the first person to get an Edelbrock SC on a 6.2!

[bass mechanic]

My prediction is that it would be in the 13 sec range, considering it runs 14.5 stock. But hey, I'm just going off what EB told me. I agree with flywheel hp is pretty meaningless. But here is my prediction. Based on the stingray with the e force 600/625 flywheel then work the calculation backwards that puts a vette around 580 to the wheels. Now having said that the truck version actually makes more tq at 460 than the vette and less hp which tells be it's a matter of a different cam between the 2 engines. So if anything I would expect to see over 600 lbs of torque at the flywheel. I think the final numbers will be very close to 500 hp and over 500 tq at the wheels.

Without a base line wheel figure it's hard to say but as I understand it every 10 hp is roughly .1 sec in the 1/4 that means with 100 hp at the wheel it's a 13.5 sec 1/4.

I know a guy from this and another forum who did headers and a tune on a 6.2 Denali that improved his 1/4 time from 100 to 107mph and dropped .25 sec after just a tune. This would imply a near 50 whp gain with a tune! That's impressive to me,

Certainly a blower can do better

No, I said with the heavier drivetrain of the trucks 480 or so should be doable, given the cammed Vettes are already in the 520 range. Give the aftermarket some time for the parts to begin trickling down and you’ll see. And that’s rear wheel—few of us pull our engines to dyno them at the flywheel so estimated flywheel numbers are pretty meaningless.

 

 

 

Wow. So let me get this straight—you’re going back to your original prediction? That even with a blower, the 6.2 will be lucky to crack 400 at the wheels? You realize that cammed 5.3’s are already cracking 400 and running 12’s (with no boost at all)?

 

Yes, I've seen enough evidence. I've seen how many dyno graphs now, all around 340 at the wheel. Not a CHANCE ur pickin up another 100 at the wheel, let alone 160. Do you know how many guys I've raced with bolted/cammed silvy's? Crew cabs are still mid to high 13 second turds. The new 6.2's are makin 340 to the pavement (uncorrected) with a tune. Look at the facts buddy, stock they are a 14 second turd. You honestly think a cam will cut 1.0-1.4 in the 1/4 mile??? You're friggin high if you think so.

 

Again, there are cammed 5.3 trucks running in the 12's already, without even having all the bolt-ons yet. Just wait a year or so for more to become available. That's the much smaller, lower compression 5.3. You really just don't know what you're talking about regarding these engines.

Jon I see you're still reachin for that rainbow eh buddy? Obviously I'm talking about a crew cab 4x4 since you're bringing up old threads and that's what were talkin about in this one.

 

Show me a time slip of a 5700 pound truck running into the the 12's with a cam only and I'll believe your ridiculous claims.

 

No you're right jon, I know nothing I'm just young and stupid.

@ The weight of these trucks. A mid 13 second pass is not even 450 at the wheel. Even a 12.9 isn't 500hp. Ain't no way blower only or cam only is gettin you a 12, if it does I'll choke on my words.

 

I'm stickin by what I said.

[KARNUT]

Im a third owner of a 92 Extended cab Chevy truck I bought on Ebay. The first owner put a Whipple on it new with every thing there was to offer back then. He did just a shift kit and a stall in the trans 373 factory gear. He put 80k miles on it and sold it to his buddy. The next owner rebuilt the engine at 80k kept it ten years and I got it. Just before I got it the trans got rebuilt at 100K. Its set at 10 lbs boost. It been to the track a few times a daily driver a few long trips, I drove it every day for two years till I bought my new GMC. Now I drive it just for fun. I not going even say what times it ran don't want to here that noise. The point here is it will be fast as hell last a good while, the fun of knowing you can kick just about any ones ass on the road is gear heads dream. And the best part is the price is right!

i agree! and the ONLY thing thats good about living at high altitude is that if your the guy who has the blower, and essentially your getting the same performance everyone else has to move to sea level to get. it gives you a significant advantage over everyone else! unless you have an electric car!

there are a couple i know who have a tesla and those aren't affected at all by altitude. in fact probably run better here because there is less wind resistance up here.

I'm stickin by what I said.

i do not believe anywhere in this or any post did i mention anything about a 12.9 i said ill be running mid 13's and i am sticking to that assumption! as i said STOCK crew cab denali ran a 14.5 @ 100 with a 0-60 of 6.0 flat!

also my truck is a D cab, i don't know if it weighs significantly less or not

only need about 50-60 hp at the wheel to get into the 13's

also, the above times were recorded in 2wd and spinning the tires a good amount. i guarantee you if i were to take it to the track and put it in 4x4 mode i could easily shave .5 sec just in the launch!

look at it this way...

a totally stock toyota tundra with only 391 hp and i think 401 tq runs a 1/4 in like 14.75 i don't know the weight but assume it is similar to a sierra. with a SC the same truck runs low 13's all day long! I've even seen some in the 12's with some modifications. so you can't tell me my prediction of 13.5 is not realistic 12.9 i seriously doubt! but i never made that prediction so i don't know why you posted it.

 

but you know what? I'm not doing this to win any drag races! I'm not trying to with the "who has the biggest cock contest" either!

 

all i really care about is i get more power, similar fuel economy and nothing breaks and i don't need to use my warranty.

beyond that, i am told the new blower will be very quiet, so much that with the hood closed i should not even hear it under boost which is fine with me.

to be honest, if i lives where most of you do where you actually have AIR i most likely wouldn't even bother! you guys don't know how good you have it living down there. when i go dirt biking in grand junction i have to climb over 3 different passes, some of which are over 12,000 feet. the ability to bring the sea level manifold pressure with me makes a huge difference up here especially if you tow anything heavy.

[dodgehemi0]

I am so jealous of this guy why can't I get deals like this. Ahhhhhh hope it is awesome take lots of pics when you get it. Can you get them to take pics of the install?

You never said 12.9 You said 500hp, which is a 13 flat at that weight. Then you said you should be able to bust a 13.5, which is around mid 400's to the wheel.

 

I'm not in it for a debate, it's just common sense man. I'm still anxious to see a time slip settle this once and for all with Jon lol.

 

Man if they say that trans can hold why not pulley down a little [emoji48][emoji48]

they told me they will be taking a lot of pics because they will be putting together a installation manual as they go. they said the physical install will take about a week because of this process, then another 2 weeks to tune. they said best case scenario is 2.5 weeks if no fuel upgrades and no additional install brackets, hoses or other special parts are needed. they have already done the 5.3 so in theory everything should for the most part bolt right up as both engines are fairly similar in design as i understand it.

you know i almost walked away from this deal just because initially i wasn't all that serious about doing it for any price. I've modded several trucks i have had and finally i had found enough power to make me happy in stock trim. i happen to like the V 4 mode and when i drive i am always looking for better MPG. loved the idea of keeping the factory warranty and everything.

but i consulted with several of my friends, even called the dealer to ask how this would affect my resale value. also talked to a local tuner and they all told me i would be a moron to walk away from a chance like this.

 

now you guys are going to laugh at this, my truck is LEASED but i had every intention of buying out the lease before it's up anyway when i got it. i only leased because i can write off the payment on my taxes being self employed and i get a lower payment. i buy out the lease at the end and if i want to keep, sell, or trade i still have those options.

 

so for all those reasons, i nearly backed out.. but i was offered a great deal which i may reveal later when it is done but you can estimate the cost yourself was approximately 75% off of an installed kit. best i can figure I'm getting the parts at or near their manufacturing cost and a free install.

small price to pay to be without my truck for a month and a little gas+ airfare.

i had considered that, and i will not say anything here that might void my warranty, but to your point i do lose 3 psi at my elevation and i know someone who has a quick change kit that makes swapping easy. if i did that my only intention would be to recover lost PSI at home and if i plan to travel swap to a stock size.

but ill make you this deal..

i do have an app on my iPhone and i just ran it stock a couple days ago so ill post those numbers here but first let me reference the denali guys times from another forum..

 

he ran according to his iPhone app and a handheld

 

0-60 in 6.06 and a 1/4 of 14.76 @ 100 (i was a little off)

 

with a tune and headers he managed

 

0-60 of 5.86 and a 1/4 of 14.25 @ 107mph

 

in comparason i managed

0-60 in 7.72 and a 1/4 of 15.98 @ 89.5 mph.

 

Pretty Pathetic! eh? i think a honda civic can manage that at sea level!

 

so my promise to you is i will post times when i get to california using the same method before and after the install so we can see on the same exact device what the improvement was. although the numbers may not be accurate the comparison will tell the whole story.

 

edit, BTW i noticed you have a duramax, my buddy has a 2008 and another friend has a 2007 or earlier with the same engine, i believe 6.6l turbo diesel.

​what do those trucks run in the 1/4?

the 2007 has a tune and he claims he picked up 100 hp. would would you guess it would run?

i ask because before the whole SC topic came up there was some chatter about his truck being faster than mine and i kinds doubt thats true.. do yo have any 411 on the subject?

Well, if it's set up properly using a good tuner they can lay down 530hp to the wheel with a lift pump.

 

If it's tuner only, no other mods to speak of. It will run high 13 (around sea level) maybe 14 flat. If he's got a lift pump, good tuning, exhaust/intake and some tie rod sleeves he could run mid 13. They can put down 1000ft-lbs with just a tuner. They are 7000lbs too. RCLB with built tranny, hot tune stock air/fuel will hit 12's no problem.

 

It would be a close race, it'll give you a good run for your money. They are no joke with a hot tune uploaded.

 

As for mine, it might run a 13 minute pass. Depending on how many guys are pushing it down the track. Lol

[bass mechanic]

good lord! I hope you know how to put that back together! looks like your truck puked the engine out like a bad night of sushi!

 

im guessing either a problem or major upgrade?

[travalan21]

When will this bad boy be done? lol sounds sweeeeeeeet!

Oh ya, pulled many engines. All the same crap ;p Duramax is just packed tight tho

 

Not fully diagnosed as of yet, but she's got a cracked piston or a hole in one. 60 psi of boost on stock internals lol

 

Lasted few years tho. Gettin built better now tho [emoji2]

[Jon A]

Now having said that the truck version actually makes more tq at 460 than the vette and less hp which tells be it's a matter of a different cam between the 2 engines.

 

It's actually the intake manifold that's different (the truck has one with much longer runners for more low end torque but that hurts top end power), they have the same cam. Once you remove the intake from both engines, you've basically equalized them. If you bolt on the same blower, you should expect roughly the same results at the flywheel but naturally less at the wheels due to the heavier drivetrain. But the gains over stock will actually be larger for the truck with an identical setup. Of course they may change things up a bit (a more conservative tune to be towing safe, etc).

 

That won't be the case with centrifugal blowers though--the Vette intake will allow them to make more top end power than the truck's intake.

 

BTW, C&D tested a CC Denali and it ran 14.1 @ 99 stock. http://www.caranddriver.com/reviews/2014-gmc-sierra-1500-62l-4x4-test-review

 

A tune all by itself will be worth several tenths even without any more power by getting rid of the torque management at launch and improving shift points.

 

 

Jon I see you're still reachin for that rainbow eh buddy?

 

There's nothing rainbow colored about facts and data. To the contrary, when cammed and blown 5.3's are already cracking 400 RWHP, claiming a cammed or blown 6.2 won't crack 400 is just...stupid? Ignorant? Dumb? I don't know, pick the word you like best.

 

Show me a time slip of a 5700 pound truck running into the the 12's with a cam only and I'll believe your ridiculous claims.

 

Asking to see timeslips of vehicles that do not exist yet is very convenient for you. These trucks have only existed a few months. I don't even know of anybody who has swapped cams in a truck 6.2 yet. Neither do you. Pretending since you haven't yet seen timeslips the potential doesn't exist is really a "ridiculous claim." Give us some time.

 

You like claims, I'll make one you'll love. Mark my words--write this down! Within a year, you will see 6.2 trucks if not crack, come very close to cracking 400 RWHP with bolt-ons and tune only. No cam, no blower. Give us some time, we'll see who has the last laugh.
