Dynamometer Results & Comparisons - Futral LS2

My car made 521hp 459 tq with cnc L92 heads, futral cam, and all the bolt ons on a stock bottom end six speed vette.

@ the wheels? What rpm?
Post the sheet

I'm guessing those numbers are at the crank and this was done on an engine dyno?

Or the chassis dyno is about 5000ft below sea level?

Yea that would be some very impressive numbers...what are the specs on the futral cam?!

Yes at the rear wheels. I don't get on here much so don't know how that compares to others that have done LS3 topend on a LS2 bottom end. The cam is 230/ 240 range and I will get the dyno sheet on here as soon as I can.

Congrats on your numbers man!! Hats off to FMS for specing out some powerfull combos!! I know i love mine!!! :cool:

That combo was nailed!! Stock bottom end LS2 making 40x stroker power

That thing is stout!!

Thanks guys, my goal was 515 rwhp with this build and Futral hit that on his first full pull. I just figured out my hp per CI and it 1.43 hp. I'm feeling real good now after I read the other thread on top ten hp per CI. ;)

Sweet, post full details-

Intake ported?
Headers?
Exhaust?
CAI?

All the details would be great :)

Nice work

Wow...

Stock intake ported by Futral, vararam intake, LG lontubes with ZO6 mufflers. I've always used Futral for cams, tuning, porting intakes and have always made very good power with all my vehicles. It's all about having the right combination to make power.

That's a lot of power for a ported intake and a pull only to 6600 rpm..... Idk Mayby it did its just tough for strokers with top end heads and 7000 rpm screaming big cam setups to make that power. But congrats.

Congrats, those are some great numbers and this will be the route I'll take.

People forget just how good Futral is :)

Nice!!!!

Nice! Another stout Futral combo.

Bingo ^^^ Futral gets the job done:judge:

Congrats OP!

Thoses numbers are really high!!!!!!

Thanks guys! Futral is one of the best in the business. He has a super mechanic besides himself (Terry) and very knowledgable people n his office (Charley). Good people to deal with.

This is real strong car

I keep seen the 6.0 engine is performing well with the l92 than the 6.2 engine
I have seen a guy made the same route, where the head is ported and mill to allmost 40 but not cnc, intake is stock ported with kooks headers and catback, cam (227/239) and with tuning made over 500rwhp (i think 512rwhp) & 470rwtq but alot says this is impossible.

When i saw his car, I made my project and even with the same cam spec., but the project equipments is a little different, it is on a LS1 bored to accept 4.0845" & stock cranshaft (3.622"), stock L92 but milled 15 (CR is almost 11.3:1), stock LS3 intake manifold, stock LS3 injectors, TB 102mm, headers 1 3/4" primaries with 3" collector, 3" cat back, UD pulley. I hope to get 480rwhp & 450 rwtq. The tuning will be after a week hopfully.

It is easy to make power with these motors, I put a 6.0 out of a 07 model new body 2500 which came with the L92 heads n my 06 1500. I put a pulley, cold air, full exhaust, and the Ls9 cam n it and it put down 410/405 through my factory 20's and the motor is only 9:1 compression. :burn:

Good heads and true duals are what put this baby so solid over 500 at the tire. Nice work, especially the torque!

Actually I think that is a bunch of lies. There is no way a stock bottom end ls2 is making 520rwhp. I have talked to several shops in the area and the most they can squeeze out of a N/a stock bottom end is in the 470 range with top of the line parts. There is no way that that combo put out that kinda of power. I assume, someone went into the motor and did something or someone was playing with the dyno somehow and is just using this as a clever ruse to sell some parts to 20 years olds with Visa cards. The power level is not consistent with what everyone else with similar type parts combinations is making. Even with an LS3 M6 car with great heads and cam combo is not going to make that much power N/a.

470 is NOT the limit of a stock bottom end N/A LS2. :rotflmao: I have a friend with an LS2 GTO that made 456 with just a mild cam and a FAST 102. The numbers are definitely higher than you'd expect, but maybe the combo was just nailed and just works. That's why dyno numbers should be taken with a grain of salt.

I'm interested to see the car back up the #s with some GOOD mph at the track.

My car put down 402 with cold air, full exhaust, and a tune on same dyno. Car went 12.0 @ 117 leaving easy. You do the math now u dumbass! Don't hate bc ur car don't make that power! LMAO!

My wives G8 GT "L76 / 6.0" made 452rwhp through the 6L80E stock bottom end and milled heads only with full bolt ons.

Lol you crack me up. I'm at Futral right now and a heads cam fast intake LS2 C6 just did 488 fresh off of the interstate. Go gag on something before saying dumb shit.

I kinda understand were he is coming from I dont think that 520 is possible with the combo presented by the OP. I know that 520 has been done out of a stock ls2 bottom end. My shop has done it with a head/cam/intake stock ls2 bottom end. But that was with meth injection more compression and a vacum pump and a ported fast 102/102. I do think that 480-490 in the op's car is possible. But my 402 with a better top end made 536/488 so it's hard to think a lesser combo came that close to my combo. But then again all dyno's are different so thats really hard to compare. Especially without all the specs of the build. I mean this combo doesn't even have a fast 102 intake?

Regardless I am sure the thing rips and and is crazy fun to drive!

This is another 2007 C6 M6 we just made some pulls on. Stock bottom end Trick Flow heads, Fast manifold, and full bolt ons. The customer installed the parts and hade someone else tune it.

Im guessing these guys are a bunch of Dyno Queens. I would like to see some time slips. I guess my other questions would be that if they were making these made up numbers how are the stock rod bolts holding up? If they were making those kinda numbers the rod bolts and powdered metal connecting rods would really not much of life span. I do believe that with a built 408+ CI combo getting in the 500 range is possible but is still difficult. The other issue I have the made up numbers is how bid of a cam are they running? I looked on the Futral website and he even says that anything beyond the F15 cam has issues with PTV clearance. So even with great heads I dont see how that combo even with an F15 cam and aftermarket heads is putting out 525. I can see maybe in the 460-470 range with a stock bottom end, but 525 just does not seem realistic.

Does a stock bottom end LS1 with 522+ rwhp through a 4l60e N/A running high 9's and on the back bumper sound realistic?

These numbers are more in line with what I have seen.

It's funny you mention 408 cause they just completed a 408 (he even posted a thread about it in this section) that made over 600rwhp. My car did 408rwhp bone stock with no tune. My trans am with a set of heads would have done over 500 easy. Seems like you need to do more research buddy.

yes but that 408 was at 14-1 compression on race gas. Not really a street motor. most 408 are in the 480-510whp range so yes 520 out of a stock bottom end ls2 is not the norm. especially with ported ls3 heads and a ported stock intake. I can see were that seems a bit high. Had is been worked TFS 225's with a ported fast 102/102 at 11.8-1 compression with a big cam then I can see those numbers happening.

But Dyno numbers can be different dyno to dyno. So if the car goes out and runs 130+ it's making some good power.

408's make more than 500 easily

My response is directed to the post by "techLs1" claiming Futral is lying about power numbers. If you want to make BIG power, get out your checkbook and call FUTRAL - otherwise refrain from posts which provide no value.

My old 408 made 552 at the tire with a FAST 92 intake. This was with 4800 stall and T-400 and Dana 60 rear. Dyno sheet attached. Allan Futral knows how to make big power - PERIOD. It is not cheap to do, but they have the secret sauce.

By the way, attached is my dyno sheet on the 415ci that made 614 at the tire. Again this was through a Neal Chance 5400 Stall, T-400 Transmission and a Dana 60 rear.

Some people always wanna make that claim that Futral is messing with the dyno or other nonsense but the fact is Allan knows his shit. That's why we call him the LS Whisperer down here.

Well, if you need to get out your parents checkbook to have your car worked on have at it. I'm just saying the numbers seem high and not realistic. I don't doubt that they are fine mechanics and know what they are doing, but for the given combo's they seem a little inflated. So Im saying post up your 1/4 times and let's see if those numbers are accurate. If they are real there should be nothing to hide. I could be wrong but would love to have someone explain how those high numbers are accurate other then just saying "X" shop rules. I welcome for someone to explain the engineering behind the science of those numbers vs. web-hype.

1/4 mile isn't always the determining factor because not everyone wants to maximize their suspension for great et's. My trans am made 640/580 and ran a 10.9 @ 132 with a measly 1.8 60'. It had ccw's on it with lowering springs and a handling suspension. If I was interested in maximizing my power I could have put drag suspension and slicks and skinnies on it but that didn't interest me all that much. I wanted big power but to not be one dimensional.

First, the working capital I'm using is not from my parents, but from the fruits of my own labor. Second, you claim someone is lying so they can sell parts and you make these claims based off what you have seen on the Internet. In both of your posts you use inflametory language to state a point of view which has no basis or foundation.

The original poster is very proud of the build and from my experience with Futral Motorsports, both parties should be very happy with the results. We are happy to have you at the site, but your baseless comments should be kept to yourself.

520 is very possible! thats only 605-610hp at the Flywheel in an M6 vette and a 364cid engine with 350+cfm heads should easily be able to do this built right with the supporting hardware!
No two combinations are the same and usually its the good shops that set the Standards that everyone else shoots for
I say Congrats Thats a Awesome Build! if you don't have anything positive to add keep it to yourself and Go build some Power for yourself That will keep ya busy;)

What is this with the parents check book?? I'm not a kid, I have a dynojet dyno for four wheelers. The only difference between mine n Allan's is the wheel. It's the same n the four wheeler world when I come out n beat someone with alot less motor they wine n cry saying I'm lying. If u don't believe us then put up some money and we will take the motor apart for u, if not move along and get ur parents to buy u something better. Maybe like a beige Volvo! :gtfo:

I have a 403ci LS2 motor with Trick flow 215cnc heads with some custom work and bigger intake valves, Ported fast 90mm and 90mm NW TB at 12.3-1 compression on the first dyno pull it made 450rwhp and 394rwt but ran a 10.57@128mph. Then we realized the car was 3 quarts low on tranny fluid. We topped off the tranny with the correct amount of fluid and ran the car again. Bam 10.39@129mph. (Now Futral didn't build this motor). Since then I have pulled the converter out and had it recut. The car now makes 551rwhp and 513rwt. (No new 1/4 times yet). I know the OP very well and I myself have had work done at Futral's shop. The dude knows how to make fast cars. (We are also at sea level. Which makes a difference). The op's stock bottom end LS1 Formula he use to have made something like 480rwhp N/A through a A4 tranny. I have no doubt that this car made this power.

My old stock bottom end motor that Allen built went 10.90@123mph N/A fullweight and with stock suspension..

Were the heads milled at all?! Very interested in this cam...

I would like to see the same car on a different dyno.

Any more details on the specs of this cam or is it a secret...?! I just picked up an L76 from a G8 GT and would love to make those kinda numbers

Heads were milled to 65cc to bring compression almost back to stock. Cam is 232/246

Im surprised that cam cleared with the heads milled but that's good to know. I'm assuming compression would be about in the 10.8/1 range then?! What about lift and LSA?!
