This video covers our very first trip to the track with the blown SBC in the 48 Ford Coupe. As you will see I severely underestimated the torque of this Alkydigger setup race 8-71 with Enderle Bird Catcher Methanol injection. In addition, the wheelie bars are not sufficient for this power level so we will be replacing these wheelie bars over the winter with stronger and unsprung top bars.
Special thanks to Tommy Krupa at South Carolina Motorplex!
I also cover the changes we are making to correct these issues so we can try to get a full pass before the tracks close for winter.

You are an amazing teacher, There's a lot going on with the suspension, I absolutely love how you break it down I love your past videos as well, It's been very helpful trying to figure out what's going on with my own car,

[@thegoldendoggo7706]

Hey Kevin, I have no idea about suspension or racing applications but I want to get into racing. Your video explaining suspension have helped me understand alit. I just want to thank you for all the information.

[@KevinWilsonSBC]

TheGoldenDoggo thanks so much for your comments! Appreciate you taking the time to leave a comment and for your encouragement! Glad to help! Go fast, go straight! Be Safe!!

[@peterbeyl5817]

Kevin you have a real knack for tackling the subject of vehicle dynamics, kinematics and compliance and breaking them down into a real world applied subject where we non-engineers can make adjustments on our race cars that make sense to us and improve performance. You surely must have been paying attention when your Dad was speaking. It will be no time at all before you guys have that '48 nose moving towards the finish line instead of the sky. Thanks for the entertaining and informative videos. Peter from Trackside Tire, Hoosier Dealer, BIR Minnesota.

[@KevinWilsonSBC]

Peter Beyl thanks so much for your comments! Wow! Appreciate you taking the time to write your thoughts. We are going out Saturday for more testing after our changes. I am trying to capture as much time as I can with my dad for sure! Go fast, go straight! Be Safe!!

[@Moparmaga-1]

This may be the best tutorial I've ever seen

[@KevinWilsonSBC]

Korie Creson Wow, thanks so much for your comments! I appreciate you taking the time to post that comment. We will keep learning together! Go fast, go straight! Be Safe!!

[@scottnettellracing35]

Wow Kevin. Wild launch. After that first pass I'm not sure i would have been all that eager to get in and hit it that hard again. Can't wait to see if your changes give you the results you are looking for. The car looks awesome. You WILL figure it out!!!

[@KevinWilsonSBC]

Scott Nettell Racing thanks so much for your comments! It definitely got my full attention for sure! I will get a full pass out of it next time out! Thanks for your support! Go fast, go straight! Be Safe!!

[@andrewthorpe6995]

Kevin, Thank you , you just answered all the questions that i sent you the email about. you're the best

[@KevinWilsonSBC]

Andrew Thorpe you're welcome! Go fast, go straight! Be Safe!!

[@toddrochefort215]

Awesome Videos. Very excited to see how you make out. Amazing what slow mo will show you. I will definitely be getting a better camera to record my car.

[@KevinWilsonSBC]

Todd Rochefort thanks so much for your comments! Appreciate the accolades! The video is such an amazing tuning aid. Go fast, go straight! Be Safe!!

[@supercharged6771]

I'm just at the testing phase also learning about my 4 link, I'm ruining hoosier drag radial and have it set up for a bias... love the video, lots of learning going on, thanks!

[@KevinWilsonSBC]

supercharged6771 thanks so much for your comments! Keep me posted! Go fast, go straight! Be Safe!!

[@johnnienitro6812]

I'm thinking you'll be going right down Broadway next time out as well. Off the foot that is....... Guys we run with are going 4.80's on 42" long wheelie bar nostalgic rule. Great series for all to see. Thanks!

[@KevinWilsonSBC]

Johnnie Nitro thanks so much for your comments and support! I cannot wait to get it back out for sure! I think the most fun I had was seeing my dad's reaction to all this! Go fast, go straight! Be Safe!!

[@Moparmaga-1]

This will be helpful someday !

[@KevinWilsonSBC]

Korie Creson thanks so much for your comments! Hope you can learn from my videos! Capturing video is so critical to seeing what the car is doing. Having a good idea of HP and TQ is also important and I truly underestimated this one! Go fast, go straight! Be Safe!!

[@CarsandCats]

Great stuff! I know you guys will get it figured out. Do you have a build video on your SBC?

[@KevinWilsonSBC]

OneFastDuster thanks so much for your comments and encouragement! Checkout this playlist around the build of the SBC 406 we are running: kzbin.info/aero/PLK2JQ7QIgx_KUDbY3OghfnJEKjnQHCxn3 Go fast, go straight! Be Safe!!

[@marcuspace1848]

Kevin, I have a 70 Camaro 500 h.p. at the flywheel no power adders SBC at the flywheel, narrowed ford 9" 4.56 gears, Ladder bars with lower adjustment and diagonal link bar, fiber glass hood, I back halved the car, 3300 lbs with me in the seat, that's a guess. Your videos are the most informative, I have never raced but will with this car one day, I'm learning from your videos, I will buy some scales, when I get it all together, I rally want to rum a bbc 555-632 cu one day, Again I enjoy your vids. Thanks for your time.

[@KevinWilsonSBC]

Marcus Pace thanks so much for your comments and positive feedback! You will not regret buying the scales!!! Good luck on your build and shoot me some pics as you go. Go fast, go straight! Be Safe!!

[@pmreng]

The rear tyre was heavily planted to the track way too much and the front extension was too great. The changes will definitely get you down the track Can't wait to see the result of your changes Thanks for sharing

[@KevinWilsonSBC]

pmreng thanks so much for your comments! We will find out pretty soon!!! Go fast, go straight! Be Safe!!

[@mikebalzer9671]

Hi Kevin loved your videos. Just calculated our AS and IC on our 71 Chevelle and found out our AS is at 166% @ 43.5 inches. Our best 60 is 1.43 but normally run 1.47 on decent track prep and condition days. When the weather is HOT and the track is greasy we have a hard time being consistent. I did calculations on lowering our rear control arms to 2" and that would put the AS @ 126% with the IC 51.25". We run a 29x9 Hoosier slick with 12lbs and we run a N/A 406 on trans brake leaving at 5000. We just ordered the relocation brackets and hopefully, this will help with being more consistent on hot days. What is your opinion on the relocation brackets and trying to lower the AS number and extend the IC number. Also to maybe help you could you use more preload on the right side of your anti-roll bar to help keep it straighter during launching. Just my 2 cents for what its worth. Keep T&T and be safe Mike

[@KevinWilsonSBC]

mike balzer thanks so much for your comments and info on the Chevelle! We have had success with extending the IC to help with weight transfer and not shocking the tire too hard on initial hit. Rear shocks with proper valving will be key to help control the car for sure. A 2" move is a big move but the real deal is testing. Do you have any good video of your car leaving the line so you can see what is happening with the slick? Thanks for the info on the rear ARB for the 48. I will definitely be extending the right rear side a tad more to help not let the chassis dip over the right rear slick. Go fast, go straight! Be Safe!!

[@lifestream4191]

Very interesting. I'm particularly interested in the front suspension and how that changes the looks on launch. I didn't remember it being a 3 speed, I wonder how it would act launching in 2nd... hmmm.

[@KevinWilsonSBC]

Life Stream thanks so much for your comments! I will be providing more updates as we continue to test. I actually thought about hitting it in 2nd gear, but didn't do it. Go fast, go straight! Be Safe!!

[@dariushill4217]

Great information! Also what editing software are you using?

[@KevinWilsonSBC]

Darius Hill thanks so much for your comments! I use Final Cut Pro. Go fast, go straight! Be Safe!!

[@abadwillys]

i would put the front end limiter on and def longer wheelie bars, Love me some Blown Alky Power!! what size slick is that?

[@KevinWilsonSBC]

B.H. H thanks so much for your comments! They are 32 x 14 x 15 Mickey Thompson Slicks. Go fast, go straight! Be Safe!!

[@Jonesmoto]

Hi Kevin, what camera are you using? Thanks

[@KevinWilsonSBC]

Jonesmoto thanks so much for your question! It is a GoPro 9 filming at 1080P 60 FPS in Linear lenses mode. Wish I would have went 120 FPS. Go fast, go straight! Be Safe!!

[@Jvcomet]

So with the anti-squat at 100% what length and height are you shooting for? Thanks.

[@KevinWilsonSBC]

VXM thanks so much for your question! Not sure if you are asking about the 48 Ford or in general? Go fast, go straight! Be Safe!!

[@Jvcomet]

@@KevinWilsonSBC both. Thanks.

[@dirtysouthstreetcars9007]

You might want to try long and high on the anti-squat to slow down the hit.

[@KevinWilsonSBC]

Dirty South STREETCARS thanks so much for your comments! Definitely making another 4 link change so stay tuned. Go fast, go straight! Be Safe!!

[@martinuresti3892]

One thing that helps is change pinion angle. Kill the wheel stand. Only make changes one at a time. Test as much as You can. 👍

[@KevinWilsonSBC]

Martin Uresti thanks so much for your comments! Go fast, go straight! Be Safe!!

[@mback12000]

No disrespect but this is absolutely not true. Pinion angle change by itself has nothing to to with wheelstand unless you changed the pinion angle by also moving other suspension geometry.

[@Disablednoob]

Man i could use your help with this car im trying to help go down the street. Im just now learning this stuff because the guys that are making all the adjustments on the car, well i dont think they know what they are doing

[@KevinWilsonSBC]

RockinGbody _ thanks so much for your comments! I love drag racing suspension challenges. I just wish I had more time to help everyone who writes in. Are you close to Charleston, SC? Go fast, go straight! Be Safe!!

[@mr.know_it_all]

I’m in the same position. Hitting the tire too hard and not enough air pressure. Add air pressure, spins tires. What I have gathered is this. The more anti squat you have the more shock (rebound/compression) you need but, if you pedal it you will have less chances of recovering the tire. The less anti squat (100-105) the less shock you need, the more neutral the suspension and now the front end is how to control weight transfer. More bite, less front end travel and tighter front rebound. I hate suspension 🤦🏻‍♂️

[@KevinWilsonSBC]

It’s not a Nova thanks so much for your comments and observations! I have made some changes andn will be going out Saturday for more testing and video. Stay tuned and let's see if my changes improve our situation. I am definitely closer to the neutral line, slowed down the front end a bunch and removed the springs from the wheelie bars. Go fast, go straight! Be Safe!!

[@ronlemon640]

What spring rate do you have up front? Thanks n how tall are they

[@KevinWilsonSBC]

Ron Lemon thanks so much for your question! These are 400lb springs up front and 10" free length. Go fast, go straight! Be Safe!!

[@hermanndouglas422]

How did you determine rear compression was to soft?

[@KevinWilsonSBC]

Hermann Douglas thanks so much for your comments! It allowed way too much load to transfer over the sidewalls. By tightening compression I slowed down that load and actually introduced a tad of cupping on the contact patch. Go fast, go straight! Be Safe!!

[@keysautorepair6038]

He must work out dang.

[@KevinWilsonSBC]

Camaro Drag Racing Second Generation thanks so much for your comments! I am fat! Need to get back on the weights though. Go fast, go straight! Be Safe!!
