Lesson learned. Skip the intake

I'd call that decent bang for your buck.

I did hear the swoosh when I first got it, but after the polyurethane motor mounts that's definitely gone lol. When you already have a higher power setup compared to the stock, wouldn't you expect more? Kind of a proportional gain?

I will give one prop to the adm intake. The flat box gives a nice place to put my tools on while I'm working in the engine bay haha. I hope I can say that it gave me all 9hp but idk

You're right I should've put in 3 so I could have gotten 3 times the benefit. It would've cost the same too!

Thanks for this. I do plan on sticking with the npp. I guess the only thing left are the heads. Which I'm dreading... Gonna be harder than the cam swap

I cant speak for what kind of gains or loss for temp but I know my boat the temp makes a big difference. I have 2 225 HP engines and when its 90 out I can only turn 5200 RPM at 70 degrees I can do 5400 and 50 degrees or below I can spin 5600. same amount of fuel and with the same degree of fouling on the bottom. The temp will make a difference and since you were 20 degrees hotter that might account for some loss.

I wouldn't be concerned with rwhp. Go see what it does at the track

I will be going either friday or saturday. Would be cool to see a tenth or two down but IDK.

As for the temp. I want to believe but ... SAE correction

[Pro Stock John]

Once you do all the big mods, and I'd put cam on that list, all the other stuff will give little gains.

I've got PTB by Bo, heads ported by Bo, an underdrive, rod modded intake... and I am fortunate to have trapped 125.5 on pump gas last year. I wouldn't take a single part off the car I need every bit of power I can get to run quicker this year.

[Bo White]

Agreed. Its a combo that works more so an individual part.

The correction factor should have changed with different weather conditions between pulls by my thinking. But hey your just one of ton of guys who used to do intakes and then complain they did not gain much. That's the reason MSD tried, that's the reason the Vararam VRX is still wondered about....as in when the hell? And that's the reason the Fast sells with even its gains better on a larger displacement radically cammed engine.

Someday I may have to settle for FAST but hey....at least I know the last place to look for performance per $.

This run I put in the adm intake, a ported TB and NOT a fast intake, but a rod modded intake.

The adm intake claims 10 and costs 400+ the scoop and water bottle.

The ported TB costs 150-200..i didn't expect anything tbh.

And the rod modded intake manifold claims 10-15 and costs 250.

Not that I expected anything, but I thought going from the stock motor mounts to polyurethane, would've net something due to the claimed "deflection" too.

So now you can see where something is missing. My main draw back from this is that if you do things that really matter, like the heads, headers and a cam swap, that's where you're gonna get real numbers and not some negligible junk. Overall I spent roughly 900 bucks for 9hp and 1lost torque (this doesn't include the cost of the mounts) .

Also, by going with the adm intake and scoop, I realized after the fact, that I now have to find a solution if I ever want brake ducts because the scoop is in the way.

Getting the heads worked on would've cost more, yes, but would've been way more beneficial.

I do have some good news.

Within a month or two I will be making a trip back to the tuner and will be isolating some of these parts, including the exhaust for testing. I suspect one item isn't doing what it claims and this isolation should show what.

What cam are you running right now?

The correction went from .99 to 1.02... However I have no idea wht that means

Thanks to the OP for sharing his experiences and dyno results. ....I didn't do a PTB or intake on my build, but I did spend extra on the valve train and heads/converter/17" Welds/drs.

Always have a specific goal and game plan to get there. For instance, I want to smoke Hellcats and get into the 10s, undecided on the forged crank stroke, but realize that an ECS Paxton w/methanol will more than likely get me there with a motor that can spin with high shift points. I realize that Hellcats come on strong on the top end, choosing the right ls3 components, including suspension, will take the Hellcat's advantage away.

Anyway, wish everyone the best with their builds.

[WHAMMO]

What do you trap OP?

I would be more than happy to have a modded manifold intake(GPI or Rick Crawford), they are worth the cash. The only thing better is a MSD or EFI style if spinning to 7k+ all the time.

Ported TB are way too expensive IMO. New Era offers TB porting for 75$ IIRC.

Head swap is easier than cam swap.
