There is no torque steer... or pull... but that can be a direct result of the LSD too...

As far as "Around Town" my town roads are 45mph... I dont live in the "city" or block style towns, so my ride to work consists of a constant 50-55mph ride. Only low mph side road is the one that leads to work which is all of 1/2 mile long... and my neighborhood, which is also 1/2 mile or so off the main road.

Ben can you shoot me the simulation you had of that cam...

Mods were, 3500 heads, 3500 lower intake, 3500 upper intake, 65mm TCE, Phenolic spacers, All ported/gasket matched, S&S Headers, 2 1/2 exhaust.

I'm curious to see where the cam lives...

[SappySE107]

I saved it this time:P

[3400-95-Modified]

you quoted me a lot more HP than that before....

NA hp was saying roughly 285-290 crank with the first cam and 275-280 I think peak with the less lift cam

Looks like the turbo cams are the better cams for your setup. Intake lobe off the 1280 and exhaust lobe off the 1331. 216/240 278/289 .517/.568 113 ICL 114 LSA. Peaks at 6500 but 6000 would be fine too. It doesn't drop much to 7k. Loves the nitrous too. If you want to run ls6 springs, I have another grind with less lift that would work good too. Not as much peak power but a little better down low.

EDIT:

Nevermind... I'm the r-tard...

BRAKE Horsepower is the horsepower delivered at the wheels as opposed to the CRANK Horsepower being the power delivered at the flywheel attached to the crankshaft.

Both a measured with Dynometers, but of different types.
Brake is measured on a full car dynometer and crank is on a static dynometer where the engine is not even in a vehicle.

Obviously BRAKE is the one that matters to enthusiasts since we can go to specialty shops and have that measured for tuning purposes.

[SappySE107]

No, both are crank (not sure wtf is up with it saying brake on this one). I don't know what was different with the mods you just told me vs what I did before but heads, manifolds, cam, headers, tb don't equal 290 crank hp. It takes boost, nitrous, or higher compression to get there.

Also, I used the hybrid sim this time around, which uses wave and empty/fill. Wave alone is higher. I may have used it for cam comparisons? I don't know. I have a new version of the software that is supposed to be better so some of it may have to do with this as well. I have more settings now anyway, like the combustion chamber design.

[3400-95-Modified]

did you give me numbers before with a 100 shot of nitrous??

bummer.... this is starting to sound like the cam that wasnt quite what I was expecting....

[3400-95-Modified]

this is what i gave you and that was direct quotes from your responses....

Stock lower end, POSSIBLY shaved heads if it would help and not hurt when nitrous is in use.

Peek rpm probably nothing too crazy, about 6500, I'm keeping the 4t60e so I'm limited to that.

Other mods is ported 3500 top end, 65mm TB, CAI, UDP, S&S headers, 2 1/2" exhaust, and DHP ECM.


Anything else you need to know?

You told me not to shave the heads either so I assume you went with the hybrid compression..

[SappySE107]

Helps if I tell it you have headers...

[3400-95-Modified]

Thats better....

Now I feel better... LOL

[gectek]

ss headers FTW

[IsaacHayes]

The headers are not equal length, or long tube though... Is that taken into account?

Headers and exhaust is probably ~20 to the wheels, what is the cam worth then? Say you are ~200 HP before exhaust and cam...

I think you need to ditch the N2O and throw in some camaro 3.4 pistons

[SappySE107]

No, it does not allow me to enter in each exhaust primary length. It considers them to all be the same.

Attached is the same setup with the stock cam.

[3400-95-Modified]

I am going to doubt that long tube will cause that much of a difference on these motors... maybe a few but not a whole lot. And its all general numbers, none of its set in stone... I can't guarantee my intakes flow as good as the numbers Ben is working with either. This is why over the winter he may see my intakes and heads come his way for some "race port" work over what I have already done.

O btw Ben, a 3500 plenum with phenolic spacers doesnt fit under a beretta hood without removing the sound deadner... lol..

I could have told you that... In fact, I think I've mentioned it before.

[3400-95-Modified]

Which part, the 3500 thing? Its a tight fit thats for sure...
