Wow how times have changed.

When I got my h/c package done in 2006 and reported my numbers of 420rwhp mustang dyno everyone was impressed.

420rwhp mustang dyno would be around 440rwhp dyno jet. Very stout in my opinion. Last time I knew it was very rare for a h/c ls1 to be much over 450rwhp...

Haha yes times have changed. Check out chrs1313's h/c/i auto that dyno's at 485rwhp stock bottom end.

Sounds like the h/c LS1 was running like ***, good kill.

UltraZLS1

iTrader: (13)

Yep...sure does.

It has 23k miles on it and will break the tires loose at 70mph.

I had a h/c ls1 also...his car feels just as strong as it did. I guess both h/c ls1 cars I have experience with run like ***. Lucky for me I guess I have never seen the light.

Wow. 485rwhp from an auto h/c ls1.

So why did they put an ls3 in the new camaro? You do realize that is higher than a h/c ls3 auto would dyno right?

485 rwhp is about average for a 6 speed h/c ls3 car.

You guys think I should do an ls1 swap and save some money by selling my ls3?



Whatever dyno/situation these guys are getting 460+rwhp with h/c ls1's with, a similarly modded ls3 would be showing well over 500rwhp.

I am talking average numbers on a mustang DYNO. Not the all time highest crazy number you could find. I just did a little more looking around and the first thread in the dyno comparisons shows some guys talking about their heads and 224 cam cars putting down 400-415rwhp.

Haha nah I think the LS3 has better potential. I just think that a well setup LS1 can run pretty strong too. There have been some manual LS1's to eclipse the magical 500rwhp mark. I did read a thread recently of an LS3 camaro hitting 500rwhp w/ a cam swap and boltons.

From what I am reading 450-460rwhp seems to be the max (most of the time) if we are talking massive cams in the 240 duration and very good heads such as trick flow or AFR. And some of the numbers I found were not on a mustang dyno.

I would still have to say an average h/c ls1 will dyno 420-430rwhp on a mustang dyno.


But whatever.....Im happy with my slow turd.

Hopefully I dont run into a real ls1 some day ...maybe ill have to do more than bolt ons when I do

There's no need to get defensive, it's common sense to question the outcome when two cars dyno relatively the same with one weighing 200+ pounds more (F-body 3500-3600 lbs vs. 2010' SS 3800-3900 lbs).

Good runs though!

Roll racing helped out the heavier 5gen, I think the races would be a different story from a dig.

I wouldnt doubt it if he got it set-up to hook in the future.

He is now talking a supercharger...but what he really needs first is a 12 bolt conversion and some better tires.
Should be a easy 11 second car with traction.

I would think my SS would be very close to 3800 flat or likely less with a full tank when compared to the 2SS curb weight of 3849 or 3860 depending on the source. I have a 1SS with full aftermarket exhaust which definitely dropped some weight. I also removed the air pump for another 10 lbs lol.

The numbers were from different dynos on different days so who knows. The difference could be more or less.

I do have a 15 hp and 30ft lb of torque advantage (on different dynos). I also only had 700 miles on the car when it was dynoed.

Most all cars pick up at least 10hp after break in. The car has right at 3k miles on it now so I wouldnt be surprised if it was in the 44x rwhp range now.

I dont doubt that people would question the outcome. I was slightly surprised myself. But if you really only look at the power to weight and the fact that it was from a roll...the race really isnt that hard to believe. His tune is also in question which may have contributed...I am sure it doesnt help.

My car only picked up 20hp from completely untuned to tuned. So best case scenario he would edge me out with a better tune.

A good running 420rwhp fbody is a mid 11 second car at 118+ mph.

You think something's not wrong with the fbody? If his tune is off, it's gonna hurt a lot more than the dyno numbers you cherish so much. Oh wait, you already said earlier in thread something was wrong with his car, thanks for proving my point.

Nice opinion.

Enjoy your LT1...

I believe the word your looking for is sarcastic or cocky, either one of them would fit better than defensive about now.

L99 seems to have the most potential out of all of them. It's so damn restricted I'm amazed It will even let me rev to 3k.

Not an opinion, that's a fact. You mad?

UltraZLS1

iTrader: (13)

Another fact. Bolt on 5th gens have gone 11's as well. I mentioned this earlier. Your comment really doesnt say much.

Yeah I never knew what a h/c ls1 was capable of. I am very mad/stunned with your post.
I have been a member here longer than you have. I have owned/built/raced both cars. Your opinion holds very little weight with me.

Thanks again for the input.

A bolt-on LS3 5th gen with traction driven by a competent drive should go high-mid 11's. I would say an H/C full weight LS1 is about the same and given the fact that he could use a tune it's not hard for me to believe the outcome. I love how many people think the LS3 SS is a turd. Puts a smile on my face when people catch up and ask "what's done to that thing". The problem is most people who go to the track in a 5th gen don't know how to drive it and run 14's.

Amen brother. Case in point, watch the video. It wasn't even that good of an ET for me either, I'm running in the low 11's now.

I wouldn't exactly use that as an argument when the difference between you two is only a year.

I haven't seen a Bolt-On 10' Camaro go mid 11's with bolt-ons, but maybe I'm mistaken. However, a H/C F-body running high 11's would be considered a very mild setup IMO.
