Or the 400 ft lbs at 3k

Hopefully with the TVS2300 I'll break 550 ft lbs or better at 3k. I saw a GTO with a 2300 make 600 ft lbs at 3k and a max of 638 ft lbs.

sort of peanut gallery two cents here... but people are saying the 112 is as good as the bottom end can take. Isn't part of that due to the amount of heat the 112 makes at the power levels people are running? It is overdriven quite a lot, which means heat and probably pumping loss. Wouldn't a 1900 or 2300 or whipple, etc at the same power level be putting less strain on the engine, thus you could make more power safer on the stock bottom end?

I guess to put it another way, if you spent $4-5k on the 112, there isn't much you can spend the other $2k on because the 112 is on the ragged edge already. So if 450whp is the goal, it seems like a winner. Otherwise it seems like a non-starter?

You can build a completely new LS3 stroker with new heads, intake and clutch for right at $10k when everything is all said and done. You might also want to think about building a low compression one for future boosting when you want to be around 800 rwHp.

sell him your 418 stroker...

i think it's time that LS2 saw boost anyway.

High IAT's definitely play a factor as you cannot run as much ignition advance or you risk detonation. However, once you really start moving higher volumes of air the increased cylinder pressures will destroy the cast pistons and powdered metal rods.

If you want 100HP go with the Maggie. With $7k you can find a used maggie, buy a custom cam, and heads and still be under the $7k budget. Honestly if you shop the deals you can get a brand new maggie, cam and heads and still be slightly under 7k. You already have the clutch, rear end, etc. so I would just go that route. You would be right around 550rwhp if not a tad more with the right setup on a maggie, but like others have said, you will be peaking it out.

I would personally take the setup you have now, maggie and custom comp cam with a really good tune and have one hell of a daily driver and be done. I have yet to see someone with a big blower, twin turbos, or procharger put down anything impressive other than a dyno number from here. I would like to see some 1/4 mile runs, standing miles, road course, or something. All I have seen is dyno runs, revving in drive ways, and driving in circles in a parking lot.

^^ I dont think ive seen anyone make 550rwhp on a 112. And if they did i bet it would be falling on its face up top big time.

What made you go that route?

My Stage 3 clutch should take the abuse of an LS3 stroked. No? I think they are rated at 700hp. How much HP are you putting down boss?

Was this GTO a stock engine??

I'm waiting for you to tell me how to adapt the TVS2300 to a LS6 so I can go that route

check out ichpen on CF he has already done it using the GTO box1 kit and mp112 box2 + some minor custom pulleys and bracketing.

I plan on doing some 1/4 mile runs at some point. I need some drag radials to be able to take off at XXXXrpm.

So with my LT headers, if I got a MP112 and a better blower cam (or do you keep stock cam, I've read it's a decent blower cam) You guys think I could get close to or hit 500hp at the wheels? And/or underdrive it?

Or like Mossburg said......find a used MP122, (what heads?) and custom cam, and be good for a little while?

The MP112 with a custom CAM, headers and 10% OD balancer with a good tune should make 500 rwhp.

A box 1 cost 6k. I hope to do this for half that.

Is over driving worse on the S/C, engine internals, or the accessories? Or bad on all of it?

Onefast V

iTrader: (3)

That will be awesome. The only problem is sourcing a used TVS2300 or 1900.

Onefast V

iTrader: (3)

the 10% OD should not affect the internals as the crankshaft is what drives the belt and you are changing the size of the pulley that is turned by the crankshaft. As for the the accessories, I'm not sure how it would affect their longevity.... I would assume it wouldn't being over stressing them as generally accessories are run well under their design limits.

Yeah I never priced a new head unit only. Might be worth looking into.
