Share Your Performance Mods and Resulting RWHP Figures??? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Z28-TX · 08-02-2016, 10:02 PM

Greetings!

I've been in contact with several Performance Upgrade companies and they all seem to want to sell their standard "Package(s)". When I share with them that I'm targeting a specific HP number to stay with in NASA ST2 & TT2 HP/Weight guidelines it seems it's still the standard reply.

I'm targeting 550 RWHP (Dyno-Jet). It seems I should be able to accomplish that with the right cam, header, tune combination.

Would value some feedback on others modification results. Particularly if you've netted near that 550HP mark.

Also, any recommendations on San Antonio or Austin area Installers / Tuners welcomed.

Vengeance Stage V package netted me 570 on the dyno.

I4toV8 · 08-03-2016, 12:48 PM

Kooks LT (No cats)
Msd Atomic Intake Manifold
K&N Intake
Tune by Cunningham Motorsports on their Heartbreaking Mustang dyno
494/454

Robbie1227 · 08-03-2016, 01:02 PM

American Racing 2" ceramic coated LT headers and X-pipes, Taylor red performance wires, NGK plugs, and a dyno tune got me to 492 RWHP and 455 RWTQ.
I'm most likely doing heads, a cam, an atomic intake, and a new tune.
My speed shop says I'll be 600 RWHP plus or minus 10 HP
If they are right, I'll be in heaven!

IMHO, these cars perform better (for most of us) on the racetrack with motors built and tuned for big, flat(ish) torque curves......and reliability. Peak hp builds are tougher to drive fast at the track. You can probably get your target w/o new heads, but I'd go ahead and get some (mostly for reliability). Add a conservative, roadtrack oriented cam and you'll be there.

It has been over 2 years now since my work has been done, so I do not fully remember all specs but my final numbers on a dynojet were 605 rwhp 555 rwtq.

Ported Heads
Lg long tube headers
X pipe
custom cam (dont remember the grind)
Fast intake
NW Throttle Body
Fuel rail
Larger injectors
e85 conversion
Double valve springs
Cromolly pushrods
Titanium retainers
Comp cams roller rockers trunion kit

I am sure I am missing some small components, but the final numbers rock and with the spray, the numbers are 770/760 (175 shot)

Monster Motorsports in Davie Florida did my work, Matt is the best!

Foxrus14 · 08-03-2016, 02:01 PM

Trick Flow Heads
Cam
Air raid intake
Kooks LT
Kooks Green cats
Darton Sleeves (Cracked my block)
Weisco drop ins
608RWHP/530RWTQ

Got rid of everything Hennessey on my car... Hennessey is junk!

Need a different cold air its choking the heads...

Stephen12ZL1 · 08-03-2016, 03:06 PM

Advanced Induction Heads
B-3 cam by Race Proven Motorsports
MSD atomic airforce intake
no cats
American Racing 1 7/8" headers
NW 102mm throttle body
ERL short block due to damage on cylinder 7

575rwhp/500tq...this is the best after at least 12 dyno pulls and it was really heat soaked. The cam is a little peaky for road course action but works well enough I'm not changing it. A Katech torquer would most likely be an ideal road course cam. If the car were fully cooled off and the tune was more aggressive my #s would most likely be in the 590/520 range.

I'm a little north of you in the DFW area but I would be more than happy to work around what you are needing. We have been road racing for years, and one of the main things we do.

I have no issues building a package that fits within what ever rules you need to meet.

Hit me up anytime, we have a number of killer summer specials right now for installs on cam and exhaust work too!

Has anybody had clearance issues with 2 inch headers?

ARH fit without issue to my knowledge. Mine are 1.875"

Doubleblank · 08-04-2016, 08:59 AM

I run 2 in ARH w/o any problems.

Likewise and no problems with my 2 in ARH's. As a precaution I did add heat shield "socks" to the plug wires though.

andig · 08-05-2016, 12:00 AM

578 rwhp and 532 ft/lbs tq.
Mods are:
2" ARH long tube headers with x-pipe and no cats
Ported heads
BTR Stage 3 cam
FAST 102 and Nick Williams 102 Throttle Body

Nice lumpy idle but very smooth and responsive and definitely a lot more grunt mid and top end. It does sound borderline offensive though (but I could always put the exhaust fuse back in which tames the sound down a bit).

All work done by Jerry Aikman in Cedar Park and I wouldn't hesitate to use him again.
