TVS2300 Confusion
So I have been reading several threads on here about some basic bolt on's and adding the 2300, but only getting to 660-680whp. That seems really low to me for replacing the supercharger. If just the s/c change is good for ~90whp and most LT4's are getting 575 to the wheels that would be 670 before intake/tb/headers/ actual tune. Leaves me wondering if it is a tuner issue, or a car issue. We all know that the LT4 needs cooling, and fuel modifications to make moderate/high WHP goals. With that being said is it possible to get 720+ before getting into the engine? What becomes the weak point, is it the low side?
My car made 661/709 at the time of original tunning, and went to 647/706 10k miles later on a mobile dyno. I would say that it is a 655whp car. This is with TRIC halltech intake, 15%od pulley, ported tb, headers/x/ overaxle exhaust. If I were to add the TVS2300 could I expect to hit 720+ on pump 93? Would adding Cordes Low side help boost that number or is next step going to be Cam/Heads? I am trying to avoid a cam as right now other than being loud at start up nobody can tell that it isn't stock. Which is my goal to have a "sleeper" (if there is such a think with the Z06) that can hold its own on the street.
TIA.
Also, what is a stock 1750 supercharger selling for now, $1200?

Wow, that seems low considering a C7 Z06 is suppose to make 650/650, if so, why do you say that "most stock LT4s only make around 530whp"?.... I have no expertise and it seems odd that a Stingray LT1 with a SC range is around 530-575+/- as I don't think that would be near a LT4 Z06 at stock is 650/650 even though I have seen dynos with lower numbers and don't understand the performance science I would think a stock Z06 still kills a stock Stingray with a standard bolt-on SC?

I haven't installed the 2300 on my Z06 yet but do have one on my 17 ZL1. On that car the 2300 with supplied 80mm pulley, a CAI, and 103mm throttle body made 664 on 91 and 714 on E85 (actually 66% E).

Many standard bolt on Stingrays with a SC run different amounts of boost so hard to compare that to a stock Zo6. Some stock Stingrays with just a SC will crush a Zo6 other will have very similar power to the Zo6.

I was at 690 rwhp and tapped out if fuel at this stage. I’ve seen some folks just over 700 on 93 pump. The 2300 is far superior blower and you can take it to the next level with low side and cam. Stock 1.7 is a hair blower and will eventually pull timing. The 1.7 will peter out quicker on top end compared to the bigger 2300 which pulls like a rape ape!

Ive had the 2300 for a while but just never got it installed. I think I paid something around 3300 for it used. Which it is currently at superchargers online getting a once over. So hopefully it was a good investment.

Well, my 2015 zo6 has the 2300 Maggie with smaller pulley, 103 snout. throttle body , afe cold air, plugs, with tune only made 651 rwhp and 651 trq.with a low side fuel. The car definitly faster, but I was hoping for a larger dyno number( no headers). Fuel is definitely the issue. I think with the 2650 you would need to estimate more money for upgrading the fuel system.

If that's on 93 octane its not that bad if you still have the stock cam and no headers. The 2650 would probably gain you another 60 rwhp or more and you'd have much lower IATs which allows you to run lower boost and probably some more timing. I went from 770 to 847 on the initial dyno running less boost. Generally once you pass 140 IAT's if its set up correctly by your tuner it will start pulling timing. My 2650 was running about 110-115 IATs going thru the traps compared to the 2300 which was 150 plus depending on how hot it was at the track and never had any knock or pulled any timing with the 2650. You might consider adding a Meth/water kit since you live in a very hot climate. I should mention that was on Vp MS109 and a Aem Meth/water kit w/1000 Nozzle.

I ran 16 psi on the 2300 but when I switched to the 2650 it made 80 rwhp more on 13 psi. I never had it back on the dyno after I went to 16 psi on a smaller 75mm pulley so I'm guessing it was making 875 or so on 16 psi.

did you have a lower pulley also on the 2300 setup at 16 psi?

I was shooting for 15.5 ish psi but really dont want 18 unless fueling keeps up I suppose.
