GTHO Cammed GT Dyno comparison - Stock Cams vs Big Cams.

We take the GT to Scotts Rods in Yamanto for a before and after cams test. After a quick road tune (Still being refined*), we were ready for some power pulls. Now to the track to get a timeslip and see if the dyno figures transfer over to the real world. I feel like that 11sec quarter mile is closer than ever!
I really enjoyed making this video, big thanks to Scott and the team from Scott's Rods, go check him out on Facebook, he does custom Exhausts and Tuning!

@@GapSauceKZbin Maybe something is wrong with the dyno? Since if the dyno is saying 250rwkw and it's keeping up with 300+rwkw cars it does suggest the dyno isn't working right. What about wheel slip on the dyno? that will affect it as well in a big way.

@@NoOne56488 Wheel slip and wheel weight will affect the reading, some dyno's have the roller speed calibrated higher/lower than others.

@@GapSauceKZbin hey not sure what size wheel would fit over the rear brakes on one of those cars but a 15x10 wheel with a Mickey Thompson ET Drag 26x10x15S. S for stiff side wall since it’s a heavy stick car, if you can tighten the rear shocks to keep it from bouncing after it loads the tires (that may be more of a solid axle thing, IRS cars like to squat a bunch) I’m sure it could pull 60s at least in the 1.6s if not 1.5s

@@ekracing2138 Yeah I'll need to go down a size on the brakes to fit the 15s on the rear but perhaps a pro radial if not the ET drag? I have adjustable shocks but I need taller springs as on launch the tyres contacts the guard and kills my travel. The bounce is what got me wheel hop and killed my diff but the new shocks seem to have sorted that. Thanks mate, a 1.6 would see me getting near mid 11's I think. Shame race weight is 4100+ 😅 I need to launch like yours!

[@ekracing2138]

@@GapSauceKZbin I personally have not had good luck with radials on stick shift cars. The radials will prob give a little mph on the top end with the more stable/stiff sidewall but they will not tolerate the hit at the starting line that a bias ply slick will. Not to say you can’t run fast on a radial with a stick car but the launch technique is much more of a clutch slip than a high rpm dump if you will. My car has gone a best of 1.44 60ft, I believe it has more in it. Suspension is no where near perfect. But it’s also a pretty light car (relatively speaking) and 4.30 rear gears. Good luck with it!!

YES! 👍 Edit: most people even back when I was doing my old car back in 2004 - 2005 worried way too much about dyno read outs and peak power and not enough about the other 3 million things that influence a cars ability to go fast. Average torque, tyres, ratios etc etc all didn't matter really just being able to say "I have X amount of rwkw" was the important thing too them. My VX SS with VCM No.7 only made 290rwkw but it smoked a mates VZ Maloo with 320rwkw because the rest of his car was factory mine wasn't.

[@GapSauceYoutube]

That's right mate, its all in the setup! Vx was nice and light too, excellent platform.

[@marklowe7431]

Hey big guy, have you ever run the beast on another dyno to see if there is a difference. There's zero chance that GT is making less than 300 at the wheels. Diff gears skew? Tq went up.....

[@GapSauceYoutube]

Yes, it made 311rwkw. I think there are some lofty dynos around. I'm trapping 8mph more than another 340rwkw 5.4 with 4.11s that a mate of mine owns. Hopefully new engine should make 30-40rwkw more.

[@DrinkinDaJuice]

My BF GT is making 434rwkw but that's because I have 13psi of supercharged boost and water/meth kit on it, plus internal upgrades and the usual exhaust and other ancillary bits. It's interesting to see what these Boss V8s can do, as they were never around for long enough to get much development going, but they seem to have a lot of untapped potential in them that people are only now starting to figure out. We found that a more standard cam profile was better for boost as it maintains the lower end and midrange torque before boost starts to come in at 2800rpm and then it doesn't need a lot of cam, as it's on boost and timing to make the power by 6300rpm. My big downfall was intake air temps becoming brutally hot after about 4 pulls. I'm still early days on sorting out the water/meth system in hopes it helps somewhat.

[@GapSauceYoutube]

Awesome mate, that's a nice amount of power. Which charger do you have? The good thing about boost is you can have a quick street car that doesn't need to rev to the moon hey! 🙂

Really solid gains there mate. Dyno figures are funny things really, all you can do is compare back to back figures of your own Car and look at the gains and losses like you have. I've seen some huge numbers on dyno's from Cars that don't deliver on the road and also the exact opposite result. I remember at a Tickford club dyno day I was at, back when the BA's were first released, a bog stock BA XR8 auto ran 211rwkw, the same Car in a manual running 216rwkw, a TS50 5.6 Manual making 203rwkw, a stock auto BA XR6T making 185rwkw and just for a comparison, the dyno operators mate's LS1 manual VT Ute with extractors/cats/exhaust and tune making 190rwkw.. These were on a dyno dynamics dyno, same day, same conditions. 2 years later a BA GTP Manual made 269rwkw on the same dyno with headers/cats/exhaust/airbox mods and tune. Obviously a way less stingy dyno than the one you're using and without the humidity you were facing here. I reckon the ol' bird will fair rip with what it's making now at your track days, it's such a great/flat power curve that hangs on to 7500rpm.

@@GapSauceKZbin if you can get the 60 down it'll do it. That mph is already good for 11's if was a zf! .1 in the 60 is .3 over the strip .

[@michelledrent5400]

In my opinion, may I suggest trying a "road launch" for the drag strip. Hold 2500 and slip the clutch. Once clutch is out quickly roll into the gas. This gives a gentle weight transfer and as the torque is low in this area, the tyres have greater chance of grip. It should also be kinder on the driveline, too. I race a FWD Levin, no where near the power or class, but being FWD the struggle for traction is real. I predict the 60 foot time to be a little lower, maybe 1.8sec, but top end power is all in the MPH at the finish. Expect to nudge 118 in the traps @ 11.9sec.

[@GapSauceYoutube]

@@michelledrent5400 Thanks Michelle, generally that's how I have to launch it. I'm going to try and tighten the handbrake up and use it to prepaid the suspension for a nicer hit. 118 is huge, I don't think any auto or manual bar bluepowers drag car has gone 117+ I'd be wrapped with a 115 honestly, the conditions won't be thst great tomorrow arv.

Mainline dyno’s always seem conservative. I remember when they tested the GT-F 351 vs GTS LSA on a mainline then they tested them again same day on a calibrated AWD dyno, while the scaling was similar both cars made more everything on the calibrated dyno. (Yes i know, no one dyno reads the same) *GT sounded TOUGH!!!!*

[@GapSauceYoutube]

Yeah different roller speed calibration can give big swings in results. I don't think there would be much in it between a stock GTF and mine. I'm well ahead of any stock 335s now down the quarter and they make 330rwkw give or take a few. I've got a dyno comp in July, so I guess we shall find out then 🙂

[@marklowe7431]

What a total load of bullshit you can't make power with a boss. Who are these stupid people? If you had an 5.4l LS making over 500hp it would be a monster. I must admit I was expecting 330kw at the wheels. Is this diff ratios? What doesn't make sense is with stock cams you in some ways embarrassed numerous other cars. Given it's making more juice now I can only think those numbers are somehow not showing a calibrated result. It would be interesting to see that running on an engine dyno. 20 bucks says it will show a much bigger number. I don't for a minute believe it's making less than 300kw

[@GapSauceYoutube]

The amount of times I've heard that boss engines don't make power from cam now.. I believe it's because the most common herrods and gtp's tend to be aimed at improving midrange and don't gain huge numbers in the big end. I'm making 103rwhp more than the last BA GT with bolt ons and a tune on that dyno, so make of that what you will I guess 🙂

[@GapSauceYoutube]

Peak power at 7400+ shows that its moving alot of air now. More than the usual 280rwkw peaking at 6200 on stock cams 😉

[@marklowe7431]

@@GapSauceKZbin 100% agree. The other guys that are making the midrange makes sense for them driven everyday too. They would be super nice in the speed range on road. At the end of the day cyl pressure x rpm x cap = outcome. Some think the brand changes physics. What you've done is killer. You've also proven how tough stock bottoms are. Can't wait to see you roll race again, I think you're going to surprise a lot of people.

[@marklowe7431]

@@GapSauceKZbin Agree, I'm not sure what it would be but I don't think the numbers add up. Have you done cyl leak down etc?

BTW, don't mean to piss in your pocket but your no bullshit honesty is rare.
