My auto car on a mustang with just ported blower made almost 495. And your crank calculations are way off.

Thats the 650hp package from Lingenfelter. Dont know how it could be more hp than that. Except for the extra im getting from the water/meth and headers and CAI. I also dont know how it could be any less than that with that kit and all the other mods. Which puts my crank #s right where they should be. Impossible to be off on the crank calcs, verified them with my other bone stock ZL1.

650 lingenfelter package is no headers and just the upper pulley. And jyst a intske tube not the entire box which is a big deal. Your car should EASILY be making mud to upper 560-80 and need injectors without a dought with those mods.. I know. Im doing them right now in the same car.

My 6M dyno'd 496rwhp,480rwtq so your about right on, it was at 1200km only added k&n air filter at that time

Here is what i did. all except for port and polish of the blower. Already had Araid. This is what the kit has. Plus i also did headers and cats and exhaust before this kit, because with all the extra boost we were afraid we would melt our stock cats, which i believe someone else did on their ZL1. Ps we did the injectors, did you read my build thread.

Not sure how you came up with 430 for stock RWHP, most everyone here stock are running around 500.

His math is waaaaay off, but OP is convinced he is right. Whatcha gonna do

536rwhp is not, I repeat not, 744 crank HP

[The Baron]

Well this is the fun over the internet. I wish you the best

Only way to "melt" cats is bad tune. My wifes daily ctsv is full stock exhaust at 15+ pounds .. 42000 miles.

Enjoy your car. Numbers the dyno seem very low.

So what would you figure the 650hp kit from lingenfelter gave me. And then figure what you would give me and tell me what you think it is because i guess checking the math and conversion against my other ZL1 is not good enough. But what does the LPE 650hp kit give me at the crank. And what do the other mods give me at the crank. I dont know. But i called the shop and asked him again and we went over it and that is what it is 744. But if you know more tell me what it is, should be easy. 650+meth+headers+Araid+tune=fWHP, you tell me what it is. And i suppose the 448rwhp on the dyno sheet below is not, I repeat not 580 crank hp is it. But it definitely is my stock dyno #. And the stock hp # on the dyno that gave me 536hp was 418hp, i have the slip at my shop.

Here is my dyno stock sheet it was a mustang dyno. It shows 448. sorry, not 430. but not 500, not even the dynojets are giving 500#s. But the # depends on the dyno used to get the number at the wheel. But they all give you the conversion to get you the flywheel # which will always come up to the same # which is why i gave the fwhp, and probably why the manufacturer gives you the fwhp, also its a higher number . I don't know why but this seem to get explained in almost every thread about dynos
