416 LS3 Engine Dyno Results - Insane NA Power!! Ep. 11

[@chrisciolekracing6945]

I miss Jim Kuntz! He left the company to his employees when he finally passed. Jim and his employees are the best in the industry. I'm truly grateful that Jim invited me into his house and family many years ago. He has done wonders for the SBF world but a great asset to the racing world! Kayla, Your in good hands!

[@KaylaRundle]

I wish I had the opportunity to meet him. He was mentioned a ton while I was at Kuntz & GPI. His legacy lives on! I’m very lucky to be working with GPI on this project. Thank you for the kind comment!!

[@timbo2ssrs]

my daughter is 9yrs old. She loves my camaro, well "her" camaro as she says. I showed her your videos and she is now wanting to do something to our white 2ss named Betsy. Your a role model to her now

[@LD100]

It's awesome that you have access to all these nice facilities with knowledgeable people to help you out.

[@bighouse1695]

What a dream come true to build your own engine in such a great facility with all those professional people willing to help and share their knowledge. These videos have been amazing. Thanks for showing us all of these Kayla!

[@spdcrzy]

Pulling the throttle cable on an actual engine itself really gives you a true appreciation for JUST how much power you truly have at your disposal. And it makes you respect it.

[@Tracklyfe_T]

you took your car to another level sis. Easily one of the best camaro builds I have ever seen. The fact u kept it N/A too and didn't go the easy way. all the respect in the world. !!

Good for you girl. 740 hp naturally aspirated is beyond what I thought. Unbelievable build Kayla. Super proud of you. I could tell you were a nervous wreck at first but the look on your face when it started making power was well worth it. You go girl

I don't know who this young woman is, but as an old guy engine builder, I thought "how cute!" and started watching her! Sorry for my ageism but I never considered she could be THE greatest race driver of all time! Then, although I still think she is a cute young girl I started seeing all the tech and money she is spending on this car and engine! For most of us this is just a dream to build such beautiful/powerful engines! GREAT WORK! I LOVE watching Kayla's exploits! keep up the greatwork!

[@dennisrobinson8008]

Torque numbers are high with the 631.6@5000 rpm and the 629.3 @ 5300 shows an efficient combo, nice power with the 732.2@6900. Nice combo. Have you made any updates?

[@C6Z_Bob]

Badass! I was eyeing the GPI MAX 2.0 package for a while, LS7 ports make waaaay better power than LS3 ports. It's really cool to see someone put it on the a 416, I've been wondering how it would do ever since Andrew @ GPI had mentioned that this package was in the works on the Camaro5 forums a few months ago.

[@dennisrobinson8008]

LS7's are awesome but LS3's are no slouch. On the ford windsor side you have to go to serious aftermarket heads to be in the ball park of LS3 and LS7 heads. I'd imagine it's the same on the SBC side too.

[@DaddychiLL6]

[@AB-80X]

I would love to see more girls get into this and have some fun on both the drag strips and circuit tracks with stuff they built themselves. Videos like these shows other girls out there that you don't have to be a butch crew cut tomboy to have fun with cars and engines. Awesome Kayla, I hope you get many, many hours and miles of fun with the engine you built yourself. 740 is a stout number, no matter what engine it is. Love the enthusiasm too.

[@gen2-x364]

Like your new engine build. N/A is the way to go...simple less complicated..... Soooo......640--650ish to the wheels.....that's very respectable for a street car.

[@josephsolomon8623]

Somewhere between 10 seconds and 11 second quarter mile that's my prediction she's a work of art Kayla you're going to have so much fun with her can't wait to see the quarter mile

9's

Could go 9’s with the right gears and suspension upgrades. Be interesting to see what the weight of the car is with driver and mile per hour will tell us what the real Horsepower is.

Hello What would you say to me if you were about to leave and saw that i had glued my face to the exhaust pipe of your car would you ask me to move or what??

[@natelsx]

I wish they still made that intake for the ls3 heads. Those LS7 style heads and intake make good power and are a great combination.

[@KaylaRundle]

I do too. I was looking at it for a while for my last block because it’s hard to find plastic Intake Manifolds (no heat soak issues being in AZ). The heads in this Heads and cam package is where all the power comes from. I was so impressed!

[@ssoffshore5111]

They don't because the factory LS3 intake is hard to significantly improve upon, which is not the case for the LS7.

[@charlespinson6693]

Great Work …!

[@lexomotorsports]

[@robertwest3093]

I wish every young lady was just-like-YOU!! This right here is my favorite thing to do of all time. 😁 And it doesn't get any better than having your engine at Kuntz&Co.!

[@KaylaRundle]

I appreciate that. Building engines aren’t for every girl but I love sharing the passion with the pros that do it everyday. Very lucky for this experience.

[@DG38594]

He is dead on with timing in that motor. More timing doesn't always make more power. You have to time it according to fuel, rpm range etc. You're making good power for what you have. 10 second car easy.

[@KaylaRundle]

All of the guys at GPI are extremely knowledgeable and I was very lucky to be there along the process and soak up all the info. It’s awesome to show off their process to you guys and it shows that they aren’t afraid to hide what they do and how trusting they can be for future builds! I’m excited to take her the track!

[@KaylaRundle]

Yeah the estimated number is around 620rwhp. I’m still on stock SS Gears and it’s built for Road Course so we aren’t trying to maximize the power. Goal is anything over 600rwhp!

Kayla I have just found your channel and I'm only a couple minutes into the video. I've noticed you have forward pelvic tilt Girls think it's a pooch in their stomach, but really it's just your pelvis tilted forward poking out If left untreated this will cause back pain later in life it's very simple to fix Do ab workouts and glute workouts and when those muscles are both tight it will rotate the pelvis back to where it belongs This will fix any back issues you have as well as make your tummy look super flat 416 * 6,500 / 3456 / 733 = 1.067 CFM per HP What compression are you running this motor? The average hot rod motor moves 1.35 CFM to make a horsepower when you get into supercar territory it's like 1.18 Full on race cars are 1.00 How are you so close to a full-on race car with how much power per CFM your motor is making? Are you either running really high compression, is it may be running methanol? It is very rare to see a motor moving that little amount of air to make one horsepower

[@KaylaRundle]

I am running on 11.8:1 Compression. On Pump E & 91. We didn’t want to push compression too much since I needed to be able to run on 91 since it’s a street car as much as a road course build.

What a doll. More women should be this way. Nothing like a good ole hotrod gal.

Sadly soon all combustion cars and trucks including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Car washs will be forbidden too because they are climate killers, now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime.!!! (BABVVEN & TEBBVEN & BEFVO laws)!!!!!!!!!!
