Question in cam power

I have a friend that has a 2012 camaro has headers, CAI and cam. Before the cam he was making like 416rwhp and after he was making around 460rwhp. (his cam is the biggest you can go without flycutting)

My question is, is 50rwhp really good or is something wrong? Seem like thats not much power for a big cam.

whats the average gain in cams?

Hard to say really. What was his baseline power before anything was added? I just got mine back from Vengeance tonight. Gained 90 rwhp over stock. The tune has a LOT to do with it.

416 with headers and cai sounds really high but it all depends what cam u run. Do u know what the specs are and who makes it ? That gain doesn't seem right tho from 416 prior ...

He has a tune on it too. I don't know the specs it was a custom grind. He said the guy does this cam a lot.

Don't forget there are plenty of factors involved here as well. You can define a cam as "Big" a couple different ways too. He could have a ton of lift on the cam but less duration.....The tune could be very conservative.....It could be a "BIG" cam for an L99 or mabye the stock springs (not advised by the way).....Or just a big cam for the street.....or it can be a tighter dyno that reads low. Either way, 50 rwhp out of a cam isn't a bad gain.

I have a 231 / 243 in my m6 and it kind of sucks to drive with the stock gears. I love the sound of the cam and the power it makes once it gets moving so now I'm going with 3.73 gears and a supercharger. I guess what I am saying is you may consider gears with that large of a cam.

the thought has crossed my mind but want to drive it first and see how it feels.
Lethal did say it should be fine on stocks.

Was the cam degreed when installing? Most shops install dot to dot, and that may or may not be degreed correctly. Always check. Also, most use a preselected pushrod length and that is a guess as well. You can't guess on the proper preload and push rod length to achieve this, has to be the last thing measured for.

All will effect the power made from a cam swap.

A gain of 50 would be pretty good actually.

Remember a dyno is a tool used to measure so, "what he had coming in and coming off" are going to be quite relative.

Gaining 50 is about the norm for most regular/mild swaps.

You can drop a LS9 cam in, get 20/25 all day long while you could drop a G6X3 or one of our SWS II's in and see 75/80.

Tuning will make all the difference in "max effort" cams and thats where you'll see the difference of a "I only made 50" as opposed to "I hit 500 rwhp!"

Remember, those two statements above, can actually mean the same exact thing as well.

Baseline, reference, and measuring stick. That's what were talking here when we are dealing with Before and Afters.

GL and let us know if you're ever needing more help. This is what we do well.

416rwhp on a M6 car with LTs/intake/tune is about were it should be. Mine makes 411.

Yep. Totally normal numbers on a Dyno Jet, right where it should be.

The after cam numbers seem fine too. A lot depends on specs and tuning, but generally cammed LS3 cars with all the bolt ons will end up in the 460-470 range on a dyno jet.

Here's a link to a car we did showing similar numbers. Cold air intake, Kooks longtubes, underdrive pulley and custom cam. Fantastic power gains and stock driveability!

I agree, a 5th gen on the local dyno made 468hp with a 226/234 cam just a few weeks ago with bolt ons.

ya my car made 462/423 with the lg g6x3. which seems a lil low compared to some others but there were things going against me that day , 106* shop temps and about 500 miles from a oil change. but my car runs right with another car that identical to mine same cam and such but he made 478/432 on the same dyno. but our cars mph the same at the track. i mean dont get tide up in numbers a whole lot . but if u ask me 50 rwhp is a good jump for a cam.

Horsepower gains are not the whole story. A cam/tune will make your car "quicker". It moves torque into a more "useable" rpm range. Gear ratios don't add hp but will make your car quicker. If your adding mods a camshaft is one of the best bang for the bucks out there.

dyno numbers are a little tricky and there's a lot of factors in the dyno that can change your numbers. As a calibrator, im more focused on my scanner than the dyno. My scanner tells me if the calibration is on target. The dyno only tells me the effects of the changes I made.

Your if your car makes 450ish RWHP on a Dynojet, you'll be about 405ish RWHP on a mustang. Doesn't make it wrong, but the dyno is a measuring tool. After a long day of calibrating your car in the heat, lets say you make 400 RWHP. The next day you can cold start the car, get the fluids up to a safe temperature, and do a cold pull, you'll be just over 410 RWHP and change nothing. Again, the dyno numbers are less of a factor then my scanner.

You can numb the hell out of knock sensors and make higher numbers.

So,
I wouldn't say 50 RWHP from "his cam is the biggest you can go without flycutting" would be out of normal, but the 416 RWHP is a little high for bolt ons from what I see on a Dynojet.

More importantly, is the vehicle calibrated correctly and does the owner like the finished product.

Now take it to the track and see if his numbers add up.
