Low dyno #? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Nate2SS · 10-27-2021, 08:47 AM

I recently dynoed on a mobile Dynojet that was hosted over this weekend. The car put down 426 RWHP, I feel that this is a little low given the mods I have on the car. The car was street tuned from a reputable shop. Not really complaining about the horsepower just did not know if something was up with the car.

Without knowing your mods or the year make and model it's tough to comment. Sounds high for a V6 though.

Auto? Cammed and bolt ons usually make 440-460. More if you have a ported manifold and grind of the cam.
Plus every dyno is different and weather plays a huge role too.

Take it to the 1/4 mile. that gives you real numbers. Dyno is just a tool with huge variables.

Bingo, we have a winner!

That is 50hp over a stock LS3. A little on the low side for cam and headers, but not unheard of.

Can't be too broken if it made that number with your mods. You can always send your oil in for analysis if you are really concerned.

Noted. I will report back when I can get to the drag strip then.

Yea these engines and the different cam setups people are running can make all kinds of different numbers depending on the dyno and how it is setup. Your numbers are not that far off of what most are making with a cam of that spec. Like stated above they can be anywhere from 430-460, and also depending on weather an barometric pressure. Take that baby to the 1/4 mile and do your best and see how she preforms, that will be your "dyno" number. I too was once hung up on a number, but got past that as it is only a tool to dial the car in to run correctly and reliably. Good luck and have fun!!

This is good advice, thank you, I can't say the low dyno number didn't hurt

. I'm hoping the 1/4 will give me better results.

Sounds about right if your Spectre CAI did this…

It is low for a cammed car. That should be at least 450 if not closer to 475. You might have an unfriendly dyno. Like others said, the real important thing is your E.T. at the end of the track.

One thing I have come across here a few times: How does the butt dyno feel.

I have noticed on hot, humid days my car is just not there. On a colder dense air day it gets downright violent.
