30-40WHP, most of that being the tune. If you have e85 in your area, then you can double that.
Now for the dilemma. A pulley is really the way to go, along with an intake and tune....but, in order to change the pulley, you need to pull the snout, in order to pull the snout, you need to pull the blower. To go through the trouble of pulling the blower and snout and not get them ported while you are doing the pulley is a waste. While you have the lid off, you might as well play it safe and get the bricks modded.
So lets talk turkey.
Intake/tune =1500.00 (30-40 whp on pump gas/ 75ish on e-85). If you really wanted to be frugal, Attack blue drop in filter/tune = 750.00 (probably 10 less whp than the k&n set up.)
All out- Synergy or Kong Intake/102mm TB/kong ported lpe snout/kong ported blower/pulley/iso/idler/brick mod/tune= figure 5-6k (~120-150 whp gain on pump gas, ~175-200whp gain on e-85)
You can reduce the price by keeping your tb and getting it ported and keeping your stock snout and getting it ported. If you go that route, then keep your stock intake, do the Attack blue drop in and save the 900.00 (k&n intake).

As others have said... the formula for mild mods that do not sacrifice drivability, but provide good gains is pretty straightforward.
Some will do headers, some won't. Some will port the blower snout, some won't. In the end, it comes down to your budget and "how far" you want to go.
I did a 2.6" pulley, AR headers with hi-flow cats, and tune. 632rwhp on 93 pump gas (no E85 near me). I'm happy. Definitely more noticeable power than stock, but for cruising/non-aggressive driving times it acts like a stock car.
This is the package I went with... I've done lots of business with 21CMC over the past 14 years. the LPE 710 kit is a lot like it.

I wont have numbers until spring but this is the route I went :
2.6 Upper Only
NW102
Ported LPE Snout
Ported Blower
2" AHR Headers with Cats
Still need to order :
Kong 5" Intake and MM Catch Can .
I wanted to do heads but I am running out of time. Will have to wait until next winter

ZR1 power upgrades.
Wow ! good imfo. Only thing I have done was the K&N air filter which increased the air flow so much the ECM would not compensate for it so I had to get a tune.
The re-tune is the sticking part for me. Expensive and not many tune shops in my local area.
Thanks great ideas.

2.6 pulley and idler a long with new coupler, i think i have maybe 250$ in those parts and stock snout, tuned by me, easy 30rwhp... no dyno but i'm figuring it's a pretty safe estimate... bang for the bucks i win lol...

This was a K&N filter produced by them but had a different name embossed on the filter and it was a dry filter. The tuner commented on it saying he never saw a filter flow so well.
