i agree with u

 

Why don't you look at the graphs I am posting and then make your opinion.

 

I can tell you from having owned an lsj myself... That the guy either didnt get tuned or he didnt get bumped up to the 7000 rpm rev limiter...

let me give you some more advice, a stock ss/sc vs a stage 2 ss/sc has the advantage of staying in gear longer because of longer rpms making it win by 2 or so cars... If both damn cars shifted at 6500 rpms it would be a dead even race!!!!!!

 

that graph isnt even for a SS/SC ..... 130 some hp ???????

dude give up .... everyone on this site knows the lsj makes good power up to 7000 rpms

 

and the tune for that car is off too.... the air fuel ratio sucks ass!!!!!!

 

More











Even GM shows that power drops off before 7k...

 

where the hell are you getting your **** from?? are these stage 1 graphs or stage 2 graphs from the gm stage 2 tune?? Lol cuz that **** isnt, some of the power curves peak at 5500 rpms... get the **** out of here with that non sense

 

Oh my. Tough words for a big man.

These graphs are from CSS and RLFs. Mostly Stage 2 or custom tuned cars.

So are you saying that there is more hp to made up to 7500rpms. Because it is pretty clear on almost all those graphs that the power starts to die after 6500rpms.



This graph is from GM in their GM Performance Parts book. It is easy to see that the power is falling off before 7k.

 

and its pretty clear that the tune that their giving these people are plain ****!!!! Lol maybe my friend you dont drive an lsj haha, and never had a stage 2 put on your car.... You cant start noticing any difference in the car at all till you peak it to 7000 rpms....

 

That is not true.

I had GMS2 and now have OTTP Stage 1. This is my dyno graph of OTTP Stage 1. I never got my car dyno'd on GMS2.



Do you have any personal dyno graphs you would like to share?

That is not true either.

By upping the rev limiter it allows you to stay in the same gear just a little longer. It allows you to take any gear to a higher rpm. Then when you ****, you are shifting into a higher rpm in the next gear. So your power does not fall off as much from gear to gear.

Or the other reason to raise the rev limiter is for better 1/4 mile times. If you are hitting the rev limiter at 7k just before the end of the 1/4 most people will bump the rev limiter to 7200. So they can finish the full 1/4 mile without hitting the rev limiter or shifting into 4th.

 

ok so lets get back to my argument.... The guy who dynod the car if he shifted at 6500 rpms, that would affect his numbers when he could of went to 7,000 rpms?? I believe so

 

OK look at my graph..... see it.... read it.... read it again.....

Hmm that looks like a steady power curve that goes right up to 7k rpms where it made peak whp. MODS in sig.

So I guess im a fluke then?

 

It would not have effected the PEAK hp. Maybe if the dyno operator went to 6600 it might have been slightly higher. But as you can see from his dyno post the operator almost went to 7k and the power was dropping off.




You did't go all the way to 7k. Your HP# had already leveled off. If the run would have went all the way to 7k you would have seen your hp drop.

 

you cant go to 7k!!!! lol thats redline bro you shift at 6900 rpms everytime just like that guy did

 

You can go to 6999! lol

I understand what you are saying. There IS power at 7,000rpms. But PEAK power comes before that with the stock blower and stock cams.

Ok. My Final Point.

Area47. I am sure you know who he is. Here is a dyno graph of his car.

Are you trying to say that Area47 is a bad tuner?

 

lol again... that car made power up to 6800-6900 rpms

 

if u remember your first argument ..... you stated that the lsj doesnt make power after 6500rpm ..... then you are sayin it does make power after 6500rpm ..... get your story straight !!!! final point is .... GM Stage 1 increases the rev limit to 7000 rpm to maintain the usuable power the stock lsj makes after 6500 rpm. that is why they claim 236 crank hp at 6800rpms. understand ?!?

 

he went to rev limit which is set to 7k.... i was standing there, 1 pull.

You said you dont make power past 6500? My chart shows that I did and maybe ill re image it and zoom in and show me the level off bc if there is one its not clear at all.

So am I a fluke?

 

Which? Area's? If so it does make power up to 6800-6900. ON GMR cams!

On the stock cams it was only 6500.

If you remember your first argument you said that the LSJ makes more power at 7k.

Go to a real dyno.

 

well according to GM peak HP stock is right above 5500 RPM.. cause the light's on a stock IRL comp pack ladder tach go off like this peak TQ at 4700 (first light) peak HP about 1K later(second light) and the last light 300 RPM shy of redline.. and if you all think the power is in the top end then why could a stage 2 07 LSJ pull car's on a 2.85 pullied LSJ that was catless with a sold trans mount and custom tuned?? and stage 1 should not shift that power band that much.. no pully upgrade jus a little more agressive tune

 

hmmm nope didn't say that i just checked my posts .... i said what i have been saying the entire time to you ..... the car makes power up to its 7000 rpm rev limit with the stage kits. you claim it doesnt !!!

GM rated these cars at 205 hp @ 5600rpm which is not peak power .... a stock SS/SC or IR will make anywhere between 210-215 whp stock usually in the 6000 rpm range. GM underrated the car from the factory.

 

I dynoed on a dyno jet with gm stage 2 and made 250whp with a 2.9 pulley and weapon r race header and full exhaust.

 

No **** it makes power. Do you think I was saying that after 6500 the car shuts off?

It does not make peak power at 7k with the M62 and stock cams.

Thanks for the informative post. I needed someone with brains to help me out here! lol

I want one of these guys to go the dyno and spin their engines to 8k! Then they would make some SERIOUS hp!!!

Where?

 

So if I get what some are saying (which others seem to disagree) is that a staged cobalt only has increased power with the additoinal HP from 6500 yo 7k?

 

It does and I showed it?

Wow attacking a mustang dyno's numbers... priceless

I think you need to revise your previous postion.
