Yeah 700 is a high hp goal. Lol

Unreal

Why not go with an easy proven 700+ setup, add 100 shot, or just throw an ECS/A&A kit on and be done? Reinventing the wheel, or trying to be different is a sure way to get frustrated and spend 2-3x as much for same results.

I was just in thought of building a good n/a motor or doing a UPP twin turbo kit. I haven't seen or heard a lot of stuff about that kit

jayyyw

I'm putting down 750+ on a 150 shot and SBE. That's plenty for the street.

You'll change your mind in a few months or weeks anyway, so it doesn't really matter what you want today.

We are in the same shoes my friend! If you want a stock style intake (mamo msd is the best) then you will max out at around 675whp like josh b did.

If you don't mind aftermarket hood, then I'm sure holley hi ram intake could make 700whp. Josh B is aiming to try one and we will see the results. There was monte carlo with a stock ls7 shortblock and ported ls7 heads which also made 700whp with the a solid cam and holley hi ram.

Ofcourse you will need a high CR motor and race gas or e85.

625+ whp N/A isnt going to be a friendly car on the street and 700whp would be flat nasty to drive on the street N/A, 600whp and spray it be done; you'll spend another 7-9K min chasing that 100hp over 600

Innovate

Would Brodix BR7's or All-Pro's that are ported help get there? I have heard of 649 out of some BR7's that are in a road race Z. Not sure of compression but still runs 93 with stock short block.

ZF Six

There was a local Houston guy building a 500ci for his street C6Z but honestly don't know if it was ever finished. It was originally being done at Houston House of Power but then the owner of the car started his own shop.

^This.

Throwing all that money at the C6Z in pursuit of 700hp NA, or testing out the reliability of a UPP kit, etc. Just sell the car and get a C6ZR1.

You could 700 rwhp out of a ZR1 so much easier, in a package that is set up to handle it so much better....and you'll be money ahead IMO.

MTPZ06

Here's a ZR1 with very, very minimal work done (post #5) that made 655 rwhp. https://www.corvetteforum.com/forums...rformance.html

That's still on pump gas...add DSX flex fuel and E85, and this car is well over 700 rwhp. It would still have great driveability, and be extremely reliable for all intents and purposes. 700 HP NA...good luck with driveable and reliable.


I've seen bone stock ZR1's add nothing but a CAI and Flex fuel for E85, and they gain ~80 rwhp. ZR1 is the perfect platform for your HP goals...it just wont be NA.

NemeZ

Looks like vengeance reached 700whp plus. 460ci, great heads, big solid roller, and a bad a** intake.

robz

Well it depends. The intake manifold can play a significant role in driveability.
With an ITB we made around 700whp in a perfectly streetable street car thru 388 cubes and 4.10 gears 10 years ago.

Millenium Z06

I'd agree with that but how many people are going to go with an ITB system

441LSXTT

So who is a good engine builder?

MTPZ06

Wonder what the power curve looks like with such short runners. No doubt it screams up top, but wonder what the low-end looks like...which of course 460 cubes can help with to a degree.

Millenium Z06

Exactly, sacrifice low spewed power for the right to claim 700+whp then get promptly beat by every 600whp in the area

RamAir972003

Ill take you to Reher Morrison if you want to go.. you will freak out...

Josh B.

I got 682rwhp through my Mamo MSD on an honest dynojet. I think that's about all a plastic intake is going to flow; more cubes wouldn't raise the peak hp number much IMO. My combo is "streetable" as in, it drives on the street ok if you keep revs above 2k rpm, but I would not call it "street friendly". You get used to it.

More cubes wouldn't do much at all for peak hp. Torque would increase everywhere, and drivability would improve. Cubes would swallow up some of that cam timing.

double06

And Josh would be 695 or 700 hp if he had a super light flywheel set up but then the drivability especially in stop and go traffic would go away. Not to say you can use a light flywheel with a big cam NA car but try driving for an hour and only going 5 miles (pushing the clutch in hundreds of times) on the DC beltway and you will go - why did I do this? Just depends on the end use of the car.
