untuned 5.3 dyno numbers w/ some nitrous
Well finally got to see what my car makes on the dyno 272whp/310tq on motor and boy it woke up on the juice, 380hp/430tq. Under the nitrous pull had to let off the throttle because of a fuel leak.

Re: untuned 5.3 dyno numbers w/ some nitrous
This is useless without some engine specs posted... Is it just a stock 5.3 or what? Those are some sweet numbers though, that is for sure! How big of a shot?

It has a 04 corvette cam,springs, and a 100 shot of the NOS brand. This one guy at the shop tried to tell me that the cam i have is too big, i replied "it's not nearly big enough. I know for a fact there's more power in it."

Can you list the mods you've done to the engine?

Re: untuned 5.3 dyno numbers w/ some nitrous
The camshaft is a LS6 part # 5308 with the .555/.551 lift and 204/218 on a 117.5. Numbers may be a little off but its close. 255 fuel pump, 8.1L injectors, and LS6 valve springs. Everything else is stock, I even still have the truck intake.

Re: untuned 5.3 dyno numbers w/ some nitrous
im curious, is the 5.3 you dropped in an LM7 or L33, based on the #'s your providing im assuming an LM7, which stock has about 285hp, minus roughly 20% through the drivetrain (230ish hp) add the Ls6 cam, and your at 272hp, so it picked up 44ish hp off that cam alone?? That seems pretty impressive for a fairly inexpensive cam... but maybe its just me...
Headers/manifolds? no other mods at all?? Ive just never seeked out the actual gains from an LS6 cam swap into a 5.3, i knew it was a good upgrade but i was lazy.

Re: untuned 5.3 dyno numbers w/ some nitrous
It's a Lm7. I don't have headers, I know if tuned I could possiblely get close to 300 HP at the wheel. I don't think that Dyno was that accurate. The one guy that was doing the pull didn't run it through the entire rpm band. My car really picks up from 5000-7000 rpm. He stop the pull at 6000. I should get a Ls1 intake as well to free up more top end Going to start my turbo build next month hopefully.

Re: untuned 5.3 dyno numbers w/ some nitrous
Another video this one is a N/A pull, sorry about the horrible sounds and this guy keep talking to me while trying to video. Pretty cool dude. Anyway, the car still needs a tune bad, the car is crazy on the juice. When to the track 1/8th and the car just shut down under nitrous after about 4 secs. And i coasted to a victory of a 04 cobra. Then the it cranked right back up. I think im still flooding it out. This ever happened to anyone else?

You would be better off with stock 28/lb LS1 injectors then those HUGE injectors. And are you spraying before the Maf? I hope so.

Re: untuned 5.3 dyno numbers w/ some nitrous
Not the oil pan, had to use Fbody one and Fbody exhaust manifolds. But everything else is.I'm using a three inch hood cowl. It fits good. But a 4 would have been better. I had to file one of the humps on the alt. down a little. But it fits good now no problems and saved me money. This started as a extreme budget build to have fun in.

Re: untuned 5.3 dyno numbers w/ some nitrous
Yeah, I brought them because I started with a used turbo build. And one turbo turn out to be bad so I sold.the good one. And got nitrous but I'm going back to the turbos I got one saving for another. But I'm spraying after the maf, I have a wet shot.

Re: untuned 5.3 dyno numbers w/ some nitrous
dude please don't spray that poor engine anymore before it gets tuned. One nitrous back-fire can ruin a lot of hard work and start a nice fire

Re: untuned 5.3 dyno numbers w/ some nitrous
Actually just put the kit up for sale to fund the turbo project. NOS wet fogger system , 10lb bottle, purge system, bottle warmer, pressure gauge, and WOT/window programmable switch/ 100 hp jets and 150hp jets. For reasonable offer any interested buyers?
