Dynojet? Mustang Dyno? SAE, STD corrected? Sure some are stronger than others, but 300 rwhp is the norm for LS1 cars. That was my point.

 

I know, was just an example. A couple mods and a '95 GT would be in the mid 14s range.

 

Id love to see that seeing that stock 6spd LT1 Fbody's run 101-102 mph in the 1/4 ...Ive heard fairly tales also of LT1's running that stock, but the fact is for a stock one your not gonna see much better then a 13.7-8...Ofcourse you had the occasional 96-97 SS 6spd run a 13.6 when they 1st came out. My experience w/ newer Gt's weather it be a bad driver or not, my full bolt on/stall/gears 97 never had any problems w/ the 99 and up,wasnt even close...and the few I raced w/ my cai and cutout 323 96 car wasnt much different. The sohc doesnt respond very well to mods hence the aftermarket basically being at a stand still the last few years. Cmon Tim chime in and say the sohc does , your engine is FAR from stock. As for the HP TV dyno, they always dyno low on that show, they once dyno'd a 6spd c5 and pulled 260 something

 

I know it's a dynojet, but beyond that, they don't give much info. In fact, it never even showed if the car was an auto or stick. I know that's on the low side, but it's possible that there's a lot of those kind of turds out there....who really knows? Like everyone else said, I've seen them run as low as 101 at the track...and as high as 107. Put a car that traps 107 in the hands of a typical (non-drag racing) driver and you may only have a high 13 sec. car. Put one of us in that car and you've got a low 13 sec. ride. Personally I don't doubt what Steve says, but I think he's just been lucky so far

99 Z28 auto. Dynojet down in Tampa Florida at Dyno Tech. 279rwhp. Second run was 281rwhp. Both SAE corrected.


This was my car, I have the dynos and the video of the runs. The car trapped 101mph on its best. My 01 WS6 trapped 109.46 on the only run down the track (stock).

The plugs on the 99 were fried, (6K miles at the time of dyno) by changing them out for TR55s I picked up 3 mph and dropped 3 tenths. After that and the boltons (full exhaust and intake mods) the car pulled 321rwhp.

 

Ok. So a poorly running LS1 dynoed 280 rwhp. Given the 3 mph increase with the plug change, that's about right...somewhere in the 300-305 rwhp range. I didn't say it can't happen, just not the norm by any means.

 

97bowtie - You are not comprehending very well what other people are saying. I didnt say anything about NORMS i said not all LS1's come out of the factory with "360 hp" like everybody keeps saying in this thread. There are LS1's out there that have dynoed low, and put up high 13's at the track at 101 mph or so. Key words there SOME. Point of that was maybe steve ran a weaker LS1. You guys get some kind of inferiority complex whenever somebody even mentions the word LS1 in a kill story.

yellavette - I seen that same episode, there dyno seems to be pretty right on, they had a what 96GT that dynoed 180 rwhp, thats pretty accurate. As for the mod choice they make on the car projects they do

LeadSled1 - I wish i could have met you when you came down here with Tim. You still post some on EFA right?

Antz97ZNJ - Once again i said the BEST times LT1's have ran, never did i say running 13.4's@104+ is the NORM . There are freaks out there. The new GT's respond well to pullies, and gears. As for the rest of the boltons you are right, the SOHC 99+ GT doesnt like them too much.

Tim (1BadAzzGT) got a 14.0 run out of his 98 GT, most people ending up with high 14 second, low 15 second runs out of them. There are things that very from the norm.

 

I've never seen one go that fast even Best I've seen stock in my 40 or so trips to the track was 99 mph. Of course, there's very few stockers out there. Not saying it can't be done...but I've never seen it.

Yeah, I caught that one. Pretty funny. I laughed even harder when they baselined their civic (they were doing some budget buildup thing) and it made like 87 frhp. LOL. Even after bolt ons and NOS it only made like 150 fw or something. Why even bother?

Jason

 

I would love to see where thats documented or where you found that .Those times and especially those traps are unheard of for a stock LT1...fastest LT1 time ive seen period was a 6spd LT1 96 vette that ran a 13.4, and that was off fbody.com years back

 

I am comprehending 100% what you said. You made a point that not all LS1s come with 360 hp from the factory and that some may only have 315 at the flywheel. Of course there is going to be some variance, but the driver, conditions, as well as the running condition of the car will play a HUGE role in the car's performance. Poor maintenance is most likely the source of these 'weak' cars. You might find one here and there that rolls 280 rwhp or so (given poor running condition etc.), but it's not the norm and given it's rarity, it's irrelevant when comparing Steve's GT to LS1 cars (which is what this thread has become). Of course Steve ran poor running LS1s, or he wouldn't have stayed ahead for very long. That's just a simple fact. You/he may not want to hear it, but it's true.

I think the reason you see such a huge variance in the performance of the cars is the driver, conditions (huge factor), as well as how well the car was maintained.

I don't have an inferiority complex (it's a fkn car), I just don't agree with some of the BS being spewed. I would just like to see the look of disbelief when he finally runs a well running LS1 car. Back when my LT1 trapped 109 and I got pulled on by a LS1 WS6 with nothing but a lid, it became apparent which motor was better (in near stock/lightly modded form). My cammed LT1 had it's hands full with stock/lightly modded LS1 cars.

It's funny, when I had my LT1 and LS1 guys would come in these threads and say how a lightly modded LS1 can keep up with cammed LT1s etc. all the LT1 guys (including myself) would give the same 'typical LS1 owner' response. After ownign and driving a LS1 everyday for the past few months and seeing how well it performs, they were right. Not because they thought they were superior because they had a LS1 but because there really is no comparison between a LS1 and a LT1 in near stock form.

 

Yea that civic episode was indeed classic , That vette dyno was years back, id have to agree there dynos have been closer in the past year or so...gotta remember also, w/ all the lighting equipment,etc on the set its gotta be hot in there, plus i never seen a fan on the car when there actually making there pulls, so the lower #'s are understandable.

 

No such thing as a 96 LT1 6spd vette Antz. If it was a stick and a 96, it was an LT4.

Jason

 

My bad guess it was a 94 or 5, surely wasnt a LT4...

 

True, you never see any cooling done....but who knows what they actually do vs. what we see? I do remember them dyno'ing a silver SS as well, which made over 300 rwhp, but I don't remember if it had mods or not.
