what kind of fuel system is needed to support 800 hp on e85? what oil pump are you guys using? when will these cyl heads be on market, sold separately?

3100lbs, 830ish hp crank, and it hooks

Heads cam 6th gens have fun faster times than a 720s

This engine in a c8 would make a 720s look silly

-This car ran E85 with an LT1 Fuel Pump + LT4 Injectors
-Katech HCS/HCP oil pump
-The cylinder heads are now available and sold seperately, here: https://store.katechengines.com/kate...eads-p854.aspx

High 9’s?

Yeah maybe with a good driver, slicks, weight reduction, stall, etc.

Mclaren does it on street tires out of the box and traps like 145mph.

720s would for sure be a little faster than a c8 vette with this motor with the same tires, driver, etc etc etc.

Me thinks you lack the confidence in the Force.... young padawan... First you must take down the 650 then as your skills improve you can become a master.

Once you start throwing that kind of money around, things like lihium battery, carbon fiber rims, a dual inject titanium rod 427 with twin turbo are all within reach and it is not like the C8 is that far behind even in base-model form. McLaren is going put a billion dollars into doubling production to 6500 units a year (going from memory now). Maybe they can do it??? dunno as I'm a CHEVY driver, don't rub noses with the elite. Vette production is 30K to 40K and IMO will rise from there. To me it is American Graffiti. how has enough money to take down the Japanese guys in the Shelby Road Cobra.... Clearly with off the shelf stuff the LT powered C8 is going to be a force of nature, and once some serious cash gets into it, yea 1000+ HP is going to be the new normal for the average C8 Vette owner...

Can you guys just sell porters castings no cnc work?

I currently have a deposit down on a C8 Z51. But I'm heavily considering getting a C7Z, instead. My wife, however, would much prefer that I build my Camaro.

I'm scouring the field at the moment to see what's out there and if I think it's worth keeping the car. I've seen your guys' previous 427 builds and prices. I like the engine but the cost is always a shock. With this engine, you have my attention again but, I won't run the Holley intake, largely due to the hoods required to clear it. Also, how much will the headers from Kooks cost that are required for these heads? It may just boil down to cost and viability, as to what choice I end up making.

9.6@142 at 3400 lbs heads cam 16 ss record so far. still drives it to work. still has radio ac etc. hes a member here. he is hosting fall brawl. in the drag section.come out and see. although he ran 9.6 in 84f 2700 da. he will probably run around 9.4 range at the rental in good air.

yes depending on your stipulations things can change. but now we are going to give stipulations to a 300,000 dolar car vs a Camaro or a 70k vette? all you said originally was that you cant beat a 720s with this motor. not even close to true.

last I seen 720s record on a tire was 9.7. in good air. for 3100 lbs its not making the hp you claim. looks like its making 750 range. Brandon hills 6th gen ran 9.6 making 750hp verified on an engine dyno at 3400 lbs

a 3300 lb c8 with this 800hp motor setup to hook at the track would beat a 720s on a tire. in my opinion. a 3400 lb 6gen with 50 less hp has been 9.6.

you wont be running this motor without a stall converter in an auto either. its going to be way out in front of the 720 both hooking.

Very understandable. I'll shoot you a PM to help provide any information that I can offer.

I was in the same boat not too long ago, It was between keeping my 5th gen or upgrading to a 6th. I am now in the process of building an NA LS9 416 road race engine for the 5th gen...

The 720s puts down 700whp stock and weighs 3100lbs and is MR

What I’m saying is, an 800hp crank c8 weighing likely 3400lbs minimum, is going to lose if they have the same tires. It is incredibly ****ing obvious that I don’t mean unlimited mods with that motor with a dragged out c8 with slicks and skinnies and no passenger seat is incapable of beating a stock mclaren 720s. Why do I even have to say that. Go ahead completely gut your drag camaro and throw some skinnies on, you’ll probably beat a 720s with 500whp.

Acceleration is not rocket science, infact it’s incredibly simple. And a stock 720s has a better power to weight ratio than an 800hp c8.

it would disagree by a long shot. you didn't even come close to covering all the variables enough to call it a scientific fact. you looked at hp (that you extrapolated/guessed from a rwhp number lol) and weight (while still guessing at the c8) and the tire. that's it.

looked right past the stall converter for one thing. and plenty more

and science is still struggling to explain a 650 rwhp 3400 lb car running faster than your McLaren on drag radials.

No its not, I can tell you all you need to know if you give me 4 figures

Whp
Weight
60ft
Trap speed

Acceleration is traction, hp, weight, and shift times, thats it. It’s incredibly simple

How does a dodge demon run 9’s with slicks, skinnies 760whp at 4100lbs? Yet it runs 11 flat on street trim.

Hmm maybe being setup specifically as a drag car has a huge advantage?

I’m fairly certain a 1500hp bugatti chiron runs high 9’s. Lol thinking a heads/cam drag camaro is as fast as a chiron.
