Tell me what you guys think. Hoping to get 500rwhp+ out of this N/A. Tell me what you guys think. Purchased all these parts individually and saved. These are not cheap parts either. They are quality. Couldn't find any shortblock assembled like I wanted and for what I wanted to pay. This way is way cheaper. Tell me what you guys think about it and if my 500rwhp is possible.

Take care guys

Nope. That is over 1.5hp/cubic inch. You don't have the parts, design, or compression to do that. It will be a fun motor, no doubt. 500hp at the tire isn't going to happen with a hydraulic cammed 346. No offense meant at all, you just have to be realistic.

btw--can you send me your phone number again? I accidentally nuked my inbox.

Yea I highly doubt your gonna break 500 rwhp. But if it only make 470hp dont be unhappy it will still haul ***.

FEAR THE LS1

I'm guessing your car is a M6.. I'd have to be realistic and say that you could pump out a solid 450 RWHP with that setup and a 6 speed. Thats still some killer power, but 500 RWHP for a 347 I think you would have to go with an extreme solid roller motor. Futral laid down 520 RWHP with his insane SR 347.

If you have an A4/A3 then you expect alot lower dyno number, however that doesn't mean the car will be any slower.

Just use the Dyno to tune the car and use the 1/4 mile to measure its performance.

Good luck with the new setup, always fun to build a new motor.

It is a dream though?! LOL. No offense taken man. Yeah i will send you my number again. I was wondering why no call last night but figured you were busy. As for the power, You watch i will push that 500 plateau you just wait and see. I will change my name from 1998redcoupe to 1998redblur! i am gearing up for this summer and getting ready for our race. later man

there have been several hydrolic 346's to break the 500rwhp mark. it can be done but it won't be easy. you will need some really good heads. absolute put out a couple of them with ls6 heads that flowed 320+ cfm with a 210cc runner (they had incredible number through the intake if i remember correct as well). good luck to you and keep us updated

1998redcoupe

You guys think that i should push 450 but not 500? well i can hope cant I? I will give it an honest try though for the 500. believe me if i hit 450 at the rears that means i would have well over 500 at the fly right? I could live with that. 450? that will work cheer me on guys

DenzSS

Yup, you'll be over 500 at the crank with little trouble. 500 crank is 1.44hp/cubic inch. Tough, but doable with your motor. 1.5hp/ci and over you have to get exotic, either through engineering, materials, or most likely both.

Hell, if you're that optimistic what do you think my 408 solid roller/lsx/12:1cr will do?

1998redcoupe

I think it is possible too. I THINK though. I will let you all know though. At least a 450 is possible i firmly believe. 500rwhp on N/A is my goal on basically stock displacement. I have seen and heard about this being done a couple of times by big name tuners, but I am just a regular joe that is going to give this a run.

BOO HOO BRIAN

It just needs more compression and more cam.

1998redcoupe

More compression and cam? I was figuring that was plenty for this motor. how much might be needed? If i hit 450+ N/A,when i hit my juice button i gaurantee i will be in the tens. THE REDBLUR will be born!! Oh yeah and my new license plate will read
either " I WIN!" or " IWNULSE"

Rock on man. sounds sweet. you have good taste. let us see who gets the most HP out of their setup.

blackLS1

Both Cartek and LG made 500 to the wheels in a 346 heads and cam set-up

I made 491 hp and 430 tq to the wheels threw a Moser 9" and 4.11 gears. I had an LS6 stock short block with ARP rod bolts. As for mods I have the Electric water pump TPIS intake and throttle body. Grott headers with a 2 1/2 inch X-Pipe exhaust. I also had the normal bolt on's ASP pulleyDirect-flo lid, stock descreen maf. The car has gone a best of 10.69@ 128.92 mph at a race weight of 3260.

So yes 500 to the wheels is possible and can be done I was running 93 octaine gas and the compression was 11.1 I belive.

good luck with your set-up I'm sure it's going to make some nice power

1998redcoupe

Futural Motorsports just posted that they dynoed 520rwhp on a 346 also.
