Who's getting 700+rwhp? How much effort was it? Difficult at all?
I assume Headers, Exhaust, CAI, tune, Pulley, anything else?? Emissions don't apply, I live in Alabama, a lot are running straight X-piped exhaust here...

Heat exchanger upgrades and modified intercooler bricks so they don't melt from the higher heat due to increased boost temperatures.

Pulley, Intake, Snout, Headers, ported blower, E85 and heat exchanger will get you there I'd think. If you want no E85 then you'll need a cam to break 700 wheel.

Keep'em coming... Thanks...

i just dynoed one which did 699WHP STD.. 682 SAE. The car has ARH 1 7/8 LT, 2.6 upper pulley, 14% lower pulley, magnuson HX, modified bricks, larger inlets, FIC 850cc injectors, Faster Proms Thermal Plates, Expansion tank, 102mm TB, Synergy 4.5" CAI, and a Ported Snout to match it. The fuel used is 98 RON which is equal to 93 in the US

so just one more thing to the top combo like:

E85
Ported Blower
BTR 3 camshaft

Any of those will let it exceed 700whp

A simple search would reveal hours worth of reading that would answer this simple question.

well, i just traded my 1100whp hellcat for a 2010 zr1 with only 4k miles and i dont regret it at all. I just paid almost 16500$ for the mods on my zr1 from GKzr1 (greg kong performance) except for the injectors and fuel system. it depends on what are you planning to do with it... bolt ons or bolt ons with heads cam ? if you are staying on the 700-800whp you could do bolt ons for less than 6 to 8k $. now why did i got a quote of approx 17000$ is because im planning on
strokering it in the future with nos so i dont have to pay anything more.

my mods from greg k are :

ported supercharger
lpe snout ported for 102mm tb.
102mm tb.
intercooler bricks.
upper pulley 2.35.
heat exchanger from edelbrock.
greg k custom ice tank
CAI
flex fuel kit.

mods that i bought are:

alky meth duel meth kit (15 and 5 if needed) =20.
160 therm
8.5 msd wires
d3 intercooler inlets
id 1300 injectors
fore innovations duel fuel system ( good for 1500hp)
ARH LT headers 2'' x 3'' catless.

my mods are good for 1500 hp but unfortunately im doing bolt ons for now till my other engine gets done.
I hope that this helps you finding what you want.

sorry for the spelling im not that good in english lol

spiralc5vette

My zr1 just dynoed 700 hp on the dot and 692trq on 14.8 psi
4.5" synergy intake
102 nw tb
2.55 pulley
Lpe ported snout/ported supercharger (greg from kongperformance)
850cc fic injectors
E85
2" kooks
And modded bricks
Hope info helps 👍🏻

Talk to GKZR1 he has built multiple ZR1s so he knows what the most cost efficient mods are to get over 700whp. Shouldn't be too hard.

It ultimately depends on what you're willing to live with on the car. You'll need full bolt-ons with the addition of one of the following on most dynos/tunes:
- Camshaft
- E85
- Methanol injection

We have done it each and every way possible, but ultimately comes down with if you're comfortable with a cam, using E85 when you want your power, or keeping up with methanol in the car to make it.

Pretty much where i'm at now lol. I'd like to pulley down and add meth. Not sure i'm up for changing the pump every year, winterizing, and buying/refilling.

Can'tHave2MuchHP

I say screw the meth and do E85 if you have local E85 stations. If not, then stick to 93 and put a cam in it. Meth would be my last option on the table personally as I can't feel safe knowing a jet of fluid on a small tank is protecting my engine/making me power. Your choice, none of them are bad options, it's a ZR1

Meth kit maintenance is much less of a hassle then dealing with a camshaft (**** gas mileage, driveability "quirks", valve spring swaps every 20k etc etc)... Use a good meth kit like Alky Control, send the pump in every 2-3 years for a $100 rebuild round trip. (Hell I went 5 years before my first pump started leaking...lol)

There is no reason to do a cam for 700 rwhp... honestly I wouldn't even do meth for that, just a GOOD fuel system, flex fuel sensor and E85. Yeah you won't make 700rwhp if you happen to be on 93 vs E85 but....thats much easier to live with then cam BS.

All these shops like to pitch cam sales because of the parts profits and massive labor charges, (especially on LT4s, OMG).

What's funny is, we put LS9 cams in 6.0 truck motors with turbos and easily make 800rw+

Can'tHave2MuchHP

Yeah great points. An E85 conversion would probably be the best options however for me and a decent amount of other people out there, it wouldn't work too well because of the lack of E85 stations, and you'd end up with a 650whp bolt on car, but like you said, it drives like stock(ish).

You seem to be a non-cammer, that's fine. I'd just maybe go for a cam because I like the simplicity of being able to run on 93 still and the sound of a cammed Chevy.

Like I said, can't go wrong.

ajrothm

Yeah if there is no E85 available, then meth is your only option....You can make plenty of power on 93/meth. Just do a GOOD install on your meth system and keep close tabs on everything. I made 900 rwhp on 93/meth...

As for cams, I like cams in the right application, it definitely can increase the efficiency of the engine if they are done right. The problem is, most people want to put the biggest cams they can get in there because they want the "sound"....and thus creating driveability quirks, shitty gas mileage, low vacuum (which means shitty brakes) etc. Also bigger cams tend to increase the peak power numbers the most and everyone wants a big dyno number these days.

I went from a little baby cam (226/238*) that made 900 rw and trapped 151 mph, drove pretty well and had decent vacuum, to a custom BTR cam (239/252*) and it drove like ***, had terrible vacuum, which made the brakes suck, and made no noticeable improvement in MPH....and it lost a good bit of throttle response and off idle power.

So yeah, I've learned a lot of lessons in cams in my years.....for mild stuff that you drive a lot, I prefer stock cams. Over 700 rwhp, you'll need a cam for sure. (I'm talking boosted stuff here.... for NA stuff, you'll need a good matched cam from the get go)

Many ways to skin a cat.

No heat exchanger or expansion tanks at that power level? How has that worked out for you?
