List your setup whos got the most power

[SMCBUILDERSINC]

All these awesome, killer engine combos are making me dizzy and I love it. But im getting confused as to who has what and what type of work it takes to achieve such power.

Maybe a list will help everyone to see just what a stock bottom end can handle wheather it be a creampuff or not. Lets get the dyno sheets out too, this is the time to bragg.


Lets have everyone mention there tuner, max horsepower and torque and list the modification needed to achieve that power. Also, state if the heads have been worked or if the bottom end is stock or modified ect.

 

[Dr Roof]

I have the stock bottom end with a DLM Supercharger system. I have bellanger headers and Corsa Exhaust No cats. I have no fuel cell and make a 850RWHP and Nearly 900Ft/LBS Torque. Tuning is everything! Of course that is in The DLM Computer.

 

[SMCBUILDERSINC]

So the forged pistons are strong enough to handle that type of power, how about cast?

didnt ls1motorsports tune your car?

 

[Vic]

I heard cast pistons are good for like 700 HP, thats it.

 

[Torquemonster]

Dr Roof - awesome numbers for stock bottom end (even for a modified bottom end)....I assume the bottom end is blueprinted however?

If not - then the V10 is obviously built to 200% better tolerances than any of the muscle V8's ever saw. I'm also impressed the stock rings seal so well.

Check the record keeper section of this site.

To throw my $ 0.02 in....my 97 GTS makes 776 RWHP @ 969 RWTQ, thats 910+ HP at the flywheel @ over 1100+ TQ.

Engine has Stage II Cylinder heads, Nitrous Camshaft, Rockers, Headers/exhaust, and our NGP Nitrous System. Stock bottom end, clutch, and gearing.

Compare the above package with it's price, turnaround time, drivability, power, torque and PROVEN multi car, multi occasion 9 second performance and a clear choice begins to emerge. This ain't the end............

550 CI nitrous fed beast coming soon!

ls1 jUST SERVICED MY CAR! Rob did not Tune it! Not sure where you are getting your info?

Not true for a DLM supertuned system. DLM has many cars with cast pistons making over 700 rwhp. my car has cast pistons but i went the conservative route. i will soon go with the bigger pakage. Ive had no problems not even a check engine light and that says alot when my son drives my car too.

Can a cast piston car take more then 6 or 7 pounds of boost? I believe Sean Roe only recommends 5 psi for the cast cars and Paxton says 7.5 psi. So how does DLM get over 700rwhp out of a stock bottom end with cast pistons?

 

[SMCBUILDERSINC]

I meant to say LBS of boost, I dont know why I was saying PSI....

 

[Mark Red GTS Cooper]

Do not go over 4 lbs of boost with cast, 5.5 to 6 lbs pounded the ring land (SP) on one of mine,, Cast BAD,, Forged GOOD,, Hyperetectic (SP) S_hit

Save yourself the money, do it right the first time!

Any engine can blow up with only 2 pounds of boost.it depends on the tuning. The boost number doesnt matter as much as the a/f and if the engine is seeing detonation. i dont understand why nobody post dyno a/f or other important information ohter than dyno numbers ?

[Gerald]

pardon me for being dumb, but what exactly does a/f ratio mean? does a low #or high # indicate false readings because a motor was leaned out or made to run rich? If so, does that issue cause detonation? No flames, I honestly don't know!! what should the a/f ratio be at?

[Dr Roof]

I posted My air Fuel Ratio and I think it is extremely safe and 11.0

 

[SMCBUILDERSINC]

I believe that the lower the number the richer the mixture is and the higher the number the leaner it is. So 12.5 to 1 or 13.5 to 1 would be pretty safe for a supercharged car. Ive seen some tuners run a richer mixture which is safer but it does take a few HP away to some extent. The leaner the mixture the better chance for detonation to occur. Im sure someone will be able to correct me, but I believe this to be fairly accurate.

 

[Dr Roof]

So if I lean my car out I could have Considerable Gains.

We need to add the air fuel ratio to dyno graphs for accurate comparison?

In many circumstances yes,

As a majority engines like to see 12-13.00 a/f mixture to achieve maximum power. The only problem with dialing you mixture to this level is making sure that the fuel used is high enough octane or you will hurt the motor. But from what I have seen the difference between 11.0:1 to 12.5 to 1 on an 800hp car can be 40-50 hp at the wheels easy.

 

[ronviper]

Dr. Roof boosted cars love lots of fuel throwen at them, you will see turbo and supercharged cars running rich. Try some dyno pulls adding fuel and taking fuel out, you definately will make more power adding fuel.

 

[Mark Red GTS Cooper]

My pistons were hammered in a non lean condition, my A/F was fine!

Come on guys we need to summarize more engine combos...Where is everyone?

 

[ExecUtron Technologies]

I've got the DLM Stage III+ system. I'm pulling 846rwhp out of a GEN-1. I received new fuel systems (including supplimental Fuel-Cell for boost injectors), extra computer, heads, exhaust, Supercharger, and a lot more. New running gear as well. I don't have nor use NOS. I run 96 oct gas in main tank, and 105 in boost tank. Doug could have pulled a couple of hundred more HP out by over-spinning the blower (more than 15 lbs) and running a different fuel ratio, but that would not be something to warrant. My car fish-tails at 150mph, and kills ever bike I'm up against. Doug offered to add some new technology to my car to increase the HP by quite a bit more. I turned him down. I finally got the answer to the question: "Is there such a thing as too much horsepower?"...

My next Viper will not have more than 850rwhp. I think that's the optimum number!

Roof Doctor,

Your A/F is fine and SAFE! Of course, one day you'll get a little bored with making all that power and lean her out a bit to find that new found love...More POWER.
