I am the owner of the Red Corvette with welded exhaust. I installed the headers but there was a leak so I took it to a Spanish only speaking shop. there was a miscommunication and they welded everything. sorry about the extra work 😆 🤣 but damn the final product is a beast. so happy with the car. was only expecting about 615 wheel. ended up with 647 wheel. RPM does amazing work and I got to see the dog in the office when picking up the car. huge dog. knock off ZR1 wheels are not my choice 😆 previous owner did that

car was previously tuned by nexgen auto in Glen Burnie.

Coolant SME here, coolant is actually ethyl glycol and the chemical properties make the boiling point of water higher and contains anti corrosion properties to protect the metal surfaces of motor and radiator. Now back to our regularly scheduled programming power and torque. 😂

Ls7 is king I know a guy with a ls7 motor is like a 500 something cubic once making over 700hp na he has custom made everything

[@nurburgringdreaming2221]

If talking today’s N/A yes but not historically. GM and Ford both made N/A big blocks in their production cars that were under rated but actually made way more than 505 ZL1 427 is just one example

[@midnight347]

I think he's referring to power to be had modified not what they made stock. As great as the big blocks were in factory form they didn't have 'way more than 505' even in somewhat heavier cars (alot of them aren't as heavy as you may think compared to modern cars) because the stock trap speeds just weren't high enough to have had that kind of power. About 110 mph is the fastest just about any of those big blocks ever trapped in stock form. The big block cobras trapped like 120 because they were crazy light.

[@jz28h]

Sad thing is big inch Modular’s make power but most don’t bother they just build the bottom end and boost.

I'd take a 9L V10 built by Nth Moto for NA power or TT power.

[@devintoledo4123]

Hey guys love the content keep up the great work. I have a question wanted to pick your brain on some things. Currently finished doing a stage 3 TSP heads cam With all supporting mods. The power tune is fine my issue is start up just can’t get it to have a clean start up any ideas

[@kirstenpedrick2286]

The tune.

Haha. Yes she’s right. The tune

[@omygunny4978]

So is it better to clamp or weld a cat back exhaust?

[@dennisrobinson8008]

With V-bands it doesn't matter, except V-band gives ease of removal.

[@danieljadorie829]

LS7 probably king Does anyone know if there is equivalent of the stage 4 for the Viper V10? That might be the only thing that can maybe hang NA.

[@corystansbury]

Gen IV/V Vipers are north of 800 to the tire NA these days.

[@joem1382]

fair but not fair. that's a V8 vs V10. but Viper are sick cars

[@midnight347]

@@joem1382 just like the vette has 7 liters stock and many bore and stroke them to much larger against 5 liter mustangs and vette guys wanna brag about making more na power. It's about as far as comparing the vette with the viper. I get they're v10 vs v8 but still the displacement difference between the ls7 and coyote is more than the difference in displacement against the ls7 and the newer vipers. Just throwing that out there food for thought.

@@midnight347 Its not just the LS7 that makes the Z06 that quick, the fact that its only 3000-3100lbs is a big factor.

Lsx 454 are straight trash and make no power.

[@swappedoutZ71]

@@RaceProvenMotorsports damn, first time hearing that. What gives? I thought they were supposed to be really good

[@dustinlou4695]

Perhaps... But the viper V10 is the king of boosted power.

[@Epsonblade]

There are LS setups making 4000hp. The viper is not the king. Why don't you see hundreds of them racing no prep? Everyone makes power with an LS. Not too many people can afford to make power with the lambo or the viper v10s. It will cost a dime for every dollar to make the same power on an LS setup. Shoot there's even people swapping the lambos to LS. There is a definite reason.

[@motonvipr]

@@Epsonblade Show me an LS street car running 6-second 1/4 mile full weight at 4000lbs. Nth Moto has two Vipers that can, a gen II and a gen V, still stock block for both too. There are no LS cars racing 1/2 too, they are too slow. Viper is RWD king of 1/2 racing, maybe in drag racing the LS has something, but its tough to beat 10 cylinders.

[@Epsonblade]

@@motonvipr You are talking about two development cars that have full race programs. You tell me who else can afford that. There are hundreds of 6 and 7 sec all metal LS cars doing it. We are talking about drag racing. Not rich boy fantasy 1/2 mile. There is no average Joe that can race 1/2 mile. Street cars with junkyard 5.3L gen 3 and gen 4 LS motors are everywhere. They all make 1500hp on pump gas. All due respect, and since you're a ford guy and i dont doubt you have a 3500hp viper that does it, but you are barking up the wrong tree.

[@motonvipr]

​@@Epsonblade LOL, full race programs? These are enthusiast owned Vipers. They can be street driven and does not use a billet block. So you have no LS car that is street driven, 4000lbs, stock block that can run 6, like Nth Moto cars can? I guess LS isnt all that. Also, barking up the wrong tree? Theres a dime a dozen of you LS clowns. It gets real quiet when TX2K and FL2K are on, LS guys are no where to be found.

[@Epsonblade]

@@motonvipr How many vipers do you own? You have to be worth a lot of money to own one. Then start a race program, then drive them and tune them with an entire pit crew. That is why theres only a dozen of them doing what you claim. LS is king. Your own blue oval used the design on the proclaimed Godzilla motor... The LS is the king. Vipers are far and few between. Shoot for the cost of a stock viper i could build two LS cars that run 7s in street trim on a 275. And I would do it myself, not with an entire pitcrew or a half million dollars...
