Don’t post much here but was looking forward in breaking 800whp on my ls3. I currently have a novi1500 unit with a 3.8 pulley, BTR stage 4 n/a cam, Single nozzle Methanol injection spraying m1 at full blast. I’m currently on stock fuel pump with a BAP, 80lb Bosch injectors making 700whp on 8lbs and 599torque. Plans for this winter is clutch, BTR CPP jam cam, dual nozzle meth injection,3.4 pulley, Ati super damper,and fuel system . Would that be enough to get me closed to 800whp? Not trying to go e85 at all.

closest place available is 30+ miles and from what I have read that you need to have injectors cleaned if car sits for a while. My car sits for a long while sometimes especially winter time.
That cam must be helping a lot because no way a 3.8 pulley would be doing 700rwhp otherwise, IMO.
Should be pushing that bottom end pretty good once you get all the new stuff done. +10% and 3.4" should be pushing that blower to the max. I'm running a 3.25" now but with the stock size balancer. I've been thinking about doing a +10% lower and 3.4" upper which should help a little with belt slip and still be a little more RPM than it's setting now. I'd need to do the math and make sure it won't explode, though.

I am currently on a stock balancer with a 3.8 pulley as well. I have thought about going to a 3.6 alone. Would that give me 12 lbs? I didn't want to go too crazy. I have a BTR centri cam that I plan on swapping in eventually. Also have a meth kit I am going to install. Thought about just dropping a pulley and adding meth. Are there and pros/cons to going with a different balancer size?

I’m sure the cam is helping a lot, I was making 490whp and 465 torque before the blower and methanol. Yeah it’s a 3.8 and it made 699whp. That’s my plan this year everything I mention and I’ll see what the car will make after that.

I doubt it unless you have super restrictive exhaust or something. I see 13-14psi with a 3.25" pulley and stock balancer. I would think a 3.6" would be a decent amount lower but I've seen PSI numbers all over the place so I'm sure it's not impossible. Keep in mind boost is just a measure of restriction. That's why people "lose" boost when they do better heads or exhaust, etc. They aren't losing airflow/cylinder pressure.. there's just less resistance to shoving all the air in the cylinder.
There aren't really any cons of going with a larger balancer... other than having to pay for it. The plus is you have more surface area on the balancer, so better grip.. and you can use a larger upper pulley (so more surface area/belt grip on that end too) and you get the same blower RPM in the end... it's a win win IMO

Whats the need for running the 10 overdrive pulley? Im currently on a 3.25 upper pulley and stock summit lower pulley on E making 805rwhp with 1320cc injectors and an ecs stage 1 e85 fuel system. All that is on a 6 rib setup. Making like 13psi i believe. I definitely could have made more but my tuner wanted to stop at 805rwhp but said if i wanted more, just come back and we can turn it up. I'm so tempted to go back and make it 850-860rwhp. Also on a stock converter with a custom baby n/a cam. I plan on getting an FTI 3200 converter installed over the winter. I planned on upgrading to an 8 rib setup but i might hold off on that for a bit since i dont even think i really need it at the moment.

You would be fine just making sure you are flex fuel tuned and running 93 through the car whenever the car will be sitting and then add e85 when you are about to drive it. The 93 would clean out the system of e85 every time. I make sure to drive around on 93 here and there to flush and clean out the system.
I've never had mine on the dyno but I have a hard time believing I'm making 800rwhp or anything that crazy, but there are certainly nearly identical setups to mine that are showing that level on the dyno.... there are a lot of loose dynos though so I don't really trust every sheet I see.
Mine is ECS kit, E85, blower cam, 3.25" pulley, 13-14psi boost, etc. Maybe I'm making more than I think, who knows.

how big are those dampers again? 8"? 8/3.25 x 3.61 x 6'500 = 57'760. 10% overdriven. they say speed on the novi is critical.
The IW 10% OD one says 8.125", so 7.35'ish I guess would be the stock size? That gets you down to basically maxing it out with the stock damper size. I've heard the same that these 1500's are awesome but don't like to be overspun..
