that’s really cool your tuning strategy is on point theres not many people that understand how cylinder pressure and timing relate to each other

[@boost1728]

Awesome content, format is perfect, you were made for this lol. Anyone getting into tuning or budget builds would be crazy not to subscribe

[@SquirrelTuned]

Thanks man! Be sure to share so all the other budget guys can find it!

Thanks man!

[@jamesholmes3955]

Thanks for sharing!

[@NoNameRacecars]

Great video, we’ve been running a SBE L33. Interesting to compare logs!

[@SquirrelTuned]

Thanks! And yes sir everyone has their own way of doing things!

[@TurboV8boi]

Cool to see timing that low. I'm running 19 lbs on a s480 at about 19 degrees on ethanol. I do have it pull some timing out at peak torque because I'd also like the rods to remain a straight line and not a taco.

[@minnick99]

Great job, Jack! Amazing what can be done with such a conservative tune-up. Let the turbos do the work.

[@SquirrelTuned]

Thanks man! And yes sir that is the way to go in my opinion!

[@mannyr.2756]

Wow a 4.8 stock bottom end dude keep doing what you're doing this is indeed awesome those Ford and Chrysler guys can eat their hearts out GM rules!...👍

[@SquirrelTuned]

Thanks! Check out some of the newer videos it's been much faster since. Need to get another one up it's been even faster than I've posted.

[@mikemaccracken3112]

Thank you for sharing Jack. Pretty amazing what a determine person can do on a budget. Excellent job!

[@SquirrelTuned]

Yes sir! Crazy what the little motors can do. And thanks man!

8400rpm on a stock bottom end 4.8 on lost of boost 😈 gotta love the sbe 💪🏼. Awesome job man.

[@SquirrelTuned]

Thanks man!

[@lukebradford4911]

Nice work Jack, awesome video cool to go through the logs from your pass.

[@SquirrelTuned]

Thanks man!

[@jordantrujillo293]

Thank you so much! I haven't built my 5.3 yet but have wanted to learn tuning, especially with Holley. So this is great info to know and learn.

[@SquirrelTuned]

No problem thanks for watching!

[@jordantrujillo293]

Squirrel Tuned just watched this again, do you plan on doing a video covering cylinder pressure? I keep seeing that come up and was curious to what you did, I’m aware it involves boost and timing. But otherwise clueless

[@fitzeesfabrications]

Great info. Congrats on the 1000 mark.

[@SquirrelTuned]

Thanks man!

[@TaylorRacingChannel]

Great video man keep up the hard work! Very impressive an a inspiring!

[@Gotzy392]

Just started tuning lol, fair play to you and thanks for the video, great stuff!

[@SquirrelTuned]

Thanks man!

[@billbraski2175]

Great video thanks. You definitely deserve more views.

[@alexrozier6550]

Great vid bro. Some good info here damn. This will help me keep them rods inside the block too. I will be running M1 so timing will be alitle different.

[@SquirrelTuned]

Yes sir it is more about what I am doing with the timing than the timing number itself though that can change from setup to setup etc.

[@alexrozier6550]

@@SquirrelTuned yeah i will keep up with your build so i can keep learning. I will be running ms3 gold box by the way 8 injec for now and mech fuel pump

Actually made a bowl of popcorn for this one, lol.

[@SquirrelTuned]

Best way to watch it! Kind of made it into a story anyway!

[@prestigeracingmotorsports9169]

You should have more subs solid humble dude. Keep at it can’t wait to see what you do next. I could only imagine what could be done with a built motor🤔

[@SquirrelTuned]

Thanks for the kind words man! Picked up 500+ subs in the last 30 days so it's growing! And stay tuned and we'll find out together! That's coming after the 4.8.

[@rogergm92]

Amazing combo

It's pretty cool of you to share your knowledge on here with everyone man! I dont have a very big channel but ill give you a shout on a vide soon! My question is on IAT. Besides power have you had any issues with high IAT's at all? Let me know how to get a sticker and ill trade you one from my channel. Looking forward to more content man! -Dane

[@SquirrelTuned]

Thanks man! And I've had high and low. On this 7.91 it peaked around 130. On my 7.80 it hit 190+. I'm not scared of hot air with the right fuels.

[@Burndown]

@@SquirrelTuned Looking forward to the sticker man! Looking forward to more videos.

Squirrel Tuned how much does your car weigh?

[@XxHACKERZx]

Can the valvetrain modifications you did to the 4.8 be replicated in a 5.3? Loving the content btw

[@SquirrelTuned]

Yup sure can! You will want a different cam and the longer stroke of the 5.3 will probably make it not quite want the RPM as much though.

[@iketurner1124]

Great video! How much does this cat weigh?

[@SquirrelTuned]

Thanks man and when I went the 7.91 about 3000lbs maybe just under.

[@SouthernSpeedVideos]

Hell yeah man! Subbed for sure. Gives me hope. I'm building my first turbo SBE LS and I'm (attempting) tackling all aspects. From wiring to fab to tuning. Only thing I've got limited experience but some knowledge about is the tuning. Wish me luck 🤣

[@SquirrelTuned]

Awesome thanks and good luck man! I did the same on this car other than fab. SBE stuff is fun!

[@414Chevy]

Fucking amazing!!!!!!!!

[@joeyjojojr.shabadoo915]

With more of Cleetus's failures fresh on the mind, I have to ask a few questions. OBVIOUSLY your tuning strategy works, in terms of timing and being mindful of cylinder pressure. Do you think that your ace in the hole is the short stroke combination with the 4.8L ? You haven't mentioned pushing a head gasket either, like many others in their 4" stroke 'built' motors who seem to think that they need 30deg @ 30lbs..lol. ...and are scared of anymore boost than that, yet will continue pumping in timing simply by checking the plugs physically. Because you began this tuning career with a fresh set of eyes, do you think that there are many tuners still stuck in OLD ways of thinking and infact there is room for new tactics ? or is this simply the case of a perfect storm with trying to keep the 4.8 alive and benefiting from the low TQ production in the low and mid ranges naturally ? Again, PROPS to you and your mission. I am strongly considering a 4.8 Colorado street build and applying some of your thinking, keeping it a kitty cat in the low mid ranges so as not to tear the truck apart...and where the wife might drive it, and then a monster up high when I wanted the performance.. Cheers.

[@SquirrelTuned]

The 4.8 naturally making less torque does help but the same methods work on all sizes of engines. I've got a customer with a sbe 6.0 that's within 100hp of where my 4.8 has been and I think it'll still capable of plenty more. And I think there's many ways to do things and there's not just one right way. But there are a lot of tuners that just run flat timing through the entire rpm range which I don't feel is the ideal way of doing things. But then again if you're converter only drops 500rpm on the shift and always keeps rpm high that way of tuning works just fine.

[@joeyjojojr.shabadoo915]

@@SquirrelTuned I'm a fan of big bore/short stroke/long rod especially for forced induction and big RPM. The fact that you are not crying for an LSX block as the only way forward and manage to keep head gaskets in the motor is a testament to your tuning ability and understanding of cylinder pressure and timing. I wish more people were less afraid of boost and quit trying to fix things with timing advance.

[@joeyjojojr.shabadoo915]

@@SquirrelTuned On a side note, please eventually build a 6.0L block with a full counter 4.8L crankshaft. Small cubes are far more impressive with RPM when you are not having measure your 'manhood' against the old school who constantly say "theres no replacement for displacement" because we all know that Turbos are an easy equalizer ;)

[@SquirrelTuned]

@@joeyjojojr.shabadoo915 oh I'm all about small cubes. I think my next motor will be a 5.3 more than likely. Then maybe later on a good block and do a 388 and still rev to the moon. I like the short stroke stuff a lot better. Only thing I don't like about the 6.0s is the cylinder walls seem to be a weak spot.

[@UGGdyno]

I have a turbo LS Fox, 1.35-ish 60 foot times and my oil pressure drops to about 20 PSI for the first 2 seconds or so. I saw in the data log that you didn't have that issue, mind sharing what the oil pan set up was?

[@SquirrelTuned]

I had the holley 302-1 pan, swapped to moroso 20142 though because the holley pan put the diaper too close to the flexplate. Also recommend over filling any pan you use by about a qt.

[@UGGdyno]

@@SquirrelTuned Thanks!

[@johnstonracing6715]

Are you doing any fuel/timing adjustments to #7 and #8?

[@SquirrelTuned]

No sir all cylinders the same.

[@derekwoods8199]

Baby soft timing ftw haha

[@SquirrelTuned]

Yes sir! And all the boost lol.

[@reapermech]

so with the conservative timing map that you are using , would you suggest that to someone using a sbe 5.3 ?

[@SquirrelTuned]

I wouldn't suggest copying it directly because not every setup will want the same amount of timing. However I would recommend pulling timing at lower rpm like I do.

[@reapermech]

@@SquirrelTuned exactly what i was hoping for , really appreciate you answering all of these questions

[@mike.fleming]

Do you do any remote tuning?

[@GTStuning-]

How tall was the rear tire on these passes?

[@SquirrelTuned]

28in, it is a 275 et pro radial.

[@GTStuning-]

@@SquirrelTuned Do you think a 26" tall tire with a 3.31 gear would have done similarly or maybe a 27" tall tire with a 3.42 gear? I ask as I usually use 26" and 27" tall tires on my fox and would love to know if I can make mine equivalent in that sense without going to a 28" tire. If the 26" tire hooked, would the lower numerical gearing of the 3.31 gear cause too much load for the rods? Thanks

[@SquirrelTuned]

@@GTStuning- I would have to check with a gearing calculator to see. But I see no issue in doing the same thing with a shorter tire with a little longer gear ratio. 3.42 and a 26in is pretty similar to 28in and 3.73. I actually ended up going to a 4.10 after this. Ideally you should go through the traps a few hundred rpm past peak power rpm so that is one way to pick the gear ratio. Also need to keep starting line ratio in mind though. Lot of different factors.

[@GTStuning-]

@@SquirrelTuned great to hear thank you, I appreciate all the info

[@nsboost]

What plug, heat range, and gap You running here?

[@SquirrelTuned]

At the time of this pass br7ef .022 gap. Moved to a b8efs at .018 after.

[@nsboost]

@@SquirrelTuned so I pretty well have copied what you have done tune wise. 11:1 5.3 with stock 862 heads. Custom BTR turbo cam for my combo. Btr high rpm spring kit. Forced inductions billet s485 with 96mm turbine in a 1.32t6. Ptc converter Glide 1.76 first 3.42s 28x10.5 or 275s mt pro Right around 3500lbs race weight. 5200ft altitude and DA between 10k-12k (yeah sucks). Thing runs 6.0’s in the 1/8 like a bracket car 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️. Not sure what I’m doing wrong lol. Cars heavy but should go mid 5s

[@SquirrelTuned]

@@nsboost How much boost? And what mph?

[@nsboost]

@@SquirrelTuned Quickest pass: Summit stg3 turbo cam: leaving on 14.5psi @4200rpm 18psi total boost 1.45 60ft 6.04 @ 117.5mph (shifting 7500) Fastest pass: Summit stg3 turbo cam: leaving on 14.5psi @4200rpm 26-27 total boost 1.52 60ft 6.14 @ 120mph (short shifting 7k) Put the high rpm btr springs in and the btr cam. Ran as high as 28-30psi shifting at 7800 and still haven’t broke in the 5s or been 120mph again. There’s a race at the track Saturday. I was going to give it more boost but I’m MAP limited right now (so after 27ish psi I’m out of range of the map). I thought about trying to leave with more boost at a higher rpm?

[@SquirrelTuned]

@@nsboost have you looked at a plug for a timing mark?
