Dixonk(screenname)C5 Vette has a 408 with a big cam and trickflow heads, full exhaust(1 7/8" LT's) and a tune and only makes 522rwhp. I'd say this guy is a LSx god if he's doin' it on stock cubes.

Nice username haha

I have a feeling this guy is full of **** anyway. He says he has a 200 hit of spray, and that he should be pushing a little over 700 to the wheels with it. I don't think he has the power, but I don't know for sure.

Ok, I'm gonna get flamed to **** for this, but I don't think 550 HP (at the crank) is too tough to do w/ a NA LS1. Lets try the math and see how I do.
The HP ratings I'll list have been dyno proven, or so I've been told.

Stock SLP SS - 345hp
MSD Wires and NGK Plugs - 15hp
Royal Purple Oil - 10hp
SLP Loudmouth Exhaust - 20hp
GM Hotcam & LS6 Springs - 50hp
SLP Tuned Headers and Y-Pipe - 50hp

Now my math adds up to 490hp at the crank. Add in a tune and some good heads and I imagine you'd be around 550hp at the crank. Now putting that down at the wheels you'd probably have to upgrade the rotating assembly and do some major internal work, but I bet 550hp at the wheels isn't that hard. Just expensive.

Ok, put on the fire suit, here come the flamethrowers!

It makes sense on paper, but we all know the real world numbers vary.

thats true....15 hp for plugs and wires???? give me a break, this isnt a damn infomercial...

I see why you have your flamesuit on.

There are better choices for mods but even with those better choices you are not going to see 550 at the wheels, I'm sorry.

Except for the Stock SLP SS 345 HP, cut all those other HP numbers IN HALF AT LEAST. No freakin' way will headers and Y-pipe give you 50 HP and no way will the catback give you 20 HP. Headers/Y/Catback combined will net you about 30-35 HP total, but no where NEAR 100 HP. Wires and Plugs, 2 HP at best. Those are the whole "sum of the parts" things that help. The only thing that is maybe close to being right is the Royal Purple, but that would be adding that **** to everything from motor to trans to rear end to gain about 8-10 HP. And not saying the GM Hotcam is not a good performer, but in todays LS1 cams, it's a peanut of a cam that is barely bigger than stock.

I could see like a MS4 adding 50 HP to rear wheels and about 80 HP at the crank. GMHTP did an article when it first came out where it added ~ 82 HP at the crank. I could see the Hotcam maybe bumping up 50 at the crank so that would equal about 35 at the tires.

Apparently myself, Tyler and Lance are going to have to hook you up with that Toledo LS1 knowledge. LOL. Aren't you trying to do a swap soon?

no, there's no swap in my future. My current car is staying as is. I'm hoping on getting and LS1-2-3 someday, but that's not in my current plans anytime soon. But hey, any info you have would be great to read. I'm always up for learning as much as possible.

As far as my calculations, we'll wait and see. A good friend of mine has done almost exactly what I've listed above and I'm sure (after it gets a good tune) it'll get dyno tested. We'll see what it puts down then.

But as far as 550 RWHP on an N/A LS1 motor; technically you could run that on alcohol and probably get 800+ RWHP out of it. I still don't think it's a hard number to reach at all. It's just a matter of how much you wanna spend.

A stock cube n/a ls1 making 520 rwhp...I gotta get this guy to show me a dyno sheet and mod list.

one day ill build a forged 5.7 that makes 550 to the wheels. but i dont make enough moola

Outlawfireman

I'm originally from that area, and I know this guy. I haven't personally seen it since it came back from the shop. I do know that it is a 6 speed, and the people that I have talked to all seem to think that it has some monster cam. If he won't produce a dyno sheet, don't call him out just yet. When Summers last Blast rolls around invite him to run at the strip in Wichita Falls. By then I will have my set up done. I'll run him, and if he's puttin down 500+ and has the driver mod, he will beat me. If he doesn't than you know he's full of ****.

i have longtubes, ory, catback, those plugs/wires, and i'm probably only making 390 to the crank. that cam isn't going to add 100hp haha.

here's a more realistic list:
Stock SLP SS - 345hp
MSD Wires and NGK Plugs - 1.5hp
Royal Purple Oil - 1.0hp(maybe a little more)
SLP Loudmouth Exhaust + SLP Tuned Headers and Y-Pipe - 30hp
GM Hotcam & LS6 Springs - no idea but probably less than 50hp

i'd believe maybe 5 from plugs and wires, and a total of 30 from their full exhaust.

plus i believe their tuned length headers are designed to add more power down low than their longtubes, which would be the opposite of what you want for a dyno queen.

Here I go backing the craziness, but only on two points. Hot Rod did a royal purple comparo a couple years back where they changed oil, trans and rear gear fluid to royal purple and did nothing else, and gained 12 RWHP. So, if you're running Royal Purple throughout, there's an easy 10+.
Point 2, SLP long tubes plus LM2 gained a dyno proven 41.XX RWHP as claimed both by them and GMHTP. That would be what, 50+ on the motor? Just those two points though...someone already beat me to the MS4 idea.

iTrader: (37)

that's very interesting. i never would have expected that big of a gain from oil. or longtubes. that must have been one heck of a tune.

max_ta

This is why our ford freinds have to boost their cars themselves or the factory does it for them!THEY FEAR THE LITTLE LS1
hell the LS6 m6 has 385 @ the crank supposedly ???
any corrections here with Lotus's additions and what do you get

max_ta

ah damn it it was the vette LS6

I have lingenfelter take off heads, a baby 228/230 with .600 lift and I have to be around 450 to the wheels, thats with stock internals i haven't dynoed it yet but Im trapping 122 in the 1/4 and running 11.3s I dont see how 520 to the wheels isnt possible. Especially with a bigger cam and better heads it wouldnt be very streetable but i think its possible.

didnt the 345 hp SS already have the dual/dual catback??

Swift_01_z-28

iTrader: (1)

I know the slp ss had the Center mount exhaust. I just don't see a stock cube ls1 pulling that **** off. And btw, brandon, no doubt man we will see when the time comes. And one more thing, josh and cody damn sure don't know as much as they would like to think they do about lsx equipped cars. If you know anything about the guy, he's one of those types that everything he owns is the best of the best and can never be touched.
